Methods Different kinds of documents were widely collected, current developments of the diagnosis and treatmentof distal tibiofibular syndesmosis injury were summarized. Results The disease history (damage mechanism), cl inicalexamination, and imaging examination (X-ray, CT scan, and MRI) can assist the diagnosis of distal tibiofibular syndesmosisinjury. Patients with unstable distal tibiofibular syndesmosis injury needs active surgery treatment, and the princi ple isanatomical reduction and fixation so as to avoid the instabil ity of the ankle joint, long-term chronic pain, and traumaticarthritis. Conclusion The diagnosis of distal tibiofibular syndesmosis injury is still lack of specific quantitative parameters, socl inical study for large sample is needed to explicit the effectiveness.
Objective To investigate the CT imaging features of hepatic angiomyolipoma and its clinical characteristics. Methods The clinical, radiological, and pathological data of 3 hepatic angiomyolipoma (HAML) patients were retrospectively collected, and the imaging and diagnostic features were analyzed.Results All 3 cases were females, 2 complained of abdominal pain and one was absent of symptom. Both the laboratory examinations were normal in 2 cases, and hepatitis B virus markers were positive in one case. For CT features, the mass located in the superior anterior segment of the right hepatic lobe, in the posterior inferior segment of the right hepatic lobe, and in the left medial lobe, respectively. There were components of fat and soft tissue attenuation in these masses, and in which the CT value of the fat component was from -80 HU to -20 HU (mean -50 HU). There were enhancement in different degree and enhanced vascular imaging could be seen within the lesions. During surgery, all 3 masses were outgrowed from the hepatic lobes. Immunostainning showed HMB45 (+), αSMA (+), S100 (+)，which were bly suggestive of HAML.Conclusion HAML is a rare benign tumor with characteristic CT appearance, and its definite diagnosis relies on the immunohistochemical staining of HMB-45.
ObjectiveTo discuss the current status and progress of delayed gastric emptying (DGE) after pancreaticoduodenectomy (PD).MethodThe related researches about DGE after PD in recent year were searched and reviewed.ResultsThe etiology and pathogenesis of DGE had not yet been fully elucidated. There were various risk factors, such as the surgical trauma, advanced age, diabetes, and with other abdominal complications. The pylorus preserving PD didn’t increase the risk of DGE. The pylorus ring resection, anterior colon, Braun anastomosis, and minimally invasive surgery were beneficial for reducing DGE. Although there was no obvious progress in the treatment of DGE at home and abroad, the majority of patients could be cured by the symptomatic conservative treatment.ConclusionsPrevention is a main strategy for DGE after PD. Application of enhanced recovery after surgery might be a key to solve problem in clinical, but further research is needed.
Objective To explore the causal relationship between gut microbiota and urinary tract infections (UTI) using data from genome-wide association studies. Methods The gut microbiota data were sourced from the MiBioGen consortium, comprising genetic variables from 18 340 individuals. UTI data (ieu-b-5.65) were derived from the UK Biobank. Six methods including inverse variance weighted (IVW), Mendelian randomization (MR)-Egger, maximum likelihood, simple mode, weighted mode, and weighted median were employed for two-sample MR analysis on these datasets. Additionally, MR-PRESSO was used to detect and correct for heterogeneity and outliers in the analysis. Cochran’s Q test and leave-one-out analysis were applied to assess potential heterogeneity and multiple effects. Furthermore, reverse MR analysis was conducted to investigate causal relationships between UTI and gut microbiota. Results According to IVW method analysis results, bacterial genera Eggerthella (OR=1.08, 95%CI 1.01 to 1.16, P=0.034) and Ruminococcaceae (UCG005) (OR=1.10, 95%CI 1.01 to 1.20, P=0.022) were found to increase the risk of UTI, while Defluviitaleaceae (UCG011) (OR=0.90, 95%CI 0.82 to 0.99, P=0.022) appeared to decrease it. Reverse MR analysis did not reveal a significant effect of UTI on these three bacterial genera. Our study found no evidence of heterogeneity or pleiotropy based on the results of Cochran’s Q test, MR-Egger, and MR-PRESSO global test. Conclusion In this MR study, we demonstrate a causal association between Eggerthella, Ruminococcaceae, Defluvitalaceae and the risk of urinary tract infections.
Objective To estimate healthy life expectancy of residents aged 30 and above in Jianyang, Sichuan province, and comprehensively evaluate the health status of the population, so as to provide reference and basis for the formulation of health-related public policies. Methods The population data, death data and health status data of Jianyang city in 2018 were collected, and the self-rated health life expectancy and life expectancy without chronic diseases of residents aged 30 and above were calculated by Sullivan method, and their proportion in life expectancy was calculated. Results A total of 4 482 residents aged 30 years and above were included in Jinyang city, of whom 3 989 were self-rated healthy, accounting for 89.00% of self-rated health, and 1 988 were suffering from chronic diseases, with a chronic disease prevalence rate of 44.36%. In the age group of 30-64, the self-rated health life expectancy of women was significantly higher than that of men (P<0.05), and in the age group of 40-44, the life expectancy without chronic diseases of women was significantly lower than that of men (P<0.05), and the differences were not statistically significant when comparing different genders in other age groups (P>0.05). With the increase of age, the proportion of residents’ self-rated health and the proportion of life expectancy without chronic diseases in healthy life expectancy gradually declined. Conclusions The chronic disease has become the main factor affecting the health of middle-aged and elderly population, especially female population. It is suggested that active measures should be taken to deal with chronic diseases and the elderly health support system should be strengthened to improve healthy life expectancy of residents in Jianyang city.
ObjectiveTo observe the therapeutic efficacy of ultrasonic scalpel flap-retentiong surgery combined with automatic hemorrhoid ligation for the treatment of four degree mixed hemorrhoids. MethodsThe patients with four degree mixed hemorrhoids admitted to the Third Affiliated Hospital of Henan University of Traditional Chinese Medicine from January 2023 to June 2023 were included as the study subjects, then were randomly averagely divided into an observation group (underwent ultrasonic scalpel flap-retentiong surgery combined with automatic hemorrhoid ligation) and a control group (underwent Milligan-Morgan hemorrhoidectomy) by a random number table method. The therapeutic efficacy, total hospitalization time, operation time, intraoperative blood loss, wound healing time, hospitalization costs, postoperative pain score, bleeding score, wound edema score, postoperative complications (anal stenosis, urinary retention, anal incontinence), and recurrence were compared between the two groups. ResultsA total of 100 patients with four degree mixed hemorrhoids treated in this hospital were included, with 50 patients in each group. There were no statistically significant differences in the general information such as the gender, age, disease course, body mass index, hematochezia, and tumor prolapse between the two groups (P>0.05). ① The overall therapeutic efficacy both the observation group and the control group was well (100% versus 96.0%, Fisher exact test, P=0.495). ② The observation group had less total hospitalization time, operation time, intraoperative blood loss, hospitalization costs, and wound healing time as compared with the control group (P<0.05). ③ The differences in the interaction effects of the time-group for the points of postoperative pain, bleeding, and wound edema were not statistically significant (χ2=6.668, P=0.083; χ2=5.500, P=0.139; χ2=6.204, P=0.102). However, the main effects of group (χ2=5.073, P=0.024; χ2=7.107, P=0.008; χ2=8.857, P=0.003) and time (χ2=188.526, P<0.001; χ2=212.472, P<0.001; χ2=185.110, P<0.001) showed statistically significant differences. The points of postoperative pain, bleeding, and wound edema in the observation group were statistically lower than thoes in the control group (χ2=9.323, P=0.002; χ2=18.133, P<0.001; χ2=6.232, P=0.013). ④ The incidences of postoperative urinary retention and anal stenosis in the observation group were lower than those in the control group (P=0.046 and 0.031, respectively), there were no statistically significant differences in the incidences of incontinence and postoperative recurrence between the two groups (P>0.05). ConclusionFrom the preliminary research results of this study, ultrasonic scalpel flap-retentiong surgery in combination with automatic hemorrhoid ligation has a better efficacy in treating four degree mixed hemorrhoids, with a smaller wound, faster healing, higher safety, and fewer complications.
Objective To compare the effectiveness of anterior subcutaneous transposition and anterior submuscular transposition of the ulnar nerve in the treatment of cubital tunnel syndrome. Methods Between June 2006 and October 2008, 39 patients with cubital tunnel syndrome were treated separately by anterior subcutaneous transposition (anterior subcutaneous transposition group, n=20) and anterior submuscular transposition (anterior submuscular transposition group, n=19). There was no significant difference in gender, age, duration, and cl inical classification between 2 groups (P gt; 0.05). Results All incisions healed by first intention in 2 groups. In anterior submuscular transposition group, 17 patients (89.5%) had abruptly deteriorated symptoms after the symptom of ulnar nerve compression was abated, and 1 patient (5.3%) had cicatrix at elbow; in the anterior subcutaneous transposition group, 10 patients (50.0%) had disesthesia at cubital anterointernal skin after operation; and there was significant difference in the complication between 2 groups (χ2=9.632, P=0.002). The patients were followed up 24 to 36 months, 28 months on average. There was no significant difference in grip strength, pinch power of thumb-to-ring finger and thumb-to-little finger, or two-point discrimination of distal l ittle fingers between 2 groups (P gt; 0.05), but significant differences were found between before operation and after operation in 2 groups (P lt; 0.05). According to the Chinese Medical Society of Hand Surgery Trial upper part of the standard evaluation function assessment, the results were excellent in 5 cases, good in 12 cases, fair in 1 case, and poor in 2 cases in the anterior subcutaneous transposition group; the results were excellent in 6 cases, good in 10 cases, fair in 2 cases, and poor in 1 case in the anterior submuscular transposition group; and there was no significant difference between 2 groups (u=0.346, P=0.734). According to disabil ity of arm-shoulder-hand (DASH) questionnaires, the score was 22 ± 7 in anterior subcutaneous transposition group and was 19 ± 6 in anterior submuscular transposition group, showing no significant difference (t=1.434, P=0.161). Conclusion Both anterior subcutaneous transposition and anterior submuscular transposition have good effectiveness in treating cubital tunnel syndrome; and anterior submuscular transposition has less complication than that of submuscular transposition.
Objective To discuss the effectiveness of operation technique for antero-medial rotatory instability (AMRI) of the knee joint caused by motorcycle. Methods Between June 2007 and December 2009, 32 cases of AMRI caused by motorcycle were treated. There were 28 males and 4 females with an average age of 35.5 years (range, 20-50 years). The interval between injury and surgery was 5-10 days (mean, 7 days). The anterior cruciate ligament (ACL) was injured at the attachment point of the condyles crest; the medial collateral ligament (MCL) was injured at central site in 19 cases, at medial condyles of femur in 10 cases, and at medial condyles of tibia in 3 cases, which were all closed injuries. The bone avulsion of condyles crest was fixed by steel wire and MCL was repaired. Results Red swelling and a little effusion occurred at the incision in 1 case, and the other incisions healed by first intention. Traumatic arthritis of the knee occured in 5 cases. Thirty-two cases were followed up 16-22 months (mean, 18.5 months). The X-ray examination showed that the fracture union time was 5-8 weeks (mean, 6 weeks) after operation. At last follow-up, the extension of knee joint was 0° and the flexion of the knee joint was 110-170° (mean, 155°). According to the synthetic evaluating standard of International Knee Documentation Committee, 24 cases were rated as A level, 6 cases as B, 1 case as C, and 1 case as D at last follow-up. Lysholm knee score was 85.93 ± 3.76 at last follow-up, which was significantly higher (t=53.785, P=0.000) than preoperative score 37.54 ± 3.43. Conclusion In patients with AMRI caused by motorcycle, steel wire is used to fix the bone avulsion of condyles crest and MCL should be repaired simultaneously as far as possible. And associating with the early postoperative functional exercise, the short-term effectiveness is satisfactory, but long-term effectiveness still need further follow-up observation.
ObjectiveTo summarize the results of surgical treatment for 79 patients with coarctation of the aorta (CoA) combined with complex anomalies (CA) in recent years.MethodsThe data from 79 patients with CoA combined with CA admitted to Guangzhou Women and Children's Medical Center between January 19, 2010 and September 7, 2017 were collected and analyzed. There were 52 males and 27 females. The median age was 71 days, and the median weight was 4.3 kg. There were 26 patients combined with tracheostenosis and 7 patients with preoperative tracheal intubation. Extended end-to-side anastomosis was used to correct the CoA, and the associated cardiac abnormalities were treated simultaneously by an incision through median sternotomy. All operations were performed by the same group of surgeons.ResultsThe median deep hypothermic circulatory arrest was 18 (13-28) minutes, the median aorta cross-clamp time was 62 (15-199) minutes, the median cardiopulmonary bypass time was 145 (71-674) minutes, the median ventilation time was 72 (9-960) hours, the median length of ICU stay was 144 (12-1 944) hours, and the median length of hospital stay was 24 (2-93) days. Early death occurred in 9 patients and late death occurred in 5 patients. Reoperation occurred in 28 patients and recoarctation developed in 10 patients. After operation, transcoarctation gradient was reduced, and the transcutaneous oxygen saturation, C-reactive protein (CRP), lactate and creatinine were increased. Compared to the survival group, both preoperative and postoperative transcutaneous oxygen saturation were worse and the postoperative levels of plasma brain natriuretic peptide (BNP) and CRP were higher in the death group.ConclusionCorrecting the CoA and the associated CA simultaneously with extended end-to-side anastomosis by an incision through median sternotomy is effective and safe, and the outcomes of immediate and medial-term are satisfactory. Improving oxygenation and limiting elevation of BNP and CRP levels may reduce the death rate.
Objective To detect the contingent negative variation (CNV) in first episode deficit and non-deficit schizophrenia and the relationship between CNV and clinical symptoms. Methods Nihon Kohden evoked brain potentials machine were used to measure CNV in 60 patients with non-deficit schizophrenia (NDS), including 50 patients with deficit schizophrenia (DS) and 60 unrelated healthy controls (HC). Click-flashing paradigm was used to record the CNV and the differences among three groups were compared. The clinical status of patients with schizophrenia was determined using the Positive and Negative Syndrome Scale (PANSS). The overall functioning status was assessed using the Global Assessment of Functioning Scale (GAF). Partial correlations were computed to explore associations among the CNV in DS and the clinical data, controlling the sex, age, and education level. Results Compared to HC, both DS and NDS groups showed significantly reduced amplitude of B (F=27.38, P=0.00), significantly delayed reaction time (F=50.30, P=0.00). Compared to HC, the course of PINV in the DS group significantly shortened, while it was significantly delayed in the NDS group (F=15.32, P=0.00). Only in DS, when compared with that in HC, the latency of point A in CNV was delayed (F=61.01, P=0.00). There was no significant difference among three groups in both area of A-S2’ (F=2.34, P=0.10) and area of PINV (F=1.07, P=0.35). Amplitude of B and the course of PINV in the DS group correlated negatively with PANSS subscale of negative symptoms (r= –0.94, –0.89, respectively, Plt;0.05), whereas in the NDS group amplitude of B correlated negatively with PANSS subscale of positive symptoms (r= –0.87, Plt;0.05), but the course of PINV correlated positively with PANSS subscale of positive symptoms (r=0.88, Plt;0.05). Latency of point A in CNV, which was delayed in the DS group, correlated negatively with GAF (r= –0.48, Plt;0.05). Conclusion Generalized abnormalities of CNV existed in DS and NDS, while DS may cause more impairments in CNV than in NDS. The latency of point A in CNV may predict the social function outcomes of DS.
