Objective To investigate the effectiveness of ipsilateral digital proper artery dorsal branch flap to repair mid-phalanx degloving injury with distal segment finger defect. Methods Between February 2013 and July 2016, 11 cases (11 fingers) of mid-phalanx degloving injury with distal segment finger defect were treated. There were 9 males and 2 females with an average age of 33.6 years (range, 18-59 years). The injury caused by twisting in 8 cases and crushing in 3 cases. The injury located at index finger in 3 cases, middle finger in 6 cases, and ring finger in 2 cases. The skin avulsion was from proximal interphalangeal joint in 1 case, proximal 1/4 of mid-phalanx in 6 cases, and 1/2 of mid-phalanx in 4 cases. The area of wounds ranged from 4.0 cm×1.7 cm to 6.2 cm×2.6 cm. The interval between injury and operation was 2.5-6.0 hours (mean, 4.5 hours). All defects were repaired with the ipsilateral digital proper artery dorsal branch flaps. The size of flaps ranged from 4.4 cm×1.9 cm to 7.0 cm×2.9 cm. Nerve anastomose was carried between digital proper nerve dorsal branch in the flap and digital proper nerve stump in the wound. The donor sites were repaired by skin grafting. Results Tension blisters of the flap and partial necrosis occurred in 1 case, and healed after dressing change. The other flaps and skin grafting survived, and wounds healed by first intention. All patients were followed up 6-18 months (mean, 16 months). The texture and appearance of all the flaps were satisfactory. At 6 months after operation, two-point discrimination of flaps ranged from 7 to 10 mm (mean, 8.5 mm). At last follow-up, according to the functional assessment criteria of upper limbs by the Branch of Hand Surgery of Chinese Medicine Association, the results were excellent in 10 cases and good in 1 case, with the excellent and good rate of 100%. Conclusion The ipsilateral digital proper artery dorsal branch flap is a good method to repair mid-phalanx degloving injury with distal segment finger defect for the advantages of simple operation, less damage in donor site, high survival rate of the flap, and good feeling recovery of the finger.
ObjectiveTo analyze the trends of incidence, mortality, and burden of disease of cervical cancer in Chinese females from 1990 to 2019.MethodsThe global burden of disease database (GBD) and China health statistics yearbook data was used to analyze the incidence, standardized incidence, mortality, standardized mortality, urban and rural mortality, and burden of cervical cancer among Chinese females using Excel, SPSS 21.0 and Joinpoint Regression Program 4.8.0.1.ResultsThe standardized incidence of cervical cancer among Chinese females increased from 9.21/100 000 in 1990 to 12.06/100 000 in 2019, and the standardized mortality decreased from 8.40/100 000 to 7.36/100 000. The standardized mortality of cervical cancer in 2018 decreased when compared with 2015 in both urban and rural areas. Changes in age-group incidence and mortality indicated that there was a younger trend in cervical cancer. The disease burden indicators (DALY, YLL, and YLD) were increased from 86.49, 84.01, and 1.52 ten thousand person/years to 162.22, 157.40, and 4.83 ten thousand person/years, in which the YLD increased the most (217.76%). The APC of DALY, YLL and YLD were 2.39%, 2.56% and 4.25%, respectively. The proportion of cervical cancer disease burden in female cancer increased in 2019 compared with 1990. And DALY, YLL and YLD increased in the age group of 40 or over, in which DALY of the age group 50-54 increased 167.15%.ConclusionsThe situation of cervical cancer is not optimistic in China. Although the mortality of cervical cancer has decreased in recent years, the number of cases and mortalities is still increasing. Not only the burden of disease is continuously increasing, there is also a younger trend in cervical cancer. Active preventive measures should be taken to reduce the burden of cervical cancer.
ObjectiveTo systematically review the disease burden of pneumoconiosis in Chinese population so as to provide references for health resources allocation and health policy making.MethodsDatabases including PubMed, EBSCO, Web of Science, CNKI, WanFang Data and VIP databases were searched for studies on investigation of the disease burden of pneumoconiosis in Chinese population from inception to 31st January, 2020. Two reviewers independently screened literature, exacted data, and assessed risk of bias of included studies. Systematic review was performed on data of pneumoconiosis associated population, mortality, and disease burden.ResultsA total of 26 studies were included. Qualitative analysis showed that the decrease of DALY and YLL of pneumoconiosis in China had been lower than that in globally, and the increase of YLD had been higher than that in globally in recent 10 years. 14 factors were included in the analysis of influencing factors on the financial burden or hospitalization expenses of pneumoconiosis patients; among them, the length of hospitalization, related complications, and pneumoconiosis stage were the most important indexes which had influence or difference on patients’ financial burden (or hospitalization expenses). The burden of pneumoconiosis in the Chinese population was primarily concentrated on males. Occupational diseases caused most of them, and middle-aged and older adults were the primary population for pneumoconiosis. However, young patients due to early-onset age, long course of disease and complications, and other factors resulting in a larger YLD phenomenon should also be considered.ConclusionsThe disease burden of pneumoconiosis patients in China is still heavy. It is recommended to continue to reduce the DALY of pneumoconiosis among the Chinese population as a long-term goal, and to strengthen control strategies to curb the early onset and death of pneumoconiosis.
ObjectivesTo investigate the ability of emergency medical rescue personnel in Sichuan province to collect information and contact resources at rescue sites, and to provide evidence for emergency training and drills. MethodsThe rescue site of a batch of critically ill patients in public emergency was simulated. The cross-sectional survey was made on rescue personnel at the city (prefecture) and county level of Sichuan province. The rating scale of on-site information contact ability was used to evaluate their performance. Because the score distribution does not conform to the normal distribution, the space between the median and interquartile was used to describe the score, and multiple measurement data was compared by the rank sum test. ResultsA total of 287 rescue drill personnel were included. The overall score M (P25, P75) of information contact ability was 19.57 (13.04, 28.26). The scores of each dimension were as follows: the safety zone was set as 0 (0, 10), the on-site hazard identification was 0 (0, 16.67), external contact and coordination was 50 (0, 50), internal coordination and command was 50 (16.67, 50), the on-site disaster statistics was 40 (10, 70), the on-site resource status was 0 (0, 0), and the on-site reinforcement demand was 0 (0, 0). Hierarchy by occupation: 19.57 (12.50, 28.26) for clinicians, 19.57 (14.13, 34.78) for nurses, 25 (14.67, 32.61) for medical skills, 21.74 (14.13, 30.44) for public health doctors, and 17.39 (9.78, 21.74) for health management. Hierarchy by titles: 21.74 (13.04, 28.26) for intermediate level, and 17.39 (10.33, 23.91) for advanced level. Scores of different dimensions, occupations and titles were compared respectively, and the differences were statistically significant (P<0.05). ConclusionsThe results of this survey show that the emergency medical rescue personnel at the city (prefecture) and county level of Sichuan province have insufficient overall ability to contact information on site, so those with insufficient ability need to be trained. The training focuses on the on-site resource status, on-site reinforcement demands, safety zone setting and the ability to identify on-site hazards.
Objective To explore the relationship between imbalance in sagittal plane as well as structural factors and lumbar degenerative disease. Methods Patients diagnosed between July 2012 and May 2015 were divided into 4 groups according to corresponding diagnostic criteria: lumbar disc herniation group (LDH), lumbar disc protrusion group (LDP), degenerative lumbar spondylisthesis group (DLS) and nonspecific low back pain group (NLBP); 40 patients were included in each group according to their visiting time. All patients underwent X-ray, CT, and MRI. Sagittal parameters and evaluate degeneration level of structural factors were measured, and the difference among the groups were analyzed. Results There was statistical significance in differences of pelvic incidence (PI) and lumbar lordosis (LL) among 4 groups (P<0.05). Average PI was followed in descending order: DLS, LDP, NLBP, and LDH; average LL was followed in descending order: DLS, NLBP, LDP, and LDH. There was no statistical differences in sacral slope and pelvic tilting among 4 groups (P>0.05). The difference in the level of lumbar disc degeneration between NLBP group (which had slightest lumbar disc degeneration) and the other groups was significant (P<0.001) while no statistical differences in level and rate of lumbar disc degeneration among the other three groups was found (P>0.05). As to the level of lumbar zygapophyseal joint degeneration, there was statistical differences between NLBP group (which had the lowest level of lumbar zygapophyseal joint degeneration) and the other groups (P<0.001) while no statistical differences in the grade of lumbar zygapophyseal joint degeneration among the other three groups (P>0.05). There was statistical differences in the rate of lumbar zygapophyseal joint degeneration between LDH and DLS group (χ2=11.429,P=0.001). Conclusions Vertical lunbar spine is combined with LDH of which the level of lumbar zygapophyseal joint degeneration is minimized, while crooked lunbar spine is combined with DLS of which the level of lumbar zygapophyseal joint degeneration is maximization. NLBP has the lowest level of degeneration of lumbar disc and lumbar zygapophyseal joint degeneration.
Objective To explore the morphological characteristics of the postero-superior protuberance of the calcaneus and to explore its relationship with Haglund malformation. MethodsAnkle lateral X-ray films of 391 hospitalized patients between May 2021 and June 2024 were retrospectively collected. The morphological parameters of the postero-superior protuberance of the calcaneus were measured, including the length of the base, the height of the base, and the tip angle of the postero-superior protuberance of the calcaneus, and the morphological types were classified according to the above parameters, including the peak type, the hill type, and the flat type. The related parameters of Haglund malformation were measured, including Fowler-Philipp angle (FPA), calcaneal pitch angle (CPA), parallel pitch line (PPL), Chauveaux-Liet angle (CLA), and X/Y ratio (total calcaneal length/length of greater tuberosity of calcaneus). The differences of the morphological parameters of the postero-superior protuberance of the calcaneus and the related indicators of Haglund deformity among the three types and between the males and the females were compared and analyzed, and the differences of the positive numbers of the related indicators of Haglund deformity among the three types were compared. ResultsAccording to the morphological parameters of the postero-superior protuberance of the calcaneus, there were 64 cases of peak type, 245 cases of hill type, and 82 cases of flat type. There was no significant difference in the length of the base of the postero-superior protuberance of the calcaneus, CPA, CLA, and X/Y ratio among the three types (P>0.05). Among the three types, the peak type had the largest FPA and the flat type had the smallest (P<0.05); the peak type had the smallest tip angle of the postero-superior protuberance of the calcaneus and the flat type had the largest (P<0.05); the positive rate of PPL in the hill type was significantly higher than that in the peak type and flat type (P<0.05); the height of the base of the postero-superior protuberance of the calcaneus in the flat type was the smallest (P<0.05). FPA, CPA, CLA, PPL, and X/Y ratio were positive in 2, 42, 172, 142, and 77 patients, respectively. There was no significant difference in the number of positive Haglund deformity indicators among the three types (P>0.05). There was no significant difference between male and female patients in the tip angle of the postero-superior protuberance of the calcaneus, FPA, the positive rate of PPL, and X/Y ratio (P>0.05). The length and the height of the base of the postero-superior protuberance of the calcaneus, CPA, and CLA in male patients were significantly higher than those in female patients (P<0.05). ConclusionThe postero-superior protuberance of the calcaneus can be divided into three types: the peak type, the hill type, and the flat type. The peak type is more likely to suffer from Haglund deformity, and the males are more likely to suffer from Haglund deformity than the females.
Objective To summarize manifestation, imaging characteristics, and treatment of hepatic focal nodular hyperplasia (FNH). Methods From January 2007 to December 2016, the patients pathologically confirmed hepatic FNH were included in this study. The clinical features and imaging characteristics were analyzed retrospectively. Results Twenty-two cases were pathologically diagnosed as hepatic FNH with an age of (36.8±11.2) years (range from 20 to 61 years). Ten were males and 12 were females. Three patients had abdominal pain and 19 patients had no symptoms. The diameter of the lesions was (4.16±1.92) cm (range from 1.0 to 7.8 cm) and approximately 9 (40.9%) lesions were more than 5.0 cm. The diagnosis rates of CT and MRI were 64.70% (11/17) and 84.21% (16/19), respectively. All the patients underwent hepatectomy successfully and recovered without severe complications. No recurrence and metastasis happened during following-up of 1–103 months. Conclusions Hepatic FNH is more common in young patients and has no typical symptoms. MRI is useful in diagnosis of hepatic FNH.
