Objective To explore the effect of smoking on pulmonary function parameters of male patients with chronic obstructive pulmonary disease (COPD) and to analyze the correlation between smoking and pulmonary function parameters. Methods From January 2014 to October 2015, the pulmonary function parameters of 223 male outpatients or hospitalized patients with COPD in the Department of Respiratory Medicine were retrospectively analyzed by using SPSS 17.0 software. The patients were randomly divided into smoking group (n=98), smoking cessation group (n=82) and non-smoking group (n=43). Results Various degrees of damage or abnormality of lung capacity, ventilatory function, gas exchange function and airway resistance (Raw) existed in the patients with COPD. Compared with smoking cessation group and non-smoking group, residual volume/ total lung capacity (RV/TLC) and Raw were significantly higher (P< 0.05), maximum ventilatory volume, ventilation reserve percent, forced vital capacity, the percent of first second forced expiratory volume compared its predicted value (FEV1%pred), maximum mid-expiratory flow (MMEF), forced expiratory flow 50%, forced expiratory flow 75% and diffusing capacity of carbon monoxide were significantly lower (P<0.05) in the smoking group. There was a negative relationship between MMEF, FEV1%pred and smoking index (r=–0.352, –0.381, P<0.05), and a positive relationship between Raw, RV/TLC and smoking index (r=0.403, 0.378, P<0.05). Conclusions Most of the male COPD patients smoke or used to smoke. Smoking leads to ventilation and gas exchange function decrease, small airway limitation aggravation, airway resistance and emphysema degree increase in COPD patients. Smoking index has a negative relationship with MMEF, FEV1%pred and a positive relationship with Raw and RV/TLC.
ObjectiveTo explore the effect of lidocaine on postoperative pain management after throat surgery. MethodsSixty patients undergoing throat surgery between June 2011 and May 2013 were randomly divided into trial group and control group, with 30 in each group. Patients in the trial group accepted lidocaine for pain management, while the control group used dicaine. Pain management effect was observed and compared between the two groups. ResultsThe pain scores of patients at hour 0.5, 2.0, 6.0, and 24.0 after surgery were 2.7±0.8, 2.2±0.9, 1.7±0.8, and 1.5±0.3 in the trial group, and 4.7±1.1, 4.2±0.8, 3.4±0.7, and 2.9±0.5 in the control group, and the differences were significant (P<0.05). Postoperative incidences 6.7% in the trial group, and 30.0% in the control group, and the difference was also significant (P<0.05). ConclusionLidocaine can reduce the pain of patients in postoperative pain management after throat surgery, with such advantages as long-time functioning, no toxic side effect, and obvious effect, which is worth promoting.
ObjectiveTo explore the levels of serum leptin,TNF-α,IL-8 and hypersensitivity C-reactive protein (hs-CRP) in stable COPD patients with different body mass index (BMI). Methods30 healthy controls with BMI 18.5 to 23.9 kg/m2 and 105 patients with stable COPD were recruited in the study. The serum levels of leptin,TNF-α,and IL-8 were determined by radioimmunoassay and hs-CRP level was determined by versatile biochemical automatic analyzer. The COPD patients were divided into a low BMI group (BMI<18.5 kg/m2,n=32),a normal BMI group (BMI 18.5-23.9 kg/m2,n=48),and a high BMI group (BMI≥23.9 kg/m2,n=25). ResultsSerum leptin level in the COPD patients was significantly reduced compared with the control subjects (P<0.05). Serum leptin levels were reduced in the low BMI and the high BMI groups compare with the normal BMI group [(7.89±3.16)ng/L and (10.52±5.98)ng/L vs. (13.04±5.73) ng/L,P<0.01 or P<0.05]. Leptin level in the low BMI group was lower than that in the high BMI group (P<0.05). Serum TNF-α levels were significantly increased in the low BMI group compared with the normal BMI and high BMI groups [(229.39±89.57)μg/L vs. (180.06±74.24) μg/L and (189.46±82.41) μg/L,P<0.01]. Serum TNF-α level in the COPD patients was significantly increased compared with the control subjects [(192.37±83.65) μg/L vs. (178.59±60.38) μg/L,P<0.05]. The IL-8 levels were not significant different among three BMI groups with COPD. The hs-CRP level in the high BMI group was higher than that in the low BMI and normal BMI groups (P<0.05). ConclusionLeptin and TNF-α may be involved in weight-loss of COPD malnutritional patients.
The "bnma" package is a Bayesian network meta-analysis software package developed based on the R programming language. The network meta-analysis was performed utilizing JAGS software, which yielded relevant results and visual graphs. Moreover, this software package provides support for various data structures and types, while also providing the advantages of flexible utilization, user-friendly operation, and deliver of rich and accurate outcomes. In this paper, using a network meta-analysis example of different therapies for androgenetic alopecia, the operational process of conducting network meta-analysis using the "bnma" package is briefly introduced.
ObjectiveTo explore the osteogenesis effect of advanced-platelet-rich fibrin (A-PRF) and β-tricalcium phosphate (β-TCP) composite. MethodsThirty-two healthy female New Zealand rabbits were randomly selected. A-PRF was prepared by collecting blood from middle auricular artery. Rabbits were randomly divided into 6 groups: groups A, B, C, D, and E (6 rabbits in each group) and group F (2 rabbits). Bone defects (6 mm in diameter, 8 mm in depth) were drilled into femur condyle of each rabbit’s both back legs. Then A-PRF and β-TCP composites manufactured by different proportion were planted into bone defects of group A (1∶1), group B (2∶1), group C (4∶1), group D (1∶2) and group E (1∶4) (V/V). The bone defect was not repaired in group F. The specimens were collected at 8 and at 12 weeks after operation. Then gross observation, X-ray examination, Micro-CT examination, and biomechanical test were performed. The bone volume/total volume (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), and trabecular spacing (Tb.Sp), compressive strength, and modulus of elasticity were calculated. ResultsThe gross observation and X-ray examination showed that the osteogenesis effect at 12 weeks was better than that at 8 weeks. At the same time point, the repair of bone defect and the formation of new bone in group B were better than those in other groups. Micro-CT examination showed that the trabeculae of new bone in group B were the most and the trabeculae arranged closely at 8 and 12 weeks. Besides there were significant differences in BV/TV, Tb.N, and Tb.Sp between group B and the other groups (P<0.05). There were significant differences in Tb.N and Tb.Th in group B, BV/TV and Tb.Sp in group C, Tb.Sp in group D between 8 weeks and 12 weeks (P<0.05). Biomechanical tests showed that the compression strength and elastic modulus of group B were the highest, and the compression strength and elastic modulus of group C were the lowest at 8 and at 12 weeks, showing significant differences (P<0.05). There were significant differences in compression strength and elastic modulus of each group between 8 weeks and 12 weeks (P<0.05). ConclusionThe A-PRF and β-TCP composite can repair femoral condylar defects in rabbits, and the osteogenesis is better in proportion of 2∶1.
