Objective Puerarin can remove inflammatory mediators, but the underlying mechanisms are not yet clear.The purpose of this study is to observe the synthesis of IL-6 in co-cultured bronchial epithelial (Beas-2B) and neutrophil cells, and to investigate the inhibitory effect of puerarin on IL-6.Methods Beas-2B and neutrophil cells were extracted and divided into six groups: neutrophil cells cultured alone (NC), Beas-2B cells cultured alone (BC), Beas-2B and neutrophil cells co-cultured (BC+NC), and Beas-2B and neutrophil cells co-cultured with puerarin at 50 μg/mL (BC+NC+P50), 100 μg/mL (BC+NC+P100) and 200 μg/mL (BC+NC+P200).The concentrations of IL-6 in different groups were quantitatively measured by ELISA and the expression of the IL-6 gene detected by real-time PCR.Results After 18 hours of culturing, the concentration of IL-6 was significantly increased in the BC+NC group ([280.409±21.340] pg/mL) as compared with those in BC ([240.002±23.727] pg/mL), NC ([22.771±1.146] pg/mL), BC+NC+P50 ([244.205±9.335] pg/mL), BC+NC+P100 ([218.168±18.635] pg/mL), and BC+NC+P200 ([179.539±7.340] pg/mL) (P<0.05), but lower in the BC+NC+P200 than in the BC+NC+P50 and BC+NC+P100 groups (P<0.05).The expression of the IL-6 gene was markedly up-regulated in the BC+NC group (1.515±0.013) in comparison with those in BC (1.000±0.215), BC+NC+P50 (0.398±0.024), BC+NC+P100 (0.332±0.016), and BC+NC+P200 (0.306±0.015) (P<0.05), but lower in the BC+NC+P200 than in the BC and BC+NC+P50 groups (P<0.05).Conclusion Direct-contact co-culture of Beas-2B and neutrophil cells significantly enhances the synthesis and release of the inflammatory mediator IL-6, which can be inhibited by puerarin.

Objective To investigate the reasonable proposal of prophylactic antibiotics use in plastic surgery with type Ⅰ incision.Methods The data of 748 patients with plastic surgery in our hospital were collected and the operation number was 770.Using a retrospective case-control study,we analysed the clinical effect of different administration methods.Results Clinical effects were compared among the multiple days medication group,normative administration group and no medication groups,and there was no significant difference in the prevention of postoperative infection results.Conclusions Plastic surgery with type Ⅰ incision does not need the prophylactic application of antibiotics.In special circumstances we should take medicine in strict accordance with the Guiding Principles for Clinical Application of Antibiotics.

Objective To investigate the effects of stimulation of CD40 on the growth,prolifera- lion and apoptosis of gastric cancer cell lines,and the change of gene expression profiles of gastric cancer cell AGS.Methods The growth and proliferation of AGS cells treated with different concentrations of soluble CD40 ligand were measured by MTT in order to choose optimum stimulating concentration of so- luble CD40 ligand.Cell cycle and apoptosis of AGS cells were analyzed by flow cytometry.Gene expres- sion profiles of AGS cells were analyzed by Affymetrix U133A 2.0 after treated with soluble CD40 ligand for 48 h.Results Two?g/ml of.soluble CD40 ligand was the optimum concentration.After being cul- tured with soluble CD40 ligand for 48h,the growth of AGS cell was inhibited and blockade in G1 phase. There were 414 alterative genes found in AGS cells including 209 up-regulated genes and 205 down-regu- lated genes.Forty-five genes varied significantly(P

Objective To improve the efficacy of the Nd : YAG laser-induced chorioretinal venous anastomosis in the rabbits'eyes. Methods Immediately after branch retinal vein occlusion (BRVO) model was made by argon laser in 40 eyes of 20 normal rabbits, the rabbits were divided into two groups. In the first group (experimental group), there were 10 rabbits treated with the argon laser followed by the Nd : YAG laser induced chorioretinal venous anastomosis. In the second group (control group), the rabbits were treated only with the argon laser induced chorioretinal venous anastomosis. Results An anastomosis in experimental group was formed in 6 rabbits within 4 - 6 weeks after treatment while no anastomosis was formed in control group. During 2 - 6 months the hemorrhage of retina or vitrous with laser photocoagulation were absorbed within 8 weeks and no other severe complications were found. Conclusion Applying Nd : YAG laser can improve the efficacy of chorioretinal venous anastomosis in the rabbils eyes.

Objective:To explore the anatomic repair strategy for congenital corrected transposition of great arteries (ccTGA).Methods:At the retrospective study, from August 2004 to May 2019, all 120 consecutive ccTGA were included and all accepted anatomic repair. There were 36 cases with with left ventricular outlet obstruction(LVOTO) and cardiac malpositon [ages(4.6±2.2) years, weight(17.7±5.9)kg] underwent the one and a half ventricle repair(hemi-Mustard and bidirectional Glenn procedures combined with the Rastelli), 49 cases[ages(3.4±2.7) years, weight(17.7±11.4)kg] underwent double switch operation(Great artery swtich with Senning operation), 24 cases [ages(5.7±4.3) years, weight(19.1±8.6)kg] with LVOTO and ventricular sept defect(VSD) accepted the Rastelli with Senning operation, and 14 cases with LVOTO and remote VSD [ages(6.9±4.8) years, weight(23.0±12.9)kg] accepted the Double root transposition(DRT) with Senning operation. Follow up data were collected by telephone interviews and echo. The median follow-up time were 49 months varied from 20 to 84 months, 46 months varied from 18 to 108 months, 35 months varied from 7 to 84 months and 98 months varied from 72 to 145 months. Statistical analysis was performed with SPSS 19.0.Results:There were 6 in-hospital deaths and 2 follow-up deaths. The survival probability were(84.0±6.0)% and(84.0±6.0)% at 5 and 10 years after operation. The probability of freedom from re-intervention were(95.0±11.8)% and(89.0±11.8)% at 5 and 10 years after operation. All 6 patients need implant pacemaker for Ⅲ A-V block. Seven patients had moderate or more than moderate tricuspid regurgitation. The left ventricular(systemic ventricle) EF were 0.61±0.09, 0.63±0.08, 0.59±0.01 and 0.65±0.07 in one and a half ventricle repair group, double switch(AS group), Rastelli with Senning(RS group) and DRT with Senning(DS group) patients. There were 1 heart failure in one and a half ventricle repair group, 1 in AS group and 1 in RS group. For 36 pure ccTGA patients, compared with direct double switch patients these patients accepting double switch after pulmonary banding(PAB) had more EF(0.54±0.09 vs. 0.65±0.08, P=0.00). There were significantly less patients need re-operation in one and a half ventricle repair group compared with RS group(0 vs. 13.6%, P=0.03). Conclusion:For ccTGA/LVOTO/cardiac malpositon, the one and a half ventricle repair was ideal strategy with significant less RV-PA conduit stenosis and re-operation. For pure ccTGA patients, second staged double switch after PAB had better long-term heart function. For ccTGA/ LVOTO/ remote VSD patients DRT with Senning was ideal strategy.

Objective To explore the impairment of attention network function in male patients with alcohol use disorder(AUD) and the main influencing factors of attention network function. Methods Forty-one patients with AUD after withdrawal therapy and 34 healthy controls (HC) matched with their demograph-ic data were selected as subjects of study. Attention function were assessed by attention network test (ANT). Results Compared with the healthy control group((30. 62±19. 74)ms,(98. 59±1. 46)%),there were sig-nificant differences in the reaction time of alerting network(t=-2. 479,P=0. 015) and the correct rate of the attention network test(t=-2. 074,P=0. 044) in the AUD group((17. 02±26. 42)ms,( 95. 07±10. 73)%). Pearson correlation analysis showed the alert network of AUD was negatively correlated with the age of first drinking(r=-0. 316,P=0. 044) and was positively correlated with the score of Penn alcohol craving scale (PACS) (r=0. 364,P=0. 019). The correct rate of attention network function in patients with AUD was negatively correlated with the years for education ( r=-0. 343, P=0. 028) and years for addiction ( r=-0. 337,P=0. 031). Linear regression analysis showed the attention network function of AUD patients was affected by the age of first drinking(β=0. 432,t=2. 079,P=0. 046),the years for addiction(β=-0. 555,t=-3. 127,P=0. 004) and years for uncontrol drinking(β=0. 309,t=2. 074,P=0. 047). Conclusion The AUD patients were demonstrated deficit in the alerting network. The impairment of attention function of AUD patients were influenced by their drinking condition.

BACKGROUND: Deep vein thrombosis (DVT) of the lower limbs is one of the severe complications of total hip replacement (THR)during the perioperative period. The incidence rate was high. The effect of primary disease on the DVT after THR in the elderly remains poorly understood.OBJECTIVE: To explore the effect of primary disease on DVT after THR in the elderly.METHODS: 147 cases with unilateral THR aged 64-93 years, were included and divided into two groups. Fracture group contained 68 cases, which of them were all traumatic femoral neck fracture ones. Osteopathia group contained 79 cases, and they had no traumatic injury. We selected total hip prostheses according to their physiological age, preoperative socialization ability,substantia ossea and life expectancy. Biological prosthesis in 5 cases and mixed prosthesis in 12 cases were used, while the others used bone cement prosthesis. If the patient had pain and/or swelling on the injured limb, with or without Homans/Neuhofs sign, we did the pressurized ultrasonic Doppler to examine whether the patient had got DVT.RESULTS AND CONCLUSION: In the fracture group, 32 cases had swelling in the injured limbs, and 20 cases with pain, 15 cases with Homans/Neuhofs sign, and 29 DVT cases were confirmed by the pressurized ultrasonic Doppler. One femoral neck fracture case of THR had no DVT clinical signs and was dead 17 days later. The autopsy found that it was an mixed type combined of pulmonary embolism; Osteopathia group: 20 cases had swelling in the injured limbs, and 11 cases of pain, 9 cases of Homans/Neuhofs sign, 20 DVT cases were confirmed by the pressurized ultrasonic Doppler. The blood coagulation state was greater, and the incidence rate of DVT in the lower limbs was greater in the fracture group compared with osteopathia group (P ＜ 0.05). These indicated that femoral neck fracture is a high risk factor for DVT development in lower limb affer THR in the elderly.
