Objective To evaluate the activities of daily living (ADL) and investigate its influential factor in primary angle-closure glaucoma patients.Methods One hundred primary angle-closure glaucoma patients (acute phase) diagnosed definitely from April to October 2014 were collected.The status of sex,gender,education,income were recorded.Barthel Index (BI),Hospital Anxiety and Depression Scale (HADS) and Glaucoma Quality of Life-15 (GQL-15) were respectively used to assess the ADL,anxiety and depression symptoms and visual quality of life in primary angle-closure glaucoma patients.At the same time the factors affecting ADL of primary angle-closure glaucoma were analyzed.Results There were no dysfunction in 12 patients,46 patients with mild dysfunction,32 patients with moderate dysfunction and 10％ (10/100) patients with severe dysfunction.BI was negatively correlated with anxiety and depression score,GQL-15 results and disease course (r=-0.819-0.395,P ＜ 0.01),and positively correlated with average monthly income (r=0.453,P ＜ 0.01).There were no correlation with gender,sex and education (r=-0.159-0.172,P ＞ 0.05).Conclusions ADL of primary angle-closure glaucoma patients has varying degrees of dysfunction,and disease course,average monthly income,anxiety,depression and visual quality of life are closely related with it.

This paper focuses mainly on the study of optimal fermentation conditions of S-adenosyl-L-methionine.Effects of carbon sources,nitrogen sources,inorganic constituents,growth factors and adding time of L-methionine on the yield,the content and biomass of S-adenosyl-L-methionine are studied.And ingredients of the culture medium are also optimized by the method of uniform design.The final optimum culture medium contains: glucose 30 g,Yeast powder 11 g,(NH_4)_2SO_4 12 g,K_2HPO_4?3H_2O 5 g,KH_2PO_4 10 g,MnSO_4?H_2O 0.09 g,ZnSO_4?7H_2O 0.14 g,MgCl_20.5 g,CaCl_2 0.3 g,CuSO_4 0.005 g per liter. Using that optimum culture medium,the yield of S-adenosyl-L-methionine can reach 0.9 g/L in Erlenmeyer flask which is 30 % higher than before.Experiment on 5 L fermenter reveals that the accumulation of S-adenosyl-L-methionine can reach 2.66 g/L.Biomass is 23.4 g/L.

Objective:To explore the reliability of Xpert MTB/RIF (Xpert) in the diagnosis of pulmonary tuberculosis and to understand the characteristics of retreated patients, so as to provide clues for the investigation of retreated patients.Methods:905 patients sputum with suspected tuberculosis from July 2019 to December 2019 were collected from the Tuberculosis Department of Changsha Central Hospital. Xpert was used for rapid screening of tuberculosis. MGIT960 and Roche culture method were used for rapid sputum culture and drug sensitivity, respectively. Rifampin (RIF) resistance was compared between Xpert and Roche culture. The gender, age, RIF resistance, occupation and diabetes mellitus of patients with positive Xpert were compared, and the risk factors of RIF resistance were analyzed by binary logistic regression.Results:The total detection rate of Xpert was 28.7%(260/905) in 905 suspected pulmonary tuberculosis patients; RIF resistance rate accounted for 20.8%(54/260) in 260 positive patients, and the main mutation types were probe-E and probe-D. There was no significant difference between traditional drug sensitivity and Xpert method in RIF resistance detection ( P>0.05); There was no significant difference between Xpert method and traditional drug sensitive cases in predicting isoniazid (INH) resistance ( P=0.293); there were significant differences in age ( t=-3.835, P<0.05), gender, RIF resistance rate and proportion of farmers between newly treated and retreated patients (χ 2=5.091, 16.862, 4.808, P<0.05); Binary logistic regression showed that retreatment was a risk factor for RIF resistance ( OR=3.739, P=0.004). Conclusions:Xpert has high clinical value in the diagnosis of pulmonary tuberculosis and RIF resistance; The retreated patients were older, and the proportion of male farmers was larger, with higher resistance rate to RIF.

Objective:To explore the prophylactic efficiency of dexmedetomidine on postoperative nausea and vomiting (PONV) in highly susceptible patients.Methods:By using randomized and double-blind controlled trial, 100 non-smoking female patients receiving laparoscopic surgery were selected and randomly divided into dexmedetomidine group and control group.The dexmedetomidine group received 0.6 μg/kg dexmedetomidine before induction, and 3 μg/kg dexmedetomidine after surgery.The severity of PONV, the visual analogue scale (VAS)for pain scores, the use of rescued antiemetic and analgesic drugs were assessed for 48 h postoperatively.Results:There were 93 patients completed the study (47 cases in dexmedetomidine group and 46 cases in control group).The number of patients classified as PONV 0 in dexmedetomidine group was significantly more than that in the control group during the time interval 0 to 6 h postoperatively (37 vs 27, P<0.05).The percentage of the usage of antiemetic drugs within 48 hours in dexmedetomidine group was lower than that in control group(25.5% vs 47.8%,P<0.05).During the time intervals 6 to 24 h and 24 to 48 h, the pain scores were significantly lower in dexmedetomidine group compared with control group, 2.9±0.9 vs 3.4±0.7 and 2.7±0.6 vs 3.0±0.7, respectively (P<0.05).Conclusions:Dexmedetomidine used perioperatively might decrease the severity of PONV in early phase postoperatively in highly susceptible patients, and reduce the need for antiemetic drugs and improve the analgesia effects.

Objedtve To summarize the experience of single-stage repair of coarctation of aorta(CoA) or interrupted aortic arch (IAA)and associated intracardiac defects through median stemotomy.Methods From Jan 2007 to Jul 2008,a total of 24 pa-tients with CoA or IAA and associated intracardisc defects were surgically repaired in single-stage through median stermotomy,inchud-ing 9 coanctation of aorta,12 coarctation with aortic arch hypoplasia,and 3 interrupted aorlic arch,.The associated intracardiac de-fects were Taussing-Bing anomaly 4,non-restricted VSD 22,subaortic stenosis 1 and pulmonary vein stenosis 1.The age ranged form 1 to 99 months (average 16 months) and the body weight ranged from 4 to 19 kg(average 9.3 kg).Aortic arch reconstruction was performed by hypothermic continuous low flow bypass using regional perfusion for all patients.Three patients with LAA and 9 patients with CoA underwent end-to-end ansetomosis.Of the 12 patients with coarctation and aortic arch hyipoplasia,8 patiellts underwent ex-tended end-to-end anastomosis,2 patients underwent end-to-side anastomosis and 2 patients underwent aortoplasfy.Results 2 cases were dead. One infant with Taussig-Bing type heart was dead of severe infection after 47 days postoperative,the other one who associ-ated with LAA and VSD dead of pulmonary hypertension crisis due to pneumonia after 15 days postoperative.No patient presented neu-rdogieal complication and renal insufficiency during the perioperation.2 cases presented recurrent respiratory problem.During the 18months follow-up,no patient presented with recoarctation except one with pressure gradient more than 20 mm Hg.Conclusion Pa-tients with coarctation of aorta or interrupted aortic arch and associsted intracardisc defects should be surgically treated as early as pos-sible when diagnosis was mode.Single-stage sortic arch reconstruction through median stemotomy using continuous regional perfusion is an effective and safe procedurd.Sufficient resection of ductus,extensive dissection of thoracic vessels and optimal tissus-tissue anas-tomosis techmique are very important for successful repair and avoiding recoarctation.

· AIM: This study was designed to evaluate the effectiveness of anterior lens capsule inclusion in combined trabeculectomy and cataract surgery in preventing scar formation of the filtering bleb in rabbit model.· METHODS: Twerty-Four eyes (12 rabbits) with glaucoma model were studied, anterior lens capsule inclusion in trabeculectomy with the small-incision cataract surgery were performed on all right eyes (experimental group) and no implants were applicator in trabeculectomy with the small-incision cataract surgery on all left eyes (control group). These operated eyes were followed up from day 1 to 6 months postoperatively. Intraocular pressure (IOP) was measured and filtering blebs were observed after surgery. Other main outcome measures: cornea、conjunctiva、formation of the anterior chamber, anterior chamber depth、inflammatory reaction、achievement ratio of operation and complications were analyzed. On week 1, 2, 4, 12 and 24 after surgery the animal were killed in batch. Tissue was harvested from the bleb area and was made pathological section. HE staining、light microscope and micro photo analysis technique were applied to observe the cytological and histopathologic characteristics of the filtering tunnels.· RESULTS: There were significant differences between the two groups on IOP (1, 2, 4 weeks)、filtration bleb, achievement ratio of operation and complications. In experimental group, at the first month postoperatively, anterior lens capsule absorption started with inflammatory characteristics. The peak of inflammatory reaction occurred 1 week after operation and all the cells in the filtrating tunnel disappeared 6month after surgery. The fibroblast proliferation in control group occurred at I week and the filtrating tunnel closed with angiogenesis at 1 month after surgery. Fibroblast proliferation started 1week after surgery with no statistical difference during the time course (P ＞0.05). Significant statistical differences were observed by comparing the fibro blasts numbers per unit area in the filtrating tunnel in experimental group and those in control groups (P＜0.05).· CONCLUSION: Anterior lens capsule was totally absorbed at 6 months postoperatively. Anterior lens capsule inclusion in trabeculectomy with cataract surgery can possibly control intraocular pressure effectively, long-term sustainability of functional filtration bleb, inhibition of the proliferation of fibroblasts and opening of the filtrating pathway in the experimental animal models were satisfied. Compared to the control group, anterior lens capsule application has less complication.
