Puerarin is one of the most important effective components of Pueraria lobata which exhibited classic estrogen-like biological activities and had remarkable cardiovascular protections in vivo and in vitro experiments. These protections of puerarin are mainly exhibited on improving the myocardial cells membrane potential and arrhythmia based on effecting the Na+, K+ , and Ca2+ channels,resisting myocardial fibrosis damage, diastolic effect on blood vessels, promoting angiogenesis, resisting calcification and atherosclerosis, improving blood flow, antiplatelet aggregation, reducing lipid and resisting diabetes. The main mechanisms are to improve the membrane potential and reduce cardiovascular damage caused by inflammation, oxidative stress and apoptosis, and the main regulated signal pathways are the PI3K/Akt, the NF-kappa B and the caspases.

Total 2625 cases of pulmonary sequestration were collected from literatures of Chinese National Knowledge Infrastructure from 1998 to 2008. The age, gender, clinical symptoms, chest CT scan,chest X-ray findings, lesion location, supplying artery, venous reflux, and preoperative misdiagnosis of 2625 cases were retrospectively reviewed. The male: female ratio of all cases was 1.58: 1. The main clinical symptoms of pulmonary sequestration were cough, sputum, fever, hemoptysis and chest pain, but 13.36% patients were asymptomatic. Chest CT scan showed pulmonary massive lesions (49.00%), pulmonary cystic lesions (28.57%), pulmonary cystic-solid lesions ( 11.57% ), and flaky shadows (7.96%). Pulmonary sequestration mainly located in the lower lobe; 66. 43% located in the left posterior basal segments, and 20. 16% located in the right posterior basal segments. Pulmonary sequestrations were divided into three types, intralobar sequestration (83. 84% ), extralobar sequestration ( 16.03% ), and mixed sequestration (0.13% ). The arterial supply was mainly from branches of thoracic aorta (76. 55% ) and abdominal aorta (18.47%). The clinical manifestations of pulmonary sequestration were various, so the preoperative misdiagnosis rate was as high as (59 ± 20) %. We should take full advantage of clinical symptoms, imaging findings and location characteristics to improve the preoperative diagnosis rate.

Objective To evaluate the timing,feasibility and necessity of early laparoscopic cholecystectomy (LC) in management of patients with mild to moderate acute pancreatitis with gallbladder stones.Methods The clinical data of 75 patients with mild to moderate acute pancreatitis and gallbladder stones treated from September 2010 to August 2014 in our hospital were analyzed retrospectively.32 patients underwent LC within 48 hours of the pancreatic attack.The results were compared with those from 43 patients with delayed LC.Results All the patients were operated by experienced surgeons.There were no significant differences between the two groups in operation time,postoperative complications,intraoperative blood loss,conversion rates,white blood cell count,percentage of neutrophils and blood amylase before and after the operation (P ＞0.05).Patients who received delayed LC had longer hospital stay [(10.6 ± 1.3) vs (17.1 ± 1.8),P ＜ 0.05].The readmission rate in patients with delayed LC was 30.2％ (13/43),and most admissions occurred within 2 ～4 weeks of hospital discharge.In patients with early LC,one patient developed necrotic pancreatitis and died of septic shock.All the remaining patients were cured.Conclusions It is safe,feasible and necessary to perform LC within 48 h in patients with mild to moderate acute pancreatitis and gallbladder stones.Such patients have a high readmission rate and the best timing of delayed LC is within 2 ～ 4 weeks after discharge from hospital.

AIM: To observe the effect of tranilast on experimental COPD rats in terms of airway remodeling. METHODS: Forty eight SD rats were divided into two groups in random: untreated model group, tranilast-treated group. Another eight rats were selected as control group. The COPD rat model was established by passive smoking and intratracheal instillation of lipopolysaccharide (LPS) and then treated with sterile saline or tranilast (400 mg?kg~ -1 ?d~ -1 ) respectively. Eight rats in each group were killed in 7th, 14th, 28th day after the beginning of proceeding. Bronchoalveolar lavage fluid (BALF) was collected, and the total and differential cells were counted. The distribution and the ratio of type I to type III collagen in the lung tissue were determined using a sirius red polarizing microscopy morphometry method. Lung tissues were observed by hemotoxylin and eosin stain, then the image analysis were made. RESULTS: The total cells and the AM ratio in BALF of tranilast-treated group significantly decreased in comparison with those in model group (P

Objective To study the expressions of MCM5 and Ki67 in cervical intraepithelial neoplasia (CIN) and cervical cancer and their clinical significance. Methods Immunohistochemistry (S-P method) was used to detect the expressions of MCM5 and Ki67 in 50 CIN and 49 cervical cancer. Results The positive expression rate of MCM5 and Ki67 in normal cervical epithelium, CIN Ⅰ-Ⅱ, CIN Ⅲ and cervical cancer were 26.7%, 72.0%, 80.0%, 97.9% and 10.0%, 32.4%, 84.0%, 97.9% respectively. The positive expression rate of MCM5 was significantly different between CIN and cervical cancer (P

Objective To investigate the change of serum resistin levels in patients with obstructive sleep apnea hypopnea syndrome(OSAHS).MethodsPolysomnography(PSG)was performed in 58 patients with OSAHS and in 26 controls without differences in age and BMI.Serum resistin levels were measured by ELISA.Results(1)Serum resistin levels were significantly higher in patients with OSAHS than those in control group.(2)FPG levels were significantly higher in patients with OSAHS than those in control group.(3)TG levels were significantly higher in patients with OSAHS than those in control group.(4)Serum resistin levels were correlated positively with FPG in obesity patients with OSAHS、nonobesity patients with OSAHS and nonbesity controls group.(5)Serum resistin levels were correlated positively with TG in obesity patients with OSAHS、nonobesity patients with OSAHS and nonbesity controls group.(6)Serum resistin levels were correlated positively with BMI in OSAHS.(7)Serum resistin levels were correlated negatively with LSaO2 in OSAHS.(8)Serum resistin levels were correlated positively with AHI in OSAHS.ConclusionDetermination of serum resistin levels may be the predictors of the severity of OSAHS and it also contributes a lot taking measures to prevent and control the OSAHS complication occurrence and reduce the mortality.
