Objective:To detect the anti-cancer component, trans-resveratrol in red wine by high performance liquid chromatography, and to determine the influence of environmental factors on its content. Methods: A method for determining trans-resveratrol in red wine by HPLC is described. The operating conditions were ZORBAX-C18 column(4.6 mm×250 mm, 5μm) at room temperature, 30%acetonitrile as mobile phase at a flow of 1ml/min and UV detection at 306 nm. Results:The content of trans-resveratrol in Changyu dry red wine and Great Wall Claret Cabernet are (1.01±0.03)mg/L and (2.36±0.02)mg/L, respectively. The results show that, sunlight, high temperature and poor seal condition can decrease the content of trans-resveratrol. Conclusion:The content of trans-resveratrol varies in different brands of red wine. Red wine should be stored in cool, dark and sealed conditions.

Asthma is one kind of chronic respiratory tract inflammatory disease.Recently,it has been discovered that the small airway also participates in asthmatic pathogenesis.The small airway which diameter is less than 2 mm is one of the smallest regions in the lung.Its function may be affected by the small airway disease and related with the airway hyperresponsiveness.Some structural changes in the small airway is the latent reason which aggravates asthma.The change of small airway function in the mild asthma can cause the change of airway hyperresponsiveness.So it is considered that the small airway function is one of the methods to monitor the asthmatic situation.

BACKGROUND: Embryonic pancreatic tissue is characterized by its abundance, potent in proliferation & differentiation, and minimal immunological rejection. It is widely considered as potential pancreatic endocrinological stem cells resource for treating diabetes mellitus.OBJECTIVE: To investigate the embryonic mouse pancreatic tissue isolation technique and observe the recipients' blood glucose regulatory effects of the grafted embryonic pancreas in an experimental diabetes mellitus mouse model.METHODS: Pancreatic tissue from C57B1/6 mouse embryos at embryonic days 11.5-16.5 was isolated under the stereomicroscope. C57BL/6 mouse models of streptozocin-induced diabetes mellitus were established and then randomly divided into two groups: transplantation group, in which, five pieces of pancreatic tissue of mice at embryonic 16.5 days were transplanted into mouse renal capsule, and sham-operated control group, in which, 0.05 mL RPMI1640 culture medium was injected into mouse renal capsule. When blood glucose level of the transplantation group mouse was≤ 11.2 mmol/L, the endocrine function of embryonic pancreatic tissue transplanted was detected by IPGTT and IPITT methods and then the transplanted graft was removed for observing the blood glucose relapse.RESULTS AND CONCLUSION: Nearly intact pancreatic tissue of mice at embryonic days 11.5-16.5 could be isolated through the use of stereomicroscope. Pancreatic tissue morphology and color of mice ≤ embryonic 12.5 days were difficultly distinguished from adjacent tissue and they could only be isolated carefully according to the relationship with adjacent organs. Pancreatic tissue of mice > embryonic 12.5 days exhibited initial endocrinological tissue morphology mimic white cauliflower. Histological and ELISA examinations showed that embryonic pancreatic tissue could express and secrete insulin and the insulin level was gradually increased with developmental time. Embryonic pancreatic tissue could grow beneath the recipient renal capsule. The insulin and glucagon expression in the post-transplantational pancreatic tissue graft was increased compared with prior to transplantation. These results suggest that pancreatic tissue is a potential stem cell resource for treating the diabetes mellitus.

OBJECTIVETo explore the therapeutic effect of diagnosis and treatment program of integrative medicine (IM) on level 2 hypertension in the young and middle-aged patients and their ambulatory blood pressure.

METHODSA randomized, placebo parallel and controlled, multi-center clinical trial was performed. Totally 199 young and middle-aged level 2 hypertension patients were randomly assigned to the treatment group (99 cases) and the control group (100 cases). All received combined hypotensive treatment program by taking Nifedipine Sustained Release Tablet and Hydrochlorothiazide as basic drugs. Patients in the treatment group additionally took Western medicine (WM) combined Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily), while those in the control group additionally took WM combined simulative agents of Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily). The treatment course was 8 weeks for all, and 24-week follow-ups performed. 24 h ambulatory blood pressure and casual blood pressure, and their efficacies were compared between the two groups, and safety assessed as well.

RESULTSCompared with before treatment in the same group, daytime and night casual blood pressure, as well as 24 h ambulatory blood pressure were all obviously improved in the two groups (P < 0.01). Average diastolic and systolic blood pressures at night decreased more in the treatment group than in the control group with statistical difference (P < 0.05). There was no statistical difference in total efficacies of daytime casual blood pressure or ambulatory blood pressure (P > 0.05).

CONCLUSIONJiangyabao serial drugs combined WM in treating young and middle-aged level 2 hypertension patients showed obvious effect in improving night blood pressure, especially for night diastolic blood pressure.

In recent years the interaction between host and gut microbiota has attracted increasing attention. However, intestinal flora dysbiosis may lead to many diseases, and there is increasing evidence that the intestinal microbiota in patients with chronic kidney disease (CKD) is associated with the pathophysiological status of the host. "Gut-kidney axis" provides a better explanation of the two-way communication between intestinal flora and CKD. Impaired kidney function leads to dysbiosis of intestinal flora and an altered intestinal flora can damage the intestinal mucosal barrier and facilitate the entry into the bloodstream of harmful bacteria, which can induce chronic inflammation and thus accelerate renal injury. In addition, the accumulation of nephrotoxic metabolites from an altered intestinal flora can aggravate CKD in the "gut-kidney axis". Among them, p-cresol sulfate, indoxyl sulfate and trimethylamine oxide are the most widely studied metabolites of nephrotoxicity, and their renal toxicity has been widely confirmed in basic research and clinical studies. Current studies show that the intestinal microbiota-metabolite network is closely related to the occurrence and development of chronic kidney disease. Thus, intervention in the intestinal microbiota may provide a new approach to the prevention and treatment of chronic kidney disease.

Objective To investigate clinical significance of computed tomography (CT) scan in diagnosis of bronchial foreign body in children.Methods Twenty-one suspected children with bronchial foreign body were studied with spiral CT cross-section scan and coronal reconstruction and diagnosis was confirmed with bronchoscopy.Results The foreign body was displayed in all of 21 cases. CT scan showed foreign body was located in right main bronchial 12 cases, right middle bronchial 1 case, right inferior lobar bronchial 2 cases and left main bronchial 6 cases. Foreign bodies were extracted with bronchoscopy.Conclusion CT scan can display and locate accurately foreign body in bronchial of children,and has very important diagnostic value in patients having atypical histories, clinical and radiological findings.

Objective To introduce the therapeutic measure of preventing the first web contracture after hand crush injury in early stage. Methods Three types were divided according to the traumatic condition in 57 cases: closed injury, open injury and with blood vessel of thumb or fingers injury, and used different method such as closing injury postpone, opening the first web by kischner wire or mini-external fixation splint and covered by local or island flap to cure each type in primary and early stage, after 6 months, measured the width and angle of the first web. Results Forty-one cases were followed-up after 3 months - 2 years,abduction and opposition of the thumbs were fine, the average of width and angle of the first web were (5.89 ± 0.58)cm and (87.85 ± 6.03)°. Conclusion The key points of preventing the first web contracture after crush injury are opening the first web that being covered by local flap and to use splint in primary stage.
