To study the relationship between HLA DRB1*07 and the susceptibility to HBV in the Han nationality in Guangdong Province. 100 chronic HBV carrier individuals, 21 HBV spontaneously cleared individuals and 70 HBV unexposed individuals all of Han nationality in Guangdong Province were entered in this study. The expression of HLA DRB1*07 alleles were detected by polymerase chain reaction sequence specific primer, and IFN ? and IL 4 levels in plasma of HBV chronic carrier individuals were measured by using ELISA kits. The results showed that the positive rate of HLA DRB1*07 in chronic HBV carriers was 30%, which was markedly higher than that in HBV spontaneously cleared individuals(4 76%) and HBV unexposed individuals (8 5%) as well ( P

Pro-prostate-specific antigen (proPSA) is the precursor of PSA and a form of free PSA (fPSA). In recent years, a lot of studies have been done on proPSA, the roles of its related indexes in the diagnosis of prostate cancer, and the value of its clinical application. The correlated indexes of proPSA include proPSA, % pPSA, p2PSA, % p2PSA and prostate health index (PHI). They are more effective than total PSA (tPSA) and fPSA in the diagnosis of prostate cancer, especially % p2PSA and PHI, which may significantly increase our ability to detect and identify PCa and lower the rate of unnecessary biopsies. This article presents an overview on the advances in the studies of proPSA and the application of its related indexes in the diagnosis of prostate cancer.

Healthcare delivery is transforming from hospital-centric episodic care to a more patient-centric comprehensive and continuing care that caters to the changing needs of an ageing population and finite healthcare resources. The transition period during which patients move between healthcare settings is a period of vulnerability that requires well-executed care transitions. The relatively less-developed primary, intermediate and long-term care sector further underlines the importance of good transitional care. This article serves to introduce Family Physicians to the importance of transitional care, its broad concepts and a simple framework to help manage complex patients comprehensively in any Family Medicine practice setting.

The extraction method and structure of exo-polysoccharide from schizophyllum commune by submerged cultivation were studied. Proteins were removed com p letely from the polysoccharide by the sevag method following the isoelectric poi nt precipitation method. The purified schizophyllan was proved to be homogeneou s with molecular weight 4?10 4D by sephadex G-200 column chromatography, PAGE and HPLC. Its monomer was determined by hydrolysis, PC, GC and its structure wa s analyzed by IR, enzymolysis, periodate oxidation, the results showed that schi zophyllan was only composed of glucose and it was the ?-glucan consisting of ?-(1-3) and ?-(1-6) glucosidic linkages.

The MPN method was used to enumerate ammonia-oxidizing bacteria (AOB) in water and sediments of several shallow lakes. The suitable incubation time, medium types and substrate (ammonium sulphate) concentrations were studied. The results showed that, MPN values increased with the incubation time, reaching a stable maximum at some time stages, which was 40 days in all the samples for MSF medium. Among the three media used (XZ-AOB、MSF、SW), MSF give the highest MPN value. In addition, am- monium sulphate concentration in medium was an important factor affecting MPN estimation of AOB. Compared to AOB in lake sediments, AOB in lake water was more sensitive to ammonium sulphate concentration.

The painless needle insertion technique, summarized by Professor WU Lian-zhong during his decades of acupuncture clinical practice is introduced in this article, which is characterized as soft, flexible, fast, plucking and activating antipathogenic qi. The Sancai (three layers) lifting and thrusting manipulation technique is adopted by Professor WU for getting the qi sensation. And features of 10 kinds of needling sensation such as soreness, numbness, heaviness, distension, pain, cold, hot, radiation, jumping and contracture are summarized. Finger force, amplitude, speed and time length are also taken as the basis of reinforcing and reducing manipulations. Moreover, examples are also given to explain the needling technique on some specific points which further embodies Professor WU's unique experiences and understandings on acupuncture.

Objective To explore the safety and effectiveness of transurethral resection of the prostate (TURP) for large benign prostatic hyperplasia.Methods A total of 56 cases of patients with large benign prostatic hyperplasia were analyzed retrospectively.Results The weight of prostate tissue resected with TURP was 60.2 g (48-122 g).The resection rate was 60％,operation time 113.4 min (70-180 min).The lower urinary tract symptoms (LUTS) after TURP was improved significantly.The international prostate symptom scores (IPSS) of 38 cases were decreased from (25.6±1.5) before operation to (6.0± 2.0) after operation.The maximum urine flow rate were increased from (5.0±1.9) ml/s to (18.0±4.5) ml/s.The mean residual urine volume of 22 cases were reduced from 95 ml (40-250 ml) to 10 ml (0-60 ml).Conclusions Skilled TURP technology for large benign prostatic hyperplasia is a safe treatment with good effect and low complications rates.

Objective To learn the current anesthesiologists deployment at the hospital,and to figure out how to measure anesthesiologists deployment.Methods Existing data and expert consultation were used to obtain various indicators,and the current anesthesiologists deployment was analyzed,calculating with the formula the needed number of anesthesiologists.Results Despite the rising demand and resource utilization,anesthesiologists were found in obvious shortage at the hospital.The number of anesthesiologists needed was calculated as 101.4,with a vacancy of 11.4.Conclusion The national health authorities were recommended to revise the standard of anesthesiologists deployment at hospitals.

Anesthesia safety plays an important role in the medical safety of the perioperative.At present the medical institutions in many countries apply crew resource management model for training and assessment in anesthesiology,surgery and emergency.It emphasizes the training of nontechnical skills,called crisis resource management(CRM).This article analyzes the causes of human error incidents and preventive measures and introduces CRM principles in medical principles and anesthesia correlation and applications.CRM helps to foresee the crisis of environment and deal with the crisis source to ensure the safety of patients.

OBJECTIVE:To observe clinical efficacy and safety of edaravone combined with butyl phthalide in the treatment of acute ischemic stroke (AIS). METHODS:258 AIS patients were randomly divided into observation group and control group, with 129 cases in each group. Both groups were given routine treatment as antiplatelet,improving microcirculation,controlling blood pressure,lowering blood glucose,regulating blood lipid,keeping plaque stable,nourishing brain cells. Control group was additionally given Butyl phthalide capsules orally,200 mg,tid. Observation group was additionally given Edaravone injection 30 mg added into Sodium chloride injection 100 ml,ivgtt,bid,on the basis of control group. Both groups continuously received 14 days of treatment. The serum inflammatory factor,miR-222 and neurologic impairment score of 2 groups were observed before treatment,7,14 d after treatment. Clinical efficacies and the occurrence of ADR were compared between 2 groups. RESULTS:There was no statistical significance in the serum inflammatory factor,miR-222 and neurologic impairment score between 2 groups before treatment(P>0.05). The serum inflammatory factor and neurologic impairment score of 2 groups were decreased significant-ly 7,14 d after treatment,while serum levels of miR-222 were increased significantly;the observation group was significantly bet-ter than the control group,with statistical significance(P<0.05). Total effective rate of observation group was 92.2%,which was significantly higher than that of control group (69.8%),with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Edaravone combined with butyl phthalide is effective in the treatment of AIS,and can significantly de-crease serum inflammatory factor level,promote the expression of miR-222 and improve neurologic function with good safety.
