OBJECTIVE To learn the relationship between blood recipients with transfusion transmitted diseases before transfusion volunteer donors.METHODS HBsAg,HCV antibody,HIV antibody and syphilis antibody in recipients and donorst were tested.RESULTS From 11 037,HBsAg was positive in 1019 cases(9.233%),anti-HCV positive in 61 cases(0.553%),anti-HIV was positive in 2 cases(0.018%),and syphilis was positive in 88 cases(0.797%).From 57 794 donors,HBsAg was positive(0.606%) in 350 cases,anti-HCV positive in 163 cases(0.282%),anti-HIV positive in 4 cases(0.007%),and syphilis was positive in 347 cases(0.600%).CONCLUSIONS The positive rates of HBsAg,HCV antibody and syphilis antibody among recipients are higher than that in blood donors.So,it′s reasonably to detect these serum infection markers in recipients before transfusion for the purpose of reducing or eliminating the occurrence of iatrogenal transfusion transmitted infection.

Superficial temporal fascia,which has various names,such as temporal fascia,temporoparietal fascia,epicranial aponeurosis and galeal extension,has been used to define the fascial layers of the temporal region.All these different names reflect an anatomical feature of the related fascia.This region exists superficial temporal vessels,the temporal branch of the facial nerve and the auriculotemporal nerve,so is very important in otoplasty.This paper reviews the progress of superficial temporal fascia application in otoplasty.

Fraction absorbed (Fa) is an important parameter to describe the absorption level of oral drugs, and an important basis for the development and optimization of the formulation process. Because it is easily confused with the concept of absolute bioavailability, it has not received enough attention from the industry. There are many complex factors affecting Fa. There are three time-related factors that directly affect the extent of Fa: the release time, the absorption time, and the residence time. The relationship between these three time-related factors determines the extent of Fa. Generally, we are more concerned about the apparent factors that affect the extent of Fa, including independent variables and covariates; The independent variables include administered dose, route, dosage form, etc. The covariates are divided into internal and external factors, and external factors include food factors, drug interactions, etc. Internal causes include age, sex, disease, etc. This paper analyzes and systematically combs how independent variables and covariates directly or indirectly affect the three time-related factors by affecting the body's physiology and internal environment, thus changing the complex process of Fa. Understanding this theoretical framework can better optimize the independent variables to reduce the impact of covariates on Fa. In addition, this paper also introduces the latest progress of prediction and evaluation of Fa, including the progress of complex dissolution device and the status of software prediction.

Chinese materia medica is mostly taken orally. The permeability of a drug’s biofilm (e.g. cell membrane) reflects its ability of absorption and transportation in the body. It is of guiding significance to evaluate the membrane permeability of the active components of Chinese materia medica by using appropriate drug permeation model, so as to clarify, the oral absorption and transport mechanism of active ingredients, pharmacodynamic substance basis and dosage form design. The evaluation method of oral drug membrane permeability, as well as the application of various methods in Chinese medicine was summarized for reference in this review.

Study on the pharmacodynamic material basis of Chinese materia medica (CMM) is the key and difficult points of CMM research due to its complicated components and synergistic effect of multiple pathways and multiple targets in pharmacological action. Currently, research ideas and research methods of the pharmacodynamic material basis of CMM are being constantly innovated. In this review, research ideas and progress on screening and identification of pharmacodynamic substance of CMM were summarized. It suggested that the research model of interdisciplinarity, multi-dimensional screening and evaluation should be established, in order to provide references for further and comprehensively revealing the mechanism of action of CMM and the law of compatibility, and establishing quality evaluation system of CMM.

OBJECTIVE: To investigate the blocking effect of bergapten on cell cycle in nasopharyngeal carcinoma (NPC) cells. METHODS: The inhibition was tested by CCK-8 assay after the NPC cells (CNE-2 and HONE-1) being exposed to bergapten for 48 h. The bergapten concentrations were as follows: 1, 10 and 100 μmol·L-1. The cell cycle was assayed by PI staining and following flow cytometry analysis, and the CDK4, CDK6, CDK2, Cyclin D1, Cyclin E2, β-catenin, GSK-30 and p-GSK-3p (S9) protein levels were detected by Western blotting. RESULTS: Bergapten was able to significantly inhibit CNE-2 and HONE-1 NPC cancer cell proliferations, and the effect was dose-(CNE-2: r=0.926, P<0.05; HONE-1: r=0.959, P<0.05) and time-dependent (CNE-2: r=0.991, P<0.05; HONE-1: r=0.963, P<0.05). Drug treatment induced a block in the G0/G1 phase and decreased protein levels of CDK4, CDK6, CDK2, Cyclin D1, Cyclin E2 and β-catenin, but the protein levels of GSK-3β and the phosphorylation of p-GSK-3β (S9) didn't change. CONCLUSION: Bergapten can block cells cycle and inhibit NPC cells' proliferations, and those effects might be related to suppressing of cells cycle-related protein and interfering with the wnt/p-catenin signal pathway.

Objective: To set up a multi-components by single maker (QAMS) method for determination of four diterpene lactones in Lianzhi Xiaoyan capsules.
Methods: Shimadzu Shim-pack C₁₈ column（250 mm×4.6 mm,5 μm）was adopted with 35 ℃. Acetonitrile-0.1% phosphoric acid aqueous solution as the mobile phase in gradient mode was used at flow rate of 1.0 mL·min^-1. The detection wavelength was set at 203 nm. Andrographolide was used as reference to calculate the relative correction factors of the other three components.
Results: The linear relationships of four components were good （r≥0.999 9） within their ranges, and their average recoveries were 100.0%-102.8% with RSDs 1.1%-2.2%. The results obtained by QAMS were close to those obtained by external standard method.
Conclusion: This rapid, precise and reproducible method can be used for the quality control of Lianzhi Xiaoyan capsules.

Furthermore, such complaints are under control from the start, and prevented from growing into medical disputes, effectively improving quality of care. Such a cycle can effectively avoid medical complaints, enhance medical safety, and build a harmonious doctor-patient relationship.

Objective To explore the relationship between benign prostatic hyperplasia (BPH)and obesity. Methods The 109 elder men were divided into two groups: BPH group (n=59) and non-BPH group (n= 50). The blood samples were collected for the detections of prostate specific antigen (PSA), triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), insulin,androgen, estrogen, sex hormone binding globulin (SHBG) and dehydroepiandrosterone(DHEA).The anthropometric indexes including height, body weigh, waist circumference (WC), hip circumference (HC), systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), waist-to-height ratio (WHtR) and waist-to-hip ratio (WHR) were measured and calculated. The total prostate volume (TPV) were measured by transabdominal ultrasonography three times at least. Results The morbidity rate of BPH was significantly higher in obesity group and over weight group than in health control group (73.33% and 64.28% vs. 26. 67%, x2 = 13. 991 and 6. 836, both P＜0. 002). So was in central obesity group versus in health control group (71.19% vs.36.00%, x2 =12. 156, P＜0. 001). The waist-height index, waist circumference, body weight, BMI and hip circumference were significantly higher in BPH group than in non-BPH group [(0. 56±0. 05)vs. (0.52±0.06), (93. 6±8.8) cm vs. (87.0± 10. 1) cm; (72.6±9.7) kg vs. (64.5±9.3) kg;(25.7±3.4) kg/m2 vs. (23.1±2.9) kg/m2; (100.2±6.6) cm vs. (95.6±8. 1) cm; t=-3.3, -3. 65, -4.38, -4. 17 and -3.18, respectively, all P＜0.01]. The TPV was higher in obesity groupthan in normal group [ (40.8± 23.5 ) ml vs. (20. 1 ± 6.1 ) ml, t = - 2.82, P＜ 0. 002] and obviously higher in central obesity group than in non-central obesity group [(42.8±25.6)ml vs. (26. 9±11.2)ml, t= -3. 93, P＜0. 001]. The ratio of E2/TT and HOMA-IR were higher in central obesity group [(9. 06±4.36) and (2.81 ±2. 80)] than in non-central obesity group [(7. 38±3. 11) and (1. 55±0.76), t= -2.02 and -4.24, both P＜0. 05]. Inversely, the TT and SHBG were lower in central obesity group than in non-central obesity group [(4.54 ± 1.54) nmol/L vs. (5.20 ± 1.54) nmol/L,(45.8± 17.24) nmol/L vs. (59.6 ± 26.09) nmol/L, t = 2.16 and 2.79, both P＜ 0. 05]. Logistic regression analysis showed that waist circumference was a major factor affecting TPV (x2= 19.52, P=0. 000). The annual growth rate of TPV was significantly higher in obesity group and central obesity group than in health control group [(7. 14±8. 09)ml vs. (1. 49±5.14)ml, (7. 96±13.81)mlvs. (1. 35±5.36)ml, t=-2.19 and -3.28, both P＜0. 05]; The PSAD was significantly lower in central obesity group than in health control group [(0. 048±0. 036) vs. (0. 090±0. 093), t=2.02, P＜0. 05], and lower in obesity group than in health control group [(0. 052 ±0. 039) vs. (0. 091 ±0. 080), t= 3. 13, P＜0. 01]. Conclusions The occurrence of BPH is closely related to obesity,especially central obesity. Its mechanism may be related to sex hormone imbalance and the GH/IGF-1 axis disorders in obese patients.

Objective To investigate the regulation effect of bispectral index (BIS) on the depth of total intravenous anesthesia (TI-VA) by comparing with regulating the depth of anesthesia according to the changes of hemodynamics. Methods 60 ASA Ⅰ～Ⅱ patients undergoing laparoscopic cholecystectomy (LC) were randomly assigned into controlled group (group C) and trial group (group T) ,with 30 patients in each group, according to the rules of regulating the titration of propofol during TIVA. The target of group C was to keep SBP/DBP 100 ～ 140mmHg/60 ～ 89mmHg and that of group T was to keep BIS 40 ～ 60 during anesthesia. The measure indexes included SBP/DBP, HR, BIS, total dosis of Propofol, time to extubate, time to leave operating room and OAA/S (observer's assessment of alert-ness/sedation). After operation, we evaluated whether awareness during surgery happens. Results As compared with group C, there were higher SBP/DBP and BIS in group T after induction of anesthesia, during aeroperitonia, immediately after finishing operation and just before extubating endotracheal catheter, but less dosis of propofol and less time of extubation and leaving operating room in group T. The differences had significance (P <0.01). There were no significant differences in the changes of HR between two groups (P >0.05) and no awareness during surgery happened in both groups. Conclusion TIVA regulated by BIS during LC can decrease the dosis of propofol, accelerate the recovery from anesthesia and avoid extremely deep anesthesia and awareness during surgery.
