To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

OBJECTIVETo research the co-infections of HIV and human herpesvirus 8 (HHV8) in Uygur high-risk groups of HIV infection in a city Xinjiang.

METHODSAll 468 Uygurs at high HIV risk registered in the sentinel monitoring system in 2006 were enrolled in this study. The antibodies to HHV8 latency-associated nuclear antigens 1 (LANA1), lytic antigens open reading frame 65 (ORF65) and K8.1 were measured by enzyme linked immunosorbent assay (ELISA). Chi-square test and non-condition Logistic regression model were used for data analysis.

RESULTSOf 468 sera samples, 67 (14.3%) were HIV and HHV8 co-infection positive.Male's HIV and HHV8 co-infection rate (22.6%, 54/239) was higher than the female's (5.7%, 13/229) (chi(2) = 27.285, P < 0.001). For those above 24 year old, HIV and HHV8 co-infection rate (15.8%, 65/412) was higher than the < 24 year old group's (3.6%, 2/56) (chi(2) = 5.987, P = 0.014). The group of Elementary school and illiterate people's HIV and HHV8 co-infection rate (20.7%, 40/193) was higher than the junior middle school and the above culture (9.8%, 27/275) (chi(2) = 10.999, P = 0.001). For the unmarried people, the co-infecting rate of HIV and HHV8 for the married, the cohabitants, the divorced or the widowers were 16.9% (14/83), 12.2% (42/345), 27.5% (11/40) respectively. There was significantly statistical difference among three marital status (chi(2) = 7.399, P = 0.025). Injecting drug users' HIV and HHV8 co-infection rate (26.5%, 50/189) was higher than non-injecting drug users' (6.1%, 17/279) (chi(2) = 38.083, P < 0.001), and stratified by gender, OR(M-H) was 4.207 (95%CI: 1.529 - 11.578). Via non-condition logistic stepwise regression analysis, only injecting drug use entered model, compared with non-injecting drug users, injecting drug users were more dangerous for HIV and HHV8 co-infecting (OR = 5.544; 95%CI: 3.081 - 9.975).

CONCLUSIONThe HIV and HHV8 co-infection rate was higher in the Uygurs at high HIV risk in Xinjiang. Injecting drug use is a risk factor of the HIV and HHV8 co-infection, which might be one of routes of HIV and HHV8 co-infection among this group.

OBJECTIVETo analyze the clinical and laboratory features of anti-soluble liver antigen/liver-pancreas (SLA/LP) autoantibody positive patients with abnormal liver functions.

METHODSFrom July 1999 to August 2004, 4928 serum samples from patients with abnormal liver functions (ALT >40 U/L) were collected. A series of autoantibody examinations were carried out. Clinical manifestations and laboratory findings of 8 patients with anti-SLA/LP autoantibody positive were reviewed.

RESULTSAmong the 5500 serum samples, 8 cases (6 females and 2 males) with positive anti-SLA/LP autoantibodies were found with complete clinical information. The age of the patients was (27-76) years old. The case histories were from 2 years to 10 years. Of the 8 patients, 6 cases had liver cirrhosis and HBsAg-negative and anti-HCV-negative, active, 1 case had liver cirrhosis with HBsAg-positive, but HBVDNA negative; 1 case had liver cirrhosis and anti-HCV positive, but HCV RNA negative. The 8 cases were all ANA positive with titers of 31:320. Four cases were AMA positive and 2 among these 4 cases were M2 positive. The most frequent symptoms were fatigue, anorexia, nausea, jaundice, abdominal distention and edema of lower limbs. All patients had high hypergammaglobulinemia.

CONCLUSIONAnti-SLA/LP autoantibody was at a low detection rate in the study with females in preponderance, Clinical and laboratory characteristics of the 8 cases were consistent with those of the autoimmune hepatitis (AIH). Testing for anti-SLA autoantibodies helps in the diagnosis of AIH in many patients who may otherwise be misdiagnosed.

OBJECTIVETo investigate the effect of flurbiprofen preemptive analgesia combined with intravenous propofol anesthesia in induced abortion.

METHODSTotally 175 women (ASA class I) undergoing induced abortion were randomized into 5 groups. In K10, K5, and K1 groups, the patients were given 50 mg flurbiprofen 10, 5 and 1 min before the operation, respectively, and in F group, 1 microg/kg of fentanyl was administered 10 min before the operation. All the 4 groups had intravenous induction with 2 mg/kg propofo1. The patients in P group received propofol at 2 mg/kg as the control group. The heart rate (HR), mean arterial pressure (MAP) and SpO2 were monitored during the operation, and the induction time, recovery time, propofol dosage and adverse effect were recorded. The anesthetic effect of the protocols was assessed according to the visual analogue scale (VAS) and the overall patient satisfaction.

RESULTSHR, MAP, propofol consumption and the incidences of adverse effects during the operation were significantly higher in P group than in the other groups. F group had the highest incidence of respiratory depression among the 5 groups. The VAS in K10 group was significantly lower than that in K5 and K1 groups (P<0.05), but similar to that in F group (P>0.05). The overall patients' satisfaction was significantly higher than that in the other 4 groups.

CONCLUSIONFlurbiprofen preemptive analgesia combined with intravenous propofol is safe and effective for anesthesia during induced abortion.

OBJECTIVETo evaluate the effect of epidural anesthesia and patient-controlled epidural analgesia (PCEA) on hemorheology and the incidence of deep venous thrombosis in patients undergoing gynecological laparoscopy.

METHODSOne hundred ASA I-II patients undergoing gynecological laparoscopy were randomly allocated into 2 groups to receive general-epidural anesthesia combined with PCEA (GE group) and general anesthesia (G group). Blood samples were taken before anesthesia (T(0)), before operation (T(1)), 30 min after pneumoperitoneum (T(2)), 30 min after pneumoperitoneum cease (T(3)), and 24 and 48 h after the operation (T(4), T(5)) for hemorheological tests.

RESULTSIn GE group, the blood viscosity, plasma viscosity and RBC aggregation decreased significantly at T(1) (P<0.05), but no significant variations were detected at the other time points. In G group, blood viscosity and plasma viscosity increased significantly from T(2) to T(5), and were significantly higher than those of GE group. The incidence of deep venous thrombosis of GE group (2%) was significantly lower than that of the G group (8%).

CONCLUSIONThe blood viscosity, plasma viscosity and RBC aggregation increase during gynecological laparoscopy, and can be reduced by epidural anesthesia and PCEA to lower the incidence of deep venous thrombosis.

Objective To investigate the basic distribution of endemic areas in the type of drinking water arsenism and in Xiantao City,Hubei Province,and to offer a scientific basis for control and prevention.Methods According to"the Chinese Scheme of Implementing Surveillance of Distribution of Endemic Arsenism",considering with the special geography feature of Xiantao,both sampling and overall survey were used in 7 towns chosen.The water arsenic content was determined by half quantitative fast reagent-box method.We began to search for clues and patients according to the endemic areas and the families with high arsenic wells.Results High endemic arsenic water sources were distributed in 7 the towns(districts or farms).In 81 villages of Xiantao City,35 villages had drinking water arsenic content exceeding 0.05 mg/L,accounting for 43.21%(35/81).In 4020 screened wells,269 had arsenic content higher than the national standard,the detective rate of high arsenic wells(more than 0.05 mg/L)was 6.69%(269/4020),with the highest rate in Shahu Seed Plant being 13.56%(115/848).The population exposed to high arsenic was 1091,in a rate of 5.75%(1091/18 975),in which 281 children were exposed in a rate of 5.82%(281/4826).In Shahu Seed Plant,467 people including 129 children were exposed to high arsenic, accounting for 13.26%(467/3522)and 12.91%(129/999),respectively.Conclusions High arsenic sources widely exist in Xiantao City,especially in Shahu Seed Plant,where arsenic content,the exposed rate of population and children are high.Therefore,prevention and control should be carried out in the southeast as soon as possible,as well as in other places where situation is less serious.

Binocular vision refers to a progress of analysing and integrating the binocular visual signals into a whole and three-dimensional sensory perception by higher nerve centre. In this process, the interac-tion between the two eyes results in the changes of output signal, which is called binocular interaction. Through a series of subjective and objective experiments, it can be concluded that binocular interaction can be divided into three types: facilitation, summation and suppression, and the forms of binocular in-teraction in different visual states are different. In general, the visual signal is processed by binocular in-teraction, so that there are some differences between binocular vision and monocular vision. The extent of the difference can be affected by the damage of monocular vision and then affects the binocular vision. Thus, it is necessary for forensic scientists to further study the effects of the monocular visual impairment on visual function. Based on relevant data, this paper reviews the mechanism of the monocular visual impairment in binocular vision, the research methods and the application prospect in forensic science.
