OBJECTIVEChinese herbal medicine has been extensively used in the treatment of vascular dementia (VaD), but lacked systematic review on its efficacy and safety. So we conducted a systematic review to assess the efficacy and safety of Chinese herbal medicine in treating VaD.

METHODSCNKI, CBM, PubMed, and Wiley Online Library were retrieved for randomized trials (RCTs) on Chinese herbal medicine treating VaD patients. Randomized parallel control trials by taking Chinese herbal medicine as one treatment method and placebos/cholinesterase inhibitors/Memantine hydrochloride as the control were included. Quality rating and data extraction were performed. RevMan5.2.0 Software was used for meta-analysis. Standardized mean difference (SMD) at 95% confidence interval (CI) was used to indicate effect indicators of results.

RESULTSSeven RCTs met the inclusive criteria. Totally 677 VaD patients were randomly assigned to the treatment group and the control group. Descriptive analyses were performed in inclusive trials. The cognitive function was assessed in all trials. Results showed Mini-Mental state examination (MMSE) score was better in the Chinese herbal medicine group than in the placebo group, but with no significant difference when compared with the donepezil group (P > 0.05). Adverse reactions were mainly manifested as gastrointestinal symptoms such as abdominal pain in the Chinese herbal medicine group. But they occurred more in the donepezil group than in the Chinese herbal medicine group.

CONCLUSIONSThe methodological quality of included trials was poor with less samples. Results of different trials were lack of consistency. Present evidence is not sufficient to prove or disapprove the role of Chinese herbal medicine in improving clinical symptoms and outcome indicators of VaD patients. Their clinical efficacy and safety need to be supported by more higher quality RCTs.

Objective To investigate the clinical efficacy of intraluminal enucleation in transurethrat vapor- ization and electro-reesection of the prostate.Methods A retrospective analysis was reviewed in 62 case of prostatic hypertrophy,which were treated with intraluminal enucleation in vaporization of prostate.All pacients had a sucessful operation.There were 12 case in unipolar vaporization and 50 in plasmakenitic bipolar vaporization.Results Opera- tion time ranged from 50 to 162 minutes,with an average of 76min.Bleeding ranged from 40 to 200 ml,with an av- erage of 110ml.There was no blood transfusion.The weight of prostate was 62～138g,the catheter was maintained for 3～5 days postoperatively.The hospital stay was 7～10 days,average 8 days.All patients were cured.There was a fllow-up for 1～20 months,with an average of 8 months.The IPSS decreased by 22 points on average,and peak urine flow(Qmax)increasd to(16.8?3.3)ml/s.There wre no urethralstricture,permanent urinary incontinence, TURS,postoperative hemorrhage,retrograde ejaculation and recurrence.Conclusions Intraluminal enucleation in treatment of prostalic hypertroply is a new,safe,and effective method,which should be popularized in clinical prac- tice.

Objective To explore the relationships of serum leptin(LP),tumor necrosis factor-?(TNF-?)and insulin resistance in simple obesity children.Methods Forty-seven children with simple obesity were divided into two groups: high insulin group(HIG) and normal insulin group(NIG) according to the levels of fasting state of serum insulin and glucose.The fasting state of serum insulin(FINS),LP,TNF-? and fasting blood glucose(FBG) were measured.The relationships of LP,TNF-? and insulin resistance index(HOMA-IR) were also analyzed.Results 1.The BMI,waist,hip,waist hip ratio(WHR),LP,TNF-?,HOMA-IR were obviously higher in the HIG than those in the NIG and NCG groups(Pa0.05).3.In the HIG group,the FINS was positively correlated to LP,TNF-? and HOMA-IR(r=0.560,0.413,0.864 P

OBJECTIVETo investigate the significance of human papillomavirus test in triage of patients with atypical squamous cell of undetermined significance (ASCUS) diagnosed by cervical cytology.

METHODSHuman papillomavirus test,colposcope and cervical biopsy were performed in 184 patients with a referral diagnosis of ASCUS by cervical cytology.

RESULTSConfirmed by pathological diagnosis of cervical biopsy, 112 cases were chronic inflammation (60.87%), 33 CIN I (17.93%), 17 CIN II (9.24%), 8 CIN III (4.35%), 4 cervical squamous carcinoma (2.17%) and 10 condyloma (5.43%). Of the 184 women with cytological ASCUS, 124 (67.39%) cases were positive in high-risk HPV test among which 66 cases were histologically confirmed as chronic inflammation (53.23%), 22 as CIN I (17.74%), 16 as CIN II (12.90%), 8 as CIN III (6.45%), 4 as cervical squamous carcinoma (3.23%) and 8 as condyloma (6.45%). The positive rate of HPV in groups of ASCUS were higher than those with negative HPV (P < 0.003).

CONCLUSIONWomen with ASCUS should be tested for HPV. Cervical biopsy under colposcopy is recommended for women with HR-HPV infection.

OBJECTIVETo promote its comprehensive utilization, the involatile constituents of Mentha haplocalyx were studied systematically.

METHODThe chemical components were isolated and purified by silca gel column chromatography and recrystallization. The chemical structures were elucidated on the basis of physico-chemical properties and spectral data.

RESULTEight compounds were isolated and identified as: acacetin (I), tilianine (II), linarin (III), n-butyl-beta-D-fructopyranoside (IV), ursolic acid (V), oleanolic acid (VI), beta-sitosterol (VII), daucosterol (VIII).

CONCLUSIONCompounds I approximately V were obtained from this plant for the first time.

OBJECTIVETo investigate the clinic value of combination of high-risk human papillomavirus test and cervical cytology test in diagnosis of cervical lesions.

METHODSPatients underwent physical examination at our department were checked by high-risk human papillomavirus test, cervical cytology test and colposcope from October 2004 to December 2006. Abnormal patients with cervical abnormalities were asked for pathological test.The diagnostic value of cervical lesions among these different methods were compared.

RESULTSBased on the criteria of histopathology, the sensitivity, specificity, positive-predictive value and negative-predictive value of high-risk human papillomavirus test for detecting all cases of CIN II and CIN III were 94.83%, 31.06%, 55.22% and 87.02% respectively, and those of the cervical cytology were 92.10%, 31.06%, 54.50% and 81.43% respectively.Those values changed to 99.65%, 18.55%, 61.46% and 97.62% respectively if two methods were combined.

CONCLUSIONSHuman papillomavirus test and cervical cytology test combined with pathological test can improve the detective rate of cervical lesions and facilitate the treatment.

In this study, the "150-cavity", next to the H5N1 influenza virus neuraminidase activity site, has been used as the target to design and synthesize a structural analogue of chlorogenic acid, N-caffeoyl-GABA, using the flexible docking simulation. The docking study showed that the N-caffeoyl-GABA could be inserted into the "150-cavity" and combined with the Arg156 side chain by hydrogen bond. The best binding free energy of H5N1 NA-N-caffeoyl-GABA complex was -7.70 kcal mol(-1), equivalent that of the NA-oseltamivir. At the same time, using the H5N1 pseudotyping virus-based NA inhibitors screening model, we determined the inhibitory effect of oseltamivir, chlorogenic acid and N-caffeoyl-GABA on the NA. Compared with chlorogenic acid, N-caffeoyl-GABA significantly enhanced the inhibitory effect on NA, but less than oseltamivir. This study showed that the "150-cavity" could possibly be used as a new neuraminidase inhibitors target, and provided a path for the development of new neuraminidase inhibitors.

OBJECTIVETo explore the prevalence of coronary artery disease and risk factors in patients with abdominal aortic aneurysm (AAA).

METHODSCoronary angiography was performed immediately after abdominal angiography in 70 elderly (> 50 years) consecutive patients with AAA. Medical history and imaging characteristics were evaluated.

RESULTSCAD was diagnosed in 63 patients (90.0%) by coronary angiography: 20 (28.6%) patients with single-vessel disease (SVD), 15(21.4%) with 2VD, 22 (31.4%) with 3VD and 6 (8.6%) with left main disease + 3VD. Multi-variance logistic analysis showed that peripheral disease was the strongest predictor for CAD in AAA patients.

CONCLUSIONCoronary angiography should be performed in elderly AAA patients due to the high prevalence of CAD in this patient cohort.
