OBJECTIVETo observe the difference effects between warming-promotion acupuncture and normal acupuncture on lumbar spinal stenosis (LSS).

METHODSSixty cases of LSS were randomly divided into a normal acupuncture group (30 cases) and a warming-promotion acupuncture group (30 cases). The two groups both chose Dazhui (GV 14), Mingmen (GV 4), Jiaji (EX-B 2),etc. Normal method without special manipulation was used in normal acupuncture group, while the warming-promotion manipulation was used in warming-promotion acupuncture group, all once daily, 10 treatments made one session. Compare the symptoms and spinal cord function of LSS, quality of life (QOL)and clinical effect in the two groups.

RESULTSThe comprehensive score of symptoms of LSS in warming-promotion group 3 months after treatment was 6.30 +/- 1.92, while that in normal acupuncture group was 4.67 +/- 13.70. The score of spinal cord function in warming-promotion group after treatment was 7.03 +/- 1.03, while that in normal acupuncture group was 6.33 +/- 1.12. The score of QOL in warming-promotion group after treatment was 53.67 +/- 8.91, while that in normal acupuncture group was 64.50 +/- 16.69. All the differences between these scores in two groups were statistically significant (all P < 0.05). The total effective rate was 90.0% (27/30)in warming-promotion group, and 80.0% (24/30) in normal acupuncture group. The effect of warming-promotion group was better than that in normal acupuncture group (P < 0.05).

CONCLUSIONIn the field of treating LSS, the effect of warming-promotion acupuncture is better than normal acupuncture.

To discover novel antitumor rhodanine unsaturated ketones, a series of fluoroquinolone (rhodanine α, β-unsaturated ketone) amine derivatives (5a-5r) were designed and synthesized with fluoroquinolone amide scaffold as a carrier. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS. The in vitro anti-proliferative activity against Hep-3B, Capan-1 and HL60 cells was evaluated by MTT assay. The results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. The SAR revealed that some compounds carrying aromatic heterocyclic rings or phenyl attached to an electron-withdrawing carboxyl or sulfonamide substituent were comparable to or better than comparison doxorubicin against Capan-1 cells. As such, it suggests that fluoroquinolone (rhodanine α, β-unsaturated ketone) amines are promising leads for the development of novel antitumor fluoroquinolones or rhodanine analogues.

To discover an efficient strategy for the conversion of the antibacterial activity of fluoroquinolones into the antitumor activity, the three series of C-3 s-triazole-based derivatives including sulfide ketones (6a-6g), thiosemicarbazones (7a-7g) and fused heterocyclic thiazolotriazoles (8a-8g) were synthesized from ciprofloxacin (1), respectively. The structures were characterized by elemental analysis and spectral data. The antitumor activity was tested against three tumor cell lines (Hep-3B, Capan-1 and HL60) using the MTT assay. The three types of compounds all exhibited stronger anti-proliferative activities than ciprofloxacin in the test. The order of their activities was in compounds 7>8>6, and the order of selectivity against cancer cell lines was Capan-1, Hep-3B and HL60. Meanwhile, the SAR revealed that some compounds with electron-drawing group substituted such as fluoro- and nitro-phenyl compounds (6f, 7f, 8f) and (6g, 7g, 8g) displayed more significant activity than the control compounds, especially the IC50 values of thiosemicarbazone compounds 7f and 7g against Capan-1 was comparable to doxorubicin. Thus, a five-membered triazole as the C-3 bioisostere modified with the functionalized side-chain of sulfide-ketone thiosemicarbazone warrants special attention and further investigation.

To discover novel antitumor fluoroquinolone lead compounds from a rational modification for antibacterial fluoroquinolones, a fused heterocyclic ketone corresponding to thiazolo[2,3- b][1,2,4]triazolone used as a bioisosteric replacement of the C-3 carboxylic acid group of ciprofloxacin 1, and further modification by a Claisen condensation reaction with substituted benzaldehydes formed novel fluoroquinolone C-3 fuse heterocyclic α, β-unsaturated ketones as the title compounds (6a-6r), separately. The structures of eighteen title compounds were characterized by elemental analysis, 1H NMR and MS, and the in vitro anti-proliferative activity against human hepatoma Hep-3B cells, pancreatic Capan-1 cells and leukemia HL60 cells was evaluated by a MTT assay. The preliminary results showed that the title compounds not only had more significant anti-proliferative activity against three tested cancer cell lines than that of the parent ciprofloxacin 1, but also exhibited the highest activity against Capan-1 cells. In particular, compounds carrying an electron-withdrawing carboxyl (6k, 6m) or sulfonamide substituent (6q, 6r) attached to benzene ring were comparable to or better than constractive drug doxorubicin against Capan-1 cells. As such, it suggests that it is favorable for a fused heterocyclic α, β-unsaturated ketone scaffold instead of the C-3 carboxylic acid group to improve the antitumor activity of fluoroquinolones.

OBJECTIVEBy measuring airflow and ventilation distribution of ward building, to explore and verify the hypothesis of airborne transmission and risk factor of severe acute respiratory syndrome (SARS) nosocomial infection.

METHODSTracer gas (perfume of plant oil) was emitted to the bathroom of wards when SARS index patient lived. Six different experimental situations were designed to control the status of exhaust fan in bathrooms, exhaust fan in the top of building and fresh air exchange system. The concentration of perfume was separately measured by 4 groups of lab workers and recorded blindly by the scores of "tenth degree".

RESULTSTracer gas was detected from the wards of 8th to 13th floor.

CONCLUSIONArchitecture and ventilation system of the inpatient building in the hospital contributed to the aerodynamic condition of SARS nosocomial infection through airborne transmission. The distribution of tracer gas in the wards was associated with SARS patients in this building. It was possible that SARS could have been transmitted to for distance by aerosol or other carriers.

OBJECTIVETo evaluate the effect on pre-exposure prophylaxis (PrEP) to prevent HIV infection in high risk populations.

METHODSA computerized literature searching had been carried out in PubMed, EMbase, Ovid, Web of Science, Science Direct, Wanfang, Tsinghua Tongfang database and related websites to collect relevant papers (from establishment to June 2012) with the key words of pre-exposure prophylaxis, HIV, AIDS, high risk populations, relative risk, reduction. All randomized controlled trials (RCT) papers about using single or compound antiretroviral drugs (ARVs) orally or topically before HIV exposure or during HIV exposure in high risk populations were enrolled. Meta-analysis was conducted using Stata 10.0 to calculate the pooled RR value (95%CI). Consistency test was performed and publication bias was evaluated.

RESULTSFinally 5 RCT papers were enrolled, including 10 271 persons who were at high risk of HIV infection. The number of the experimental group was 5929, among which 116(1.96%) became infected. The number of the control group was 4342, among which 201(4.63%) became infected. Meta-analysis showed that the pooled relative risk (RR) and 95%CI was 0.49 (0.39 - 0.61), P < 0.05, indicating that the persons in experimental group had a 0.49 times lower risk of HIV infected, as compared with the control group. Publication bias analysis revealed a symmetry funnel plot. The fail-safe number was 825.

CONCLUSIONPrEP was an effective and safe protection measure to reduce HIV infection in high risk populations.

Objective To study the use of preoperative indocyanine green retention test at 15 minutes (ICG R15) in the prediction of liver functional reserve in patients with hilar cholangiocarcinoma (HCCA).Methods The clinical data of 62 patients with HCCA treated in our department from March 2016 to March 2018 was reviewed.The relationship between preoperative ICG R15 and postoperative hepatic insufficiency was analyzed.The relationship between preoperative ICG R15 and Child-Pugh scoring was also studied.Univariate analysis was used to evaluate the risk factors of postoperative liver dysfunction.Logistic regression was used to assess the independent risk factors of postoperative liver dysfunction.The regression equation between independent risk factors and postoperative liver dysfunction was established.Results Among the 62 patients,ICG R15 was less than 10.0％ in 26 patients,between 10.0％ and 19.0％ in 17 patients,between 20.0％ and 29.0％ in 9 patients,between 30.0％ and 39.0％ in 5 patients,and over 40.0％ in 5 patients.There were 29 patients with a Child-Pugh A grading and 33 patients with a Child-Pugh B grading in the preoperative evaluation of liver function.The Wilcoxon W rank sum test was used to compare the preoperative ICG R15 in patients with Child-Pugh grading A and B separately.The ICG R15 in Child-Pugh grading A patients was significantly lower than those in Child-Pugh B grading patients (P ＜0.05).There were no significant differences in age,gender,history of previous liver diseases,duration of operation,and intraoperative blood loss (P ＞ 0.05) between the normal liver function group and the liver dysfunction group.However,there was a significant difference in the preoperative ICG R15 and preoperative bilirubin levels (P ＜ 0.05) between the two groups.The preoperative ICG R15 and preoperative bilirubin levels were significant risk factors of postoperative hepatic insufficiency.Regression analysis suggested that preoperative ICG R15 level was an independent risk factor of postoperative hepatic insufficiency (P ＜ 0.05).A regression equation:logit(P) =0.185 × preoperative ICG R15-3.152 could be constructed.Conclusions ICG R15 is an ideal clinical indicator for evaluation of preoperative liver functional reserve in patients with HCCA.It predicted the recovery of postoperative liver function.

Objective To study the acceptability of pre-exposure prophylaxis (PrEP) to prevent the transmission of HIV among men who have sex with men (MSM) in Guangxi, China.Methods Snow-balling methods were used to recruit 650 MSM in Guangxi. Questionnaires and interview were administrated to these 650 men, using a self-designed questionnaire and face to face interviews to collect information on HIV-related risk behaviors, knowledge and acceptability of PrEP.effective, safe and free of charge', 597 (91.9%) of the 650 MSM claimed that they would accept it,who refused to use it, most of them said that were afraid of the side-effect and doubted on the effectiveness of PrEP. Data from logistic regression analysis showed that those who had found partners through friends (OR=6.21, P=0.020) and those who would advise his friend to use PrEP (OR=39.32, P=0.000) were more likely to accept PrEP. Those who thought they could protect themselves from HIV infection (OR=0.32, P=0.010) or not having sex with the ones who refused to use a condom (OR=0.34, P=0.010) were less likely to accept PrEP. Conclusion Effectiveness, safety and cost seemed to be the main influential factors related to the acceptability of PrEP. Peer education might improve the acceptability of PrEP.

Objectives:This study aimed to evaluate the predictive value of the CHA 2DS 2-VASc score for in-hospital outcomes of patients with acute myocardial infarction (AMI). Methods:Data of 23 728 patients from the China patient-centered Evaluative Assessment of cardiac Events (China PEACE)Retrospective Acute Myocardial Infarction Study were analyzed retrospectively. The patients were categorized into 3 groups according to the CHA 2DS 2-VASc scores: the low score group (score 1-3), the middle score group (score 4-6) and the high score group (score 7-9). The in-hospital outcomes included major adverse cardiovascular events (MACE), death, death or withdrawal from treatment, reinfarction, ischemic stroke,etc. The CHA 2DS 2-VASc score was incorporated into multivariate Cox regression analyses to determine its independent impact on in-hospital outcomes. Receiver operating Characteristic (ROC) curves were constructed, and the area under the curve (AUC) was used to evaluate the predictive value of the CHA 2DS 2-VASc score for in-hospital mortality and death or withdrawal from treatment, respectively. Results:The patients had a median age of 66 (56,75) years, and 30.7% of them were females. Patients with higher CHA 2DS 2-VASc scores had a higher in-hospital mortality and more in-hospital complications (all P<0.001). After adjustment of baseline covariates, the subjects in the high score group were associated with high risks of in-hospital mortality ( OR=6.13, 95% CI 4.77-7.87, P<0.001), death or treatment withdrawal ( OR=6.43, 95% CI 5.16-8.00, P<0.001) and MACE ( OR=4.94, 95% CI 4.06-6.01, P<0.001). The AUCs of the CHA 2DS 2-VASc score were comparable with those of the mini-global registry of acute coronary events(mini-GRACE)score in evaluation of in-hospital mortality (0.699 vs. 0.696, P=0.752) and the death or treatment withdrawal risk (0.708 vs. 0.713, P=0.489). Conclusions:The CHA 2DS 2-VASc score is an independent predictor of in-hospital outcomes for patients with AMI. Its predictive value was comparable with the mini-GRACE score, which could be used as a simple tool for early and rapid outcome evaluation for AMI patients.
