Objective To study the effects of lifestyle quantilization based-weight management on overweight or obesity police officers.Methods One hundred and seven overweight or obesity police officers received lifestyle quantilization based-weight management (i.e.Jinbi weight management) and were then assigned to the excellent performance group (group A,n =50),good performance group (group B,n =42)and loss to follow-up group (group C,n =15).Dietary habits,body weight,height,waist circumference (WC),blood pressure (BP),total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C) and fasting plasma glucose (FPG) were measured before and after the intervention.After 8 weeks' intervention,the changes of above parameters were recored.Student's t test was used for data analysis.Results Of group A and B,83 reported weight loss (group A t =13.31,group B t =5.04 ; both P ＜ 0.05).In group A,body weight,body mass index (BMI),WC,body fat and visceral fat index were significantly decreased,in contrast to body water (t values were 13.31,13.72,10.8,8.59,6.83 and-6.62,respectively; all P ＜ 0.05).However,there were no significant changes of BP,FPG,TC,TG,LDL-C and HDL-C in group A.Following intervention,daily dietary energy intake of group A was reduced by 74.1 k J,fat intake was decreased by 11.6 g,energy ratio of dietary fat was decreased by 1.8％,energy ratio of cereal was increased by 4.2％,and sodium chloride and cooking oil was decreased by 1.3 g and 10 g,respectively.Conclusion Lifestyle quantilization based-weight management shows effectiveness among overweight or obese police officers,and thus may be recommended for other functional communities.

Objective:To explorethe the clinical manifestations, treatment and prognosis of anastomotic pseudoaneurysm after renal transplantation caused by infection.Methods:Clinical data of 1 recipient with pseudoaneurysm after renal transplantation due to Pseudomonas aeruginosa infection were retrospectively analysed and combined with a literature review. Results:At Month 2 post-transplantation, the recipient developed right lower abdominal pain, and contrast-enhanced ultrasound examination showed a pseudoaneurysm at the artery anastomosis. Anti-infection and anti-rejection therapy had no obvious effect, and therefore next surgical exploration was performed. A size4.0 cm×3.5cm pseudoaneurysm was found intraoperatively at the graft renal artery anastomosis.After graft was evaluated as having no preservation value, the transplanted kidney and pseudoaneurysm were resected. Bacterial culture indicated Pseudomonas aeruginosa infection.The recipient recovered well and waited for next transplantation. Conclusions:Pseudoaneurysm of transplanted kidney is a very rare complication after renal transplantation, and caused by infection of Pseudomonas aeruginosa is more rarer, It has not been reported in mainland China.This type of recipient has the characteristics of high graft inactivation rate and high mortality rate. Timely surgical resection can effectively prevent the deterioration of disease.

On the 4th day of infection with HIV-1 in Macrophage cells, the expression of p24 antigen in 10-12, 10-10 and 10-8 mol/L dose of group (5) were (0.68?.15), (0.87?.41) and (0.75?.09) ng/ml respectively, compared to control [(0.60?.01) ng/ml, t= 7.27, 11.06 and 3.02, all P<0.05]. On the 6th day, 10-12, 10-10 and 10-8 mol/L dose of group (5) resulted in a significant increase of p24 antigen expression[(1.64?.57) , (2.07?.12 ) and (1.75?.17) ng/ml]in culture supernatants compared to control [(1.16?.07) ng/ml, t=8.93, 11.3 and 5.45, all P<0.01].On the 8th day, the expression of p24 antigen in 10-12, 10-10 and 10-8 mol/L dose of group (5) were (6.31?.17), (8.81?.34) and (7.19?.11) ng/ml respectively, compared to control [(3.84?.45) ng/ml, t=8.83, 15.11 and 12.42, all P<0.01]. On the 10th day, the expression of p24 antigen in 10-12, 10-10 and 10-8 mol/L dose of Morphine treated group were (32.30?7.55), (50.74?7.55) and (39.74?.56) ng/ml respectively, compared to control [(17.55?.86) ng/ml, t= 13.65, 17.84 and 36.69, all P<0.01].The enhanced multiple of p24 antigen expression in three doses of group (5) compared to control increased with HIV-1 infected Macrophage cells time, trend analysis of repeated measurements showed statistically significant time effect (F=135.58, P<0.01).Conclusions Morphine has the ability to enhance HIV-1 replication in MT2 cell and Macrophage. This Morphine-mediated increase of p24 antigen expression can be blocked by Naloxone.

Objective To observe the effect of the three active ingredients of a Chinese traditional medicine compound named Kang Fu Ling( KFL) against PC12 cells oxidative damage induced by microwave radiation.Methods PC12 cells were differentiated into neuros induced by nerve growth factor ( NGF ) .PC12 cells were incubated for 48 hours after astragalosides,total paeony glycoside and tanshinones were added at different concentrations (1, 3, or 9 μg/ml) .The cells in the control group were cultivated with the only medium of the same volume.Then, cells were irradiated with 30 mW/cm2 microwave for 6 minutes.The morphology of PC12 cells was observed under an inverted microscope soon before and after irradiation and the cell viability was measured by methylthiazolyl tetrazolium ( MTT) colorimetry.Reactive oxygen species ( ROS ) was determined using active oxygen probe 2′, 7′-dichlorodihyarofluolescen diacetde ( DCFH-DA ) while malonyldialdehyde(MDA) was measured in the homogenate of PC12 cells through thiobarbituric acid ( TBA) reactive substance assay.Results The cell morphology of each group showed no obvious difference.6 h after irradiation, the viability of irradiation control group measured by MTT declined apparently(P<0.01)compared with the normal control group.The 3 μg/ml astragalosides treatment group increased the viability of PC12 cells after microwave exposure ( P <0.01).The contents of ROS and MDA were increased after irradiation(P<0.01).However, in the three active ingredients of Kang Fu Ling treatment groups, both ROS and MDA were much lower than in irradiation control group.Conclusion Astragalosides, total paeony glycoside and tanshinones, which are the three active ingredients of Kang Fu Ling, all have protective effect against PC12 cell injury caused by microwave radiation,possibly by scavenging free radicals and reducing oxidative stress injury.

The aim of this study was to investigate the influence of opiate abuse on the expression of Toll-like receptor 9 (TLR9) in the peripheral blood mononuclear cells (PBMCs) of HIV-1-infected patients and to elucidate possible mechanisms involved in the enhancement of HIV-1 replication by opiate abuse. A total of 200 participants were enrolled in the study by random selection from methadone treatment centers and voluntary HIV counseling and testing centers in the cities of Nanning, Liuzhou, and Qinzhou. These participants included 50 HIV-positive opiate abusers (Opiates HIV(+) group), 50 HIV-negative opiate abusers (Opiates HIV(-) group), 50 HIV-positive subjects who were not opiate abusers (Non-opiates HIV (+) group), and 50 HIV-negative subjects who were not opiate abusers (Control group). PBMCs were isolated from the peripheral blood samples from the subjects and the expression levels of TLR9 mRNA and protein were determined by q-PCR and western blot respectively. There was no significant difference among the four groups in age, gender, nationality, domicile, marital status, educational background or duration of drug abuse (P > 0.05). The median viral loads of the Opiates HIV(+) were significantly higher than those of the Non-Opiates HIV(+) groups (4.450 x 10(3) and 3.977 x 10(3) copies/mL respectively, P < 0.05). The relative expression levels of TLR9 mRNA in the Opiates HIV(+), Non-Opiates HIV(+), Opiates HIV(-) and Control groups were (2.13 +/- 1.59) x 10(-3), (3.66 +/- 2.22) x 10(-3), (1.96 +/- 1.42) x 10(-3) and (7.66 +/- 4.87) x 10(-3), respectively. The expression of TLR9 mRNA was significantly lower in both HIV-1-infected and -uninfected groups of opiate abusers compared with groups of non-abusers (P < 0.05). There was no significant difference in TLR9 mRNA expression levels between the Opiates HIV(+) group and the Opiates HIV(-) group (P > 0.05). However, in the non-opiate groups, the expression levels of TLR9 mRNA in the HIV(+) group were significantly lower than that of the control group (P< 0.05). Western blot results confirmed that the expression of TLR9 protein was lower in the Opiates HIV(+), Non-Opiates HIV(+), and Opiates HIV(-) groups compared to the control group. These results suggest that opiate abuse can decrease the expression of TLR9 in PBMCs, which may result in the enhancement of HIV-1 infection and replication due to a decline in immune response mediated by the TLR9 pathway.

Objective To explore the feasibility of using short-latency somatosensory evoked potentials (SLSEP) to quantitate Deqi.Methods A randomized crossover controlled trial was carried out. Healthy subjects were enrolled and allocated to treatment (thick needle, deep insertion and manipulation for Deqi) and control (thin needle, shallow insertion and no manipulation without Deqi) groups. Somatosensory evoked potentials were recorded before, during and after acupuncture. Deqi was assessed using the score scale in the subjets. The effects of Deqi and no Deqi at point Sanyinjiao (SP 6) on the potentials were observed.Results The preliminary exploration of the feasibility by the trial test showed that the effect of Deqi on short-latency somatosensory evoked potentials had certain regularity. It was worthy to be observed.Conclusion The plan is feasible. The formal test can be conducted.

Objective To compare the genetic barriers to development of primary mutations related to drug resistance to protease inhibitors (PI), nucleioside reverse transcriptase inhibitors ( NRTI ), and non-nucleioside reverse transcriptase inhibitors ( NNRTI ) among human immunodeficiency virus (HIV)-1 CRF01_AE, CRF07_BC, and CRF08_BC strains, and to understand the difference of varying patterns of drug resistance related mutations within these subtypes. Methods One hundred and ninety naive HIV-positive subjects from Nanning City and Liuzhou City, Guangxi Zhuang Autonomous Region, were recruited. Peripheral blood samples were collected from all participants. HIV-1 RNAs were extracted from plasma, and the pol regions were amplified and sequenced. Sequences were subjected to phylogenetic analysis to determine the subtypes of HIV-1 isolates. Nucleotide transitions and transversions were counted for each primary mutation in these sequences. According to the phenomena that transitions occur on average 2. 5 times frequently than transversions, each transition was scored as 1, and each transversion scored as 2. 5. The sum of the scores for a particular substitution was calculated, and this value was taken as the genetic barrier to development of this mutation. Then, the differences of genetic barriers among the subtypes were assessed by Kruskal-Wallis test and Nemenyi test. Results A total of 123 sequences of CRF01_AE,CRF07_BC and CRF08_BC strains were selected. CRF08_BC had a lower genetic barrier for T/S69Dsubstitution than CRF01_AE and CRF07_BC (χ2 =107. 501, P＜0.01), while CRF01_AE and CRF07_BC had lower genetic barriers for V118I and L210W substitution than CRF08_BC. In addition,CRF07_BC had a decreased genetic barrier for V106M compared with CRF01_AE and CRF08_BC.Conclusions In the presence of the same selective pressure, subtypes CRF01_AE and CRF07_BC may be more likely to develop V118I and L210W substitution than CRF08_BC. However, CRF08_BC may be more likely to develop T/S69D substitution than CRF01_AE and CRF07_BC. Meanwhile, CRF07_BC may be easier to develop V106M substitution than CRF01_AE and CRF08_BC.

Objective By using infrared thermal imager (Flir-SC620), to observe the effect of needling Sanyinjiao (SP6) on the skin temperature at Guanyuan (CV4) and Sanyinjiao in patients with primary dysmenorrhea (PD) of cold and dampness stagnation pattern, and to explore the probability of using infrared thermal imaging for diagnosis and as an objective index for evaluating the action and needling qi of acupuncture. Method Thirty-six subjects were recruited and divided into four group, a health control group (group A), a control group of PD of cold and dampness stagnation pattern (group B), a needling-qi-expected group (group C) and a needling-qi-unexpected group (group D). Group A and B were not given acupuncture treatment, while group C and D were treated with acupuncture at bilateral Sanyinjiao with needles retained for 30 min, and the needling sensations were recorded. The infrared thermal imager was used to detect the skin temperature at Guanyuan and bilateral Sanyinjiao for 40 min for each group, and the temperature was recorded every 10 min. The temperature during different periods of time, 0-10 min, 20-20 min, 20-30 min, 30-40 min, 0-30 min, and 0-40 min were then calculated. In group C, those obtained the needling qi sensation were further grouped into C-1 and those didn’t obtain the sensation were into C-2; in group D, those obtained needling qi sensation were further grouped into D-1 and those didn’t obtain the sensation were into D-2. SPSS 17.0 was adopted for data processing, and the data were analyzed by using MANOVA of repeated measuring. Result Compared to group A (6 cases), the temperature at Guanyuan in group B (6 cases) was significantly decreased during 0-30 min and 0-40 min (P<0.05), the temperature at the left Sanyinjiao during 0-40 min in group B was significantly decreased (P<0.05), and the temperatures at bilateral Sanyinjiao during 30-40 min in group B significantly dropped (P<0.05). Compared to group B, the temperatures at Guanyuan during 0-30 min and 0-40 min in group C1 (12 cases) and group D1 (11 cases) were significantly increased (P<0.05), the temperature at left Sanyinjiao during 0-40 min in group D1 was significantly increased (P<0.05), and the temperatures at bilateral Sanyinjiao during 30-40 min in group D1 were significantly increased (P<0.05). There was no case in group C2 and only 1 case in group D2, hence, the data were not enough for analysis. Conclusion Decrease of the infrared temperature at Guanyuan and Sanyinjiao can be taken as one of the diagnostic criteria for dysmenorrhea of cold stagnation pattern. Increase of the infrared temperature at Guanyuan can be regarded as one of the objective evidences for the along-meridian transmission characteristic in needling Sanyinjiao.

Objective To investigate the expression of TLR 4 and its downstream factor TNF-αin the patients with human immunodeficiency virus and Mycobacterium tuberculosis ( HIV/MTB) co-infection. Methods A total of 119 subjects including 32 patients with HIV infection (HIV group), 30 patients with HIV/MTB co-infection (HIV/MTB group), 28 patients with MTB infection (MTB group) and 29 healthy subjects ( control group ) were recruited continuously from the Fourth People′s Hospital of Nanning City , Guangxi.The expression of TLR4 in peripheral blood mononuclear cells (PBMCs) from the patients was de-termined by flow cytometry .ELISA was performed to detect TNF-αin plasma samples .The HIV-1 viral load was determined by standard method .Results The mean fluorescence intensity ( MFI) for TLR4 expression in PBMCs from HIV, HIV/MTB, MTB and control groups were 21.62±4.67, 18.29±3.87, 16.79±4.45, and 22.85±5.80, respectively, showing significant differences among four groups (F=8.105, P<0.01). The TLR4 levels in MTB and HIV/MTB groups were significantly lower than those in control group ( both P<0.01) and HIV group (P<0.01, P=0.014).The plasma concentrations of TNF-αin HIV, HIV/MTB, MTB and control groups were 15.892 (10.494-21.646) pg/ml, 13.142 (8.014-22.038) pg/ml, 16.284 (11.916-24.005) pg/ml, and 26.657 (16.321-34.541) pg/ml, respectively, that were significantly dif-ferent from each other (F=4.350, P=0.006).The levels of TNF-αin plasma from patients with HIV and HIV/MTB infection were significantly lower than those of healthy subjects (P=0.009 and P=0.001).The viral load in patients from HIV/MTB group (5.113 ±1.018 copies/ml) was significantly higher than that from HIV group (4.416±1.020 copies/ml) (t=3.449, P=0.001).Conclusion MTB infection might promote HIV replication by inhibiting the expression of TLR 4.HIV infection might increase host′s suscepti-bility to MTB infection by reducing the production of TNF-α.Suppressed expression of TLR and TNF-αpro-duction could contribute to the occurrence of HIV /MTB co-infection .
