ABSTRACT:Objective To investigate the regulation of adenovirus type 36 infection on precursor protein particles progranulin expression in Uygur obese patients.Methods Based on the diagnostic criteria of obesity,the samples were divided into obese group and non-obese group.Serum neutralization test was used to detect the antibody of Ad36.The progranulin mRNA expressions in abdominal omental and subcutaneous adipose tissues were detected by real-time quantitative PCR.ELISA method was used to determine serum progranulin protein levels. CD68 protein expression of macrophage was detected by immunohistochemistry. Results ① In the Uygur population of our study,compared with that in the non-obese group (38/1 1 7,32.5%),the number of obese patients (54/1 1 5,47.0%)infected with Ad36 was significantly higher than that in non-obese group (P <0.05 ).② Serum progranulin was significantly increased in the Ad36-infected obese group (408.45±1 56.92)than in non-obese group (326.1 1±1 58.60)(P <0.05).The mRNA expression of progranulin did not differ between the two groups.③ The macrophage infiltration was significantly higher in the Ad36-infected obese group (14 730.1 6 ± 2 227.39 )than in non-obese group (10 786.50 ± 2 772.80 )(P < 0.05 ).Conclusion Ad36 infection may be associated with the occurrence of obesity in Uygur population,and adenovirus type 36 infection may regulate the expression of serum progranulin at the protein level.

Objective To investigate the clinical therapeutic effect of Chaishi fever particles on patients with epidemic encephalitis B and to study the machanism of anti-inflammatory.Methods One hundred and twenty one patients with epidemic encephalitis B admitted to the Second Clinical Medical College of Henan University of Chinese Medicine from January 2014 to May 2017 were enrolled, and they were divided into a routine treatment group (60 cases) and a traditional Chinese medicine (TCM) treatment group (61 cases) by random number table. The patients in routine treatment group were given symptomatic support and comprehensive treatment for 15 days, while those in the TCM treatment group were given as that of routine group with the addition of Chaishi fever particles 8 g, 4 times every day, orally taken for consecutive 15 days. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL-1β, IL-10) in the serum of two groups were determined by enzyme-linked immunosorbent assay (ELISA), and the clinical therapeutic effect, complications and sequelae in two groups after treatment were observed.Results Compared with the routine treatment group, after treatment the time of body temperature recovering normal (days: 5.8±1.2 vs. 7.5±1.7), the coma time (days: 5.5±1.3 vs. 6.8±1.6), the remission time of convulsion (days: 5.2±1.4 vs. 6.5±1.5), and the length of stay in hospital (days: 22.6±1.9 vs. 25.2±1.8 ) were significantly shorter in TCM treatment group (P < 0.05). After treatment, the levels of serum tumor TNF-α and IL-1β were decreased, IL-10 was increased in both groups, moreover, compared with the routine treatment group, the changes were more obvious in TCM treatment group [TNF-α (μg/L): 11.4±3.6 vs. 14.6±3.5, IL-1β (μg/L): 22.3±6.2 vs. 26.2±5.6, IL-10 (μg/L): 225.2±19.2 vs. 186.2±21.5, allP < 0.05]. In addition, compared with the routine treatment group, the total effective rate was higher [98.3% (60/61) vs. 90.0% (54/60),P < 0.05], and the incidence of sequelae was lower [1.64% (1/61) vs. 13.3% (8/60),P < 0.05] in TCM treatment group.Conclusion The Chaishi fever particles can effectively treat the patients with epidemic encephalitis B and the action is related to the inhibition of inflammatory reaction.

OBJECTIVETo explore the mechanism of prevention and treatment of post-PTCA restenosis with Xinmaitong (XMT).

METHODSRabbit carotid endothelial injury model was established using Fishman air drying method. Effect of XMT on model rabbits wild-type p53 gene expression was observed by tissue in situ hybridization.

RESULTSp53 gene expression appeared on the 3 days after operation, enhanced on the 7 days, reached the peak on the 14th day, weakened on the 21th, and still showed on the 28th day. The strongest expression was shown in rabbits treated by XMT, second in those treated by Warfarin, and the weakest in the operated control group.

CONCLUSIONXMT could promote the high expression of wild-type p53 gene expression in rabbit with carotid endothelial injury, which is possibly one of the important mechanism of XMT in preventing and treating arterial restenosis.

Objective To investigate the expression of extraeellular signal-regulated protein kinase (ERK1/2)pathway in rat brains with fluorosis and the effects of fluoride on learning and memory of the rats,and to reveal the mechanisms of damaged nervous system resulted from the toxicity of the ion.Methods Seventy-two SD rats were divided into 3 groups and 24 rats were in each group.Three groups were fed respectively with different concentrations of fluoride(NaF)for 6 months to establish rat models with fluorosis.Controls were fed with tap water (NaF＜0.5 mg/L):lower and higher concentration group were fed with water containing NaF(5,50 ms/L).Animals are sacrificed after 6 months of treatment with fluoride and the dissected brains were kept for analysis.The protein levels of ERK1/2 in rat brains were detected by Western-blotting and the mRNA level by RT-PCR. The spatial learning and memorizing ability was measured by Morris water maze test. Results The ERK1/2 protein in control group,lower and higher concentration group was 0.944±0.10,1.253±0.02,1.953±0.07,the differece being statistieally sighificant between any two groups (P ＜ 0.05). The phospho-ERKl/2 protein in control group,lower and higher concentration group was 0.73±0.08,0.77±0.07,1.28±0.11,the differece being statistieally sighificant between any two groups(P ＜ 0.05);the activation rate of phospho-ERK1/2 in lower and higher concentration group [(68.4± 3.8)%,(64.1±3.2)%] was decreased compared to control group[ (82.3±10.7)%],the differece being significant(P ＜ 0.05). In the navigation trial,longer escape latencies of lower concentration group on the second, the third,the fifth and the sixth day were observed[ (46.0±8.0),(24.0±2.7),(8.9±5.3),(7.4±4.1 )s] compared to the control[ (39.3±6.9),(19.1±9.1 ),(8.3±3.4),(4.8±2.7)s],the differece being significant (P ＜ 0.05 or ＜ 0.01 );the similar results were also observed in the higher concentration group[ (36.9±16.8),(37.7±12.9), (19.7±7.6),(12.2±5.7 )s],and the escape latencies of the higher concentration group on the third,the fifth and the sixth day were longer than that in lower concentration group. In the probe test,the rats took more time to reach the first cross in lower and higher concentration group[(1.17±0.75),(4.18±1.10)s] than control group[ (5.89± 0.56 ) s ],the differece being significant (P ＜ 0.05 or ＜ 0.01 ) ;stayed shorter [ ( 17.05±4.25 ),(18.20±4.57 ) s ] than control [(25.37±5.65 )s ] in platform area (P ＜ 0.01 );the activation rates of ERK1/2 were directly correlated with the time taken to reach the first cross platform located in the probe test(r = 0.364,P ＜ 0.05) and the activation rates were also directly correlated with the escape latencies on the sixth day(r = 0.497,P ＜ 0.05). Conclusion Long-term exposure of excessive fluoride induces the change of expression and activating rate of the ERK1/2 in rat brains,leading to the decreased capacity of learning and memory.

Objective To investigate the changes of oxidative stress level in brain tissues and serum, and learning and memory in rats with oxidative stress level in nerve damage in chronic fluorosis. Methods The rats were randomly divided into 3 groups according to the body weight, eight rats in each group, i.e., control group, drinking water containing less than 0.5 mg/L of fluoride; lower fluoride exposure group, drinking water containing 5 mg/L of fluoride; higher fluoride exposure group, drinking water containing 50 mg/L of fluoride. The animals were examined six months after initiating the experiment. The total antioxidant capacity (T-AOC) and malondialdehyde (MDA), as well as learning and memory, were measured. Results Escape latency in higher fluoride exposed group[ (14.37±3.48)s] was significantly higher than that of controls[ (5.84±1.87)s] and exposed te lower fluoride [ (7.18±1.42)s], the difference being statistically signifieant(P<0.05). As compared with controls[ (2.17±0.11)× 103 U/L , (0.79±0.11)×103 U/g Pr] ,the rats exposed to higher fluoride and lower fluoride exhibited lower levels of T-AOC [(1.37±0.27)×103 U/L,(0.24±0.06)×103 U/g Prand (1.20±0.14) x 103 U/L,(0.41 ~ 0.10)×103 U/g Pr], the difference being statistically signifieant(P<0.05). As compared with controls[ (2.34±0.16) mmoL/L, (2.97±0.11)mmol/g Pr] and low fluoride exposed group[ (2.68±0.33)mmoL/L, (3.38±0.21)mmol/g Pr], higher level of MDA were observed in higher fluoride exposed group[ (3.72±0.59)retool/L, (4.01±0.21)mmol/g Pr], the difference being statistically significant(P<0.05). Conclusion The results indicated that higher amount of fluoride induced an increased level of oxidation, which might result in the decreased capacity of intelligence of rats with fluorosis.

To analyze retrospectively Mr. Xie Xiliang's medical records accumulated in 30 years on direct moxibustion for treating hepatitis B, in which 86 cases were included. Before accepting direct moxibustion, 80.23% of the cases had been treated by conventional Chinese and western medicine, but no satisfactory therapeutic effects were obtained. Direct moxibustion was applied for 7-9 cones at each point selected. Point selection was related to ages. Usually, only a few points were used, and Ganshu (BL 18) and Pishu (BL 20) were used as main points. Shenzhu (GV 12) was added for children, and Zusanli (ST 36) added for adults. The improvement rate in clinical symptoms and physical signs were 100%. In the cases with hepatauxe, splenauxe, liver cirrhosis, and abdominal dropsy diagnozed by the B-ultrasonic examination, the improvement was obvious. Of the total, the rates turning to be negative in HBsAg, HBeAg and HBcAb were 28.85%, 38.46%, and 36.54%, respectively. It took some 10 days to 1 month to begin to show improvement in physical signs and hepetic functions, and about 3-6 months for their restoration. For the five items tested in type B hepatitis, it took 5 months to 1 year, even several years, to show their improvement. It is indicated that direct moxibustion is definitely effective in treating type B hepatitis. It is easy to handle and worth popularizing.

OBJECTIVETo discuss the anti-tumor effect of Xihuang pill on tumor-bearing rats and its effect on the immune clearance function of tumor-bearing organisms.

METHODWalker256 tumor cells were adopted to establish the tumor-bearing rat model. The rats were randomly divided into five groups: the normal control group, the model control group, the lentinan group and Xihuang pill low dose, middle dose and high dose groups, with 10 rats in each group, and continuously treated and given drugs for 14 d after modeling. Blood and tumors were collected from abdominal aorta to calculate the tumor inhibition rate. The content of CD3+, CD4+, CD8+ T cells and adhesion molecule B7-1 (CD80) in peripheral blood were detected by flow cytometry (FCM). The expressions of IL-2 and IFN-gamma in were determined by ELISA.

RESULTThe tumor inhibition rate of the Xihuang pill high dose group was 33. 1 percent. Compared with the model group, the Xihuang pill large dose group showed significantly low IL-2, IFN-gamma, CD3+, CD4+, B7-1 in peripheral blood, with statistical significance in their differences (P < 0.05).

CONCLUSIONXihuang pill could show its anti-tumor effect by enhancing the immune clearance function and increasing IL-2, IFN-gamma, CD3+ T, CD4+ T, B7-1 in peripheral blood.

Objective To observe the influence of coal burning fluorosis on learning and memory ability in rats and reveal its possible mechanisms. Methods Healthy 48 SD rats were divided into control, low-fluoride and high-fluoride group. All rats in fluoride exposed groups were fed with the eom polluted by drying processes with burning coal containing high level of fluoride obtained from the endemic fluorosis area to produce the animal model of fluorosis. The experiment period were 3,6 mouths, respectively. The ability of leaning and memory was measured by Morris test and cholinesterase activity detected by photometric method at 3 or 6 month after experiment, respectively. Results Fluoride contents signifieantlly influenced the escape latency, the numbers of crossing the platforms and the time of staying the platforms(the value of F was 29.29,6.47,6.50, respectively, P<0.01).In addition, the numbers of crossing the platforms and the time of staying the platforms were influenced by the exposed time(the value of F was 16.11,45.59, P<0.01). Furthermore, the fluoride contents and the exposed time had an interaction between the numbers of crossing the platforms and the time of staying the platforms (the value of F was 4.67,5.68, P<0.05 or<0.01). Three months after the experiment, the mean values of escape latency [(14.71± 4.85)s] of rats in highly fluoride exposed group were significantly prolonged as compared with controls [(9.28±4.22)s]; 6 month after the experiment, the mean values of escape latency[(12.42±8.03)s, (17.48± 8.05)s] of rats in both groups exposed to fluoride were significantly prolonged as compared to controls [(7.04± 3.29)s, P<0.05]. The decreased numbers of crossing the platforms[(1.62±0.87)number] and the declined time of staying the platforms[(16.70±5.02)s] were found in the rats exposed to high fluoride as compared to controls [(3.53±1.67 )number, (23.33±5.35)s, P<0.05]. The fluoride contents obviously influenced the activities of acetylcholinesterase and butylcolinesterase (the value of F was 12.83,13.27, P<0.01). On the other hand, the times of breeding also influnced the activities of butylcolinesterase (the value of F was 16.26, P<0.01). In 3 months of the experiment, the activities of butylcolinesterase [(0.55±0.12)kU/g] in low fluoride exposed group were significantly decreased in comparison with controls[(0.73±0.10)kU/g, P<0.05]. The activities of acetylcholinesterase[(0.62±0.42)kU/g] and butylcolioesterase[(0.58±0.10)kU/g] in high fluoride group were significantly decreased as compared to eontrois[(1.41±0.52), (0.73±0.10)kU/g, P<0.05]. The correlation analysis showed that there was a negative correlation between the cholinesterase and the escape latency(r=-0.68, P< 0.01), and a positive correlation between the cholinesterase and the time of staying the platforms(r=0.57, P< 0.01). Conclusions The ability of learning and memory in rats with coal buring fluorosis was decreased, which might be connected to the decreased activity of cholinesterase in a dose-effect correlation.
