OBJECTIVETo explore the optimal intervention time of acupuncture and moxibustion in the treatment of peripheral facial paralysis.

METHODSTwo hundred and four cases of peripheral facial paralysis were collected in clinic for retrospective analysis. According to the time between the disease onset and the intervention of acupuncture and moxibustion, 3 groups (groups A, B and C) were divided. In group A, the treatment was given in 1 to 3 days after onset; in group B, the treatment was given in 4 to 7 days after onset; in group C the treatment was given in 8 to 10 days after onset. The treatment with acupuncture and moxibustion was applied according to the regular stages of disease in the three groups. At the acute stage, the less points and shallow puncture therapy combined with distal acupoints at the limbs were adopted on the affected side. At the stable stage, the more points and shallow puncture therapy were used on the affected side. At the recovery stage, the deep puncture or penetrating punctures was applied on the affected side. The curative effects was given once every day and the treatment of 10 days made one session. The curative effects were analyzed statistically at the end of three sessions of treatments separately.

RESULTSAt the end of the 1st session of treatment, the total effective rate was 58.8% (40/68) in group A, 69.7% (53/76) in group B and 46.6% (28/60) in group C. At the end of the 2nd session of treatment, the total effective rate was 85.3% (58/68), 90.8% (69/76) and 71.6% (43/60) in group A, B and C separately. At the end of 3rd session of treatment, the total effective rates were 89.7% (61/68), 97.4% (74/76) and 83.3% (50/60) in the three groups separately. The differences were significant statistically at the same session of treatment among three groups (all P<0.05), in which, the results in group B was the best, followed by group A and C in sequence.

CONCLUSIONthe best intervention time of acupuncture and moxibustion is in 4 to 7 days after onset of facial paralysis.

A simple and efficient method, based on ultrasound-assisted polymer surfactant-enhanced emulsification microextraction followed by gas chromatography-mass spectrometry( GC-MS) , was developed for the determination of eight aromatic amines ( AAs ) in aqueous sample. The main parameters affecting the performance of the purposed method were optimized, and the optimized conditions were obtained as follows:150 μL of extractive solvent ( dichloroethane ) , polymer surfactant ( sodium alginate ) concentraction of 0. 20 g/L, pH 7. 0, salt addition of 3%, and ultrasound time of 1 min. Under the optimal conditions, the linear ranges of the method were 0. 1-200 μg/L for 3,3’-dichlorobenzidine, 0. 3-200 μg/L for 2,4,5-trimethylaniline, 4-chloro-o-toluidine, 3,3’-dimethyl-4,4’-diaminodiphenylmethane, 3,3’-dimethylbenzidine and 4 , 4’-methylene-bis-( 2-chloroaniline ) , 0 . 5-200 μg/L for 4-aminoazobenzene and 3 , 3’-dimethoxy-benzidine. The correlation coefficients (R2) and the detection limits were 0. 9961-0. 9997 μg/L and 0. 08-0. 3 μg/L, respectively. The intra- and inter-day RSDs were less than 10. 6% and 11. 0%. The purposed method could be applied to the analysis of AAs in water sample collected from tap water and river water. In comparison with the common SA-USAEME, conventional surfactant was replaced with water-soluble polymer surfactant to solve the problems of potential pollution, and the polymer surfactant was natural and insoluble in extractive solvent. Compared with other solid-phase extractions, the proposed method had the advantages such as simple operation and low cost.

Objective To investigate the effects of preoperative jaundice relieving on hemihepatectomy of hilar cholangiocarcinoma.Methods The clinical data of 18 patients who received preoperative percutaneous transhepatic cholangiography and drainage (PTCD) or endoscopic nasobiliary drainage (ENBD) before hemihepatectomy at the Tongji Hospital of Huazhong University of Science and Technology from January 2007 to January 2012 were retrospectively analyzed.The condition of the 18 patients (jaundice relieving group) was compared with that of 24 patients (non-jaundice relieving group) who did not receive PTCD or ENBD before hemihepatectomy.The differences in the pre-and postoperative blood loss,blood transfusion,operation time and postoperative incidence of complications between the 2 groups were analyzed.All data were analyzed using the t test or chi-square test.Results After PTCD or ENBD,the levels of total bilirubin (TBil),direct bilirubin (DBil),alanine aminotransferase (ALT) were (27 ± 5) μmol/L,(22 ± 6) μmol/L and (52 ± 42) U/L,which were significantly lower than (287 ± 120)μmol/L,(212 ± 86)μmol/L,and (267 ± 180)U/L before PTCD or ENBD in the jaundice relieving group (t =4.33,6.61,4.19,P ＜0.05).In the jaundice relieving group,left hemihepatectomy was performed on 14 patients,and right hemihepatectomy on 4 patients,and the radical resection rate was 16/18.In the nonjaundice relieving group,left hemihepatectomy was performed on 11 patients,and right hemihepatectomy on 13 patients,and the radical resection rate was 83.3％ (20/24).There was no significant difference in the radical resection rate between the 2 groups (x2 =1.09,P ＞ 0.05).The operation time,volume of intraoperative blood loss,volume of blood transfusion were (5.0 ± 0.8) hours,(562 ± 207) ml and (430 ± 317) ml in the jaundice relieving group,and (6.3 ± 1.5)hours,(815 ± 463)ml and (750 ± 146)ml in the non-jaundice relieving group,with significant differences between the 2 groups (t =4.77,7.80,4.65,P ＜ 0.05).The incidences of postoperative complications,bleeding and postoperative hepatic failure were 3/18,1/18 and 1/18 in the jaundice relieving group,and 75.0％ (18/24),33.3％ (8/24) and 33.3％ (8/24) in the non-jaundice relieving group,with significant differences between the 2 groups (x2=5.14,7.58,7.58,P ＜ 0.05).Conclusion Preoperative jaundice relieving could shorten the operation time and reduce the volume of intraoperative blood loss and the incidence of postoperative complications.

Objective To discuss the effects of bone marrow-derived mesenchymal stem cells (MSCs) on vascular endothelial growth factor (VEGF) in lung tissue and in plasma, and extra-vascular lung water at the early stage of smog inhalation injury. Method The rabbit model of smog inhalation injury was established by using home-made smog generator, and the rabbit models were randomly(random number) divided into control group (group S, n = 32) and MSCs treatment group (group M, n = 32). Ten mL phosphate-buffered saline (PBS) was injected into ear marginal vein immediately after injury in rabbits of group S. The third generation of MSCs 1/10/10 mL PBS was injected into ear marginal vein immediately after injury in rabbits of group M. The levels of VEGF in peripheral blood and lung tissue were neasured 0 h,2 h,4 h and 6 hours after injection respectively, and analyzed. The right lung of rabbits was taken out to measure and calculate lung water mass fraction after experiment.Results In lung tissue, the levels of VEGF decreased gradually in group S (P ＜ 0.05), and though the levels of VEGF in lung tissue appeared with significant decreasing trend in group M (P ＜ 0.05), they were still higher than those of group S at corresponding intervals ( P ＜ 0.05). In peripheral blood, the levels of VEGF increased gradually in group S ( P ＜ 0. 05), and the levels of VEGF in group M appeared with markedly increasing trend ( P ＜ 0.05),but they were lower significantly than those in group S at corresponding intervals ( P ＜ 0.05). Conclusions MSCs engraftment to the rabbits with smog inhalation injury could increase VEGF in lung tissue, decrease VEGF in plasma and reduce extra-vascular lung water, showing protective effect on smog inhalation injury to a certain extent.

Objective To analyze behavior of having multiple sexual partners among outside school adolescents and the impact factors in one county.Method Participatory method was adopted in the survey,trainees of an occupational training center were trained to investigate their peers with anonymous questionnaires.Results The subjects who had more than 3 sexual partners accounted for 38.3%,and the factors related to multiple sexual partners were complicated.The most im- portant protective factor was to raise level of HIV/AIDS related knowledge (OR=0.85);the key risk factors were: promiscuous behaviors (OR=4.91) and prostitution(OR=3.37) among their friends.Conclusion For reducing behav- ior of having multiple sexual partners among outside school adolescents,it is essential to promote HIV/AIDS related health education and to enhance their ability to respond to pressures from their bad peers.

OBJECTIVETo compare the changes of nucleus pulposus after in vitro culture of rabbit whole intervertebral disc and spinal motion segment.

METHODSTwenty-one New Zealand white rabbits which were randomly divided into organ group with 8 rabbits and segment group with 13 rabbits. Fifty intervertebral discs and 50 spinal motion segments were harvested respectively under aseptic conditions from two groups. These specimens were maintained in organ culture with hyperosmotic media (410 mOsm/kg), then 10 discs of the two groups were observed respectively by HE staining, immunohistochemistry of collagen type III, proteoglycan content and cells viability of nucleus pulposus before culture and at 3, 7, 14, 21 days after culture.

RESULTSHE staining showed the intervertebral disc tissue structure remained intact after culture of 21 days organ group and 14 days segment group,but there was severely degenerated of 21 days segment group. The intensity value of type II collagen immunohistochemical staining in the nucleus pulposus were not changed significantly between 21 days organ group and 14 days segment group (P > 0.05), but the staining of segment group at 21 days became shallower, there was significant difference compared with before each time points and organ group at 21 days (P < 0.05). PAS/AB staining of proteoglycan of nucleus pulposus showed that there were not decrease of tinting strength of two groups within 7 days, but the strength weakened slightly of two groups at 14 days, and the tinting strength became weaker at 21 days segment group, the change is more obvious than the organ group. The intensity value of fluorescence staining of nucleus pulposus cells was not changed significantly within 7 days of two groups (P > 0.05), the intensity value decreased slightly at 21 days organ group and 14 days segment group, but there were no significant difference compared with before time points (P > 0.05) however at 21 days segment group the intensity decreased as cells viability of nucleus pulposus decreased,and there was a significant difference compared with before each time points and organ group at 21 days (P < 0.05).

CONCLUSIONIt is not obviously degenerated of the discs of organ group cultured within 21 days and segment group cultured within 14 days, but there was significant degeneration of the intervertebral disc of segment group after cultured 21 days, so the rabbit spinal motion segment can be used on research about the biomechanics of intervertebral disc as a vitro experimental model within 14 days.

Objective To analyze the changing rules of schistosomiasis endemic situation before and after reaching the crite-ria of schistosomiasis transmission controlled or transmission interrupted in Zhejiang Province,so as to provide scientific evi-dence for schistosomiasis contro1. Methods Xiuzhou District and Zhuji City were selected and investigated retrospectively to collect schistosomiasis epidemiological information 10 years before they reached the criteria of transmission controlled and the subsequent years until 2008. The database of retrospective investigation was established for analyzing the trends and rules of changes of Oncomelania hupensis snail status and schistosome infection status of cattle and human. Results The snail status and schistosome infection kept a steady declining before reaching the criteria of transmission controlled ,and there were positive correlations between the area of living snails and the infection rates of human and animal in two places(rhuman=0.764,P<0.01, rcatl e=0.709,P<0.01;rhuma=0.775,P<0.01,rcatl e=0.676,P<0.01);No local infection person and animal except residual snails, and found 7 cases of imported infection source were found after reaching the transmission interruption. Conclusion The epi-demic status of schistosomiasis in zhejiang is stable after reaching the criteria of transmission interruption ,and residual snail are easy to re-found and spread under some certain conditions,and some imported cases were found sometimes,which may in-crease the risks for re - emergence of schistosomiasis. The integrated solidification strategy with emphasis on control of residu-al snails and imported cases should be taken in the areas of transmission interruption in the future.

BACKGROUND:Studiesin vitro have suggested that icarin can attenuate lipopolysaccharide (LPS)-induced acute pneumonia. Is the anti-inflammatory effect of icarin stil valid in the presence of wear particles? OBJECTIVE:With studiesin vivo andin vitro, to investigate the regulatory effect of icarrin on titanium particle-induced inflammatory reaction. METHODS:(1) Studiesin vivo: Eighty male C57BL/6 mice aged 6-8 weeks were randomly divided into four groups: control group, icarin group, titanium particle group, and titanium particle+icarin group. Mice in the titanium particle group and titanium particle+icarin group received surgical procedure, and sterile and endotoxin-free titanium particles were implanted on the calvaria surfaces to induce inflammatory reaction. Mice in the control group and icarin group received the same surgery, but no wear particles were implanted. Then icarin was given oraly to mice in the titanium particle group and titanium particle+ icarin group with a dose of 200 mg/kg per day for 2 weeks from the day of modeling. Mice in the control group and icarin group were given oraly the same dose of placebo. Two weeks later, tumor necrosis factor-α and interleukin-1β at protein and mRNA levels were respectively detected with enzyme-linked immunohistochemical (ELISA) and quantitative real time reverse transcription PCR (qRT-PCR) analysis. (2) Studiesin vitro: Mouse monocyte/macrophage RAW264.7 cels were cultured with different conditioned media: control group, nuclear factor receptor ligand кB (RANKL); icarin group, RANKL+icarin; titanium particle group, RANKL+titanium particles; titanium particle+icarrin group, RANKL+icarin+titanium particles. Titanium particles stimulated RAW264.7 cels were co-cultured with RANKL and icarin for 72 hours. Tumor necrosis factor-α and interleukin-1β at protein and mRNA levels in the supernatant were detected with ELISA analysis and qRT-PCR, respectively. RESULTS AND CONCLUSION: (1) Resultsin vivo: icarin treatment obviously decreased titanium particle-induced inflammatory cellinfiltration and made the thickness of periosteum thinner, down-regulated tumor necrosis factor-α and interleukin-1β expressions at protein and mRNA levels. (2) Results in vitro: when RAW264.7 cels were stimulated with titanium particles for 72 hours, tumor necrosis factor-α and interleukin-1β expressions at protein and mRNA levels in culture media increased obviously; when icarin was administrated, tumor necrosis factor-α and interleukin-1βexpressions at protein and mRNA levels down-regulated significantly. These results suggest icarin can obviously suppress titanium particle-induced inflammatory reactionin vivo andin vitro.
