OBJECTIVETo compare the efficacy difference between acupuncture and western medication in the treatment of knee osteoarthritis.

METHODSOne hundred and twenty cases were randomly divided into an acupunc ture group and a western medication group, 60 cases in each group. In acupuncture group, acupuncture was applied mainly to Neixiyan (EX-LE 4), Dubi (ST 35), Yinlingquan (SP 9) and Yanglingquan (GB 34) and to the other acupoints selected according to syndrome differentiation. In western medication group, Glucosamine Hydrochloride capsules were applied for oral administration, 2 capsules each time, 3 times per day. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)and Medical Outcomes Study 36-Item Short Form Health Survey (SF-36, Chinese version) were used to assess the therapeutic effect before treatment, after 4 weeks treatment and in follow-up visit of 9 weeks after treatment separately.

RESULTSAfter 4 weeks treatment, the total effective rate was 86.7% (52/60) in acupuncture group and was 88.3% (53/60) in western medication group, indicating no statistical significant difference in the comparison between two groups (P > 0.05). In 9 weeks after treatment, the total effective rate was 83.3% (50/60) in acupuncture group, which was better than 61.7% (37/60, P < 0.05) in western medication group. The scores of WOMAC and SF-36 were all improved after treatment as compared with those before treatment in two groups (P < 0.05, P < 0.01). There were no significant differences in comparison between two groups after 4 weeks treatment (all P > 0.05). But, in follow-up visit of 9 weeks after treatment, the scores of WOMAC and SF-36 in acupuncture group were superior to those in western medication group (P < 0.05, P < 0.01).

CONCLUSIONThe short-term efficacies on osteoarthritis of knee in acupuncture group according to syndrome differentiation are similar to that of oral adiministration of Glucosamine Hydrochloride, but the long-term efficacy in acupuncture group is better than that in western medication group.

Objective To explore the relationship between wild rodent plague and human in wild rodent plague foci of the northwestern area in Yunnan to probe the possible transmission mechanism of wild rodent plague to human. Methods Data of component ratio of rodents and fleas was collected in different areas from 1985 - 1995. Activities and habits of residents regarding the way they keep cats and dogs and parasitic fleas and free fleas indoor were investigated, the dog serum was collected for detecting F1 antibody. Results Eothenomys miletus were main rodents in farmland and shrub, accounting for 48.00% (4753/9902) and 54.50% (4282/7857), Apodemus chevrieri were main rodents in garden, being 50.47% (1332/2639). The component ratio of Neopsylla specialis specialis was 13.31%(229/1720), 12.31%(1678/13 739) and 10.87%(957/8802) respectively in garden, farmland and shrub, higher than in indoor. The component ratio of Frantcpsylla spodix was 39.88% (686/1720), the highest in garden. Thirty-two per cent (32/100) of residents kept cats,in which 63% (20/32) with cat fleas, 68% (68/100) of villages kept dogs, in which 76%(52/68) with fleas. Eighteen parasitic fleas were caught from 43 dogs with a flea index of 0.119 and a rate for fleas of 11.63%, 7 pulex were collected from 17 indoor. Forty-three blood serum samples were obtained from dogs, among which 3 were positive blood serum. Conclusions Residents touch affected animals or media in different situations. The possibility of transmission for wild rodent plague to human exists in loci in a chain of wild rodent plague → fleas or predation → homebred animal plague (cats or dogs) →touching or respiratory → human.

Objective To investigate the iodine nutritional status of residents in coastal areas of Fujian province,and to provide evidence for effective implementation of preventive strategy of scientific supplying of iodine.Methods In 2009,in Fujian province,6 cities were selected,then one area in every city was selected.A District Office was selected in every area,and then 1 Residents Committee in every District Office was selected.Eleven counties were selected,1 township in each county was selected,and then 1 village in each township was selected.Thirty families were selected in each Residents Committee(village),and then iodine content in household drinking water and salt were tested.The per capita salt intake in the households was calculated using 3 days weighing method.Twenty adults aged 18 to 45 were selected to test their urinary iodine; thirty pregnant and lactating women and 50 children aged 8 to 10 in each street(township ) were selected to test their urinary iodine(UI).Results One hundred and fifty three,30,94,183 and 62 families in coastal cities,inland cities,inland rural areas,coastal rural areas,and coastal mountain areas were surveyed,respectively.The median iodine content of salt was 28.4 - 30.8 mg/kg.The coverage rate of iodized salt and the qualified iodized salt consumption rate were all above 90％ in coastal cities,inland cities,inland rural areas and coastal mountain areas.The coverage rate of iodized salt and the qualified iodized salt consumption rate were 86.9％(159/183) and 83.6％(153/183) in coastal rural areas.In coastal cities,coastal rural areas,inland rural areas,inland cities and coastal mountain areas,258,300,110,160 and 101 children aged 8 - 10 were surveyed,respectively,and the median UI were 191.0,165.6,267.7,269.0 and 161.0 μg/L,respectively.One hundred and one,123,118,63 and 41 adults were surveyed,respectively,and the median UI were 197.6,203.4,174.7,302.8 and 154.9 μg/L,respectively.One hundred and fifty one,181,50,101 and 63 pregnant were surveyed,respectively,and the median UI were 156.5,141.7,116.2,163.0 and 126.2 μg/L,respectively.One hundred and fifty four,184,40,111 and 70 lactating women were surveyed,respectively,and the median UI were 130.3,118.8,110.9,154.6 and 175.9 μg/L,respectively.Conclusions The iodine nutritional level of residents in coastal areas is suitable,and iodine excess does not exists.Coastal areas still need to supply iodized salt.We should be highly concerned about the status of iodine nutrition of pregnant women and put this part of population into routine monitoring.

The aim of this study was to investigate the proliferation-inhibitory and inducing apoptotic effects of decitabine (DAC) on acute promyelocytic leukemia NB4-R2 cells. Cell inhibitory rate was determined by cell proliferation and cytotoxicity assay (WST-1 assay) after NB4-R2 cells were treated with 0.01 - 0.5 µmol/L DAC for 24, 48 and 72 h. Apoptosis of NB4-R2 cells treated with 0.05 - 5 µmol/L DAC for 48 h was detected by flow cytometry with PI staining and AnnexinV/PI staining. Reverse transcription-PCR (RT-PCR) was used to determine the mRNA expression level of MDR1 gene encoding P-glycoprotein (P-gp). The results indicated that DAC (0.01 - 0.5 µmol/L) inhibited the proliferation of NB4-R2 cells in both time- and concentration-dependent manners. The IC(50) of DAC on the viability of NB4-R2 cells after treatment for 48 and 72 h were 0.089 and 0.064 µmol/L respectively. DAC (0.05 - 5 µmol/L) induced NB4-R2 cell apoptosis in dose-dependent manner with down-regulation of MDR 1 gene expression. It is concluded that a low concentration of DAC (< 0.5 µmol/L) inhibits cell proliferation, while higher concentration of DAC (1 or 5 µmol/L) induces apoptosis on NB4-R2 cells, accompanied with reduction of MDR1 levels.

OBJECTIVE: To establish a database of high-fall death cases for future forensic study and practice, based on the scene investigation, injury characteristics and other informations. METHODS: Five hundred and four cases of high-fall death from 5 provinces and cities were included in the study. Data including personal information of the deceased, scene investigation, autopsy findings, history of mental illness and the results of toxicology were collected and analyzed. RESULTS: The male accidental death rate was significantly higher than that of female. No case of suicide was found in the 0-10 age group, while the suicide rate was apparently higher in the 60 years or over age group than that of accident. Most of the accident cases occurred at workplace, with head landing first and foot or lower-extremity landing first observed from height below 10 m and between 10-25 m, respectively. CONCLUSION The majority of cases have obvious conclusions. A substantial set of the cases, however, is still difficult to determine the mechanism of injury and the manner of death. So further study should be performed.

OBJECTIVETo investigate the relationship of susceptibility loci in chromosomes 1q21-25 and 6p21-25 and schizophrenia subtypes in Chinese population.

METHODSA genomic scan and parametric and non-parametric analyses were performed on 242 individuals from 36 schizophrenia pedigrees, including 19 paranoid schizophrenia and 17 undifferentiated schizophrenia pedigrees, from Henan province of China using 5 microsatellite markers in the chromosome region 1q21-25 and 8 microsatellite markers in the chromosome region 6p21-25, which were the candidates of previous studies. All affected subjects were diagnosed and typed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revised (DSM-IV-TR; American Psychiatric Association, 2000). All subjects signed informed consent.

RESULTSIn chromosome 1, parametric analysis under the dominant inheritance mode of all 36 pedigrees showed that the maximum multi-point heterogeneity Log of odds score method (HLOD) score was 1.33 (α = 0.38). The non-parametric analysis and the single point and multi-point nonparametric linkage (NPL) scores suggested linkage at D1S484, D1S2878, and D1S196. In the 19 paranoid schizophrenias pedigrees, linkage was not observed for any of the 5 markers. In the 17 undifferentiated schizophrenia pedigrees, the multi-point NPL score was 1.60 (P= 0.0367) at D1S484. The single point NPL score was 1.95(P= 0.0145) and the multi-point NPL score was 2.39 (P= 0.0041) at D1S2878. Additionally, the multi-point NPL score was 1.74 (P= 0.0255) at D1S196. These same three loci showed suggestive linkage during the integrative analysis of all 36 pedigrees. In chromosome 6, parametric linkage analysis under the dominant and recessive inheritance and the non-parametric linkage analysis of all 36 pedigrees and the 17 undifferentiated schizophrenia pedigrees, linkage was not observed for any of the 8 markers. In the 19 paranoid schizophrenias pedigrees, parametric analysis showed that under recessive inheritance mode the maximum single-point HLOD score was 1.26 (α = 0.40) and the multi-point HLOD was 1.12 (α = 0.38) at D6S289 in the chromosome 6p23. In nonparametric analysis, the single-point NPL score was 1.52 (P= 0.0402) and the multi-point NPL score was 1.92 (P= 0.0206) at D6S289.

CONCLUSIONSusceptibility genes correlated with undifferentiated schizophrenia pedigrees from D1S484, D1S2878, D1S196 loci, and those correlated with paranoid schizophrenia pedigrees from D6S289 locus are likely present in chromosome regions 1q23.3 and 1q24.2, and chromosome region 6p23, respectively.

OBJECTIVETo explore the short-term outcomes and safety of complete mesocolic excision (CME) in elderly patients with colon cancer.

METHODSThe clinical pathological factors of 71 patients with colon cancer undergoing CME procedure by the same group of surgeons were analyzed retrospectively from November 2009 to February 2012. The elderly group(≥70 years) and the non-elderly group(<70 years) were compared regarding short-term outcomes and safety.

RESULTSSimilar extent of resection could be achieved in the elderly and non-elderly groups in terms of area of mesentery[(13 049±4332) vs. (13 163±4725) mm2, P=0.916], distance between the tumor and the high ligation site[(95±22) vs. (98±20) mm, P=0.516], distance between normal bowel and high ligation site [(130±25) vs. (128±25) mm, P=0.731], the length of colon [(262±60) vs. (245±49) mm, P=0.212], and lymph nodes retrieved(22.0±6.4 vs. 24.8±9.9, P=0.168). The mean operative time, intraoperative blood loss, postoperative complications, time to first flatus, time to first bowel movement, drainage removal time, diet resumption, drainage volume in three days after surgery, and hospital deaths showed no statistical significances(all P>0.05), while hospital stay and expenses of the elderly group were significantly increased(both P<0.01).

CONCLUSIONElderly patients undergoing elective CME operation can achieve similar operative extent and lymph nodes harvest, and the surgical risk is not increased.

Kawasaki disease (KD) is a febrile disease mainly observed in children aged <5 years, with medium- and small-vessel vasculitis as the main lesion. Although KD has been reported for more than 50 years and great progress has been made in the etiology and pathology of KD in recent years, there is still a lack of specific indicators for the early diagnosis of KD, especially with more difficulties in the diagnosis of incomplete Kawasaki disease (IKD). At present, there are no clear diagnostic criteria for IKD, which leads to the failure of the timely identification and standardized treatment of IKD in clinical practice and even induce the development of coronary artery lesion. This article reviews the concept, epidemiological features, diagnosis, treatment, and follow-up management of IKD, in order to deepen the understanding of IKD among clinical workers and help to improve the clinical diagnosis and treatment of KD in China.
