The traditional Chinese medical knowledge service and information sharing system(V1.1.5) was applied to construct database. The regulating liver core combination of drugs, drug application mode, and combined treatment of diseases and syndromes were determined by analysis methods of frequency and association rules. Results The use of regulating liver method was often used in the treatment of irregular menstruation, cirrhosis, pain and other diseases. Differentiation of liver qi stagnation, blood stasis, liver stagnation and spleen deficiency, liver and kidney deficiency were the main TCM syndromes. Treatment included Tongluo, nourishing Yin treatment. The core drugs were Bupleurum and Rhizoma Cyperi. Conclusions The use of traditional Chinese medical service and knowledge sharing system could explore the clinical diagnosis and medication rules of regulating liver methods.

Objective To understand health seeking behavior and its influential factors to reproductive tract infections (RTIs) on women at reproductive age in the rural areas. Methods 54 540 fertile women aged 15-49 were surveyed by a stratified-cluster-random sampling method and gynecological examination were conducted in two steps: converging at the clinics, and then visiting their households, later, 31 624 women who had at least one RTI symptom were chosen. Results Among all the women at reproductive age, the rate of having at least one RTI symptom was 59.8% with the means of RTI symptom as 1.66±0.89. 15 989 women went to see doctors out of the 31 624 women who had RTI symptoms, with a proportion of 50.6 %. The results of logistic regressy showed that those women whose husbands having higher education level, higher income, more RTI symptoms and better knowledge on RTI were more easily to go to the hospitals. However, those women whose husbands working out of the county, having older first bearing age and more numbers of pregnancy were less likely to go to the hospitals. Reasons that refrained them from going to see a doctor would include: 2137(13.7%) did not know that RTI was a disease; 7443(47.6%) of them thought that every woman were bound to have at least one symptom and it did not matter; 1629 (10.4%) of them felt shameful; 349 (2.2%) learned that the diseases were incurable; 975 (6.2 % ) felt the cost of treatment was too expensive; 2101 (13.4 %) had no time; 1001 (6.4 %) would treat themselves through buying medicines over the counter. Conclusion RTI symptoms were quite prevalent among women at reproductive age but the rate of seeing a doctor was low and caused by multi-factors. Health education and gynecological census in increasing the curable rate of RTIs should to be strengthened.

Objective To observe the changes of behavior,blood cortisol level,glucocorticoid receptors (Grs) and mineralocorticoid receptors (MRs) in hippocampus area after four weeks of unpredictable chronic mild stress,and to investigate the probable role of hypothalamus-pituitary-adrenal (HPA) axis in the pathogenesis of depression in aged people.Methods Aged male Wister rats were randomly assigned to control group and model group.The model group received unpredictable mild stress,including food and water deprivation,restrain,tail clipping,forced swimming,white noise,cage titling and cage rotating for 4 weeks,while the control group was undisturbed unless routine feeding and cage changing.After 4 weeks of procedure,the behavior changes were assessed by sucrose intake test,open-field test and state evaluation,serum cortisol level was measured by chemiluminescent assay,the qualitation and quantitation of GRs and MRs in hippocampus area were evaluated by immunohistochemistry and Western blotting respectively.All data were analyzed by using t-test.Results Body weight,the grooming score,activities in openfield test,food intake and sucrose intake were decreased in model group as compared with control group after 2 weeks of chronic mild stress (all P＜0.01),suggesting the stress induced depressive-like behavior effects on aged rats.Serum cortisol level was elevated in model group as compared with control group after 4 weeks of chronic mild stress (P＜0.01).A decrease of the neurons was found in CA3 of hippocampus,but not in DG area.In CA3 area,GR positive neurons were decreased,but no significant decrease was found in MR positive neurons.Conclusions The chronic mild stress leading to depressive-like behavior effects in aged rats induces overall HPA axis dysfunction,elevation of serum cortisol level,impairment of hippocampus neurons and decrease of GR positive neurons.The HPA axis dysfunction induced by chronic mild stress may play an important role in the pathogenesis of depression.

Objective To explore the expression of N-myc downstream regulated gene 1 (NDRG1) in gastric carcinoma and the relationship with clinicopathological parameters and prognosis. Methods The expression of NDRGI was detected by immunohisto chemistry in formalin-fixed and paraffin-embedded sections with a total of 220 specimens including 110 gastric carcinoma and 110 corresponding paraneoplastic tissue. The correlation between clinicopathological parameters and the expression of NDRG1 in gastric carcinoma were also analyzed. Results Low expression of NDRG1 was detected in most gastric carcinoma sections. Among the gastric cancer tissues, NDRG1 protein expression was significantly lower in tumors with more advanced pathological stage, local tumor invasion and lymphatic metastases. There was no significant difference in sex, age, tumor differentiation and gross types of the tumor. The 1-, 3- and 5 year survival and disease free survival in patients with low NDRG1 protein expression was 84.2%, 53.9%, 21.1%, and 60.5%, 31.6%, 19.7%, respectively, which was signifivantly poorer when compared with patients with high NDRG1 protein expression. Conclusion The expression of NDRG1 is low in the majority of patients with gastric carcinoma, which was in a close relationship with advanced stage, local invasion and lymphatic metastases of gastric carcinoma. NDRG1 may be a candidate metastasis suppressor gene.

OBJECTIVETo study clinical effects of short-segment fixation and injured vertebra bone grafting through injured pedicle for the treatment of thoracolumbar burst fractures under MAST Quadrant retractor via a paraspinal muscle approach.

METHODSThe data of 42 patients with thoracolumbar burst fractures treated from June 2009 to September 2012 were reviewed. There were 19 males and 23 females, with an average age of (55.2±11.9) years old. The mean injury time was (5.8±4.3) days. Fracture segments included T10 in 3 cases, T11 in 6 cases, T12 in 13 cases, L1 in 9 cases, L2 in 7 cases, and L3 in 4 cases. According to Denis classification, 9 patients were type A, 21 patients were type B, 5 patiens were type C, 5 patients were type D, and 2 patients were type E. All the patients were treated with short-segment pedicle screw-rod system fixation under MAST Quadrant via the paraspinal muscle approach. The operative time, blood loss, complications and the height of vertebra, kyphosis Cobb angle, VAS scores, JOA scores were measured before and after treatment.

RESULTSAfter treatment, the vertebral height and kyphosis Cobb angle were restored. Compared with preoperative results, postoperative vertebral height and kyphosis Cobb angle, VAS scores and JOA scores were all improved. But there was no statistically significance in vertebral height, kyphosis Cobb angle between postoperative at 1 week and 1 year.

CONCLUSIONInternal fixation combined with injured vertebra bone grafting through the injured pedicle for the treatment of thoracolumbar burst fractures via the paraspinal intermuscular approach under MAST Quadrant is a safe, minimally invasive, effective and satisfactory method.

Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma were widely used in strengthening spleen under different disease conditions, and were easily and often misused each other. Therefore, DNA barcode was used to distinguish Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from their adulterants to ensure the safe use. The sequence lengths of ITS2 of Atractylodes macrocephala, Atractylodis Rhizoma (A. lancea, A. japonica and A. coreana) were both 229 bp. Among the ITS2 sequences of A. macrocephala, only one G/C transversion was detected at site 98, and the average GC content was 69.42%. No variable site was detected in the ITS2 sequences of A. lancea. The maximum K2P intraspecific genetic distances of both A. japonica and A. coreana were 0.013. The maximum K2P intraspecific genetic distances of A. macrocephala, A. lancea, A. japonica and A. coreana were less than the minimum interspecific genetic distance of adulterants. The ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. DNA barcoding could be used as a fast and accurate identification method to distinguish Atractylodis Macrocephalae Rhizoma, Atractylodis Rhizoma, from their adulterants to ensure its safe use.
