OBJECTIVETo understand the comorbid characteristics and distribution of combined treatment of Chinese and Western medicine in depressive patients.

METHODThe descriptive statistic method and association rule were used to analyze the data from 19 general hospitals with 3-A level in China.

RESULTAmong the depressive disorder, the most frequent co-morbid physical diseases included hypertension (24.67%), coronary heart disease (16.10%) and cerebral infarction (12.89%), and the proportion of comorbid changes with the increasing age, from 6.51% to 12.55%, 16.33% and 12.47% for hypertension; from 2.79% to 5.69%, 10.17% and 14.22% for coronary heart disease; from 3.72%, 6.27%, 7.70% and 12.25% for cerebral infarction. The use frequency of the antidepressants is 77.18%, and the use frequency of flupentixol & melitracen is 20.95%. The use frequency of Huoxue Huayu Tongluo of traditional Chinese medicine is 59.97%, with that of 27.91% for Ginkgo biloba extract The combined use frequency of Huoxue Huayu Tongluo of TCM and the antidepressants is the highest, especially for the combined use of Shuxuening injection and fluoxetine.

CONCLUSIONThe most frequent comorbid diseases of depression include three kinds of diseases, such as hypertension, coronary heart disease and cerebral infarction, and its proportion gradually increased with the growth of age. The single use frequency of flupentixol & melitracen and G. biloba extract is the highest, while the combined use of Shuxuening injection and fluoxetine is the highest.

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.

OBJECTIVETo explore the repair of Xiangsha Liujunzi Decoction (XSLJZD) on interstitial cells of Cajal (ICC) and gap junction (GJ) in the gastric muscular layer of rats of Pi-qi deficiency syn- drome (PQDS).

METHODSPQDS was established using purgative method with bitter and cold drugs in 30 healthy Wistar rats. After successful modeling they were randomly divided into the treatment group and the model group, 15 in each group. Another 15 healthy Wistar rats were recruited as the healthy control group. Rats in the treatment group were gastric administered with XSLJZD at 2 mL/100 g body weight, once daily for 14 successive days. Equal volume of normal saline was gastrically administered to those in the healthy control group and the model group. The gastric muscle tissues were taken out before modeling, before intervention, and after intervention, respectively. Ultrastructural changes of ICC and GJ were observed using transmission electron microscope (TEM). The number and distribution of Connexin43 (Cx43) were detected using immunohistochemistry.

RESULTSResults of TEM indicated that compared with the healthy control group, both ICC and GJ in the model group showed obvious injury. ICC and GJ were apparently repaired after intervention in the treatment group. Compared with the same group before modeling, the integrated optical density (IOD) of the Cx43 expression significantly decreased in the model group before and after intervention (P <0.05). Compared with before intervention, the IOD of the Cx43 expression significantly increased in the treatment group (P <0.05). Compared with the healthy control group, the IOD of the Cx43 expression significantly decreased in the model group before and after intervention (P <0.05). Compared with the model group, the IOD of the Cx43 expression significantly increased in the treatment group (P <0.05).

CONCLUSIONSUltrastructures of ICC and GJ in the gastric muscular layer of rats of PQDS were obviously damaged. XSLJZD could repair the structural damage of ICC and GJ in the gastric muscle tissues of rats of PQDS.

OBJECTIVE CYP2 family including CYP2C and CYP2J is the predominant arachidonic acid (AA) epoxygenase, and the epoxidation of AA produces four regioisomeric cis-epoxyeicosatrienoic acids (5,6-, 8,9-, 11,12-, and 14,15-EET). Human CYP2J2 is one of the main CYP isoforms expressed in brain, but CYP2C8 was present at a low level. The aim of this study is to investigate the roles of brain CYP2J in Parkinson disease. METHODS Rats received the right-unilaterally injection with concentrated LV-CYP2J3 or LV-EGFP in the substantia nigra (SN) at 3 d before LPS or 6-OHDA treatment. The animals were tested for rotational behavior with the dopaminergic agonist apomorphine dissolved in sterile saline at 14 and 21 d after LPS injection. The influence of CYP2J-dependent derivative, 14,15-EET, on the genes related with oxidative stress was assayed in SH-SY5Y cells. RESULTS CYP2J overexpression or 14,15-EET treatment significantly increased the levels of SOD1, CAT, GPX1, NRF2 and KEAP1 in neurons. TLR4- MyD88 signaling pathway was involved the down- regulation of CYP2J by LPS. The binding of p-CREB with the promoter of CYP2J was inhibited by the LPS treatment. The loss of dopami?nergic neurons in the right SN induced by LPS or 6- OHDA was significantly decreased by CYP2J3 transfection at 21 d after LPS injection. Compared with LPS or 6-OHDA group, the number of the rotation of rats was decreased by 42.6% and 60.7% by CYP2J3 transfection at 14 d after LPS or 6-OHDA injection;meanwhile, the rotation number was decreased by 12.7% and 21.3% at 21 d. The accumulation of alpha synuclein induced by LPS was significantly decreased by CYP2J3 transfection. The mRNA levels of SOD1, CAT, GPX1, NRF2 and KEAP1 in SN were decreased by LPS, which was attenuated by the injection of LV-CYP2J3. CONCLUSION Brain CYP2J can play a protective role in the damage of the inflammation and oxidative stress to the dopaminergic neurons. Brain CYP2J- dependent derivatives from AA may have therapeutic effects in Parkinson disease via the up- regulation of the antioxidant system in neurons.

OBJECTIVETo investigate the prevalence of chronic obstructive pulmonary disease (COPD) and its risk factors in population over 40 years old in northern part of Guangdong province.

METHODSUsing uniform scheme, procedures and questionnaire, a cluster-randomized-sampling survey for the population aged over 40 years in a rural area of Shaoguan in the northern part of Guangdong province was performed. Spirometry was performed for every participant, followed by a bronchodilatation test when bronchial obstruction was present.

RESULTSThere were 1468 cases with complete data from 1498 people aged >or= 40 years including 640 males, 828 females with an average age of 54.3 years old. The total prevalence of COPD was 12.0%. The prevalence of COPD in males was significantly higher than that in females (18.3% vs. 7.1%, P < 0.01). Only 80.7% of the patients with COPD presented one or more symptoms as cough, phlegm, or dyspnoea. Underdiagnosis of COPD would be quite serious. Only 26.1% of the cases was previously diagnosed to have chronic bronchitis, emphysema, or COPD. Smoking was an important risk factor to COPD and 78.4% of the patients with COPD were smokers. However, relation of biomass and COPD called for further investigation.

CONCLUSIONPrevalence of COPD was much higher than expected in the northern part of Guangdong while smoking was an most important risk factor of COPD. Lung function test seemed to be of great importance to COPD diagnosis, especially in the earlier period of COPD.

OBJECTIVETo explore the impact of previous abdominal operations on the outcome of laparoscopy-assisted radical total gastrectomy (LATG).

METHODSClinical data of 328 patients with gastric cancer who underwent LATG from January 2008 to December 2010 were analyzed retrospectively. Among the patients, 57 cases had previous abdominal surgeries (PAS group) and 271 cases had no previous abdominal surgeries (NPAS group). The intraoperative and postoperative parameters were compared, and risk factors associated with postoperative complications were analyzed using univariate and multivariate analysis.

RESULTSThere was no significant difference between the two groups in the mean number of lymph nodes harvested (30.2±10.5 vs. 31.1±9.4, P>0.05). The operative time [(247.0±60.5) min vs. (214.7±57.0) min, P<0.01] and the postoperative complication rate [21.1%(12/57) vs. 11.1%(30/271), P<0.05] were significantly different between the two groups. However, there were no differences in intraoperative blood loss, transfused patients, conversion, postoperative ambulation time, postoperative flatus passage time, resumption of liquid diet, removal of gastric tube, and postoperative hospital stay (all P>0.05). Multivariate logistic regression analysis showed that previous abdominal surgeries was not an independent risk factor associated with postoperative complication morbidity (P>0.05).

CONCLUSIONSLATG is feasible for gastric cancer patients who has previous abdominal surgeries. Previous abdominal surgery may prolong operative time but is not an independent risk factor associated with postoperative complication.

Objective To investigate the presentationand significance of circulating autoantibodies to erythropoietin receptor (EPOR) in sera from patients with systemic lupus erythematosus (SLE). Methods One hundred and twenty-four consecutive patients with SLE, seven with autoimmune hemolytic anemia (AIHA), 19 patients with iron deficiency anemia (IDA) and 45 normal individuals were involved in this study. In all patients with SLE, the disease activity was evaluated using the European consensus Lupus Activity Measurement scale. Antibodies to EPOR were detected by enzyme-linked immunosorbent assay (ELISA). All data were tested with Chi-squared or Student's t tests by SPSS software. Results A higher frequency of antibodies to EPOR were detected in SLE patients than healthy controls (20.2% vs 2.2%, P=0.004), however, they could not be detected in AIHA and IDA patients. Moreover, anti-EPOR antibodies were detected in 17 (33.3%) of 51 SLE patients with anemia, compared with that in 8 (11.0%, P=0.002) of 73 patients without anemia. Furthermore, patients with antibodies to EPOR had more severe anemia and often presented as microcytic anemia (P =0.005) than those without anti-EPOR antibodies. Finally, anti-EPOR antibodies seemed to be more likely to occur in patients with skin rash (P=0.014), low levels of C3 component of complement (P=0.01), positive anti-dsDNA antibodies (P=0.000) and higher disease activity scores (P= 0.024). Conclusion The higher incidence of antibodies to EPOR in SLE patients with anemia suggest that anti-EPOR antibodies might play a vital role in the development of anemia in SLE patients. Thus, detecting anti-EPOR antibodies in SLE patients with anemia may be helpful.

OBJECTIVETo study the effect of aluminume adjuvant and immunization schedule on immunogenicity of Sabin inactivated poliovirus vaccine.

METHODSFour batches of Sabin IPV were produced by different concentrations of type 1, 2, and 3 poliovirus and administrated on three-dose schedule at 0, 1, 2 months and 0, 2, 4 months on rats. Serum samples were collected one month after each dose and neutralizing antibody titers against three types poliovirus were determined by micro-neutralization assay.

RESULTSThe GMTs of neutralizing antibodies against three types poliovirus increased significantly and the seropositivity rates were 100% in all groups after 3 doses. There was no significant difference between two immunization schedules, and the 0, 2, 4 month schedule could induce higher level neutralizing antibody compared to the 0, 1, 2 month schedule. The groups with aluminum adjuvant could induce higher level neutralizing antibody compared to the groups without adjuvant.

CONCLUSIONAluminum djuvant and immunization schedule could improve the immunogenicity of Sabin IPV.

This study was purposed to investigate the mechanism of thrombocytopenia in patients with systemic lupus erythematosus (SLE) through detecting anti-megakaryocyte antibodies in SLE patients. The serum anti-megakaryocyte antibodies in 36 SLE cases with thrombocytopenia were detected by using indirect immunofluorescence, the detected results were compared with detected results of 30 SLE cases without thrombocytopenia and 30 healthy persons. The results showed that the positive incidences of anti-megakaryocyte antibody in serum of 36 SLE cases with thrombocytopenia, 30 SLE cases without thrombocytopenia and 30 healthy persons were 19.4% (7/36), 6.7% (2/30) and 3.3% (1/30) respectively. As compared with SLE patients without thrombocytopenia and healthy persons, SLE patients with thrombocytopenia had higher incidence of anti-megakaryocyte antibodies, moreover there was significant difference between SLE patients with thrombocytopenia and healthy persons (p < 0.05), while there was no significant difference between SLE patients with or without thrombocytopenia (p > 0.05). It is concluded that autoantibodies against megakaryocytes exist in SLE patients and may partially contribute to the incidence of thrombocytopenia in SLE patients. The detection of anti-megakaryocyte antibodies with a enough case number is needed to make a final conclusion on thrombocytopenia pathogenesis in SLE.

OBJECTIVETo report and study a case of sporadic family fatal insomnia (SFFI) on its.

METHODSInvestigate clinical characteristics and family disease history of a suspect FFI patient. His clinical characteristic was analyzed, he and his 14 family members genomic DNA was extracted by standard techniques from their and blood detected with polymerase chain reaction (PCR) method and DNA sequencing to find out his prion protein (PrP) gene mutation. The patient's CSF was detected with Western-Blot method for 14-3-3 brain protein.

RESULTSThe patient was diagnosed as an sporadic FFI by his developed sleep disturbance and changes in sleep-awake rhythm, motor abnormalities, mental disorder, dementia, autonomic dysfunction; his family history; his 14-3-3 brain protein-positive (CSF) and analysis results of his PrP gene (codon point mutation D178N and methionine homozygosity at position 129M/M). Suggesting that in the future to identify CJD and FFI patients, screening should focus on clinical symptoms and laboratory results. The PrP gene of 14 family members did not appear Mutation, and there is no person suffering from the same disease.

CONCLUSIONSThe case was diagnosed as a sporadic familial fatal insomnia. Analysis of suspicious patients' genomic DNA for PrP gene mutation might be very important for FFI diagnosis because there exist many difficulties in clinical laboratory evaluation. This patient might be the first SFFI patient reported in China and the case finding might have momentousness in clinical and basical study.
