Objective: To analyze the features and patterns of acupoint selection in acupuncture-moxibustion treatment of chronic atrophic gastritis (CAG) by data mining technique. Methods:Relevant clinical studies published before 25 June, 2017 were searched in databases including PubMed, EMBASE, Cochrane library, Chinese Biomedical Literature Database (CBM), China National Knowledge infrastructure (CNKI), and Wanfang Academic Journal Full-text Database (Wanfang). Results:A total of 122 papers were included, involving 69 points. It was found that the top three points on the frequency list were Zusanli (ST 36), Zhongwan (CV 12) and Weishu (BL 21). The points selected were distributed in 11 meridians, in which the Stomach Meridian of Foot Yangming, Conception Vessel, and Bladder Meridian of Foot Taiyang ranked the top and accounted for 74.0％ of the total frequency. Of the involved specific points, Five Shu-Transmitting points, crossing points and Back-Shu points ranked the top, accounting for 47.1％. The analysis of association pattern has shown that Zusanli (ST 36) and Zhongwan (CV 12) won the highest support rate in the paired groups; Zusanli (ST 36), Weishu (BL 21) and Zhongwan (CV 12) had the highest support rate among the point groups. The Five Shu-Transmitting points and the Lower He-Sea points had the highest support rate among the specific point groups. Conclusion: The data mining results of the studies on acupuncture-moxibustion for CAG are substantially in line with the acupuncture-moxibustion treatment theories in traditional Chinese medicine. The results can reflect the acupoint selection patterns in treatment of CAG and provide reference for acupuncture-moxibustion treatment of CAG in clinic.

OBJECTIVETo explore the mechanism of occupational medicamentosa-like dermatitis (OMDT) induced by trichloroethylene (TCE) and some immunity indexes in workers occupationally exposed to TCE.

METHODSThe blood samples from 8 cases with medicamentosa-like dermatitis in 1st, 2nd, 3rd, 4th and 5th weeks after admitting to hospital were examined for liver function, immunoglobulin and some complement indexes. Thirty nine workers occupationally exposed to TCE were investigated for urinary TCE and some immuno-complement indexes. The TCE concentrations of air in workplaces were monitored.

RESULTSC3d-CIC and C3 of patients before admission were (92.86 ± 44.80) mg/L and 0.91 ± 0.19 mg/L, respectively. C3d-CIC and C3 of patients before discharge were (52.41 ± 17.75) mg/L and (1.14 ± 0.22) mg/L, respectively. There were significant differences between admission and discharge (P < 0.05). The average TCE concentration in 4 workplaces was (351.96 ± 36.72) mg/m(3), which was higher than the occupational exposure limits (OELs). The number of workers exposed to the TCE concentration-time weighted and TCA in urine over OELs were 28.21% and 56.41% of total subjects, respectively. The serum IgG and CIC levels of patients before discharge were (10.03 ± 1.21) mg/L and 103.50 ± 29.17 mU/L, which were significantly lower than those (17.21 ± 1.85) mg/L and (227.46 ± 111.67) mU/L of patients before admission (P < 0.01).

CONCLUSIONThe type II and III hypersensitivity may be associated with OMDT and the organ injure induced by TCE.

Based on the deletion information of high virulent PRRSV genome, 3 oligonucleotide primer were designed and synthesized. Specific and sensitive reverse transcription-PCR (RT-PCR) assays were de-veloped for the detection of high virulent PRRSV. The sensitivity and specificity of RT-PCR assays were evaluated, the results showing that the detection limit of the assay was found to be 0.265 pg of tissue total RNA, and the protocol have no cross-reaction with classical swine fever virus, porcine circovirus type 2,pseudorabies virus, streptococcus, haemophilus parasuis and Escherichia coli. Then 36 cell cultures, two PRRSV live vaccine strains and 184 clinical specimens from 52 farms were tested. Five PRRSV field iso-lates were the high virulent PRRSV; two PRRSV live vaccine strains from normal PRRSV, and 123 speci-mens from 42 farmer were positive (only 1 specimen was normal PRRSV). This RT-PCR method proved to be accurate differential diagnosis of the high virulent PRRSV and normal PRRSV with the characteristics of rapidity, sensitivity and specificity, and has a strong clinical relevance.

OBJECTIVETo develop a targeting protein for Xenopus kinesin-like protein 2 (TPX2) C' terminal SBP-3 x Flag-tagged HCT 116 cell model.

METHODSHomologous arms were amplified by polymerase chain reaction (PCR), and then the adeno-associated virus (AAV) -targeting vector of TPX2 was constructed. HCT 116 cells were targeted after the viruses were packaged. Positive cell clones with neomycin resistance gene were obtained by G418 and PCR screening. Finally, the neomycin gene cassette was excised after the targeted clones were infected with adenovirus expressing Cre-recombinase, and the TPX2 C' terminal SBP and 3 x Flag endogenous double-tagged HCT 116 cells were obtained by PCR screening.

RESULTSTwo positive cell clones with neomycin resistance gene were obtained by PCR screening. The positive clones with neomycin resistance gene excised were obtained by Cre adenovirus infection, and the knock-in of SBP-3 x Flag gene was verified by Western blot analysis.

Objective To measure the body fat parameters of adult population in Guangxi, and to explore the characteristics of distribution of fat content with age and gender. Methods A total of 1558 male residents and 2132 female residents were selected by random sampling method . The subjects were divided into 8 groups every 10 years, and the fat parameters were measured and recorded by body composition analyzer. The statistical software SPSS 22. 0 analysed data. Results The total of fat mass and fat content of all parts as well as the subcutaneous and limb fat content of all age groups in Guangxi females were higher than that of the male. The fat content of each part of the male increased first and then decreased with age. It was at the age of 30 that the fat parameters of the male peaked with the highest rates of overweight and obesity. Males had more visceral fat and trunk fat than women at 30-40 years old, and showed predominantly centripetal obesity.Total fat content and fat content of all age groups of female showed a rapid rise at the age of 20-50, and reached a peak at 40 years old. After 50 years old, they slowly decreased and gradually stabilized. The main manifestations of young women were subcutaneous and limb fat increase, which was mainly characterized by centripetal obesity after 40-50 years old, when the rates of overweight and obesity were the highest. Conclusion The body fat content of male and female people in Guangxi increases first and then decreases with age. Twenty-thirty years old of Males and 20-50 years old of female are the key time points for the change of body fat content. In addition of the visceral and trunk fat content, the fat content of different age groups and different parts of female is higher in Guangxi than that of males. The visceral and trunk fat content of Guangxi young adults male is higher than that of females.

Objective To explore the influence of muscle and fat distribution on sit-up ability of female college students. Methods A total of 1560 female students majoring in non-physical education in a Guangxi University were randomly selected. Body composition was measured by the bioresistance antibody component meter. According to the National Physical Health Test Standard, the height, weight and sit-ups of female college students were measured. The students were divided into four groups according to the score of sit-ups:<60 points, 60-69 points, 70-79 points, ≥80 points. SPSS 22.0 statistical software was used to analyze the data. Results There were statistically significant differences in body fat rate, total fat mass, trunk fat mass, trunk fat rate, visceral fat area, visceral fat mass and subcutaneous fat mass in different sit-ups (F value were 3.414, 2.914, 2.881, 3.347, 3.064, 3.235, 2.766, P<0.05). That was, the fat parameters in the 60-69 group were the highest and ≥80 the lowest. However, there was no significant difference between total muscle mass and trunk muscle mass in each score segment. After correcting for age, height, and weight factors, except for visceral fat area and visceral fat mass, the correlation between other fat parameters and sit-up score were negatively correlated, which were statistically significant (r<0, P<0.05). There was a positive correlation between each muscle parameter and sit-up performance (r>0, P<0.05). Compared with other parameters, the correlation coefficient between trunk muscle mass and sit-ups was the largest. Conclusion The distribution of fat and muscle has different effects on sit-up ability. Female college students' sit-up ability is greatly affected by subcutaneous fat and trunk muscle, and has nothing to do with visceral fat.

OBJECTIVE: To study the long-term clinical effect of multicenter multidisciplinary treatment (MDT) in children with renal malignant tumors. METHODS: A retrospective analysis was performed on the medical data of 55 children with renal malignant tumors who were diagnosed and treated with MDT in 3 hospitals in Hunan Province from January 2015 to January 2020, with GD-WT-2010 and CCCG-WT-2016 for treatment regimens. A Kaplan-Meier survival analysis was used to analyze the survival of the children. RESULTS: Of the 55 children, 10 had stage I tumor, 14 had stage Ⅱ tumor, 22 had stage Ⅲ tumor, 7 had stage IV tumor, and 2 had stage V tumor. As for pathological type, 47 had FH type and 8 had UFH type. All children underwent complete tumor resection. Of the 55 children, 14 (25%) received preoperative chemotherapy. All children, except 1 child with renal cell carcinoma, received postoperative chemotherapy. Among the 31 children with indication for radiotherapy, 21 (68%) received postoperative radiotherapy. One child died of postoperative metastasis. The incidence rate of FH-type myelosuppression was 94.4%, and the incidence rate of UFH-type myelosuppression was 100%. The median follow-up time was 21 months and the median survival time was 26 months for all children, with an overall survival rate of 98% and an event-free survival rate of 95%. CONCLUSIONS Multicenter MDT has the advantages of high success rate of operation and good therapeutic effect of chemotherapy in the treatment of children with renal malignant tumors, with myelosuppression as the most common side effects, and radiotherapy is safe and effective with few adverse events. Therefore, MDT has good feasibility, safety, and economy.

Objective: To analyze the efficacy of sinonasal adenoid cystic carcinoma (ACC) with perineural invasion (PNI), and explore the prognostic value of PNI on sinonasal adenoid cystic carcinoma. Methods: The clinical data of 105 patients with sinonasal ACC admitted to Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2016 were retrospectively reviewed. All patients were restaged according to American Joint Committee on Cancer 8th edition. Follow-up visits were conducted to obtain information of treatment failure and survival outcome. The Log rank test was used for univariate analysis of prognostic factors, and Cox regression model was used for multivariate prognostic analysis. Results: The maxillary sinus (n=59) was the most common primary site, followed by the nasal cavity (n=38). There were 93 patients with stage Ⅲ-Ⅳ. The treatment modalities included surgery alone (n=14), radiotherapy alone (n=13), preoperative radiotherapy plus surgery (n=10), and surgery plus postoperative radiotherapy (n=68). The median follow-up time was 91.8 months, the 5-year local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates were 72.6%, 73.0%, 52.9% and 78.0%, respectively. There were 33 patients (31.4%) with PNI-positive. The 5-year DMFS, PFS, and OS rates of PNI-positive group were 53.7%, 29.4% and 56.5%, respectively, which were significantly inferior to those of PNI-negative group (80.8%, 63.0% and 86.8%, respectively, P<0.05), while there was no significant difference in the 5-year LC rate between both groups (64.5% vs 76.5%, P=0.273). The multivariate Cox regression analysis showed PNI was one of the poor prognostic factors of DMFS (HR=3.514, 95%CI: 1.557-7.932), PFS (HR=2.562, 95%CI: 1.349-4.866) and OS (HR=2.605, 95%CI: 1.169-5.806). Among patients with PNI-positive, the 5-year LC, PFS and OS rates of patients received surgery combined with radiotherapy were 84.9%, 41.3% and 72.7%, respectively, which were significantly higher than 23.3%, 10.0% and 26.7% of patients receiving surgery or radiotherapy alone (P<0.05). Conclusion: The presence of PNI increases the risk of distant metastasis in patients with sinonasal ACC. Compared with patients with PNI-negative, the prognosis of patients with PNI-positive is relatively poor, and surgery combined with radiotherapy for PNI-positive sinonasal ACC results in good clinical outcomes.

Objective: To evaluate the long-term outcomes, failure patterns and prognostic factors of definitive radiotherapy in patients with cervical esophageal carcinoma (CEC). Methods: We retrospectively reviewed the clinical data of 148 CEC patients who treated with definitive radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2001 to December 2017. The median radiation dose was 66 Gy (59.4-70 Gy) and 33.1% of patients received concurrent chemotherapy. The Kaplan-Meier method was used to calculate survival rates. The log rank test was used for survival comparison and univariate prognostic analysis. The Cox model was used for multivariate prognostic analysis. Results: The median follow-up time was 102.6 months. The median survival time, 2- and 5-year overall survival (OS) were 22.7 months, 49.9% and 28.3%. The median, 2- and 5-year progression-free survival were 12.6 months, 35.8% and 25.8%. The 2- and 5-year locoregional recurrence-free survival were 59.1% and 50.8%. The 2- and 5-year distant metastases-free survival were 74.6% and 65.9%. Multivariate analysis showed that EQD(2)>66 Gy was the only independent prognostic indicator for OS (P=0.040). The median survival time and 5-year OS rate significantly improved in patients who received EQD(2)>66 Gy than those who received≤66 Gy (31.2 months vs. 19.2 months, 40.1% vs. 19.1%, P=0.027). A total of 87 patients (58.8%) developed tumor progression. There were 50 (33.8%), 23 (15.5%) and 39 (26.4%) patients developed local, regional recurrence and distant metastases, respectively. Eleven patients (7.4%) underwent salvage surgery, and the laryngeal preservation rate for entire group was 93.9%. Conclusions: Definitive radiotherapy is an effective treatment for cervical esophageal carcinoma with the advantage of larynx preservation. Local recurrence is the major failure pattern. EQD(2)>66 Gy is associated with the improved overall survival.
