Human nerve growth factor (NGF) is a nerve cell growth regulation factor, which can provide nutrition for the neurons and promote the neurites outgrowth. In order to produce large-scale recombinant human nerve growth factor (rh-beta-NGF), we constructed a plasmid vector, which can stably express the rh-beta-NGF in the HEK293 cell lines. First, the plasmid of pCMV-beta-NGF-IRES-dhfr was constructed and transformed into HEK293 cells. Then MTX pressurized filter and limiting dilution methods were used to obtain monoclonal HEK293 cell lines. After stepwise reducing serum in culture media, the cells eventually adapted to serum-free medium and secreted rh-beta-NGF. SDS-PAGE analysis revealed that the expression product owned a molecular weight of about 13 kDa and a purity of more than 50%. The peptide mapping sequencing analysis demonstrated the sequences of rh-beta-NGF matched with the theoretical ones. Later we purified this protein by ion exchange and molecular sieve chromatograph. Finally, our experimental results exhibited that the recombinant cell lines can stably express rh-beta-NGF with a high efficiency of more than 20 pg/cell x day. In addition, this protein could successfully induce differentiation of PC12 cells. In summary, our recombinant HEK293 cells can express bio-active rh-beta-NGF with great efficiency and stability, which supply a valid basis to large-scale production of rh-beta-NGF.

Methods According to the criteria of KBD diagnose (WS/T 207-2010), 111 cases of patients were taken X-ray films of right hands. Joint space narrow, joint deformity, subchondral sclerosis, osteophyte, coarse and irregularity of joint, marginal retraction sign and capsule changes were chosen as the descriptive indexes, and these indexes were analyzed with SPSS 17.0. Results A total of 111 cases adult patients with KBD were examined right hand by X-ray, abnormality on X-ray film were 103 cases, the abnormal rate was 92.79%. The most affected fingers were Ⅱ- Ⅳphalanx bones, Ⅱphalanx bones accounted for about 92.23% (95/103), Ⅲ phalanx bones accounted for about 99.03% (102/103), and Ⅳ phalanx bones accounted for about 99.03% (102/103). There was significant difference of the abnormality between th e proximal phalanx and the middle phalanx among the Ⅱ - Ⅳ phalanx bones(χ2=79.33, P<0.05). Abnormal numbers of joint deformity, marginal retraction sign, coarse and irregularity of joint, osteophyte, capsule changes and joint space narrow in the proximal phalanx were 212, 7, 134, 47, 15 and 115 in Ⅱ - Ⅳ proximal phalanx, respectively; while the abnormal numbers of joint deformity, marginal retraction sign, coarse and irregularity of joint, osteophyte, capsule changes and joint space narrow in the middle phalanx were 77, 37, 137, 26, 19 and 126 in Ⅱ - Ⅳmiddle phalanx, respectively. Conclusion The Ⅱ - Ⅳ phalanx bones of right hand are the most affected locations in adult KBD.

Objective: To investigates the role of piwi-interacting RNAs (piRNA) in the occurrence and development of hepatocellular carcinoma. Methods: Second-generation small RNA sequencing was performed on cancer and paracancerous tissues, metastatic and non-metastatic liver cancer tissues of patients with liver cancer, and the sequencing data were filtered out for the common RNA sequences to be repeated. The piRNA predictor was used to forecast the possible new piRNA merged with the downloaded known piRNA to screen out distinction. A miRanda algorithm was used to predict the corresponding target genes and functional enrichment analysis. piRNA was selected for experimental functional (migration) analysis. An independent t-test was used to compare means between the two groups. Results: 66 772 piRNAs (known 149) were obtained by sequencing. 241 piRNAs were found in cancer and paracancerous tissues, and 1 634 piRNAs were found in metastatic and non-metastatic tumors. Analysis of the GO and KEGG pathways of the target genes of differential piRNAs revealed that they were mainly involved in cell adhesion. An experimental functional analysis was performed on the selected Pirna (PIR1/97), which showed that it promoted the migration of hepatoma cells (LM3: t = 8.829, P < 0.05; PLC: t = 7.318, P < 0.05). Conclusion The expression levels of piRNA in hepatocellular carcinoma patients with cancer and paracancerous tissues, metastasis and non-metastatic liver cancer tissues are different and it could be entailed in the metastasis process of hepatocellular carcinoma. Hence, experimental functional analysis is required for research and experimental confirmation.

Objective To investigate the changes of sex hormone and androgen receptor levels and evaluate the relationship of the sex hormones and androgen receptor with coronary heart disease (CHD) in elderly men. Methods A cross-sectional study was performed in 539 elderly men, including 400 healthy people aged 62-92 years and 139 CHD patients aged 60-88 years. The plasma concentrations of total testosterone (TT), free testosterone (FT), dehydroepiandrosterone sulfate (DHEAS), sex hormone binding globulin (SHBG), estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were measured. The androgen receptor (AR) level was tested by flow cytometry. Results The fluorescence intensity of DHEAS, TT, SHBG, FT and AR were significantly lower in CHD group than in healthy group (P<0.01);however, FSH and E2 in CHD group were higher(P(0.01). Age was negatively correlated with TT(r=-0.28,P<0.01) and FT (r=-0.17,P<0.05), and positively correlated with SHBG(r=0.14,P<0.05) and E2 (r=0.33, P<0.01). AR fluorescence intensity was negatively correlated with systolic blood pressure (r=-0.12,P<0.01). Logistic regression analysis indicated that TT (OR=1.065,9% CI: 1.012～1.121,P<0.05), SHBG(OR=0.994,95% CI:0.990～0.998,P<0.01) and AR (OR=0.971,95%CI:0.956～0.986, P<0.01)were significantly associated with CHD in elderly male patients. Conclusions The levels of DHEAS, TT, SHBG, FT and AR are lower in elderly men with CHD than in elderly healthy men;however, the FSH and E2 concentrations are higher. Low levels of TT, SHBG and AR may be the independent risk factors for CHD in elderly men.

Objective: To investigate the influence of pharmaceutical care pathway on cancer-related fatigue (CRF) and negative emotion in patients with advanced lung cancer undergoing chemotherapy. Methods: Patients with advanced lung cancer admitted to the oncology department of Yongkang first people′s hospital from January 2017 to June 2018 for chemotherapy were randomly divided into two groups:61 cases received conventional clinical pathway management (control group), and 64 cases received conventional clinical pathway combined with pharmaceutical pathway management (intervention group). Fatigue, anxiety, depression scores were compared between the two groups before and after 2, 4 cycles chemotherapy. Results: There was no significant difference in baseline condition between the two groups (P>0.05). After 4 cycles of chemotherapy, emotional, physical and cognitive fatigue scores in the intervention group were lower than control group (t=2.975, 1.512, 2.393, P<0.05). With the increase of chemotherapy cycles, scores of fatigue dimensions in control group were increased (F=44.274,21.740,29.261,7.206, P<0.05). In the intervention group, there were statistically significant differences in scores of fatigue dimensions (F=17.083, 15.902, 17.055, 10.543, P<0.01), among which, scores of behavioral and physical fatigue dimensions were increased (P<0.01), while scores of emotional and cognitive fatigue dimensions were decreased (P<0.01). In terms of negative emotions, depression scores in the intervention group were lower than those in control group at 2 cycles of chemotherapy (t=2.578, P<0.05), and at 4 cycles, anxiety and depression scores were lower than control group (t=7.004, 7.454, P<0.05). As the chemotherapy cycle increased, anxiety and depression scores in the control group increased (F=12.333, 14.819, P<0.05), while those in the intervention group decreased (F=4.992, 3.826, P<0.05). Conclusion The pathway of clinical pharmaceutical care can significantly improve the CRF and negative emotions of patients with advanced lung cancer undergoing chemotherapy.
