Single cell RNA sequencing (scRNA-seq) is an advanced technology to study the transcriptome information at the single cell level. The application of this technology can attribute to analyze the heterogeneous map of cells in the process of disease development, and precisely identify the specific cell subsets that are responsive to pharmacological therapy. Currently, scRNA-seq technology has been widely applied in the field of drug research, including studies on therapeutic targets, drug-induced adverse reactions, drug resistance and vaccine. This work reviews the application of scRNA-seq technology in drug discovery, which offers a scientific basis for personalized and accurate medication therapy.

Purpose To investigate the clinicopathologic features of desmoplastic fibroma of bone (DF).Methods The clinical and pathologic profiles of 7 cases were retrospectively analyzed.Results Desmoplastic fibroma of bone was a rare neoplasm of bone,which typically occurred in young children and adolescents.The tumor showed infiltrative and locally aggressive nature,the most common sites were long tubular bones and mandible.Microscopically,the tumor was composed of sparse fibroblasts in a rich background of collagen fibers.Immunohistochemically,the tumor cells were positive for vimentin and SMA.Conclusion Desmoplastic fibroma is a rare,locally aggressive fibroblasticlesion of bone.It can make an accurate diagnosis by integrating the clinical location with histopathological features.Trauma,hormone and horomosome aberration may be related with its pathogenesis.

Objective:To study the influence of Wnt5a gene silence on the proliferation,migration and invasion of lung squamous carcinoma cells.Methods:A recombinant plasmid pHI-siRNA~(Wnt5a-)was constructed and used to deliver small interference RNA (siRNA)targeting Wnt5a in SK-MES-1 cells;the transfected cells were screened to establish a stable transgenic cell line.MTT,cell cycle and Transwell assays were employed to evaluate the effect of Wnt5a gene silence on the proliferation,migration and invasion of lung squamous carcinoma cells.Results:Western blotting assay revealed that Wnt5a was lowly expressed in SK-MES-1~(Wnt5a-)(13.6%).The proliferation index(PI)of transgenic cell line was slightly lower than that of the control cell line([28.3?3.8]% vs[30.5?5.2]%). The migration and invasion capabilities of SK-MES-1~(Wnt5a-)cells were(47.3?9.2)% and(39.7?11.7)% of the control cells, respectively.Conclusion:Low Wnt5a expression can significantly inhibit the migration and invasion capabilities of SK-MES-1 cells, indicating that Wnt5a might be a potential target for gene therapy of lung squamous carcinoma.

This study was aimed to evaluate the feasibility of wind-warm lung-heat disease (non-severe community-acquired pneumonia, CAP) from the clinical curative effect, hospitalization days, medical expenses and other aspects. This study selected 198 wind-warm lung-heat disease (non-severe CAP) inpatients from January, 2012 to December, 2012 with the conventional therapy in the Respiratory Department, Wuhan Integrated Traditional Chinese Medicine (TCM) & Western Medicine Hospital as the control group. And another 179 wind-warm lung-heat disease (non-severe CAP) inpatients were selected from January, 2013 to December, 2013 with the TCM clinical pathway treatment in the Respiratory Department of the same hospital as the treatment group. Retrospective analysis was used to compare the clinical curative effects, hospitalization days, and medical cost differences. The results showed that TCM clinical pathway for wind-warm lung-heat disease (non-severe CAP) can shorten the hospitalization days and reduce patients’ medical costs, and ensure the clinical curative effects. It was concluded that the standardized TCM clinical pathway had positive effect on wind-warm lung-heat disease (non-severe CAP). Therefore, the formulation and implementation of TCM clinical pathway was of great significance in the treatment of wind-warm lung-heat disease (non-severe CAP).

Objective To investigate the effect of fatty acid binding protein 4(FABP4)DNA methylation on abnormal lipid metabolism in placental trophoblastic dyslipidemia. Methods Human placental trophoblast cell line(HTR-8)was treated with L-NAME of 100 μmol/L for 48 h. The lipid content in placental trophoblasts was detected by chemical enzyme-colorimetry. The FABP4 DNA methylation level in placenta trophoblasts was detected by nested-touch down methylation specific PCR (NT-MSP). the mRNA and protein expression of DNMT1 and FABP4 were detected by qRT-PCR and Western Blot,respectively,in trophoblast cells. Results The lipid content in trophoblasts significantly increased as compared with the control(P < 0.05). Expression of FABP4 mRNA and protein increased(P < 0.05),while FABP4 methylation level and expression of DNMT1 significantly decreased (P<0.05)after treatment with L-NAME. Conclusions FABP4 DNA methylation is involved in the regulation of lipid metabolism in placental trophoblastic cells of hypertensive disorder complicating pregnancy.

OBJECTIVETo study curative effect of chronical hepatitis B with treatment of integrative traditional Chinese and western medicine.

METHOD115 cases of HBeAg and/or HBVDNA positive chronical hepatitis B were randomly divided into two groups in control. The first group treated by traditional Chinese medicine (TCM)-Fufang Huangqi granule and the second treated by intergrative traditional Chinese and western medicine (ICWM)-Fufang Huangqi granule and lamivudine for at least 24 weeks.

RESULTThe positive rate of HBVDNA at 12, 24 weeks, and the positive rate of HBeAg at 24 weeks in TCM are markedly lower than those of before treatment (P < 0.01). The positive rate of HBeAg and the positive rate of HBVDNA in ICWM are markedly lower than those of before treatment both at 12, 24 weeks (P < 0.01). The average values of HBVDNA are markly lower than before treatment in two groups at both 12,24 weeks (P < 0.01). At 12 weeks, the negative-turning rate of HBVDNA in the ICWM group is 79.17%, which shows significant difference in comparision with 40.00% in the TCM group (P < 0.01). The negative-turning rate of HBeAg in the ICWM group is 26.92%, which shows no significant difference in comparision with 32. 08% in the TCM group. At 24 weeks, the negative-turning rate of HBVDNA in the ICWM group is 85.71%, which shows significant difference in comparision with 50.00% in the TCM group (P < 0.01). The negative-turning rate of HBeAg in the ICWM group is 36.36%, which shows no significant difference in comparision with 28.57% in the TCM group. At 12 weeks,the total effective rate of the ICWM group is 96. 43%, which shows significant difference in comparision with 71.26% in the TCM group (P<0.01). At 24 weeks, the total effective rate of the ICWM group is 88. 00%, which shows significant difference in comparision with 67.61 % in the TCM group (P < 0.01). The average values of ALT and AST are markly improved than those of before treatment in two groups (P < 0.01). The average values of ALB is markly higher than before in TCM groups after 24 weeks treatment (P < 0.01).

CONCLUSIONFufang Huangqi granule integrated with lamivudine possesses a better effect for counteracting the hepatitis B virus and improving the liver functioin than only itself.
