Objective Although the correlation between high risk human papilloma virus (hrHPV) infection and cervical cancer ( CC ) or cervical intraepithelial neoplasia ( CIN ) is well known , vaginal cancer ( VC ) or vaginal intraepithelial neoplasia ( VAIN) also caused by hrHPV has not received enough attention .This article aims to explore the clinical characteristics of VC or VAIN after operations of CC or CIN in order to provide evidence for the treatment of these diseases . Methods The clinical charac-teristics and treatment of 15 cases with VC or VAIN after operations of CC or CIN were reviewed from Jan 2010 to May 2013 in our hos-pital. Results The mean age was (53.6 ±10.82) years, ranged from 39 to 73 years.The duration from the first operation to devel-oped VAIN or VC was (25.07 ±18.31) months, ranged from 1 to 60 months.There are 4 cases developed VC, 4 cases VAINⅢand 2 cases VINⅡfrom 10 CC patients;and 3 cases developed VC , 2 cases VAINⅢfrom 5 CINⅢpatients.hrHPV test were positive in all 15 patients.Treatment in these series were performed including total vaginectomy in 8 patients (3 VC, 4 VAINⅢ and 1 VAINⅡpatients), pelvic lymphonectomy in 1;upper vaginectomy in 2 patients (1 VC, 1 VAINⅢ), radiation or chemo-radiation therapy in 3 (3 VC), interferon muscle injection combined with topical application of estrogen and acyclovir gel in 2 (1 VC, 1 VAINⅡ). Conclusion Careful follow-up after CC or CIN operations are very important because continued hrHPV infection may result VC and VAIN lesions.Vaginectomy may be the best therapy .Interferon muscle injection combined with topical application of estrogen and acyclovir gel are also alternatively therapy , especially for hard to operate patients . Radiation therapy seems to be not very adaptable for VAIN patients .

Hepatic fibrosis models were induced by CCl4 in rats. To explore vascular endothelial growth factor (VEGF), transforming growth factor-beta1 (TGFβ1) mRNA expression and bcl-2, Bax protein expression levels of intervention and explore the mechanism of the Aralia chinesis anti-hepatic fibrosis. Sixty male Sprague-Dawlley (SD) rats were randomly divided into six groups: nomal group, model group, high-dose (10 mL x kg(-1)), medium-dose (7.5 mL x kg(-1)), low-dose (5.0 mL x kg(-1)) of A. chinesis treated group and colchicine treated group. The change of liver histopathology was observed by HE and Masson staining. The mRNA of VEGF, TGF-β1 were detected by RT-PCR. The protein of Bcl-2 and Bax were detected by Western blot. In the model group liver cell obvious degeneration, necrosis, a large number of collagen fibers of the cable hyperplasia, part visible pseudolobule formation. A. chinesis large, medium, low-dose group and colchicine group liver cell degeneration and necrosis reduced A. chinesis small, medium, and high-dose group was gradually reduced trend and A. chinesis large, middle dose group degree of reduction is particularly significant. Compared with model group, A. chinesis of large, medium and small dose group and colchicine group VEGF mRNA expression, A. chinesis of large, medium-dose group TGF-β1 mRNA expression reduce (P < 0.05); compared with colchicine group, A. chinesis of large, middle dose group of VEGF mRNA expression decreased (P < 0.05); A. chinesis of large, middle dose group of TGF-β1 mRNA expression decreased (P < 0.01), and compared with colchicine group, large dose group of of TGF-β1 mRNA expression decreased (P < 0.05). Compared with model group, A. chinesis of large, medium and small dose group and colchicine group Bcl-2 protein expression reduce (all is P < 0.05). But A. chinesis of large, medium and small dose group and colchicine group of Bax protein expression were increased (P < 0.05). A. chinesis regulation of VEGF, TGF-β1 may prevent the activation of hepatic stellate cells, liver tissue by up regulating the anti-apoptotic protein Bax and down pro-apoptotic protein Bcl-2 expression, thereby to improve the degree of liver fibrosis.

OBJECTIVE: To analyze and discuss four methods of calculating likelihood ratio of DNA mixture. METHODS: In the case with CNAS-T0757 proficiency testing in 2013, the likelihood ratios were calculated and compared among four methods, including unrestricted combinatorial method, Clayton's method, p2 principle method, and recommendations from ISFG. RESULTS: The likelihood ratios were maximum by Clayton's method and recommendations from ISFO, followed by result of the unrestricted combinational method. The minimum likelihood ratio was obtained by p2 principle. CONCLUSION The unrestricted combinational method could give fUrthest consideration to both information preservation and appraiser protection.

Abstract: Objective　To analyze the laboratory indexes of patients infected with malaria patients and COVID-19, so as to provide reliable evidence for the diagnosis of mixed infection of both. Methods　The routine clinical laboratory items such as routine blood, biochemistry and lymphocyte subsets were tested in three cases of COVID-19 complicated with falciparum malaria who admitted to Guangzhou Eighth People's Hospital Affiliated to Guangzhou Medical University from July to December 2020 were tested. Laboratory data were stage-wise analyzed in conjunction with changes in the course of disease. Results　Three patients confirmed COVID-19 infection recruited all had malaria infection history. Fever, headache, and other symptoms emerged on the 4rd to 11th day after admission. Malaria parasite was detected by malaria parasite antigen testing and blood smear testing, and all three patients had re-ignition of malaria after being confirmed COVID-19 infection. In the early stage of malaria relapse, lymphocytes decreased, CRP and SAA increased, and gradually returned to normal level after antimalarial treatment. Interestingly, we only found one patient at the initial stage of malaria detection showed PLT decreased, no other unnormal changes in other routine blood results (WBC, ESO) and liver function results (ALT, AST, GGT, TBIL, DBIL, CG) were found from the beginning to end course of the disease. Conclusion　COVID-19 infection may promote the resurgence of malaria, so the relapse of malaria should be monitored especially for the patient with malaria infection history who begin to develop fever and other symptoms a few days after the diagnosis of COVID-19. The inflammatory indicators would be worth able as an auxiliary judgment basis for the effective treatment of the two combined infection.

Objective:To prepare mesalazineβ-cyclodextrin inclusion compound and observe its properties. Methods:The struc-ture was characterized by UV, IR and DSC. The inclusion process of mesalazine andβ-cyclodextrin was simulated using molecular doc-king technique. The solubility and dissolution of inclusion compound were determined. Results:UV, IR and DSC were used to deter-mine the formation of inclusion complex. The inclusion ratio was 1: 1 and the phase solubility diagram was AL type. The solubility of inclusion compound in deionized water (25 ℃, pH 7. 0) was 7. 8 mg·ml-1 . The preparation of mesalazine β-cyclodextrin inclusion compound could significantly increase the dissolution rate and solubility of mesalazine. Conclusion:The prepared mesalazineβ-cyclo-dextrin inclusion compound can obviously improve the poor water solubility and dissolution of mesalazine.

The development, application and revision of the clinical practice guideline (CPG) in traditional Chinese medicine (TCM) are a whole thing. However, the development and revision of TCM CPGs have been influenced due to lack of TCM CPGs reporting and feedback channel. Therefore, during the TCM standardization network establish-ment, we studied the application model of TCM CPGs with spontaneous reporting network, in order to provide the ba-sis for further TCM CPGs development and revision.

Objective To explore the effects of Levoeitirize dihydrochloride on interleukin-13(IL-13)and interleukin-18(IL-18)in the serum of the patients with cough variant asthma(CVA).Methods 70 cases with CVA were randomly devided into control group of 35 cases and treatment group of 35 cases.Control group was given Chlort rimeton and the treatment group was given Levocitirize dihydroehloride.The levels of IL-13 and IL-18 in the serum were measured before and after treatment.Results After treatment,the concentrations of IL-13 and IL-18 in patients in the treatment group were(46.7±17.3)ng/L and(145.2±27.1)ng/L，and those in the control group were(98.5±30.7)ng/L and(179.6±30.5)ne/L，which were significantly improved.Conclusion The treatmem of Levoeitirize dihydrochloride could improve the CVA through improving the production of IL-13 and IL-18.

Objective To observe the consistency of T-cell receptor (TCR) genes mutation in lymphocytes in rats after irradiation in vivo and in vitro.Methods A total of 48 female rats were randomly divided into 6 equal groups.Peripheral blood samples from them were collected to separate the lymphocytes and then irradiated to X-ray irradiation with the dose rate of 200 cGy/min at the doses of 0,0.5,0.75,1.0,2.0,and 3.0 Gy,respectively.Then all the lymphocyte samples were cultured for 7 days.Flow cytometry with direct immunofluorescence was used to detect the TCR gene mutation.The levels of TCR gene mutant frequency (TCRMF) of different groups were calculated.Results The TCRMF levels of different groups after irradiation in vivo and in vitro all displayed a dose-dependent manner and there were no significant differences in the TCRMF between different dose irradiation groups(t = -1.1-0.3 ,P ＞0.05).Conclusions A consistency of TCRMF after irradiation in vivo and in vitro is proven.The results of TCRMF of peripheral blood lymphocytes irradiated in vitro by flow cytometry can precisely reflect the TCR genes mutation after whole-body irradiation.
