Abstract: AIDS combined with Pneumocystis jirovecii pneumonia (PJP) and disseminated infections of Talaromyces marneffei and Cryptococcus neoformans are rare. This paper summarizes and analyzes the diagnosis and treatment of an AIDS patient with multiple fungal infections for reference. A 79-year-old male patient was admitted to the hospital with "stool habit change for more than 20 days". The white blood cell count was 4.57×109/L, the percentage of neutrophils was 81.8%, the absolute count of CD4+ lymphocytes was 6/μL, and the CD4/CD8 ratio was 0.17. HIV antibody positive was confirmed by CDC. The cerebrospinal fluid and alveolar lavage fluid were positive for Cryptococcus neoformans capsular antigen, and Pneumocystis jirovecii was found by the bronchoalveolar lavage fluid stained with hexamine silver. The cerebrospinal fluid culture was positive for Cryptococcus neoformans, and the blood culture was positive for Cryptococcus neoformans and Talaromyces marneffei. CT showed that bronchovascular bundles in both lungs were more thick, patchy and cable-like high-density shadows were seen in both lungs, and the edges were blurred. Nodular and cable-like high-density shadows were seen in the posterior apical segment of the left upper lobe, with clear margins. Infection of both lungs was considered, and secondary pulmonary tuberculosis occurred in the left upper lobe. After admission, the patient was treated with various anti-bacterial and fungal drugs due to recurrent fever, but the effect was not effective. The fever symptoms of the patient could not be significantly improved, and his condition continued to worsen, and he eventually died. The patient with AIDS complicated with bacterial and fungal infection, especially PJP infection in serious condifiton and has a poor prognosis for rapid development, so clinical attention should be paid to. 

OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.

Objective To investigate plasma glutathione S-transferase(GSTs) activity and GSTP1 gene Ile105Val polymorphism in Bijie City, Guizhou Province, a coal-burning fluorosis endemic area. Methods One hundred and sixty villagers from Yachi Twon using non-improved cooking stoves were selected as the non-intervened group in Bijie City, Guizhou Province where coal-burning fluorosis was prevailing; 153 villagers as the intervented group were chosen from Changchun Twon, where cooking stoves were improved; 151 villagers were served as the control group from Baiyunshan Twon, Changshun County without endemic fluorosis. The activity of GSTs was tested by colorimetric analysis with spectrophotometer. The genotype of the GSTP1 gene Ile105Val polymorphism, presenting as either homozygous wild-type (AA), or heterozygous mutation type (AG), or homozygous mutation type (GG), was detected through the PCR-RFLP procedure. Results The activity of GSTs in plasma of non-intervened group [(12.44±4.97) kU/L]was significantly lower than that of intervened group (P < 0.05), and that of intervened group[(20.78±6.20)kU/L]was significantly lower than that of control group[(24.30±6.27)kU/L, P< 0.05]. The difference of the enzyme activity of three groups were statistically significant (F = 51.71, P < 0.05), but this enzyme activity did not vary significantly in each sex of each grnup(P > 0.05). Compared intervened group [AA:67.3%(103/153), AG:29.4%(45/153),GG:3.3%(5/153)]and non-intervened group[AA:66.9%(107/160), AG:30%(48/160), GG:3.1%(5/160)]with control group[AA:74.8%(113/151), AG:25.2%(38/151), GG:0 (0/151)], the Ile105Val polymorphism site of GSTP1 gene had significant difference(χ2= 6.04,6.07, both P< 0.05), but not significant between intervened and non-intervened groups(χ2 = 0.02, P>0.05). Conclusions Fluorosis can decrease the activity of GSTs and introduce the GSTP1 gene Ile105Val polymorphism, intervention with the fluorine intake will improve the effect of fluoride on the body.

To obtain the tervalent fusion toxin gene (named FT),three toxin gene fragments from three species of Vibrio parahaemolyticus,Vibrio vulnificus and Vibrio mimicus were connected with the flexible linker (GGGGS) using overla Pextension PCR. The three toxin gene fragments respectively encode the mature proteins of the thermostable direct hemolysin (TDH) of V. parahaemolyticus,the cytotoxin (VVC) of V. vulnificus and the heat-labile hemolysin (VMH) of V. mimicus. The identity of FT nucleic acid sequence was 99.6% with the corresponding toxin gene fragments. The open reading frame of FT was 3225 bp,encoding 1074 amino acid residues with the predicted molecular weight (MW) of 120.4 kDa. Then,FT was subcloned into the expression vector pET-22b(+). The construction of recombinant expression vector pET-22b-FT was followed by transforming into E. coli BL21(DE3) for expression. The SDS-PAGE electrophoresis results indicated that the MW of the fusion toxin protein was matched to the predicted MW. After induction by 1 mmol/L IPTG at 37℃,the fusion toxin protein was effectively expressed in E. coli BL21(DE3) with the amount of 11.49% through thin layer chromatography scanning (TLCS) analysis. Cavia cobaya was immunized using the purified cytorrhyctes to produce the anti-serum. Through the determination of the optimum working conditions,the sensitivity test,the specificity test,repeatability test and sample simulation test,the indirect ELISA method was established,which is a broad-spectrum,rapid and specific to detect various of food-poisoning Vibrio simultaneously.

Objective To study the interactions between the highly pathogenic avian influenza H5N1 nucleoprotein (H5N1 NP) and NF-κB-inducing kinase (NIK),and to reveal the effect of H5N1 NP on NIK-induced NF-κB transcriptional activity.Methods The gene encoding NIK protein was amplified by RT-PCR from total RNA of HeLa cell line.Eukaryotic expression plasmid pCMV-Myc-NIK and prokaryotic expression plasmid pGEX-4T-1-NP (GST-NP) were constructed by cloning from HeLa cell cDNA and pcDNA3-Flag-NP vector,respectively.Co-immunoprecipitation (co-IP) and GST pull-down were used to test the interactions between H5N1 NP and NIK.Dual-luciferase reporter gene analysis system was used to test the effect of H5N1 NP on NIK-induced NF-κB transcriptional activity.Results Co-IP and GST pull-down showed that pCMV-Myc-NIK and pGEX-4T-1-NP (GST-NP) could express Myc tagged NIK protein and GST tagged NP protein in HEK293T cells and E.coli,respectively,and that H5N1 NP was associated with NIK in vivo and in vitro.Dual-luciferase reporter gene analysis suggested that H5N1 could inhibit NIK-induced NF-κB transcriptional activity.Conclusion H5N1 NP interacts with NIK and inhibits NIK-induced NF-κB transcriptional activity.This finding can facilitate further study of H5N1.
