Mycotic vaginitis is a common and frequently-occurring gynaecopathia and easy to attack repeatedly, so painful to patients. In this study, the authors observed the clinical efficacy of Sophora gel combined with Fluconazole capsules in treating mycotic vaginitis, in order to seek an effective method for treating mycotic vaginitis. Totally 85 patients with mycotic vaginitis treated in our hospital between December 2012 and July 2014 were randomly divided into the treatment group (43 patients) and the control group (42 patients). The treatment group was given vaginally Sophora gel (one piece every night for 14 days) and orally Fluconazole capsules (150 mg, once every three days, four times in total); The control group was only administered with Fluconazole capsules. The total efficacy, cure rate, recurrence rate and clinical symptom improvements of the two groups were observed. The results show that the total efficacy, the cure rate and the recurrence rate of the treatment group vs. the control group were respectively 97.7%, 90.7% and 2.6% vs. 83.3%, 71.4% and 20.0%, with statistical significance in their differences (P < 0.05). The treatment group showed reduced leucorrhea, pruritus vulvae disappearance and earlier mucosal hyperemia disappearance than the control group, with statistical significance in their differences (P < 0.05). In conclusion Sophora gel combined with Fluconazole capsules can improve antifungal activity of drugs, relieve clinical symptoms, shorten the course of disease, enhance the cure rate and reduce the recurrence rate; So this therapy can be widely applied in clinic.

Objective To examine whether neonate′s cord blood T-lymphocytes is related to infant temperament.Methods Twenty-five healthy babies were randomly chosen in Changsha from Jul.2005 to Aug.2005 and their cord blood was drown when they were born. CD4+ and CD8+ counts, CD4+%, CD8+%, CD4+/ CD8+ratios were obtained using flow cytometry analysis. Infant temperament were measured after 1-4 months( mean age 2.52 months) with parent response to carey revised infant temperament questionnaire(EITQ/RITQ) administered.Results The percentage of CD4+ T-cell subsets to total lymphocytes correlated negatively with persistence scores (r=-0.43 P=0.033). However, CD8+%, CD8+ and CD4+ counts, CD4+/ CD8+ ratios were not correlated with temperament traits.Conclusions The lower CD4 %, the better infants' persistence.

AIM: To observe the changes of anterior chamber angle after posterior chamber intraocular lens(ICL)V4c implantation for high myopia.

METHODS: Prospective study. ICL V4c implantation was performed on 150 cases(300 eyes)with high myopia, and the changes of visual acuity, intraocular pressure,vault and anterior chamber angle were recorded before and 1d, 1mo, 3mo, 6mo and 1a after operation. Repeated measurement analysis of variance and LSD-t test were used to analyze the data.

RESULTS: After 1d, 1mo, 3mo, 6mo, 1a operation, the recovery of UCVA was significantly higher than that before operation(F=98.2, P<0.01); there were statistically significant differences in AOD500, AOD750, TISA500, TISA750 and SSA of nasal side before and after operation(F=108.256, 112.342, 164.856, 316.549, 115.338, P<0.01); there were statistically significant differences in AOD500, AOD750, TISA500, TISA750 and SSA of temporal side before and after operation(F=102.68, 548.47, 93.37, 316.549, 117.698, all P<0.01); the parameters of each angle decreased gradually in the 1d, 1mo and 3mo after operation on both sides, and there was statistical difference in the two comparisons(all P<0.05), but there was no statistical significance in the parameters of each angle in the 3mo, 6mo and 1a after operation(all P>0.05).

CONCLUSION: After ICL V4c implantation, the anterior chamber angle parameters in the horizontal direction of 1d, 1mo, 3mo, 6mo and 1a were smaller than those before operation, and tended to be stable after 3mo.

Abstract: Objective To explore and analyze the diagnostic value of multicolor melting curve analysis (MMCA) for the resistance of five anti-tuberculosis drugs, so as to clarify the clinical value of MMCA in detecting drug resistance of Mycobacterium tuberculosis. Methods From April 2021 to May 2022, 200 patients with positive Mycobacterium tuberculosis admitted to the Fourth People's Hospital of Qinghai Province were selected as research objects, and sputum specimens were taken from the patients. Traditional Mycobacterium tuberculosis drug sensitivity test (modified Löwenstein-Jensen medium method) and MMCA analysis were respectively given to detect the resistance of five anti-tuberculosis drugs, including isoniazid, ethambutol, streptomycin, rifampicin and isoniazid, respectively. Those samples with inconsistent results between the two diagnosis methods were subjected to gene sequencing verification, and the diagnosis efficiency of MMCA for the five anti-tuberculosis drugs was compared. Results Using Mycobacterium tuberculosis drug sensitivity as the gold standard for drug resistance diagnosis, the sensitivity of MMCA for detecting drug resistance of rifampicin, ethambutol, streptomycin, isoniazid and levofloxacin were 95.83% (46/48), 93.75% (15/16), 100.00% (15/15), 100.00% (20/20) and 70.00% (7/10), respectively, with statistical differences between groups (P<0.05). There were no statistically significant differences in the specificity, positive predictive value, negative predictive value and accuracy of MMCA for the five anti-tuberculosis drugs (P>0.05). For the 8 samples with inconsistent results between MMCA and modified Löwenstein-Jensen medium method, gene sequencing was performed and compared with the results of gene sequencing. After comparison with gene sequencing results, it was found that the coincidence rate of MMCA and gene sequencing results was 75.00% (6/8). Conclusions In the detection of drug-resistant mutations in TB patients, multi-color probe fusion curve analysis has high diagnostic efficacy for first-line anti-tuberculosis drugs, but is not sensitive to second-line anti-tuberculosis drug levofloxacin. Therefore, for the detection of first-line anti-tuberculosis drugs, MMCA has a good clinical application prospect.

Background and Objective: The expression of transcription factor Elf-1 and inhibitor of apoptosis survivin in non-small cell lung cancer(NSCLC)is correlated with the angiogenic factor vascular endothelial growth factor(VEGF),and are both factors affecting the cell cycle.This study investigated the expression of Elf-1,survivin,and intratumoral microvessel density(iMVD)assessed by monoclonal antibody CD105 in NSCLC,and explored their correlations with clinicopathologic features and angiogenesis of NSCLC.Methods: PowerVisionTM-9000 immunohistochemistry was used to evaluate the expression of Elf-1,survivin,and CD105 in tissue microarrays containing60 specimens of NSCLC and 9 specimens of normal tissue.Western blot analysis was used to evaluate the protein levels of Elf-1 and survivin in 17specimens of NSCLC and 5 specimens of normal tissue.Results: Elf-1 and survivin were detected in 1 of the 9 normal tissues.The positive rates of Elf-1and survivin in NSCLC were 70.0% and 65.0%,respectively.The expression levels of both Elf-1 and survivin were significantly related to tumor differentiation,lymphatic metastasis,clinical stage,and postoperative survival time(P<0.05).Overexpression of both were related to poor prognosis: the survival rates were significantly lower in patients with positive expression than in those with negative expression(P<0.01).Elf-1 expression was positively correlated with survivin expression(r=0.769,P<0.01.Elf-1 and survivin expressions were positively correlated with iMVD(r=0.446,P<0.01 ; r=0.435,P<0.01).Conclusions: The expression of Elf-1 and survivin in NSCLC is related to differentiation,lymphatic metastasis,clinical stage,and prognosis,and both are positively correlated with iMVD.Detection their combined expression can help to predict the malignant behavior of NSCLC.Blocking the activity of Elf-1 and survivin may be a new way to inhibit angiogenesis in NSCLC.

MISA (MicroSAtelite) software was employed to screen SSRs in 68 787 contigs of Swertia mussotii transcriptome sequences. 5 610 SSRs were distributed in 5 099 contigs which accounted for 7.41% of 68 787 contigs. There are 220 kinds of SSR motifs existing in S. mussotii transcriptome. On average, SSRs occurred every 12.60 kb in length. In the SSRs, the tri-nucleotide repeat motif was the most abundant (45.99%), followed by the di-nucleotide (41.62%). AT/TA and AAT/TTA were the main types of motif in di-, tri-nucleotide repeats. The repeat numbers of SSRs which from S. mussotii transcriptome SSRs were mainly from 5 to 10 and motif length of them mostly ranged from 12 bp to 30 bp. A total of 30 651 contigs were annotated, and only 1 447 SSRs were occurred in protein-coding regions. In the six repeat motifs, tri-nucleotide repeats were the most abundant in coding regions (928). There are abundant SSRs in S. mussotii transcriptome with high frequency and various types, indicating their usefulness in theory. This research may lay the foundation for designing the targeted SSR primers and developing SSR molecular markers by mining the information of SSRs loci in S. mussotii transcriptome sequences data.

OBJECTIVETumor necrosis factor related apoptosis inducing ligand (TRAIL) induces cell death in a variety of tumors but not in normal cells. TRAILdouble ended arrow-resistance of most neuroblastoma (NB) cell lines is related to the loss of caspase-8 expression and the expression and distribution of membrane TRAIL-receptors. This study investigated the role of caspase-8 and DR5 in TRAIL-induced apoptosis of NB cell line SKNDZ.

METHODSThe expression of caspase-8 mRNA was detected by RT-PCR. The expression of DR5 protein was detected by Western Blot analysis. The effects of TRAIL, IFNgamma +TRAIL, chemotherapeutic agent (adriamycin or etoposide) + TRAIL, and chemotherapeutic agent +TRAIL+ IFNgamma on the growth and apoptosis of SKNDZ cells were detected by MTT assay and flow cytometry.

RESULTScaspase-8 was not expressed in SKNDZ cells but IFNgamma treatment resulted in an increase of caspase-8 expression. Expression of DR5 protein was not detected in SKNDZ cells but an increased DR5 protein expression was found after treatment with adriamycin or etoposide. The SKNDZ cells expressing caspase-8 were not sensitive to TRAIL but those SKNDZ cells expressing both caspase-8 and DR5 were sensitive. The early apoptosis rates of the adriamycin /etoposide + IFNgamma+TRAIL groups [(17.9 +/- 3.6)%, (14.8 +/- 3.3)%] were higher than that of the IFNgamma+TRAIL group [(3.9 +/- 1.2)% ](F=26.233, P < 0.01).

CONCLUSIONSSKNDZ cells expressing both caspase-8 and DR5 restored the TRAIL sensitivity. Caspase-8 and DR5 play a key role in TRAIL-induced apoptosis of NB cells.

Spiramycin (SP) belongs to the 16-member macrolide antibiotics. It contains three components,namely SP I, SP II and SP III, which differ structurally in the acylation moieties on the C3 of the lactone. The SP I component contains a hydroxyl group at C3. SP II, and SP III are formed by further acetylation or propionylation of the C3 of SP I, by the same 3-O-acyltransferase (3-O-AT) . The study focused on simplifying spiramycin components. Theoretically, disruption/deletion of the 3-O-AT gene will reduce/stop the acylation of SP I to SP II and SP III. In this study, degenerated primers were designed according to the conserved regions of 3-O-acyltransferase, MdmB and AcyA in the medicamycin and carbomycin producers of S. mycarofaciens and S. thermotolerans, respectively, and an 878bp DNA fragment was amplified from the spiramycin-producer of S. spiramyceticus F21. Blast analysis of the 878bp DNA fragment suggested that it encoded the 3-O-acyltransferase (3-0-AT, sspA) gene for spiramycin biosynthesis. The flanking regions of this 878bp DNA fragment were then amplified by single-oligonucleotide-nested PCR, and a total of 4.3 kb DNA was obtained (3457nt among the 4.3kb fragment was sequenced, and deposited in GenBank DQ642742),covering the whole putative 3-O-acyltransferase gene, sspA. The sspA was then deleted from the S. spiramyceticus F21 genome by double cross-over homologous recombination, mediated by temperature-sensitive plasmid pKC1139. A comparison was done of the components of spiramycins produced by the sspA-deleted mutant strain with that of the parent strain by HPLC analysis, which showed that sspA-deleted mutant produced SP I (72%), SP II (18%), and SP III (9.6%), whereas parent strain produced SP I (7.8%), SP II (67%), and SP III (25%), respectively, demonstrating the role of ssp A in the acylation of SP I into SP II and SP III. The ssp A-deleted mutant strain obtained in this study may be used for the production of SP I, or may serve as a good starter for the construction of spiramycin derivatives.

OBJECTIVETo study the effect of gamma-interferon (IFNgamma), tumor necrosis factor related apoptosis inducing ligand (TRAIL), and cisplatin or etoposide induced apoptosis in human neuroblastoma cell line SH-SY5Y and its possible molecular mechanisms.

METHODSThe expressions of Caspase 8 mRNA and protein were detected with RT-PCR and Western blot analysis. The effects of IFN-gamma, TRAIL, IFNgamma + TRAIL, IFN-gamma + Caspase 8 inhibitor + TRAIL, IFNgamma + cisplatin + TRAIL, and IFNgamma + etoposide + TRAIL on the growth and apoptosis of SH-SY5Y cells were detected with the methods of MTT and flow cytometry. The relative Caspase 8 activity was measured with colorimetric assay.

RESULTSCaspase 8 was undetectable in SH-SY5Y cells but an increased expression of Caspase 8 mRNA and protein was found after treatment with IFNgamma. SH-SY5Y cells themselves were not sensitive to TRAIL, but those expressing Caspase 8 after treatment with IFNgamma were. The killing effect of TRAIL on SH-SY5Y cells expressing Caspase 8 was depressed by Caspase 8 inhibitor. Cisplatin and etoposide could enhance the sensitivity of TRAIL on SH-SY5Y cells. The relative Caspase 8 activity of SH-SY5Y cells in IFN-gamma + TRAIL group was significantly higher than those of control group, IFN-gamma group, TRAIL group, and inhibitor group (P < 0.01). There was no significant difference among IFN-gamma + TRAIL group, IFNgamma + cisplatin + TRAIL group, and IFNgamma + etoposide + TRAIL group.

CONCLUSIONSIFNgamma could sensitize SH-SY5Y cells to TRAIL-induced apoptosis and this may be realized by the up-regulation of Caspase 8. Cisplatin and etoposide could enhance the killing effect of TRAIL on SH-SY5Y cells.
