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.

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.

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.

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.

OBJECTIVETo investigate the inhibitory effect of RNA interference on chronic myeloid leukemia (CML) bcr/abl oncogene expression.

METHODSThe small interference RNAs (siRNAs) were synthesized in vitro. K562 cells stably expressing bcr/abl gene were transfected with the siRNA by electroporation, both the non-transfected cells and non-specific siRNAs transfected cells were taken as controls. The enhanced green fluorescent protein (EGFP) plasmid was used as positive control and the transfection efficiency was detected by flow cytometry. Inhibitory effect of siRNAs was demonstrated by real-time quantitative RT-PCR and Western blots. Cell proliferation was measured by MTT assay and apoptosis by Annexin V-FITC assay.

RESULTSThe transfection efficiency was about 70%. The synthesized siRNAs inhibited CML bcr/abl oncogene expression at both mRNA and protein levels. siRNAs could inhibit K562 cell proliferation to 47% and 56% at 24 h and 48 h after transfection, respectively, and induce cell apoptosis from 1.00% in control group to 15.05% and 19.4% at 24 h and 48 h respectively.

CONCLUSIONAt the cell level, inhibition of CML bcr/abl oncogene expression by chemically synthesized siRNAs provides the new method for anti-leukemia study.

Osteogenesis imperfecta is a group of inherited connective-tissue disorders in which synthesis or structure of type I collagen is defective and causes osseous fragility. Type IV osteogenesis imperfecta is dominant inheritance. Here, we report a case of type IV osteogenesis imperfecta family and their female member's pregnancy. Abnormal sonographic findings (marked bowing and shortening of long bones) and family history made the diagnosis of fetus with osteogenesis imperfecta. The parents decided to give up rescuing the infant and a caesarean section at 27 weeks of gestation was implemented. In conclusion, it is possible to make a prenatal diagnosis of osteogenesis imperfecta by ultrasound. For the pregnant women with osteogenesis imperfecta, management decision should be made on an individual basis.

OBJECTIVETo investigate whether there is an association between DRD2/ANKK1 Taq IA polymorphism and early infant temperament.

METHODSDRD2/ANKK1 Taq IA polymorphism (rs1800497) was determined using polymerase chain reaction-ligase detection reaction (PCR-LDR) techniques in 149 Chinese Han infants from Changsha City. Their mothers were asked to complete the Early Infant Temperament Questionnaires (EITQ) when the infants were 1 to 4 months old (mean: 2.75 months). There were three genotypes found in these infants: C/C, T/T and C/T. The subjects were subdivided into T-carrier (CT, TT) and non-T-carrier (CC) groups for statistical analysis.

RESULTSThere were no differences in the temperament style distribution between the T-carrier and non-T carrier groups. There were also no statistically significant differences between the two groups in the score of the nine temperament dimensions.

CONCLUSIONSDRD2/ANKK1 Taq IA polymorphism is not associated with early infant temperament.
