AlM:To explore the clinical outcome of trabeculectomy with mitomycin C ( MMC) on glaucoma.
METHODS: A total of 57 patients (95 eyes) of primary glaucoma were randomly divided into two groups, 31 patients ( 54 eyes ) in trabeculectomy with MMC ( T+MMC ) group, which received trabeculectomy with 0. 2mg/mL MMC in surgical sites, and 26 patients ( 41 eyes ) in trabeculectomy ( T ) group. The anterior chamber, bleb, intraocular pressure ( lOP ) and complications were observed. The post-operative follow-up periods ranged between 4 and 6mo.
RESULTS:The mean lOP was 11. 24 ± 3. 73mmHg on 1d in group T+MMC. There was the significant difference compared with preoperative lOP ( P<0. 01 ), while no difference with the group T (P>0. 05). At final follow-up, the lOP was significantly different between group T+MMC and group T (16. 15±3. 62mmHg vs 18. 79±5. 27mmHg, P<0. 05). The rate of bleb formation was 94. 44% and 80. 48%in group T+MMC and T, respectively (P<0. 01). The postoperative complications were seldom, hyphema and corneal edema, and were cured finally.
CONCLUSlON:Trabeculectomy with MMC for glaucoma can effectively reduce postoperative scar formation of the filtration passage and lower the lOP to a target level with fewer complications.

Ginseng is a typical adaptogen which has resistance to various stresses. This effect is related to the hypothalamic-pituitary-adrenal (HPA) axis. As the main active ingredients, saponin has the similar structure to steroids. The regulation characteristics of ginseng saponin on the HPA axis are narrated from the aspects of total saponin and saponin monomers in this paper after the introduction of adaptation definition and HPA axis regulation mechanisms. Pharmacological effects of ginseng saponin and the regulation effect of HPA axis are summarized finally.

Objective:To investigate clinical features, risk factors and prognostic effects of paradoxical response(PR)in children with tuberculous meningitis(TBM)during anti-tuberculosis treatment.Methods:The clinical and follow-up data of TBM children admitted to the Department of Pediatrics, the Affiliated Hospital of Zunyi Medical University between January 2013 and December 2018 were retrospectively analyzed.The children were divided into the PR group and the non-PR group.Influencing factors of PR were selected by the univariate analysis, and independent risk factors were screened from these influencing factors by using the multivariate Logistic regression model.The effect of PR on long-term prognosis (≥9 months) of TBM was evaluated. Results:There were 31 cases(35.6%)with PR among the 87 TBM children enrolled, including 16 boys and 15 girls, with median age of 92(8-168)months.The median time for PR occurrence during the anti-tuberculosis treatment was 33(15-180)days.PR could present dete-rioration or recurrence of original symptoms, cerebrospinal fluid(CSF)deterioration and neuroimaging deterioration, accounting for 71.0%(22/31 cases), 80.6%(25/31 cases)and 51.6%(16/31 cases), respectively.Univariate analysis showed that stage Ⅱ, limb paralysis, cranial nerve palsy, positive tests of tuberculosis infection(T-SPOT), an increased lactate dehydrogenase(LDH)level in CSF, basilar meningeal enhancement, and tuberculosis infection outside the central nervous system were the influencing factors of the PR(all P<0.05). Multivariate analysis showed that limb paralysis, cranial nerve palsy, an increased CSF-LDH level, and positive T-SPOT were independent risk factors of PR(all P<0.05). PR was not associated with prognosis( P=0.165). Conclusions:PR occurs in 35.6% of children with TBM.Limb paralysis, cranial nerve palsy, an increased CSF-LDH level and positive T-SPOT are independent risk factors of PR.PR does not adversely affect the outcome.Identifying PR is extremely important for the prevention of some clinical misunderstandings.

ObjectiveTo investigate the intelligence characteristics and relativity with motor development of children with spastic diplegia.MethodsIntelligence and motor development of 46 children with spastic diplegia were tested by Wechsler Intelligence Scale and Motor Development Milestone (MDM), to find out difference of intelligence between the children with diplegia and the normal control group.ResultsIntelligence quotient (IQ) of children with spastic diplegia was lower significantly than the normal control, specially performance IQ (PIQ). PIQ was related with motor development. The more delayed motor development was, the more lower PIQ was. Subtest scores of animal egg, puzzle, block design and picture generalization were lower in spastic diplegic children with normal IQ than that of the normal control group, while vocabulary IQ (VIQ) was not different.ConclusionThe intelligence structure of children with spastic diplegia is imbalanced and PIQ of those children is significantly lower than the normal children, which is related to hands-eyes correspond, sight-motor correspond and speed, and space-sight ability.

Objective:To investigate the effect of metformin and arsenic trioxide on KG1a cells proliferation of acute myeloid leukemia and its possible mechanism.Methods:CCK-8 method was used to detect the killing effect of metformin,arsenic trioxide and combined application on KG1a cells.Annexin V-FITC/P1 Dual Stain Flow Cytometry was used to detect the effect of combined application on apoptosis of KG1 a cells.Western blot was used to detect the expression of intracellular apoptosis-,autophagy-related protein.Results:Metformin and arsenic trioxide alone or in combination could inhibit the proliferation of KG1 a cells and induce apoptosis of KG1 a cells,and the proliferation inhibition rate and apoptosis rate in the combined drug group were higher than those in the drug group alone(P＜0.05).The combination of drugs induced upregulation of Caspase 8 protein and P62 protein expression and was higher than that in the drug group alone(P＜0.05).Conclusion:Metformin can synergize with arsenic trioxide to kill KG1a cells,and its mechanism of action may be related to inducing apoptosis and enhancing autophagy.

ObjectiveTo study the state of oxidative injury induced by sodium arsenite(NaAsO2) in SV-40-immortalized normal uroepithelial (SV-HUC-1 ) cells.Methods SV-HUC-1 cells were exposed to different concentrations of NaAsO2[0(control),1,2,4,8,10 μmol/L] for 24 h,intracellular reactive oxygen species (ROS) was determined by flow cytometry,and the content ofintracellular nitrotyrosine(NT) and the 8-Hydroxydeoxyguanosine (8-OHdG) levels of cell culture medium were detected by enzyme linked immunosorbent assay (ELISA).Results After 24 h treatment,ROS levels(81.76 ± 4.91,95.23 ± 2.17,126.61 ± 17.95,126.74 ± 27.77,114.18 ± 9.65) of SV-HUC-1 cells in the 1,2,4,8,10 μmol/L NaAsO2 exposure groups were significantly higher than those of the control group (69.84 ± 1.28,P ＜ 0.05 or ＜ 0.01 ),ROS levels and exposure dose were positively correlated significantly(r =0.818,P＜ 0.01); the content of NT in the 10 μmol/L NaAsO2 exposure group[(919.66 ± 206.33) μg/L] was significantly higher than that in the control group[ (238.19 ± 38.28)μg/L,P ＜ 0.01 ],NT content and dye concentrations of arsenic also had dose-response relationship (r =0.617,P ＜ 0.01); after 24 h the cells were treated with arsenic,no significant difference of 8-OHdG content in the culture medium was observed(F =2.127,P ＞ 0.05 ).ConclusionNaAsO2 can cause SV-HUC-1 cell oxidative damage.

The human canstatin cDNA was amplified by RT-PCR and then directionally cloned into pU? expression vector. The recombinant pU?-Can vector was connected with the screening marker (bar box), to construct a eukaryotic expression vector called pU?-Can-Bar. This expression vector was introduced into the D.salina by glass beads method. The screening culture of transformants of D.salina was performed in solid media containing 5 ?g/ml PPT, and the analyses of transformants were carried out through PCR and Southern blot. PCR results revealed that specific 700 bp products were detected in the different transformants of D.salina but not in negative control. Southern blot analysis further demonstrated that human canstatin gene was integrated into the D.salina genome. Moreover, the results of genetic stability analyses of transformants demonstrated that canstatin gene was stably inherited in the D.salina transformants. The successful preparation of the D.salina transformants will provide the experimentation evidence for producing canstatin protein cosmically by using the D.salina bioreactor and give a better prophase work basis for clinic application of canstatin protein early.
