AIM:To explore the application effect of pranoprofen combined with tobramycin and dexamethasone ophthalmic suspension in cataract extraction after IOL implantation.METHODS:Retrospective analysis of the clinical data of cataract patients treated from May 2015 to June 2016 in our hospital.According to the treatment methods, patients were divided into tobramycin and dexamethasone ophthalmic suspension with pranoprofen group (combined treatment group) and pranoprofen treatment group.The difference of visual acuity, intraocular pressure, anterior chamber flash change, satisfaction rate and symptom score before and after treatment in two groups were observed.RESULTS:The vision of the two groups before treatment had no difference(P>0.05).At 1wk and 1mo after treatment, the visual acuity of the two groups all improved compared with before treatment, there was no significant difference between the two groups (P>0.05).Before treatment, the anterior chamber flare of the two groups had no difference(P>0.05).At 1wk and 1mo after treatment, the anterior chamber flare of combined treatment group was lower, the difference was statistically different (t=2.435, 1.864;P<0.05).The symptom score of the two groups before treatment had no difference(P>0.05).After treatment, the symptoms and signs of combined treatment group was significantly lower than that of pranoprofen group (t=2.586, 7.820;P<0.05).The satisfaction rate of the combined treatment group patients was 100%, significantly higher than pranoprofen group.CONCLUSION:Pranoprofen and tobradex in the treatment of cataract extraction and intraocular lens implantation has good application effect, can significantly improve the patient's symptoms and signs.

The relationship between the expression of resistin in polycystic ovary syndrome (PCOS) and insulin resistance was investigated. The plasma resistin concentrations in 35 patients with PCOS and 40 controls were measured by ELISA. Luteinizing hormone (LH), follicle-stimulating hormone (FSH), and fasting insulin (FIN) were tested by radioimmunoassay. Insulin resistance index (HOMA-IR) was calculated. Fasting plasma glucose (FPG) was determined by oxidase test. Western blot and reverse transcriptase PCR (RT-PCR) methods were used to detect the expression of resistin in adipose tissues. The levels of plasma resistin, LH, LH/FSH and FIN and HOMA-IR in patients with PCOS were significantly higher than those in control group (all P<0.05). Plasma resistin was correlated positively with FPG, FIN, HOMA-IR, LH and LH/FSH (r=0.56, 0.60, 0.65, 0.48, and 0.42 respectively). Resistin protein and mRNA expression levels in patients with PCOS were significantly higher than those in normal tissues (all P<0.01). It was concluded that resistin might be involved in the pathogenesis of insulin resistance of PCOS.

Objective To analyze the effect of bifrontal decompressive craniectomy on patients with refractory diffusing of brain swelling after severe traumatic brain injury.Methods The clinical data of 68 patients with refractory diffusing of brain swelling after severe traumatic brain injury were analyzed retrospectively.Thirty-five patients were performed with bifrontal decompressive craniectomy as observed group,continued intracranial pressure monitoring after surgery.Thirty-three patients were treated conservatively to reduce intracranial pressure as control group,continued intracranial pressure monitoring.The Glasgow outcome scale after discharge 6 months were assessed.The efficacy,the incidence of complications were observed in observed group.Results The admission intracranial pressure in observed group was significantly higher than that after surgery [(35.9 ±6.9) mmHg (1 mmHg =0.133 kPa) vs.(17.5 ±5.2) mmHg,P ＜0.05].The admission intracranial pressure in control group was (34.2 ± 8.6) mmHg,after admission 10.5 h was (32.0 ±4.8) mmHg (P ＜0.05),difference was no statistically significant (P＞ 0.05).The intracranial pressure after admission 10.5 h in control group was significantly higher than that in observed group after surgery (P ＜0.05).Two cases of subdural effusion,1 case of postoperative hydrocephalus in observed group.The better prognosis rate in observed group was significantly higher than that in control group [45.7％ (16/35) vs.18.2％ (6/33),P ＜ 0.05].Conclusions Bifrontal decompressive craniectomy is a suitable measure to decrease the intracranial pressure in the patients with refractory diffusing of brain swelling.If carried out early,it could provide better outcome for these patients.

ObjectiveTo evaluate the theoretical knowledge level of Chinese students majoring in stomatology based on the problem-based learning (PBL).MethodsThe Cochrane reviewer's handbook was followed by.Domestic published articles from 1989 -2010 were selected by computer and handwork.All these retrieved studies were controlled clinical trials related to oral theoretical education and were conducted by PBL and the traditional teaching methods.The quality of included studies was critically evaluated and the data were analyzed by the RevMan 5.0.1 software.ResultsA total of 138 articles were selected,but only 8 were included.Significant differences were found when the data were pooled(P ＜ 0.01,I2 =80％ ) and random effect model was used for meta-analysis.The results showed that comparing with the traditional teaching methods,PBL can improve the theoretical score of dental students [ MD 5.39,95％ CI(2.20,8.58)],and sensitivity analysis showed that the result was stable.ConclusionPBL can improve the theoretical score of Chinese students majoring in stomatology.However,as part of the studies are not high quality literature,the above conclusion needs to be verified by more large sample-sized,rigorously designed randomized controlled clinical trials.
