AIM: To analyze the clinical value of femtosecond laser in vitrectomy combined with phacoemulsification and intraocular lens (IOL) implantation.
METHODS: We selected 100 patients ( 102 eyes ) undergoing vitrectomy combined with phacoemulsification and IOL implantation in our hospital from October 31 2013 to October 31 2015. They were divided into routine operation group, 50 cases (52 eyes), and femtosecond laser group, 50 cases (50 eyes). The parameters were compared between the two groups, including total operation time, postoperative complications ( elevated intraocular pressure, uveitis, vitreous hemorrhage, and retinal detachment ), postoperative intraocular pressure and postoperative half of the visual acuity ( near visual acuity, visual acuity, uncorrected visual acuity, corrected visual acuity).
RESULTS: The difference on total operation time of the two groups was statistically significant ( P < 0. 05). The differences between the two groups on postoperative intraocular pressure, uveitis, vitreous hemorrhage, retinal detachment were not statistically significant ( P >0. 05). There were no significant differences on internal pressure, near visual acuity, far visual acuity, uncorrected visual acuity, corrected visual acuity at 6mo after surgery (P>0. 05).
CONCLUSION: Femtosecond laser in vitrectomy combined with phacoemulsification and IOL implantation has a high safety and efficacy with the advantages as accurate, efficient.

AlM:To evaluate the early diagnosis of sub-clinic stage of diabetic retinopathy.
METHODS: This was cross sectional study, multifocal retina electroretinogram ( mf-ERG ) , contrast sensitivity ( CS) and central retinal artery color Doppler examination were recorded from 30 cases ( 30 eyes ) matched control subjects, 35 cases (35 eyes) with type 2 diabetes mellitus (DM) without diabetic retinopathy ( NDR) and 38 cases ( 38 eyes ) with non-prolifera tive diabetic retinopathy ( NPDR) . One-way ANOVA and SNK-q test were used for data analysis.
RESULTS: P1 response density of NDR patients were found decrease, N1 implicit time were delayed. Which were related with the degree of retinopathy (P<0. 05);CS of NDR patients were found significant in middle and high frequency ( P < 0. 05 ), NPDR patients were found significant in full frequency ( P<0. 05 ); Central retinal artery (CRA) blood flow in the control groups and NDR groups were not found statistically significant (P>0. 05), The differences between normal group, NDR group and NPDR group were found statistically significant (P<0. 05).
CONCLUSlON: mf-ERG and CS are sensitive indexes for early evaluation of visual function in patients with diabetes mellitus, with development of the disease, CRA blood flow also appears to decline.

To meet the need of cultivating the high-quality medical personnel,we have ad-justed and reformed the content of the "Clerkship" teaching in obstetrics and gynecology and conducted the survey and research among teaching philosophy,training mode and management mechanism,and have obtained more satisfactory teaching result.

Objective To find out the status of prevention and control of iodine deficiency disorders and evaluate the iodine nutritional status of Jinan residents,to explore appropriate iodine level in drinking water,and to provide a scientific basis for adjustment of intervention strategies.MethodsAccording to the Monitoring Program of the National Iodine Deficiency Disorders (Trial),qualified iodized salt consumption rate,drinking water iodine content and urinary iodine levels of women of childbearing age were determined in iodine deficiency areas from 2003 to 2010.Salt iodine was detected by direct titrimetry,urinary iodine by As-Ce catalytic spectrophotometric assay and iodine in drinking water by cerous sulfate catalytic spectrophotometric method.Results Intake rate of qualified iodized salt was up to 90％ and above from 2003 to 2010,median water iodine was 13.65 μg/L in the 10 counties(cities,districts),of which less than 100 μg/L accounted for 79.82％(4560/5713 ) and ＞ 150 μg/L accounted for 12.73％(727/5713).With the increase of water iodine(0 ～ ＜ 10,10 ～ ＜ 50,50 ～ ＜ 100,100 ～ ＜ 150,150 ～ ＜ 300 and ≥300 μg/L),urinary iodine levels of women of childbearing age increased successively(median 156.56,175.81,267.04,349.00,524.22,583.20 μg/L,respectively,x2 =121.20,P ＜ 0.05),while the ratio of urinary iodine ＜ 100 μg/L was significantly lower.The ratio of urinary iodine between 100 and 300 μg/L was decreased gradually,but the ratio of great than 300 μg/L was gradually increased.ConclusionsIodine deficiency areas in Jinan have reached the standard of elimination of iodine deficiency disorders.We should insist to carry out our measures to suit local conditions,classified guidances and scientific principals of iodine supplementation.

Study the infect of child anorexia granule on serum ghrelin and leptin of anorexia children and its clinical efficacy. Selected 81 cases of anorexia children aged 1-6 years old into treatment group (42 cases) and control group (39 cases), in addition, 30 case healthy children as healthy control group. The control group children were treated with domperidone suspension 0.3 mg x kg(-1) x d(-1), tid, orally 30 minutes before meals. Treatment group were treated with child anorexia granule, 1-3 years 1 package, bid; 4-6 years 1 package, tid; po, 4 weeks as a course of treatment. Study the change of serum ghrelin and leptin before and after therapy. The study demonstrates that before treatment, the serum ghrelin level of disease group was lower than healthy group (P < 0.01), and the serum leptin level was higher than healthy group (P < 0.01). After treatment, the serum ghrelin level both increase, and the serum leptin decline. And the change of treatment group was significantly different with control group (P < 0.01). And the clinical effective rate are 95.23% and 74.35% (P < 0.01). After 6 months of follow-up visit, the children weight significantly increase in treatment group (P < 0.01). Results indicate that child anorexia granule can facilitate secretion of ghrelin, and inhibit secretion of leptin, so as to work up an appetite. And the molecular mechanism is its infect on serum ghrelin, leptin.

Objective To investigate the feasibility and superiority of local anaesthesia video-assisted thoracoscopic surgery (LA-VATS) in diagnosis and treatment of open thoracic trauma (OTT).Methods Seventy-eight patients with OTT emergently admitted from February 2007 and June 2012 were randomized into LA-VATS group (n =37) and conventional treatment group (n =41) by the toss of a coin.In the LA-VATS group,further treatment was determined following LA-VATS.Volume of chest tube drainage,duration of chest tube placement,average length of hospital stay,and postoperative complications were measured and compared between groups.Results In the LA-VATS group,23 patients completed LA-VATS and 14 were transferred for simple VATS-assisted mini-thoracotomy under general anesthesia.In the conventional treatment group,24 cases completed debridement and chest drainage and 17 cases were transferred for thoracotomy under general anesthesia.Volume of chest tube drainage [(195.0 ± 150.8) ml/d∶ (480.0 ±212.3)ml/d] (t =-2.675,P ＜0.05),duration of chest tube placement [(2.6 ± 1.4) d∶ (3.8 ± 1.9) d] (t =-2.318,P ＜ 0.05),average length of hospital stay [(6.4 ±2.3) d ∶ (10.9 ± 3.3) d] (t =-2.471,P ＜ 0.05),and incidence rate of postoperative complications (10.8％ ∶22.0％) (x2 =4.132,P ＜0.05) were all significantly different between LA-VATS and conventional treatment groups.Conclusion LA-VATS is safe and feasible for diagnostic exploration and simple treatment of OTT.

The present is aimed at identifying the activation of TRAFs in n asopharyngeal carcinoma (NPC) in vitro. The differential expression of TRAF2\,TRAF3 was not detected in RN A and protein level, whereas the expression of TRAF1 in HNE2-LMP1 cell lines wa s much more abundant than that in HNE2 cell lines, suggesting that TRAF1 may be an inducible molecule; More importantly, TRAF1, TRAF2 or TRAF3 were activated in the HNE2-LMP1 cells, whereas TRAF1, TRAF2 or TRAF3 were not activated in HNE2 cells as detected by the immunoprecipitation-Western blotting assay. These data provide an experimental basis for our study beginning from the signal transduca tion pathway for the eluccidation of the mechanism of LMP1 carcinogenesis in NP C.
