AIM: To discuss the effects of preoperative vitreous cavity injection of ranibizumab on 25G minimally invasive vitreoretinal surgery (VRS) in patients with proliferative diabetic retinopathy(PDR).METHODS: From February 2013 to December 2015,74 patients with PDR received VRS (82 eyes) were retrospectively analyzed.Patients were divided into VRS + IVR group and VRS group according to preoperative VRS treatment.VRS+IVR group: preoperative injection of ranibizumab (10mg / mL) at 3-5d before operation;VRS group: VRS only.We recorded VRS operation time,filling situation,iatrogenic retinal hole and so on.RESULTS: The operation time and coagulation times of VRS+IVR group were significantly lower than VRS group.The two groups in operation time and coagulation times were statistically significant (all P<0.05).In the VRS+IVR group,the number of cases of iatrogenic retinal hole and the use of silicone oil were lower than those of VRS group,the difference between the two groups was statistically significant (P<0.05).While the use number of C3F8 and perfusion fluid were not statistically significant (P>0.05).In VRS-IVR group within 3mo after operation,4 eyes appeared to vitreous body hematocele,VRS group was 13 eyes,the difference was statistically significant (x2=4.966,P<0.05).CONCLUSION: PDR patients with 25G minimally invasive VRS with preoperative therapy can reduce postoperative ocular bleeding,rate of retinal injury and silicone oil filling,shorten the operation time,the incidence rate and improve the success rate of surgery and reduce eye bleeding,postoperative complications such as adhesion.

OBJECTIVETo observe the effect of jujube pretreatment on serum levels of AST and ALT, liver pathology, and the expression of cytochrome P4502e1 (CYP2E1) and tumor necrosis factor-alpha (TNF-alpha) in the liver tissue of alcoholic liver disease (ALD) mice.

METHODSTotally 88 Kunming mice were randomly divided into the control group (n = 28), the model group (n = 32), and the jujube treatment group (n = 28). The animal model was prepared using intragastric alcoholism for mice in the model group and the jujube treatment group, while distilled water was intragastrically given to those in the control group. Extraction of jujube was intragastrically given to mice in the jujube treatment group at week 4, while equal volume of distilled water was intragastrically given to mice in the rest two groups. The therapeutic course lasted for 12 weeks. Serum levels of AST and ALT, liver pathology, and the expression of CYP2E1 and TNF-alpha in the liver tissue of ALD mice were observed after administration of jujube.

RESULTSCompared with the model group, serum levels of AST and ALT decreased, the liver pathology was improved, and the expression of CYP2E1 and TNF-alpha in the liver tissue decreased, showing statistical difference (P < 0.05).

CONCLUSIONJujube had certain effect in treating ALD.

The modernization strategy of traditional Chinese medicine (TCM) has been implemented for 20 years, which has provided a strong impetus to the development of TCM and gained remarkable achievements in scientific research platform, research result, industry scale, clinical evaluation, internationalization and professionals training as well. The achievements of TCM modernization greatly improved the clinical service ability and level of TCM, broadened the scope of service, become the important foundation of the big health industry. TCM has played an irreplaceable role in the health care reform, benefiting people's livelihood, promoting industrial structure adjustment and cultivating strategic emerging industries. This article summarized the main achievements of the modernization of TCM and prospected the direction and tasks in the next 20 years in order to further promote the modernization process of TCM.

[Objective]To explore the effective treatment method of the articular fracture in distal radius.[Method]Severely comminuted AO type-C3 intra-articular fractures of the distal end of the radius were treated with combined internal and external fixation.The Gartland and Werley system and the Green and O'Brien system were used for comparison of the pre-operative and after operative evaluation.Total articular congruity had been assessed with both clinical rating systems.[Result]At a mean of ninteen months following-up,the mean arc of flexion-extension was 78% of that on the uninjured side and the mean grip strength was 82% of that on the uninjured side.The mean total articular incongruity(the gap plus the step-off)averaged 2 mm,and the radial length was restored to a mean of 11 mm.According to the Gartland and Werley demerit-point system,seventeen of the patients had a good or excellent result.According to the modified Green and O'Brien clinical rating system,eleven had a good or excellent result.Postoperative total articular incongruity had a moderately strong correlation with the outcome as assessed with both clinical rating systems.[Conclusion]Open reduction and combined internal and external fixation of AO type-C3 fractures can restore radiographic parameters to nearly normal values,maintain reduction throughout the period of fracture-healing,and provide satisfactory functional results.

BackgroundThere are a lot of studies about the wound healing charateristics of cornea after SBK with femtosecond laser.In our study,mechanical microkeratome was preferred for corneal flap.We observed the proliferation of keratocytes by investigating the myofibroblast ( MF) activity.Objective The study was to compare the morphologic and histological changes in the cornea after sub-Bowmans keratomileusis ( SBK) with photorefractive keratectomy ( PRK) and laser in situ keratomileusis ( LASIK)by investigating the express of transforming growth factor-β( TGF-β)and α-smooth muscle actin( α-SMA)and to investigate the wound healing characteristiCs of cornea after SBK.MethodsTwenty-seven adult New Zealand white rabbits were randomly assigned into group A,B and C.SBK waa performed on the right eyes of each rabbit in group A,LASIK for group B and PRK for group C.All the left eyes were used as the normal control group.Histological examinations by light microscopy were performed on day 7,1 months,3 months after surgery.The expression of α-SMA and TGF-β and the number of activated MF were assessed by immunohistochemiatry.ResultsIn SBK group,corneal epithelium cells proliferation around the wound was seen and the numbers of active fibroblasts were increased after surgery.The expression of α-SMA or TGF-β around the corneal flap and the corneal 8troma started at day 7 postoperatively and peaked at 1 months and decreaaed around the corneal flap and the corneal 8troma started at day 7 postoperatively and peaked at 1 months and decreaaed t3mnh.TFβep( SBK:t=2.226,2.158,2.330,P＜0.05;PRK:t=4.745,6.524,6.293,P＜O.05).The numbersof activ( SBK:t=2.226,2.158,2.330,P＜O.05;PRK:t=4.745,6.524,6.293,P＜0.05).The numbersof activatedMFs were different fromLASIKstatisticallytoobetweenSBKgroupandPRKgroup ( SBK:t =4.439.5.692,4.175,P＜0.05 ; PRK:t=6.330,6.723,5.267,P＜0.05 ).Theα-SMAand TCF-βexpressionsin SBKgroupwerelessthan PRK group but more thanLASIKgroup( TCF-β:t =4.691,5.527,t =4.399,P＜0.05 ; α-SMA:t =9.637.10.282,8.197,P＜0.05).The numhers of MFs in SBK group was less than PRK group before 3 months and were same at 3 months ( t =5.188,4.529,P＜0.05 ).Conclusions ComparedwithconventionalLASIK,SBKcanup-regulatethe expression of α-SMA.TGF-β,activated MFs in the corneal flap.which enhance corneal biomechanics and promote healing.However,most of the disadvantages caused by wound healing in SBK still remain compared to PRK.
