Objective To observe the incidence of ciliary detachment and its relationship with intraocular hypotension soon after vitrectomy.Methods A total of 46 eyes of 46 patients who underwent vitrectomy were examined by ultrasound biomicroscope (UBM).The patients were divided into three groups according to different tamponade: gas group (11 eyes),silicone oil group (8 eyes) and balanced saline solution (BSS) group (27 eyes).Basing on the postoperative intraocular pressure (IOP),the patients were divided into two groups: IOP<10 mm Hg (25 eyes) and IOP≥10 mm Hg (21 eyes).UBM was applied to determine the tomographic features of the ciliary body 3 days after the surgery.IOP were monitored by non-contact tonometer daily after the surgery.The eyes with ciliary detachment were then examined once a week till the ciliary detachment reattached.The follow-up period was from 14 to 35 days.Results After vitrectomy,ciliary detachment was observed in 20 eyes of 46 eyes (43.5%),The incidence of ciliary detachment was 27.3% in gas group,25.0% in silicone oil group,and 55.6% in BSS group.The average IOP in eyes with ciliary detachment [(6.47±4.49) mm Hg (1 mm Hg=0.133 kPa)] was significantly lower than that in the eyes without ciliary detaehmen [(15.61±7.72) mm Hg] (t=8.031,P<0.001).The incidence of ciliary detachment was higher in eyes with postoperative IOP <10 mm Hg (68.0%) than that in the eyes with postoperative IOP≥10 mm Hg (14.3%) (χ2=15.60,P<0.001).All eyes with postoperative ciliary detachment got spontaneous reattaehment within 30 days after the surgery except that one eye had optic disc edema due to severe intraocular hypotension.Conelusions Early postoperative ciliary detachment is a common complication after vitrectomy.Eyes filled with BSS have the highest incidence of postoperative ciliary detachment.Most of the patients with ciliary detachment may get spontaneous reattahment within 30 days after the surgery.

With advances in complex network theory, the thinking and methods regarding complex systems have changed revolutionarily. Network biology and network pharmacology were built by applying network-based approaches in biomedical research. The cardiovascular system may be regarded as a complex network, and cardiovascular diseases may be taken as the damage of structure and function of the cardiovascular network. Although Chinese medicine (CM) is effective in treating cardiovascular diseases, its mechanisms are still unclear. With the guidance of complex network theory, network biology and network pharmacology, network-based approaches could be used in the study of CM in preventing and treating cardiovascular diseases. A new discipline-network cardiovasology of CM was, therefore, developed. In this paper, complex network theory, network biology and network pharmacology were introduced and the connotation of "disease-syndrome-formula-herb" was illustrated from the network angle. Network biology could be used to analyze cardiovascular diseases and syndromes and network pharmacology could be used to analyze CM formulas and herbs. The "network-network"-based approaches could provide a new view for elucidating the mechanisms of CM treatment.

Objective To compare the efficacy of pneumatic retinopexy and subretinal drainage in the treatment of primary rhegmatogenous retinal detachment(RD) in scleral buckling procedure.Methods Pneumatic retinopexy or subretinal drainage was applied during the scleral buckling procedure when lots of subretinal fluid existed.Results Twenty-three of 26 eyes(88.5%) were successfully reattached by pneumatic retinopexy during scleral buckling procedure for the repair of primary retinal detachment.New hole formation was the major complication for the surgical failure.One eye was fixed by another buckling procedure and the other two were treated by vitrectomy.Eleven of 12 eyes(91.7%) with primary RD were successfully managed by scleral buckling procedure and subretinal fluid drainage.Subretinal hemorrhage occurred in one eye after subretinal drainage.Conclusion Pneumatic retinopexy can substitute subretinal drainage in the repair of primary rhegmatogenous retinal detachment when plenty of subretinal fluid exists.

Objective To compare the anatomic and functional results of ocular intensive and systemic corticosteroid administration prior to vitrectomy for primary rhegmatogenous retinal detachment with choroidal detachment.Methods A retrospective,clinical pilot study.Results Of 38 cases of primary rhegmatogenous retinal detachment with choroidal detachment,11 cases received intensive 1% prednisolone acetate eyedrops once each hour,totally 16 times a day(Group A)for(4.91?1.51)days and 27 cases received systemic corticosteroid treatment which is performed as intravenous injection of 15 mg Dexamethasone for 3 d and then taped down for(5.67?1.88)days prior to vitrectomy(Group B).The rate of anatomic reattachment by one operation was 54.5% for Group A and 63.0% for Group B;The rate of reattachment by reoperation was 80% for Group A and 100% for Group B.The functional result was the same in the two groups,with the vision improvement in 70% cases of Group A and 68% cases of Group B.The minimal follow-up period was 3 months after final operation.Conclusion There is an obvious tendence of lower rate of anatomic reattachment in intensive steroid eyedrops treatment group than in systemic corticosteroid treatment group.However,the functional result is almost the same in the two groups.

Objective To investigate the preventive effect of psychological intervention combined with cod liver oil ointment on radiation nasal inflammation in nasopharyngeal carcinoma patients. Methods 90 patients with nasopharyngeal carcinoma treated in our hospital from January 2015 to December 2016 were randomly divided into study group and control group. The control group was treated with nasopharyngeal irrigation. The study group was given psychological intervention combined with cod liver oil ointment. Results The treatment effect of the study group was significantly better than that of the control group, and the incidence of radiation rhinitis was significantly lower than that of the control group. There was no significant difference between the two groups before the endoscopic score, the CT score of the sinus and the cilia transmission rate Improved, the study group was significantly better than the control group(P<0.05); before treatment, the two groups of patients with no significant differences in clinical symptoms, after treatment have been improved, the study group was significantly better than the control group(P<0.05). Conclusion The application of psychological intervention combined with cod liver oil ointment in radiotherapy of nasopharyngeal carcinoma is beneficial to prevent radiation rhinitis and improve the function of sinus function.

Primary open angle glaucoma (POAG) is a group of disorders characterized by loss of retinal ganglion cells (RGCs) associated with optic nerve degeneration and visual field damage.With the application of molecular biology in ophthalmology,at least 20 chromosome loci have been identified to be linked to POAG.Only 3 causative genes were identified from these loci,i.e.myocilin (MYOC),optineurin (OPTN) and WD repeat domain 36 (WDR36),which altogether account for less than 10％ of POAG.Only a portion of POAG Complies with Mendelian inheritance,and a considerable fraction results from a large number of variants in multiple genes,each contributing less effects.The main technological approaches include family linkage analysis,genome-wide scan,casecontrol association study,etc.Association studies found at least 16 genes to be related to POAG,but reports on glaucoma-causing effects of these genes are conflicting.In this article,we reviewed the POAG related genes,especially the four well known causative genes of MYOC,OPTN,WDR36,and CA V1/CA V2,in terms of their locations,structures,functions,and mutations.

The systemic anaphylaxis murine model was induced by the injection of oval albumin (OVA)in aluminum hydroxide gel adjuvant. The death rate varied with the mouse species: 40-90% in Swiss and 69% in average,no death in C57BL/6 and 615 but some symptoms. developed. Swiss mice was adopted in this experiment.90% of mice pretreated with Lx remained living after allergen challenge,but only 20% in normal control. For elucidation the possible mechanism of Lx action,the study was carried out on detection of anti-OVA IgE specific antibody and histamin concentration in lung tissues. Passive cutaneous anaphylaxis(PCA)titers for anti-OVA IgE antibody in serum ranged from undilution to 160 in control group and not detectable in group pretreated with Lx. In addition, after absorption of PCA positive sera with anti-IgG antibody.the PCA activity was not affected. Histamin content was 1.54?0.24?g/ml in Lx treated mice caopared to 2.69?0.67?g/ml in control group(p

Objective: To investigate the relationship between electrophysiology and pathology changes in diabetic peripheral neuropathy (DPN) rats and to assess the value of electrophysiology in diagnosis of DPN. Methods: Twenty-four healthy male SD rats were intraperitoneally injected with a single dose of streptozotocin to induce DPN models and the rats were subsequently divided into 3 groups, namely, the DPN model group, the low dose Tong-Luo composite recipe (TLCR) group, and the high dose TLCR group. Rats in the latter 2 groups were lavaged with 2 ml double-distilled water containing 0.5 g/kg and 2 g/kg TLCR for 8 weeks, respectively. Another 8 healthy rats were taken as normal controls. The motor conduction velocity (MCV), sensory conduction velocity (SCV), and potential latency and amplitude of caudal nerves were measured after 8 weeks in all rats. Morphometric quantitative analysis was also performed. Results: Compared with normal control group, the MCV, SCV, and potential amplitude of the caudal nerve in DPN model group were decreased, but the potential latency was increased. After TLCR treatment, the above indices were significantly improved and were close to those of the normal control group. SCV of the low dosage group was still significantly lower than that of normal control group (P< 0.05), that of high dose group was also lower than that of normal control group but with no statistical significance, and that of low dose group was significantly low than that of high dose group (P<0.05). Pathological examination showed that the myelinated nerve fiber positive area, myelin sheath area, and axon area in DPN model group were lower than those in the normal control group, the areas in treatment group were obviously increased compared with DPN model group. Compared with the low dose group, the high dose group had significantly larger myelinated nerve fiber positive area and myelin sheath area, but not axon area. The changes of the myelinated nerve fiber positive area and myelin sheath area were basically consistent to SCV changes in all groups, but the myelin sheath area of the high dose group were still smaller than that of the normal control group (P<0.05). Conclusion: Myelinated nerve fiber positive area and myelin sheath area are the more sensitive markers of the course and therapeutic outcome of DPN. SCV can be used for initial estimation of myelinated nerve fiber density. SCV is closely related to the pathological changes of myelin sheath and can be used for clinical diagnosis of DPN, but should be reserved for patients with suclinical DPN and patients who have received high dose drug treatment.
