1.The advances of lens extraction for primary angle closure glaucoma
Chinese Journal of Experimental Ophthalmology 2012;30(8):761-764
Development of primary angle closure glaucoma (PACG) is closely related to the changes of the position and morphology of the lens owing to a shallow anterior chamber,pupillary blockage and angle closure.Lens extraction can deepen the depth of the anterior chamber and resolve the pupillary blockage,and therefore increase the outflow of aqueous fluid.Furthermore,the combination of lens extraction with goniosynechialysis can reopen the closed anterior chamber angle and relieve peripheral anterior synechia of pupil,with a better clinical effectiveness for primary angle closure glaucoma.Recently,the studies related to lens extraction for primary angle closure glaucoma have madc great progression,especially its mechanism and efficacy,and of course some existing problems of lens extraction are concerned.In this review,the relationship between lens and primary angle closure glaucoma,the clinical effectiveness of lens extraction for primary angle closure glaucoma,the safety evaluation of lens extraction and goniosynechialysis were summarized.

Chronic prostatitis is a common male disease, and its pathogenesis is not yet clear. Most scholars believe that oxidative stress and immune imbalance are the keys to the occurrence and progression of chronic prostatitis. Currently immunotherapy of chronic prostatitis remains in the exploratory stage. This article relates the active ingredients of 5 Chinese medicinal herbs (total glucosides of paeony, tripterigium wilfordii polglycosidium, curcumin, geniposide, and quercetin) for the treatment of chronic prostatitis and their possible action mechanisms as follows: 1) inhibiting the immune response and activation and proliferation of T-cells, and adjusting the proportion of Th1/Th2 cells; 2) upregulating the expression of Treg and enhancing the patient's tolerability; 3) suppressing the activation of the NF-kB factor, reducing the release of iNOS, and further decreasing the release of NO, IL-2 and other inflammatory cytokines, which contribute to the suppression of the immune response; 4) inhibiting the production of such chemokines as MCP-1 and MIP-1α in order to reduce their induction of inflammatory response. Studies on the immune mechanisms of Chinese medicinal herbs in the treatment of chronic prostatitis are clinically valuable for the development of new drugs for this disease.

AIM: To assess the changes of macular thickness of acquire immunodeficiency syndrome ( AIDS) patients.
METHODS:The study based on the data analysis of 38 human immunodeficiency virus ( HIV ) positive patients ( 64 eyes ) . According to CD4 count and whether cytomegalovirus retinitis ( CMVR) happened, the patients were divided into 3 groups. Group A included 16 patients (32 eyes), in which CD4 count was < 50cells/μL and CMVR did not happen. Group B included 10 patients ( 20 eyes), in which CD4 count was>50cells/μL and CMVR did not happen. Group C included 12 patients (12 eyes), in which CD4 count was < 50cells/μL and CMVR just happened. Group D included 10 healthy people ( 20 eyes ) , as normal control group. By using optical coherence tomography ( OCT ) , thickness of retina along with a 1mm diameter circle centered on macular was evaluated.
RESULTS:The mean foveal thicknesses in groups A, B, C and D were 254. 03±15. 63μm, 263. 11±17. 12μm, 304. 50±50. 62μm and 257. 64±8. 54μm in order. Compared with foveal thickness in each group, there were significant differences in general (F=12. 933, P=0. 000). The mean foveal thickness in groups CMVR increased, which was of significant difference (P= 0. 000), compared with other groups.
CONCLUSION: CMVR can impair the structure and function of macular, which then seriously affects the visual function of patients. It's helpful to understand the progress and prognosis of CMVR disease by observing macular structure with OCT in early time.

OBJECTIVE:To observe the clinical efficacy and safety of different doses of atorvastatin in the treatment of chron-ic subdural hematoma(CSDH). METHODS:One hundred and tweaty-eighie CSDH patients selected from our hospital during Jun. 2013-May 2015 were divided into observation group(n=62)and control group(n=66)in accordance with random number table. Both groups were given conventional treatment of brain cell nutrition. Control group received Atorvastatin tablet 20 mg,po,qd;observation group received Atorvastatin tablet 40 mg,po,qd. Both groups were treated for 6 months. Clinical efficacy,CSS and ADL score,hematoma volume,the levels of serum inflammatory factors (hs-CRP,MMP-9,IL-6,TNF-α) were observed in 2 groups. ADR was recorded during treatment and recurrence rate was also recorded. RESULTS:2 patients withdrew from observa-tion group and 6 from control group. Finally,120 patients met the criteria were included,with 60 cases in each group. Total re-sponse rate of observation group(88.3%)was significantly better than that of control group(73.3%),with statistical significance (P<0.05). After 1,3,6 months of treatment,CSS score,hematoma volume,the serum levels of hs-CRP,MMP-9,IL-6 and TNF-α in 2 groups were significantly decreased,while ADL score was increased significantly;the improvement of above indexes in observation group was significantly better than in control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). The recurrence rate of control group(13.3%)was significantly higher than that of observation group(3.3%),with statistical significance(P<0.05). CONCLUSIONS:Daily dose of shows ator-vastatin 40 mg better therapeutic efficacy and lower recurrence rate in the treatment of CSDH with good safety.

The ideal treatment and recovery of osteoarticular injury remain to be resolved. Small intestinal submucosa (SIS), a naturally-occurring decellularized extracellular matrix, has been recognized as an ideal scaffold for tissue engineering and widely used in repairing various tissues and organs. Nowadays its application has also been gradually increased in the field of orthopedics. We reviewed laboratorial studies and clinical trails about the application of SIS in bone and joint repair, aiming to evaluate its effects on the repair of bone, cartilage, meniscus, ligament and tendon. SIS has showed promising results in repairing bone, meniscus, ligament or tendon. However, additional studies will be required to further evaluate its effects on articular cartilage and tendon-bone healing. How to optimize SIS material,is also a focused problem concerned with making SIS a potential therapeutic option with high value for orthopedic tissue repair.

OBJECTIVETo observe the efficacy and safety of Qizhi Jiangtang Capsule (QJC) in treating stage 3b diabetic kidney disease (DKD) patients with macroalbuminuria.
METHODSPatients who conformed to the diagnostic criteria of stage 3b DKD were randomly assigned to two groups according to random digital table, the experiment group and the control group, 84 in each group. All patients received a two-week elution period, and then were treated with basic Western therapy. Patients in the experiment group took QJC, 5 pills per time, 3 times a day, while those in the control group took Valsartan Capsule 160 mg each time, once daily. The observation period of follow-ups was limited within 6 months, and the time points were set as the baseline, 1st month, 3rd month, and 6th month. Systolic blood pressure (SBP), diastolic blood pressure (DBS), 24 h urine protein quantitative (24 h UPQ), plasma albumin (ALB), and serum creatinine (SCr) were detected and recorded, and estimated glomerular filtration rate (eGFR) was calculated. The occurrence of hypoglycemic reaction, coagulation disorder, gastrointestinal tract reaction, allergy, hyperkalemia, doubling of creatinine, and overall adverse events were observed and recorded at same time.
RESULTSFinally 81 patients in the experiment group and 80 patients in the control group were effectively included. Compared with the baseline level, SBP and DBS obviously decreased in the control group at month 1 of treatment (P < 0.05), and more significantly decreased at month 6 of treatment (P < 0.01). SBP at month 1, 3, and 6 of follow-ups; DBS at month 6 of follow-ups was lower in the control group than in the experiment group (P < 0.05). At month 1, 3, and 6 of follow-ups, 24 h UPQ of the experiment group was significantly lower than the baseline level (P < 0.01). It was also significantly lower than the level of the control group at the same time point (P < 0.05). There was no significant difference in 24 h UPQ at month 1, 3, and 6 of follow-ups between the control group and the baseline level (P > 0.05). ALB of the experiment group showed an increasing trend. It was significantly higher than the baseline level at month 6 (P < 0.05), which was also higher than that of the control group at same period (P < 0.05). There was no significant difference in the ALB level in the control group (P > 0.05). SCr of two groups showed an increasing trend. SCr of the experiment group was significantly higher at month 1, 3, and 6 follow-ups than the baseline level (P < 0.05). But the increment of SCr was higher in the control group than in the experimental group, and obviously higher than the baseline levels (P < 0.05). eGFR of both groups showed a decreasing trend. The decrement was higher in the control group than in the experimental group (P < 0.05). The proportion of progression of renal functions at month 1, 3, and 6 of follow-ups in the experimental group was 0.0% (0 case), 9.55% (8 cases), and 21.4% (18 cases), while they were 8.3% (7 cases), 21.4% (18 cases), and 40.5% (34 cases) in the control group. There was no statistical difference in the proportion of progression of renal functions between the two groups at month 3 and 6 of follow-ups (P < 0.05). There was no statistical difference in the incidence of adverse reactions between two groups (P > 0.05).
CONCLUSIONQJC could effectively reduce urinary protein of patients with stage 3b DKD, and delay the progression of renal functions.
