Conclusion Proton pump inhibitor combined with Clostridium butyricum lactobacillus tablets has good curative effect and highly HP eradication rate on treatment with HP type peptic ulcer patients.

Percutaneous neprolithotomy (PCNL) is the preferred method for the treatment of the majority of urinary calculi, especially for the calculi lies in the renal and upper ureteral.Recently, a number of trials were applied into TPCNL, such as, decrease the nephrostomy and indwelling externally grooved ureteral stent, internal ureteral catheter and not aiming replace the preventive use of renal tube.TCNL has its advantages in postoperative pain, hospitalization time and postoperative recovery than standard percutaneous neprolithotomy.

Objective:To analyze the reasons for the failure of scleral buckling (SB) in the treatment of rhegmatogenous retinal detachment, and observe the efficacy and safety of re-buckling.Methods:This was a retrospective non-comparative clinical research. From July 2014 to June 2020, patients with first-time SB failure who visited the Beijing Tongren Hospital were included in this study. There were 42 patients, including 30 males and 12 females, with the average age of 29.40±16.13 years, and they were all monocular. The retinal detachment range <1, 1-2 and > 2 quadrants were 9, 22 and 11 eyes, respectively. The macula was involved in 38 eyes. The average logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity (BCVA) was 0.99±0.57. Forty eyes and 2 eyes were performed 1 and 2 SB, and all the retina were not reattached. All patients were under general anesthesia, according to the conditions during the operation, re-freeze and located the holes under indirect ophthalmoscope. And selected the new external pressure material or retained the old one in combination with the other operations to reattaced the retina. The average follow-up time was 31.93±18.97 months. The reasons for the failure of the first surgery based on the records of this surgery were analyzed. The visual acuity changes, the rate of retinal reattachment and the occurrence of complications were observed. The visual changes were compared by paired t test. Results:The top three reasons for the failure were: 16 case of the displacement of the compression spine (38.10%); 9 cases of missing the retinal holes and 9 case of improper selection of compression substances (account for 21.43%, respectively); 6 cases of insufficient height of compression spine (14.29%). All of retina were reattached (100%, 42/42). The average logMAR BCVA was 0.52±0.40. The difference of logMAR BCVA between before and after surgery was statistically significant ( t=6.106, P=0.000). There were a slight increase in intraocular pressure in 8 eyes, the average intraocular pressure was 25.00±2.61 mmHg (1 mmHg=0.133 kPa). No serious complications occurred after surgery. Conclusions:The position deviation of the compression spine, the missed hole during the operation, the improper selection of external compression material, and the insufficient height of the compression spine are the main reasons for the failure of SB. After adjusting the reasons for the failure, there is still a higher rate of retinal reattachment.

Objective To investigate the effects of comprehensive intervention on population death rate. Methods To analyze population crude death rate, cause-specific death rate, and compare the death rate in intervention group with that of control.Results The average crude death rate in communities of Changsha was 617 79 per 100 000, with 557 27 per 100 000 of standarized death rate. Cerebrovascular disease, cardiocascular disease, tumour, disease of respiratory system injury and intoxication were from the first rank to the fifth in order the death causes. The death rate in intervention group was lower than that of control group significantly, and the death rate of cerebrovascular disease and cardiocascular disease in intervention group were lower than that of control significantly.Conclusions Cerebrovascular disease and cardiocascular disease are the major causes of death. Intervention on risks factors of cardio- and cerebrovascular diseases can lower the death rate of cardio- and cerebrovascular diseases and the population death rate.

Objective To detect the level of serum melanoma-inbibiting activity (MIA) in patients with uveal melanomas, and investigate the value of MIA in diagnosing and inspecting uveal melanomas. Methods Enzyme-linked immunosorbent assay (ELISA) was used to detect the concentrations of MIA in peripheral serum of 27 patients with uveal melanoma, 6 with melanocyte tumor, 7 with other ocular tumors and 16 healthy individuals, respectively. Results The concentration of MIA in patients with uveal melanoma was significantly higher than that in the healthy ones (16 individuals) and the patients with adenoma of non pigmented ciliary epithelium (4 patients), retinoblastoma (2 patients), and retinal angioma 91 patient). The concnetration of MIA in patients with uveal melanoma without scleral infiltration or remote metastasis was obviously lower than that in the patients with scleral infiltration or remote metastasis, but didn′t differ much from which in the patients with melanocyte tumor. In the patients with uveal melanoma without infiltration or remote metastasis, there was no significant difference of MIA level between patients with spindle cell and mixed and epithelioid cell. Conclusion The level of serum MIA may be an effective index in diagnosing uveal melanoma, which can monitor the metastasis of uveal melanoma.

Objective To investigate retrospectively the clinical characteristics of hospitalized ulcerative colitis(UC)patients of our department,and evaluate the diagnosis and treatment.Methods The cases of UC patients from 1989 to Jun 2005 were retrospectively reviewed. We analyzed the patients' symptoms,diagnosis,and treatment.Results There were 155 cases reviewed. The sex ratio(M/F)was 1.54∶ 1. The average age of patients was 41.8. The peak age of onset was 20~30. 32.3% of our cases were mild type,and 41.3% were moderate type,severe type were 26.5%. Of these pateints,52.9% were pancolitis,and 39.4% were chronic recurrent type,which was very common. Most cases(72.9%)were diagnosed by clinic combined with endoscope and pathology. Most of the severe UC responded well to the drug therapy. Very less(4.5%)had to underwent surgery. No patient died.Conclusion Most of our patients are mild or moderate type,and they respond well to drug some severe and moderate types need steroids and immuno suppressor. The extracolonic manifestation rate(12.9%)and operation rate(4.5%)are low.

Background Choroidal neovascularization (CNV) is a major cause of visual loss in many fundus diseases.Fundus angiography (FA) is essential for the diagnosis,location and treatment of CNV.However, FA is an invasive examination method.Split spectrum amplitude decorrelation angiography (SSADA) OCT can quickly and clearly provide vascular signals.However, whether SSADA-OCT is feasible in the evaluation of CNV remains unclear.Objective This study was to detect and quantify CNV using OCT angiography.Methods Thirteen patients with unilateral CNV were included in Beijing Tongren Eye Center from June 2014 to August 2014.All affected eyes of the subjects were scanned with a high-speed frequency domain OCT.The SSADA-OCT images were obtained by scanning of macula covered 6 mm×6 mm area.The CNV area and grey scale were computed from the en face OCT images of retinal layer and choroidal layer.This study followed the Helsinki Declaration and was approved by the Ethics Committee of Beijing Tongren Hospital,and written informed consent was obtain from each patient prior to any medical examination.Results SSADA-OCT angiogram revealed CNV area and location confirmed by fluorescein angiography,and the CNV blood flow information of internal limiting membrane,inner plexiform layer,retinal pigment epithelium,and choroid was exhibited by OCT angiography.All CNVs with different causes showed the well defined and hyperreflected signal in macular region.The average CNV area was (0.15 ±0.09)mm2 , and the average grey scale of CNV was 75.40±32.35 in the affected eyes,and that in the contralateral eyes was 26.99±22.87 in the 300 μm area,showing significant elevation in gray scale in the affected eyes compared with the contralateral eyes (t =6.946, P＜0.001).Conclusions OCT angiography is a noninvasive observation technique of retinal and choroidal blood flow.It can provide quantitative information and detailed images of CNV.

Background Cystoid macular edema (CME) is caused by many fundus diseases.The noninvasive clinical diagnosis methods for CME are conventional color fundus photography up to now.However,these images can not display the CME range well.Confocal scanning laser ophthalmoscope (cSLO) based retinal imaging can provide clear picture with high contrast.However,whether cSLO imaging is feasible in the quantitative assessment of CME remains unclear.Objective This study was to image the boundary of CME and assess the quantification of CME image from cSLO imaging technology.Methods A series case-observational study was designed.This study protocal was approved by Ethic Committee of Beijing Tongren Hospital.cSLO based retinal imaging technology was carried out on consecutive 24 eyes of 24 patients with clinically diagnosed and OCT confirmed CME in Beijing Tongren Eye Center from August to December 2015 under the informed consent of each individual.The radial scan range was 45°× 45 ° and the line scan level was 49 at macula area.The pseudocolar image,green light reflective image (532 nm) and infrared reflective image (785 nm) were collected.The imaging was analyzed by EasyScan software (version 1.2.2).Fundus color photography and SD-OCT were carried out in each patient.The images were graded by specialists according to the SD-OCT cross sectional results.Results The primary causes of CME included epiretinal membrane (10 eyes),branch retinal vein occlusion (BRVO) (6 eyes),central retinal vein occlusion (CRVO) (4 eyes),diabetic retinopathy (DR) (3 eyes) and CRVO with BRVO (1 eye).A CME image was exhibited on the fundus color photogram with the obscure boundary;while the clear range of CME was displayed by the cSLO imaging.The mean score of CME from pseudocolar image,green light reflective image and infrared reflective image was 3.21±0.78,2.67±0.96 and 2.54±0.83,respectively,which was significantly higher than 1.33±0.82 from the fundus color photography (all at P＜0.01).Conclusions In CME patients,the imaging quality from cSLO-based retinal imaging technology is better than that from traditional fundus color photography.Combined with SD-OCT sectional scan analysis,cSLO-based retinal imaging technology may offer a method to observe and record more fundus details for CME diagnosis.

Objective To study the expressing status of antisense tissue inhibitor of metalloproteina se-1(TIMP-1) in hepatic stellate cells (HSC) constructed in vitro, and to eval u ate the effects on the production of type Ⅰ and Ⅲ collagens secreted by activated rat HSC. Methods HSC were extracted from normal rat liver by pronase and co llagenase digestion and purified by centrifugal elutriation, and were cultured pla stic until they were activated to a myofibroblastic phenotype after 7-10 days. RT-nest-PCR and gene recombinant techniques were used to construct the rat ant isense TIMP-1 expression plasmid which can express in eukaryotic cells, and seg uenced after being counstructed. The expressing plasmid and the pcDNA3 empty pla smid were transfected into HSC by Effectene reagent separately. The cells were sel ected after growing in DMEM containing 400 ?g/ml G418 for 3 to 4 weeks. Exp ression of TIMP-1 in HSC was d etermined by Northern blot and Western blot. We tested the interstitial collagen ase activity in culture media with FITC-labled type Ⅰ collagen as substrate. U ltimately, we quantified the typeⅠ and type Ⅲ collagen in HSC by Wester n blot. Results The exogenous antisense TIMP-1 recombinant plasmid could block the expression of TIMP-1 greatly, while there were not the same outcome i n pcDNA3 empty plasmid g roup and non-transfecting control group. The ratio of TIMP-1/GAPDH was 0.67, 2 .41 and 2.97 respectively at mRNA level( P

Objective To study the effects of hirudo extract liquor(HEL) on the expressions of HSP70 and TGF?-1 in intracerebral perihematoma tissues of rats.Methods We established the experimental ICH models in Wistar rats by stereotaxical injecting quantitative collagenase(0.7 U collagenaseⅦ) into their left caudate nuclei.The rats continued to be treated with HEL(treatment group) or normal saline(control group) through intravenous injection by vena caudalis and the scores of neurologic impairment in two groups were evaluated every day.The slices of these samples at 3rd,6th and 10th day were stained by immunohistochemistry and the positive cells of HSP70 and TGF?-1 were counted by image analysis system,respectively.Results The scores of neurologic impairment in two groups were remarkably reduced with time going((P
