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 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 observe the effects of recipe for invigorating kidney on expression of estrogen receptors in ovariectomized rats. METHODS: The rats, which were given high-cholesterol diet after ovariectomy, were chosen as experimental subjects. After fed kidney-invigorating recipe for 16 weeks, the rats were killed and the levels of serum lipid and estradiol of these rats were examined. The expressions of estrogen receptor alpha and beta mRNAs in aorta, pituitary gland and hypothalamus, and the affinity of estrogen receptor-ligand were also detected. RESULTS: The kidney-invigorating recipe could increase the expression levels of estrogen receptor alpha and beta mRNAs in different parts such as aorta, pituitary gland and hypothalamus, and enhance the affinity of estrogen receptor-ligands. CONCLUSION: The recipe for invigorating kidney may meliorate atherosclerosis in ovariectomized rats by regulating the estrogen receptors.

Objective To study the efficacy of arthroscopic reconstruction of anterior cruciate ligament(ACL)with hamstring tendons and button-suture plate.Methods Thirty-two cases of ACL rupture received arthroscopic reconstruction with hamstring tendons and button-suture plate.The Lachman test and Pivot shift test were performed before and after operation to assess the stability of the knee joint.The knee function was evaluated according to Lysholm rating scale.Regular MRI,anterioposterior and lateral films of knee joint,patella axial radiography were conducted before the operation,to exclude the possibility of osteal avulsion at both ends of ACL.Results The 32 cases were followed for 3.5-29 months,in which 25 cases were more than 12 months.The knee stabilities of all cases recovered.The preoperative Lachman test results were positive in 32 cases,and the Pivot shift test results were positive in 28 cases.Lysholm rating score was 51.8?5.6.The postoperative Lachman tests result were negative in 30 cases,and weakly positive in 2 cases.The Pivot test showed negative results in all the cases.The Lysholm rating score was increased to 90.7?2.5 after the operation.Three cases experienced joint effusion and were treated with puncture aspiration.Conclusions The short-term clinical effect of arthroscopic reconstruction of ACL with hamstring tendons and suture plate is favorable.

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 evaluate the clinical outcome of severe ulcerative colitis(UC)and to find the factors related to treatment and outcome.Methods Forty one hospitalized patients with UC during 1988-2004 were retrospectively reviewed.Data were recorded including the onset,symptoms,signs, laboratory,endoscopic,radiologic and pathologic findings,as well as the processes of clinical treatment. The patients who undergone surgery were also analysed.Results Forty one of 144(28.5%)hospital ized patients were suffered from severe UC,and among them 92.7%(38/41)had pancolitis.The patients who had first onset,chronic persistent,chronic recurrent type were account for 36.9%(15/41),36.9%(15/41) and 26.8%(11/41),respectively.The steroids treatment played the main role in the inducing remission of severe UC(61.0%).Thirty one cases(75.6%)could be relieved by drug therapy.Seven cases(17.1%) were progressed to have operation.The age of early onset,pancolitis,low hemoglobin and serum albumin levels and need of intravenous steroids treatment were associated with the need of surgery.Conclusions Most of the severe UC patients respond well to the medical therapy,but for some non-responding or steroids depending individuals,after a reasonable duration of treatment,surgery should be considered.

Objective To study the effect of bacillus licheniformis and live combined bifidobacterium and lactobacillus on chemotherapy-induced diarrhea (CID). Methods Seventy-two gastric cancer patients with CID were collected and the clinical data were analyzed retrospectively. The patients were divided into 4 groups according to different treatment methods with 18 cases each. The patients in group A were treated with montmorillonite powder, the patients in group B were treated with montmorillonite powder and bacillus licheniformis, the patients in group C were treated with montmorillonite powder and live combined bifidobacterium and lactobacillus, and the patients in group D were treated with montmorillonite powder, bacillus licheniformis capsule and live combined bifidobacterium and lactobacillus. The patients with severe diarrhea in 4 groups were treated with rehydration, maintaining water and electrolyte balance and nutritional support. The Karnofsky performance scale score (KPS score), diarrhea grading before and after treatment and treatment effect were recorded. Results The KPS score after treatment in group A, group B, group C and group D were significantly higher than that before treatment: (70.6 ± 10.6) scores vs. (62.2 ± 12.2) scores, (76.1 ± 7.8) scores vs. (61.7 ± 9.9) scores, (77.2 ± 7.5) scores vs. (61.1 ± 10.8) scores, (83.9 ± 5.0) scores vs. (63.9 ± 10.9) scores. Moreover, The KPS score in group B, group C and group D were significantly higher than that in group A, the KPS score in group D was significantly higher than that in group B and group C, and there were statistical differences (P<0.05). The diarrhea grading after treatment in 4 groups were improved compared with that before treatment. Furthermore, the diarrhea grading in group B, group C and group D were significantly better than that in group B and group C, and there were statistical differences (P<0.05). In group A, there were 2 cases with excellent effect, 10 cases with effect and 6 cases with no effect;in group B, there were 8 cases with excellent effect, 8 cases with effect and 2 cases with no effect;in group C, there were 7 cases with excellent effect, 9 cases with effect and 2 cases with no effect; in group D, there were 9 cases with excellent effect, 9 cases with effect and 0 case with no effect. The treatment effect in group D was significantly better than that in the other 3 groups, and there were statistical differences (Hc = 10.81, P<0.05). Conclusions Bacillus licheniformis and live combined bifidobacterium and lactobacillus is more effective in the treatment of gastric cancer patients with CID.
