Objective To investigate the Helicobacter pylori (HP) infection in the clinical curative effect of peptic ulcer patients using proton pump inhibitor combined with Clostridium butyricum live bacteria treatment. Methods 112 cases of peptic ulcer patients with Helicobacter pylori infection were randomly divided into two groups, the study group used proton pump inhibitor combined with Clostridium butyricum lactobacillus tablets treatment, the control group only used proton pump inhibitor treatment, the clinical efifcacy of the two groups were compared. Results 1 months after treatment, symptom relief rate in study group was 98.21%, higher than 87.50%in control group, (χ2=4.846, P=0.028);ulcer healing rate in study group was 94.64%, superior than 75%in control group (χ2=8.391, P=0.004);HP eradication rate in study group was 89.29%, higher than 73.21%,in control group (χ2=4.747, P=0.029);adverse medication in the process were nausea, vomiting, loss of appetite, anorexia, dizziness, weakness, abdominal pain and distension, there were no signiifcant differences between two groups. 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.

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.

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 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.

Objective To observe the time-intensity curve characteristics of contrast agents in intraocular tumor.Methods A total of 236 patients (238 eyes) with intraocular tumor were enrolled in this study.All the patients received regular ophthalmologic examination,two dimensional ultrasound,color doppler ultrasonography and contrast-enhanced ultrasonography.There were 166 patients (166 eyes) with choroidal melanoma,16 patients (18 eyes) with choroidal metastatic carcinoma,52 patients (52 eyes) with choroidal hemangioma,two patients (two eyes) with retinal hemangioma.The whole process of contrast-enhanced ultrasound were recorded, and exported as t images of Dicom format.These images were processed by Sonoliver software (Tomteck Company, Germany) to drawn the time-intensity curve of contrast agents in the intraocular tumors.Results All intraocular lesions were completely filled with contrast agent,concentric filling from the periphery to the center can be documented in some cases.The time-intensity curve of choroidal hemangioma and retinal hemangioma were basically the same.The time-intensity curve of choroidal melanoma and choroidal metastatic carcinoma were also basically the same.In the filling phase,all tumors were rapid filling type.In the regression phase,contrast agent subsided earlier than in control tissue within the melanoma or metastatic carcinoma lesions,but subsided synchronous or slightly faster than in control tissue within the choroidal hemangioma and retinal hemangioma lesions.Among 166 eyes with choroidal melanoma,138 eyes (83.1％) were in full compliance with the above changes,28 eyes (16.9％) were largely in line with these changes.All the eyes (100.0％) with choroidal metastatic carcinoma,choroidal hemangioma and retinal hemangioma were in full compliance with the above changes.Conclusion Time-intensity curve is quickly filling and fast regression for malignant intraocular tumors,but is quickly filling and slow regression for benign intraocular tumors.

Objective To discuss the diagnosis characteristics and clinical value of posterior vitreous detachment (PVD) by color Doppler flow imaging(CDFI). Methods One thousand and two cases were examed by CDFI for the diagnosis standard and property of PVD. Results Typical acoustic properties of PVD: the B scan may show a very fluid thick line. There were two types complete PVD and part PVD based on the vitreous separated from the optic nerve. Kinetic echography typically showed a very fluid, undulating after movement of the completely PVD. Part PVD had more than one dot with attachments to the retina and less mobile than complete PVD. There was not blood flow signal on the PVD by CDFI. Conclusions Ultrasonography for PVD not only exactitudes,but also provides foundation for clinic.

Once uveal melanoma (UM) has distant metastasis, the median survival time of the patient is less than 12 months. There is currently a lack of standard treatment for metastatic UM. In recent years, immunotherapy is splendid in the field of oncology. Immune checkpoint therapy, cancer vaccine therapy and T cell adoptive therapy have been applied to UM therapy. However, most of the clinical effects are limited and the survival benefit is not high. The recent early research results of the new immunotherapeutic drug IMCgp100 are encouraging.

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 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 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
