A total of 267 patients with pressure ulcer were randomly divided into treatment and control groups.All of them underwent traditional debridement.The wounds in treatment group were spreaded with traditional Chinese medicine.According to the results of bacteria culture and drug sensitivity,antimicrobial agents were selected in control group.The observation indices of two groups included pain grade,swelling grade,ulcer area and skin temperature difference.Then the variations of observation indices before and after treatment were examined.In treatment and control groups,the different values of pain grade before and after treatment were 2.1 ± 0.9 and 1.2 ± 0.7,swelling grade 1.3 ± 0.6 and 0.7 ± 0.5,ulcer area 4.7 ± 3.1 and 2.4 ± 2.5 and skin temperature difference 0.12 ± 0.05 and 0.22 ± 0.10 respectively.Treatment group was superior to control group and there was statistical significance (P ＜ 0.05).The effective rates were 95.6％ and 65.4％ and the number of cured patients 86 and 33 cases respectively.And there was statistical significance (P ＜ 0.05).

AIM: To observe the effect of intraocular lens ( IOL) implantation on visual acuity and contrast sensitivity in patients with cataract.
METHODS: Fifty - eight cases ( 72 eyes ) cataract patients with regular cornel astigmatism, in our hospital from May 2014 to May 2015 were randomly divided into two groups to undergo phacoemulsification and IOL implantation: the observation group: 29 cases (36 eyes) received multifocal toric IOL implantation; the control group: 29 cases (36 eyes) received monofocal toric IOL implantation. Uncorrected distance visual acuity ( UCDVA), uncorrected near visual acuity ( UCNVA), best corrected distance visual acuity (BCDVA), the best corrected near visual acuity ( BCNVA ), total eye astigmatism, and the dark contrast sensitivity were observed for these patients at 1 and 6mo after cataract surgery.
RESULTS: There were no statistical significant difference between the two groups at postoperative 1, 6mo on UCDVA, BCNVA, BCDVA and total eye astigmatism(P>0. 05). UCNVA of observation group at 1 and 6mo were better than those of control group ( P <0. 05); there were statistically significant difference in high frequency comparison at the sixth postoperative months (P<0. 05).
CONCLUSION: Both monofocal toric IOL implantation, and aspheric multifocal toric IOL implantation for cataract with regular corneal astigmatism are effective to improve visual acuity. But the latter treatment would contribute to the improvement of uncorrected near visual acuity and the dark contrast sensitivity.

In recent years the interaction between host and gut microbiota has attracted increasing attention. However, intestinal flora dysbiosis may lead to many diseases, and there is increasing evidence that the intestinal microbiota in patients with chronic kidney disease (CKD) is associated with the pathophysiological status of the host. "Gut-kidney axis" provides a better explanation of the two-way communication between intestinal flora and CKD. Impaired kidney function leads to dysbiosis of intestinal flora and an altered intestinal flora can damage the intestinal mucosal barrier and facilitate the entry into the bloodstream of harmful bacteria, which can induce chronic inflammation and thus accelerate renal injury. In addition, the accumulation of nephrotoxic metabolites from an altered intestinal flora can aggravate CKD in the "gut-kidney axis". Among them, p-cresol sulfate, indoxyl sulfate and trimethylamine oxide are the most widely studied metabolites of nephrotoxicity, and their renal toxicity has been widely confirmed in basic research and clinical studies. Current studies show that the intestinal microbiota-metabolite network is closely related to the occurrence and development of chronic kidney disease. Thus, intervention in the intestinal microbiota may provide a new approach to the prevention and treatment of chronic kidney disease.

Objective To evaluate the association between interleukin-I(IL-1)loci polymorphisms and increased risk of gastric carcinoma in samples from northern Chinese population.Methods Blood sam- ples from 126 patients with gastric cancer and 125 controls with chronic gastritis were collected.Genomic DNA was extracted and polymorphisms at -31(C to T),-511(C to T)and at intron 2(86-bp VNTR)of IL-I RN were genotyped by PCR-CTPP,PCR-RFLP and PCR.For detection of Hp infection fast urenase test,~(14)C breath test and serum anti-Hp IgG antibody assay were used.Results Five kinds of polymorphism of IL-IRN were found as 1/1,1/3,1/4,1/2 and 2/2,and the frequencies in patients were 76.19%、4.76%、6.35%、11.90% and 0.79%,respectively.However,the frequencies in controls were 76.00%、4.00%、4.80%、13.60% and 1.60%.No significant differences were observed between cases and controls in each genotype.The polymorphism of IL-IB-31 allele was C/C,C/T and T/T.The frequencies in patients were 12.70% ,47.62% and 39.68%,and in controls 28.00%,48.80% and 23.20% respectively.IL-1B- 31 T/T carriers were at an increase risk of gastric cancer with an odds ratio of 3.772(95% CI,1.786- 7.966).IL-IB-511 alleles were C/C,C/T and T/T.The frequencies in patients were 19.20%,56.80% and 24.00% and in controls,23.38%,49.19% and 27.42% respectively.No significant differences were observed between cases and controls in each genotype.Conclusion In Chinese population,the polymor- phism of IL-1B-31 alleles may be associated with the susceptibility of gastric cancer.However,no evidence was found to support that the polymorphisms of IL-1RN and IL-I B-511 alleles had relationship with gastric cancer.

OBJECTIVE: To discuss the efficacy and safety of simultaneous bilateral endoscopic surgery (SBES) for bilateral upper urinary tract calculi, and to summarize the initial experience. METHODS: Patients diagnosed with bilateral upper urinary tract calculi who underwent SBES in the Department of Urology, Beijing Chao-Yang Hospital from January 2019 to January 2020 were enrolled retrospectively. The demographic and clinical data of the patients were recorded, and the operation status, stone free rate (SFR) and peri-operative complications were analyzed. The primary end point was SFR, and second end point was peri-operative complications. RESULTS: A total of 23 patients underwent SBES, of which SBES was completed in 19 patients (12 males, and 7 females). The mean age was (41.3±12.0) years. Fourteen patients underwent modified supine position surgery and 4 patients in prone split-leg position. There was no statistical difference in the demographic and baseline clinical data of the patients in different positions. One patient underwent right percutaneous nephrolithotomy (PCNL) and left endoscopic combined intra-renal surgery (ECIRS) in the prone split-leg position, while 18 patients received simul-taneous surgery with PCNL and contralateral retrograde intra-renal surgery (RIRS). The mean anesthesia and operation time was (128.7±26.5) min and (70.7±20.3) min, respectively, which was significantly longer in the patients with prone split-leg position than in the patients with modified supine position, anesthesia time in the patients with prone split-leg position and modified supine position: (148.4±20.4) min vs. (121.6±25.3) min, respectively, t=－2.121, P=0.049, while the operation time in the patients with prone split-leg position and modified supine position: (86.4±21.1) min vs. (65.1±17.4) min, respectively, t=－2.222, P=0.040. There was no significant difference between the two groups in indwelling of nephrostomy [prone split-leg position and modified supine position: (2.6±0.9) d vs. (2.1±1.0) d, respectively; t=－0.880, P=0.391] and the length of hospital stay [prone split-leg position and modified supine position: (6.0±2.7) d vs. (5.2±1.8) d, respectively; t=－0.731, P=0.475]. One month after the operation, the SFR was 78.9%, and 3 patients had minor peri-operative complications (Clavien-Dindo grades Ⅰ/Ⅱ) without any serious complications (Clavien-Dindo grades Ⅲ/Ⅳ/Ⅴ). CONCLUSION The simultaneous bilateral endoscopic surgery would decrease the operation time and anesthesia exposure under the premise of ensuring the SFR, which is helpful to reduce the risk of peri-operative complications, especially to the patients who can not tolerate the second-stage or long-time operation.

Objective To evaluate the value of diffusion-weighted imaging(DWI)on differential diagnosis of intracranial cystic lesions.Methods Seventy-six patients with surgically and pathologically confirmed intracranial cystic lesions undergone conventional MRI,DWI and contrast enhanced MRI examination.The signal characteristics of intracrania]cystic lesions on DWI were analysed retrospectively, the apparent diffusion coefficient(ADC)values of cystic areas were measured quantitatively.Results Nineteen brain abscesses showed hyperintense signal on DWI.Among 34 brain tumors,3 brain gliomas were hyperintense signal,1 brain glioma was isointense signal and 1 metastasis was hyperintense signal;the other 29 brain tumors showed hypointense signal on DWI.The ADC values of all lesions were:(0.62?0.15)? 10~(-3)mm~2/s in brain abscesses,(2.39?0.78)?10~(-3)mm~2/s in brain gliomas,(2.68?0.40)? 10~(-3)mm~2/s in brain hemangioblastomas,(2.79?0.79)?10~(-3)mm~2/s in brain metastases,respectively. There were significant differences between the ADC values of brain abscess and the cystic or necrotic portions of brain glioma,hemangioblastoma,metastasis(P0.05). Seven intracranial arachnoid cysts showed hypointense signal and 16 epidermoid cysts strikingly hyperintense signal on DWI.The ADC values of arachnoid cysts and epidermoid cysts were(2.96?0.36)?10~(-3)mm~2/s and(0.94?0.13)?10~(-3)mm~2/s respectively.There was significant difference between the ADC values of arachnoid cysts and epidermoid cysts(P

Objective To explore the potential mechanism of adrenal androgen excess in patients with polycystic ovary syndrome (PCOS), ACTH stimulation test was conducted and the polymorphisms in the promoter region of CYP21 A2 gene were screened to verify the variations related to the responsiveness to ACTH stimulation. Methods 30 healthy women and 101 PCOS patients, matched for age, were recruited from Ruijin hospital. Blood biochemical examinations were taken and sex hormone profiles obtained at baseline. 17 hydroxyprogesterone( 17OHP)was measured at 0 and 60 min in an ACTH stimulation test. The -710 bp -1 bp of the promoter region of CYP21A2 was sequenced in 87 PCOS patients and 30 control subjects. Results According to the post-stimulation 17 OHP levels obtained from 30 healthy women,PCOS patients were allocated into one group with high responsiveness to ACTH ( HR-PCOS, n = 21) and the other with normal responsiveness to ACTH ( NR-PCOS, n = 80). Compared with NR-PCOS subjects, HR-PCOS patients had higher testosterone( P<0.05), basal and post-stimulation 17OHP (both P<0.01)and dehydroepiandrosterone sulfate levels (P<0.05 or P<0.01) .whereas serum cortisol and androstenedione levels were not significantly different before and after ACTH stimulation test. The genotypes of locus -535 were well correlated with post-stimulation 17OHP levels (r = 0. 20,P = 0. 03) in PCOS patients and the control subjects. The genotype T/T or allele T was significantly more frequent in subjects with a higher fertile of post-stimulation 17OHP (P<0.05 or P<0. 01). The odds ratio(OR)for higher responsiveness to ACTH in women with allele T at -535 was 3. 69 (95% CI 1. 69-8. 06,P = 0. 000 7). Conclusions The PCOS patients with higher responsiveness to ACTH are characterized by severe hyperandrogenemia and adrenal androgenexcess,suggesting that adrenal androgen excess in some PCOS patients may be due to higher responsiveness to ACTH. The polymorphism of -535C>T in the promoter region of CYP21 A2 may play a role in regulating 21 hydroxylase gene expression and further influencing 17OHP responsiveness to ACTH.
