RESUMO
Objective:To explore the efficacy of doctor-nurse co-led care involving education and engagement of patients on improving compliance of patients, and a treat-to-target urate-lowering rate for gout.Methods:Nurses were trained in practice management of gout. Patients diagnosed with gout in the departments of rheumatology and immunology of Anqing Municipal Hospital in Anhui Province were prospectively enrolled from January 1 to June 30, 2019. The patients were divided into the continuous-care group and the conventional management group by random number table method. The patients of continuous-care group received telephone follow-up, WeChat tracking and regular face-to-face communication. The patients of conventional management group were told to follow up regularly in the outpatient department, and the nurses did not follow up. Patients were evaluated before intervention and 12 months after intervention. The treat-to-target rate of blood uric acid and the frequency of gout flares were observed.Results:After 12 months of intervention, the patients of serum uric acid concentrations below 360 μmol/L were 92.39% (85/92) in the continuous-care group, and 26.74% (23/86) in the conventional management group. There was significant difference ( χ2 value was 80.282, P<0.001). After 12 months of intervention, the average serum uric acid concentration of patients in the continuous-care group was (301.6±61.4) μmol/L, and that in the conventional management group was (419.0±98.0) μmol/L, both of which were significantly lower than before intervention, continuous-care group (466.1±119.7) μmol/L, conventional management group (477.8±113.1) μmol/L. But the average serum uric acid concentration of patients in the continuous-care group was significantly lower than that in the conventional management group. There was significant difference between them ( t value was 96.678, P<0.001). At the end of 12 months, the patients of uric-acid-lowering therapy increased in both groups. The proportion of patients was 94.56% (87/92) in the continuous-care group, which was significantly higher than that in the conventional management group (58.14%, 50/86), there was significant difference ( χ2 value was 33.260, P<0.001). Conclusions:The mode of continuing nursing combined with specialized physician-led treatment can significantly improve the compliance and the control rate of treat-to-target for gout, and this management method is simple and feasible which provides a new management concept for clinical treatment of gout.
RESUMO
Objective To investigate the clinical value of penetrating-suture type pancreaticojejunostomy (PPJ) after pancreaticoduodenectomy (PD).Methods The clinical data of 77 patients who received pancreaticoduodenectomy from Taixing People's Hospital from June 2002 to March 2012 were retrospectively analyzed.Of all the patients,34 received PPJ after PD (PPJ group),and the other 43 patients received PJ anastomosis (control group) based on the texture and size of the pancreas,pancreatic duct diameter (duct-to-mucosa pancreaticojejunostomy for pancreatic duct diameter ≥ 4 mm,end-to-end or binding pancreaticojejunostomy for pancreatic duct diameter ≤3 mm).Pancreatic fistula was diagnosed according to the criteria of the International Study Group on Pancreatic Fistula,including grade B or C pancreatic fistula with clinical value.Patients were followed-up through outpatient examination and telephone interview till May 2012.Data were presented by x ± s or median (range) and the t-test and Wilcoxon rank-sum test were used to evaluate quantitative data with or without normal distribution,respectively.Qualitative data were analyzed using Pearson x2 test or Fisher's exact test.Results The mean diameter of the pancreatic duct was 3 mm for both the PPJ group and the control group.The external drainage via the pancreatic duct stent was not used in the PPJ group,compared with 4 cases in the control group,showing a statistically significant difference between the 2 groups (x2=3.632,P ＜ 0.05).The duration of pancreaticojejunostomy was 12 minutes (range,8-25 minutes) in the PPJ group,while no records in the control group.The operation time and intraoperative blood loss in the PPJ group and the control group were (304 ± 60)minutes and (475 ± 75) mL,(304 ± 60) minutes and (500 ± 97) mL,respectively.Twenty-four (70.6％) patients in the PPJ group and 29 (67.4％) patients in the control group received intraoperative blood transfusion,with volume of 400 mL (range,300-800 mL) and 600 mL (range,300-1 200 mL),respectively.The median duration of postoperative hospital stay were 18 days (range,11-32 days) in the PPJ group and 20 days (range,9-44 days) in the control group.None of these comparisons were statistically significant between the 2 groups (t =1.293,0.619,x2=0.088,Z =0.165,0.074,P ＞0.05).The rate of grade B or C pancreatic fistula were 0 for the PPJ group and 27.9％ (12/43) for the control group,and the mortality rate of patients who had pancreatic fistula were 0 and 11.6％ (5/43) for the PPJ group and the control group,with statistical significance (x2=11.232,4.237,P ＜0.05).The overall incidence of bile leakage,peritoneal bleeding and delayed gastric emptying in the PPJ group and the control group were 5.9％ (2/34),2.9％ (1/34),5.9％ (2/34) and 11.6％ (5/43),7.0％ (3/43),14.0％ (6/43),with no significance difference (P ＞0.05).Fifty-six patients were followed up after operation from 9 months to 5 years.Pancreatic duct dilation was detected by imaging examination for 26 patients in the control group.Conclusions PPJ is a simple and feasible approach with better clinical efficacy after PD.

Objective To investigate the features,diagnosis and treatment of plasma cell mastitis,looked forward to improving the awareness of plasma cell mastitis and raising the cure rate.Methods Retrospectively analysized the clinical data of 43 patients suffering from plasma cell mastitis from March 2000 to January 2013,to summarize the methods of diagnosis and treatment.Results All forty-three patients were treated by surgery.Thirty-nine patients were undergone partial resection of breast.Four patients recurred after simple incision and drainage having been misdiagnosed breast abscess initially.Then the four patients adopted partial resection of breast.All forty-three patients were postoperative followuped from 9 months to 3 years,three cases with reoperation of recurrence were no relapse again.Conclusions The clinical feature of plasma cell mastitis is sophisticated with misdiagnosis and mistreatment.The final diagnosis depends on pathological examination.Operation is the effective method to cure the disease.It is very important to select the correct timing of surgery and the operative method for plasma cell mastitis.
RESUMO
Objective To estimate the efficacy and safety of 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) in the treatment of lichen sclerosus et atrophicus of the vulva.Methods An open and noncontrolled clinical study was performed.Forty-two patients were enrolled in this study and received ALA-PDT once every two weeks for 2 to 4 times.Follow-up visits were arranged at 2,4 and 8 weeks after initiation of treatment,and patients were evaluated at the baseline (before treatment) and all the follow-up time points for the efficacy and safety of treatment.Results Finally,38 patients completed the trial and 4 patients were lost to follow up.The total response rate was 81.6％ (31/38) at the end of the treatment.The average symptom and sign score in these patients was significantly lower at 2,4 and 8 weeks after initiation of treatment than that before treatment (17.6 ± 10.18,11.6 ± 8.35 and 7.6 ± 5.93 vs.29.3 ± 9.17,t =5.26,8.80,12.22,respectively,all P ＜ 0.01).A significant improvement was also observed in the other aspects,such as skin lesion area,hypopigmentation,erosion/rhagades and itching score at 2,4 and 8 weeks,as well as in skin atrophy at 8 weeks after initiation of treatment compared with those before treatment (all P ＜ 0.05).Local burning sensation was the main adverse reaction to ALA-PDT,and 16％ (6/38) of these patients complained of severe pain during the first treatment.Conclusion ALA-PDT shows favorable efficacy in patients with lichen sclerosus et atrophicus of the vulva with a rapid onset of action.
RESUMO
Objective To establish a porcine model of penetrating-suture pancreaticojejunostomy.Methods Ten domestic pigs were selected,and after general anesthesia they underwent laparotomy and the pancreas was visualized.Then the pancreas was dissected at the level of superior mesenteric vascular,and the proximal pancreatic stump was sewed up.The anastomosis between the distal pancreatic stump and the intestinal wall adopted penetrating-suture pancreaticojejunostomy; the digestive tract was reconstructed by Roux-en-Y.Results The anastomosis with penetrating-suture pancreaticojejunostomy was successful in ten domestic pigs.The mean pancreatic stump diameter was 2.5 cm,and the mean pancreatic duct diameter was 1.5 mm,the mean time for operation was 1.0 ～ 2.5 h,and the average time of pancreaticojejunostomy was 8 minutes.The mean blood loss was 25 ml.After operation,diarrhea occurred in 2 pigs and wound infection occurred in 1 pig,and all were cured with appropriate management.No pig died intra-operatively,and no pancreatic fistula or death occurred after operation.Conclusions A porcine model of penetrating-suture pancreaticojejunostomy is successfully established.

RESUMO
Objective To investigate the inhibitory effects of RNA interference on expression of matrix metalloproteinase-2(MMP-2)gene and invasiveness of human pancreatic cancer cell line PANC-1 in vitro.Methods Small interference RNA targeting MMP-2 gene was designed and constructed to plasmid pGCsi-U6.Recombinant plasmids were transfected to pancreatic carcinoma PANC1 cells with Lipofectamine 2000.The efficiency of transfection was evaluated by flow cytometry.RQPCR was used to detect the expression of MMP-2 mRNA.The expression of MMP-2 protein was determined by ELISA.The invasiveness of PANC-1 cells was measured by transwell chamber experiment.MTT assay was used to detect the proliferation and growth of PANC-1 cells.Results Sequencing confirmed that the MMP-2 siRNA plasmid was successfully constructed.The best efficiency of transfecting recombinant plasmid was 82.1%.After transfection of the MMP-2 siRNA plasmid, the MMP-2 gene expression of PANC-1 cells was suppressed to 71.74 %(P＜0.05),and protein expression of MMP-2 fell to 49.82%(P＜0.05).The corresponding inhibition ratio of invasiveness was 33.0%(P＜0.05).There was no marked difference in proliferation rate measured by MTT assay among different groups(P＞0.05).Conclusions RNAi targeting MMP-2 can suppress invasiveness of PANC-1 cells in vitro.This suggests that MMP-2 could be a target for gene therapy of pancreatic carcinoma.RNAi is expected to open up a new prospect for tumor therapy.
RESUMO
Objective To analyze the correlation of metabolic syndrome (MS) and its components with a future development of diabetes mellitus (DM) in elderly patients. Methods In 2007, the cohort study was carried out among the 2001 baseline population. The criteria which was proposed by international diabetes federation in 2005 was referred to diagnose MS. Results MS predicted the future development of DM (RR = 4. 70, 95% CI:3.23～6.85). Among MS components, fasting glucose exhibited the highest association with DM. The univariate analysis showed that while fasting glucose was more than 5. 6 mmol/L, the RR(95% CD was 9. 68(6. 59～ 14.23). And multiple factors analysis showed that while fasting glucose was 5.60 mmol/L～6. 09 mmol/L, the RR(95% CD was 5. 49(3. 38～8. 92). While glucose level was more than 6. 1 but less than 7.0 mmol/L, the RR(95% CI) increased to 14.44(9.29～22.44). However, along with the increasing of cluster number of MS components from 1,2,3,4 to 5, the corresponding RR increased from 2. 92, 5. 67, 12. 28, 19. 52 to 37. 83. Conclusions MS increases the risk of DM. Among MS components, fasting glucose level is the strongest risk indicator of DM.
RESUMO
Objective To study the effect of PUMA gene mediated by recombinant adenovirus vector combined with radiation on the pancreatic carcinoma. Methods The PANC-1 cells were infected with Ad-PUMA (MOI = 10, 50 and 100, respectively) for 48 h. The expression of PUMA mRNA and protein was detected by RT-PCR and Western blot, respectively. PANC-1 cells were divided into 4 groups: control group, transfection group, irradiation group and combined treatment group. The cell growth inhibition rate and apoptotic rate of PANC-1 cells were assessed by MTT assay and flow cytometry. Human pancreatic carcinomas were transplanted subcutaneously in nude mice, which were randomized into 4 groups: control group, transfection group, irradiation group and combined treatment group. Tumor growth rate and apoptotie index at different time points were recorded in 35 days. Results The expression of PUMA mRNA and protein was increased with the increase of MOI of Ad-PUMA, which was does-dependant (MOI = 10, mRNA = 0.46 ± 0.02, protein = 0. 75 ±0.09;MOI=50, mRNA= 1.12±0.09, protein = 1.01 ±0.18;MOI= 100, mRNA= 1.50±0.08, protein=1.80 ± 0.15 ;P < 0.05). The proliferation of PANC-1 cells was suppressed significantly when transfected by Ad-PUMA in a dose-dependent manner(r = -0.986 55), which was more significant combined with radiation (r = -0.971 26, P < 0.05). Meanwhile, the apoptotie rate was increased in the same manner [for pre- and post-irradiation,which was (45.4 ± 5.26) % and (73.2 ± 6.62) %, respectively, P < 0.05]. From 7 to 35 d after PUMA gene transfection and radiotherapy, the tumor growth was significantly slower than those of irradiation group, transfection group and control group [35 d after therapy, the volume of tumor was (19.82 ± 6.45)mm3 ,(39.5 ± 9.23)mm3 , (33.6 ±3 10.3)mm3 and (52.0 ± 11.43)mm3 , respectively, P < 0.05]. And the apoptotic index was increased in the same manner (AI = 0.43 ± 0.05, 0.29 ± 0.10, 0.24 ± 0.05 and 0.00 ± 0.00, respectively, P < 0.05). Conclusions Recombinant adenoviral-mediated PUMA gene combined with irradiation could increase the cell-killing effect on pancreatic carcinoma. It is better than that of either one kind of therapy.
RESUMO
Objective To investigate the expression of matrix metalloproteinase-2 (MMP-2)in pancreatic carcinoma and the relationship between MMP-2 with tumour clinicopatholngical features. Methods The expression of MMP-2 was detected by S-P immunohistochemistry in 36 cases with pancreatic carcinoma and 14 normal pancreat-ic tissues. Results The positive expression rate of MMP-2 was 66.7% (24/36) in pancreatic carcinoma tissue and 14.3% (2/14) in normal pancreatic tissues (χ2 = 3. 587, P < 0.01 ) ;The expression rate of MMP-2 in pancreatic carcinoma tissue with positive-node was 86.7% ( 13/15 ) ,which was higher than that with negative-node,which was 52.4% ( 11/21 ) ( P < 0.05 ) ; As to TNM staging in pancreatic carcinoma, the expression rate of MMP-2 was 41.2% (7/17) with Ⅰ,Ⅱ staging and 89.5% (17/19) with Ⅲ,Ⅳ staging(χ2=9.418,P <0. 01 ) ;The expression rate of MMP-2 was 50.0% (5/10) ,66.7% (10/15) and 72.8% (8/11) in highly,moderately and poorly differentiated pancreatic carcinoma(P > 0.05 ). Conclusions The expression of MMP-2 is strengthened significantly in pancreatic carcinoma tissue and involved in turnout invasion and metastasis features; MMP-2 might be regarded as one more marker for the invasive properties of pancreatic carcinoma.
RESUMO
BACKGROUND: The cluster of multiple metabolic disorders, namely raised blood pressure, overweight or obesity, raised triglyceride level, reduced high density lipoprotein cholesterol (HDL-C) level were the predictor of type 2 diabetes mellitus (DM). However, similar data especially the old people's data is relatively rare in China.OBJECTIVE: To analyze the relationship between the components of metabolic syndrome (MetS), their clusters and the risk of diabetes among Chinese old population.DESIGN: Cross-sectional study.SETTING :Beijing Institute of Geriatrics, Beijing Hospital, Ministry of Public Health.PARTICIPANTS: The study was carried out from February 2001 until November 2001.4 499 volunteers aged 60 and over were recruited from the academic institutes in Beijing Xicheng, Haidian and Shijingshan districts through cluster sampling methods. They were selected after excluding those who did not have integral data.METHODS: Diabetes was considered when fasting glucose was ≥7.0 mmol/L and was treated for or diagnosed as DM. Chi-square tests were performed to compare the categorical data. Age and sex adjustment were taken in the comparison of the levels of blood pressure, waist circumference (WC), The body mass index (BMI), and lab variables, Multifactor stepwise (backward)Logistic regression analyses were used to select the factors which would have association with the risk of DM. When analyzing the relationship between number of clustering of the traits of MetS and DM, the group without any metabolic abnormalities was set as control group. The dummy variables were set for 1,2,3,4 clusters of metabolic abnormalities. The Logistic regression model was used again to test the relationship and adjusted by age and the family history of DM.MAIN OUTCOME MEASURES: The blood glucose, waist, BMI, blood pressure, triglyceride (TG), HDL-C, and family history of diabetes of subjects.RESULTS: 4 444 people in the mean age of 65±5 were retrieved. 556cases of DM were found in this survey. Age, family history of diabetes,systolic blood pressure, waist and TG were independently associated with the risk of DM, with OR (95%CI) being 1.02 (1.00-1.04), 3.48(2.76-4.39), 1.02 (1.01-1.02), 1.03 (1.00-1.03), 1.13 (1.05-1.21), respectively. When TG was not in the model, HDL-C was also inversely associated with DM (OR=0.67, 95%CI 0.49-0.91). The risk of DM increased with clustering of abdominal obesity, raised blood pressure, raised TG, and reduced HDL-C level in individuals.CONCLUSION: In addition to age and genetic factors, metabolic factors, especially their clusters are closely related to the risk of diabetes. Therefore, the features of MetS are important indicators for the risk of DM in aged people.
