Obesity and its related metabolic diseases have become a major global public health threat, and its rising incidence significantly increases the risk of cardiovascular and cerebrovascular diseases, diabetes and other complications. Pancreatic lipase is a key enzyme that converts food-borne lipids into triglycerides and fatty acids, and the effective inhibition of its activity has become an important strategy for the treatment of obesity. This paper discusses the screening methods of pancreatic lipase inhibitors, and summarizes and reviews the basic principles, advantages and disadvantages and application status of traditional screening methods, modern new screening methods and virtual screening methods. In view of the problems faced by the screening methods of pancreatic lipase inhibitors, future research urgently needs to move towards a collaborative innovation path of multi-technology integration, intelligent screening and complex systematization of traditional Chinese medicine, so as to open up new research paradigms.

Objective To analyze the urban drinking water quality and its influencing factors in Anhui Province from 2014 to 2022, and to provide a scientific basis for water quality improvement and protection. Methods The data were collected, saved and monitored according to the Standard Test Method for Drinking Water (GB/T5750-2006) and evaluated according to the Hygienic Standard for Drinking Water (GB 5749-2006). Results A total of 20 941 samples were collected, and the overall qualified rate was 84.26%. The qualified rate of urban drinking water increased from 76.9% in 2014 to 93.3% in 2022, and the qualified rate of water quality was on the rise (χ²=544.43, P＜0.01). From 2014 to 2022, the qualified rate of water quality in dry season was higher than that in wet season (χ²=35.98, P<0.001), the qualified rate of surface water was higher than that of ground water (χ²=4440.8, P<0.001), and the qualified rate of peripheral tap water was higher than that of factory water (χ²=145.1, P<0.001). Among all kinds of disinfection methods, chlorination disinfection had the highest qualified rate (χ²=1483.8, P<0.001). The qualified rate of water quality increased with the increase of the scale of water plant. Among the inspected indicators, the main unqualified indicators were chlorine dioxide (7.72%), fluoride (7.41%), free residual chlorine (3.90%), and total bacterial count (2.13%). Conclusion The passing rate of urban drinking water quality in Anhui Province is on an upward trend, and the quality of urban drinking water has improved. However, it is still important to pay attention to the problem of excessive microorganism and fluoride in water, and the quality of drinking water varies from place to place.

Objective To observe the clinical efficacy of"three modulation acupuncture"combined with repeated functional magnetic stimulation(rFMS)in the treatment of neurogenic bladder with detrusor muscle weakness after spinal cord injury.Methods A total of 120 patients with neurogenic bladder with detrusor muscle weakness after spinal cord injury were divided into conventional treatment group,"three modulation acupuncture"treatment group,rFMS treatment group and comprehensive treatment group according to the random number table method,with 30 patients per group.The conventional treatment group was given conventional rehabilitation treatment,the"three modulation acupuncture"treatment group was treated with"three modulation acupuncture"(modulating spirit,modulating reflex arc,and modulating lower jiao and waterway)based on conventional rehabilitation treatment,the rFMS treatment group was treated with rFMS based on conventional rehabilitation treatment,and the comprehensive treatment group was treated with"three modulation acupuncture"and rFMS based on conventional rehabilitation treatment.The first desire to void(FDV),maximum cystometric capacity(MCC),maximum detrusor pressure of urine storage period(Pdet.max),maximum intravesical pressure of urine storage period(Pves.max),average daily urination frequency,average daily urine leakage,residual urine volume,and neurogenic bladder symptom scores of the patients were compared before and after treatment,and the clinical effectiveness of each group was evaluated.Results After treatment,the FDV,MCC,and Pdet.max of the four groups were all increased compared with those before treatment,and Pves.max,the average daily urination frequency,the average daily frequency of urine leakage,the residual urine volume,and the neurogenic bladder symptom scores were all decreased(P<0.05).After treatment,the FDV,MCC,and Pdet.max of the"three modulation acupuncture"treatment group,the rFMS treatment group and the comprehensive treatment group were all higher than those of the conventional treatment group,and Pves.max,the average daily urination frequency,the average daily frequency of urine leakage,the residual urine volume,and the neurogenic bladder symptom scores were all lower(P<0.05).After treatment,the comprehensive treatment group had a higher FDV,MCC,and Pdet.max than the"three modulation acupuncture"treatment group and rFMS treatment group,and Pves.max,the average daily urination frequency,the average daily frequency of urine leakage,the residual urine volume,and the neurogenic bladder symptom scores were lower(P<0.05).The curative efficiency rates were 86.2%(25/29)in the"three modulation acupuncture"treatment group,85.7%(24/28)in the rFMS treatment group,and 92.6%(25/27)in the comprehensive treatment group,which was higher than that of the conventional treatment group,which was 75.9%(22/29).Conclusion"Three modulation acupuncture"and rFMS can effectively improve the functional status of the bladder in patients of neurogenic bladder with detrusor muscle weakness after spinal cord injury,and their combined application has a synergistic effect.

Objectives To evaluate the relationship between body mass index (BMI) and the incidence risk of papillary thyroid microcarcinoma (PTMC).Methods This retrospective study included 1210 PTMC patients who underwent surgery between November 2013 and October 2014 in Peking Union Medical College Hospital,China Academy of Medical Science.A population-based 1∶1 matched case-control study was conducted,and each PTMC patients was matched with one who received thyroid function and ultrasonic to confirm that there was no disease in the thyroid.The clinical profiles of these patients were collected.According to Guidelines for Prevention and Control of Overweight and Obesity in Chinese Adults,all subjects were divided into three groups:underweight (BMI ≤ 18.5 kg/m2),normal(18.5 kg/m2 ＜ BMI ≤ 23.9 kg/m2),overweight (24.0 kg/m2 ＜ BMI ＜ 27.9 kg/m2) and obese group(BMI≥28.0 kg/m2).The relationship between BMI and PTMC incidence risk was analyzed by casecontrol study.Univariate and multivariate logistic regression analysis was applied to analyze the relationship between BMI and PTMC severity.Results The BMI of PTMC patients was significant higher than in normal control [(24.30 ±3.33) kg/m2 vs (23.31 ± 3.50) kg/m2,P ＜ 0.0001].Compared with BMI normal group,the incidence risk of PTMC in underweight group was significantly lower (OR =0.449,95 ％ CI:0.270-0.747),which is higher in overweight and obese group (OR =1.559,95％ CI:1.261-1.928;OR =2.059,95％ CI:1.501-2.823).Histopathological review of 1210 PTMC patients with surgical resection revealed.The proportions of underweight,normal,overweight and obese group of the patients with extrathyroid extension (3.1％,48.0％,36.7％,12.2％) have significant differences with those in the patients whose tumor are limited to the thyroid (0.7％,45.2％,36.0％,18.1％) (P =0.0090).The proportions of 4 group of the patients with multiple lesions (3.2％,49.0％,35.6％,12.2％) were significantly differences to those in the patients with single lesion (0.8％,43.3％,38.7％,17.2％) (P =0.0050).Multivariate analysis showed that underweight is a protective factor of extrathyroidal extension (OR =0.219,95 ％ CI:0.051-0.932;OR =0.279,95 ％ CI:0.085-0.935) and mulifocality,and obese is an independent risk factors(OR =1.556,95％CI:1.047-2.312;OR =1.764,95％CI:1.204-2.584).Conclusions This study identified that the incidence risk of PTMC is positive related with BMI.In PTMC patients,obesity increases the risk of mulifocality and extrathyroidal extension.Attention should be paid to the effect of obesity on the incidence risk of PTMC and the diagnosis and treatment in clinical practice.

Objective:To investigate the prognostic significance of high sensitivity-C reactive protein (Hs-CRP) in patients with peripher-al T-cell lymphoma (PTCL). Methods:A total of 234 newly diagnosed PTCL patients with a median age of 48 years were analyzed retro-spectively. Serum Hs-CRP levels and other factors, including tumor stage and international prognostic index (IPI), were determined. Af-ter a median follow-up of 23 months, the relationship between Hs-CRP and overall survival (OS) was observed. Results:Serum Hs-CRP level positively correlated with IPI score (r=0.132, P<0.001), tumor stage (r=0.183, P=0.005), B symptoms (r=0.225, P=0.001), and lactic dehydrogenase (r=0.169, P=0.009), but negatively correlated with plasma albumin levels (r=?0.343, P<0.001), hemoglobin concentra-tion (r=?0.239, P<0.001), and platelet count (r=0.131, P=0.045), and is uncorrelated with age (P>0.05), gender (P>0.05), fitness score (P>0.05), and leukocyte count (P>0.05). Patients with serum Hs-CRP levels≤10 mg/L had better OS than patients with serum Hs-CRP levels>10 mg/L. Univariate and multivariate Cox regression models showed that platelet count, Hs-CRP, albumin levels, and IPI score were independent adverse prognostic factors. Conclusion:The baseline Hs-CRP level can serve as a major indicator of prognosis in PT-CL patients.

Objective: To review the clinical-pathology characteristics of 19 relapsed pediatric mature B cell lymphoma and to find the risk factors for recurrence and the feasible treatment after relapse. Method: Data of 212 pediatric B cell lymphomas cases in Beijing Children′s Hospital from January 2006 to June 2015 were collected retrospectively. All the patients were treated according to the B cell lymphoma regimen of Beijing Children′s Hospital. During the study period, 19 of 212 cases were relapsed; the clinio-pathological characteristics of relapsed patients before treatment and after relapse were analyzed retrospectively, the treatment outcomes after relapse were summarized and the patients were followed-up. Result: Nineteen of 212 cases had relapsed disease, for these relapsed patients: the median age at initial diagnosis was 5.5 years old, the median level of uric acid was 384(range, 121-713)μmol/L, the median level of lactate dehydrogenase(LDH) was 1 323(range, 146-6 370)U/L. Among 19 relapsed patients, 10 had local relapse and 9 had multiple relapses; 17 were Burkitt′s lymphoma and 2 were diffuse large B cell lymphoma. Staging: 2 cases were stageⅡ, 3 cases were stage Ⅲ and 14 cases were stage Ⅳ. Risk group: 6 cases were group B and 13 cases were group C. Nine cases had bone marrow involvement and 10 cases had central nervous system(CNS) involvement. Acute tumor lysis syndrome was seen in 6 cases during the early treatment and 13 cases had delayed treatment. Treatment after relapse: 10 cases received further treatment after relapse (rituximab + 1-4 courses high intensity second-line chemotherapy), 3 cases received autologous stem cell transplantation. There was no chemotherapy or infection related death, 3 cases achieved complete remission (CR). For all the 212 patients, the median follow-up time was 47 (range, 1-131)months and the 5-year event free survival(EFS)rate was (89.4±0.2)%. For the 19 relapse cases, the 5-year overall survival (OS) rate was (21.1±0.1)%, CR rate after relapse was 30%, patients died of the progression of the primary disease, no treatment related death occurred. Univariate analyses showed that bulky disease, stage Ⅳ, maxillofacial and CNS involvement, LDH>1 000 U/L, delay treatment, day 7 evaluation shrink <25%, residual diseases after 3 months treatment are relapse risk factors (all P<0.01). Conclusion Patients relapse during the treatment or at the early stage after the end of all chemotherapy have poor prognosis. So far there is no effective method for early relapse patients; the late relapse patients had the possibility of CR if they are sensitive to salvage treatment. In conclusion, to improve the outcome, the key point is to reduce the relapse.

Objective To investigate the associated risk factors of postoperative complications after rad?ical resecting of colorectal cancer. Methods The clinical data of 237 patients with colorectal cancer performed radical resection in the Second Affiliated Hospital of Kunming Medical University from January 2011 to Decem?ber 2014 were analyzed retrospectively. The incidence of postoperative complications was analyzed,and the relat?ed factors were analyzed by single factor and multi factor correlation analysis. Results The postoperative com?plications occurred in 114 cases of 237 patients( 48. 1%) . Univariate analysis showed that the age more than 70 years old,preoperative comorbidity,intraoperative blood loss,surgeon’ s experience,combined evisceration or en?larged evisceration were related to postoperative complications ( P = 0. 033, 0. 014, 0. 045, 0. 028, 0. 040 ) . Compared with the patients without complications,the postoperative anal exhaust time,length of stay was longer of the patients with complications((3. 7±1. 6) d vs. (3. 2±1. 4) d,P=0. 035;(21. 3±6. 5) d vs. (12. 1 ±2. 4) d,P=0. 001). Logistic regression analysis showed that depth of tumor invasion(P=0. 001),preoperative comorbidity including NRS>3 points (χ2 =8. 903, P=0. 003 ) , anemia and hypoproteinemia (χ2 =3. 494, P=0. 048) ,hypertension complicated with type 2 diabetes mellitus(χ2=5. 418,P=0. 026) ,not complete intesti?nal obstruction(χ2=8. 376,P=0. 003),mild and severe ventilation dysfunction(χ2=6. 331,P=0. 011) and WBC<3. 9×109(χ2=4. 256,P=0. 041) were closely related to the occurrence of complications. The rate of post?operative complication of laparoscopic group and open group had no significant difference( 44. 4%( 64/144) vs. 47. 3%(44/93),P>0. 05) . Conclusion Age>70 years old,preoperative comorbidity,intraoperative blood loss,surgeon`s experience,combined evisceration or enlarged evisceration are main risk factors for patients per?formed colorectal cancer radical resection,but laparoscopy?assisted radical resection is not the risk factor.
