Objective:To investigate the effect of atorvastatin on the blood lipid and uric acid levels of elderly patients with coronary heart disease complicated with diabetes mellitus.Methods:116 patients with coronary heart disease and diabetes were randomly divided into the control group and the experimental group,58 cases in each group.Both groups of patients were given blood glucose control,blood pressure and other symptomatic treatment.The control group was treated with Aspirin Enteric-coated Tablets 0.3～0.6 g/times,3 times/d,oral,clopidogrel tablets,2 tablets each time,1 time/d,oral,nitroglycerin,0.25～0.5 g/time,3 times/d,with service;the experimental group was given atorvastatin on the basis of control group,10～20 mg/time,1 time/d,treatment for 4 weeks.During the treatment,the dosage was timely adjusted according to the conditions of patients.The serum low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C),triglyceride (TG),total cholesterol (TC),uric acid (UA),glycosylated hemoglobin (HbA1c) levels before and after treatment and the clinical treatment efficiency were observed and compared between two groups.Results:Compared with before treatment,the serum LDL-C,TG,TC,UA,HbA1c levels were decreased ahter treatment in both groups of patients,the HDL-C level was increased (P＜0.05);compared with the control group,the serum LDL-C,TG,TC,UA,HbA1c levels were lower,HDL-C level was higher in the experimental group (P＜0.05);compared with the control group,the effective rate of clinical treatment of the experimental group were higher (P＜0.05).Conclusion:Atorvastatin could effectively reduce the blood glucose,blood lipid,uric acid levels of elderly patients with coronary heart disease complicated with diabetes.

Objective To analyze and compare the clinical characteristics of primary sclerosing cholangitis (PSC) with IgG4-related sclerosing cholangitis (IgG4-SC).Methods The clinical data of 32 PSC patients and 72 IgG4-SC patients who were hospitalized in Peking Union Medical College Hospital (PUMCH) from January 2004 to December 2014 were retrospectively analyzed.Results Of the 32 PSC patients,there were 16 male and 16 female.Of the 72 IgG4-SC patients,there were 61 male and 11 female,(ratio =5.5∶ 1).The average ages were 44.9 (11 ～ 77) and 59.8 (28 ～ 83) years,respectively (P ＜0.05).The most common symptoms of PSC and IgG4-SC were abdominal pain and jaundice,and the incidences of abdominal pain and jaundice were 50.0％ and 68.1％,78.1％ and 81.9％,respectively.The serum IgG4 level of the IgG4-SC patients was significantly higher than the PSC patients (P ＜ 0.05).The total protein in serum of the IgG4-SC patients was higher than the PSC patients (P ＜ 0.05).The rate of bile duct wall thickening as detected on endoscopic ultrasonography (EUS) was higher than by abdominal ultrasound and abdominal CT,which were 91.2％,11.5％ and 33.3％,respectively (P ＜0.05).12 PSC patients were followed up for over 2 years,including 2 patients who underwent liver transplantation after failure of conservative treatment,5 patients who died from hepatic failure and infection,and 3 with stable condition.43 IgG4-SC patients were followed up for over 2 years,including 16 patients with relapse.The recurrence rate was 37.2％ (16/43).The more the extrabiliary organs or bile duct segments were involved,the higher was the recurrence rate.Conclusions Both PSC and IgG4-SC are cholestatic diseases,and they have many similarities in clinical and imaging manifestations.However,they still have unique features.IgG4-SC is sensitive to glucocorticoids therapy and has good prognosis.Thus,it is important to differentiate PSC from IgG4-SC.

Objective:To investigate the influencing factors for the number of lymph node harvested after Da Vinci robotic and laparoscopic radical gastrectomy for gastric cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 1 396 patients who underwent Da Vinci robotic or laparoscopic radical gastrectomy for gastric cancer in the First Affiliated Hospital of Nanchang University from December 2014 to July 2019 were collected. There were 991 males and 405 females, aged (60±11) years. Surgery using Da Vinci robotic system or laparoscopic system was completed according to patients' wishes. Cases with early gastric cancer underwent D 1+ lymphadenectomy and cases with advanced gastric cancer underwent standard D 2 lymphadenectomy. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) influencing factors for the number of lymph node harvested after radical gastrectomy for gastric cancer; (4) follow-up and survival. Follow-up using outpatient examination or telephone interview was performed to detect survival of patients up to October 2020. Measurement data with normal distribution were represented as Mean± SD. Univariate analysis was done using the chi-square test or Fisher exact probability. Multivariate analysis was performed using Logistic regression model. The survival rate was calculated by Kaplan-Meier method. Results:(1) Intraoperative situations: all the 1 396 patients underwent radical gastrectomy, including 415 cases undergoing Da Vinci robotic radical gastrectomy and 981 cases undergoing laparoscopic radical gastrectomy. Thirty-five of the 1 396 patients were converted to open surgery, including 5 cases undergoing Da Vinci robotic radical gastrectomy and 30 cases undergoing laparoscopic radical gastrectomy. Of the 1 396 patients, 983 cases underwent distal gastrectomy, 400 cases underwent total gastrectomy and 13 cases underwent proximal gastrectomy, among which 597 cases underwent Billroth Ⅰ anastomosis, 385 cases underwent Billroth Ⅱ anastomosis, 401 cases underwent Roux-en-Y anastomosis and 13 cases underwent residual stomach-esophagus anastomosis. The operation time, volume of intraoperative blood loss and cases with intraoperative blood transfusion were (221±51)minutes, (201±81)mL, 24 of 415 cases undergoing Da Vinci robotic radical gastrectomy, and (196±42)minutes, (232±76)mL, 75 of 981 cases undergoing laparoscopic radical gastrectomy, respectively. (2) Postoperative situations: the time to postoperative first flatus, time to postoperative initial liquid food intake and duration of postoperative hospital stay of the 1 396 patients were (3.0±1.0) days, (4.2±1.5) days and (9.0±3.8) days, respectively. Two hundred and ten of the 1 396 patients had postoperative complications including 170 cases with grade Ⅰ-Ⅱ complications and 40 cases with grade Ⅲ-Ⅴ complications. Eight of the 210 patients with postoperative complications died of serious complica-tions and the other 202 cases were cured after symptomatic treatment. Results of postoperative histopathological examination showed that there were 958 cases of adenocarcinoma, 220 cases of mucinous adenocarcinoma, and 218 cases of signet ring cell carcinoma. The number of lymph node harvested and the number of positive lymph node of the 1 396 patients were 26.0±8.3 and 3.6±0.9, respectively, and cases with the number of lymph node harvested ≥16 or <16 were 1 312 and 84. (3) Influencing factors for the number of lymph node harvested after radical gastrectomy for gastric cancer: results of univariate analysis showed that the operating surgeon, operation method, range of gastric resection, nerve invasion, degree of tumor invasion and tumor pathological N stage were related factors influencing the number of lymph node harvested after Da Vinci robotic and laparoscopic radical gastrectomy for gastric cancer ( χ2=13.167, 6.029, 15.686, 5.573, 9.402, 17.139, P<0.05). Results of multivariate analysis showed that the operating surgeon, operation method, range of gastric resection and tumor pathological N stage were independent factors influencing the number of lymph node harvested after Da Vinci robotic and laparoscopic radical gastrectomy for gastric cancer ( odds ratio=1.589, 2.018, 1.787, 0.267, 95% confidence interval as 1.221?2.068, 1.140?3.570, 1.066?2.994, 0.103?0.689, P<0.05). (4) Follow-up and survival: of the 1 396 patients, 1 256 cases were followed up for 2 to 70 months, with a median follow-up time of 27 months. The 3-year cumulative survival rate of the 1 256 cases was 70.2%. Conclusion:The operating surgeon, operation method, range of gastric resection and tumor pathological N stage are independent factors influencing the number of lymph node harvested after Da Vinci robotic and laparoscopic radical gastrectomy for gastric cancer.

Objective:To investigate the application value of white noise therapy on the alleviation of procedural pain of colostomy newborns.Methods:By a prospective, randomized and controlled trial, a total of 88 colostomy newborns in Hunan Children′s Hospital from January 2018 to January 2020 divided into experimental group (44 cases) and control group (44 cases) according to the random number table method. The control group received routine nursing; based on thesis, the experimental group played white noise intervention therapy on the basis of routine nursing.

Objective To investigate the clinical efficacy of Da Vinci robotic and laparoscopic distal gastrectomy for gastric cancer.Methods The propensity score matching and retrospective cohort study was conducted.The clinicopathological data of 171 patients with gastric cancer who were admitted to the First Affiliated Hospital of Nanchang University from January 2015 to October 2016 were collected.There were 110 males and 61 females,aged from 38 to 81 years,with a median age of 57 years.Of 171 patients,70 undergoing Da Vinci robotic distal gastrectomy for gastric cancer and 101 undergoing laparoscopic distal gastrectomy were allocated into the robotic group and laparoscopic group,respectively.Observation indicators:(1) the propensity score matching conditions and comparison of general data between the two groups after the propensity score matching;(2) intraoperative and postoperative situations;(3) situations of pathological examination;(4) follow-up.Patients were followed up by outpatient examination and telephone interview to detect severe complications and survival after discharge up to October 2018.The overall survival time was from the operation data to end of follow-up or time of death.The propensity score matching was used to perform 1 ∶ 1 matching by Empower Stats.Measurement data with normal distribution were represented as Mean ± SD,and comparison between groups was done using the t test.Measurement data with skewed distribution were represented as M (range),and comparison between groups was done using the Mann-Whitney U test.Count data were represented as absolute number,and comparison between groups was analyzed using the chi-square test and comparison of ordinal data between groups was analyzed using the Mann-Whitney U test.The survival rate and curve were respectively calculated and drawn by the Kaplan-Meier method,and Log-rank test was used for survival analysis.Results (1) The propensity score matching conditions and comparison of general data between the two groups after the propensity score matching:124 of 171 patients had successful matching,including 62 in each group.The body mass index (BMI) and tumor diameter before matching were (24.2±2.4)kg/m2 and (50±13)mm in the robotic group,(25.1±2.1) kg/m2 and (45±14) mm in the laparoscopic group,showing statistically significant differences between the two groups (t =-2.676,2.045,P＜ 0.05).The BMI and tumor diameter after matching were (24.5 ± 2.3) kg/m2 and (49 ± 14) mm in the robotic group,(24.4 ± 2.2) kg/m2 and (48 ± 12) mm in the laparoscopic group,showing no statistically significant difference between the two groups (t=0.110,0.524,P＞0.05).(2) Intraoperative and postoperative situations:the total operation time,volume of intraoperative blood loss,level of C-reactive protein at day 1 postoperatively,level of C-reactive protein at day 3 postoperatively,volume of totally abdominal drainage were (147±13) minutes,(115±12)mL,(52.2±7.2)mg/L,(33.7±11.9)mg/L,353.5 mL (range,267.0-1 350.0 mL) in the robotic group,and (140± 12) minutes,(131 ± 12) mL,(58.2±7.4) mg/L,(41.1 ± 16.9) rag/L,397.0 mL (range,255.0-1 600.0 mL) in the laparoscopic group,respectively,showing statistically significant differences in the above indexes between the two groups (t =3.163,-7.814,-4.631,-2.840,Z =-4.351,P＜0.05).(3) Situations of pathological examination:patients after matching in the two groups received R0 resection,with negative duodenal margin and gastric margin.The number of lymph nodes dissected in the robotic group and laparoscopic group were 22±4 and 20±4,respectively,with a statistically significant difference between the two groups (t=2.812,P＜0.05).(4) Follow-up:124 patients after propensity score matching were followed up for 6-37 months,with a median time of 25 months.During the follow-up,no severe surgery-related complications such as obstruction of input or output loop and dumping syndrome were found in the two groups within 3 months after operation.The 2-year overall survival rate was 82.1％ and 75.2％ in the robotic and laparoscopic group,with no statistically significant difference between the two groups (x2 =0.436,P＞0.05).Conclusions Compared with laparoscopic surgery,Da Vinci robotic distal gastrectomy for gastric cancer has advantages in postoperative recovery and minimally invasion.There are similar 2-year overall survival rates in the two groups.

Objective:To investigate the application value of enhanced recovery after surgery (ERAS) in totally Da Vinci robotic total gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 97 patients with gastric cancer who underwent totally Da Vinci robotic total gastrectomy in the First Affiliated Hospital of Nanchang University between January 2016 and February 2019 were collected.There were 57 males and 40 females, aged (59±10)years, with a range from 35 to 60 years. Of the 97 patients, 52 receiving perioperative management using ERAS were allocated into ERAS group, and 45 receiving traditional perioperative management were allocated into traditional group. Observation indicators: (1) intraoperative situations; (2) postoperative situations. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was analyzed using the t test. Count data were described as absolute numbers, and the chi-square test was used for comparison between groups. Repeated measurement data were analyzed by ANOVA. Comparison of ordinal datas was analyzed using the Mann-Whitney U test. Results:(1) Intraoperative situations: patients in the ERAS group and traditional group underwent totally Da Vinci robotic total gastrectomy for gastric cancer successfully. Cases with Roux-en-Y anastomosis or uncut Roux-en-Y anastomosis (methods of digestive reconstruction), operation time, volume of intraoperative blood loss for the ERAS group were 25, 27, (205±28)minutes, (176±80)mL, respectively, versus 21, 24, (199±31)minutes, (182±81)mL for the traditional group, showing no significant difference in the above indicators between the two groups ( χ2=0.02, t=1.00, 0.37, P>0.05). (2) Postoperative situations: time to first out-of-bed activities, time to first anal flatus, time to initial liquid food intake, time to abdominal drainage tube removal, cases with postoperative complications, the number of lymph node dissected, cases in stage Ⅰ, Ⅱ, Ⅲ of postoperative tumor staging, duration of postoperative hospital stay, hospitalization expenses were (1.85±0.29)days, (2.90±0.47)days, (2.53±0.28)days, (5.72±0.95)days, 6, 28±8, 4, 25, 23, (6.43±0.52)days, (60 222±3 888)yuan in the ERAS group and (3.04±0.39)days, (3.82±0.36)days, (4.24±0.30)days, (6.75±0.48)days, 5, (27±6)days, 3, 20, 22, (8.47±0.69)days, (64 197±3 369)yuan in the traditional group, respectively. There were significant differences in the time to first out-of-bed activities, time to first anal flatus, time to initial liquid food intake, time to abdominal drainage tube removal, duration of postoperative hospital stay and hospitalization expenses between the two groups ( t=17.19, 10.69, 29.02, 6.58, 16.57, 5.34, P<0.05). There was no significant difference in the postoperative complications, the number of lymph node dissected, or postoperative tumor staging between the two groups ( χ2=0.01, t=0.68, Z=-0.46, P>0.05). From 2 hours after anesthesia awakening to 48 hours after surgery, the visual analog pain scores were changed from 3.06±0.29 to 2.13±0.32 in the ERAS group, and from 4.11±0.74 to 3.26±0.42 in the traditional group, respectively, showing a significant difference in the changing trend between the two groups ( F=264.45, P<0.05). There was no death or readmission in the postoperative 30 days. Conclusions:ERAS applied in the totally Da Vinci robotic total gastrectomy is safe and effective, which is associated with faster gastrointestinal function recovery, shorter hospital stay, better pain control, and quicker recovery afer surgery.

Objective:To explore the clinical efficacy of a retrograde pubic ramus intramedullary nail (RPRIN) in the treatment of anterior pelvic ring fractures.Methods:A retrospective study was conducted to analyze the 14 patients with anterior pelvic ring fracture who had been treated and followed up at Department of Traumatic Surgery, Tongji Hospital From June 2020 to February 2021. There were 10 males and 4 females with an age of (44.8±12.5) years. By the AO/OTA classification for pelvic fractures, 5 cases were type 61-A, 4 cases 61-B, and 5 cases type 61-C; by the Nakatani classification, 1 case belonged to unilateral zone Ⅰ fracture, 5 cases to unilateral zone Ⅱ fracture, 2 cases to unilateral zone Ⅲ fracture, 3 cases to right zone Ⅱ and left zone Ⅲ fracture, 2 cases to zone Ⅲ fracture on both left and right sides, and 1 case to zone Ⅱ fracture on both sides. The time from injury to operation was (7.8±1.8) days. All the anterior pelvic ring fractures were fixated with a RPRIN. The time and fluoroscopic frequency for placement of every single RPRIN, quality of fracture reduction, and pelvic function and incidence of postoperative complications at the last follow-up were recorded.Results:A total of 18 RPRINs were placed in the 14 patients. For placement of each RPRIN, the time was (35.9±8.6) min, and the fluoroscopic frequency (22.8±1.9) times. No complications such as infection occurred at any surgical incision after RPRIN placement. According to the Matta scoring, the quality of postoperative fracture reduction was assessed as excellent in 7 cases, as good in 5 cases and as fair in 2 cases. The 14 patients were followed up for (18.1+1.5) months. Their X-ray and CT images of the pelvis at the last follow-up showed that the fractures healed well and the intramedullary nails were placed in the cortical bone of the anterior ring of the pelvis. According to the Majeed scoring at the last follow-up, the pelvic function was assessed as excellent in 10 cases, as good in 3 cases and as fair in 1 case. One patient reported discomfort during squatting 2 months after operation but the symptom improved 3 months later without any special treatment. No patient experienced such complications as displacement or slippage of RPRIN, or pain at the insertion site.Conclusion:RPRIN is effective in the treatment of anterior pelvic ring fractures, showing advantages of small surgical incision, limited intraoperative fluoroscopy and short operation time.

Objective: To describe the epidemiological characteristics of a cluster of COVID-19 cases reported in Baodi district of Tianjin as of 18 February, 2020, which might be associated with the exposure in a local department store, and provide suggestions for prevention and control strategy development. Methods: The basic characteristics, time and area distributions, clinical manifestations, epidemiological history and transmission mode of the COVID-19 cases associated with the department store exposure were analyzed. Results: A total of 40 COVID-19 cases were associated with the department store exposure, accounting for 75.47% of the total confirmed cases (53 cases) reported in Baodi district. The cases were mainly at the age of 60 years or older (35.00%) and farmers (40.00%). The main clinical manifestations included fever (95.00%), cough (35.00%), and diarrhea (15.00%). The proportion of confirmed severe cases was 32.50%. The incidence curve showed that the incidence peak occurred on 31 January, 2020. Among the 40 cases, 6(15.00%) were department store employees, 19(47.50%) were customers and 15(37.50%) were close contacts (secondary cases). The first case occurred on 21 January, 2020, this case was a department store employee who had a purchasing history at whole sale markets in other provinces and cities before the onset, and 3 employees were still on duty after symptom onsets. The median of the incubation period of customer cases was 6 days, and the median of the interval between onset and medical treatment of customer cases was 7 days. Conclusion This was a cluster epidemic of COVID-19, which might be associated with the exposure in the department store. By now, the current prevention and control measures have achieved satisfied effects.

Objective To investigate the geographical distribution and seasonal fluctuations of visceral leishmaniasis vectors sandflies in Henan Province in 2023, so as to provide insights into the prevention and control of visceral leishmaniasis vectors. Methods A total of 23 counties (districts) were sampled from 18 cities of Henan Province from May to September, 2023 as sandfly surveillance sites, and sandflies were captured using human capture and light trapping methods. Following morphological identification, the changes in the sandfly density were calculated at different months and in different breeding habitats. Results A total of 406 light traps were set at sandfly surveillance sites in Henan Province from May to September, 2023, and a total of 3 137 female sandlies were captured, with an average density of 7.73 sandlies/(light·night). A total of 1 494 Phlebotomus chinensis sandflies were captured, including 1 222 female sandflies, with an average density of 3.01 sandflies/(light·night), and the highest density of P. chinensis was found in Gongyi City [17.00 sandflies/(light·night)]. A total of 5 544 sandflies were captured using the human capture method, including 230 P. chinensis, and the density of P. chinensis appeared a unimodal distribution, with a peak in early July [5.81 sandflies/(light·night)]. Among different breeding habitats, the highest P. chinensis density was detected in pigpens [4.50 sandflies/(light·night)]. Conclusions P. chinensis was predominantly distributed in hilly areas of northern and central-western Henan Province in 2023, and the sandfly density appeared a unimodal distribution. Intensified monitoring of visceral leishmaniasis vectors is recommended.

Objective To analyze the characteristics of visceral leishmaniasis cases in Henan Province, so as to provide insights into formulation of the visceral leishmaniasis control srtrategy. Methods All epidemiological data of reported visceral leishmaniasis cases in Henan Province from 2021 to 2023 were retrieved from the National Notifiable Disease Report Information Management System of Chinese Center for Disease Control and Prevention, and the epidemiological features and diagnosis of visceral leishmaniasis cases were descriptively analyzed. Results A total of 93 visceral leishmaniasis cases were reported in Henan Province from 2021 to 2023, with a male to female ratio of 2.58∶1, and including 2 imported cases from other provinces and 91 local cases. The number of visceral leishmaniasis cases peaked during the period between March and May, and between July and October. The reported visceral leishmaniasis cases had ages of 7 months to 74 years, with the largest number of cases found at ages of 0 to 9 years (26 cases, 27.96%), followed by at ages of 60 to 70 years (24 cases, 25.81%). Farmer (47 cases, 50.54%) and diaspora children (19 cases, 20.43%) were predominant occupations, and 91 local visceral leishmaniasis cases were found in 6 cities of Zhengzhou, Luoyang, Anyang, Hebi, Sanmenxia and Xuchang. The median duration from onset of visceral leishmaniasis to diagnosis was 20 days, and there were 25.81% (24/93) cases with 10 days and less duration from onset to diagnosis, 38.71% (36/93) cases receiving diagnosis at 11 to 30 days following onset, and 35.48% (33/93) cases receiving diagnosis for more than 30 days following onset. All cases were predominantly diagnosed in province- (60.00%) and city-level (28.89%) medical institutions. Conclusions The number of visceral leishmaniasis is on the rise in Henan Province, with a gradually expanding coverage. Intensified monitoring of visceral leishmaniasis cases, dogs, and vectors, dog management, sandflies control and improved individual protection are recommended to prevent the spread of visceral leishmaniasis.
