Objective To explore the diagnosis and treatment of cystic dilatation of the cystic duct in adults.Method Clinical data of 25 cases of the cystic dilatation of cystic duct in adults in 3 hospitals in Songhuajiang river drainage area from 1991 to 2012 confirmed by surgery were analyzed retrospectively.Results The 25 cases were with manifestations of chronic cholecystitis,and 14 patients with right upper quadrant recurrent biliary colic and nausea,vomiting and other gastrointestinal symptoms,9 patients with yellowish discoloration of sclera and skin,and fever.Ultrasonography was done in 25 cases,ERCP in 16 cases and MRCP in 9 cases,displaying liquid dark area of diameter from 1.6 cm × 1.6 cm to 2.5 cm ×2.5 cm in the gallbladder tube suspective of calculi,and characteristic dumbbell shape image.Preoperative diagnosis was cystic duct cyst with stones or gallstones which was confirmed by surgery.Gallbladder and cyst resection was performed in all 25 cases,and bile duct jejunum Roux-en-Y anastomosis was done in 2 of these cases because of introgenic bile duct injury.Conclusions Cysts of the cystic duct is the special type (Ⅵ type) of choledochocele,and its prognosis is good after surgical treatment.

Objective:To analyze and compare difference of ultrasonic blood flow of left internal mammary artery(LIMA) and right internal mammary artery(RIMA)as graft to left anterior descending artery(LAD) in patients undergoing off-pump coronary artery bypass grafting(OPCABG).Methods:From October 2017 to October 2019, a total of 363 patients who underwent OPCAB including 329 patients in LIMA-LAD group and 34 patients in RIMA-LAD group, were included in this study. Transthoracic ultrasound examination on IMA was performed before OPCABG. The blood flow , the value of PI(pulsation index) and diastolic flow(DF) of LIMA and RIMA to left anterior descending were measured and recorded by intraoperative TTFM. Patients underwent coronary artery CT examinations at 1 week after OPCABG to discover the patency of grafts.Results:The pre-operative diameter of RIMA was larger and the blood flow and pulsation index of RIMA was better than that of LIMA before OPCABG( P<0.001). But there was no significant difference in the flow, pulsation index and DF value of graft between the two groups after IMA were anastomosed to LAD( P>0.05). In situ skeletonized graft of RIMA did not show the advantage of increased blood flow. Compared with the preoperative parameters of flow of internal mammary artery, both the left and right grafts of IMA were significantly better in blood flow and pulsation index( P<0.001). Considering the remarkable difference in age between the two groups, Flow, PI and DF were compared again after propensity score matching, and there was still no statistical difference between the two groups( P>0.05). A total of 313 patients in LIMA-LAD group completed coronary CTA examination one week after surgery, among which 4 grafts had different degrees of problems. A total of 34 patients in RIMA-LAD group completed coronary CTA examination, one case indicated that the CTA imaging in distal segment was not clear, and the other results had no obvious abnormality. There was no significant difference in postoperative rate of coronary CTA completion( P=0.381) and rate of graft failure( P=0.405) between the two groups. Conclusion:Compared with the preoperative parameters of blood flow of internal mammary artery, both the left and right IMA grafts are significantly better in flow and pulsation index. The pre-operative diameter of RIMA is larger and the blood flow and pulsation index of RIMA is better than that of LIMA before OPCABG. But there is no significant difference in the flow, pulsation index and DF value of graft between the two groups after IMA are anastomosed to LAD. In situ skeletonized graft of RIMA do not show the advantage of increased blood flow.

This study is to evaluate the therapeutic effect of fibroblast growth factor 21 (FGF21) on NAFLD in MSG-IR mice and to provide mechanism insights into its therapeutic effect. The MSG-IR mice with insulin resistance were treated with high dose (0.1 micromol.kg-1d-1) and low dose (0.025 micromol.kg-1d-1) of FGF21 once a day for 5 weeks. Body weight was measured weekly. At the end of the experiment, serum lipids, insulin and aminotransferases were measured. Hepatic steatosis was observed. The expression of key genes regulating energy metabolism were detected by real-time PCR. The results showed that after 5 weeks treatment, both doses of FGF21 reduced body weight (P<0.01), corrected dyslipidemia (P<0.01), reversed steatosis and restored the liver morphology in the MSG model mice and significantly ameliorated insulin resistance. Additionally, real-time PCR showed that FGF21 significantly reduced transcription levels of fat synthetic genes, decreased fat synthesis and promoted lipolysis and energy metabolism by up-regulating key genes of lipolysis, thereby liver fat accumulation was reduced and liver function was restored to normal levels. In conclusion, FGF21 significantly reduces body weight of the MSG-IR mice, ameliorates insulin resistance, reverses hepatic steatosis. These findings provide a theoretical support for clinical application of FGF21 as a novel therapeutics for treatment of NAFLD.

This study is to evaluate the therapeutic effect of fibroblast growth factor 21 (FGF21) on hypertension induced by insulin resistance in rats and to provide mechanistic insights into its therapeutic effect. Male Sprague-Dawley (SD) rats were fed with high-fructose (10%) water to develop mild hypertensive models within 4 weeks, then randomized into 4 groups: model control, FGF21 0.25, 0.1 and 0.05 micromol x kg(-1) x d(-1) groups. Five age-matched normal SD rats administrated with saline were used as normal controls. The rats in each group were treated once a day for 4 weeks. Body weight was measured weekly, systolic blood pressure (SBP) was measured noninvasively using a tail-cuff method, insulin sensitivity was assessed using oral glucose tolerance test (OGTT) and HOMA-IR assay. At the end of the treatment, blood samples were collected, and blood glucose, serum cholesterol, serum triglyceride and serum insulin were measured. The results showed that blood pressure of the rats treated with different doses of FGF21 returned to normal levels [(122.2 +/- 3.5) mmHg, P < 0.01] after 4-week treatment, whereas, SBP of untreated (model control) rats maintained a high level [(142.5 +/- 4.5) mmHg] throughout the treatment. The observation of blood pressure in 24 h revealed that SBP of FGF21 treated-rats maintained at (130 +/- 4.5) mmHg vs. (143 +/- 5.5) mmHg for model control (P < 0.01). FGF21 treatment groups improved serum lipids obviously, total cholesterol (TC) and triglyceride (TG) levels decreased significantly to normal levels. The serum NO levels of three different doses FGF21 treatment group were significantly higher than that of the model control group [(7.32 +/- 0.11), (7.24 +/- 0.13), (6.94 +/- 0.08) vs. (6.56 +/- 0.19) micromol x L(-1), P < 0.01], and the degree of improvement showed obvious dose-dependent manner, indicating that FGF21 can significant increase serum NO in fructose-induced hypertension rat model and improve endothelial NO release function. The results of OGTT and HOMA-IR showed that insulin resistance state was significantly relieved in a dose-dependent manner. Thus, this study demonstrates that FGF21 significantly ameliorates blood pressure in fructose-induced hypertension model by relieving insulin resistance. This finding provides a theoretical support for clinical application of FGF21 as a novel therapeutics for treatment of essential hypertension.

Objective:To explore the prognosis and risk factors for conversion from off-pump coronary artery bypass grafting (OPCABG) to coronary bypass grafting (CABG) during surgery.
Methods: We retrospectively analyzed 2613 patients with elective OPCAB in our hospital from 2001 to 2012, there were 62 (2.37%) patients converted to CABG during the operation as Conversion group, the rest 2551 patients were set as Non-conversion group. The peril-operative baseline clinical data and prognosis condition were compared between 2 groups. The risk factors causing the in-operative conversion were studied with binary logistic regression analysis.
Results: The total conversion rate was 2.37%, including 42 patients of hemodynamic instability, 6 with dififculty of target vessel exposure, 9 with malignant arrhythmia, 3 with graft occlusion and 2 patients with other reasons. Compared with Non-conversion group, the Conversion group had increased post-operative drainage and ventilation time, higher rates of second thoracotomy for stop bleeding and higher peril-operative mortality. Binary logistic regression analysis indicated that chronic obstructive pulmonary disease, previous history of CABG, NYHA class≥3, LVEF≤40%and left main disease were the independent risk factors for in-operative conversion.
Conclusion: Conversion from OPCAB to CABG during the operation would be result in signiifcantly higher morbidity and mortality in relevant patients.

Objective:To study the etiology, diagnosis, treatment and prognosis of urethra hemangioma by ret-rospective analysis of the clinical literatures. Methods: Three patients underwent transurethral plasmakinetic vapor-ization(TUPKVP), and two patients were performed with traditional operation. The clinical data of 5 patients was analyzed in combination with related literature. Results: Four patients were cured after one treatment, and one pa-tient was experienced TUPKVP three times before the bleeding was totally controlled, urethral hemangioma were confirmed by pathological examination. No recurrence and short-term or persistent complication was reported with a minimum follow-up of 12 months (from 12 months to 48 months). Conclusions:The urethra hemangioma located at the external orifice of urethra could be treated with traditional operation or TUPKVP is a minimally invasive, safe and effective method for the treatment for urethra hemangioma. Prognosis of urethral hemangioma is good.

Objective:To explore the value of morphometric analysis program (MAP) in detecting focus of pediatric epilepsy related to focal cortical dysplasia (FCD) II.Methods:A retrospective analysis was performed; 42 epilepsy children with FCD II and postoperative Engel grading I in Department of Neurosurgery, He'nan Provincial People's Hospital from June 2020 to January 2023 were enrolled. Preoperative MRI data were analyzed by MAP. Difference in general data and focus detection rate by MRI and MAP were compared between the positive MAP group and negative MAP group, and consistency of MAP positive areas (true positive MAP and false positive MAP by postoperative CT) with interictal PET low metabolism positive areas was analyzed.Results:Of the 42 children, 28 had positive MAP and 14 had negative MAP in the epileptogenic focus. Gender was statistically different between positive MAP group and negative MAP group ( P<0.05). MAP had significantly better performance in focus detection compared with MRI (28/42 vs. 19/42, P<0.05). Significant difference was noted between consistency of true positive MAP area with interictal PET low metabolism positive areas (40/43) and that of false positive MAP area with interictal PET low metabolism positive areas (4/33, P<0.05). Conclusion:MAP can improve the focus detection rate of pediatric epilepsy related to FCD II effectively, and PET contributes to rule out false positive results.

Diabetes mellitus erectile dysfunction(DMED)is a common diabetic-related vascular,endo-crine and neuropathy in clinical practice,and patients with DMED often present with symptoms such as difficulty in erection,prolonged erection time,poor hardness,and short sexual intercourse.The etiological mechanism is complex,and it is often closely related to many factors such as oxidative stress(OS),inflammatory response,and neurological and endocrine lesions,which often cross-react and promote the progression of DMED lesions.In recent years,relevant studies have shown that OS and ferroptosis play a key role in DMED:OS can cause neuro-logical and Abnormal endocrine function,decreased synthesis or bioavailability of penile vascular endothelium,spongy endothelial cell dysfunction and decreased smooth muscle diastolic function,resulting in penile erectile dysfunction,and ferroptosis has also been confirmed to be closely related to DMED,controlling OS and ferroptosis to improve erectile function in diabetic patients is a reasonable and effective treatment pathway,but the mechanism of action of ferroptosis leading to DMED needs to be further studied.Therefore,this article reviews the latest infor-mation on the correlation between OS and ferroptosis and DMED,aiming to provide a useful reference for exploring the mechanism of DMED,clinical prevention and treatment of DMED,and providing potential directions for future research in this field.

Objective:To report the use of right internal mammary artery (RIMA) in coronary artery bypass grafting (CABG) in our center, summarize the purpose and configuration of RIMA graft in CABG.Methods:All clinical data of coronary artery bypass grafting patients in our center performed in the past 6 years were collected and analyzed retrospectively. Those patients were divided into RIMA group and non-RIMA group according to the use of RIMA. Propensity score matching had been performed before these data was compared. Surgical technique of use of RIMA was summarized.Results:1 537 CABG had been performed from January 1st, 2016 to October 31st, 2021 in our center. Of which, 128 cases were allocated to RIMA group. After propensity score matching having been performed, there was no difference in baseline data between the RIMA group and the non-RIMA group (128 cases), and the RIMA group had more grafts and arterial grafts than the non-RIMA group. The postoperative drainage volume in the RIMA group was more than that of the non-RIMA group. However, there was no statistical significance in difference of transfusion between two groups. Also, there was no difference in postoperative mechanical ventilation time, ICU time and length of stay postoperatively. The postoperative complications were similar between two groups. Postoperative patency rate of the RIMA graft was as high as 95.2%. The target vessels of RIMA included left anterior descending branch (45 cases), diagonal branch (19 cases), intermediate branch (12 cases). obtuse marginal or circumflex branch (16 cases), posterior descending branch (5 cases) and right coronary trunk (18 cases). 41 RIMA used as free grafts, 87 used as in situ grafts, of which 19 RIMA need lengthened by other graft vessels.Conclusion:The patency rate of RIMA graft is high and the application of RIMA do not increase the surgical risk significantly. However, there are versatile contour of RIMA grafts. It can be used as artery graft in selected patients.
