The increased level of fibrinogen (Fg) is an independent factor that resulting in the occurrence of ischemic cardio-cerebrovascular diseases. The Fg level is correlated with heredity, age, sex, obesity, lipid, smoke, inflammation and infection, and the pathogenic effect of genetic factor has been increasingly receiving attention. In recent years, more than 10 FgBβ gene polymorphisms have been reported, among them, - 148C/T, - 455G/A, and - 854G/A are considered to be significantly correlated with the increased level of Fg, and may be one of the most key factors in influencing the genetic risk factors of the occurrence of ischemic cerebrovascular disease.

Objective To explore the factors which could lead to a preoperative diagnosis and to guide the management of cholecystoduodenal fistula (CDF).Method The experience on the diagnosis and treatment of 22 patients with CDF were retrospectively studied.These patients came from 1242 patients who received biliary tract operation in our hospital from 2001 to 2012.Results 64％ (14 of 22 patients) had 3 out of 5 of the following symptoms/signs:(1) symptoms of recurrent chills and fever,with no or only mild jaundice; (2) significant atrophy or disappearance of gallbladder on computed tomography (CT) ; (3) CT revealed complex anatomy in right upper abdomen with dilated loops of bowel; (4) ultrasound or CT revealed pneumobilia or pneumo-gallbladder; (5) barium study or duodenal endoscopy revealed obvious deformation in duodenal bulb or abnormal opening.There was no perioperative death.Morbidities included biliary fistula which presented on postoperative day 6 and day 7 in 2 patients,respectively.The daily volume of bile drainage was about 500 ml,and the biliary fistula healed after a month of conservative treatment.In addition,there were 6 patients who had infected wound,8 patients with right pleural effusion,and 8 patients with residual calculi.There was no intestinal fistula or biliary stricture.Conclusions Careful preoperative history taking and CT/uhrasound studies significantly improved the diagnostic rate of CDF.Individualized treatment reduced complications and improved clinical results.

Parathyroid carcinoma is a rare sporadic disease.Clinical manifestations include hypercalcemia,increased urinary calcium and urinary calculus,osteoporosis,and pathologic fracture.While this patient complained of pollakiuria,urgency,and painful urination,thus might lead to misdiagnosis or missing of diagnosis of parathyroid carcinoma.This article is herewith presented to call attention to discovery,diagnosis,and treatment of parathyroid carcinoma.

Objective: To observe hypoglycemic effects of Yunu Decoction, Zuogui Pill and Shenqi Pill, three compound traditional Chinese herbal medicines, in treatment of diabetes mellitus induced by alloxan in rats, and to compare the therapeutic effects among the three recipes for nourishing yin, clearing away heat, and nourishing yin and warming yang. Methods: Diabetes mellitus was induced in rats with alloxan at a dose of 60 mg/kg via tail vain injection. The diabetic rats were randomly divided into four groups: alloxan model group, Yunu Decoction-treated group, Zuogui Pill-treated group and Shenqi Pill-treated group. Rats in the three recipe groups were administered intragastrically with water extraction of Yunu Decoction, Zuogui Pill, and Shenqi Pill accordingly for 10 days. Then the level of blood glucose was measured by glucose oxidase method and the glucose tolerance was determined. Results: Compared with the normal rats, blood glucose level in the alloxan model group was obviously increased (P<0.05). Glucose levels in the three recipe groups were obviously decreased as compared with the alloxan model group (P<0.05), and glucose level in the Yunu Decoction-treated group after treatment was significant lower than before treatment (P<0.05). The glucose tolerance test indicated that rats in the alloxan model and three recipe groups revealed impaired glucose tolerance as compared with the normal rats, and there were no significant differences between the alloxan model group and the three recipe groups. Conclusion: Yunu Decoction, Zuogui Pill and Shenqi Pill can effectively decrease the glucose level of the rats with diabetes mellitus induced by alloxan, and Yunu Decoction showed the best therapeutic effects. The glucose tolerance test shows that the three recipes cannot correct the abnormal metabolism of glucose.

Objective: To compare the effects of modified Thrombolysis in Cerebral Infarction score (mTICI) 2b and mTICI 3 reperfusion on lesions′ changes and prognosis in patients who underwent endovascular therapy within six hours after onset. Methods: A retrospective analysis was conducted on 94 patients with acute large intracranial artery occlusion of the anterior circulation who achieved reperfusion sucesssfully by endovascular therapy within 6 hours after onset in the Department of Neurology, Nanjing First Hospital from October 2016 to March 2019. The effects of mTICI 2b and mTICI 3 reperfusion on lesions′ changes and prognosis of patients were compared. The primary endpoint was the modified Rankin Scale (mRS) score at 90 days; the secondary endpoints were the early neurological deficit score, the mortality at 90 days, the volume of infarction at 24 hours, the changes in infarct volume for 24 hours and the rate of symptomatic intracerebral hemorrhage (sICH) , reocclusion and hemorrhagic transformation. Results: In all patients, 35 cases received mTICI 2b reperfusion and 59 cases received mTICI 3 reperfusion. Compared with mTICI 2b group (10.00 (3.00, 16.00)), the early neurological deficit score at seven days of mTICI 3 group (6.00 (1.00,11.50)) was lower (Z=-2.004, P=0.045) . However, there were no statistically significant differences in mRS score at 90 days, early neurological deficit score at 24 hours and 3 days, mortality at 90 days, volume of infarction at 24 hours, the changes in infarct volume for 24 hours, and the rate of sICH, reocclusion, and hemorrhagic transformation between the two groups. Conclusion For patients with large intracranial artery occlusion of the anterior circulation within six hours after onset, achieving mTICI 3 reperfusion after endovascular therapy can improve the early neurological function more effectively, but the effects on 90-day functional outcome are similar to that of mTICI 2b reperfusion.

Objective To observe the effects of interfering Twist expression on glycolysis in pancreatic cancer PANC1 cells and explore the potential mechanism.Methods Twist targeting siRNA (siTWIST) was designed and synthesized,and pancreatic cancer PANC1 cells were transfected with siTWIST using liposome,with nonspecific siRNA (siNC) transfected cells as negative control group and untransfected cells as blank control group.RT-PCR and Western blot were used to detect the expression levels of Twist mRNA and protein,and Akt and p-Akt protein expression in different groups;cell proliferation was detected by MTT;and glycolysis key enzyme (pyruvate kinase and hexokinase) activity and the content of lactic acid in the supernatant of culture fluid were detected.Results Twist mRNA level in control group,siRNA group and siTwist group expression was 1.00 ± 0.09,1.01 ± 0.08 and 0.36 ± 0.02;Twist protein level was 0.41 ± 0.05,0.42 ± 0.04 and 0.12 ± 0.06;the mRNA and protein expression in siTWIST group was obviously lower than those in control group and the difference was statistically significant (P ＜ 0.05).The cell survival rate was (100.02± 9.36)％,(100.01 ± 10.25)％ and (59.32± 7.26)％,which in siTWIST group was obviously lower than that in control group;pyruvate kinase activity was (0.73 ± 0.05)U/mg,(0.72 ± 0.08) U/mg and (0.43 ± 0.05) U/mg;the activities of hexokinase were (4.98 ± 0.48) U/mg,(4.96 ± 0.52) U/mg and (2.54 ± 0.21) U/mg;the content of lactic acid was (20.36 ± 2.61) mmol/L,(20.64 ± 3.05) mmol/L and (9.48 ± 1.09) mmol/L;the ratio of p-Akt/Akt was 0.65 ± 0.04,0.63 ± 0.07,and 0.25 ± 0.04,which in siTWIST group was obviously lower than that in control group.Conclusions Interference with Twist expression could inhibit the proliferation and glycolysis pathway in pancreatic cancer cells,and the mechanism may be related to the Akt signaling pathway.

Objective Hypothyroidism(HypoPT) is one of the most common complications of thyroid reoperation,and hypocalcemia caused by HypoPT is a difficult problem in clinical practice.This study aims to investigate the risk factors for hypoealcemia after reoperation of thyroid cancer.Methods Data of 106 patients who underwent reoperation for thyroid cancer from 2013 to 2018 were retrospectively analyzed.According to the parathyroid area involved in the reoperation,the reoperation was graded:low-risk group,intermediate-risk group and high-risk group.Parathyroid hormone(PTH) and total calcium(Ca) levels were monitored at 12 to 24 hours after surgery.The follow-up period was at least 6 months.The PTH cut-off values of postoperative hypocalcemia were analyzed by ROC curve.The chi-square test and logistic regression analysis were used to analyze the risk factors of postoperative hypocalcemia.Results The incidence of transient HypoPT after reoperation was 35％,and the permanent HypoPT was 1.9％.The grade of reoperation was positively correlated with postoperative HypoPT.The ROC curve showed that the PTH cut-off values of postoperative hypocalcemia was 15 pg/ml and area under curve(AUC) was 0.636(95％ CI:0.530-0.742,P＜0.017).Univariate and multivariate analysis showed that reoperation grade and postoperative PTH＜15 pg/ml were independent risk factors for postoperative hypocalcemia.Conclusion The grade of reoperation and postoperative PTH value ＜15 pg/ml can predict postoperative hypocalcemia.

Objective To explore the feasibility and clinical outcome of lateral cervical incision via sternocleidomastoid intermuscular approach(SMIA)in the treatment of primary hyperparathyroidism.Methods The clinical data of 64 patients with primary hyperparathyroidism who underwent unilateral parathyroid surgery in the First Affiliated Hospital,School of Medicine of Zhejiang University from January 2019 to June 2022 were retrospectively analyzed.They were divided into lateral cervical incision via sternocleidomastoid intermuscular approach group(SMIA group)and linea alba cervicalis approach group(LACA group)based on the surgical incision and access route.The differences in clinical features,surgery-related outcomes and postoperative functions of the anterior cervical region were compared between the two groups.The EQ-5D-5L scale was used to assess the subjective feeling of postoperative neck discomfort,while the Hollander Wound Assessment Scale was used to assess the clinical outcome of incision healing.Results There were no statistical differences between the two groups of patients in terms of age,gender,intraoperative bleeding,parathyroid hormone or blood calcium levels before and after surgery(P＞0.05).The duration of surgery was significantly shorter in the SMIA group than in the LACA group[(39.77±5.69)min vs.(54.41±4.66)min].There was a statistical difference between the two groups in functional protection of the anterior cervical region at 1 month and 12 months after surgery(1 month,84.67±3.74 vs.79.47±5.38,P＜0.001;12 months,93.80±2.52 vs.89.94±2.39,P＜0.001),and the SMIA group was better than the LACA group.The Hollander Incision Assessment Scale scores of the SMIA group were better than those of the LACA group at 6 months and 12 months after surgery,and the difference was statistically significant(6 months,1.93±0.58 vs.2.41±0.66,P=0.003;12 months,1.03±0.67 vs.1.74±0.62,P＜0.001).Conclusion Parathyroidectomy via sternocleidomastoid intermuscular approach through lateral cervical incision is a simple,safe and effective surgical procedure,which makes it easier to search for parathyroid lesions and shortens the surgical time compared with the traditional incision,and has obvious advantages in the protection of anterior cervical region function.

Objective:To compare the effects of intensive and standard blood pressure control on the outcomes of patients with acute ischemic stroke in the anterior circulation who have successfully recanalized after endovascular therapy (EVT).Methods:A multicenter, open-label, blinded-endpoint, randomized controlled design was used. Patients with anterior circulation stroke received EVT and successfully recanalized in Nanjing First Hospital, Nanjing Medical University and several branch hospitals from July 2020 to October 2022 were prospectively included. They were randomly divided into the intensive blood pressure control group (target systolic blood pressure [SBP] 100-120 mmHg) or the standard blood pressure control group (target SBP 121-140 mmHg). The blood pressure of both groups needs to achieve the target within 1 h and maintain for 72 h. The primary outcome endpoint was outcome at 90 d, and the good outcome was defined as a score of 0-2 on the modified Rankin Scale. Secondary outcome endpoints included early neurological improvement, symptomatic intracranial hemorrhage (sICH) within 24 h, and death and serious adverse events within 90 d.Results:A total of 120 patients were included, including 63 in the intensive blood pressure control group and 57 in the standard blood pressure control group. There was no statistically significant difference in baseline characteristics between the two groups. The SBP at 72 h after procedure was 122.7±8.1 mmHg in the intensive blood pressure control group and 130.2±7.4 mmHg in the standard blood pressure control group, respectively. There were no significantly differences in the good outcome rate (54.0% vs. 54.4%; χ2=0.002, P=0.963), the early neurological improvement rate (45.2% vs. 34.5%; χ2=1.367, P=0.242), the incidence of sICH (6.3% vs. 3.5%; P=0.682), mortality (7.9% vs. 14.0%; χ2=1.152, P=0.283) and the incidence of serious adverse events (12.7% vs. 15.8%; χ2=0.235, P=0.628) at 90 d between the intensive blood pressure control group and the standard blood pressure control group. Conclusion:In patients with anterior circulation stroke and successful revascularization of EVT, early intensive blood pressure control don’t improve clinical outcomes and reduce the incidence of sICH.

【Objective】 To investigate whether the blood donors' coagulation status may lead to apheresis platelet aggregation in vitro. 【Methods】 Thirty blood donors with aggregation in apheresis platelets collected by AMICUS blood cell separator no less than 3 times previously and occurred when the last time of apheresis donation were observed in aggregated group (referred to as the experimental group); Thirty donors without aggregation in apheresis platelets collected by AMICUS blood cell separator no less than 3 times were observed in the control group simultaneously. The basic platelet parameters in the two groups, including Plt, MPV, PDW, Pet, P-LCR were detected by automatic blood cell analyzer (BC-3000Plus), and thromboelastogram indexes including reaction time(R), kinetics time(K), kinetics of clot development(α), maximum amplitude (MA) and coagulation index(CI) were tested by Thrombosis elastography (TEG) before collection. With SPSS24.0 software, t test was used to compare the differences between the two groups. 【Results】 The CI value in experimental group was significantly different from that of the control group (0.48± 1.00 vs -0.99 ±1.96, P< 0.05), and there was no significant difference in all above basic platelet parameters and other TEG parameters (P>0.05 ) . 【Conclusion】 The coagulation status of blood donors may be an independent risk factor for the in vitro aggregation of apheresis platelets.
