Objective To investigate the clinical efficacy of Guhong Injection for the treatment of patients with coronary microvascular dysfunction(CMD)of qi stagnation and blood stasis syndrome.Methods Sixty cases of patients with CMD of qi stagnation and blood stasis syndrome who were admitted to Guangdong Provincial Hospital of Chinese Medicine from June 2021 to August 2022 were randomly divided into the control group and the trial group according to the random number table method,with 30 cases in each group.The control group was treated with conventional western medicine,and the trial group was treated with Guhong Injection on the basis of treatment for the control group.The course of treatment for the two groups covered 10 days.The changes in traditional Chinese medicine(TCM)syndrome scores,and levels of lipid indicators,serum inflammatory factors and endothelial factors in the two groups were observed before and after treatment.After treatment,the clinical efficacy of the two groups was evaluated.Results(1)During the trial,three cases in the control group and two cases in the trial group fell off and a total of 55 cases were finally included in the statistical analysis of efficacy,including 27 cases in the control group and 28 cases in the trial group.(2)After 10 days of treatment,the total effective rate of the trial group was 89.29%(25/28),and that of the control group was 40.74%(11/27),and the intergroup comparison(tested by chi-square test)showed that the therapeutic efficacy of the trial group was significantly superior to that of the control group(P<0.01).(3)After treatment,the TCM syndrome scores of patients in both groups were decreased compared with those before treatment(P<0.05),and the decrease in the trial group was significantly superior to that in the control group(P<0.01).(4)After treatment,the levels of lipid indicators triglyceride(TG),total cholesterol(TC),and low-density lipoprotein cholesterol(LDL-C)in the two groups of patients were decreased compared with those before treatment(P<0.05),and the level of high-density lipoprotein cholesterol(HDL-C)was increased compared with that before treatment(P<0.05).The intergroup comparison showed that the decrease of TG,TC,and LDL-C levels as well as the increase of HDL-C level in the trial group was significantly superior to that in the control group(P<0.05 or P<0.01).(5)After treatment,the serum levels of inflammatory factors high-sensitivity C-reactive protein(hs-CRP),interleukin 6(IL-6)and tumor necrosis factor α(TNF-α)in the two groups of patients were decreased compared with those before treatment(P<0.05),and the decrease in the trial group was significantly superior to that in the control group(P<0.01).(6)After treatment,the serum level of endothelial factor nitric oxide(NO)in the two groups of patients was increased(P<0.05)and the serum endothelin 1(ET-1)level was decreased compared with that before treatment(P<0.05),and the increase of serum NO level,as well as the decrease of serum ET-1 level in the trial group was significantly superior to that in the control group(P<0.05 or P<0.01).Conclusion Based on the conventional treatment in western medicine,the application of Guhong Injection in the treatment of patients with CMD of qi stagnation and blood stasis syndrome exerts remarkable efficacy,which can effectively alleviate the symptoms,regulate the levels of blood lipids,reduce the inflammatory response,and improve the endothelial function.

Left atrial appendage closure(LAAC)is an important intervention method for preventing thromboembolic events in patients with non-valvular atrial fibrillation(NVAF).However,incomplete endothelialization following the procedure can impact its long-term efficacy and safety.This article proposes the view of qi flourishment promoting tissue regeneration based on the traditional Chinese medicine(TCM)theory of qi and blood,and explores diagnostic and therapeutic strategies for post-LAAC incomplete endothelialization by examining the theoretical connotation of qi flourishment promoting tissue regeneration and the relationship between qi and vascular endothelial cells.It is proposed that the primary pathogenesis in patients after LAAC is due to qi deficiency.Guided by the view of qi flourishment promoting tissue regeneration,therapeutic approaches such as tonifying qi to promote granulation,supplementing qi to activate blood circulation,and harmonizing the viscera can be employed to address incomplete endothelialization in NVAF patients following LAAC.Clinically,the qi-supplementing and blood-activating classic formula Neituo Shengji San,mainly composed of Astragali Radix,Glycyrrhizae Radix et Rhizoma,Olibanum,Myrrha,Paeoniae Radix Alb,Trichosanthis Radix,Salviae Miltiorrhizae Radix et Rhizoma,etc.,is usually utilized for modified use.Depending on the specific symptom patterns or pathogenesis characteristics of patients with incomplete endothelialization,this basic formula may be used by combining with Shengmai San or augmented with qi-supplementing and blood-activating herbs such as Chuanxiong Rhizoma,Fici Simplicissimae Radix,and Notoginseng Radix et Rhizoma to promote endothelialization.Diagnosing and treating post-LAAC incomplete endothelialization in NVAF patients following the view of qi flourishment promoting tissue regeneration,it is expected to offer a novel TCM perspective and therapeutic strategy to enhance post-LAAC outcomes and address the challenge of incomplete endothelialization.This approach can further serve as a reference for TCM clinicians to manage endothelialization issues following implantation procedures.

Objective: To evaluate the effects of office blood pressure(OBP)combined with ambulatory blood pressure monitoring(ABPM)on the diagnosis of hypertension. Methods: The residents aged 35-79 years without hypertension history,whose casual OBP were 120~159 mm Hg/80~99 mm Hg,were enrolled from 4 communities of Hangzhou and Zhuji from 2015 to 2018. They were performed OBP measurements on other two days in 4 weeks and ABPM in a week. There were 2 criteria of OBP as elevated OBP on the first day or in 3 different days,and 4 criteria of ABPM as elevated mean BP in 24 hours, daytime, nighttime and either of the above time. Receiver operating characteristic(ROC)curve was employed to evaluate the effects of different OBP criteria combined with ABPM criteria on the diagnosis of masked hypertension(MH)and white-coat hypertension(WCH). Results: Taking 3-day-OBP as a golden standard,the 1-day-OBP with 4 ABPM criteria had the areas under the ROC curve(AUC)of 0.79-0.81,sensitivity of 57.58%-62.77% and specificity of 100.00% in MH;had the AUC of 0.95-0.98,sensitivity of 100.00% and specificity of 88.96%-96.80% in WCH. The Kappa values were all less than 0.6,known as low consistency. Taking either time of ABPM as a golden standard,24 hours,daytime and nighttime ABPM criteria with OBP had the AUC of 0.90-0.92,sensitivity of 79.17%-83.90% and specificity of 100.00% in MH(all Kappa>0.6),when with 1-day-OBP,the Kappa values were all more than 0.8,known as high consistency;had the AUC of 0.95-1.00,sensitivity of 100.00% and specificity of 89.54%-99.37% in WCH,the Kappa values of daytime ABPM were all more than 0.6,known as high consistency. Conclusions If limited by options, 1-day-OBP could be used instead of 3-day-OBP for detection of WCH or exclusion of MH yet with less accuracy; 24 hours or daytime ABPM instead of either time of ABPM was reliable.

Objective: To evaluate the efficacy and safety of Hong's pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy. Methods: A retrospective analysis was carried out on 184 patients who underwent laparoscopic pancreaticoduodenectomy using Hong's pancreaticojejunostomy (the Hong’s pancreaticojejunostomy group) compared with 100 patients who underwent laparoscopic pancreaticoduodenectomy using traditional pancreaticojejunostomy (the traditional pancreaticojejunostomy group) at Department of Second Hepatobiliary and Pancreatic Surgery, the First Bethune Hospital of Jilin University, from April 2016 to December 2018. The differences between the two anastomotic methods in operation time, pancreaticojejunostomy time, intraoperative blood loss, postoperative hospital stay, postoperative complications, and incidences of pancreatic fistula were compared. Results: The operation time, pancreaticojejunostomy time and intraoperative blood loss of the Hong's pancreaticojejunostomy group were significantly less than the traditional pancreaticojejunostomy group [(278.2±49.3) min vs. (337.3±67.4) min, (33.7±6.6) min vs. (46.8±8.5) min, (123.1±44.7) ml vs. (203.8±138.6) ml], respectively, (all P<0.05). There were no significant differences in postoperative hospital stay and pancreatic fistula rates between the two groups (all P>0.05). Conclusions Hong's pancreaticojejunostomy was safe, rapid and effective compared with traditional pancreaticojejunostomy. It did not increase the incidence of pancreatic fistula.

Objective:To compare the three effects of lidocaine in the prevention of general anesthesia in elderly patients.Methods:A total of 120 elderly patients (65-85 years old) underwent anesthesia with general anesthesia (ASA) Ⅰ ～ Ⅱ were randomly divided into thyrocricocentesis group (group H),throat surface anesthesia group (Group Y),intravenous injection group (group J) and control group (group D).Group H was injected with lidocaine for surface anesthesia;group Y used laryngeal spray for laryngeal sprayed lidocaine for surface anesthesia;group J was anesthetized induction of intravenous lidocaine to prevent intubation reaction;group D the control group was not treated with lidocaine.(SBP) and heart rate (HR) were measured before and after induction (T0),tracheal intubation (T1) and 1 (T2),3 (T3) and 5 min (T4),the changes of hemodynamics related indexes were compared.Results:Compared with the same group of T0,the SBP and HR of four groups of T1 moments were significantly decreased (P ＜0.05);In the other three groups,SBP was significantly increased at T2 and T3 (P ＜0.05),HR ofT2 was significantly increased (P ＜0.05);Compared with group D,SBP and HR in group H,Y and J were significantly different at T2,T3 and T4,he difference was statistically significant (P ＜0.05);but there was no statistically significant difference between the three groups (P＞ 0.05).Conclusion:The three ways of lidocaine can be used to prevent the general anesthesia reaction in elderly patients,the effect of three ways is parallel.However,cricothyroid membrane puncture increased the patient's pain,throat spray method increased the cumbersome operation and enhanced the cost of the patient,and intravenous injection method is simple and worthy of popularization and application in clinic.

About 30%-50% of colorectal cancer patients would develop recurrence and metastasis. At present, there is still a lack of effective evaluation method for recurrence, metastasis and prognosis. In recent years, a great progress about circulating tumor cells (CTC) in diagnosis and treatment of colorectal cancer has been made. The most common CTC detection methods include immunocytochemistry, flow cytometry, PCR, immunomagnetic separation, optical fiber array scanning and CTC chip. Based on present studies, researchers reach the consensus that CTC is clinically valuable in the following aspects: detection of occult metastasis, monitor of disease progress and evaluation of response to treatment. With recent development of clinical specialization, multi-disciplinary treatment (MDT), gene detection and targeted therapy, individualized treatment may greatly improve overall survive and disease-free survival of colorectal cancer patients. However, the methods above depend on tumor tissues that are always impractical to obtain for late stage and non-surgery patients. Moreover, the size of specimen is always small, making gene expression and mutation detection difficult. CTC detection may solve such problems based on molecular biology with high plausibility and repeatability. Therefore, CTC detection can be used as a new diagnosis tool. It is believed that CTC detection will play an important role in early diagnosis, evaluating recurrence, metastasis, making individualized treatment and predicting prognosis.
