Objective:To investigate the clinical efficacy of endovascular interventional therapy for spontaneous isolated superior mesenteric artery dissection(SISMAD).Methods:The retrospective cohort study was conducted. The clinical data of 87 patients with SISMAD who were admitted to The First Affiliated Hospital of Army Medical University from March 2012 to March 2023 were collected. There were 80 males and 7 femals, aged 54(49,61)years. Of 87 patients, 55 cases undergoing conservative therapy were allocated into conservative therapy group and 32 cases under-going endovascular interventional therapy were allocated into endovascular interventional therapy group. Observation indicators: (1) clinical characteristics; (2) treatment; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were represented as absolute numbers and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) clinical characteristics. There were significant differences in the cases with symptoms, percentage of neutrophils between the conservative therapy group and the endovascular interventional therapy group ( P<0.05). There was no significant difference in the proportion of Yun classification between the two groups ( P>0.05). (2)Treatment. There were significant differences in the complete vascular remodeling, duration of hospital stay, and total expenses between the conservative therapy group and the endovascular interventional therapy group ( χ2=23.752, t=-4.213, -16.421, P<0.05). There were 34 patients in the conservative therapy group and 24 patients in the endovascular interventional therapy group with relieved abdominal pain, respectively, showing no significant difference between the two groups ( P>0.05). For symptomatic patients in the conservative therapy group, symptoms including abdominal pain, nausea, vomiting, diarrhea, hematochezia were relieved or disappeared, and no intestinal ischemia or rupture occurred. For patients in the endovascular interventional therapy group, 30 cases were implanted stents, the operation time was 115(86,155)minutes, volume of intraoperative blood loss was 5(5,10)mL, dose of contrast media was (200±51)mL. There were 23, 8 and 1 cases with the contrast medium as Iodoxanol, Ioprosamide, Iodohexanol, respectively. About the surgical methods, 14 patients received single bare stent implantation, 3 cases received bare stent-assisted coil embolization, 10 cases received multiple bare stent implantation, 3 cases received covered stent implantation, 2 cases received angiography alone. A total of 39 self-expandable bare metal stents and 3 self-expandable covered stents were implanted. The diameter and length of the stents were (6.5±1.0)mm and (69±23)mm, respectively. Two asymptomatic patients had failure in endovascular interventional therapy and underwent superior mesenteric artery angiography. For the endovascular interventional therapy group, 92.3%(24/26) of patients were relieved abdominal pain and 2 patients with abdominal pain were improved after symptomatic treatment. (3) Follow-up. All the 87 patients were followed up for 12(4,24)months, without recurrent abdominal pain or secondary intervention. During the follow-up, 82 patients underwent computed tomography angiography or ultrasonography, and 5 patients had no available results. There was no SISMAD related death or superior mesenteric artery rupture. Eight patients in the conservative therapy group achieved complete vascular remodeling, versus 21 cases in the endovascular interventional therapy group, showing a significant difference between the two groups ( χ2=23.752, P<0.05). Conclusions:Compared with conservative therapy, patients undergoing endovascular interventional therapy for SISMAD has loner hospital stay, higher total costs, higher complete vascular remodeling rate. There is no recurrent abdominal pain in two methods.

Heart activity is highly dependent on adenosine triphosphate (ATP) produced via mitochondrial oxidative phosphorylation. Traditional therapeutics has developed drugs by repairing damaged mitochondrial DNA, reducing mitochondrial reactive oxygen species (ROS) production, and accelerating the degradation of damaged mitochondria and recycle. In recent years, however, mitochondrial replacement therapy has taken a different strategy, and has entered the clinical trial stage. This review will summarize the research progress of cardiovascular drugs targeting mitochondria and mitochondrial replacement therapy to provide a new perspective for addressing some relevant endemic diseases in China.

Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate analysis was conducted using the t test or chi-square test based on data excluding missing data of clinico-pathological and surgical data. Multivariate analysis was conducted using the Logistic regression model based on factors with P<0.20 in univariate analysis. Results: There were 2 089 patients screened for eligibility, including 1 512 males, 576 females and 1 without sex information, aged (62±11)years. The body mass index (BMI) was (23±3)kg/m². (1) The incidence of POPF after radical gastrectomy: the total incidence rate of POPF in the 2 089 patients was 20.728%(433/2 089). The incidence rates of biochemical fistula, grade B pancreatic fistula, and grade C pancreatic fistula were 19.627%(410/2 089), 1.101%(23/2 089), 0, respectively. (2) Treatment of grade B POPF after radical gastrectomy: 2 of 23 patients with grade B POPF after radical gastrectomy had drainage tube placed for more than 21 days and received anti-infective therapy. Four of 23 patients with grade B POPF after radical gastrectomy had ascites detected by imaging examination, of which 2 received peritoneal drainage guided by ultrasound, 1 received failed puncture drainage, 1 received no puncture drainage, and they were given anti-infective therapy. Eleven of 23 patients with grade B POPF after radical gastrectomy had no ascites detected by imaging examinations, and they were given anti-infective therapy and inhibitors of pancreas secretion for clinical manifestation as fever or elevated white blood cells. Six patients with no typical clinical manifestations were given somatostatin to inhibite pancreas secretion and prolonged duration of abdominal drainage tube placement (with a median time of 7 days). All the 23 patients recovered well after treatment, without reoperation. (3) Analysis of clinicopathological data: for the 2 089 patients, BMI, cases with or without neoadjuvant therapy were (23±3)kg/m^2, 1 487, 160 of patients without pancreatic fistula, (23±3)kg/m^2, 386, 22 of patients with biochemical fistula, and (24±3)kg/m^2, 22, 1 of patents with grade B pancreatic fistula, showing significant differences between the three groups (F=5.787, χ²=8.269, P<0.05). (4) Analysis of surgical data: for the 2 089 patients, cases with open surgery, laparoscopic assisted surgery, totally laparoscopic surgery (surgical method), cases with D₁ lymph lode dissection, D₂ lymph lode dissection, and other lymph lode dissection (range of lymph lode dissection), cases with no omentectomy, partial omentectomy, and total omentectomy (range of omentectomy), cases with no usage of energy facility, usage of CUSA, LigaSure, LigaSure+ CUSA as energy facility, cases with or without biological glue, the number of lymph node dissection were 737, 624, 292, 24, 1 580, 51, 418, 834, 381, 63, 1 530, 23, 16, 1 431, 201, 33±14 of patients without pancreatic fistula, 146, 189, 74, 11, 389, 9, 110, 171, 128, 35, 359, 6, 9, 378, 31, 31±14 of patients with biochemical fistula, and 14, 5, 4, 0, 20, 3, 6, 13, 4, 2, 18, 1, 2, 22, 1, 37±16 of patients with grade B pancreatic fistula, showing significant differences between the three groups (χ²=15.578, 9.397, 15.023, 28.245, 8.359, F=4.945, P<0.05). (5) Risk factors for grade B POPF after radical gastrectomy: results of univariate analysis showed that usage of energy facility was a related factor for grade B POPF after radical gastrectomy (χ²=9.914, P<0.05). Results of multivariate analysis showed that laparoscopic assisted surgery, combined evisceration, application of LigaSure + CUSA, the number of lymph lode dissection were independent factors for for grade B POPF after radical gastrectomy (odds ratio=0.168, 3.922, 9.250, 1.030, 95% confidence interval: 0.036-0.789, 1.031-14.919, 1.036-82.602, 1.001-1.059, P<0.05). Conclusions The incidence of grade B POPF after radical gastrectomy is relatively low. Laparoscopic assisted surgery, combined evisceration, application of LigaSure + CUSA, and the number of lymph lode dissection are independent risk factors for grade B POPF.

Objective To explore the clinical efficacy of Da Vinci robot-assisted iliofemoral vein bypass grafting.Methods The retrospective descriptive study was conducted.The clinical data of one 66-year-old male patient who underwent Da Vinci robot-assisted iliofemoral vein bypass grafting in the First Affiliated Hospital of Army Military Medical University in March 2019 were collected.The patient was failed to recanalize iliofemoral vein stent thrombosis by endovascular measures and underwent Da Vinci robot-assisted iliofemoral vein bypass grafting after balloon occlusion preset in the common iliac vein.Observation indicators:(1) intra-and postoperative situations;(2) follow-up and survival situations.Follow-up using outpatient examination was performed to detect the patient's postoperative survival and swelling reduction of affected extremity up to April 2019.Results (1) Intra-and post-operative situations:the patient underwent Da Vinci robot-assisted iliofemoral vein bypass grafting successfully.The operation time of balloon occlusion preset by digital subtraction angiography was 35 minutes.The operation time of Da Vinci robot-assisted iliofemoral vein bypass grafting was 502 minutes (50 minutes of exposure time of femoral vein,80 minutes of exposure time of iliac vein,40 minutes of great saphenous vein harvesting time,70 minutes of end to side anastomosis between autogenous great saphenous vein and femoral vein,10 minutes of subcutaneous tunnel construction,90 minutes of end to side anastomosis between autogenous great saphenous vein and iliac vein,60 minutes of suturing except vessel closure,102 minutes of preparation time,check and washing time).The volume of intraoperative blood loss was 500 mL and no intraoperative complications occurred.The autogenous great saphenous vein graft was well filled and no bleeding was found at both proximal and distal anastomoses after iliofemoral vein bypass grafting.There were 4 abdominal Trocar holes including 2 of 1.2 cm and 2 of 0.8 cm.The incisional length of right groin and left great saphenous vein harvesting region was 5.0 cm and 15.0 cm,respectively.At the discharge time,the patient had swelling subsided partially at right lower extremity and skin tesion reduced significantly compared with the admission.The perimeters at 15 cm above right knee joint and left knee joint were 53.5 cm and 48.0 cm.The maximum perimeters of right calf and left calf were 41.0 cm and 38.0 cm.No postoperative complications occurred.Duration of hospital stay after surgery was 3 days.(2) Follow-up and survival situations:the patient was followed up for 1 month,with good survival.The patient had swelling subsided of affected extremity.The perimeters at 15 cm above right and left knee joint were 52.0 cm and 48.0 cm.The maximum perimeters of right calf and left calf were 40.0 cm and 38.0 cm.Conclusion The Da Vinci robot-assisted iliofemoral vein bypass grafting is safe and feasible,with good short-term outcomes.

Objective: To analyze the pathological features and their influence on the clinical outcome of non-nasopharyngeal EBV-associated carcinomas. Methods: One hundred and twenty cases of non-nasopharyngeal EBV-associated carcinoma confirmed by in situ hybridization were identified at Zhejiang Cancer Hospital from January 1, 2006 to May 1, 2018, and the clinicopathological data were collected and analyzed using Kaplan-Meier survival analysis, Cox univariate and multivariate analysis. Results: One hundred and twenty cases were involved in the study; the male to female ratio was 1∶1; patients′ age range was 24 to 89 years (median 50 years). The primary sites were large parotid glands (62 cases), lung(26 cases), stomach(15 cases), and others (oral, oropharynx, larynx, cervix, liver; totally 17cases). Non-nasopharyngeal EBV-associated cancer could be divided into two histological types according to the amount of interstitial lymphocytes: type Ⅰ was "lymphoepithelial-like carcinoma" and rich in stromal lymphocytes; type Ⅱ lacked lymphocytic infiltration. Ninety-eight primary tumor samples could be classified morphologically: 43 cases were as type Ⅰ and 55 cases as typeⅡ; the distribution of type Ⅰ was 57.4% (27/47) in large parotid glands, 20.8% (5/24) in lung, 4/13 in stomach, and 7/14 in other sites. Complete treatment and survival data were obtained for 114 patients. According to the TNM staging criteria of WHO, 52 patients were at early stages (Ⅰ-Ⅱ) and 62 were at advanced stages (Ⅲ-Ⅳ); 102 patients underwent surgery. Seventy-four patients received adjuvant chemotherapy before or after surgery, and 52 patients received local radiotherapy. Kaplan-Meier survival analysis showed that patients with type Ⅱ EBV-associated carcinoma had a worse prognosis than patients with type Ⅰtumors (P=0.010 2). In addition, vascular invasion(P=0.021 8),neural recidivism(P=0.000 1),advanced stage(P=0.017 1),lymph node metastasis (P=0.005 0) and chemotherapy (P=0.013 2) were poor prognostic factors; female patients had better survival than male (P=0.028 4). Cox multivariate regression analysis found that lymph node metastasis (95%CI: 1.489-13.830, P=0.007 6) and neural recidivism (95%CI: 1.228-6.544, P=0.014 7) were independent adverse prognostic factors. Cox multivariate regression analysis after stratification by site revealed that radiotherapy was a preferable prognostic factor for EBV-associated carcinoma of the large salivary glands (95%CI: 0.003-0.569, P=0.016 8). Conclusion EBV associated carcinoma can be divided into two types, for which type Ⅰ was with abundant interstitial lymphocytes and type Ⅱ was lack of interstitial lymphocytes. TypeⅡ EBV-associated carcinoma has a worse prognosis than type Ⅰ. Radiation therapy can prolong the survival time of patients with primary EBV-associated carcinoma of large salivary glands.

The mitochondrial quality control system maintains mitochondrial homeostasis mainly through protein degradation, vesicle transport, and mitophagy. Mitochondrial biosynthesis, dynamics, and calcium ion play key regulative roles in mitochondrial quality control. Under normal conditions, the mitochondrial quality control system can work well. In recent years, studies have found that mitochondrial dysfunction is closely associated with the occurrence of heart failure. In order to understand mitochondrial function, this paper reviews mitochondrial quality control methods, regulatory factors and their potential therapeutic applications in heart failure.

Objective To analyze the effects of Hual qi huang granules on children with mycoplasma pneumoniae pneumonia.Methods A randomized,multicenter parallel controlled clinical trial was carried out.A total of 3 000 cases of hospitalized children with mycoplasma pneumoniae pneumonia were selected.All of them were given treatment for mycoplasma pneumoniae pneumonia with macrolide antibiotics and symptomatic treatment.They were randomly divided into 2 groups:research group and control group.The children of research group were give oral Huai qi huang granules for three months.According to the classification of pneumonia,these two groups were divided into:lobar pneumonia research group,lobar pneumonia control group,lobular pneumonia research group,lobular pneumonia control group.The hospitalization duration of fever,length of hospital stay,the absorption area of lung inflammation and pneumonia severity sores were observed.The frequency of upper respiratory infections,bronchitis,pneumonia were observed in 3 months after discharge.Results 2 378 cases were investigated.The hospitalization duration of fever,length of hospital stay of research group were significantly shorter than that of in control group (P ＜ 0.001).The children with lobar pneumonia,2 weeks after treatment,the absorption of consolidation of the lobar pneumonia research group is significantly better than lobar pneumonia control group (P ＜0.001).After two weeks treatment,the pneumonia scores of lobar pneumonia research group is lower than lobar pneumonia control group (P ＜ 0.05).Followup of 3 months after hospital discharge,frequency of upper respiratory infection and bronchitis of research group,were significantly lower than that of control.In addition,appetite increased significantly in research group than control (P ＜ 0.001).There are 21 cases with drug associated adverse reactions (mild diarrhea),including 12 cases of research group,9 cases of control group,and there was no statistical significance (P ＞0.05).Conclusion Standard treatment combined with oral Huai qi huang granules in the treatment of mycoplasma pneumoniae pneumonia,can significantly shorten hospitalization duration of fever,length of hospital stay and reduce the severity score of pneumonia.Three months oral Huai qi huang granules can significant reduce the frequency of respiratory infections and bronchitis,also can increase patients appetite,and be safe.
