Objective To compare the therapeutic effect between routine shunting and selective shunting in patients with moderate and severe carotid artery stenosis undergoing carotid endarterectomy (CEA). Methods One hundred and ninety-two patients with moderate and severe carotid artery stenosis undergoing CEA were selected, and the patients were divided into control group (routine shunting) and observation group (selective shunting) according to the random digits table method with 96 cases each. The intraoperative carotid artery occlusion time and incidences of stroke event 30 d after operation were recorded. Results In the observation group, the rate of carotid artery shunting was 35.4% (34/96), among which the rate of carotid artery shunting in patients with contralateral severe carotid artery stenosis or occlusion was 8/13, the rate of carotid artery shunting in patients with unilateral carotid stenosis was 31.3% (26/83), and there was statistical difference (χ2 = 13.006, P<0.01). There was no statistical difference in intraoperative carotid artery occlusion time between control group and observation group ( t=2.091, P>0.05). In the observation group, the intraoperative carotid artery occlusion time in patients with carotid artery shunting was significantly shorter than that in patients without carotid artery shunting:(4.36 ± 0.48) min vs. (10.15 ± 0.91) min, and there was statistical difference (t=7.884, P<0.05). There was no statistical difference in the incidence of stroke event 30 d after operation between control group and observation group (χ2 = 1.189, P>0.05). Conclusions The selective shunting during CEA can reduce the incidence of postoperative stroke event in patients with carotid artery stenosis, and especially it can give a good clinical effect in the patients with contralateral severe carotid artery stenosis or occlusion.

Objective To investigate the dynamic changes of endothelial progenitor cells (EPCs) in peripheral blood of patients with hypertensive cerebral hemorrhage.Methods Flow cytometry was used to detect the dynamic changes of EPCs in 79 cases of hypertensive cerebral hemorrhages as the experimental group and 70 cases of normal healthy people as the control group.Results In the acute phase after hemorrhage (3 days),EPCs in experimental group [(51.3 ±9.3) × 103/ml,(52.0 ±6.3) × 103/ml,(53.1 ±9.3) × 103/ml] were significantly lower than the control group [(75.4 ± 15.6) × 103/ml] (P <0.05).However,after that the level of EPCs in experimental group [(110.9 ± 12.0) × 103/ml,(132.8 ± 11.8)× 103/ml,(115.3 ±9.9) × 103/ml] increased rapidly and was significantly higher than the control group (P <0.05),and approximately two weeks later it reduced to normal levels [(83.1 ±7.9) × 103/ml].Conclusions In patients with hypertensive cerebral hemorrhage,the levels of EPCs in peripheral blood were closely related with the disease and might become a prognostic marker.
3.Research Progress on regarding the torque control of upper anterior teeth with a lip appliance
Journal of Prevention and Treatment for Stomatological Diseases 2019;27(2):122-126
The normal torque angle of the maxillary anterior teeth is an important factor in the aesthetics and function of the anterior teeth, and torque control of the front teeth is an extremely important aspect of the correction process. At present, the normal torque angle of the front teeth is among the phase Ⅲ clinical test items recognized by the American orthodontic professional committee; consequently, good control of front teeth torque is of great significance to the aesthetics of the upper anterior teeth. In this paper, the influence of a lip appliance on the bad torque of upper anterior teeth and the associated methods of control are reviewed in detail. The advantages and disadvantages of various control methods for the anterior teeth and the significance of correct anterior teeth torque angle are summarized. The existing research results indicate that the torsion of a straight arch wire applied directly to individual teeth is too great, making it difficult to enter the groove. Although the bending of the arch wire overcomes these shortcomings, the procedure is cumbersome; it stimulates the soft tissue of the vestibular groove and increases the patient’s discomfort. The bending mechanism of the rocking chair is more complicated; it is greatly affected by the friction between the arch wire and the bracket and is not conducive to closing the tooth extraction gap using the sliding method. The portal auxiliary arch and the single bending torque are suitable for correcting the torque angle of a single tooth. Auxiliary arch torque can be used to correct the upright upper anterior teeth during the process of closing the extraction space and after adduction; therefore, this procedure is worth popularizing. However, the accuracy of orthodontic control of anterior teeth torque requires further study.

Background: Transjugular intrahepatic portasystemic shunt (TIPS) is widely used for reducing portal hypertension. Post-TIPS anticoagulant treatment is controversial because of lack of obligatory evidence. Aims: To systematically review the effect of anticoagulant treatment on patients with liver cirrhosis after TIPS. Methods: Randomized controlled trials (RCTs) of liver cirrhosis patients after TIPS with anticoagulant treatment (anticoagulant treatment group) or without anticoagulant treatment/placebo (control group) were retrieved from PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang, CBM and VIP databases in March 2020. Meta-analysis was conducted by RevMan 5.3. Results: Three RCTs involving 157 liver cirrhosis patients were enrolled. These studies mainly reported the effects of anticoagulant treatment on gastrointestinal rebleeding, stent patency, mortality and incidence of hepatic encephalopathy (HE). Meta-analysis revealed that no significant differences in total gastrointestinal bleeding rate (OR=1.04, 95% CI: 0.25-4.38, P=0.96), variceal bleeding rate (OR=1.04, 95% CI: 0.14-7.68, P=0.97), stent stenosis (OR=1.88, 95% CI: 0.73-4.79, P=0.19), occlusion (OR=0.07, 95% CI: 0.00-1.44, P=0.09), shunt dysfunction (OR=0.67, 95% CI: 0.10-4.29, P=0.67), mortality (OR=2.12, 95% CI: 0.06-72.77, P=0.68) and incidence of HE (OR=1.18, 95% CI: 0.45-3.06, P=0.74) were found between anticoagulant treatment group and control group. Conclusions: Post-TIPS anticoagulant treatment is safe and without increasing the rate of gastrointestinal rebleeding, mortality and incidence of HE. However, anticoagulant treatment does not further improve the stent patency. Therefore, anticoagulant treatment appears to be unnecessary in patients with liver cirrhosis after TIPS.

ObjectiveTo investigate the gastroscopic manifestations of gastric mucosa in portal hypertensive gastropathy (PHG) and the association of PHG with gastroesophageal varices, ulcers, and liver cirrhosis complications. MethodsA retrospective analysis was performed for the clinical data of 867 patients with liver cirrhosis who were treated in Daping Hospital of Army Medical University from August 2012 to June 2018, and the incidence rates of gastroesophageal varices, PHG, and ulcers were recorded. Meanwhile, the data of spontaneous bacterial peritonitis (SBP), hepatic encephalopathy (HE), and hepatocellular carcinoma (HCC) were collected. The chi-square test was used for comparison of categorical data between groups, and a Spearman correlation analysis was also performed. ResultsThe incidence rate of PHG in the patients with liver cirrhosis reached 66.2% (574/867), and gastric mucosa abnormalities in mild PHG were mainly red-spot lesions (68.6%) and snakeskin (56.8%), while diffuse erythema (76.5%) was the main gastric mucosa abnormality in severe PHG. There was a significant difference in the incidence rate of PHG between the patients with different severities of esophageal varices (χ2=304712, P<0.05), and the severity of PHG increased with the aggravation of esophageal varices (r=0.515, P<0.05). There was a significant difference in the incidence rate of PHG between the patients with different severities of gastric varices (χ2=81.004, P<0.05), and the severity of PHG was positively correlated with that of gastric varices (r=0.292, P<0.05). There was a significant difference in the incidence rate of PHG between the patients with varices at different locations (χ2=41.361, P<0.05); the patients with gastric varices alone had the lowest incidence rate of PHG (34.8%) and only had mild PHG, and those with gastroesophageal varices had the highest incidence rate of PHG (85.6%). Among the patients without PHG, 71 (24.2%) were hospitalized due to hematemesis and/or tarry stool, and among the 574 patients with PHG, 316 (55.1%) were hospitalized, and there was a significant difference between the two groups (χ2=74562, P<0.05). ConclusionPatients with different severities of PHG have different features of gastric mucosa abnormalities. The development and severity of PHG are closely associated with the severity of gastroesophageal varices and are important causes of gastrointestinal bleeding in liver cirrhosis. PHG should be treated and prevented to reduce the risk and complications of gastrointestinal bleeding.

Objective To explore the expression of Fas ligan d (FasL) protein in human non-small cell lung cancer (NSCLC) and its clinic al significance. Methods Expression of FasL protein was detecte d by immunohistochemical method in 32 resected tumors of NSCLC. Results FasL protein was detected in all of these 32 resected tumors with variant pos itive expression levels ranging from 3.0% to 98.7% [mean (62.0±32.0)%]. T here wa s significant difference between the tumors of different pathological types no s ignificant difference was found between the tumors of different differentiation nor among the tumors of different pTNM stages (P>0.05). Conclusion The results indicated that NSCLC can counterattack the immune cells of t he body and may be the molecular basis for the easily metastasis of adenocarcino ma to in the early stage.
7.Consent for blood transfusion: How is it understood by transfusion candidates
Chinese Journal of Blood Transfusion 2021;34(9):939-942
【Objective】 To assess the sufficient information got by the informed transfusion recipients from the consents for blood transfusion and to explore the influencing factors, so as to provide scientific evidences for patients to comprehend the consent better. 【Methods】 A cohort study using questionnaire was conducted among 198 patients who received red blood cell transfusion from April 2019 to June 2019 in a tertiary hospital. 18 options were investigated, including basic information of patients, recall of the informed consent process performed by physicians and how well they comprehend the information. SPSS 23.0 statistical software was used for data statistical processing. 【Results】 All 198 questionnaires were returned and valid (100%, 198/198). The score of 198 informed transfusion recipients was 2~9 (5.293±1.549), and the score of Internal Medicine and Surgical transfusion patients was 6.07±1.77 vs 6.07±1.77 (P<0.05). Univariate comparative analysis showed that the clinical department, age, education background, instructions, including its time and identity of instructors, before transfusion were the variables that affected the comprehension of informed patients (P<0.05). Linear regression analysis indicated that the clinical department, pre-transfusion instruction and its time were independent influencing factors on the comprehension(P<0.05). The top 3 poorly-understood items included auto-transfusion, alternative transfusion therapy and 1-year donation deferral after blood transfusion. 【Conclusion】 More efforts are needed to help transfusion candidates to comprehend consent for blood transfusion better since their knowledge varied with clinical departments. Physicians′ transfusion knowledge and communication skills also need to be enhanced to provide targeted and multi-form informing methods.

Objective: To investigate the feasibility of transumbilical single-incision plus one port (SIPOP) robotic total mesorectal excision. Methods: Clinical data of a 70-year-old male patient with BMI 22.1 kg/m(2) who successfully underwent transumbilical single-incision plus 1 port robotic total mesorectal resection of upper rectal cancer at the General Surgery Department of Daping Hospital of Army Military Medical University on September 18, 2019 were retrospectively analyzed. Preoperative colonoscopy revealed that the distance of upper rectal cancer to anal edge was 14 cm, and the tumor size was 2.5 cm×1.5 cm×1 cm. Pathological result confirmed rectal moderately differentiated adenocarcinoma. The preoperative abdominal CT showed thickened bowel-wall of upper rectum and the blurred perirectal fat, suggesting tumor infiltration. Results: The operation was successful. There were no conversion to laparotomy or abdominal auxiliary incision, and the mesorectum of the specimen was intact. The operation time was 165 minutes, the blood loss was about 20 ml, and there were no complications such as injury to peripheral organs. Postoperative pathology showed ulcerative moderately differentiated adenocarcinoma of the upper rectum with TNM stage IVA (T4N2b). The postoperative recovery was smooth. Patient ambulated on the 1st day, the catheter was removed on the 7th day, and discharged from the hospital on the 8th day. Conclusion: The transumbilical SIPOP robotic total mesorectal excision is safe, effective and feasible.

【Objective】 To pilot an informed consent audit system for clinical transfusion in a large tertiary hospital, so as to provide evidence and recommendations to improve the consent system. 【Methods】 A report table containing key items of transfusion informed consent such as transfusion risk, transfusion benefit and alternative treatment was developed in compliance with the national guidelines and regulations, and issued to a total of 206 patients with records on red blood cell transfusion from April 1 to June 30, 2019 in a tertiary hospital. 【Results】 The audit results showed that 98.06% (202/206) of transfusion informed consents were signed by patients, but only 65.05% (134/206) were signed by doctors. 31.07% did not record the reasons for transfusion, and 46.6% did not record the transfusion plan. 99.31% of the doctors participated in the audit claimed that the patients were informed of the risk of blood transfusion, but only 79.8% (158/198) patients recalled that the doctors mentioned the risk. Although 80.5% (116/198) of the patients were informed of alternative treatment, only 28.79% (57/198) recalled being told about alternative treatment. Allogeneic blood transfusion was the most frequently choice for patients recommended by doctors, accounting for 98.61% (142/144). However, only 48.99% (97/198) of patients could recall allogeneic blood transfusion. 80.5% of the patients recalled being informed of alternative treatment plans, and only 28.79% of the patients recalled being offered alternative treatment plans. Only 43.43% of the patients considered themselves as the main participants in decision-making of blood transfusion. In terms of training, 82.64% (119/144) doctors described having attended training programs. 【Conclusion】 The written consents for blood transfusion in our hospital were not well recorded. Patients received less information of blood transfusion informed by the doctors and did not fully participant in the decision-making of blood transfusion. There is a gap between the practice and the current national guidelines and regulations. The audit results indicated that it is necessary to further strengthen the professional knowledge of clinicians and communication skills between the doctors and patients. This audit results in this study will provide recommendations for further transfusion informed consent audit and continuous improvement of clinical transfusion informed consent practice in China in the future.
