OBJECTIVE: To compare the clinical efficacy of acupuncture with Neiguan (PC6)-to-Waiguan (TE5) and esmolol on hemodynamics during anesthesia induction and postoperative nausea and vomiting. METHODS: A total of 100 patients undergoing elective laparoscopic hernia repair or gynecological surgery under general anesthesia were randomly divided into an acupuncture group (50 cases, 3 cases were eliminated) and an esmolol group (50 cases, 2 cases were eliminated). In the acupuncture group, before anesthesia induction, patients were applied to acupuncture with Neiguan (PC6)-to-Waiguan (TE5), and the needles were retained for 15 min on the right side and 30 min on the left side. Patients in the esmolol group were intravenously injected with 20 mg esmolol hydrochloride injection 5 min before anesthesia induction. The systolic blood pressure (SBP) and heart rate (HR) of the two groups were recorded at 5 min after entering the operating room (T₀), before anesthesia induction (T₁), after anesthesia induction (T₂), before tracheal intubation (T₃) and 1 min after tracheal intubation (T₄). The visual analogue scale (VAS) scores of pain and the incidence of nausea and vomiting in the two groups were observed at the time of entering postanesthesia care unit (PACU) (T₅), leaving PACU (T₆), 6 h after operation (T₇) and 24 h after operation (T₈). The dosage of anesthesia-related drugs in the two groups was counted. RESULTS: The SBP and HR of the two groups at T₂, T₃ and T₄ were lower than those at T₁ (P<0.05). SBP and HR at T₃ in the acupuncture group were higher than those in the esmolol group (P<0.05). Compared with the esmolol group, in the acupuncture group, the VAS scores of pain at T₆ and T₇ were decreased (P<0.05), the incidence of nausea and vomiting at T₇ and T₈ and the nausea and vomiting visual analogue scale (NVAS) scores were decreased (P<0.05). Compared with the esmolol group, the dosage of propofol in the acupuncture group was decreased (P<0.05). CONCLUSION Acupuncture with Neiguan (PC6)-to-Waiguan (TE5) can relieve hemodynamic fluctuations during anesthesia induction, reduce postoperative pain and nausea and vomiting, and reduce the dosage of propofol. The curative effect is better than that of esmolol.

Objective To investigate the current status of self-management in adult patients with epilepsy and re-lated influencing factors.Methods Epilepsy Self-Management Scale(ESMS)was used to evaluate the self-management abilities of 180 patients with epilepsy in a district of Shanghai,China,and the impact of related factors on the self-management abilities of patients was analyzed,including demographic factors(sex,age,marital status,and educational level,etc.)and clinical factors(age of onset,course of disease,seizure frequency,and types of medication,etc.).Results The total score of self-management was(102.62±6.11)points for the patients with epilepsy.There was a sig-nificant difference in self-management score between the patients with different occupations(F=2.950,P<0.05)and be-tween the patients with different family incomes(F=7.298,P<0.05).The patients who missed fewer doses of antiepilep-tic drugs had a higher self-management score(F=35.948,P<0.05),and there was a significant difference in self-management score between the patients with different follow-up frequencies(F=15.619,P<0.05).Medication manage-ment showed the strongest correlation with safety management(r=0.435,P<0.05),while safety management showed the lowest correlation with seizure management score(r=-0.152,P<0.05).The multiple linear regression analysis showed that medication compliance and follow-up frequency in specialized care were influencing factors for total self-management score.Conclusion The patients with epilepsy have poor self-management abilities,and improving employment rate,in-creasing family income,enhancing medication compliance,and increasing follow-up frequency in specialized care have a certain clinical significance in improving the self-management abilities of patients.

Objective:To explore the metabolic basis and related molecular mechanism of oral squamous cell carcinoma(OSCC)path-ogenesis.Methods:20 Chinese hamsters were divided into 2 groups(n=10).OSCC models were induced by dimethylbenzanthracene(DMBA)in 10 of the animals and the other 10 were used as the controls.LC-MS chromatography-mass spectrometry was used to iden-tify the metabolites in the buccal pouch,and multidimensional statistical analysis of the metabolites was performed with the orthogonal partial least squares discriminant analysis model.Variable Importance for the Projection(VIP)＞1 and P＜0.05 were used as the criteria to screen the differential metabolites between the 2 groups.KEGG pathway annotation and enrichment analysis for the metabolites were performed to screen the significantly differential pathways.Results:The hamster cheek pouches painted with 0.5％DMBA for 18 weeks were diffused with leukoplakia and loaded obvious papillary protrusions,which were diagnosed as OSCC by pathological examination.Lipids and lipid-like molecules were the main differential metabolites.Reprogramming of unsaturated fatty acid biosynthesis,cholesterol accumulation,enhanced catabolism of tryptophan,up-regulation of aspartate,increased synthesis of pyrimidine and purine,etc.were important metabolic features in the occurrence and development of OSCC.Conclusion:Molecular intervention targeting the related met-abolic pathways is expected to inhibit OSCC pathogenesis and progression.

BACKGROUND:In the treatment of skin trauma with active repair,tissue engineering techniques are needed to generate new tissue to replace necrotic tissue.Skin scaffolds have a good application prospect in the field of wound repair.Skin scaffolds need to present three-dimensional porous structures with certain mechanical strength to meet the needs of cell proliferation and division.However,the mechanical strength of the currently used gelatin-based biomaterials is weak and cannot meet the requirements of the use of skin scaffolds. OBJECTIVE:To study the 3D printing process used in the preparation of tissue engineering skin scaffolds by gelatin/oxidized nanocellulose composites,and focus on the relationship between the porosity and mechanical strength of the scaffolds prepared under different process parameters. METHODS:Oxidized nanocellulose whiskers at 10%concentration were extracted from Humulus scandens and then compounded with 5%gelatin to obtain gelatin/oxidized nanocellulose composites.The elastic modulus of gelatin and gelatin/oxidized nanocellulose composite was determined.Skin scaffolds were prepared by 3D printing extrusion molding using gelatin/oxidized nanocellulose composite as the base material.Mechanical and rheological properties of the composite were tested to determine extrusion molding parameters(filling gap 1.5-2.5 mm,uniform distribution of 0.1 mm;air pressure of 160-200 kPa),and the skin scaffold with a three-dimensional porous structure was prepared.The compressive performance of the skin scaffold was tested and compared with the finite element analysis results.The relationship between the filling gap and the porosity and mechanical strength of the scaffold was demonstrated. RESULTS AND CONCLUSION:(1)The elastic modulus of 5%gelatin was increased by 8.84 times by adding 10%oxidized nanocellulose whisker.A gel filament with a diameter of 1 mm was obtained by extrusion at the air pressure of 160 kPa.When the filling gap increased from 1.5 mm to 2.5 mm,the theoretical porosity of the scaffold increased from 33%to 60%,but the compressive strength decreased from 230 000 Pa to 95 000 Pa.(2)These findings showed that the skin scaffold with theoretical porosity of 50%and elastic modulus of 160 000 Pa was prepared by using 2 mm filling gap.The scaffold had a clear three-dimensional porous structure.

【Objective】 To investigate the clinical characteristics and antibody distribution as well as evaluate the transfusion efficacy in unexpected antibody positive patients. 【Methods】 A total of 12 235 patients from January 1, 2022 to March 31, 2023 who hospitalized in our hospital and applied for blood transfusion were selected, and those with unexpected antibody were included. The clinical data, including gender, age, diagnosis, blood type, history of transfusion and pregnancy were collected for antibody distribution analysis. Patients who received transfusion were grouped according to the DAT results and the components of red blood cells transfused, and the Hb values of each group before and after transfusion were compared. 【Results】 Among12 235 patients, 118 were positive for antibody screening, with a prevalence of 0.96%. The antibodies from Rh system were the most common (27.43%, 48/175), followed by MNS system (8.57%, 15/175) and Lewis system (6.29%, 11/175), mainly anti-E (18.29%, 32/175), anti-M (8.00%, 14/175) and anti-Le^a (5.71%, 10/175). In addition, 62 transfused patients were divided into group A with suspended red blood cell transfusion and group B with washed red blood cell transfusion for positive DAT, and group C for negative DAT. Hb values (g/L) pre- and post-transfusion were 59.19±15.67 vs 77.52±15.09 in group A, 56.35±14.08 vs 74.44±15.63 in group B, 56.00±12.06 vs 75.00±4.73 in group C, respectively. The Hb values of post-transfusion for three groups were all higher than those of pre-transfusion (P<0.05). 【Conclusion】 Anti-E from Rh system is the most common antibody in patients with unexpected antibody. Appropriate red blood cells transfusion with Hb increases by an average of 6-7 g/L per 1 U of red blood cells indicating good transfusion efficacy. For positive DAT patients, transfusion of suspended red blood cell is feasible.

【Objective】 To retrospectively analyze the characteristics of blood transfusion compatibility detection in patients with delayed serologic transfusion reaction ( DSTR), in order to provide reference for safe and effective blood transfusion in clinical practice. 【Methods】 From April 2020 to July 2021, 6 samples of patients who applied for blood type identification, unexpected antibody screening and transfusion from the Third People′s Hospital of Chengdu or People′s Hospital of Sichuan Province were collected. Microcolumn method was used for identification of ABO and RhD blood type of patients; unexpected antibody screening, blood cross-match, antibody identification and direct anti-human globulin tests were also conducted. The sensitizing antibodies on the surface of red blood cells were identified by acid release solution, and the antigen-antibody reaction was enhanced by polyethylene glycol. The patients′ own red blood cells and input red blood cells were separated by capillary high-speed centrifugation, and the surface antigens of red blood cells were detected by serological method. Meanwhile,the characteristics of patients before and after transfusing antigen-positive red blood cells were summarized. 【Results】 Anti-E was detected in the plasma of patients 1 and 2, and anti-c,-E were detected in the red blood cell release solution, while anti-C, anti-E, anti-JKa and anti-Fyb were detected in the plasma and red blood cell release solution of patients 3, 4, 5 and 6, respectively. After capillary high-speed centrifugation, antigen-positive red blood cells were detected in the distal end of the blood samples of 6 patients. 【Conclusion】 For patients with multiple blood transfusions and a recent history of blood transfusion, when newly emerging erythrocyte antibodies with clinically significance, direct anti-human globulin test(+) or erythrocyte antibody screening(+) are detected, and the patient has no clinical symptoms of hemolysis, it should be suspected as DSTR occurrence, and the transfusion reaction investigation procedure should be initiated in time.

ObjectiveThis paper analyzed the punishment situation of unlicensed medical practice in recent 7 years in Jinshan District of Shanghai， then suggested the countermeasures to prevent and combat unlicensed medical practice in the future. MethodsA total of 190 cases of unlicensed medical practice from 2016 to 2022 were investigated. The basic situation of the punishment，legal basis，subject distribution，clue source and individual characteristics were analyzed. ResultsThe case-filing number of unlicensed medical practice showed a decreasing trend，but the amount of fines increased obviously. The clues of investigation and punishment of unlicensed medicine practice were mainly found by inspection（32.11%） and transferred from other departments（28.42%）， while the number of complaints and clues reported from grassroots increased year by year. Medical and dental were the two major unlicensed practice，accounting for 35.79% and 33.16%， respectively. In addition， unlicensed medical cosmetology practice was increasing year by year. 78.62% of the unlicensed medical practioners are immigrants， 62.76% of them aged between 31 and 50 years old， among them 70.34% are men， and 62.76% of them have a fixed place. ConclusionThough the prevention and crack-down on unlicensed medical practice has achieved significant achievements，it is still necessary to enhance the responsibility of local administration，strengthen the inspection，investigate and deal with cases jointly by multiple departments，and implement the comprehensive supervision mechanism of the health care industry.

Bladder wall cysts are clinically rare, and even rarer when occurring simultaneously with bladder cancer. In this paper, we reported a patient with bladder cancer combined with a bladder wall cyst, who was admitted due to the urinary frequency and gross hematuria. Preoperative ultrasound and CT examination revealed a tumor in the left and right anterior wall of the bladder respectively. The cystoscopy showed low-grade uroepithelial carcinoma of the left wall of the bladder and occupancy of the right anterior wall of the bladder. Transurethral plasma enucleation of bladder tumor and suprapubic small incision partial cystectomy was performed. Postoperative pathology confirmed high-grade uroepithelial carcinoma of the left wall of the bladder and cyst of the right wall. There was no recurrence or metastasis 15 months after surgery.

Objective:To explore the status and influencing factors of physical activity, sedentary behavior in middle-aged and elderly patients with stable coronary heart disease, and to provide reference for clinical medical staff to formulate targeted intervention measures.Methods:This was a cross-sectional survey. From March to June 2022, a convenience sampling was used to select 378 middle-aged and elderly patients with stable coronary heart disease in the ward and clinic of Department of Cardiology, Jinshan Hospital, Fudan University. The general information questionnaire, the International Physical Activity Questionnaire, the Adult Sedentary Behavior Questionnaire, the Tampa Scale for Kinesiophobia Heart, the Self-efficacy for Chronic Disease Scale and the Social Support Rating Scale were used for investigation.Results:The total metabolic equivalent of physical activity and sedentary time in middle-aged and elderly patients with stable coronary heart disease were 31.40 (21.73, 49.67) MET-h/w and 8(7, 9) h/d respectively. The 39.7% (150/378) patients reached physical activity guidelines recommendations and 61.4% (232/378) patients had a sedentary time ≥ 8 h/d. The 19.0% (72/378) patients were identified as physically active/low sedentary group, 20.6% (78/378) patients were identified as physically active/high sedentary group, 19.6% (74/378) patients were in physically inactive/low sedentary group and 40.7% (154/378) patients were in physically inactive/high sedentary group. The stepwise multiple regression analysis showed that sedentary behavior, working status, kinesiophobia, objective support and disease duration had significant impacts on physical activity ( t values were -9.81-2.67, all P<0.05). The influencing factors of sedentary behavior were physical activity, objective support, support utilization, gender, educational level and kinesiophobia ( t values were -10.77-4.63, all P<0.05). Conclusions:The status of physical activity, sedentary behavior in middle-aged and elderly patients with stable coronary heart disease is not good. Medical staff should intervene corresponding influencing factors to reduce the risk of physical inactivity and high sedentary behavior in this group.
