Objective:To assess the efficacy and safety of acupuncture compound anesthesia(ACA)for traditional thyroidectomy. Methods:Randomized controlled trials(RCTs)studying the use of ACA for traditional thyroidectomy were retrieved from PubMed,Excerpta Medica Database(EMBASE),Cochrane Library,Web of Science,China National Knowledge Infrastructure(CNKI),Chongqing VIP Database(CQVIP),Wanfang Academic Journal Full-text Database(Wanfang),and China Biology Medicine Disc(CBM)from inception to September 30,2021.Two investigators independently extracted data and assessed the risk of bias and quality of the studies.Anesthesia effectiveness was the primary outcome,while the secondary outcomes included various pain scales,vital signs,analgesic consumption,and adverse events.Review Manager 5.3 was used for meta-analysis.Weighted mean difference(WMD),standardized mean difference(SMD),and confidence interval(CI)were used for statistical descriptions. Results:A total of 16 papers were included,involving 1228 patients.Meta-analysis showed that anesthesia effectiveness was significantly improved after adding acupuncture as an adjunct[SMD=0.62,95%CI(0.40,0.83),P<0.0001,I2=36%].Besides,ACA can also moderate vital signs and reduce the feeling of pain[SMD=-1.61,95%CI(-2.61,-0.61),P<0.00001,I2=95%],analgesic consumption,and adverse events.Subgroup analysis of the electroacupuncture(EA)group further revealed that the effectiveness of low-frequency EA[WMD=0.43,95%CI(0.30,0.55),P<0.00001,I2=15%]and the entire operative stimulation of EA[WMD=0.55,95%CI(0.33,0.77),P<0.00001,I2=0%]was significantly better than high-frequency EA and short-time stimulation of EA during the operation.Further,no significant difference existed between conventional analgesia and acupuncture analgesia. Conclusion:ACA is beneficial to traditional thyroidectomy regarding efficacy and safety when acupuncture is applied as an adjunct.However,additional high-quality studies with larger sample sizes are needed to verify the findings.

[ ABSTRACT] AIM:To investigate the effect of atorvastatin on the development of heart failure after myocardial infarction and the association with sodium-calcium exchanger (NCX) expression.METHODS:The model of heart failure was established by ligation of the anterior descending coronary artery for 8 weeks.The rats were randomly divided into con-trol group, heart failure group, and atorvastatin group.Either atorvastatin (10 mg· kg-1· d-1) or vehicle was orally ad-ministered to the rats on the next day after the surgery .The left ventricular function and NCX expression were analyzed 8 weeks after ligation .Neonatal rat cardiomyocytes were cultured to investigate the effect of atorvastatin on the changes of cal -cium concentration induced by hypoxemia .RESULTS: A decrease in left ventricular diastolic dimension , an increase in left ventricular fractional shortening , and reductions of BNP level and NCX expression were observed in atorvastatin group . The hypoxemia-induced calcium overload in cultured cardiomyocytes was inhibited by atorvastatin , and it was inhibited by the inhibitor of NCX .CONCLUSION:Atorvastatin treatment improves cardiac function , which may be related to the ex-pression and function of sodium calcium exchanger in heart failure .

[Summary] Graves'ophthalmopathy ( GO) is the most common extrathyroidal manifestation of Graves disease ( GD) . It is an organ-specific autoimmune disorder. The estimated incidence of GO in the general population is 16 women and 3 men per 100,000 population every year. Approximately 3%-5% of patients with GO are exposed to the potential of losing their sight and requiring optimized medical intervention. For the clinicians it is helpful to assess the degree of activity and severity of GO;both are important in deciding whether a patient requires intervention and which type of intervention is indicated. These interventions include management of hyperthyroidism, measures to relieve local symptoms, immunosuppressive therapies for active moderate and severe GO, and finally rehabilitative surgery for inactive patients.

Background and purpose:Chemotherapy plays an important role in the treatment of breast carcinoma by inhibiting the tumor growth and inducing the apoptosis.MAPK transduction pathway is closely related to proliferation and apoptosis of varieties of tumor cells,inhibition of MAPK pathway may increase the efficiency and decrease the toxicity of chemotherapy.Our study was to investigate the effect of MEK inhibitor PD98059 in response of breast cancer cell lines to Epirubicin.Methods:Human breast cancer cell lines MCF-7 and MCF-7/ADR were used as cell models.Epirubicin(EADM),PD98059(inhibitor of MAPK Kinase-MEK),or EADM+PD98059 was added into the culture medium,the expression of MEK2 and p-ERK were measured by Western blot,the growth of the two cell lines were measured by MTT.Results:ERK activity was elevated in MCF-7 after the treatment of EADM,the cells were more sensitive to EADM if combined with PD98059,while in MCF-7/ADR,ERK activity kept unchanged after EADM treatment,and PD98059 has no effect on the sensitivity of cells to EADM.Conclusion:MAPK signal transduction may be activated in some cells treated by EADM,adding inhibitor of MAPK signal transduction could improve the sensitivity of the cells to EADM.

Background Pathologic myopia is one of the common blinding eye diseases.Recent research suggests that immune response participates in the pathogenesis of pathologic myopia,and inflammation is an important factor that influent immune status.Objective Present study was to observe the change of high sensitive C-reactive protein(hs-CRP) in serum in the patients with pathologic myopia and explore the role of inflammation in the development of pathologic myopia. Methods Serum hs-CRP was measured from 30 patients with pathologic myopia,30 patients with simple myopia and 30 normal controls with Nephelometric Turbidity in the OLYMPUS AU5400 automatic biochemical analyzer.Written informed consent was obmined from each subject before medical examination.Results The mean age was(30+10) years in pathologic myopia group,and(32+8)years in simple myopia group and(32+9)years in normal control group.The range of preoperative spherical equivalent refraction was (-6.00--22.00) D in pathologic myopia group,(-1.00--6.00) D in simple myopia group and(-1.00-+1.00) D in normal control group.The level of hs-CRP in serum was(3.68±1.15)mmol/L in the patients with pathologic myopia and was significantly higher than that of simple myopia group(1.99±0.68 mmol/L)and normal controls (2.11±O.66 mmol/L)(q=10.69,P＜0.01;q=9.91,P＜0.01),respectively.No significant correlation was found between hs-CRP level and myopic degrees in pathologic myopia group(R2=0.037,P＞0.05). Conclusion Hs-CRP may play rule in the inflammatory reaction during the pathogenesis of pathologic myopia.

Medullary thyroid cancer (MTC) is characterized hy the secretion of calcitonin that is derived from parafollicular cells.20％-25％ of MTC are hereditary.Compared with other types of thyroid cancer,MTC is prone to recurrence,metastasis,and younger onset age.RET gene germline mutation accounts for the hereditary MTC,and somatic mutation is responsible for part of sporadic cases.A good correlation between phenotype and genotype is reported.We present in this article a case of medullary thyroid cancer patient with genetic diagnosis and treatment as well as postoperative follow-up together with RET gene screening results in her family members in order to call attention to the diagnosis and treatment of MTC.

Objective To study the prognostic value of circumferential resection margin(CRM)status. Methods Specimens of 62 patients with rectal cancer,who underwent total mesorectal excision from December,2001 to June,2002,were examined using whole-mount sections.All patients were followed up for 4～60 months. Results Circumferential resection margin involvement(CRMI)was identified in 12 specimens.while only 4 of them were cancer positive in the resection margin.Analyzed by logistic regression test,the occurrence of CRMI was related to tumor differentiation [ P=0.015,Exp(B)=0.131]and lymph node metastases[P=0.013,Exp(B)=7.488 ],but not tumor distance to anal verge(P=0.246).The difference in local recurrence rate,overall recurrence rate,disease-free survival rate and overall survival rate between CRMI and that of CRM negative,were significant(P=0.002,0.000,0.000 and 0.003,respectively). Conclusions CRMI is an accurate prognostic factor of recurrence and postoperative survival,and its occurrence is mainly determined by biologic characteristics of the tumor.TME could decrease the incidence of CRMI.
