Objective To compare the curative effect of laparoscopic and laparotomic operation for elderly Chinese women with cervical cancer. Methods The randomized controlled trials (RCT) and case controlled trials (CCT) were collected by searches of WanFang database, CNKI, VIP, China Biology Medicine (CBM) , PubMed. Data were extracted from these trials and data analysis was performed by RevMan 5.2.9. Results There were no RCTs, however, a total of 10 CCTs met the inclusion criteria and had data extracted for this review. The baseline characteristics of the laparoscopic group were similar to those of the laparotomic group. Comparing to laparotomic group, the laparoscopic group have longer operation time (MD =32.60, 95%CI: 5.65~59.55, P = 0.020), less amount of bleeding (MD = -94.01, 95%CI: -130.65 ~ -57.37, P = 0.000), smaller number of lymph node dissection(MD = 1.69, 95%CI: 0.67 ~ 2.72, P = 0.001), earlier anus exhaustion (MD=-17.09, 95%CI: -21.19 ~ -12.98, P = 0.000) and shorter hospital stays (MD = -4.30, 95%CI: -5.57 ~ -3.02, P = 0.000). There was significant difference between the two groups. But there was no statistical significance in postoperative indwelling catheter time (MD = -0.67, 95%CI: -1.92 ~ 0.58, P = 0.290) and surgical complications incidence (OR=0.62, 95%CI: 0.27 ~ 1.42, P = 0.260) between the two groups. Conclusion Laparoscopic management has the advantages of less traumatic and recovered quickly, and did not increase the incidence of complications. Laparoscopic operation is an ideal procedure for elderly Chinese women with cervical carcinoma.

Objective To systematically evaluate the risk factors for ovarian metastasis of endometrial carcinoma(EC) to provide an evidence-based medicine basis for formulating the EC surgical mode and ovarian metastatic risk.Methods Studies about the risk factors for EC ovarian metastasis were retrieved by computer from the Pubmed,Embase,Cochrane Library,WanFang database,CNKI,China Biology Medicine(CBM) from Jan.1,1990 to Sep.1,2016.The quality evaluation of included literature was performed by using the Newcastle-Ottawa Scale(NOS).Results A total of 13 studies were included,involving 6 140 EC patients,of whom 344 cases(5.60％) had ovarian metastasis.The Meta analysis results showed that a total of 9 factors had statistical significance,which were deep myometrial infiltration(OR =0.28,95 ％ CI:0.21-0.39),cervical involvement (OR =0.27,95 ％ CI:0.16-0.45),lymph node involvement (OR =0.21,95 ％ CI:0.15-0.27),fallopian tube involvement (OR =0.05,95 ％ CI:0.02-0.10),non-endometrioid adenocarcinoma(OR=0.32,95％CI:0.24-0.43),low differentiation(OR=0.39,95％CI:0.31-0.50),positive ascites cytologic detection(OR=0.14,95％CI:0.09-0.20),high serum CA125 level(OR=0.12,95％CI:0.08-0.19) and lymphovascular cancer embolus(OR =0.34,95 ％ CI:0.23-0.50),the differences were statistically significant(P＜0.05).But the age,lesion location,lesion diameter and estrogenic receptor level had no statistical difference(P＞0.05).Conclusion Deep myometrial infiltration,cervical involvement,lymph node involvement,fallopian tube involvement,non-endometrioid adenocarcinoma,low differentiation and positive ascites cytologic detection,high CA125 level and lymphovascular cancer embolus are the risk factors for EC ovarian metastasis.

Purpose: This study aimed to investigate the changes in microRNA-130a (miR-130a) and its correlation with cardiotoxicity during epirubicin/cyclophosphamide followed by docetaxel plus trastuzumab (EC-D+T) adjuvant chemotherapy in human epidermal growth factor receptor-2-positive (HER2+) breast cancer patients. Methods: A total of 72 HER2+ breast cancer patients who underwent resection and were scheduled to receive EC-D+T adjuvant therapy were consecutively enrolled. The expression of miR-130a and cardiotoxicity (defined as any of the following situations: 1) absolute decline of left ventricular ejection fraction (LVEF) ≥ 10% and LVEF < 53%; 2) heart failure; 3) acute coronary artery syndromes; and 4) fatal arrhythmia) were assessed every 3 months throughout the 15-month EC-D+T treatment. Results: The accumulating cardiotoxicity rate was 12 (16.7%), of which the incidence of heart failure, acute coronary syndrome, life-threatening arrhythmias, ΔLVEF ≥ 10%, and LVEF < 53% was 0 (0.0%), 1 (1.4%), 0 (0.0%), and 12 (16.7%), respectively. Baseline miR-130a expression was negatively correlated with LVEF (%) and positively correlated with cardiac troponin I. The expression of miR-130a gradually increased in both cardiotoxicity and noncardiotoxicity patients during EC-D+T treatment, while the increment of miR-130a was more obvious in cardiotoxicity patients compared with non-cardiotoxicity patients. Further logistic regression and receiver operating characteristic curve analysis indicated that miR-130a was an independent predictive factor for increased cardiotoxicity risk. Conclusion MiR-130a increases constantly and predicts high cardiotoxicity risk during ECD+T adjuvant chemotherapy in HER2+ breast cancer patients.

Objective To explore the predictive value of serum homo sapiens microRNA(hsa-miR)-30c-5p expression in patients with type 2 diabetes mellitus(T2DM)for microvascular complications.Methods A total of 205 T2DM patients admitted to Bazhong Central Hospital from May 2021 to September 2022 were selected as the diabetes group,and the diabetes group was further divided into diabetes with combined group(n=124)and non combined group(n=81)according to the microvascular complications of the patients.In addition,205 healthy people who underwent physical examination during the same period were selected as the control group.The expression of hsa-miR-30c-5p in serum was detected by reverse transcription-polymerase chain reaction(RT-PCR)and compared.The factors affecting microvascular complications were analyzed using multivariate logistic regression analysis,and receiver operating characteristic(ROC)curves were plotted to predict the value of serum hsa-miR-30c-5p expression in predicting microvascular complications in T2DM patients.Results The expression of serum hsa-miR-30c-5p in the combined group(0.58±0.06)and the non-combined group(0.72±0.08)were lower than that in the control group(0.89±0.21),and the differences were significant(t=16.038,7.079,all P=0.001).The combined group was lower than the non-combined group,and the difference was significant(t=14.289,P=0.001).The course of diabetes[(OR(95％CI):3.873(2.976～4.770)],uric acid[(OR(95％CI):2.125(1.211～3.040)]and glycosylated hemoglobin[(OR(95％CI):2.680(1.745～3.616)]were independent risk factors for microvascular complications in T2DM patients(all P＜0.05),while the time within the target range of glucose[(OR(95％CI):0.491(0.135～0.846)]and serum hsa-miR-30c-5p[(OR(95％CI):0.532(2.976～4.770)]were protective factors for microvascular complications in T2DM patients(all P＜0.05).The sensitivity,specificity and area under the curve(95％CI)of serum hsa-mir-30c-5p expression in predicting microvascular complications in T2DM patients were 81.45％,85.19％and 0.802(0.741～0.854),respectively.Conclusion The expression of serum hsa-miR-30c-5p in patients with T2DM is abnormally reduced,and serum hsa-miR-30c-5p is a protective factor for microvascular complications in patients with T2DM.It may have a certain predictive value for microvascular complications in patients with T2DM.

Objective:To investigate the application of patient-based real-time quality control (PBRTQC) using exponentially weighted moving average (EWMA) method in internal quality control (IQC) procedures of thyroid function tests.Methods:The serum thyroid function test results of outpatients and inpatients in the Second Hospital of Shandong University from December 1, 2022 to April 30, 2023 were collected. Based on the PBRTQC professional intelligent software system, normality correction, parameter setting, program preparation and real-time operation of test data were carried out. The results of all patients who underwent thyroid function testing between May 1, 2023 and August 31, 2023 were used as the validation dataset. The estimated EWMA value of thyroid function test results and the cumulative coefficient of variation ( CV) over 4 months were calculated. The cumulative CV was compared with the criteria of precision quality standard (1/3TEa) and the CV of IQC. Westgard 2-2s and 1-3s rules were used for alarm setting. The early warning information of the EWMA quality control program were recorded and the potential causes of performance changes were analyzed. DxLab Mind software was used to conduct normal distribution statistics for all data, and the Kolmogorov-Smirnov test was performed on the test results. Results:The items related to serum thyroid function of the patients were all positively skewed. After data correction by Box-Cox method, the PBRTQC data of free triiodothyronine (FT3) and free thyroxine (FT4) were normally distributed, and their cumulative precisions ( CV) of EWMA within 4 months were 6.26% and 2.86%, respectively, both of which were lower than the precision quality target of 8.33%. However, the data of thyroid-stimulating hormone (TSH), thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibody (TgAb) were still positive skewed after modification. The EWMA cumulative CV of TSH, TPOAb and TgAb were 13.16%, 15.31% and 16.77%, which were higher than the precision quality targets of 8.33%, 10% and 10%, respectively. The EWMA QC program can detect different out-of-control alarms, including FT4 false alarms due to sample source concentration and TSH result bias caused by changes in reagent performance. In addition, the EWMA QC program can also detect differences in FT3 results between different DXI800 fully automated chemiluminescence instrument instruments. Conclusions:The EWMA program based on PBRTQC professional intelligent software tools can monitor the patient data of the detection system in real time and continuously, dynamically identify and monitor the errors generated during the analysis process and give early warning. It can be used as a useful supplement for the daily IQC of thyroid function items, especially FT3 and FT4, and has good clinical application value.

Objective:To analyze the risk factors for postoperative pulmonary venous obstruction after correction of total anomalous pulmonary venous connection(TAPVC).Methods:We retrospectively reviewed all patients undergoing operative repair of TAPVC in our institution from December 2013 to January 2018. Patients with functionally univentricular circulations or atrial isomerism were excluded. Patients were divided into two groups according to whether there was pulmonary vein obstruction. The clinical variables of the two groups were compared. Variables for the multivariable analysis were chosen if there was statistical significance on univariable analysis.Results:145 patients were included, 91(63%) males, aged 4(2, 8)months and weight 5.5(4.5, 7.5)kg. Mean follow-up interval was(51±23) months. Postoperative obstruction developed in 27 patients(18.6%). The differences of anatomic type[supracardiac 18(67%) vs.59(50%), cardiac 4(15%) vs. 50(42%), infracardiac 3(11%) vs. 1(1%), mixed 2(7%) vs. 8(7%), P=0.003], preoperative obstruction[yes 19(70%) vs. 37(31%), no 8(30%) vs. 81(69%), P<0.001], associated cardiac lesions[yes 13(48%) vs. 27(23%), no 14(52%) vs. 91(77%), P=0.008] and bypass time[109(89, 129)min vs. 88(70, 110)min, P=0.002] between two groups were statistical significant. A multivariable model showed preoperative obstruction( P<0.001) and bypass time( P=0.009) were associated with postoperative obstruction. Conclusion:The incidence of pulmonary vein obstruction after correction of TAPVC was still high. If there was preoperative obstruction, or the bypass time was too long during operation, the surveillance of pulmonary vein obstruction should be strengthened after operation.

Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR₂) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR₂ rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR₂. All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR₂ compared with non-KIT D816 group (23.1% vs 57.1%, χ²=7.559, P=0.006), and patients with longer CR₁ duration achieved significantly higher CR₂ than those with CR₁ duration less than 12 months (74.1% vs 31.9%, χ²=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR₁ duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.

OBJECTIVE： To study the development status of TCM enterprises of Nantong city and provide suggestions， and to promote the sustainable development of TCM enterprises of Nantong city. METHODS： Taking Nantong city as an example， questionnaires were issued to 15 TCM enterprises in Nantong （including 4 TCM decoction piece enterprises， 11 TCM pharmaceutical preparation enterprises）. The statistical analysis was carried out in respects of scale structure， development （including economic development and staff） and development potential （by enterprise R&D funds and R&D personnel input intensity） of enterprises during 2013-2017. RESULTS & CONCLUSIONS： In terms of the scale and structure of the enterprise， there were no large-scale enterprises in Nantong city， only 3 medium-sized enterprises， 12 small enterprises； the overall scale of enterprises was small； the overall concentration of TCM enterprises was not high， in which the market structure of TCM decoction piece enterprises was oligopolistic， and the structure of preparation enterprises was competitive. The concentration of TCM decoction enterprises was higher than that of TCM preparation enterprises. In terms of economic development， the annual average GDP and profit growth rate are 14.98％ and 19.09％ from 2014 to 2017； the economic development situation was good， but the brand variety advantage was not developed fully. In terms of staff， employee’s education level was mainly college degree （34.01％） and the staff category was mainly salesperson （32.73％）. In terms of the company’s development potential， enterprise R&D funds and R&D personnel input intensity were in low levels （average 2.96％， 11.32％ in 5 years）， the number of patents （16 in 2013 vs. 17 in 2017） and innovative products （7 in 2013 vs. 12 in 2017） increases slowly， and only one had opened up overseas markets. In response to the issues， TCM enterprises of Nantong city or other areas should merge and reorganize appropriately to expand the scale of the industry and improve the market concentration； increase research funds and talented personnel investment， insist the protection and in novation of TCM. In addition， build a big data “healthy cloud” platform to break the traditional industrial chain； at the same time， seize the “Belt and Road” policy finance and taxation opportunities to promote overseas and develop markets to promote the sustainable development of TCM enterprise.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
