BACKGROUND: The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results. OBJECTIVE: To identify factors and their impact on the treatment effect of acupuncture in different outcomes. METHODS: Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects. RESULTS: The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01). CONCLUSIONS High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

Objective To conduct an epidemiological survey of common congenital heart disease(CHD)among children in ethnic minority areas in southeastern Guizhou and to explore the influencing factors of delayed medical treatment.Methods From January 2019 to July 2022,18 850 children aged 3 months to 14 years in Qiandongnan Miao and Dong Autonomous Prefecture were selected;105 children with CHD were included in the training set,and they were divided into delayed group(80 cases)and non-delayed group(25 cases)according to whether or not to delay medical treatment.In addition,children with CHD(35 cases)from July 2022 to December 2022 were included in the validation set.The general data of the subjects in the two groups were compared and ana-lyzed.Multivariate logistic regression was performed and risk scoring model was constructed.Results The preva-lence of CHD in 18 850 children was 5.57‰(105/18 850),with the highest prevalence in Liping County,and the lowest in Huangping County.The proportion of children with secondary atrial septal defect was the highest,and that of the aortic valve malformation was the lowest.Among the complex cases of CHD,the proportion of children with single type was the highest,and that of children with three or more types were the lowest.Among children with CHD,the rate of delayed medical treatment was 76.19% (80/105).The median delay in medical treatment was 12 months,with an average of(18.78±4.77)months.Multifactor logistic regression analysis showed that heart murmur(level 2～3),less-educated(primary and secondary school)guardian,family per capita income<2 000 yuan,and frequent drinking of the guardian were independent risk factors for delayed medical treatment(P<0.05),and commercial settlement of medical expenses was independent protective factor(P<0.05).Risk scoring model divided the children into three groups:low risk(≤80 points),medium risk(>80 points and≤134 points)and high(>134 points)risk group.The evaluation of the model show that it was accurate,effective,safe,and reliable.Conclusion The highest prevalence is observed in Liping County.The proportion of children with secondary atrial septal defect and the proportion of children with single type are the highest.Delayed medical treat-ment is found in most of the children with CHD.Cardiac murmur,education background of the guardian,per capita family income,guardian alcohol consumption,and medical expense settlement method are all independent influencing factors for delayed medical treatment.

Objective To compare the clinical effects between sutureless bridge intrascleral fixation and ciliary sul-cus suture suspension of intraocular lens(IOL)1 year postoperatively.Methods In this retrospective study,14 patients(14 eyes)who underwent sutureless bridge intrascleral IOL fixation in the No.988 Hospital of Joint Logistic Support Force of PLA from March 2019 to January 2022 were taken as the intrascleral fixation group and 15 patients(15 eyes)who under-went IOL ciliary sulcus suture suspension in the same period were taken as the suture suspension group.During the 1-year follow-up,the preoperative and postoperative uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA)(logMAR),spherical equivalent(SE),endothelial cell count(ECC),intraocular pressure(IOP)and IOL position were compared between the two groups.Results At 1,6 and 12 months postoperatively,the UCVA in both groups significant-ly increased compared with those before surgery(all P＜0.05),and UCVA in the intrascleral fixation group were better than those in the suture suspension group at all postoperative time points(F=4.560,6.411 and5.373;all P＜0.05).At 1,6 and 12 months postoperatively,there was no significant difference in BCVA in both groups compared with those before surgery(all P＞0.05),but BCVA in the intrascleral fixation group were better than those in the suture suspension group at all postoperative time points(F=6.170,6.957 and 10.624;all P＜0.05).After surgery,eyes in the intrascleral fixation group showed hyperopia drift,while eyes in the suture suspension group showed myopia drift.At 1,6 and 12 months post-operatively,the SE of the intrascleral fixation group were(0.59±0.30)D,(0.57±0.27)D and(0.64±0.29)D,respec-tively,and those of the suture suspension group were(-0.75±0.44)D,(-0.72±0.42)D and(-1.12±0.64)D,re-spectively.At 6 months postoperatively,the ECC of both groups were significantly lower than those before surgery(t=8.579 and 21.929;both P＜0.001).The IOP in both groups were within the normal range preoperatively and stable during the follow-up.The IOL were centrally located without obvious decentration or tilt during the follow-up.In addition,there were no vitreous and retinal complications.Conclusion Both sutureless bridge intrascleral IOL fixation and IOL ciliary sulcus suture suspension can obtain a favorable prognosis of visual acuity with refractive shift,while sutureless bridge in-trascleral fixation shows better clinical outcomes.

The COVID-19 epidemic has spread to the whole world for three years and has had a serious impact on human life, health and economic activities. China's epidemic prevention and control has gone through the following stages: emergency unconventional stage, emergency normalization stage, and the transitional stage from the emergency normalization to the "Category B infectious disease treated as Category B" normalization, and achieved a major and decisive victory. The designated hospitals for prevention and control of COVID-19 epidemic in Tianjin has successfully completed its tasks in all stages of epidemic prevention and control, and has accumulated valuable experience. This article summarizes the experience of constructing a hospital infection prevention and control system during the "Category B infectious disease treated as Category A" period in designated hospital. The experience is summarized as the "Cluster" hospital infection prevention and control system, namely "three rings" outside, middle and inside, "three districts" of green, orange and red, "three things" before, during and after the event, "two-day pre-purification" and "two-director system", and "one zone" management. In emergency situations, we adopt a simplified version of the cluster hospital infection prevention and control system. In emergency situations, a simplified version of the "Cluster" hospital infection prevention and control system can be adopted. This system has the following characteristics: firstly, the system emphasizes the characteristics of "cluster" and the overall management of key measures to avoid any shortcomings. The second, it emphasizes the transformation of infection control concepts to maximize the safety of medical services through infection control. The third, it emphasizes the optimization of the process. The prevention and control measures should be comprehensive and focused, while also preventing excessive use. The measures emphasize the use of the least resources to achieve the best infection control effect. The fourth, it emphasizes the quality control work of infection control, pays attention to the importance of the process, and advocates the concept of "system slimming, process fattening". Fifthly, it emphasizes that the future development depends on artificial intelligence, in order to improve the quality and efficiency of prevention and control to the greatest extent. Sixth, hospitals need to strengthen continuous training and retraining. We utilize diverse training methods, including artificial intelligence, to ensure that infection control policies and procedures are simple. We have established an evaluation and feedback mechanism to ensure that medical personnel are in an emergency state at all times.

Objective:To investigate the prognostic factors for the risk of prolonged postoperative ileus (PPOI) after colorectal cancer resection.Methods:The clinical data of 896 patients undergoing radical colorectal cancer resection at Affiliated Hospital of Qingdao University between Jan 2016 and Dec 2022 were retrospectively analyzed. Patients were divided into PPOI group (59 cases) and non-PPOI group (837 cases) according to whether PPOI happened after surgery. Potential prognostic factors for the risk of developing PPOI were analyzed by univariate and multivariate Logistic regression. The receiver operating characteristic curve analysis was performed to assess the predictive power of potential prognosis factors.Results:Fifty-nine patients (6.5%) developed PPOI after radical colorectal cancer resection. Univariate and multifactorial logistic regression analyses showed that diabetes mellitus ( OR=2.360, P=0.018), preoperative albumin level <35 g/L ( OR=2.196, P=0.036), postoperative epidural analgesia ( OR=2.399, P=0.007), open surgery ( OR=3.413, P=0.001), and ICU hospitalization ≥ 48 h ( OR=6.134, P<0.001) were independent prognostic factors for PPOI. Combining the above prognostic factors to construct the receiver operating characteristic curve yielded an area under the curve of 0.806 (95% CI: 0.698-0.838), with an accuracy, sensitivity and specificity of 73.9%, 74.0%, 72.9%, respectively. Conclusion:Diabetes mellitus, preoperative albumin level, postoperative epidural analgesia, open surgery, and ICU hospitalization ≥ 48 h were risk factors for PPOI after radical colorectal cancer resection.

Age-related macular degeneration(ARMD)is a neurodegenerative disease associated with oxidative stress. It is characterized by progressive death of photoreceptors and retinal pigment epithelium(RPE), and is one of the leading causes of irreversible loss of central vision in patients over the age of 65 years old. MicroRNA(miRNA)is a class of regulatory short-chain non-coding RNA that can bind and inhibit multiple gene targets in the same biological pathway. This unique property makes microRNA an ideal target for exploring the pathogenesis, diagnosis and treatment of non-exudative ARMD. Previous studies have found that the pathogenesis of non-exudative ARMD involves age, genetics, environment, oxidative stress, lipid metabolism, autophagy and immunity. However, the exact mechanisms have not been fully clarified. As biomarkers of non-exudative ARMD, miRNA play a role in oxidative stress and lipid metabolism. This article summarizes the role of various miRNA in targeting Nrf2 and HIF-1α to inhibit hypoxia-related angiogenesis signaling, thereby affecting oxidative stress. Additionally, miRNA regulate lipid uptake and the expression of ABCA1 in RPE and macrophages, thereby influencing lipid metabolism. This deepens the understanding of the role of miRNA in oxidative stress and lipid metabolism in non-exudative ARMD, and provides directions for further improving the understanding of the pathogenesis and prevention of non-exudative ARMD.

Objective:To investigate the clinicopathological, immunohistochemical, and molecular genetic characteristics of microsecretory adenocarcinoma (MSA) of the salivary gland, and to improve the understanding of this rare tumor.Methods:Cases originally diagnosed as MSA at the Department of Oral Pathology, the Ninth People′s Hospital of Shanghai Jiao Tong University School of Medicine were retrospectively collected. The cases of polymorphous adenocarcinoma and adenocarcinoma, not otherwise specified from January 2000 to January 2020 were reviewed to identify potential misdiagnosed MSA cases. Clinicopathological analysis and follow-up of all confirmed MSA cases were performed, and relevant literature was reviewed.Results:A total of 4 MSA cases were identified, including 2 screened from the polymorphous adenocarcinoma cohort. Of the 4 MSA patients, 3 were male and 1 was female, with an average age of 53 years (range, 37-67 years). Three cases occurred in the palate, and one in the buccal region. The clinical manifestation was usually a slow-growing painless mass. Tumors were generally small, with a maximum diameter ranging from 0.7 to 1.8 cm (average, 1.2 cm). Microscopically, the tumor was unencapsulated and showed an infiltrative growth pattern. The tumor cells appeared small in size and showed bland, cubic and flattened cytological features, forming microcystic lumens and glandular tubes. Significant basophilic secretions were seen in the lumens. Between the tumor nests there was fibro-myxoid stroma. Immunohistochemistry showed diffusely or partially positive staining for cytokeratin 7, S-100, SOX-10, p63 and vimentin and negative staining for p40, mammaglobin, and calponin. The proliferation index of Ki-67 was relatively low (1%-3%). Four MSA cases all harbored SS18 gene rearrangement as shown by fluorescence in situ hybridization (FISH), including 2 cases with MEF2C::SS18 fusion gene through RNA-targeted next generation sequencing. All 4 patients underwent surgical resection without any adjuvant treatments. Three patients were followed up for a period of 2 to 203 months. No tumor recurrence, metastasis, or disease-related death was found.Conclusions:Salivary gland MSA is a novel and rare low-grade carcinoma with unique and consistent histological morphology, immunophenotype, and molecular changes. Immunohistochemical staining and SS18 break apart FISH are useful for the diagnosis of the tumor with atypical morphology and high-grade transformation.
