Objective:To investigate the effect of Chinese medicine He's Yangchao recipe on premature ovarian insufficiency(POI)and its relationship with mitochondrial function of ovarian granulose cells in an animal model.Methods:Thirty-six female C57BL/6J mice were randomly divided into blank control group,model group,low-,medium-and high-dose He's Yangchao recipe treatment group and coenzyme Q10(Q10)treatment group(positive control).The POI model was induced by a single intraperitoneal injection of cyclophosphamide(90 mg/kg).The animals were sacrificed after 21 days.Primary granulose cells were obtained from POI mice and treated with He's Yangchao recipe,ERβ inhibitor PHTPP,and He's Yangchao recipe+PHTPP in vitro for 24 h,respectively.Ovarian histopathological changes were observed by hematoxylin-eosin(HE)staining,ATP levels were detected by luciferase assay,mtDNA copy numbers were detected by quantitative reverse transcriptase-polymerase chain reaction(qRT-PCR),mitochondrial structure changes were observed by transmission electron microscopy,protein and mRNA expression levels of estrogen receptor β(ERβ),peroxisome proliferator-activated receptor γ coactivator 1α(PGC1α),mitochondrial transcription factor A(TFAM),and superoxide dismutase 2(SOD2)were detected by Western blotting and qRT-PCR.Results:The ovarian tissue in model group exhibited few secondary and tertiary follicles,whereas the He's Yangchao recipe groups and Q10 group had abundant secondary and tertiary follicles.Compared with the blank control group,ATP and mtDNA levels in model group decreased(P＜0.01),mitochondrial crista disappeared or abnormal vacuolated structure increased;the protein and mRNA levels of ERβ,PGC1α,TFAM,and SOD2 decreased(all P＜0.01).ATP production increased in granulose cells of high-dose He's Yangchao recipe group and Q10 group;mtDNA copy numbers increased(P＜0.05 or P＜0.01);abnormal mitochondrial structure was reduced;the protein and mRNA expressions of ERβ,PGC1α,TFAM,and SOD2 increased(P＜0.05 or P＜0.01).Compared with the PHTPP intervention group,the proportion of normal mitochondrial structure in the granulose cells of He's Yangchao recipe+PHTPP group was higher;ATP content increased(P＜0.05 or P＜0.01);mtDNA copy numbers increased(P＜0.05 or P＜0.01);the protein and mRNA expression of ERβ,PGC1α,TFAM and SOD2 increased(P＜0.05 or P＜0.01).Conclusions:He's Yangchao recipe can regulate mitochondrial biogenesis through ERβ/PGC1α/TFAM pathway to improve ovarian function in POI mice.

Objective To construct a list of quality scoring criteria for the attached sheet to the summary page of inpatient cases to achieve quantitative evaluation of the data quality.Methods It uses the Data Quality Management model of the American AHIMA as the evaluation framework to develop the list of data quality scoring criteria for the attached sheet,and score in Attached Sheet to the Summary Page of Inpatient Cases issued by the Hubei Provincial Health Commission as a demonstration.Results The average score of the 40 items in Attached Sheet to the Summary Page of Inpatient Casesis 6.725 out of 10.The main quality defects include that all items fail to clarify the person responsible for filling or the time limit for filling.In addition,some items are duplicated with the summary page(35%)or do not have a summary nature(40%).Conclusion Significant room exists for the improvement in the data quality of the attached sheet,especially in defining the person responsible and the time limit for filling in when setting up the items,making sure that the items supplement and extend the summary page,and applying effective quality control methods to the items.

Objective To observe the promoting effect of pulsed shortwave therapy on wound healing in pediatric patients with upper limb burns and explore its underlying mechanisms.Methods A total of 40 children with deep Ⅱ ° upper limb burns treated in our hospital from June 2021 to June 2023 were enrolled,and randomly divided into a control group and an observation group,with 20 cases in each group.The control group received conventional dressings,and the observation group received conventional dressings combined with pulsed shortwave therapy.The wound healing time,first appearance of skin islands on the wound,and initial number of skin islands were observed and recorded using a camera.The proportion of granulation tissue area in the wound was observed using eKare inSight 3D.The positive rate of wound bacteria was detected by collecting wound secretions for bacterial culture examination.Blood flow perfusion on the wound was measured using a blood flow meter.Results The observation group showed significantly faster wound healing and initial appearance of epithelialization(P＜0.05),and obviously higher rate of granulation tissue growth than the control group(P＜0.05).Moreover,the observation group demonstrated better control of bacterial infection in the wounds than the control group(P＜0.05).Blood flow measurement results revealed no significant increase in blood flow perfusion after pulsed shortwave therapy in the observation group(P＞0.05).However,with the elapse of time,both groups exhibited an increasing trend in blood flow perfusion(P＜0.05).Conclusion Pulsed shortwave therapy effectively promotes wound healing in pediatric patients with burns,by facilitating necrotic tissue clearance and granulation tissue regeneration,which may be associated with its non-thermal effects.

Objective:To compare the effectiveness and safety of in vitro fenestration and in situ fenestration for reconstruction of the left subclavian artery in patients with aortic arch diseases.Methods:A retrospective analysis was conducted on 80 patients with thoracic aortic dissection, aortic aneurysm, and aortic intramural hematoma involving the left subclavian artery at our center from Jan 2020 to Oct 2023.Results:Thirty-eight patients underwent in vitro fenestration to reconstruct the left subclavian artery, while 42 patients underwent in situ laser fenestration to reconstruct the left subclavian artery. The technical success rates were 97.4% and 97.6% respectively, without statistically significance ( P>0.05). Postoperative CTA examination showed that the primary rupture of the dissection was completely closed, 3 cases had type Ⅱ endoleak in vitro fenestration, and 2 cases had type Ⅱ endoleak in laser in situ fenestration. The blood flow inside the fenestration stent was fluent. During the perioperative period, one patient in the in vitro fenestration group experienced mild cerebral infarction (2.6%), one patient had mild paraplegia, and no related complications occurred in the other patients. Conclusion:For patients with aortic arch diseases, both in situ laser fenestration and in vitro fenestration are safe and effective.

Objective:To evaluate the safety and efficacy of 3D printing-assisted pre-fenestration and branch stent endovascular repair (F/b EVAR) in the treatment of thoracoabdominal aortic aneurysms.Methods:The clinical data of 26 patients treated with 3D printing-assisted F/b EVAR for complicated thoracic and abdominal aortic diseases at the Department of Vascular Surgery, the Ninth People's Hospital,Shanghai Jiaotong University School of Medicine from May 2019 to Sep 2022 were retrospectively analyzed.Results:The success rate in these 26 cases of TAAA with 3D printing combined with F/b EVAR was 97.89%, and the mean follow-up time was (8.03±4.15) months. Four cases had Ⅲc internal leakage and disappeared during the follow-up. One case of type Ⅲ leakage were narrowed during follow-up. Ic type internal leakage occurred in 1 patient and disappeared after the addition of a stent at the distal end. During the follow-up period, aortic CTA indicated that 1 patient had renal artery stent occlusion and smooth blood in other visceral branches. No complications such as organ ischemia, lower limb ischemia and all-cause death occurred during follow-up.Conclusion:3D printing-assisted F/b EVAR minimally invasive repair of TAAA is a feasible, effective and safe technique, with high success rate and low complication rate of visceral branch artery reconstruction.

Ectopic eruption of the first permanent molar is a common malocclusion in the early stage of mixed dentition. The incidence among children aged 6-10 years is 0.83%-8.7%, with an increasing trend. The main manifestation is mesial impaction of the first permanent molar during eruption, which is accompanied by the loss of root resorption and space loss of the second primary molar. Ectopic eruption of the first permanent molars can lead to underdevelopment of the dental arch and severe crowding of the posterior dentition. Prevention and early intervention are very important. The ectopic eruption of the first permanent molar is related to the disruption of the differential growth and developmental balance among the teeth, alveolar bone and jaw. In clinical practice, the diagnosis can be made according to the patient's medical history and clinical and imaging examinations, and the treatment can be performed by dividing the teeth, dividing the distal slices of the second primary molars, and distally moving the first permanent molars. This paper reviews the incidence, etiology, clinical manifestations, risks of ectopic eruption of the first permanent molar, diagnostic methods, and common treatment options to provide references for clinical treatment.

Objective:To investigate the influencing factors, periprocedural complications, and long-term outcomes of successful recanalization after endovascular treatment in patients with non-acute symptomatic internal carotid artery occlusion.Methods:Patients with non-acute internal carotid artery occlusion received endovascular treatment in the Nanjing Stroke Registration System between January 2010 and December 2021 were retrospectively enrolled. Clinical endpoint events were defined as successful vascular recanalization, periprocedural complications (symptomatic embolism and symptomatic intracranial hemorrhage), neurological function improvement, and recurrence of ipsilateral ischemic events. Multivariate logistic regression analysis was used to investigate the independent influencing factors of successful vascular recanalization. Cox proportional hazards regression analysis was used to investigate the correlation between endovascular treatment outcomes and neurological function improvement, as well as ipsilateral ischemic cerebrovascular events. Results:A total of 296 patients were included, of which 190 (64.2%) were successfully recanalized. Multivariate logistic regression analysis showed that symptoms manifest as ischemic stroke (odds ratio [ OR] 3.353, 95% confidence interval [ CI] 1.399-8.038; P=0.007), the time from the most recent symptom onset to endovascular therapy within 1 to 30 d ( OR 2.327, 95% CI 1.271-4.261; P=0.006), proximal conical residual cavity ( OR 2.853, 95% CI 1.242-6.552; P=0.013) and focal occlusion (C1-C2: OR 3.255, 95% CI 1.296-8.027, P=0.012; C6/C7: OR 5.079, 95% CI 1.334-19.334; P=0.017) were the independent influencing factors for successful vascular recanalization. Successful recanalization did not increase the risk of symptomatic intracranial hemorrhage within 7 d after procedure (3.2% vs. 0.9%; P=0.428). The median follow-up time after procedure was 38 months. Cox proportional hazards regression analysis showed that after adjusting for confounding factors, successful recanalization was significantly associated with postprocedural neurological improvement (hazard ratio 1.608, 95% CI 1.091-2.371; P=0.017), and significantly reduced the risk of recurrence of long-term ischemic events (hazard ratio 0.351, 95% CI 0.162-0.773; P=0.010). Conclusion:In patients with non-acute internal carotid artery occlusion, successful endovascular recanalization can effectively reduce the risk of long-term ischemic events without increasing the risk of symptomatic intracranial hemorrhage.

Objective:To investigate predictive factors for successful endovascular recanalization in patients with non-acute symptomatic internal carotid artery occlusion (SICAO), to develop a decision tree model using the Classification and Regression Tree (CART) algorithm, and to evaluate the predictive performance of the model.Methods:Patients with non-acute SICAO received endovascular therapy at 8 comprehensive stroke centers in China were included retrospectively. They were randomly assigned to a training set and a validation set. In the training set, the least absolute shrinkage and selection operator (LASSO) algorithm was used to screen important variables, and a decision tree prediction model was constructed based on CART algorithm. The model was evaluated using the receiver operating characteristic (ROC) curve, Hosmer-Lemeshow goodness-of-fit test and confusion matrix in the validation set.Results:A total of 511 patients with non-acute SICAO were included. They were randomly divided into a training set ( n=357) and a validation set ( n=154) in a 7:3 ratio. The successful recanalization rates after endovascular therapy were 58.8% and 58.4%, respectively. There was no statistically significant difference ( χ2=0.007, P=0.936). A CART decision tree model consisting of 5 variables, 5 layers and 9 classification rules was constructed using the six non-zero-coefficient variables selected by LASSO regression. The predictive factors for successful recanalization included fewer occluded segments, proximal tapered stump, ASITN/SIR collateral grading of 1-2, ischemic stroke, and a recent event to endovascular therapy time of 1-30 d. ROC analysis showed that the area under curve of the decision tree model in the training set was 0.810 (95% confidence interval 0.764-0.857), and the optimal cut-off value for predicting successful recanalization was 0.71. The area under curve in the validation set was 0.763 (95% confidence interval 0.687-0.839). The accuracy was 70.1%, precision was 81.4%, sensitivity was 63.3%, and specificity was 79.7%. The Hosmer-Lemeshow test in both groups showed P>0.05. Conclusion:Based on the type of ischemic event, the time from the latest event to endovascular therapy, proximal stump morphology, the number of occluded segments, and the ASITN/SIR collateral grading constructed the decision tree model can effectively predict successful recanalization after non-acute SICAO endovascular therapy.

Under the diagnosis-related groups(DRG) prospective payment system, innovative health technologies with high costs and risks may be limited to some extent. How to balance the increase of health care cost and the development of innovative health technology is a difficult problem to be solved in the current reform. By studying the relatively mature payment systems of innovative health technologies in the world, the authors found that countries generally adopted additional payment or compensation to encourage the development of new technologies. But at the same time, a relatively perfect health technology assessment and payment management mechanism had been established to ensure the standardized operation of payment plan. These international advanced experience and practice could provide references for China′s innovative health technology payment strategy under the DRG payment system. It is suggested to establish a scientific and reasonable assessment mechanism of innovative health technology, create a special access channel for innovative health technology with limited short-term evidence, and gradually form a long-term incentive mechanism of innovative health technology in DRG payment system.
