Objective To explore the correlation between serum forkhead box protein O1(FOXO1)and myeloid cell leukemia protein 1(MCL1)in patients with acute ischemic stroke(AIS)and the severity and short-term prognosis of the disease.Methods A total of 359 AIS patients admitted to the hospital from Feb-ruary 2020 to February 2023 were regarded as the study subjects.According to the National Institutes of Health Stroke Scale(NIHSS)scores at admission,359 patients were grouped into mild group(131 cases),moderate group(156 cases),and severe group(72 cases),and the patients were separated into a good progno-sis group(263 cases)and a poor prognosis group(96 cases)based on the modified Rankin Scale(mRS)score after 90 days of onset.Real-time fluorescence quantitative PCR(qPCR)was applied to detect serum FOXO1 mRNA expression level.Enzyme linked immunosorbent assay(ELISA)was applied to detect the expression level of serum MCL1.Multivariate Logistic regression analysis method was applied to analyze the factors that affected the short-term prognosis of AIS patients.Receiver operating characteristic(ROC)curve was applied to analyze the predictive value of serum FOXO1 mRNA and MCL1 expression for short-term prognosis of AIS patients.Results Compared with the mild group,the serum FOXO1 mRNA level in the moderate and severe groups was obviously reduced(P<0.05),while the MCL1 level was obviously increased(P<0.05).The FOXO1 mRNA level in the severe group was lower than that in the moderate group(P<0.05),and the MCL1 level was higher than that in the moderate group(P<0.05).Compared with the good prognosis group,the serum FOXO1 mRNA level was significantly lower in the poor prognosis group,and the level of MCL1,C-reactive protein(CRP),age,NIHSS score,and proportion of diabetes were significantly higher than those in the poor prognosis group(t/χ2=11.328,7.617,5.344,2.314,16.788,4.459,all P<0.05).The re-sults of multivariate Logistic analysis showed that FOXO1 mRNA was a protective factor for the short-term prognosis of AIS patients(OR=0.726,P<0.05),while MCL1,CRP,and NIHSS score were independent risk factors affecting the short-term prognosis of AIS patients(OR=1.334,1.319,1.442,P<0.05).The results of ROC curve showed that the area under the curve(AUC)of serum FOXO1 mRNA level for predicting poor short-term prognosis of AIS patients was 0.807,with sensitivity and specificity of 69.79%and 85.93%re-spectively.The AUC of serum MCL1 level for predicting poor short-term prognosis of AIS patients was 0.824,with sensitivity and specificity of 71.87%and 84.79%,respectively.The AUC of the combination of serum FOXO1 mRNA and MCL1 for predicting poor short-term prognosis of AIS patients was 0.886,with sensitivity and specificity of 85.42%and 81.37%,respectively.Conclusion The expression of FOXO1 mRNA and MCL1 is abnormal in AIS patients,they are related to the severity of AIS and have high predictive value for the short-term prognosis of AIS.

OBJECTIVE: To investigate the effectiveness of single Taylor external fixator combined with biplanar osteotomy on correction of tibial multiplanar deformities. METHODS: Between October 2016 and December 2021, 11 patients with tibial multiplanar deformities (20 sides) were treated with single Taylor external fixator and biplanar osteotomy. Of them, 4 were male and 7 were female; the average age ranged from 13 to 33 years (mean, 21.9 years). Diagnosis included rickets severe genu varum deformity (7 cases, 14 sides), rickets severe genu valgum deformity (2 cases, 4 sides), multiple osteochondromatosis calf deformity (1 case, 1 side), neurofibromatosis medial lower leg anterior arch deformity with short of leg (1 case, 1 side). After fibular osteotomy and tibial multiplanar osteotomy, a Taylor external fixator was installed. After operation, the deformities were corrected successively and fixed completely. The osteotomy healed, then the external fixator was removed. Before operation and at 12 months after operation, the full-length X-ray films were taken. The leg-length discrepancy, medial proximal tibial angle (MPTA), lateral distal tibial angle (LDTA), posterior proximal tibial angle (PPTA), anterior distal tibial angle (ADTA), and tibial rotation angle were measured. The degree of lower limb deformity was scored with reference to a customized tibial mechanical axis scoring table. RESULTS: Osteotomy was successfully completed without neurovascular injury and other complications. The external fixator was adjusted for 28-46 days, with an average of 37 days, and the external fixator was worn for 136-292 days, with an average of 169 days. Mild needle infection during the fixation period occurred in 3 sides, refracture at the distal tibial osteotomy in 1 side after removing the external fixator, and nonunion of the distal fibular osteotomy in 1 side. All patients were followed up 369-397 days (mean, 375 days). At 12 months after operation, the lower limb discrepancy decreased, but there was no significant difference ( P>0.05). MPTA, LDTA, PPTA, ADTA, and tibial rotation angle improved, and the differences in LDTA, ADTA, and tibial rotation angle were significant ( P<0.05). The score of lower limb deformity was significantly higher than that before operation ( P<0.05), and the results were excellent in 9 sides, good in 8 sides, fair in 3 sides, with the excellent and good rate of 85%. CONCLUSION Single Taylor external fixator combined with biplanar osteotomy is effective in the correction of tibial multiplanar deformities.

Objective:To investigate the clinical effect of free anterolateral thigh perforator flap(ALTPF) in reconstruction of temporal scalp defect after blood circulation reconstruction surgery for moyamoya disease.Methods:From May 2020 to July 2022, 7 patients with scalp defect after revascularisation of moyamoya disease were treated in Department of Hand and Foot Microsurgery, Henan Provincial People’s Hospital (People’s Hospital of Zhengzhou University). The patients were 4 males and 3 females, aged 33-59 years old, at 43 years old in average. There were 5 defects in left tempus and 2 in right tempus. The sizes of scalp defect were 4.5 cm × 5.5 cm-7.5 cm × 9.5 cm. Debridement and VSD management were primarily performed. After wounds were stabilised, ultrasound location of perforator vessels of ALTPFs was performed. Having confirmed that the perforator vessels were suitable for the surgical requirements, flap transfers were then performed. The descending branch of the lateral femoral circumflex artery was end-to-side anastomosed with the superficial temporal artery, and the descending branch of the lateral femoral circumflex vein was end-to-end anastomosed with the superficial temporal vein. Postoperative follow-up was conducted through outpatient clinic visits, telephone and WeChat reviews. Appearance, texture of ALTPFs and the flap donor sites were observed in follow-ups. Comparisons of the changes of nervous system before and after surgery were made. Cognitive function of the patients was assessed with the Mini Mental State Examination (MMSE), together with the Activities of Daily Living (ADL) .Results:All 7 flaps survived. One flap had vascular compromise 6 hours after surgery, and was rectified after surgical intervention. All the patients were included in the postoperative follow-up for 7-33 (average 19) months. All flaps had good appearance with soft texture. There was no obvious difference in colour comparing with the skin around the recipient region. The donor sites healed well without hypertrophic scar. Examinations of nervous system of the patients were found the same as that before surgery. Using Manual Muscle Testing (MMT), the average limb muscle strength of the patients was 4 before surgery and 4 after surgery, without change; Using the Ashworth assessment scale, the average preoperative and postoperative limb muscle tension in this group of patients was 1, without change; The Berg balance scale was used to evaluate the patient's balance function, with an average score of 42 before surgery and 42 after surgery, without any changes; There was no change in limb sensation before and after surgery; Using the MMSE, the average preoperative score and postoperative score of this group of patients were 25 points, without any change. Using the modified Barthel index scoring standard, the average preoperative score for this group of patients was 75 points, and the average postoperative score was 79 points, and the ADL of the patient had improved to various levels.Conclusion:Reconstruction of scalp defect with free ALTPF after revascularisation of moyamoya disease has obvious advantages, such as it closes the wound quickly, prevents infection and achieves a good appearance. This surgical procedure can produce a good clinical effect.

Objective:To understand the identification and medical observation of close contacts of COVID-19 cases in a city and provide scientific basis for the adjustment of the epidemic prevention and control strategies.Methods:Descriptive epidemiological methods were used to analyze the general characteristics of all the close contacts of COVID-19 cases in a city. Throat swabs were collected from the close contacts for real-time fluorescent RT-PCR. The confirmed cases were diagnosed according to diagnosis and treatment of COVID-19 (trial version 5).Results:Among the 1 665 close contacts of COVID-19 cases in a city, 10 were diagnosed as COVID-19 cases during the medical observation period, accounting for 30.30% of all the confirmed cases in a city, most of them were close relatives of the confirmed cases. The longest contact time with the confirmed cases was 8 days and the shortest was 0 days. Ten COVID-19 cases in close contacts constituted to six family clusters.Conclusions:In COVID-19 prevention and control in a city, the active tracking of the transmission chains of the confirmed cases and timely identification of the close contacts were conducted. The people who had close contacts with the confirmed COVID-19 cases within 14 days before onset were all placed under medical observation, which played a key role in the effective prevention and control of COVID-19 epidemic in a city. Nearly one third of COVID-19 cases occurred during the medical observation period, so the infection sources were effectively controlled and transmission routes were effectively blocked, which greatly facilitated the prevention of the clusters of COVID-19 cases.

Objective:To compare the short-term efficacy and perioperative safety of neoadjuvant chemoradiotherapy (nCRT) with total neoadjuvant treatment (TNT) in patients with locally advanced rectal cancer (LARC).Methods:A retrospective cohort analysis was carried out. Inclusion criteria: (1) rectal adenocarcinoma confirmed by pathology with a distance from tumor inferior border to anal verge within 12 cm; (2) clinical stage cT3-4N0 or cT1-4N1-2 diagnosed by magnetic resonance imaging (MRI) or endorectal ultrasonography; (3) a single rectal tumor confirmed by colonoscopy; (4) patients suitable for chemoradiotherapy; (5) no previous history of other tumors. Exclusion criteria: (1)patients with previous rectal cancer surgery and local recurrence; (2) those who did not complete nCRT course; (3) those with distant metastases; (4) those with defective clinicopathological data. According to the above criteria, a total of 134 LARC patients at the Department of General Surgery of Beijing Chaoyang Hospital from January 2016 to January 2019 were enrolled, including 82 males and 52 females, with a male-female ratio of 1.58∶1.00 and mean age of (59.6±11.2) (26-81) years. Based on neoadjuvant regimen, patients were divided into nCRT group ( n=55) and TNT group ( n=79). There were no statistically significant differences in baseline data, such as age, sex, distance from tumor to anal verge, Eastern Cooperative Oncology Group (ECOG) performance status and clinical TNM stage, between the two groups (all P>0.05). All the patients received pelvic intensity-modulated radiotherapy (IMRT) with a total dose of 50.4 Gy in 28 fractions. Patients in nCRT group received oral capecitabine chemotherapy during radiotherapy and underwent surgery 6-8 weeks after chemoradiation. Patients in TNT group received one cycle of induction CapeOX (oxaliplatin and capecitabine) and concurrent chemoradiotherapy, then underwent a radical surgery two weeks after completion of consolidation chemotherapy. The efficacy of neoadjuvant therapy, adverse events of chemoradiotherapy and perioperative safety were compared between the two groups. Results:Patients of two groups completed the course of neoadjuvant therapy. There were no statistically significant differences between nCRT group and TNT group in the incidence of adverse events in neutropenia [7.3% (4/55) vs. 10.1% (8/79)], anemia [3.6% (2/55) vs. 3.8% (3/79)], thrombocytopenia [5.5% (3/55) vs. 7.6% (6/79)], gastrointestinal dysfunction [3.6% (2/55) vs. 6.3% (5/79)] and radiation enteritis [9.1% (5/55) vs. 8.9% (7/79)] (all P>0.05). One hundred and thirty patients completed TME surgery, including 54 patients in nCRT group and 76 patients in the TNT group. Compared with the nCRT group, the proportion of abdominoperineal resection (APR) was higher in the TNT group [31.6% (25/76) vs. 13.0% (7/54), χ 2=9.382, P=0.009]. No statistically significant differences in morbidity of postoperative complication, operation time, intraoperative blood loss and postoperative hospital stay between the two groups were found (all P>0.05). The distal and circumferential margins were negative in all the patients. Seventeen patients in the TNT group 22.4% (17/76) got pathologic complete response (pCR), which was significantly higher than 7.4% (4/54) in nCRT group (χ 2=5.217, P=0.022). There were no statistically significant differences in ypTNM classification, perineural invasion and venous invasion between the two groups (all P>0.05). Conclusion:The pCR of TNT is higher than that of nCRT without increasing the incidence of toxicity and complications of radiotherapy and chemotherapy for patients with locally advanced rectal cancer.

Objective: To describe the general and histological features of the full-length superficial fascia of the circumferential upper limb. Methods: Fresh frozen arm specimens were dissected, and then MRI imaging in vivo, enhanced CT angiography and HE histological staining were used to describe the characteristics of the full-length superficial fascia of the circumferential arm and its relationship with important blood vessels. Results: The four typical structures of the superficial fascia of the arm were divided into subcutaneous superficial fat, membrane-like substance, deep fat and deep fascia from superficial to deep. The thickness and stratification, fusion degree and histological characteristics of the superficial fascia of these four layers were obviously different in different levels and regions of the arm. MRI confirmed that the total thickness of superficial fascia gradually decreased from shoulder to wrist. Venography showed that the cephalic vein ran below the second layer of superficial fascia and above the deep fascia. The basilic vein originated from the dorsal vein network of the hand and always lied below the second layer of membranous material until the basilic vein penetrates below the deep fascia of the upper arm. Conclusions The deep understanding of the circumferential full-length of superficial fascia structure of the upper limb provides an important theoretical basis for improving the surgical safety and fine operation for the Dynamic Arm Circumferential Liposuction.
