Objective@#To assess the effectiveness of online and offline myopia prevention and control health education interventions using wearable behavior monitoring tools for non myopic elementary school students,so as to provide evidence based medical support for public health practices.@*Methods@#From May to June in 2021, two schools were selected within the same county in Jiangsu Province. School 1 conducted online and offline parental health education ( n =111), while school 2 exclusively conducted offline health education activities, representing the traditional intervention group ( n =122). Students from both schools underwent monitoring through wearable behavior tracking tools, with feedback reports provided (eye distance, eye duration, ambient light, and outdoor exposure time). Both schools relied on activities to carry out health education interventions, and organized the distribution of promotional materials and display boards. The intervention group also established WeChat groups to conduct online "Healthy Parents Action" (answering and providing feedback on health knowledge related to myopia prevention and control, myopia prevention and control, science popularization, etc. raised by parents). Evaluation criteria included myopia rates, post dilation refractive error, and axial length, with a tracking period of two years (from 2021 to 2023). Additionally, the study collected refractive parameters from non myopic students who did not participate in wearable tool monitoring in the 12 classes across the two schools.@*Results@#The baseline results indicated that there were no significant differences between the two groups in terms of refractive parameters and wearable tool monitoring results (including screen time, viewing distance, outdoor exposure time, and homework light exposure)( t/Z/χ 2=1.94,1.17,0.58,0.40,0.80,0.69,0.32, P >0.05). After a two-year follow up, in the first and second year, the myopia rate of the online Healthy Parents Action group (11.4%, 29.7%) were lower than that of the traditional group (26.2%, 50.9%), and the degree of refractive change in the intervention group [0.63(0.38,1.19)D] was lower than that of the traditional group [0.91(0.40,1.50)D], and all the differences were statistically significant( χ 2/ Z =4.93，10.37，2.29， P <0.05). However, there were no significant differences ( P >0.05) in axial length changes between the two groups over the twoyear intervention period. Nevertheless, in the second year, the axial length change in the traditional group [0.35(0.20,0.65)mm] was lower than that in the natural observation group [0.55(0.30,0.75)mm], and this difference was statistically significant ( Z =1.92, P <0.05).@*Conclusions@#Online and offline myopia prevention and control health education can effectively reduce myopia rates. The intervention mode combining wearable behavior monitoring tools with online health education may have better effects, but further large sample and multi center studies are needed to provide additional evidence and confirmation.

Purpose@#Reports showed that some of intrahepatic cholangiocarcinoma (ICC) patients with lymph node metastasis (LNM) may also gain survival benefit undergone resection. However, the effect of the extent of LNM on prognosis and surgical indication is barely discussed. @*Methods@#From September 1994 to November 2018, primary ICC patients undergone initial curable surgery were enrolled. Based on the extent of LNM, we divided these patients into 4 groups, including patients with no LNM (group N0), LNM to hepatoduodenal ligament or common hepatic artery (region A, group A), LNM to gastrohepatic lymph nodes for left liver ICC and periduodenal and peripancreatic lymph node for right liver ICC (region B, group B), or LNM beyond these regions (region C, group C). Multivariable Cox regression analysis was performed to identify the prognostic factors for recurrencefree survival (RFS) and overall survival (OS) in all groups. @*Results@#A total of 133 patients were enrolled. There were 56, 21, 17, and 39 patients in groups N0, A, B, and C, respectively. There was significant difference between groups N0 and C in RFS (P < 0.001) and OS (P = 0.002). When we compared group N0 + A + B with group C, we also found that RFS (P < 0.001) and OS (P = 0.007) were significantly different. In multivariable analysis, the extent of LNM was an independent risk factor for RFS (P < 0.050). @*Conclusion@#ICC patients with the LNM to regions A and B could still achieve good prognosis with resection. Surgery should be carefully considered when LNM to region C.

Objective:Based on network pharmacology and molecular docking to explore the targets and mechanism of Xiaoyong Sanjie Formula treating Non-Puerperal Mastitis (NPM).Methods:By retrieving the active components and the corresponding target information of each component in Xiaoyong Sanjie Formula with Pharmacology Database and Analysis Platform of Chinese Medicine System (TCMSP), and NPM-related genes in database like GeneCard, OMIM, PharmGkb, TTD, and DrugBank, the data of the core targets of Xiaoyong Sanjie Formula and disease-related genes was compared to obtain intersecting genes, and the STRING database was used to analyze the protein interaction network and find the core genes. With the help of Cytoscape 3.8.0, the active ingredient-target-pathway regulation network diagram of Xiaoyong Sanjie Formula for the treatment of NPM was established. The R language pack was used to enrich the targets with GO function and KEGG pathway enrichment, and the potential targets and mechanism of Xiaoyong Sanjie Formula in the treatment of NPM were explored. Finally, molecular docking verification was carried out to analyze the effecacy of key components and potential core targets of Xiaoyong Sanjie Formula.Results:Network pharmacological analysis showed that there were 47 active component and 1 692 NPM-related potential targets in Xiaoyong Sanjie Formula, and 235 core targets of NPM in the treatment of Xiaoyong Sanjie Formula. The key components of Xiaoyong Sanjie Formula in the treatment of NPM include Quercetin, Naringenin, Kaempferol, Diosgenin, Luteolin, etc., with the core targets of intercellular adhesion molecule-1 (ICAM-1), vascular endothelial growth factor (VEGFA), tumor necrosis factor (TNF), interleukin-6 (IL-6), Epidermal growth factor receptor (EGFR), interleukin-1β (IL-1B), chemokine-8 (CXCL8), chemokine-2 (CCL2), etc. GO enrichment obtained 1 492 biological process entries. The KEGG pathway is enriched to obtain 105 pathways, including the TNF signaling pathway, the PI3K-Akt signaling pathway, the NF-kappa B signaling pathway, and the JAK-STAT signaling pathway, IL-17 signaling pathway, C-type lectin receptor signaling pathway, etc. The final molecular docking verified that the key active ingredients of Xiaoyong Sanjie Formula could bind with the potential core targets closely.Conclusion:Xiaoyong Sanjie Formula can treat NPM with multi-component, multi-target characteristics,which plays a role of treating NPM through signaling pathways such as immuno-inflammatory response, the metabolism of the medicine, cellular adaptive stress response, and vascular function regulation.

Objective:To correlate neoadjuvant radiotherapy and chemotherapy efficacy with changes in peripheral blood T lymphocytes in patients with advanced mid-to-low rectal cancer.Methods:A total of 106 patients with rectal cancer who received treatment in Jinhua Municipal Central Hospital from January 2019 to December 2020 were included in this study. Fasting venous blood was taken before neoadjuvant radiotherapy and chemotherapy and 7 days before surgery to measure the numbers of CD3 +, CD4 +, CD8 +, CD45RA + and CD45RO + cells using flow cytometry. The optimal cut-off point was determined using the receiver operating curve. The influential factors of tumor regression grade were analyzed using logistic regression analysis. Results:After neoadjuvant radiotherapy and chemotherapy, the numbers of CD3 +, CD4 +, CD8 + cells were (401.86 ± 138.65), (225.83 ± 87.17), and (155.84 ± 71.19) respectively, which were significantly decreased compared with before neoadjuvant radiotherapy and chemotherapy [(477.33 ± 141.74), (647.38 ± 203.19), (348.22 ± 113.75), t = 10.78, 11.17, 9.49, all P < 0.05]. There were no significant differences in the percentages of CD3 +, CD4 +, CD8 +, CD45RA + and CD45RO + cells between before and after treatment (all P > 0.05). The percentage of CD45RO + cells was significantly increased after neoadjuvant radiotherapy and chemotherapy. A higher percentage of CD45RO + cells led to a lower tumor regression grade ( P < 0.05). The receiver operating characteristic curve showed that the optimal cut-off point of the percentage of CD45RO + cells was 1.08. The area under the receiver operating characteristic curve was 0.774 ( P = 0.029), with a sensitivity of 82.5% and specificity of 69.6%. The logistic regression analysis revealed that the percentage of CD45RO + cells was significantly correlated with tumor regression grade ( P < 0.05). Conclusion:The percentage of CD45RO + cells in T lymphocyte subsets before and after neoadjuvant radiotherapy and chemotherapy is closely related to tumor regression grade. It can be used as an indicator to predict the sensitivity of neoadjuvant radiotherapy and chemotherapy. This study is of great innovation and science and provides a new idea for clinical practice.

@#Abstract To describe the clinical features of myelin oligodendrocyte glycoprotein antibody-related diseases associated with seizures. MethodsPatients with positive blood or cerebrospinal fluid MOG antibody test who were admitted to the Fifth Affiliated Hospital of Zhengzhou University and the First Affiliated Hospital of Zhengzhou University from April 2016 to April 2021 were retrospectively analyzed to understand the general data，clinical features，laboratory examination，imaging examination，EEG results，treatment and prognosis of patients with seizures in the course of the disease. ResultsFifteen patients（21.4%，15/70）with positive MOG antibody had seizures at the first onset，including 11 children and 4 adults，with an average onset age of 17.4 years（3-53 years）. The clinical manifestations were ADEM-like in 6 cases，unilateral cortical encephalitis in 5 cases，isolated seizures in 3 cases and anti-NMDAR encephalitis in 1 case. The types of epileptic seizures are generalized tonic-clonic seizures in 10 cases，focal motor seizures in 3 cases and status epilepticus in 2 cases. In addition to headache，fever and corresponding cortical related symptoms，it can also involve the brain stem，optic nerve and spinal cord. In the acute phase，EEG is often abnormal，and slow-wave changes appear in the cortex area corresponding to the involved side.Head MRI often shows cortical involvement，showing local cortical swelling，shallow sulcus，the high signal in FLAIR，and enhanced meningeal linear enhancement. Glucocorticoid or combined with human immunoglobulin is effective in the acute phase. After 2-31 months follow up，6 patients relapsed，5 patients were treated with immunosuppressant，and 10 patients were prolonged with antiepileptic drugs. ConclusionsSeizures is common in MOG antibody related diseases，mostly in the clinical phenotype of ADEM and unilateral cortical encephalitis. The most common seizure type is a generalized tonic-clonic seizure，and the cortex on the affected side of EEG shows slow wave changes. Head MRI usually involves cerebral cortex and subcortical white matter，and some patients with isolated epilepsy may have typical demyelinating changes afterwards. Immunotherapy is effective in the acute stage，and some patients need to be treated with immunosuppressants and extended antiepileptic drugs.

Objective:To analyze the effects of proton pump inhibitors(PPIs)on the prevention of stress ulcers(SU)in elderly patients with acute respiratory distress syndrome(ARDS), and to analyze related factors for the risk of short-term death.Methods:This study was a multicenter retrospective cohort study.Two hundred elderly ARDS patients diagnosed and treated at Peking University International Hospital, Anzhen Hospital and Ezhou Central Hospital from November 2017 to December 2019 were continuously included.These patients were treated with PPIs(omeprazole, pantoprazole, rabeprazole, lansoprazole and esomeprazole)within 48 hours after ICU admission to prevent SU and were considered as the PPI group.According to the propensity score matching method, 200 elderly ARDS patients admitted to the hospitals with similar ages, medical history and sequential organ failure assessment(SOFA)scores who did not use PPIs were selected as the control group.All patients were followed up for 30 days.Kaplan-Meier survival analysis and the log-rank test were used to compare the 30-day mortality risk between the two groups.Cox regression analysis was used to analyze the relevant factors affecting the 30-day mortality.The 30-day mortality risk and the incidence of clinically significant gastrointestinal bleeding were evaluated among patients using different PPIs.Results:The average time of PPI use was 8.4±4.4 d in the PPI group.In the control group, 38.0% of patients were treated with H 2 receptor antagonists, and the average time of use was 8.1±5.2 days.There was no significant difference in the 30-day all-cause mortality risk between the two groups(20.5% or 41 cases vs.23.5% or 47 cases, P>0.05). The incidences of clinically significant upper gastrointestinal tract bleeding(2.5% or 5 cases vs.7.0% or 14, P<0.05), gastrointestinal bleeding(5.5% or 11 cases vs.12.5% or 25 cases, P<0.05)and hospital-acquired pneumonia(9.0% or 18 vs.4.0% or 8 cases, P<0.05)had significant differences between the PPI group and the control group.Multivariate Cox regression analysis showed that age>70 years( HR=1.845, 95% CI: 1.131-3.010, P<0.05), arterial oxygen partial pressure <78.0 mmHg(1 mmHg=0.133 kPa, HR=2.143, 95% CI: 1.317-3.487, P<0.01), SOFA score>14( HR=3.603, 95% CI: 1.741-7.456, P<0.01)and blood lactic acid>3.8 mmol/L( HR=2.725, 95% CI: 1.437-5.167, P<0.01)were related factors for the 30-day mortality.Compared with the control group, there was no significant difference in 30-day mortality between the five subgroups taking different PPIs including omeprazole, pantoprazole, rabeprazole, lansoprazole and esomeprazole( P>0.05), and the incidence of clinically significant gastrointestinal bleeding was significantly reduced( P<0.05), but there was no significant difference between the five PPIs subgroups( P>0.05). Conclusions:Although PPIs have no effect on short-term death in elderly ARDS patients, it can increase the risk of hospital acquired pneumonia while reducing the occurrence of gastrointestinal bleeding.With PPI use, advanced age, low arterial oxygen partial pressure, high SOFA score and high blood lactate are risk factors for the 30-day mortality.

Objective:To investigate the transcript factor Foxp1 mRNA expression in peripheral blood CD4 +T cells of patients with myasthenia gravis (MG), and the changes of Foxp1 mRNA expression before and after tacrolimus immunotherapy. Methods:A prospective study was performed. Twenty-six MG patients admitted to our hospital from January 2018 to January 2020 and 18 healthy controls accepted physical examination in our hospital from January 2018 to July 2019 were recruited. Quantitative myasthenia gravis score (QMGs) was used to assess MG severity. Peripheral blood mononuclear cells (PBMCs) were isolated from the peripheral venous blood of MG patients before treatment and 6 months after treatment, and healthy controls right after enrollment by density gradient centrifugation; CD4 +T cells were isolated from PBMCs by magnetic cell separation. The Foxp1 mRNA expression was detected by real-time fluorescent quantification PCR (RT-qPCR). Spearman's correlation coefficient was used to evaluate the correlations of Foxp1 mRNA expression with QMGs and serum acetylcholine receptor (AchR) antibody concentration in all subjects. Results:In the 26 MG patients, there were 10 with ocular MG and 16 with general MG; 7 patients were with thymoma, 2 were with thymic hyperplasia, and 17 were with normal thymus. The Foxp1 mRNA expression in CD4 +T cells of MG patients (0.692±0.257) was significantly decreased as compared with that in the heathy controls (1.051±0.364, P<0.05). Moreover, the Foxp1 mRNA expression in general MG patients was significantly lower than that in ocular MG patients ( P<0.05). The Foxp1 mRNA expression in MG patients 6 months after acrolimus monotherapy was significantly increased as compared with that before treatment ( P<0.05). There was a negative correlation between Foxp1 mRNA expression and QMGs ( r=-0.438, P=0.025). Conclusion:Transcript factor Foxp1 mRNA expression is downregulated in CD4 +T cells of MG patients, and its expression is negatively correlated with MG severity, which can reflect the effect of tacrolimus monotherapy on MG to some extent.
摘要
Inflammatory response is an important mechanism of secondary nerve injury in ischemic stroke, which is still a research hotspot in the field of neuroscience at present. Astrocytes are characterized by extensive distribution in brain, strong hypoxia tolerance, and the ability to interact with almost all cells in neurovascular unit, thus becoming potential therapeutic targets for alleviating ischemic injury. After ischemic stroke, astrocytes quickly become reactive astrocytes, releasing a large number of inflammatory cytokines, promoting the activation and invasion of other inflammatory cells, triggering a cascade of inflammatory responses, and aggravating ischemic injury. A variety of basic studies have shown that inhibiting the astrocytes activation and astrocytosis can significantly reduce neuroinflammatory response and infarct volume, and significantly improve the neurological function recovery in a model of middle cerebral artery occlusion. In this paper, the research progress of inflammatory response of astrocytes after ischemic stroke was reviewed from the aspects of astrocyte activation and polarization, release of inflammatory cytokines, interaction of inflammatory cells and corresponding targeted therapy strategies.

Objective@#To investigate the safety and efficacy of surgical treatment for chronic radiation intestinal injury.@*Methods@#A descriptive cohort study was performed. Clinical data of 73 patients with definite radiation history and diagnosed clinically as chronic radiation intestinal injury, undergoing operation at Department of Colorectal Surgery, the Sixth Affiliated Hospital of Sun Yat-sen University from January 1, 2012 to February 28, 2019, were reviewed and analyzed retrospectively. Patients did not undergo operation or only received adhesiolysis were excluded. All the patients had preoperative examination and overall evaluation of the disease. According to severity of intestinal obstruction and patients′ diet, corresponding nutritional support and conservative treatment were given. Surgical methods: The one-stage bowel resection and anastomosis was the first choice for surgical treatment of chronic radiation intestinal injury. Patients with poor nutritional condition were given enterostomy and postoperative enteral nutrition and second-stage stoma closure and intestinal anastomosis if nutritional condition improved. For those who were unable to perform stoma closure, a permanent stoma should be performed. Patients with severe abdominal adhesion which was difficult to separate, enterostomy or bypass surgery after adhesiolysis would be the surgical choice. For patients with tumor metastasis or recurrence, enterostomy or bypass surgery should be selected. Observation parameters: the overall and major (Clavien-Dindo grades III to V) postoperative complication within 30 days after surgery or during hospitalization; mortality within postoperative 30 days; postoperative hospital stay; time to postoperative recovery of enteral nutrition; time to removal of drainage tube.@*Results@#Of the 73 patients who had been enrolled in this study, 10 were male and 63 were female with median age of 54 (range, 34-80) years. Preoperative evaluation showed that 61 patients had intestinal stenosis, 63 had intestinal obstruction, 11 had intestinal perforation, 20 had intestinal fistula, 3 had intestinal bleeding, and 6 had abdominal abscess, of whom 64(87.7%) patients had multiple complications. Tumor recurrence or metastasis was found in 15 patients. A total of 65(89.0%) patients received preoperative nutritional support, of whom 35 received total parenteral nutrition and 30 received partial parenteral nutrition. The median preoperative nutritional support duration was 8.5 (range, 6.0-16.2) days. The rate of one-stage intestine resection was 69.9% (51/73), and one-stage enterostomy was 23.3% (17/73). In the 51 patients undergoing bowel resection, the average length of resected bowel was (50.3±49.1) cm. Among the 45 patients with intestinal anastomosis, 4 underwent manual anastomosis and 41 underwent stapled anastomosis; 36 underwent side-to-side anastomosis, 5 underwent end-to-side anastomosis, and 4 underwent end-to-end anastomosis. Eighty postoperative complications occurred in 39 patients and the overall postoperative complication rate was 53.4% (39/73), including 39 moderate to severe complications (Clavien-Dindo grade III-V) in 20 patients (27.4%, 20/73) and postoperative anastomotic leakage in 2 patients (2.7%, 2/73). The mortality within postoperative 30 days was 2.7% (2/73); both patients died of abdominal infection, septic shock, and multiple organ failure caused by anastomotic leakage. The median postoperative hospital stay was 13 (11, 23) days, the postoperative enteral nutrition time was (7.2±6.9) days and the postoperative drainage tube removal time was (6.3±4.2) days.@*Conclusions@#Surgical treatment, especially one-stage anastomosis, is safe and feasible for chronic radiation intestine injury. Defining the extent of bowel resection, rational selection of the anatomic position of the anastomosis and perioperative nutritional support treatment are the key to reduce postoperative complications.

The surgical treatment of low rectal diseases has gradually changed from open radical operation to endoscopic minimally invasive operation. Transanal total mesorectal excision (taTME) combines endoscopic technique with transanal approach, and solves the problem of surgery exposure in lower rectal cancer. It has become an option for colorectal surgeons in lower rectal cancer. We named this operation as transanal endoscopic surgery, for the appropriateness when it is applied for other colorectal diseases. Transanal endoscopic surgery belongs to the category of natural orifice transluminal endoscopic surgery, which achieves the same pathological outcomes with less invasiveness and better organ functions compared with traditional surgery. It represents the tendency of low rectal surgery.

<p><b>OBJECTIVE</b>To explore the feasibility and clinical significance of precision low inferior mesenteric artery (IMA) ligation with the left colonic artery (LCA) preservation and root lymph node dissection in laparoscopic radical resection for rectal cancer, according to the inferior mesenteric artery (IMA) types.</p><p><b>METHODS</b>One Hundred and fore cases of rectal cancer patients who underwent laparoscopic resection in The Sixth Affiliated Hospital of Sun Yat-sen University from October 2015 to June 2016 were selected and divided into study group and control group according to different surgical methods. The study group (52 cases) accepted precision low IMA ligation with the LCA preservation and root lymph node (No.253) dissection, according to the IMA types and length examined by preoperative computed tomography angiography (CTA) reconstruction. The control group (52 cases) accepted the traditional high IMA ligation. The perioperative efficacy indexes and postoperative recovery situation of the two groups were compared.</p><p><b>RESULTS</b>The IMA types, IMA length and preoperative clinical stages were not significantly different between the two groups (all P>0.05). The surgery was completed smoothly for patients in both groups, with no conversion to open surgery. But two patients in the study group underwent left colonic artery ligation for intra-operative need. There were no significant differences in the operative time, intra-operative blood lose, the rate of protective ileostomy and post-operative pathological stages between the two groups (all P>0.05). More total lymph nodes [(24.9±5.7) vs. (16.9±4.2), P=0.001] and No.253 lymph nodes [(2.4±1.1) vs. (1.5±0.8), P=0.001] were harvested in study group as compared to control group. However, the positive rate of total harvested lymph nodes and No.253 lymph nodes between the two groups were not significantly different (P>0.05). There were no significant differences between the two groups in postoperative first anal exhaust time, postoperative hospital stay, total volume of postoperative intraperitoneal drainage, postoperative abdominal drainage tube retention time, postoperative anal drainage tube retention time and postoperative catheter retention time (All P>0.05). There were 2 cases of postoperative dysuria and 1 case of anastomotic bleeding in study group. There were 3 cases of postoperative dysuria and 2 cases of anastomotic leak in control group. Less postoperative complications (5.8% vs. 9.6%, P<0.05) in study group as compared to control group. There was no rehospitalization or death case in two groups within 30 days after operation.</p><p><b>CONCLUSIONS</b>In the laparoscopic radical resection of rectal cancer, preserving LCA and cleaning the root lymph nodes according to IMA types, which could increase the number of harvested lymph nodes and reduce the postoperative complications was safe and effective.</p>
摘要
Chronic radiation proctopathy (CRP) is the delayed adverse effect after radiotherapy for pelvic malignancies. It is characterized as progressive fibrosis in pathology. The symptoms are usually unspecific which include rectal bleeding, perianal pain, tenesmus, stool frequencies and so on. The course of CRP can present from months to years after radiation. Severe complications can occur in the late stage and will greatly affect the quality of life. Currently, there is no standard guides for diagnosis and treatment of CRP. For advancing the knowledge and proposing new treatment modalities of CRP, this article summarizes our 10-year experience as follows: (1) Except the existence of vessel damage, interstitial fibrosis, mucous ulcer, edema and inflammatory cell infiltration in the radiation-injury area, the capillary count was obviously reduced in mucous substratum and angiostatin expression up-regulated remarkably in above area, resulting in the continuous development of compensatory capillary expansion and interstitial fibrosis in mucous layer. (2) Rectal ultrasound examination was used the first time to diagnose CRP. According to thickness change of rectal wall layer and increase of blood signal, severity of CRP activity was evaluated with good diagnostic value. (3) For slight-moderate rectal bleeding, moderate-heavy bleeding and heavy bleeding, application of retention enema with compound preparation based on mucoprotective agents, regional perfusion hemostasis with formaldehyde and proximal colostomy gained satisfactory efficacy. (4) Improved Parks operation should be recommended for CRP patients with advanced complications. (5) For rectal cancer patients receiving neoadjuvant chemoradiotherapy, "proximal extended excision" should be performed innovatively to decrease the risk of anastomotic complications (Tianhe Procedure).
