Objective To explore the efficacy of bilateral facial muscle training combined with visual electromyography biofeedback on facial nerve function recovery in patients with idiopathic facial nerve palsy. Methods Patients with idiopathic facial nerve palsy admitted to Shanghai Fifth People’s Hospital, Fudan University from July 2022 to July 2024 were selected and randomly divided into a control group and an intervention group. The control group received conventional physical factor therapy, while the intervention group received bilateral facial muscle training combined with visual electromyography biofeedback therapy based on the control group’s regimen. After 20 treatment sessions, the total effective rate, the House-Brackmann (H-B) facial nerve grading system, the Sunnybrook Facial Grading System (SFGS) score, and the average value ratio of maximal amplitudes of bilateral frontalis and zygomaticus muscles were compared between the two groups. Results A total of 90 patients were included, 45 in each group. After 20 treatment sessions, the total effective rate was significantly higher in the intervention group than in the control group (84.4% vs 75.6%, P＝0.003). Compared with the control group, the intervention group demonstrated a significantly lower H-B grade (P＝0.003) and a higher SFGS score (P＝0.001). The average value ratios of maximal amplitudes of the affected versus healthy side frontalis (P＝0.013) and zygomatic (P＝0.022) muscles were higher in the intervention group than in the control group. Conclusions Bilateral facial muscle training combined with visual electromyography biofeedback is an effective approach for treating idiopathic facial nerve palsy, effectively promoting the recovery of facial nerve function, and improving facial symmetry and facial muscle function.

Objective:To investigate the impact of circumferential tumor location (anterior wall, nonanterior wall, or circumferential) on circumferential resection margin (CRM) status, local recurrence, and survival in patients with mid-low rectal cancer.Methods:A retrospective cohort study was conducted using data from 696 patients with mid-low rectal adenocarcinoma who underwent surgery in the Department of Colorectal Surgery at the First Affiliated Hospital of Naval Medical University between December, 2018 and December, 2019. Based on MRI or contrast-enhanced CT findings, the rectal wall was divided into four quadrants: anterior, posterior, left, and right. Tumors were classified into three groups: anterior wall group ( n = 245), nonanterior wall group ( n = 286, tumors predominantly located on the posterior or lateral walls), and circumferential group ( n = 165, tumors involving ≥ 3/4 of the circumference). Propensity score matching (PSM) was used to balance baseline characteristics. Outcomes included pathological CRM positivity, local recurrence rate (LRR), overall survival (OS), and disease-free survival (DFS). Cox regression analysis was performed to identify risk factors for recurrence, and subgroup analysis was conducted in patients who did not receive neoadjuvant therapy. Results:After PSM, both the anterior and circumferential groups had significantly higher pathological CRM positivity rates compared to the nonanterior wall group ( P=0.040 and P=0.039, respectively). The median follow-up time was 64 months (range: 1-71 months). Compared to the nonanterior wall group, the anterior wall group also had a significantly higher 5-year LRR (8.8% vs. 2.3%, P=0.003), and significantly lower 5-year OS (80.7% vs. 91.6%, P=0.001) and DFS (76.6% vs. 84.6%, P=0.029). The circumferential group had a significantly higher 5-year LRR than the nonanterior wall group (11.4% vs. 3.8%, P=0.020), but no significant differences were observed in 5-year OS (81.8% vs. 89.5%, P=0.100) or DFS (70.7% vs. 78.3%, P=0.101). No significant differences were found between the anterior and circumferential groups in 5-year LRR (11.1% vs. 9.7%), OS (76.3% vs. 83.7%), or DFS (69.8% vs. 74.1%) either (all P>0.05). Cox univariate analysis and multivariate analysis identified anterior wall tumors (HR=3.751, 95%CI: 1.373-10.215, P=0.010), circumferential tumors (HR=3.240, 95%CI: 1.109-9.466, P=0.032), pathological CRM positivity (HR=3.071, 95%CI: 1.144-8.245, P=0.026), and lymph node metastasis (HR=2.584, 95%CI: 1.192-5.601, P=0.016) as independent risk factors for LRR. Conversely, a greater distance from tumor to the anal verge (per 1 cm increase, HR=0.831, 95%CI: 0.712-0.970, P=0.019), and neoadjuvant therapy (HR=0.442, 95%CI: 0.204-0.957, P=0.038) were identified as independent protective factors against LRR. In patients who did not receive neoadjuvant therapy, locally advanced nonanterior wall tumors exhibited markedly low LRR (1.3% for pathological stage II-III, 1.6% for pT3-4 stage). Conclusion:Rectal tumors located in the anterior wall or involving the circumference are associated with higher CRM positivity rates, increased local recurrence, and poorer survival. These patients should be prioritized for neoadjuvant therapy. In contrast, nonanterior wall tumors have a low recurrence rate, and selective omission of neoadjuvant therapy may be considered for these cases.

Objective:To introduce the method of using anal fistula endoscope to treat chronic sinus tract leakage at rectal anastomosis site.Methods:We used anal fistula endoscopy to treat a patient with chronic sinus tract leakage after radical resection of rectal cancer, mainly including the following 5 steps: (1) establishing a water injection circulation system through the anus; (2) scraping off purulent coating and mucosa on the surface of the sinus tract with the brush; (3) hemostasis and removal of necrotic tissue with electrocoagulation rods; (4) filling the sinus tract with bioprotein gel; (5) compressing the sinus tract with transanal drainage tube.Results:The patient is a 70 year old male with rectal cancer. After undergoing 3D laparoscopic assisted radical resection of rectal cancer via abdominal anterior resection (Dixon's procedure) and diverting ileostomy surgery for more than 3 months, leakage of the rectal anastomosis was found through colonoscopy and anal iodine water contrast imaging .The patient started eating and flowing juice 6 hours after surgery, got out of bed 24 hours after surgery, and was discharged 48 hours after the removal of the anal canal. Three months after surgery, colonoscopy and transanal iodine hydrography showed that the sinus repair was intact. The diverting ileostomy was reduced 4 months after surgery.Conclusion:Anal fistula endoscope is safe and feasible for the treatment of chronic sinus tract anastomotic leakage in selected patients.

Objective To investigate the effect of Shenqi Dihuang decoction combined with recombinant erythropoietin and L-carnitine on renal function in patients with end-stage renal disease and the regulation of Janus activated kinase/signal transducer and activator of transcriptions(JAK/STAT)pathway.Methods A total of 144 patients with end-stage renal disease who were treated in the Second Affiliated Hospital of Xingtai Medical College from October 2019 to October 2021 were selected as the study objects.Patients were divided into Shenqi Dihuang decoction treatment group and conventional treatment group according to random number table method,72 cases in each group.Maintenance hemodialysis was performed in both groups.The conventional treatment group received recombinant erythropoietin and L-carnitine,while the Shenqi Dihuang decoction treatment group had Shenqi Dihuang decoction(prescription composition:30 g each of raw Astragalus,Parasitic loranthus,Eclipta,Polyporus,Poria bark,Raw coix seed,Salvia miltiorrhiza,and Pyrrosia,15 g each of Codonopsis pilosula,Dogwood,Herba lycopi,and Common yam rhizome,10 g each of raw Rehmannia glutinosa,Litchi core,Silkworm sand and Curcuma zedoary,6 g Cassia seed),once a day for 3 months.The clinical efficacy,renal function,microinflammatory status and serum JAK/STAT pathway related protein levels were observed after treatment in two groups of patients with different treatment modalities,and the occurrence of adverse reactions was recorded.Results The total effective rate of Shenqi Dihuang decoction was higher than that of conventional treatment group[90.28%(64/72)vs.77.78%(55/72),P<0.05].After treatment,the residual renal function(RRF),24-hour urine protein,blood urea nitrogen(BUN),blood creatinine(SCr)and inflammatory factors[hypersensitive C-reactive protein(hs-CRP),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)]were lower than before treatment,the post-treatment RRF of the Shenqi Dihuang decoction treatment group was higher than that of the conventional treatment group(mL/min:4.82±1.18 vs.3.96±1.05),while 24 hours urine protein(mg:62.26±12.16 vs.97.71±16.28),BUN(mmol/L:16.25±3.64 vs.20.65±4.13),SCr(μmol/L:242.25±25.62 vs.280.62±26.63),hs-CRP(mg/L:5.86±1.15 vs.7.78±1.32),IL-6(ng/L:3.26±0.64 vs.4.62±1.13)and TNF-α(μg/L:29.23±5.64 vs.32.66±6.13)were significantly lower than those in the conventional treatment group(all P<0.05).After treatment,JAK and STAT in Shenqi Dihuang decoction group were increased compared with before treatment,phosphorylated JAK(p-JAK)and phosphorylated STAT(p-STAT)were decreased compared with before treatment(both P<0.05),while the serum JAK/STAT pathway related protein levels in conventional treatment group were not significantly changed(all P>0.05).Therefore,JAK and STAT in the Shenqi Dihuang decoction treatment group after treatment were significantly higher than those in the conventional treatment group[JAK(μg/L):1.46±0.28 vs.1.26±0.26,STAT(μg/L):1.37±0.25 vs.0.99±0.24,both P<0.05],p-JAK and p-STAT were significantly lower than those in the conventional treatment group[p-JAK(μg/L):0.45±0.08 vs.0.65±0.13,p-STAT(μg/L):0.66±0.13 vs.0.82±0.28,both P<0.05].There was no statistically significant difference in the incidence of adverse reactions between the two groups[13.88%(10/72)vs.9.72%(7/72),P>0.05].Conclusion Taking Shenqi Dihuang decoction based on recombinant erythropoietin and L-carnitine treatment can effectively inhibit the JAK/STAT signaling pathway,and improve renal function and micro-inflammatory status in patients with end-stage renal disease,thereby improving the therapeutic effect.

Cognitive dysfunction refers to dysfunction of individual perception,memory,understanding,learning,creation and other dysfunctions caused by abnormal brain function and structure.Based on the fact that the spleen can't regulate transportation and transformation,govern blood and send up essential substance,combined with the microbiota-gut-brain axis,this article discussed the etiology and pathogenesis of intestinal flora imbalance affecting cognitive dysfunction in TCM.It was proposed that the spleen in TCM and intestinal flora are connected in physiology and pathology:the spleen regulates spirit and governs cognition,when the spleen fails to function normally that it can't dominate transportation and transformation,govern blood and send up essential substance will cause that the brain spirit can not be nourished;intestinal flora is closely related to the spleen in TCM,and affects brain function through the nervous system,endocrine,immune and metabolic mechanisms.This article can provide explore new ideas for the clinical research and treatment of cognitive dysfunction of traditional Chinese and Western medicine.

The Clinical Medicine Proficiency Test developed by the National Medical Examination Center of China in 2020 aims to assess whether clinical medical students possess the necessary medical humanities and basic medical theoretical knowledge and skills required for clinical internships. Since 2002, Japan has implemented the pre-clinical clerkship objective structured clinical examination and computer-based testing, which share similarities with China's proficiency test in terms of examination objectives, content, format, and score evaluation. Through comparing the examinations of China and Japan, this article concludes that it is necessary to learn from Japan's experience to expedite the process of promoting the Clinical Medicine Proficiency Test as an industry admission examination in China. We suggest that medical schools should keep tracking the development of the proficiency test and fully leverage its role in urging students to pay more attention to clinical internships. We also urge medical schools to establish a three-level examination system based on post competency criteria in line with the standards of the National Medical Licensing Examination to improve the quality of medical education.

In this paper， we systematically sorted out and verified the name， origin， producing area change， quality， efficacy and processing of Halloysitum Rubrum by consulting materia medica， medical books， prescription books from past dynasties， and modern literature， and combined with the comprehensive analysis of trait identification， hygroscopicity measurement and X-ray diffraction（XRD） detection， in order to provide a basis for understanding the original source of the mineral medicine. The results indicated that Halloysitum Rubrum was first contained in the Shennong Bencaojing， it had been consistently named Chishizhi， there were also aliases such as Chifu， Hongxinshi and Chiyouzhi. The description of Halloysitum Rubrum in ancient materia medica aligns with modern findings， categorizing it under the silicate kaolinite family， specifically polyhydrous kaolinite， with associated minerals mainly being dickite， nacrite， hematite， gibbsite， mica， etc. Historically， the production area of Halloysitum Rubrum was mainly located in the Qinling Mountains， Shandong and Henan， and is now primarily distributed in most parts of China， including Henan， Hubei and other provinces. Quality evaluation in ancient times included descriptions like "fresh and greasy color"， "delicately sticky tongue and lips" and "smooth as fat". Modern materia medica mostly evaluates its quality based on color， luster， texture and hygroscopicity， noting characteristics such as red color， smoothness， delicacy， softness and strong viscosity. Halloysitum Rubrum is sweet， sour and pungent in flavor， warm in nature， non-toxic， and belongs to the heart and large intestine meridians. It acts as an astringent and solidifying agent， particularly useful in the treatment of long-term dysentery and diarrhea， common processing methods include fire calcination， water flying， and vinegar quenching. Comprehensive analysis of the traits， XRD and humidity absorption of different batches of samples showed that the commercially available Halloysitum Rubrum is mainly bright red or brownish red， with a smooth surface like grease， soft and smooth texture， delicate cross-sectional texture， and some have waxy luster and strong water absorption. It is mainly composed of 10 Å（1 Å=0.1 nm） polyhydric kaolinite， and is often accompanied by 7 Å polyhydric kaolinite， nacrite， etc. Genuine products tend to have higher moisture absorption than counterfeit ones， which can be used as a key indicator to distinguish the authenticity. The quality evaluation of Halloysitum Rubrum aligns with historical materia medica， where "fresh color， delicate and greasy lips" could serve as a key feature for its quality evaluation.

Stage T4 colon cancer is divided into two categories:tumor penetrating the visceral peritoneum(T4a)and tumor directly invading or attaching to adjacent organs or structures(T4b).Treatment of T4 colon cancer requires technically demanding surgical procedures,including total resection of adjacent infiltrating organs or structures,and is characterized by a high incidence of postoperative complications and a high rate of positive surgical margin microscopy.It has been found that taking laparoscopic surgery for T4 colon cancer may decrease long-term survival and increase the rate of peritoneal metastasis,but taking laparoscopic surgery for colon cancer also has the potential advantages in increasing perioperative benefits and improving the prognosis.With the upgrade of laparoscopic equipment and the improvement of surgeons'surgical skills,more and more surgeons have adopted laparoscopic surgery to treat T4 colon cancer.Currently,the oncologic safety of laparoscopic surgery for T4 colon cancer has not been effectively evaluated.Therefore,this article reviews the advantages,risks,and the choice of treatment strategies for laparoscopic surgery for T4 colon cancer,taking into account the current status and progress of domestic and international studies.
