Sensory dysfunction is a common clinical problem for children with cerebral palsy.Proprioception plays a key role in maintaining postural adjustment and balance coordination, so proprioceptive assessment is of great significance for further rehabilitation of children with cerebral palsy.At present, proprioception assessment is mainly used in adults such as stroke and joint injury, but there is still a lack of research in children, especially in children with cerebral palsy.Therefore, this paper aims to review the evaluation of proprioception of children with cerebral palsy at home and abroad.

Objective To explore the value of preoperative detection of soluble fragments of cytokeratin-19 (CYFRA21-1), carcinoembryonic antigen (CEA), and postoperative detection of nuclear proliferation associated antigen Ki67 in prognostic evaluation of non-small cell lung cancer patients. Methods The clinicopathological data and follow-up results of patients with non-small cell lung cancer treated in the Department of Thoracic Surgery of the First Affiliated Hospital of Xiamen University in 2017 were collected. CYFRA21-1>3.39 ng/mL was defined as positive, and CEA>5 ng/mL was defined as positive. The receiver operating characteristic curve (ROC curve) of Ki67 expression level was drawn. The maximum area under the curve (AUC) was the cutoff value of Ki67 expression level, and the Ki67 expression level greater than its cutoff value was defined as positive. Cox regression analysis was used to determine the independent risk factors for poor prognosis in patients with non-small cell lung cancer. Results Finally 248 patients were collected, including 125 males and 123 females, with a median age of 61 years (ranging from 30 to 81 years) at the time of surgery. Univariate analysis showed that positive CYFRA21-1, high expression of Ki67, positive CEA, age≥60 years at operation, distant metastasis, lymph node metastasis, maximum tumor diameter>3 cm, and TNM stage Ⅲ were associated with poor prognosis in patients with non-small cell lung cancer. When combined detection of preoperative tumor markers and postoperative Ki67, the prognosis of all negative patients was the best, and that of all positive patients was the worst. Cox regression analysis showed that positive CEA+positive CYFRA21-1+high expression of Ki67 was an independent risk factor for poor prognosis in patients with non-small cell lung cancer (P<0.05). Conclusion The combined detection of preoperative serum CYFRA21-1, CEA, and postoperative Ki67 has important value in evaluating the prognosis of non-small cell lung cancer patients.

Objective To investigate the mechanism of inducing macrophage polarization induced by acupoint effect of electroacupuncture to promote the repair of acute skeletal muscle injury.Methods 45 SD rats were randomly divided into blank group,model group,electroacupuncture group(EA group),sodium chrominate group (DSCG group) and electroacupuncture+sodium chrominate group (hereinafter referred to as EA+DSCG group),with 9 rats in each group. The rats in the EA group and the EA+DSCG group were subjected to EA intervention at the right "Chengshan" (BL57) and "Yanglingquan"(GB34),with a frequency of 2 Hz/100 Hz. The gait changes of rats were recorded by animal gait analyzer. The morphological changes of the right gastrocnemius were observed by HE staining. The changes of mast cell aggregation and degranulation in local skin muscles of "chengshan" point were observed by toluidine blue staining. The expressions of Pax7,MyoD and skin mast cells and 5-HT in the right gastrocnemius were detected by immunofluorescence method. The positive expressions of CD68 and CD206 in right gastrocnemius macrophage was observed by immunohistochemical staining.Results Compared with blank group,the wiggle time of the right hind leg in model group and DSCG group increased,stride length decreased,HE staining showed inflammatory cell infiltration,myocyte enlargement,degeneration and necrosis. The degranulation rate of local skin mast cells in "Chengshan" (BL57) area increased,and the expressions of mast cell tryptase,5-HT,Pax7,MyoD,CD68 and CD206 increased (P<0.05). Compared with model group,the wiggle time of the right hind leg in EA group and EA+DSCG group decreased,stride length increased,HE staining showed that inflammatory cell infiltration was reduced,muscle cells were uniform in size and arranged neatly. Mast cell degranulation rate increased significantly in EA group,and the expressions of mast cell tryptase,5-HT,Pax7,MyoD and CD206 increased (P<0.05),while CD68 expression decreased (P<0.05). Compared with EA+DSCG group,the degranulation rate of mast cells and the expressions of mast cell tryptase,5-HT,Pax7,MyoD and CD206 increased (P<0.05),while CD68 expression decreased in EA group (P<0.05). Conclusion EA "Chengshan" (BL57) and "Yanglingquan" (GB34) can stimulate acupuncture points to locally induce mast cell degranulation,promote the polarization of macrophages,and then activate muscle satellite cells to play the regulatory process of repairing skeletal muscle injury.

For muscle-invasive bladder cancer (MIBC) patients, preoperative neoadjuvant chemotherapy (NAC) can reduce the tumor stage, treat micrometastases, prolong the median survival, and improve the prognosis.However, NAC is associated with side effects such as renal impairment, thromboembolism and drug toxicity.NAC itself suffers from deficiencies such as renal function impairment, thromboembolism, and drug toxicity.Its therapeutic efficacy is affected by factors such as tumor pathology type, DNA repair gene defects, whether it is primary MIBC, and TNM staging, so there are certain limitations in its use.Based on the cisplatin treatment regimen, more and more studies are exploring the limitations and shortcomings of NAC in MIBC treatment regimen.Therefore, this paper provides an overview and outlook of the application of NAC in MIBC treatment.

Objective To evaluate the value of intrathecal synthetic related markers in patients with mild cognitive impairment(MCI),Alzheimer's disease(AD),and other types of dementia.Methods Retrospec-tively collect the clinical data of 577 patients diagnosed with MCI(MCI group,178 cases),AD(AD group,131 cases),and other types of dementia(other types group,268 cases)from June 2019 to July 2023 in Beijing Tiantan Hospital,Capital Medical University.Oligoclonal zone electrophoresis(OCB)and 24 h intrathecal pro-tein synthesis rate(ISR)of each group were investigated,and the difference of different indexes among the groups was compared to evaluate the value of related indexes in the differential diagnosis of different diseases.Results Compared with AD group and other groups,AD group had a higher proportion of females,more patients were＞50-70 years old,and the incidence of abnormal lipid metabolism was higher,with statistical significance(P＜0.05).There were significant differences in OB(S),cerebrospinal fluid albumin,serum albumin and cerebrospinal flu-id IgG in different disease groups(P＜0.05).IgG index and ISR in patients with positive SOB(CSF)were higher than those in negative and weakly positive patients,and the differences were statistically significant(P＜0.001).IgG index was positively correlated with ISR(r=0.878,P＜0.001).Conclusion Intrathecal synthetic mark-ers such as IgG index,SOB(CSF)and 24 h ISR have synergistic effects in the diagnosis of cognitive dysfunction and various dementias,which can be collectively utilized in the diagnosis of diseases.

This article reports a case data of primary malignant melanoma of the penis admitted to the Affiliated Hospital of Qinghai University. A 56-year-old patient was admitted to the hospital 1 month after the discovery of a penile mass. Physical examination: An irregular cauliflower-like mass about 1.5 cm×2.0 cm in size was seen below the external urethral orifice, covered with yellow necrotic tissue, and tenderness was positive. Several nodes were palpable in the left and right groin areas, tenderness positive. Laboratory examination showed no abnormality. The CT examination of head, chest, abdomen and pelvis showed no obvious abnormality. The biopsy of the penile mass showed malignant melanoma of the penis. The pathological results of biopsy of the right inguinal lymph node considered local inflammation. Combined with the patient's medical history, physical examination, imaging examination and lymph node biopsy results, a diagnosis of primary penile malignant melanoma was made. Partial penile resection was performed, and the postoperative pathological diagnosis was malignant melanin invasion of the epidermis with ulceration. There was no local recurrence and metastasis during the 9-month follow-up.

In February 2022, the German Society of Pediatric and Adolescent Medicine published the first Evidence-based Recommendations for the Treatment and Prevention of Non-specific Back Pain in Children and Adolescents, which provides clinical evidence and recommendations for the etiology, risk factors and diagnosis of back pain in children and adolescents, and the treatment and prevention suggestions on the non-specific back pain.Although the guideline for the diagnosis and treatment of non-specific low back pain have been launched in China, a specific description of back pain in children and adolescents is lacking.With regard to increasing incidence of low back pain in children and adolescents, and differences in term of the etiology, risk factors, diagnosis and treatment of back pain between children-adolescents and adults, this article aims to interpret the guidelines to provide references and guidance for the clinical diagnosis and treatment of back pain in children and adolescents.

Objective:To evaluate the reliability and validity of the Chinese version of the Edinburgh visual gait score (EVGS-CN) for children with cerebral palsy.Methods:The EVGS-CN was established following international guidelines for translation and cross-cultural validation of health status questionnaires. Videos of 30 children with cerebral palsy were assessed independently by six raters (with different levels of experience in gait analysis) using the EVGS-CN. Inter- and intra- observer reliability were evaluated using intraclass correlation coefficients (ICCs). The correlation analysis and group comparison were used to test the technique′s criteria-related validity, convergent validity, and discriminant validity.Results:The ICC values of the 17 items in the EVGS-CN ranged from 0.20 to 0.87 for inter-observer reliability, and from 0.41 to 0.90 for intra-observer reliability. Most items showed good inter- and intra-observer reliability among experienced raters, but only a moderate level when used by inexperienced raters. The EVGS-CN results were strongly correlated with those of physician rating scale (PRS) ( r=0.77, P≤0.001) and observational gait scale (OGS) ( r=-0.85, P≤0.001), moderately correlated with the total gross motor function measure-D/E (GMFM-D/E) score ( r=-0.55, P≤0.01), and strongly correlated with 10MWT times ( r=-0.69, P≤0.001) and timed up and go (TUG) times ( r=0.60, P≤0.001). Moreover, significant differences in average EVGS score were found between different gross motor function classification system (GMFCS) levels and between affected limbs on different sides. Conclusion:The EVGS-CN demonstrates satisfactory reliability and validity in evaluating children with cerebral palsy when it is used by an experienced or inexperienced rater.

Objective:To explore the clinical effect of antibiotic bone cement combined with delayed lateral supramolleolar perforator fascial flap in the treatment of diabetic foot(DF).Methods:From April 2020 to July 2021, a total of 6 patients with DF were treated with antibiotic bone cement combined with delayed lateral supramolleolar perforator fascial flap. The patients were 5 males and 1 female, aged from 45 to 67 years old with an average of 56.2 years old. The wounds were all located in dorsal foot, 4 in right foot and 2 in the left. The wound area was 2.4 cm×5.0 cm-6.5 cm×10.0 cm. The depth of wound were: 3 cases up to tendon layer, and 3 cases up to metatarsal bone. Two of the wound were complicated with metatarsal osteomyelitis. The wounds at Wagner grade 3 in 4 patients and grade 4 in 2 patients. The flap size was 3.0 cm×6.0 cm-8.0 cm×11.0 cm. All of the wounds were repaired with delayed supramolleolar perforator fascia flap after debridement, application of antibiotic bone cement and fumigation with Sanhuang decoction(a traditional Chinese medicine). The affected limbs were externally fixed with plaster and raised after surgery, and the colour, temperature, tension and capillary reaction of the flaps were closely observed. Stitches were removed 2 weeks after surgery and rehabilitation of the affected limb was performed. Regular follow-up was made postoperatively. The appearance of flaps and the scar of donor and recipient sites were observed. The foot and ankle function were evaluated by the American Orthopaedic Association foot and Ankle Surgery(AOFAS) score scale.Results:Six cases of DF had no recurrence of wound infection. All flaps survived well. The average follow-up time was 6(3-14) months. The postoperative follow-up revealed satisfactory appearance of the flap, only linear scars remained in the donor and recipient sites. The function of foot and ankle recovered well with full weight-bearing and normal walk. AOFAS scores ranged from 81 to 95.Conclusion:It is an effective method to treat DF by applying antibiotic bone cement combined with delayed superior lateral malleolus perforator fascial flap. The operation is simple, safe and can cut down the time of treatment, quickly control the wound infection. It deserves further trials.
