Insulin secretion and insulin resistance were evaluated in 152 subjects with normal glucose tolerance, impaired fasting glucose (IFG) and (or) impaired glucose tolerance (IGT). The data showed that subjects with IGT exhibited an evident deficit in the early and late phases of insulin secretion after glucose load and mild insulin resistance, and subjects with IFG demostrated evident insulin resistant and a great decline in early phase insulin response and HOMA-β.

Objective:To investigate the complications of spastic cerebral palsy with selective posterior rhizotomy (SPR).Methods:In the study, 2 593 patients who had undergone SPR from January 2000 to September 2012 were followed-up for at least one year .The complications were classified .Results:Peri-operative complications:pulmonary system complications including bronchial spasm (5 cases, 0.19%) and aspiration pneumonia (4 cases, 0.15%);digestive system complications including abdominal bloa-ting (145 cases, 5.6%) and colic (80 cases, 3.1%);urinary system complications including tempora-ry bladder dysfunction (54 cases, 2.1%) and urinary tract infection (6 cases, 0.23%); peripheral nervous system complications including lower extremity weakness ( 327 cases, 12.6%) and lower extremity sensory disturbances ( 140 cases, 5.4%); central nervous system complications including headache (112 cases, 4.3%) and epileptic seizures (4 cases, 0.15%).None spinal or intracranial in-fection, intraspinal hematoma or intracranial hemorrhage were identified .General surgery complications including back pain (1 382 cases, 53.3%), delay wound healing caused by infection (5 cases, 0.19%) and cerebrospinal fluid leakage (8 cases, 0.31%).Long-term follow-up complications inclu-ding lower limb decreased exercise capacity ( incidence: 7.33%) and lower extremity sensory distur-bance (incidence:5.59%).Urination occurred in only one case and defecation function disturbance with no sexual dysfunction was identified .The incidences of scoliosis , thoracic kyphosis , spondylolisthe-sis and long-term back pain were 7.23%(31/429), 4.2%(18/429), 10.49%(45/429) and 9.72%respectively .Conclusion:SPR is one of the effective and safe surgical treatments for spastic cerebral pal-sy.Valid methods should be applied to reduce the incidence of postoperative complications , such as choosing the appropriate patients , meticulously operating in the surgery , assistance of electrophysiological guidance , reinforcing perioperative management and regular rehabilitation training after operation .

Objective To investigate the promotion effect of Danhong injection (DH) on brain-derived neurotrophic factor (BDNF) expression in Schwann cells (SCs) of SD rats.Methods In experiment of SCs apoptosis induced by advanced glycation end products (AGEs),SCs were divided into control group,AGEs treatment group and DH+AGEs treatment group; 48 h after each treatment,the SCs count was compared.In experiment of DH affecting mRNA and protein BDNF expressions in SCs,real time-PCR and Western blotting were used.In the experiment of DH combined with different inhibitors (Calphostin C,LY294002,H89,U0126,FR180204 and SB203580) affecting mRNA BDNF expression in SCs,real time-PCR was used.Results The number of SCs in AGEs treatment group was significantly decreased than that in the control group,but that in DH+AGEs treatment group was statistically increased than that in AGEs group (P＜0.05).The mRNA and protein expressions of BDNF in the DH treatment group were significantly increased than those in the control group (P＜0.05).As compared with DH group,DH+Calphostin C treatment group had significantly decreased BDNF mRNA expression (P＜0.05); BDNF mRNA expression in the DH+U0126,DH+FR180204 and DH+SB203580 treatment groups was significantly decreased as compared with that in the DH treatment group (P＜0.05).Conclusions DH could effectively inhibit SCs apoptosis induced by AGEs and significantly promote BDNF expression;protein kinase C (Calphostin C) and mehtyl ethyl ketone (U0126)/extracellular regulated protein kinases (FR180204EK)/p38 (SB203580) may be the important signaling transconduction pathways for BDNF expression.

Objective:To study the efficiency and safety of domestic Remebot robot (neurosurgical positioning and navigation system) in the resection of craniocerebral microlesions and functional area lesions.Methods:Twelve patients accepted resection of craniocerebral microlesions and functional area lesions in our hospital from October 2021 to March 2022 were chosen in our study; navigation, localization and resection of craniocerebral microlesions and functional area lesions were performed with assistance of Remebot robot. Surface Markers were used for optical registration during the surgery, and the registration error was recorded in detail. Scalp incision and bone flap boundary were designed by laser navigation. Postoperative head CT and MRI scan were performed to observe intracranial hemorrhage and lesion resection. The postoperative image was fused with the preoperative surgical plan to calculate the deviation between the planned and actual flap centers.Results:The patient registration error was 0.6-1.5 mm, with an average of (0.9±0.12) mm. The registration error of the manipulator was 0.09-0.12 mm. Preoperative and postoperative image fusion showed that the deviation between the planned and actual flap centers was 1.4-4.5 mm, with an average of (1.9±1.1) mm. All surgical procedures were performed with robot laser navigation to find the lesion boundary along the planned path at one time, which was less destructive to the cortex and surrounding tissues. Postoperative head CT or MRI examination showed that all lesions were completely resected. No serious complications occurred in these 12 patients.Conclusion:Domestic robot can provide precise localization and navigation function for the resection of craniocerebral microlesions and functional area lesions, improving the surgical efficiency and ensuring the safety of surgery.

Objective:To understand the current status of mental resilience of patients undergoing hysteroscopy and its influencing factors so as to provide guidance for clinical health education.Methods:By the convenient sampling method, patients who underwent hysteroscopy in the gynecological clinic in a ClassⅢGradeA hospital in Jiaozuo from January to June 2019 were selected as research objects. Connor-Davidson Resilience Scale (CD-RISC) , Perceived Social Support Scale (PSSS) and General Data Questionnaires were used to conduct survey to explore the current status of mental resilience of patients undergoing hysteroscopy and its influencing factors. This study retrieved 157 valid questionnaires.Results:The score of CD-RISC in 157 patients undergoing hysteroscopy was (58.20±27.45) , with a minimum of 16 points and a maximum of 107 points. There were statistically significant differences in the total scores of CD-RISC among patients of different ages, education background and residential area who underwent hysteroscopy ( P<0.05) . The correlation analysis showed that the level of mental resilience of patients undergoing hysteroscopy was positively correlated with the score of social support ( P<0.05) . Multiple linear regression analysis showed that age, education background, living area, family support were the main factors influencing the mental resilience of patients undergoing hysteroscopy ( P<0.05) . Conclusions:The mental resilience of patients undergoing hysteroscopy is relatively poor. Age of patients, educational background of patients, living area, family support are the important factors affecting mental resilience. Targeted disease education and psychological counseling should be carried out for different groups. Multiple channels and diversified ways should be adopted to strengthen social support so as to improve mental resilience of patients, enable them to cope with the disease in a positive way and promote recovery.

Objective:To summarize the clinical characteristics of adenovirus (HAdVs) pneumonia in children.Methods:The clinical manifestations, laboratory results, imaging features and treatment courses of 541 children with HAdVs pneumonia treated in Shenzhen Children′s Hospital from January 2017 to August 2019 were retrospectively studied.Results:The number of children diagnosed with HAdVs pneumonia increased year by year.A total of 541 patients were included in this study (214 females and 327 males, median age 31 months). The majority of patients (89.3%, 483/541 cases) were less than 6 years of age.Cough (98.3%, 532/541 cases) was the most common symptom, followed by fever (93.7%, 507/541 cases), tachypnea (36.6%, 198/541 cases) and wheeting (32.5%, 176/541 cases). Thirteen point three percent patients (72/541 cases) had existing primary diseases.Severe HAdVs pneumonia was observed in 33.8% of patients (183/541 cases), the most common intrapulmonary complication were pleural effusion(18.6%, 101/541 cases) and respiratory failure (7.0%, 38/541 cases). In co-infection cases, 46.9% of the patients (254/541 cases) suffered from co-infection with mycoplasma pneumoniae, 21.6% of the patients (117/541 cases) suffered from bacterial co-infection.Ninety-eight point five percent of the patients (533/541 cases) were cured, and 1.5% of the patients (8/541 cases) died or discharged voluntarily.Convulsions [ P=0.026, OR=7.312 (95% CI: 1.267-42.191)] and bacterial co-infections [ P=0.030, OR=2.724 (95% CI: 1.101-6.741)] were independently correlated with the occurrence of severe HAdVs pneumonia. Conclusions:Pre-school aged children are at higher risks of developing HAdVs pneumonia.The majority of patients presents with fever and cough as primary manifestations.Tachypnea and wheezing are also common clinical features of HAdVs pneumonia patients.Approximately a third of children with HAdVs pneumonia may develop into severe pneumonia.The presentation of convulsion and the exis-tence of bacterial co-infections may help to predict the development of severe HAdVs pneumonia in pediatric patients.
