OBJECTIVE To observe the effects of liraglutide on cardiovascular metabolism， left ventricular structure and function of non-alcoholic fatty liver disease （NAFLD） patients with type 2 diabetes mellitus （T2DM）. METHODS Totally 351 NAFLD patients with T2DM were enrolled retrospectively， who visited the Department of Endocrinology in our hospital from January 2019 to December 2022. They were divided into control group （196 cases） and observation group （155 cases） according to different treatment regimens. The control group received conventional standard treatment， and the observation group was additionally given Liraglutide injection 0.6 mg/d subcutaneously once a day based on the control group， adjusted to 1.2 mg/d after 7 days. Both groups received regular treatment for more than 12 months. The propensity matching method was used to match the two groups of patients at a ratio of 1∶1. The cardiovascular metabolism indexes and cardiac ultrasound parameters were compared， and the correlation between left ventricular structure， function parameters and cardiovascular metabolism indexes was analyzed. RESULTS After propensity score matching， there was no significant difference in baseline clinical data between the two groups （each 155 cases） before treatment （P＞0.05）. After 12 months of treatment， the waist circumference， weight， body mass index （BMI）， systolic blood pressure （SBP）， fasting blood glucose （FBG）， glycosylated hemoglobin （HbA1c） and triglyceride （TG） of both groups， as well as the diastolic blood pressure （DBP）， total cholesterol （TC）， uric acid （UA） and left ventricular mass （LVM） of the observation group， exhibited a significant decrease compared to pre-treatment levels （P＜0.05）. The high-density lipoprotein cholesterol （HDL-C）， estimated glomerular filtration rate （eGFR）， and E/A ratio in both groups， as well as the aspartate aminotransferase （AST） in the control group and the left ventricular ejection fraction （LVEF） in the observation group， were all significantly increased compared with before treatment in the same group （P＜0.05）. Moreover， the improvement of the above indicators （except for TG and SBP） in the observation group was generally more significant than those in the control group （P＜0.05）. The left ventricular structure and functional parameters （LVM， LVEF， E/A ratio） of the two groups before and after treatment had varying degrees of correlation with the patients’ waist circumference， body weight， BMI， SBP， FBG and HbA1c. Moreover， BMI （observation group： β＝ 0.229， P＝0.004） and SBP （control group： β＝0.240， P＝0.004； observation group： β＝0.226， P＝0.007） were independent influential factors for LVM of the patients. CONCLUSIONS Liraglutide combined with conventional standard treatment can effectively control blood glucose in NAFLD patients with T2DM， reduce waist circumference， body weight and blood pressure， improve blood lipid disorders， and protect their cardiac structure and function.

Objective:To investigate the effect of separation exercise training of upper limb robot in improving upper limb motor function of stroke patients,and to explore the underlying mechanism by transcranial magnetic stimu-lation motor-evoked potential(MEP)evoked potentials. Method:Stroke patients were randomly divided into the experimental group(n=21)and the control group(n=23).The experimental group was trained with a fixed trajectories(the separation movement of elbow flexion-extension and shoulder adduction-abduction),while the control group underwent upper limb robot training with random movement trajectories(a compound action that can reach for objects).Both groups received robot train-ing once a day,20min/time,5 times/week for 3 weeks.The Fugl-Meyer assessment of upper extremity(FMA-UE)and modified Barthel index(modified Barthel index,MBI)were used to evaluate motor function.The la-tency period and central motor conduction time(CMCT)of MEP were detected before and after treatment. Result:After 3 weeks of treatment,the FMA-UE,MBI and MEP were improved compared with before treat-ment in the experimental group(P＜0.05),There was no significant difference between the FMA-UE,MBI and MEP of the control group and that before treatment(P＞0.05);There were no significant differences in in FMA-UE,MBI and MEP between-group comparisons after 3 weeks of treatment. Conclusion:The separation exercise training of the upper limb robot can improve the upper limb motor func-tion and enhance daily living activities in stroke patients,which may be related to enhanced remodeling of brain function in stroke patients.

Objective:To report five families of familial periodic paralysis.Methods:The clinical and genetic data of 5 families with familial periodic paralysis caused by SCN4A gene mutation who visited the First Affiliated Hospital of Henan University of Science and Technology from 2017 to 2022 were analyzed retrospectively.Results:The probands carried heterozygous missense mutations of SCN4A gene c. 3395G>A p. Arg1132Gln (Case 1), c. 2015G>A p. Arg672His (Case 2 and case 3), c. 2006G>A p. Arg669His (Case 4), c. 2111C>T p. Thr704Met (Case 5), respectively. Among them, four probands were diagnosed as hypokalemic periodic paralysis, one patient considered normal blood potassium periodic paralysis, and the treatment of acute attack was mainly potassium supplement. The main treatment for acute attacks was potassium supplementation, which was administered through intravenous infusion of potassium chloride combined with oral potassium chloride sustained-release tablets in the hospital. Simultaneously blood potassium levels and electrocardiogram monitoring were closely monitored. The main approach outside the hospital was to adopt a reasonable lifestyle and avoid triggering factors.Conclusions:The clinical manifestations caused by SCN4A gene mutation are diverse, and special attention should be paid in diagnosis, treatment and genetic counseling. Gene sequencing is an important molecular genetic diagnostic method.

OBJECTIVES: Patients with classical type 1 diabetes mellitus (T1DM) require lifelong dependence on exogenous insulin therapy due to pancreatic beta-cell destruction and absolute insulin deficiency. T1DM accounts for about 90% of children with diabetes in China, with a rapid increase in incidence and a younger-age trend. Epidemiological studies have shown that the overall glycated haemoglobin (HbA1c) and compliance rate are low in Chinese children with T1DM. Optimal glucose control is the key for diabetes treatment, and maintaining blood glucose within the target range can prevent or delay chronic vascular complications in patients with T1DM. Therefore, this study aims to investigate the glycemic control of children with T1DM from Hunan and Henan Province with flash glucose monitoring system (FGMS), and to explore factors associated with glycemic variability. METHODS: A total of 215 children with T1DM under 14 years old were enrolled continuously in 16 hospitals from August 2017 to August 2020. All subjects wore a FGMS device to collect glucose data. Correlation of HbA1c, duration of diabetes, or glucose scan rates with glycemic variability was analyzed. Glucose variability was compared according to the duration of diabetes, HbA1c, glucose scan rates and insulin schema. RESULTS: HbA1c and duration of diabetes were positively correlated with mean blood glucose, standard deviation of glucose, mean amplitude of glucose excursions (MAGE), and coefficient of variation (CV) of glucose (all P<0.01). The glucose scan rates during FGMS wearing was significantly positively correlated with time in range (TIR) (P=0.001) and negatively correlated with MAGE and mean duration of hypoglycemia (all P<0.01). Children with duration ≤1 year had lower time below range (TBR) and MAGE when compared with those with duration >1 year (all P<0.05). TIR and TBR in patients with HbA1c ≤7.5% were higher (TIR: 65% vs 45%, TBR: 5% vs 4%, P<0.05), MAGE was lower (7.0 mmol/L vs 9.4 mmol/L, P<0.001) than those in HbA1c >7.5% group. Compared to the multiple daily insulin injections group, TIR was higher (60% vs 52%, P=0.006), MAGE was lower (P=0.006) in the continuous subcutaneous insulin infusion group. HbA1c was lower in the high scan rates (≥14 times/d) group (7.4% vs 8.0%, P=0.046), TIR was significantly higher (58% vs 47%, P<0.001), and MAGE was lower (P<0.001) than those in the low scan rate (<14 times/d) group. CONCLUSIONS The overall glycemic control of T1DM patients under 14 years old in Hunan and Henan Province is under a high risk of hypoglycemia and great glycemic variability. Shorter duration of diabetes, targeted HbA1c, higher glucose scan rates, and CSII are associated with less glycemic variability.

Purpose: Laparoscopy is being increasingly accepted for pancreaticoduodenectomy. Stapled anastomosis (SA) is used extensively to facilitate laparoscopic pancreaticoduodenectomy (LPD); however, the incidence of anastomotic bleeding after stapled gastrointestinal anastomosis is still high. Methods: One hundred and thirty-nine patients who underwent LPD using Whipple method were enrolled in our study. We performed the SA with our reinforced method (n = 68, R method) and without the method (n = 71, NR method). We compared the clinical characteristics and anastomosis methods of patients with or without gastrointestinal-anastomotic hemorrhage (GAH), and operative parameters were also compared between the anastomotic methods. Results: Of the 139 patients undergoing LPD, 15 of them developed GAH. The clinical characteristics of patients with or without GAH were not significantly different except in the anastomotic method (P < 0.001). In the univariate logistic regression analyses, only the anastomotic method was associated with GAH. Furthermore, patients with the NR method had significantly higher incidences of GAH (P < 0.001) and Clavien-Dindo grade ≥ III complications (P < 0.001). Conclusion Our retrospective analysis showed that the SA performed with reinforced method might be a reform of SA without the reinforcement, as indicated by the lower incidence of GAH. However, further research is necessary to evaluate the utility of this reinforced method.

Objective:To compare the therapeutic results between axis pedicle screwing assisted by intraoperative 3-D navigation and freehand axis pedicle screwing in the treatment of Hangman fracture.Methods:A retrospective analysis was performed of the 64 patients with Hangman fracture who had received posterior axis pedicle screwing at Department of Spinal Surgery, The Sixth Hospital of Ningbo from May 2014 to December 2019. According to the placement methods of axis pedicle screws, they were divided into a navigation group ( n=34, subjected to axis pedicle screwing assisted by intraoperative 3-D navigation) and a freehand group ( n=30, subjected to freehand axis pedicle screwing). Pedicle screw placement time, operation time, intraoperative bleeding, fluoroscopy time, hospital stay, total hospitalization cost and complications were recorded and compared between the 2 groups. The accuracy of axis pedicle screw placement was evaluated according to the postoperative cervical CT and screw grading criteria proposed by Park et al. At admission, 3 months postoperation, and the last follow-up, neurological function of the patients was evaluated by modified Japanese Orthopedic Association (mJOA) score, neck pain was evaluated by visual analogue scale (VAS), and C2/3 vertebral body angulation and C2 forward displacement were measured. The clinical efficacy was evaluated by Moon grading at the last follow-up. Results:The navigation group and the freehand group were comparable due to insignificant differences between them in the preoperative general data ( P>0.05). The accuracy of screw placement in the navigation group (98.2%, 54/55) was significantly higher than that in the freehand group (85.2%, 46/54) ( P<0.05). The screw placement time, operation time, fluoroscopy time and total hospitalization cost in the navigation group were significantly more than those in the freehand group ( P<0.05). Vertebral artery injury occurred in 3 cases in the freehand group. Screw loosening, screw breakage or rod breakage occurred in none of the patients after operation. There was no significant difference between the 2 groups in the intraoperative bleeding, hospital stay or follow-up time ( P>0.05). In both groups, the VAS score, mJOA score, C2/3 vertebral body angulation and C2 forward displacement were significantly improved at 3 months postoperation and the last follow-up compared with those at admission ( P<0.05), but there was no significant difference between the 2 groups in the contemporary comparisons ( P>0.05). At the last follow-up, Moon grading in the navigation group was significantly better than that in the freehand group ( P<0.05). Conclusion:In the treatment of Hangman fracture, compared with freehand screw placement, axis pedicle screwing assisted by intraoperative 3-D navigation can improve accuracy and safety of screw placement and reduce postoperative complications, leading to better clinical efficacy.

This study reported a family of mitochondrial diabetes mellitus complicated with chronic hereditary pancreatitis. A 18-year-old woman presented with self-reported hyperglycemia and chronic epigastric pain was admitted to our hospital. Clinical data and family history were collected. Mitochondrial gene sequencing and whole exon gene sequencing showed that the proband carried mutation of mt.3243A>G and heterozygous mutation of SPINK1 c. 194+ 2T>C, which was considered as mitochondrial diabetes mellitus with chronic pancreatitis.

Objective: This study was carried out to analyze the clinical characteristics of pseudohypopara-thyroidism(PHP) type 1b, and to improve the understanding and diagnosis of the disease. Methods: Five patients with molecular diagnosis of pseudohypoparathyroidism type 1b in our hospital during 2018 were enrolled, their clinical data, biochemical indicators, imaging, and gene detection results were analyzed. Results: There were 4 females and 1 male, with low calcium, high phosphorus and high PTH serum concentrations. The onset age span was large and the onset symptoms were different. Family history may not be obvious. There was abnormal methylation of GNAS gene or deletion of exon STX16 in methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) detection while gene sequencing result was negative. Conclusion MS-MLPA detection was still needed in patients with suspected PHP but negative gene sequencing result. Different methylation abnormalities and copy number variations might be correlated with the onset symptoms and familial of type 1b PHP.
