Objective: To evaluate the effect of exercise prescription intervention among patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for guiding appropriate physical activity and glycemic control in this population. Methods: In July 2023, T2DM patients managed by two community health service centers in Qingjiangpu District, Huai'an City, Jiangsu Province, were selected as the study participants and randomly assigned divided into a control group and an intervention group. The control group received routine chronic disease management under the basic public health services, while the intervention group, in addition to receiving the same routine chronic disease management, was provided with exercise prescription to guide their physical activity at baseline (T0), after 3 months of intervention (T1), and after 6 months of intervention (T2). Data on weight-related indicators, glycated hemoglobin (HbA1c), and blood lipid were collected through physical examinations and laboratory tests at T0 and after 12 months of intervention (T3). The differences in indicators between the two groups before and after the intervention were analyzed using generalized estimating equations. Results: The intervention group consisted of 197 patients, including 99 males, accounting for 50.25%. The median disease duration was 7.10 (interquartile range, 7.80) years, and 113 patients had suboptimal HbA1c levels, accounting for 57.36%. The control group included 196 patients, including 99 females, accounting for 50.51%. The median disease duration was 6.10 (interquartile range, 7.00) years, and 100 patients had suboptimal HbA1c levels, accounting for 51.02%. Before the intervention, no statistically significant differences were observed between the two groups in gender, educational level, disease duration, pharmacological treatment, smoking, alcohol consumption, and HbA1c levels (all P>0.05). In the intervention group, the proportion of participants engaging in aerobic exercise and strength training increased from 78.17% and 8.12% at T0 to 85.79% and 16.24% at T3, respectively (both P<0.05). The results of the generalized estimating equations revealed significant interactions between group and time for waist-to-hip ratio, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) following the intervention (all P<0.05). A statistically significant difference in waist-to-hip ratio was found between the two groups (P<0.05), with a greater reduction observed in the intervention group compared to the control group. Significant differences in TC and LDL-C levels were noted across different intervention time points (both P<0.05). Specifically, the intervention group demonstrated reductions of 0.35 mmol/L in TC and 0.42 mmol/L in LDL-C from baseline to follow-up (both P<0.05). Conclusion The 12-month exercise prescription intervention can effectively enhance exercise participation and reduce waist-to-hip ratio, TC, and LDL-C levels among patients with T2DM.

BACKGROUND:Many studies have shown that total hip arthroplasty will improve low back pain in patients with hip-spine syndrome.However,there are few studies on the relationship between postoperative low back pain improvement and changes in spinal-pelvic sagittal parameters.This study aims to reveal their connections between the two. OBJECTIVE:To explore the relationship between the improvement of low back pain and changes in the spinal-pelvic sagittal parameters in patients with hip-spine syndrome after total hip arthroplasty. METHODS:A retrospective analysis was performed on the clinical and imaging data of 93 end-stage hip disease patients who underwent primary total hip arthroplasty and combined with low back pain and were admitted to Affiliated Hospital of Xuzhou Medical University from January 2019 to January 2022.Spinal-pelvic sagittal parameters were measured on lateral lumbar X-rays before surgery and 1 year at the last follow-up:pelvic incidence,pelvic tilt,sacral slope,lumbar lordosis,pelvic incidence-lumbar lordosis(difference between pelvic incident angle and lumbar lordosis angle).Visual analog scale score,Oswestry disability index,and hip Harris score were recorded before and 1 year after arthroplasty.The patients were divided into two groups according to whether the change in visual analog scale scores 1 year after surgery reached the minimal clinically important difference for low back pain treatment,including 45 cases in the low back pain unimproved group and 48 cases in the low back pain improved group.The preoperative general data of patients,differences in spinal-pelvic sagittal parameters,Oswestry Disability Index and hip Harris score before and after surgery were compared between the two groups. RESULTS AND CONCLUSION:(1)There was no significant difference in age,gender,surgical side,body mass index,and etiology between the two groups(P>0.05),and they were comparable.(2)There was no significant difference in visual analog scale scores before surgery(P>0.05).The visual analog scale scores of the low back pain improved group were lower than those of the low back pain unimproved group 1 year after surgery(P<0.01).(3)At 1 year after surgery,the lumbar lordosis of the low back pain unimproved group was significantly smaller than that before surgery,while the lumbar lordosis of the low back pain improved group was significantly smaller than that before surgery(P<0.01).At the same time,the pelvic incidence-lumbar lordosis mismatch in the low back pain unimproved group was greater than before surgery,while the pelvic incidence-lumbar lordosis mismatch in the low back pain improved group was smaller than before surgery,with significant differences between the two groups(P<0.01).There was no significant difference in the changes of other spinal-pelvic sagittal parameters between the two groups(P>0.05).(4)Preoperative lumbar Oswestry disability index and hip Harris score were not significantly different between the two groups(P>0.05).At 1 year after surgery,Oswestry disability index of the low back pain improved group was lower than that of the low back pain unimproved group and the hip Harris score was higher than that of the low back pain unimproved group(P<0.05).(5)The results showed that the improvement of low back pain was related to changes in spinal-pelvic sagittal parameters in patients with hip-spine syndrome after total hip arthroplasty,showing reduced lumbar lordosis and pelvic incidence-lumbar lordosis mismatch.Moreover,patients with improved low back pain after surgery had better functional scores,indicating that total hip arthroplasty improved spinal alignment and spinal-pelvic sagittal balance.For patients with hip-spine syndrome,a total hip arthroplasty performed before the onset of lumbar disease can have a favorable effect on the lumbar spine.

Objective To investigate the effects of limb ischemic post-conditioning (LIpostC) alone or its combination with therapeutic hypothermia (TH) on systemic inflammatory response and lung injury after cardiac arrest (CA) and resuscitation. Methods Twenty-one healthy male pigs weighing (37±2) kg were randomly divided into 3 groups (n = 7 each): control group, LIpostC group, and LIpostC+TH group. The animal model was established by 10 minutes of untreated CA and then 5 minutes of cardiopulmonary resuscitation (CPR).Coincident with the start of CPR, LIpostC was induced by four cycles of 5 minutes of limb ischemia followed by 5 minutes of reperfusion in the LIpostC and LIpostC+TH groups. After successful resuscitation, TH was implemented by surface cooling to reach a temperature of 32-34℃ until 4 hours post-resuscitation, followed by a re-warming rate of 1 ℃/h for 4 hours in the LIpostC+TH group. Normal temperature was maintained in the control and LIpostC groups. The resuscitation outcomes in each group were recorded during CPR. At 15 minutes prior to CA (baseline) and during 4 hours post-resuscitation, the level of arterial lactate was measured and PaO2/FiO2 was calculated, and extra-vascular lung water index (EVLWI) and pulmonary vascular permeability index (PVPI) were measured meanwhile by a PiCCO monitor. At 15 minutes prior to CA (baseline) and during 24 hours post-resuscitation, the levels of serum tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were measured by enzyme linked immunosorbent assay (ELISA). Results Six animals in each group were successfully resuscitated. Coronary perfusion pressure (CPP), duration of resuscitation, number of shocks and epinephrine dosage during CPR were not statistically significant among the three groups. The baseline of arterial lactate, PaO2/FiO2, EVLWI, PVPI and cytokines prior to CA were also not statistically significant among the three groups. The levels of serum TNF-α and IL-6 after resuscitation were gradually increased in all the three groups; however, the values of TNF-αand IL-6 were significantly lower in the LIpostC and LIpostC+TH groups than that in the control group, and they were further decreased in the LIpostC+TH group when compared to the LIpostC group [TNF-α (ng/L): 305±22 vs. 343±26 at 4 hours, 350±29 vs. 389±18 at 24 hours; IL-6 (ng/L): 239±14 vs. 263±19 at 24 hours, all P < 0.05]. The levels of lactate reached the peak at 2 hours post-resuscitation and then gradually decreased in all the three groups; it finally returned to the baseline in the LIpostC and LIpostC+TH groups, which was markedly lower than that in the control group (mmol/L: 1.4±0.7, 1.2±0.3 vs. 3.1±1.7, both P < 0.05). During 4 hours post-resuscitation, PaO2/FiO2 was significantly higher and EVLWI and PVPI were markedly lower in the LIpostC and LIpostC+TH groups than that in the control group; additionally, PaO2/FiO2 and EVLWI were further improved in the LIpostC+TH group than the LIpostC group [4-hour PaO2/FiO2 (mmHg, 1 mmHg = 0.133 kPa): 391±26 vs. 361±20; 4-hour EVLWI (mL/kg): 10.1±1.5 vs. 12.1±1.2, both P < 0.05]. Conclusion LIpostC can be used to alleviate systemic inflammatory response and lung injury after porcine CA and CPR, and its combination with TH further enhanced its protective effects.

Objective To evaluate the effectiveness of regional electrocardiographic consultation network for primary medical institutions.Methods A distance electrocardiographic ( ECG ) consultation center was established in Yuyao People′s Hospital in September 2012, which was connected to 56 regional primary medical through internet.The online consultation was provided by ECG specialists in the center for general practitioners in regional primary health care institutions.Additionally, the ECG training course was also conducted monthly for general practitioners.The 2-year data of ECG consultation were retrospectively reviewed and the effectiveness of the consultation network was evaluated.Results During the past two years, 86 593 electrocardiograms were uploaded by primary medical institutions, in which 3 976 were required for consultation. The monthly number of electrocardiograms sent by general practitioners was increased from 3 269 ±290 in the first year to 3 947 ±376 in the second year ( P<0.01 ) .However, the requirements of ECG consultation were not significantly different between two years.Compared to the first year, the rates of consultation requirements, misdiagnosis and missed diagnosis for ECGs of atrial and ventricular premature beats, atrial fibrillation, supraventricular tachycardia, left and right bundle branch blocks,ⅠandⅡdegree atrioventricular blocks and myocardial infarction were significantly decreased ( all P<0.05) in the second year;meanwhile there was a tendency towards the reduction for ECGs of atrial flutter and Ⅲ degree atrioventricular block in the second year.Conclusion The regional electrocardiographic consultation network is effective to improve the capability of primary medical institutions in electrocardiographic diagnosis.

A total of 105 patients with first-episode schizophrenia (male =51,female =54) and 99 normal controls (male =51,female =48) were included into this retrospective case-control study.Childhood trauma questionnaire-28 item short form (CTQ-SF) was used to assess the experience of childhood abuse.The result of binary logistic regression showed that emotional abuse (β =0.630,P ＜ 0.05) and emotional neglect(β =0.270,P ＜ 0.05) were included into the final model of predicting schizophrenia.It indicates that patients with first-episode schizophrenia experienced more early life stress than controls.Particularly emotional abuse and emotional neglect may play important roles in the onset of schizophrenia.

Objective To analyze the timing and frequency of spontaneous gasping during cardiopulmonary resuscitation in a rat model,and evaluate its value bearing some relation to duration of cardiac arrest (CA ) in predicting the severity of post-resuscitation myocardial dysfunction.Methods Twenty-seven healthy Sprague-Dawley rats were randomly (random number)divided into 3 groups according to different durations of CA:CA 4 min (n=9),CA 6 min (n=9)and CA 8 min (n=9).CA of rats was electrically induced and untreated for 4,6 or 8 min respectively in the corresponding groups,and then cardiopulmonary resuscitation (CPR)was initiated and continued for 8 min in all animals.The emergence timing and frequency of spontaneous gasping during cardiopulmonary resuscitation and resuscitation outcomes were documented.Myocardial function such as cardiac output,ejection fraction and Tei index was measured by echocardiography prior to CA and at 1 h,2 h and 4 h post-resuscitation.Results The earliest appearance of gasping with highest frequency was observed in the CA 4 min group during CPR.Gasping appeared later with decreased frequency observed following longer duration of CA.There were statistically significant differences in the timing and frequency of gasping among the 3 groups.In the CA 4 min group with frequent gasping,all animals were successfully resuscitated with 8-min CPR with the least number of defibrillation,which was significantly better than that in the CA 8 min group.During the evaluation of post-resuscitation myocardial function,cardiac output,ejection fraction and myocardial work index (Tei index) were better in the CA 4 min group with frequent gasping,worse in the CA 6 min group and worst in the CA 8 min group, showing statistically significant differences in cardiac function among the 3 groups. Conclusions The spontaneous gasping appeared sooner with higher frequency during cardiopulmonary resuscitation indicated shorter duration of CA,and predicted better success of resuscitation and post-resuscitation myocardial function.

Objective　To evaluate the technique and clinical outcomes of modified transperitoneal laparoscopic radical prostatectomy.　Methods　A total of 285 patients received the operation with mean age of 67 years (50-76 years) from January 2008 to April 2012.Mean level of PSA was 15.7 μg/L (1.8 -50.0 μg/L),and mean prostatic volume was 44 ml (26 -74 ml). No lymph node or seminal vesicle involvement was found by CT or MR and radionuclide bone scan revealed no metastasis.271 cases were confirmed diagnosis by prostatic biopsy and 14 were detected through pathological studies of TURP specimens.Gleason score ranged from 6 to 8.14 cases were in clinical stage T1b,29 cases in T1c,214 cases in T2 and 28 cases in T3a.Transperitoneal approach and modified technique involving bladder neck dissection,nervesparing technique and vesicoureteral anastomosis were applied on patients.　Results　Mean operative time was 105 min (55 -150 min).Mean intraoperative estimated blood loss was 240 ml (50-800 ml).Rectal injures occurred in 2 cases and were repaired under laparoscopy.Drainage tube and urinary catheter were removed 48 -72 h and 5 -8 d postoperatively.Postoperative hospital stay was 7 d (5 - 11 d).Positive surgical margin was present in 58 patients.Mean follow-up time was 29 months (3 -50 months).Complete continence were found in 208 patients immediately after catheter removal.68 patient recovered continence within 3 months and 9 patients remained incontinence 3 months after surgery. Normal erection presented in 42 of the 57 cases with nerve-sparing.　Conclusions　Transperitoneal laparoscopic radical prostatectomy is safe and efficient.Higher efficiency and lower complication rate have been achieved through modified laparoscopic technique involving bladder neck dissection,nerve-sparing technique and vesicoureteral anastomosis.

Objective To study the effect of tranilast on cyclosporine A (CsA)-induced epithelial-to-mesenchymal transition in human renal tubular epithelial cells, and investigate the mechanism of its antifibrotic effect. Methods Cultured HK-2 cells were divided into four groups: (1)In the control group, cells were treated without any medicine; (2) The cell were treated with CsA (4. 2μmol/L) for 72 h; (3) The cells were treated with a combination of CsA (4. 2 μmol/L) and tranilast (100μmol/L); (4) The cells were treated with tranilast (100 μmol/L) alone for 72 h.Morphological changes of the cells were assessed by phase-contrast microscopy. The immunofluorescence and Western blotting were adopted to detect the expression of E-cadherin, α-SMA and OPN mRNA and proteins respectively. Results Tranilast could markedly ameliorate the morphological changes of HK-2 cells stimulated by CsA. The irmmunofluorescence staining revealed the expression of E-cadherin was markedly decreased in HK-2 cells stimulated with CsA for 72 as compared with the control group, while the expression of α-SMA and OPN was significantly higher in CsA group than the control group. The expression of E-cadherin in the CsA + Tranilast group was higher than the CsA group, while the expression of α-SMA and OPN in the CsA + Tranilast group was lower than the CsA group. Western blotting showed that protein expression level of E-cadherin in CsA group was dramatically lower than that in the control group (P＜0. 05), while that of α-SMA and OPN in CsA group was significantly higher than in the control group (P＜0.05). The protein expression level of E-cadherin in HK-2 cells in the CsA + Tranilast group was markedly higher than in the CsA group (P＜0.05), and that of α-SMA and OPN in CsA + Tranilast group was significantly lower than in the CsA group (P＜0. 05). Conclusion Tranilast can block the CsA-induced epithelialto-mesenchymal transition in HK-2 cells probably by suppressing the expression of OPN.
