Objective To observe neurobehavior and pathological changes of spinal cord injury (SCI) model in adult rats.Methods The Basso Beattie Bresnahan (BBB) scoring,histological and immunohistochemical changes after SCI were observed by means of self-designed spinal cord injurying device controlled by electrocircuit.Results From the 3rd day(1.0 ± 0.7),the BBB score of injured group began to increase (increased to 4.2 ± 1.3significantly at 7th day,and at the 28th day was 7.2 ± 1.3),and the hind limb could not support the body weight.Degeneration,necrosis of lots of neurons and glial cells proliferation could be observed obviously in spinal cord injured group.Immunohistochemical experiments showed that the grey level began to decrease 2nd hour after injury,went down the minimum at the 1st day,then 3rd day recovered,and at 28 th day was still lower than that of sham group.The glial fibrillary acidic protein (GFAP) immunostaining positive cells area was gradually increased from 3rd day,reached the apex in the 14 th day,then decreased in the 28 th day.The changes of neuron specific enolase (NSE),neurofilament protein 200 (NF200) and GFAP had a close relationship with BBB score (r =0.856,0.856,0.795 respectively,P＜0.01).Conclusion The changes of NSE,NF200,GFAP after spinal cord injury reflect the characteristic of pathological change,which have a close relationship with functional recovery.

Objective To investigate the accuracy of real-time continuous glucose monitoring(RT-CGM)system in the type 2 diabetes mellitus(T2DM). Methods A total of 318 subjects hospitalized between 2013 May to 2014 August were recruited. Each subject received a RT-CGM system. In order to calibrate the interstitial glucose level, finger-stick blood glucose were measured at least four times every day. Patients were divided into three groups according to their finger-stick blood glucose level:≤6.99 mmol/L, 7.0-10.0 mmol/L and≥10.01 mmol/L. Pearson correlation was used to analyze the relationship between the finger-stick glucose and interstitial glucose gained from RT-CGM. Clarke error grid analysis was used to analyze the accuracy of RT-CGM. Results (1)A total of 2, 815 glucose meter values from finger-stick were com?paired with glucose from RT-CGM. A positive relationship(r=0.847)were found between CGM and finger-stick blood glu?cose. The correlation was closer with higher finger-stick blood glucose levels(r=0.457, 0.648 and 0.852 respectively in≤6.99 mmol/L group, 7.0-10.0 mmol/L group and≥10.01 mmol/L group. P<0.001).(2)The Clarke error grid analysis re?vealed that 76.69%of the readings from RT-CGM were clinical perfect (zone A), 20.28%were acceptable (zone B), 3.03%were unacceptable (zone C-E). Clinical perfect rate was lower when the finger-stick glucose≤6.99 mmol/L , compared with that when it is between 7.0-10.0 or≥10.01 mmol/L group(73.12%vs 78.63%&79.28%,P<0.05), there was no significant difference between group of 7.0-10.0 mmol/L with group≥10.01 mmol/L (P>0.05). Conclusion RT-CGM provides accu?rate blood glucose values to guide the treatment of diabetes, and the accuracy is more reliable in high glucose environment.

Objective To study the target setup margin and dose evaluation for cervical cancer patients with volume-modulated arc therapy in the off-line adaptive radiation therapy (off-line ART),Methods A total of fifty patients with cervical cancer were randomly divided into test group and control group.Cone beam CT scanning was performed twice a week,the setup errors in directions of LR,AP and CC were recorded in the whole treatment process.The target setup formula was used to calculate the new CTV-PTV setup margin.At the same time,the setup error was returned to planning isocenter (ISO).For the control group,the dose was recalculated on the basis of the original PTV after considering ISO shift.For the test group,the dose was also recalculated after the new extended boundary of the target.The dosimetric parameters of CTV and organs at risk (OAR) were evaluated between two groups after dose recalculation.Results According to the target setup formula,extended boundaries of CTV in the direction of LR,AP,CC were 0.45,0.46 and 0.82 cm,respectively.The test group increased in CTV with D100％ and D95％ (t =-8.16,-6.73,P ＜0.05) and decreased in femoral head with V40,V30 and D (t=3.14,-9.52,-7.48,P＜0.05) than the control group.The test group decreased in the pelvis with V34 and D than control group (t =10.14,-9.38,P ＜0.05).Conclusions The CTV-PTV setup margin and the dose of OAR were effectively reduced,and the coverage of target area was extended when the off-line ART technology was conducted in the volume-modulated arc therapy for cervical cancer.

Objective To evaluate the applicability of a modified U-shaped forearm flap for the repair of small-and medium-sized defects in the oral and maxillary areas to provide a reference for clinicians.Methods This study was re-viewed and approved by the Ethics Committee,and informed consent was obtained from the patients.Ten patients with small-and medium-sized defects in the oral and maxillary areas underwent surgical repair using modified U-shaped fore-arm flaps.There were 8 males and 2 females aged 43-72 years.The donor site was apposed primarily after harvesting the modified U-shaped forearm skin flap.The flaps ranged from 6 cm × 4 cm to 8 cm × 5 cm in size.Six months after the operation,hand movements(finger extension,fist clenching,wrist rotation upward and wrist rotation downward),the forearm donor site,hand sensations and the satisfaction score for the postoperative quality of the scar at the donor site were evaluated(0 to 10;0:very unattractive,10:very satisfactory).Results A total of 10 patients with modified U-shaped forearm flaps survived.One patient developed venous crisis 24 hours after surgery and survived after surgical ex-ploration.Delayed healing occurred at the donor site of the forearm in 1 patient,and the wounds at the donor site of the forearm in the other patients all healed in the first stage.One patient presented with dysesthesia in the hand 2 weeks af-ter surgery and recovered within 3 months.Six months after surgery,all patients had no limited hand movement and no paresthesia at the forearm donor site or hand.The patients were basically satisfied with the appearance of the donor site,and the average satisfaction score of the subjective questionnaire was 8.4 points.Conclusion Modified U-shaped fore-arm flaps can directly close forearm donor site wounds,which avoids surgical trauma to the secondary donor site and sig-nificantly reduces related complications.Modified U-shaped forearm flaps provide an alternative to conventional forearm flaps for the repair of small-and medium-sized defects in the oral and maxillary areas.

Objective To investigate the effect of green laser anatomical vaporization on patients with benign prostatic hyperplasia(BPH)and type 2 diabetes mellitus(T2DM),as well as its impact on inflammatory factors,quality of life,and urethral stricture.Methods A total of 120 patients with BPH and T2DM who were treated at the First Affiliated Hospital of Xinxiang Medical University from March 2021 to August 2022 were selected as the research subjects.The patients were divided into a control group and an observation group according to the surgical approach,with 60 cases in each group.Patients in the control group underwent green laser selective photovaporization,while patients in the observation group were treated with green laser anatomical vaporization.The intraoperative and postoperative recovery indicators such as operation time,intraoperative blood loss,prostate resection quality,catheter indwelling time,bladder irrigation time,and hospitalization time of patients between the two groups were compared.The serum levels of interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)were detected by using enzyme-linked immunosorbent assay,and the serum levels of malondialdehyde(MDA)and lipid peroxide(LPO)were detected by using immunofluorescence assay before surgery,3 days after surgery,and 7 days after surgery.The international prostate symptom score(IPSS)was used to assess prostate symptoms,the urinary symptom distress score(USDS)was used to assess urinary symptoms,the dynamic urodynamic monitor was used to measure urodynamics[maximum flow rate(Qmax),residual urine volume(RUV)],the enzyme-linked immunosorbent assay was used to detect the serum level of total prostate specific antigen(tPSA),the international index of erectile function-5(IIEF-5)was used to assess erectile function,and the BPH quality of life(BPH-QOL)scale was used to assess quality of life before surgery,3 months after surgery,and 6 months after surgery.The incidence of complications such as urethral stricture,urinary tract irritation,bladder neck contracture,urinary retention,and secondary bleeding was compared between the two groups.Results The operation time of patients in the observation group was significantly longer than that in the control group,the intraoperative blood loss was significantly less than that in the control group,and the bladder irrigation time,catheter indwelling time,and hospitalization time were significantly shorter than those in the control group(P＜0.05).There was no statistically significant difference in the quality of prostatectomy between the two groups of patients(P＞0.05).Before surgery,there was no statistically significant difference in the levels of serum TNF-α,IL-6,MDA,and LPO between the two groups of patients(P＞0.05).On postoperative days 3 and 7,the levels of serum TNF-α,IL-6,MDA,and LPO in both groups were significantly higher than those before surgery,and the levels of serum TNF-α,IL-6,MDA,and LPO in the observation group were significantly lower than those in the control group(P＜0.05).Before surgery,there was no statistically significant difference in the IPSS and USDS scores between the two groups of patients(P＞0.05).At 3 and 6 months after surgery,the IPSS and USDS scores of patients in both groups were significantly lower than those before surgery,and the IPSS and USDS scores of patients in the observation group were significantly lower than those in the control group(P＜0.05).Before surgery,there was no statistically significant difference in RUV,Qmax,and serum tPSA levels between the two groups of patients(P＞0.05).At 3 and 6 months after surgery,the RUV and serum tPSA levels of patients in both groups were significantly lower than those before surgery,while the Qmax was signifi-cantly higher than that before surgery(P＜0.05).The RUV and serum tPSA levels of patients in the observation group were significantly lower than those in the control group,while the Qmax was significantly higher than that in the control group(P＜0.05).Before surgery,there was no statistically significant difference in the IIEF-5 and BPH-QOL scores of patients between the two groups(P＞0.05).At 3 and 6 months after surgery,the IIEF-5 scores of patients in both groups were significantly lower than those before surgery,while the BPH-QOL scores were significantly higher than those before surgery(P＜0.05).The IIEF-5 and BPH-QOL scores of patients in the observation group were significantly higher than those in the control group(P＜0.05).The total incidence of complications in the control group and the observation group was 16.67％(10/60)and 5.00％(3/60),respectively,and the total incidence of complications in the observation group was significantly lower than that in the control group(x2=4.227,P＜0.05).Conclusion Green laser anatomical vaporization in the treatment of BPH patients with T2DM can optimize the surgical process,reduce inflammatory stress and the risk of complications,promote early postoperative recovery,improve urodynamics and sexual function,relieve symptoms,and enhance quality of life.

Objective: To evaluate the vitamin D nutritional status in Chinese women of child-bearing age by analyzing serum 25-hydroxyvitamin D level in 2010-2012. Methods: Data were obtained from the China Nutrition and Health Survey in 2010-2012. Using cluster sampling and proportional stratified random sampling, 1 514 women of child-bearing age (18-44 years old) from 34 metropolis and 41 small and medium-sized cities were included in this study. Demographic information was collected by questionnaire and serum 25-hydroxyvitamin D concentration was determined by radioimmunoassay, in accordance with the 2010 Institute of Medicine of the National Academies standards. We compared differences in vitamin D levels, specifically serious deficiency, lack of deficiency, insufficiency, and excess. Results: The overall serum 25-hydroxyvitamin D level of Chinese urban women of child-bearing age (P₅₀ (P₂₅-P₇₅)) was 20.1 (15.1-26.3) ng/ml; minorities had a significantly higher serum 25-hydroxyvitamin D level of 22.0 (15.9-27.5) ng/ml compared with women of Han nationality (19.8 (14.9-26.2) ng/ml) (χ²=7.02, P=0.008). The proportions of women with serious deficiency, lack of deficiency, insufficiency, and excess vitamin D were 11.6% (n=175), 37.9% (n=574), 35.1% (n=531), and 0.3% (n=5), respectively. Only 15.1% (n=229) of women of child-bearing age had normal vitamin D nutritional status. No significant differences in vitamin D nutritional status were observed according to age, body mass index, city, nationality, educational level, marital status, or household income per capita (P>0.05). Conclusion Most Chinese urban women of child-bearing age have poor vitamin D levels and require vitamin D supplementation.
