Objective To investigate the effect of ultrasound-guided subcostal transverses ab-dominis plane block with dexmedetomidine mixed ropivacaine in related-living kidney transplantation donor.Methods Forty related living kidney transplantation donors (male 1 5 cases,female 25 cases, aged 20-60 years,ASA grade Ⅰ or Ⅱ)were randomized into dexmedetomidine group (group D,n =20)and control group (group C,n =20).All the patients received ultrasound-guided subcostal TAP block after operation,group D with dexmedetomidine 1 μg/kg and 0.375% ropivacaine to 20 ml,and group C with 0.375% ropivacaine 20 ml.All the patients were assessed with both Ramsay scores and Visual Analogue Scale (VAS)at rest or on moving at 2,4,8,24 and 48 hours after operation.The duration of sensory blockade,the first time and the times of pressing the analgesia pump in the first 24 hours after operation,the requirements of flurbiprofen axetil and midazolam were recorded.The u-rine on the first and the second day after operation and the first flatus time were compared.The plas-ma concentrations of urea nitrogen (BUN)and creatinine(Cr)before surgery and on the second and fifth day after operation were determined.Results Compared with group C,the scores of VAS were de-creased at 4 and 8 hours after operation in group D (P <0.05).There were no differences in Ramsay scores between the two groups.Compared with group C,less frequency of use of flurbiprofen axetil (15% vs 0%) and midazolam (10% vs 0%)in group D,longer time of sensory blockade,postponed time to firstly press the analgesia pump and the less frequency of pressing the analgesia pump in group D (P <0.05),the urine on the first day was increased and the first flatus time was earlier,the plasma concentrations of BUN and Cr were significantly lower on the second day after operation in group D (P < 0.05 ). Conclusion Dexmedetomidine mixed ropivacaine can promote the anaesthesia of ultrasound-guided subcostal TAP block with ropivacaine,prolong the time of sensory blockade and improve the recovery after nephrecto-my in living-related kidney donor.

Objective To observe the effect of kinesthetic imagery and visual imagery on upper limb rehabilitation among stroke survivors.Methods Forty-five hemiplegic stroke survivors were randomly assigned into a kinesthetic imagery training group (n=14),a visual imagery training group (n=15) or a control group (n=16).In addition to conventional rehabilitation,patients in the kinesthetic and visual imagery training groups were given 30 minutes of the appropriate imagery training once a day,five days per week for four weeks,while the control group relaxed or received health education for the same time.Before and after the 4-week intervention,the upper limb section of the Fugl-Meyer assessment (FMA-UE) and the modified Barthel index (MBI) were used to evaluate the motor function of the subjects' upper limb and their ability in the activities of daily living respectively.Results Before the intervention,there were no significant differences in the average FMA-UE and MBI scores among the 3 groups.After the intervention there was no significant difference between the average FMA-UE and MBI scores of the two training groups,but both were significantly better than the control group's averages.Conclusion Either kinesthetic or visual imagery training can improve the upper limb function of stroke survivors and their abihty in the activities of daily living.Their effectiveness is not significantly different.

OBJECTIVE: To investigate the diagnostic value of transcranial Doppler ultrasound in early stage cerebral arteriosclerosis. METHODS: We selected 50 patients with early cerebral arteriosclerosis as the disease group. At the same time we selected another 50 patients as a control group with no significant symptoms in the nervous system. By 2 MHz pulse Doppler probe through double-temporal windows and pillow windows Basilar artery (BA), the bilateral middle cerebral artery (MCA) was detected. In the TCD spectrum, we selected the spectrum of a single-family cardiac cycle, identified the starting point (ts), pulse-incisure point (ti), end point (te), and the peak velocity (tp), measured the time of the spectrum starting point to the peak velocity (Tp) and calculated the time required for the peak velocity in the share of ventricular systolic (Tp/Ti), the time required for the peak velocity in the share of the whole cardiac cycle (Tp/T). Tp, Tp/Ti and Tp/T were respectively named as time to peak velocity (TPV), peak-time index-1 (PTI-1) and peak-time index-2 (PTI-2). All data were analyzed by SPSS13.0. RESULTS: There was no significant difference in blood vessel velocity, PI, RI and S/D of BA and RMCA (P>0.05) between the control group and the disease group. Compared with the control group, TPV of the BA, LMCA and RMCA significantly extended, PTI-1 and PTI-2 of BA, LMCA and RMCA increased significantly in the disease group (P<0.01). In the disease group, there was no significant correlation between peak time index and PI, S/D (P>0.05). CONCLUSION TPV, PTI-1 and PTI-2 are sensitive indicators of early stage cerebral arteriosclerosis.

Objective:Understand the status of brushing teeth behavior of preschoolers in Shaanxi Province, to provide basis for oral health of preschoolers.Methods:By adopting the methods of multi-stage, stratified, geometric and cluster sampling, 1 370 kindergarten students at the age of 3-5 in Shaanxi Province were sampled as respondents to implement oral health questionnaire.Results:49.2%(674/1 370) children brushed their teeth every day, including only 14.8%(203/1 370) children brushing their teeth twice or above. Therefore, the difference of the brushing frequency (≥ 1 time/day) between urban and rural areas had obvious statistical significance ( χ2 value was 47.588, P<0.01). 98.7%(741/750) children used toothpaste, including only 6.9% (51/741) using toothpaste with fluoride. Therefore, the use of toothpaste between urban and rural areas has no statistical significance. Only 0.5% (4/751) children started to brush their teeth when their first deciduous tooth erupted. Therefore, the age for children starting to brush their teeth between urban and rural areas had obvious statistical significance ( χ2 value was 24.217, P<0.01). 65.2% (490/751)parents never helped their children to brush teeth, parents in rural areas even reached to 72.8% (227/312). Therefore, the brushing frequency for parents helping their children to brush teeth between urban and rural areas had statistical difference ( χ2 value was 16.192, P<0.01). Conclusions:The status of brushing teeth behavior of preschoolers in Shaanxi Province is lower than the national level, and the level in rural areas is obviously lower that in urban areas. The education and cultivation on brushing teeth behavior should be further strengthened in the future propaganda and education, especially, the power of propaganda on children and parents in rural areas should be strengthened.

Objective:To explore the incidence of non-thyroidal illness syndrome (NTIS) in children with type 1 diabetes mellitus (T1DM) and the correlation between triiodothyronine level and the severity of T1DM, thus providing evidence for clinical diagnosis and treatment.Methods:A total of 125 children initially diagnosed as T1DM at the Department of Endocrinology and Genetic Metabolism of Children′s Hospital of Shanghai Jiao Tong University from January 2015 to December 2019 were recruited.The data were retrospectively analyzed.The incidence of NTIS in T1DM children was explored.T1DM children were classified into euthyroid group and NTIS group, two independent sample t-test were used to compare the differences in multiple factors between euthyroid group and NTIS group in children with T1DM, and Spearman correlation analysis was used to further analyze the correlation between the levels of free triiodothyronine (FT3), total triiodothyronine (TT3) and the severity of children with primary T1DM. Results:The incidence of NTIS in 125 T1DM children was 26.4%(33/125 cases). FT3, TT3, total thyroxine (TT4), thyrotropin (TSH), pH value, HCO 3- and high density lipoprotein cholesterol (HDL-C) levels in NTIS group were significantly lower than those of euthyroid group [(3.10±0.45) pmol/L vs.(4.85±0.75) pmol/L, (0.60±0.28) nmol/L vs.(1.05±0.38) nmol/L, (65.77±23.41) nmol/L vs.(89.57±18.23) nmol/L, (0.91±0.89) mIU/L vs.(2.05±0.76) mIU/L, 7.21±0.17 vs.7.31±0.18, (11.49±7.54) mmol/L vs.(16.80±8.38) mmol/L, (1.08±0.49) mmol/L vs.(1.28±0.44) mmol/L]( t=4.56, 5.67, 4.48, 5.61, 2.82, 2.68, and 2.53, all P<0.05). Moreover, the anion gap (AG) level, blood glucose (BG) and triglyceride in NTIS group were significantly higher than those of euthyroid group [(22.53±8.33) mmol/L vs.(16.94±7.52) mmol/L, (24.85±4.71) mmol/L vs.(21.46±6.64) mmol/L, (2.72±2.05) mmol/L vs.(2.33±3.05) mmol/L]( t=3.22, 2.67 and 2.04, all P<0.05). The incidence of diabetic ketoacidosis (DKA) was statistically significant in euthyroid group, NTIS group and abnormal thyroid disease group (33.3% vs.63.6% vs.35.7%)( χ2=8.990, P<0.05). In T1DM children, FT3 was positively correlated with pH value and HCO 3-, and negatively correlated with AG level ( r=0.376 9, 0.439 7 and -0.411 9, all P<0.05). In addition, TT3 was positively correlated with pH value and HCO 3-, and negatively correlated with AG and BG ( r=0.513 2, 0.539 8, -0.482 4 and -0.211 5, all P<0.05). Conclusions:Children with T1DM are prone to have abnormal thyroid hormone levels, and the incidence of NTIS was 26.4%.The incidence of DKA differed in T1DM children with different thyroid functions.FT3 or TT3 level may contribute to evaluate the disease severity of T1DM children.

Objective:To investigate the effect and indications of pedicled myocutaneous flap and modified Masquelet technique in the repair of diabetic soft tissue and tibial bone defects.Methods:From January, 2017 to October, 2019, data of surgical treatment of 20 patients with diabetic soft tissue and tibial bone defects were retrospectively studied. The detects were repaired by the pedicled myocutaneous flap combined with modified Masquelet technique. There were 13 males and 7 females aged 40 to 65(average 51) years old. Preoperative ultrasound and CTA had confirmed that there was no occlusion in anterior and posterior tibial arteries. After debridement, the bone defect was 4-9 cm in length and the soft tissue defect was 3 cm×6 cm to 7 cm×10 cm. The initial antibiotic loaded bone cement filling of the bone and soft tissue defects was carried out. Then at 7-10 days later, had the bone cement placed earlier removed the remaining spaces of bone defect were again filled by antibiotic loaded bone cement. Meanwhile, the pedicled myocutaneous flap was transferred to repair the wound. The second stage of Masquelet technique was performed later, with an interval of 8-12(mean 9) weeks. The healing of wound and bone defect, and the complications were recorded. At 12 months after the surgery, the healing and appearance of the flap were evaluated by the standard proposed by Zhang Hao, and the functional recovery of the adjacent joint was evaluated by Johner-Wruhs standard. The treatment was considered successful when the symptoms were disappeared and no recurrence occurred.Results:All patients entered 13 to 28 months of follow-up, 20 months in average. The healing time for bone defect was 6-11 (average 9.0) months. All myocutaneous flaps survived with 18 flaps healed in the stage one and 2 delayed healing. Nine flaps appeared almost normal and 11 shown bloating. Seventeen flaps were found with partial sensation and 3 without sensation at all. The temperature of 7 flaps was found normal and 13 were slightly lower. Fourteen donor site scars were mild and 6 were obvious. The overall curative effect was satisfactory. Two patients had recurred infection. The rates of excellent and good functional recovery, infection control and success of treatment were at 90%(18/20) for each.Conclusion:Pedicled myocutaneous flap combined with modified Masquelet technique can repair diabetic soft tissue and tibial bone defects. It has a good therapeutic effect for short and medium terms.

Objective To investigate the clinical outcomes of patients with locally advanced uterine cervical cancer (UCC) treated by 3-dimensional high dose rate-intracavitary brachytherapy (3D HDR-ICBT) combined with complementary applicator-guided external beam radiotherapy (EBRT).Methods A total of 120 patients pathologically diagnosed with locally advanced UCC (tumors with a maximum diameter≥6 cm or ≥5 cm complicated with eccentric tumor growth) treated with concurrent chemoradiotherapy (CCRT) from June 2010 to June 2015 were recruited.Five fractions of 3D HDR-ICBT combined with complementary applicator-guided external beam radiotherapy were performed.The prescribed dose for HR-CTV and IR-CTV was 7 Gy (D9o) and 5-6 Gy (D90).The rectum,sigmoid colon,bladder and adjacent small intestine were delineated as the organs at risk.Intensity-modulated radiation therapy (IMRT) was used for EBRT (45 Gy/ 25f) combined with cisplatin-based chemotherapy every three weeks (75 mg/m2).Results The median follow-up time was 46 months (14-96 months).The 5-year local control rate (LCR),disease-free survival (DFS),and overall survival (OS) were 92.8％,76.6％ and 81.0％,respectively.The incidence rate of grade Ⅰ-Ⅱ genitourinary and gastrointestinal acute toxicities were 57.8％ and 14.6％,whereas 8.1％ and 2.9％ for grade Ⅲ toxicities.The incidence rate of later grade Ⅰ-Ⅱ genitourinary and gastrointestinal toxicities were 8.4％ and 5.3％,and 0.97％ and 1.3％ for grade Ⅲ late toxicities.Conclusions The combination of HDR-ICBT with an applicator-guided IMRT (ICBT+IMRT) yields low incidence of severe adverse events,relatively high LC and OS rate for locally advanced UCC.It is an efficacious comprehensive treatment of locally advanced bulky UCC.

Objective:To evaluate the effect of hierarchical diagnosis and treatment model of childhood bronchial asthma in Shanghai Pudong New Area.Methods:According to the principle of proximity, children aged 6 months-17 years who were diagnosed with bronchial asthma at Shanghai Children′s Medical Center from July 2016 to May 2017 were divided into two cohorts: the specialized hospital group and the community hospital group.Twelve months of treatment and follow-up were conducted.The asthma control level, Childhood Asthma Control Test (C-ACT) score, medication adherence and health economic indicators were collected.Results:A total of 524 children were included for data analysis and divided into the specialized hospital group (300 cases) and the community hospital group (224 cases). According to the Global Initiative for Asthma(GINA) criteria, there was no statistical difference in monthly asthma control level between the two groups (all P>0.05). In the 12 th month, the well-controlled rate of the specialized hospital group increased by 12.4% ( P<0.01), and that of the community hospital group increased by 22.9% ( P= 0.015). According to the C-ACT criteria, there was no statistical difference in the monthly well-controlled rate between the two groups (all P>0.05), and the rate maintained an upward trend.The rates of patients with good compliance in the specialized hospital group and the community hospital group at the 12 th month of hierarchical diagnosis and treatment were 78.3%(235/300 cases) and 75.0%(168/224 cases), respectively, and the difference was not statistically significant ( P=0.370). After 12 months of hierarchical diagnosis and treatment, the number of asthma attacks were 1.0 and 2.0 ( P=0.269), and the hospitalization rates for asthma were 3.0%(9/300 cases) and 4.9%(11/224 cases), respectively in the specialized hospital group and the community hospital group, and the diffe-rence was not statistically significant ( P=0.259); the number of respiratory infections in the specialized hospital group (2.0 times) was lower than that in the community hospital group (3.0 times), and the total cost of treatment in the community hospital group (2 471.5 Yuan) was lower than that in the specialized hospital group (3 445.5 Yuan), and the difference was statistically significant ( Z=-3.308, -3.336, all P<0.01). Twelve months after hierarchical diagnosis and treatment, the number of asthma attacks, the number of respiratory infections and the hospitalization rate for asthma in the two groups were all lower than those in the first 12 months of hierarchical diagnosis and treatment, and the difference was statistically significant (all P<0.01). Conclusions:Hierarchical diagnosis and treatment model of childhood asthma in Shanghai Pudong New Area can improve asthma control level, C-ACT score and asthma medication adherence, and enhance health economic benefits, thus it′s an effective way to manage childhood asthma.

Ferroptosis is a new form of regulated cell death discovered in recent years, which is iron-dependent cell death characterized by peroxidation of polyunsaturated fatty acid phospholipids. Recent studies have shown that radiotherapy can induce ferroptosis in cancer cells via ionizing radiation. Targeting ferroptosis plays a synergistic role in tumor suppression with radiation, which not only further deepens the connotation of radiobiology, but also provides a new perspective for tumor radiosensitization. This review systematically summarizes the occurrence and defense of ferroptosis, focusing on the key role of ferroptosis in the radiobiological effects of tumor cells and the potential application of ferroptosis in radiosensitization.
