Objective To investigate the effect of meridian exercises on blood glucose and clinical symptoms of community elderly type 2 diabetic patients.Methods Sixty elderly patients with type 2diabetes mellitus (T2DM) were selected from two communities from February to September in 2012.Thirty participants from one community received meridian excise-based group sport management (experiment group),the other 30 subjects from another community got meridian excise-based individual sport management (control group).Before and after the intervention,blood glucose and self-report symptoms were assessed.Results At baseline and after the intervention,there was statistically significant difference of postprandial blood glucose and self-symptom score between the two groups (t values were-5.954,-2.900,-4.214 and-3.798,respectively; all P＜0.05).After the intervention,experiment group showed statistically significant difference in self-assessment of symptom score from the control group (t=-5.484,P＜0.05).Conclusion Meridian exercises can efficiently improve diabetic patients' postprandial blood glucose and clinical symptons.

Blood C-peptide,first-void fasting urinary C-peptide/creatinine ratio ( UCPCR ),second-void fasting UCPCR,and 24 h urinary C-peptide (UCP) were determined in 90 type 2 diabetics and 30 health volunteers.The results showed that first-void fasting UCPCR and second-void fasting UCPCR were positively related to 24 h UCP and the index of islet β-cell function( all P＜0.01 ).

Objective To investigate the optimum ratio of medicine dosage for dexmedetomidine mixed with oxycodone used for patient-controlled intravenous analgesia (PCIA) after gastrointestinal surgery.Methods Eighty patients of both sexes, aged 35-64 yr, weighing 55-75 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective gastrointestinal surgery, were randomly divided into 4 groups (n=20 each) using a random number table: oxycodone group (group O), and different ratios of medicine dosage when dexmedetomidine was added to sufentanil groups (OD1-3 groups).At 15 min before the end of surgery, oxycodone 0.1 mg/kg was injected intravenously, and PCIA pump was connected simultaneously.In group O, the PCIA solution contained oxycodone 1.00 mg/kg in 100 ml of normal saline.In group OD1, the PCIA solution contained oxycodone 1.00 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.In group OD2 , the PCIA solution contained oxycodone 0.75 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.In group OD3, the PCIA solution contained oxycodone 0.50 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.The PCIA pump was set up to deliver a 0.5 ml bolus dose with a 15-min lockout interval and background infusion at 2 ml/h.Oxycodone 0.05 mg/kg was injected intravenously as a rescue analgesic, and visual analogue scale score was maintained ≤ 4.The requirement for rescue analgesics was recorded.The requirement for the rescue analgesic was recorded within 48 h after surgery.The number of successfully delivered doses, and occurrence of adverse reactions such as bradyeardia, hypotension, nausea, vomiting, over-sedation, somnolence, pruritus, and respiratory depression were recorded.Patient's satisfaction with analgesia was recorded at 72 h after surgery.Results No patients required the rescue analgesic or developed over-sedation, vomiting, respiratory depression and hypotension in the four groups.Compared with group O, the incidence of somnolence was significantly increased in group OD1, the incidence of nausea, somnolence, bradycardia and pruritus was decreased in OD2 and OD3 groups, and the degree of patient's satisfaction with analgesia was increased in OD1-3 groups (P＜0.05).Compared with group OD1, the incidence of nausea, somnolence, bradycardia and pruritus was significantly decreased in OD2 and OD3 groups, the degree of patient's satisfaction with analgesia was increased in group OD3 (P＜0.05) , and no significant was found in the degree of patient's satisfaction with analgesia in group OD2 (P＞0.05).Compared with group OD2, no significant was found in the incidence of adverse reactions (P＞0.05) , and the degree of patient's satisfaction with analgesia was significantly decreased in group OD3 (P＜0.05).The number of successfully delivered doses was significantly larger in group OD3 than in O, OD1 and OD2 groups (P＜0.05).Conclusion Dexmedetomidine 2.5 μg/kg added to oxycodone 0.75 mg/kg is the optimum ratio of medicine dosage when used for PCIA after gastrointestinal surgery.

Objective:To explore the influence of selective fetoscopic laser occlusion of chorioangiopagous vessels (FLOC) versus Solomon surgery in the management of twin-to-twin transfusion syndrome (TTTS) on procedure-related complications, fetal survival rate, and residual anastomoses.Methods:A total of 59 pregnant women with TTTS who underwent FLOC in the Third Affiliated Hospital of Zhengzhou University from May 2018 to March 2020 were retrospectively enrolled and divided into Solomon ( n=33) and selective FLOC groups ( n=26) based on the FLOC operation method. Placentae of 25 pregnant women (15 in the Solomon group, 10 in the selective FLOC group) with both survival twins were perfused to observe the type and diameter of the residual anastomoses. Fetal survival rate, procedure-related complications, and the type and diameter of residual anastomoses were analyzed and compared between the two groups using two independent samples t-test, Mann-Whitney U test, χ2 test and Fisher's exact test. Results:(1) The operating time of Solomon was shorter than that of selective FLOC [74 min (60-90 min) vs 95 min (81-123 min), Z=2.906, P=0.004]. But no statistically significant differences in the gestational week at operation, time of pregnancy end, and the interval between operation and pregnancy end was observed between the two groups (all P>0.05). (2) There was no statistically significant difference in the survival rate of both twins, one fetus, at least one fetus, and the incidence of postoperative twin anemia-polycythemia sequence (TAPS) and recurrent TTTS in the Solomon group and selective FLOC group [64%(21/33) vs 50%(13/26), χ2=1.107; 15%(5/33) vs 35%(9/26), χ2=3.044; 79%(26/33) vs 85%(22/26), χ2=0.326; 3%(1/33) vs 12%(3/26), χ2=1.368; 0% (0/33) vs 4%(1/26), χ2=1.118; all P>0.05]. (3) There was no statistically significant difference in the number of placentae with residual anastomoses or the number of artery-to-vein, vein-to-artery, artery-to-artery, and vein-to-vein anastomoses between the two groups (7/15 vs 6/10, 2/8 vs 4/15, 3/8 vs 4/15, 2/8 vs 5/15, 1/8 vs 2/15; Fisher's exact test, all P>0.05), but the diameter of the residual anastomoses in the Solomon group was smaller than that in the selective FLOC group [(0.8±0.3) and (2.2±0.7) mm, t=0.764, P=0.034]. (4) Among the four pregnant women developed TAPS after operation, one patient had two residual artery-to-vein anastomoses in the placenta with diameter of 0.54 mm and 0.43 mm, respectively; one patient had one artery-to-vein anastomosis with a diameter of 0.64 mm; one had one artery-to-artery and one vein-to-vein anastomosis with diameter of 1.56 mm and 1.89 mm, respectively. Conclusions:Compared with selective FLOC, Solomon surgery can reduce the vessel diameter of residual anastomoses in women with TTTS, but does not reduce postoperative complications, nor improve the pregnancy outcomes.

OBJECTIVETo investigate the distribution of rubidium (Rb), cesium (Cs), beryllium (Be), strontium (Sr), and barium (Ba) in blood and urine in general Chinese population.

METHODSA total of 18 120 subjects aged 6~60 years were enrolled from 24 regions in 8 provinces in Eastern, Central, and Western China from 2009 to 2010 based on the method of cluster random sampling. Questionnaire survey was conducted to collect the data on living environment and health status. Blood and urine samples were collected from these subjects, and the levels of Rb, Cs, Be, Sr, and Ba in these samples were determined by inductively coupled plasma mass spectrometry. The distribution of these elements in blood and urine in male or female subjects living in different regions was analyzed statistically.

RESULTSIn the general Chinese population, the concentration of Be in the whole blood was below the detection limit (0.06 μg/L); the geometric mean (GM) of Ba in the whole blood was below the detection limit (0.45 μg/L), with the 95th percentile (P95)of 1.37 μg/L; the GMs (95% CI)of Rb, Cs, and Sr in the whole blood were 2 374(2 357~2 392) μg/L, 2.01 (1.98~2.05) μg/L, and 23.5 (23.3~23.7) μg/L, respectively; in males and females, the GMs (95%CI)of blood Rb, Cs, and Sr were 2 506 (2 478~2 533) μg/L and 2 248 (2 227~2 270) μg/L, 1.88 (1.83~1.94) μg/L and 2.16 (2.11~2.20) μg/L, and 23.4 (23.1~23.7) μg/L and 23.6 (23.3~23.9) μg/L, respectively(P<0.01, P>0.05, and P>0.05). In the general Chinese population, the GM of urine Be was below the detection limit (0.06 μg/L), while the GMs (95%CI)of urine Rb, Cs, Sr, and Ba were 854 (836~873) μg/L, 3.65 (3.56~3.74) μg/L, 39.5 (38.4~40.6) μg/L, and 1.10 (1.07~1.12) μg/L, respectively; in males and females, the GMs (95%CI)of urine Rb, Cs, Sr, and Ba were 876 (849~904) μg/L and 832 (807~858) μg/L, 3.83 (3.70~3.96) μg/L and 3.47 (3.35~3.60) μg/L, 42.5 (40.9~44.2) μg/L and 36.6 (35.1~38.0) μg/L, and 1.15 (1.12~1.19) μg/L and 1.04 (1.01~1.07) μg/L, respectively (all P< 0.01). Correlation analyses showed that there were weak correlations between blood Rb and urine Rb (r=0.197)and between blood Sr and urine Sr (r=0.180), but a good correlation between blood Cs and urine Cs (r=0.487).

CONCLUSIONThe levels of Rb, Cs, Be, Sr, and Ba in the general Chinese population are similar to those reported in other countries, and there is a significant difference in the concentration of each element among the populations living in different regions, as well as significant differences in blood Rb, urine Rb, urine Cs, urine Sr, and urine Ba between males and females.

Objective: To analyze the rule and characteristics of school food poisoning incident in Guizhou Province during 2011-2018. Methods: Data of school food poisoning incidents were collected from the Foodborne Disease Outbreak Surveillance System in Guizhou Province during 2011-2018 and statistically analyzed. Results: A total of 78 cases of food poisoning occurred in schools in Guizhou Province during 2011-2018. Among the 1 506 cases, 869 hospitalized and 1 died. May was peak time for school food poisoning. Most of the incidents (83.33%, 65/78) occurred in the school canteens. Plant origin products (50%, 39/78), especially spoiled rice, were the most common types of food poisoning in school(16.67%, 13/78). Conclusion Primary and secondary school students were the largest group for school food poisoning in Guizhou province. It was necessary to strengthen the supervision and management of school canteens and surrounding places, as well as to improve the food safety awareness of food operators and students, preventing similar incidents from happening again.

Objective: To analyze the epidemiological characteristics of plant and mushroom poisoning events among people aged 0-19 in Guizhou Province from 2015 to 2019, so as to provide the basis for prevention and control of food poisoning events among children and adolescents. Methods: Data of people aged 0 to 19 involved in plant and mushroom poisoning incidents reported by the foodborne disease outbreak surveillance system in Guizhou Province from 2015 to 2019 were collected, verified, sorted and statistically analyzed. Results: From 2015 to 2019, there were 590 cases of plant and mushroom poisoning among people aged 0 to 19 in Guizhou Province, 1 441 people were poisoned and 5 died. In May and September, family and collective dining halls were the places with the highest incidence of plant and poisonous mushroom poisoning incidents, accounting for 90.68% (535/590) of the total incidents. Poisonous mushrooms and masanberry accounted for 71.69% (423/590) of the food poisoning causes, and 5 people died of poisoning were caused by poisonous mushrooms. Conclusion In the cases of plant and mushroom poisoning among people aged 0-19 years in Guizhou Province,preschool primary and middle school students in rural areas are most vulnerable population of poisoning, so it is necessary to strengthen the publicity and education on the prevention and control of toxic plant and mushroom poisoning among children and teenagers in rural areas, so as to reduce the occurrence of relevant poisoning incidents.

Objective: To analyze the occurrence and epidemiological characteristics of acute poisoning caused by Coriaria sinica maxdim in Guizhou Province during 2015 to 2020, and to provide scientific basis for prevention of Coriaria sinica maxim poisoning. Methods: A total of 176 cases of Coriaria sinica maxim poisoning were reported in Guizhou Province during 2015 to 2020, with all of the 505 affected were children and adolescents under 16 years old. No death was reported. Poisoning caused by Coriaria sinica maxim was most commonly reported in the year of 2020, with 97 reported incidents and 292 poisonings. Poisoning incidents were most freqently reported in the mature stage of Coriariasinica fruit during April to June, with 153 cases and 437 poisoning cases reported in May. The top three areas reporting Coriaria sinica maxim poisoning included Bijie, Anshun and Zunyi City, with the number of reported eventws being 57, 27, and 27, and poisoned children and adolescents of 160, 90, and 73. Most of the affected children were from rural areas. The median incubation period was 2 hours, and the primary clinical symptoms included vomiting( 93.66 %), nausea(58.02%) and abdominal pain(38.42%). Conclusion A large number of Coriaria sinica maxim poisoning incidents occur due to unsupervised access to Coriaria sinica maxim among rural children. The publicity and education of children, especially for rural left behind children, should be strengthened to reduce the incidence of Coriaria sinica maxim poisoning.

Objective To construct a Nomogram prediction model based on body position exer-cise training for patients with chronic constipation.Methods A total of 327 patients with chronic constipation from March 2021 to March 2023 were divided into qualified group(n=279)and unqual-ified group(n=48)according to their performance in body position exercises.General clinical mate-rials of the patients were collected,and univariate and multivariate Logistic regression analyses were performed to identify risk factors for unqualified body position exercises in patients with chronic con-stipation;the R software was used to construct a Nomogram model for predicting unqualified body po-sition exercises in patients with chronic constipation,and the receiver operating characteristic(ROC)curve and calibration curve were applied to verify the discrimination and consistency of the Nomogram model.Results There were no significant differences in gender,education level,history of smok-ing,history of alcohol abuse,history of hypertension,history of abdominal surgery,history of colonoscopy,and correct medication administration ratio between the two groups(P＞0.05);the un-qualified group had higher age,longer duration of chronic constipation,and a higher proportion of di-abetes history compared to the qualified group(P＜0.05);age,duration of chronic constipation,and diabetes history were independent risk factors for unqualified body position exercises in patients with chronic constipation(P＜0.05).The constructed Nomogram prediction model demonstrated excellent discrimination(area under the curve was0.923,95％CI,0.888 to 0.949,with sensitivity and specificity of 87.50％and 81.00％respectively)and consistency(H-L goodness-of-fit test x2=2.246,P=0.973).The clinical value of this Nomogram model in predicting unqualified body posi-tion exercises for patients with chronic constipation was high when the high-risk threshold probability ranged from 0.06 to 0.80.Conclusion Age,duration of chronic constipation,and diabetes history are independent risk factors for unqualified body position exercises in patients with chronic constipa-tion,and the Nomogram model constructed based on these multi-factor results has high discrimination and consistency in predicting unqualified body position exercises for patients with chronic constipation.
