Objective To investigate the different effects of clozapine and risperidone on levels of blood glucose in patients with schizophrenia. Method 200 qualified cases selected from psychiatric department were divided into two groups randomly, of which 100 cases accepted the treatment with clozapine and the other 100 cases with risperidone. Blood glucose tests were used before treatment ,4 weeks after treatment and 8 weeks after treatment Results There was significantly higher blood glucose level in clozapine－ treated group than in risperidone－ treated group after 4 or 8 weeks treatment. The number of cases who had elevated blood glucose level (>6.1 mmol/L) in clozapine－ treated group was significantly more than in risperidone－ treated group. Conclusion The glucoregulatory abnormality which leads to glucose elevation in clozapine－ treated patients is greater than in risperidone－ treated patients. Additional motivation to clinical monitor for antipsychotic treatment－ related hyperglycemia is indicated.

Objective To study the pathogenesis, clinical symptoms, surgical treatment and preventive measures of esophagogastric-arterial fistula following resection for carcinoma of the esophagus and cardia. Methods The clinical data of 18 patients with esophagogastric-arterial fistula were retrospective analyzed. Results There were 14 patients of esophageal carcinoma and 4 patients of cardiac carcinoma.7 patients had supra-aortic esophagogastric anastomosis(2 near the apex of pleura) and 11 had anastomosis under the aortic arch. Fatal hemorrhage occurred postoperatively from 11 to 93 days. The interval between hemorrhage and death varied from being instant to 18 days.All patients died. Conclusion The surgical treatment provide an opportunity for those patients. Successful management is possible if early diagnosis is made and prompt surgical management is undertaken. Preventive measures of peptic ulcer and esophageal fistula can decrease occurrence of this complication.

Objective:To investigate the treatment failure sites, risk factors, and survival rates of patients with persistent or recur-rent squamous cell carcinoma (SCC) of the cervix within one year after concurrent chemoradiotherapy (CCRT). Methods:Clinical data of 30 patients with persistent or recurrent SCC of the cervix within one year after CCRT between June 2006 and June 2011 were ana-lyzed retrospectively. These data were compared with those of another 35 SCC cases without recurrence after complete remission. These 35 patients were treated homeochronously (from 2006 to 2011) and randomized in the control group. Results:Among the 30 pa-tients, 25 exhibited distant metastases;14 of these 25 patients were observed within six months after CCRT. Univariate analysis showed a higher incidence of pelvic or para-aortic lymphadenectasis and SCC-ag>10 ng/mL in the group with persistent or recurrent disease be-fore treatment (P<0.01). Multivariate analysis by logistic regression revealed that the pre-therapeutic pelvic or para-aortic lymph node enlargement and SCC-ag>10 ng/mL were found as the independent risk factors. Palliative chemotherapy ranked as the first method used to treat patients. The two-year survival rate was 21.7%, and the median survival time was 17 months. Conclusion:Patients with persistent or recurrent SCC of the cervix after CCRT possibly exhibited a high rate of distant metastasis with poor prognosis. The pre-therapeutic pelvic or para-aortic lymph node enlargement and SCC-ag>10 ng/mL were found as the independent risk factors of per-sistent or recurrent SCC within one year after CCRT.

ObjectiveTo explore the therapeutic effect and mechanism of dexamethasone combined with puerarin for treatment of paraquat (PQ) poisoned rats.Methods Thirty Sprague Dawley (SD) rats were divided by random number table into 5 groups: control, model, dexamethasone, puerarin and combined groups, 6 rats in each group. The PQ poisoned rat model was established by intraperitoneal injection of PQ 25 mg/kg (1 mL), while in the rat of the control group, the same volume of normal saline was injected intraperitoneally. After 2 hours, in the rat of dexamethasone group, 20 mg/kg dexamethasone in 1.5 mL was injected intraperitoneally, and in the rat of puerarin group, 100 mg/kg puerarin in 1.5 mL was injected intraperitoneally. In the rat of combined group, 20 mg/kg dexamethasone combined with 100 mg/kg puerarin in a total amount of 1.5 mL was injected intraperitoneally. In the control group and model group, 1.5 mL of normal saline was injected intraperitoneally. The above mentioned treatments were repeated once more 26 hours later. In 26-50 hours after modeling, urine was collected, and urine N-acetyl-beta-D-amino glycosidase enzymes (NAG) was tested; at the 50th, abdominal aortic blood was collected to test oxygen partial pressure (PaO2). The lung index, kidney index, and the levels of malonaldehyde (MDA), superoxide dismutase (SOD) and myeloperoxidase (MPO) were measured in the left lung and kidney tissue homogenates separately; the right lung and kidney were
harvested to observe pathological changes under light microscope. Another 30 SD rats were treated the same as above measures but no sacrifice to observe 30-day survival rate in each group.Results The lung index, kidney index, NAG in urine, MDA and MPO levels in lung and kidney tissue homogenates in model group were significantly higher than those in the control group [lung index: 9.80±1.83 vs. 4.97±1.14, kidney index: 9.40±1.32 vs. 7.01±0.32, NAG (U·kg-1·day-1): 1.93±0.18 vs. 0.41±0.03, MDA of lung (nmol/mg): 1.04±0.15 vs. 0.28±0.10, MDA of kidney (nmol/mg): 1.39±0.16 vs. 0.66±0.13, MPO of lung (U/g): 1.14±0.08 vs. 0.81±0.06, MPO of kidney (U/g): 0.88±0.08 vs. 0.52±0.12]; while PaO2 [mmHg (1 mmHg = 0.133 kPa): 59.83±4.40 vs. 97.00±2.83] and SOD (U/mg): lung was 27.38±3.48 vs. 86.88±5.88; kidney was 24.18±3.74 vs. 57.86±6.14) were obviously lower than those in control group (allP < 0.05). After drug treatment was given, lung index (7.21±1.87), urine NAG (1.01±0.21) and MDA (lung was 0.49±0.09, kidney was 0.85±0.08), MPO (lung was 0.97±0.07, kidney was 0.68±0.10) in the puerarin group were significantly lower than those in model group, while PaO2 (82.17±5.38), SOD (lung was 68.99±6.51, kidney was 37.90±3.62) were remarkably higher than those in model group (allP < 0.05). The improvement in the indexes related to the kidney injury was not obvious in dexamethasone group and in the dexamethasone combined with puerarin group, while the lung and kidney pathological changes were lesser in extent in each of the above two treatment groups than those in model group. The 30-day survival rate in model group was significantly lower than that in control group (0% vs. 100.0%);the 30-day survival rates in control group, dexamethasone group, puerarin group and combined group were remarkably higher than those in model group (100.0%, 16.7%, 50.0% and 33.3% vs. 0%, allP < 0.05). But there were no statistical significant differences in the survival rates among those treatment groups (P > 0.05).Conclusions Dexamethasone can improve the prognosis of rats with acute paraquat intoxication, it can provide lung protection markedly, but cannot provide significant protective effect on kidney; puerarin has therapeutic effect on rats with acute PQ poisoning, it can provide not only lung protection but also kidney protection. The effect of treatment with dexamethasone combined with puerarin is not superior to that by using dexamethasone or puerarin alone.

Paeoniflorin and its derivatives are main active compounds inGui-Zhi Fu-Ling Capsule (GZFLC). In this study, molecular imprinted polymer (MIP) was prepared by sol-gel process to obtain paeoniflorin and its derivatives in GZFLC. The static adsorption capacity of MIP was measured by scatchard equation. The results showed that the maximum apparent absorbing capacity of MIP was 52.28 mg·g-1. One-step separation of paeoniflorin from 4 g methanol samples of GZFLC was 197 mg with the purity of 89.3%. It was concluded that paeoniflorin MIP can be used to separate phaoniforin and its analogues from GZFLC.

OBJECTIVETo evaluate the efficacy of atorvastatin in preventing contrast agent-induced nephropathy (CIN) in patients undergoing coronary angiography and explore the mechanism.

METHODSA total of 180 patients undergoing coronary angiography or percutaneous coronary interventions (PCI) were randomized into regular dose and high dose atorvastatin groups (n=90). Serum creatinine (Scr), glomerular filtration rate (GFR), cystatin, peripheral blood levels of myeloperoxidase (MPO), malondialdehyde (MDA), and superoxide dismutase (SOD) before and after the procedure were compared between the two groups.

RESULTSThe incidence of CIN was significantly lower in high-dose atorvastatin group than in the regular dose group. At 48-72 h after the surgery, serum Scr and cystatin levels were significantly lower and eGFR was significantly higher in the high-dose group. At 24 h after the surgery, MPO and MDA levels were significantly lower, and SOD activity was significantly higher in high-dose group than in the regular dose group.

CONCLUSIONHigh-dose atorvastatin used before angiography is more effective than the regular dose in attenuating contrast agent-induced renal dysfunction, and its mechanism is related with the inhibition of oxidative stress.

Objective To investigate the status and analyze the influencing factors of structural empowerment and psychological empowerment of midwives in Suzhou.Methods Using convenience sampling,totally 309 midwives from fifteen hospitals in Suzhou were investigated with the Conditions of Work Effectiveness Questionnaire-Ⅱ (CWEQ-Ⅱ) and Psychological Empowerment Scale (PES).Results The scores of structural and psychological empowerment of midwives were (18.07±3.12) and (14.82±2.01).There was a significantly positive correlation between midwives' structural and psychological empowerment (r=0.396,P＜0.01).Hospital level and whether participate in midwifery standardization training had an impact on structural empowerment score(P＜0.05).Age,parental status,job title,salary,delivery room working hours,number of night shifts per month,and whether or not participate in teaching had an impact on psychological empowerment score(P＜0.05).Conclusion Midwives' structural and psychological empowerments are at a moderate level.Administrators should take targeted intervention to create an empowerment-allowing working environment for midwives,stabilize midwives work force,strengthen midwifery discipline construction and make full specialized features of midwives.

Objective:To evaluate the application of a 3D printed positioner for hip rotation center in total hip arthroplasty.Methods:From August 2015 to December 2017, 14 patients were treated by unilateral total hip arthroplasty at Department Ⅰ of Joint Surgery, Orthopaedics Hospital of Zhengzhou for avascular necrosis of femoral head or femoral neck fracture. They were 8 males and 6 females with an average age of 51.8 years (from 37 to 65 years). All their surgeries were assisted by a 3D printed positioner for hip rotation center. Postoperatively, the abduction and anteversion of acetabular cup and the hip rotation center were measured, the agreement between the hip rotation center of the affected side (O2) and the anatomical rotation center of the healthy side (O1) was assessed, and the function of the affected hip and complications were recorded at the last follow-up.Results:The 14 patients were followed up for an average of 18 months (from 6 to 24 months). The postoperative ordinates of O2 and O1 were respectively 19.36 mm±3.61 mm and 18.33 mm±3.41 mm while their abscissas 39.93 mm±2.97 mm and 39.99 mm±3.16 mm, indicating agreement between O2 and O1 ( P>0.05). The postoperative abduction and anteversion of the cup were within a normal range (39.3°±3.2°and 14.6°±1.2°, respectively). The last follow-up showed that their preoperative Harris hip scores (42.3±3.2) were significantly improved (94.3±4.7) ( t=2.873, P=0.002) and that 13 cases were rated as excellent and one as good. X-ray follow-up showed good position of their acetabular prostheses, no loosening of the cups or femoral prostheses, and no heterotopic ossification. Conclusion:A 3D printed positioner for hip rotation center can effectively assist reconstruction of the hip rotation center and accurate implantation of acetabular prosthesis in total hip arthroplasty.

Objective:To evaluate the application of 3D printed osteotomy template in total knee arthroplasty (TKA) for valgus knee.Methods:A retrospective analysis was performed of the 21 patients with valgus knee who had undergone TKA at Department Ⅰ of Joint Surgery, Orthopaedics Hospital of Zhengzhou from March 2016 to February 2018. They were 5 males and 16 females, aged from 62 to 78 years (average, 66.7 years). TKA was performed with the assistance of a 3D printed personalized osteotomy template for each patient. The efficacy of the personalized osteotomy templates was evaluated by comparing the femorotibial angle, knee range of motion, Hospital for Special Surgery (HSS) knee scores of the patients between preoperation and postoperation.Results:The 21 patients were followed up for a mean duration of 16.3 months(range, from 10 months to 4 years). All incisions healed by the first intention. The last follow-ups showed that their preoperative femorotibial angle 17.6°±5.7° was improved significantly to 6.3°±1.2°, their preoperative knee range of motion 71.3°±5.8° increased significantly to 102.4°±7.5°, and their preoperative HSS scores 38.2±5.7 increased significantly to 87.5±3.5 ( P<0.001). Their radiographic evaluation at the last follow-up showed stable prosthetic components with no implant loosing or osteolysis. Conclusion:A personalized 3D printed osteotomy template can be used in TKA for valgus knee, leading to accurate osteotomy, effective correction of mechanical alignment and satisfactory clinical outcomes.
