Objective To investigate the status of nurses' resilience and to explore the related factors.Methods 1356 nurses from 11 level Ⅱ and level Ⅲ hospitals of Guangzhou were assessed by using the general information questionnaire and the Chinese version of Conner-Davidson resilience scale.Results The score of nurses' resilience was(59.99±13.59)points and it was significantly lower than that of the domestic norm.There was statistical difference of the score of nurses' resilience on different genders,educational background,professional titles,hospital level and night shifts.There was a positive correlation among educational background,night shifts and nurses' resilience,and a negative correlation between hospital level and nurses' resilience.The hospital level,night shifts and educational background were the influencing factors of nurses' resilience.Conclusions The level of nurses' resilience is low.The higher hospital level and educational background,and the less night shift,the higher of nurses' resilience.

OBJECTIVETo explore therapeutic effects of bone setting manipulation for the treatment of over degree II supination-eversion fractures of ankle,and analyze manipulative reduction mechanism.

METHODSFrom 2005 to 2008, 95 patients with over degree II supination-eversion fractures of ankle were treated respectively by manipulation and operation. There were 43 cases [11 males and 32 females with an average age of (44.95 +/- 12.65) years] in manipulation group, and 2 cases were degree II, 11 cases were degree III, and 30 cases were degree IV. There were 52 cases [21 males and 31 females with an average age of (39.96 +/- 13.28) years] in operative group,and 6 cases were degree II, 18 cases were degree III, and 28 cases were degree IV. Bone setting manipulation and hard splint external fixation were applied to manipulative group. Operative reduction internal fixation was performed in operative group. X-ray was used to evaluate reduction of fracture before and after treatment, 2 months after treatment. Ankle joint function was evaluated according to Olerud-Molander scoring system after 6 months treatment.

RESULTSAll patients were followed up with good reduction. Three cases occurred wound complication in operative group, but not in manipulative group. In manipulation group, 19 cases got excellent results, 20 cases good and 4 cases fair; while in operative group, 30 cases got excellent results, 20 cases good and 2 cases poor. There were no significant differences in fracture reduction and ankle joint function recovery between two groups (P > 0.05). Efficacy of operative treatment was better than that of manipulative treatment at degree IV fracture (P < 0.05).

CONCLUSIONBone setting manipulation is a good method for treating supination-eversion ankle joint fractures, which has advantages of simple and safe operation, reliable efficacy. For ankle join fracture at degree IV, manipulative reduction should be adopted earlier, and operative treatment also necessary

OBJECTIVETo explore the clinicopathologic characteristics, treatment and prognosis of differentiated thyroid carcinoma (DTC) in adolescents.

METHODSThe data of 46 patients with DTC under the age of 18 years were retrospectively reviewed.

RESULTSTwenty patients were misdiagnosed in this group (43.5%). All patients received operation, including 39 unilateral neck dissection and 6 bilateral neck dissection, followed by postoperative thyrotropin suppressive therapy. There were 42 cases of papillary carcinoma (91.3%) and 4 cases of follicular carcinoma (8.7%). Cervical lymph node metastasis was found in 39 cases (84.8%). In the follow-up period of 1 to 25 years (mean 10 years), no death of thyroid carcinoma occurred.

CONCLUSIONSThe most common DTC in adolescents is papillary carcinoma with better prognosis regardless of the higher incidence of cervical lymph node metastasis. The optimal extent of primary thyroidectomy and neck dissection followed by postoperative thyrotropin suppressive therapy in adolescents with DTC may improve the quality of life and decrease the incidence of complications.

BACKGROUNDGlioblastoma multiforme (GBM) is the most malignant kind of astrocytic tumors and is associated with a poor prognosis. In this retrospective study, we assessed the clinical, radiological, genetic molecular and treatment factors that influence clinical outcomes of patients with GBM.

METHODSA total of 116 patients with GBM who received surgery and radiation between January 2006 and December 2007 were included in this study. Kaplan-Meier survival analysis and Cox regression analysis were used to find the factors independently influencing patients' progression free survival (PFS) time and overall survival (OS) time.

RESULTSAge, preoperative Karnofsky Performance Scale (KPS) score, KPS score change at 2 weeks after operation, neurological deficit symptoms, tumor resection extent, maximal tumor diameter, involvement of eloquent cortex or deep structure, involvement of brain lobe, Ki-67 expression level and adjuvant chemotherapy were statistically significant factors (P < 0.05) for both PFS and OS in the univariate analysis. Cox proportional hazards modeling revealed that age or= 80, KPS score change after operation >or= 0, involvement of single frontal lobe, non-eloquent area or deep structure involvement, low Ki-67 expression and adjuvant chemotherapy were independent favorable factors (P < 0.05) for patients' clinical outcomes.

CONCLUSIONSAge at diagnosis, preoperative KPS score, KPS score change at 2 weeks postoperation, involvement of brain lobe, involvement of eloquent cortex or deep structure, Ki-67 expression level and adjuvant chemotherapy correlate significantly with the prognosis of patients with GBM.

A fluorescence enhancement probe (ZY8) for the detection of N2H4was designed and synthesized by employing 3-hydroxyflavone as a fluorophore,and its spectral properties had been investigated. The results showed that ZY8 had relatively good selectivity and specificity to N2H4in Tris-HCl-ethanol solution (9:1, V/V, pH 7.40). The fluorescent intensity of ZY8 exhibited good linear relationship with concentration of N2H4in the concentration range of 1.6×10-7mol/L-6.2×10-5mol/L,and its detection limit was estimated to be 1. 6×10-7mol/L. ZY8 itself had weak fluorescence, upon addition of N2H4, an approximate 9-fold fluorescence enhancement was observed, and the color of the solution changed from light grayish green to bright grass-green at UV light of 365 nm. So ZY8 might be used to the visual recognition of N2H4. ZY8 could detect N2H4in near-physiological pH range, and it had fast response and strong anti-interference ability. Moreover,ZY8 could be loaded as test paper for naked-eye detection of N2H4at mmol/L level in water solution,and it was also applied in the determination of N2H4in various water samples by the standard addition recovery experiments, with the recovery ratio ranged from 96.0% to 104.2% %, and RSD of all< 4%. The results of this study demonstrated that ZY8 had potential application to the detection of N2H4in the monitoring of environmental pollution.

Objective:To investigate the effects of docetaxel for postoperative chemotherapy of advanced gastric cancer.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 311 patients with advanced gastric cancer who were admitted to Lanzhou University Second Hospital from January 2013 to December 2018 were collected. There were 224 males and 87 females, aged from 26 to 82 years, with a median age of 58 years. Of 311 patients, 204 cases undergoing chemotherapy with the FOLFOX regimen (oxaliplatin, calcium folinate, 5-fluorouracil) were allocated into the FOLFOX group, and 107 cases undergoing chemotherapy with the FLOT regimen (docetaxel, oxaliplatin, calcium folinate, 5-fluorouracil) were allocated into the FLOT group. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups of patients after matching; (2) follow-up; (3) analysis of survival factors; (4) subgroup analysis; (5) adverse reactions. Follow-up was performed using a combination of outpatient examination, hospitalization review and telephone interview to detect situations of patients chemotherapy, postoperative survival, tumor recurrence and metastasis up to February 2019. The propensity score matching was realized using the nearest neighbor method with 1: 1 ratio and caliper setting as 0.02. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability method. Rank data was analyzed using non parametric Rank sum test. The survival curve and rate were respectively drawn and calculated using the Kaplan-Meier method. The survival analysis was done using the Log-rank test. Univariate analysis and multivariate analysis were conducted using the COX regression model. Subgroup analysis was done using interaction test. Results:(1) The propensity score matching conditions and comparison of general data between the two groups of patients after matching: 198 of 311 patients had successful matching, including 99 in each group. Cases with tumor differentiated as poorly differentiation or well differentiation, cases with CA19-9 <27 U/mL or ≥27 U/mL, cases with CA125 <35 U/mL or ≥35 U/mL before propensity score matching were 109, 95, 156, 48, 186, 18 in the FOLFOX group, and 42, 65, 93, 14, 104, 3 in the FLOT group, respectively, showing significant differences in the above indicators between the two groups ( χ2=5.649, 4.798, 4.039, P<0.05). After propensity score matching, the above indicators were 44, 55, 85, 14, 96, 3 in the FOLFOX group, and 42, 57, 85, 14, 96, 3 in the FLOT group, respectively, showing no significant difference in the above indicators between the two groups ( χ2=0.082, 0.000, 0.000, P>0.05). (2) Follow-up: 198 patients of the two groups after matching were followed up for 2 to 69 months, with a median follow-up time of 38 months. During the follow-up, 92 cases survived without tumor, 2 cases underwent tumor recurrence or metastasis, and 104 cases died including 103 with tumor related death and 1 case with non-tumor related death. The courses of chemotherapy were 5.6±0.7 and 5.4±0.8 for the FOLFOX group and FLOT group, respectively, showing no significant difference between the two groups ( t=1.651, P>0.05). The 1, 3, and 5-year cumulative survival rates of patients were 72.2%, 31.5%, 27.7% and 83.2%, 42.8%, 38.2% for the FOLFOX group and FLOT group, respectively. The median overall survival time were 21 months and 34 months for the FOLFOX group and FLOT group, respectively, showing significant difference between the two groups ( χ2=4.473, P<0.05). (3) Analysis of survival factors: results of univariate analysis showed that cases undergoing chemotherapy with the FLOT regimen, cases with tumor as diffuse type of Lauren classification, cases with tumor as mixed type of Lauren classification, cases with tumor differentiated as well differentiation, cases with tumor diameter≥5 cm, cases with CA19-9≥27 U/mL, cases with carcinoembryonic antigen (CEA)≥3.4 μg/L, cases with tumor as T4 stage of T staging, cases with tumor as N2 stage of N staging, cases with tumor as N3 stage of N staging, cases undergoing distal gastrectomy and cases undergoing total gastrectomy were related factors influencing postoperative survival of patients ( hazard ratio=0.659, 1.617, 1.798, 0.672, 1.726, 1.655, 1.942, 2.036, 2.536, 4.085, 1.810, 2.310, 95% confidence interval: 0.444-0.978, 1.024-2.556, 1.105-2.926, 0.457-0.990, 1.159-2.569, 1.006-2.723, 1.295-2.912, 1.190-3.484, 1.409-4.564, 2.491-6.697, 1.020-3.211, 1.261-4.233, P<0.05). Results of multivariate analysis showed that cases undergoing chemotherapy with the FLOT regimen, cases with CEA≥3.4 μg/L, cases with tumor as N2 stage of N staging and cases with tumor as N3 stage of N staging were independent risk factors influencing postoperative survival of patients ( hazard ratio=0.622, 1.732, 2.217, 4.039, 95% confidence interval: 0.418-0.926, 1.124-2.670, 1.200-4.097, 2.448-6.662, P<0.05). (4) Subgroup analysis: results of subgroup analysis showed that of the different subgroups using gender, age, tumor Lauren classification, tumor differentiation degree, tumor location, tumor diameter, tumor markers, tumor T staging, tumor N staging and surgical procedures as subgrouping index, the efficacy difference between the FLOT group and the FOLFOX group was the same (interaction P>0.05). (5) Adverse reactions: the incidence of grade Ⅲ-Ⅳ adverse reactions of leukopenia, anemia, thrombocytopenia, nausea, vomiting and liver and kidney dysfunction were 11.1%(11/99), 2.0%(2/99), 3.0%(3/99), 12.1%(12/99), 4.0%(4/99), 1.0%(1/99) and 34.3%(34/99), 1.0%(1/99), 9.1%(9/99), 24.2%(24/99), 4.0%(4/99), 0 in the FOLFOX group and the FLOT group, respectively. There were significant differences of the incidence of leukopenia and nausea between the two groups ( χ2=15.213, 4.889, P<0.05). There was no significant difference of the incidence of thrombocytopenia between the two groups ( χ2=3.194, P>0.05) and there was no significant difference of the incidence of anemia, vomiting and liver and kidney dysfunction between the two groups ( P>0.05). There was no patient in the two group withdrawal from chemotherapy as no tolerance to toxic reactions. All patients were treated with glucocorticoids, proton pump inhibitors and serotonin receptor antagonists during chemotherapy. Patients undergoing leukopenia were treated with granulocyte stimulating factor. Conclusions:Compared with FOLFOX regimen, FLOT regimen which adds docetaxel significantly prolongs the postoperative median overall survival time of patients with advanced gastric cancer. However, FLOT regimen increases the incidence of grade Ⅲ-Ⅳ adverse reactions of leukopenia and nausea.

Objective:To evaluate our self-designed guide device for Kirschner-wire placement in the surgery for paediatric fractures of supracondylar humerus.Methods:A retrospective study was conducted of the 117 children who had been treated for fractures of supracondylar humerus at Department of Orthopedics, The First People's Hospital of Huaian Affiliated to Nanjing Medical University from March 2019 to January 2023. There were 64 boys and 53 girls with an age of (5.8±1.5) years. By the Gartland classification, there were 67 fractures of type Ⅱ and 50 fractures of type Ⅲ. The time from injury to operation averaged (48.5±10.8) hours. The children were divided into 2 groups according to how their Kirschner-wires were placed. In the control group of 58 cases, external percutaneous Kirschner-wire placement was assisted using a syringe needle; in study group of 59 cases, external percutaneous Kirschner-wire placement was assisted using our self-designed guide device for Kirschner-wire placement. The operation time, rate of one-time placement of disposable K-wire, intraoperative fluoroscopy frequency, Baumann angle, carrying angle, fracture healing time, Flynn score of elbow joint function at the final follow-up, and postoperative complications were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The 117 pediatric patients were followed up for (15.3±3.2) months after operation. The operation time [(30.6±4.5) min] and intraoperative fluoroscopy frequency [(15.6±2.1) times] in the study group were significantly less than those in the control group [(40.6±7.3) min and (23.7±4.9) times], while the rate of one-time placement of disposable K-wire in the study group was significantly higher than that in the control group [84.2%(149/177) versus 32.2%(56/174)] ( P<0.05). There were no significant differences in Baumann angle, carrying angle, fracture healing time, or Flynn score of elbow joint function at the final follow-up between the 2 groups ( P>0.05). The incidence of complications in the study group (6.8%, 4/59) was significantly lower than that in the control group (20.7%, 12/58) ( P<0.05). Conclusions:Our self-designed guide device for Kirschner-wire placement is simple and convenient to use. In the surgery for paediatric fractures of supracondylar humerus, it can improve the rate of one-time placement of disposable K-wire, reduce intraoperative fluoroscopy, and decrease the incidence of complications.

Objective To understand the distribution of water iodine in the external environment of Shanxi Province, and to provide a basis for redefining and implementation of scientific iodine supplementation in iodine deficiency, iodine adequate or iodine high areas. Methods In 2012 - 2016, administrative villages (neighborhood committees)in 119 counties(cities,districts)in 11 cities of Shanxi Province were selected as the investigation units, and 1 to 5 drinking water samples were collected. Water iodine content was detected using arsenic-cerium catalytic spectrophotometry. Areas standard was designated: water iodine content < 10 μg/L as iodine deficiency areas, > 100 μg/L as iodine high areas. Results A total of 26 213 administrative villages (neighborhood committees) of 1 362 townships (towns) of 119 counties (cities, districts) were surveyed, covering 2 850.94 ten thousand people. A total of 32 766 water samples were collected and the median iodine was 5.2 μg/L. There were 18 199 villages with water iodine < 10 μg/L, accounting for 69.4% (covering 1 812.17 ten thousand people, accounting for 63.6%), 6 471 villages with water iodine 10-<50 μg/L,accounting for 24.7%(covering 787.44 ten thousand people,accounting for 27.6 %),1 166 villages with water iodine 50 - < 100 μg/L,accounting for 4.4% (covering 181.46 ten thousand people, accounting for 6.4%), 377 villages with water iodine ≥100 μg/L, accounting for 1.4%(covering 69.87 ten thousand people, accounting for 2.5%).In 1 362 townships (towns), 71.1% (969)water iodine median was<10 μg/L,24.2%(330)water iodine median was in 10-<50 μg/L,3.4%(46)water iodine median was in 50-<100 μg/L,and 1.2%(17) water iodine median was ≥100 μg/L. In 119 counties(cities,districts),there were 90 counties(accounting for 75.6%) with the water median < 10 μg/L, there were 26 counties (accounting for 21.8%) with the water median 10 - < 50 μg/L. Conclusions Most parts of Shanxi Province(or the resident population) are iodine deficiency areas, the external environment water iodine contents in the rest of the regions are different, we should adopt different iodine supplement or iodine reduction measures in regions with different water iodine levels.
