Objective To evaluate the safety and efficacy of ultrasound-guided transperitoneal PCNL for treatment of renal calculi in pelvic ectopic kidney.Methods The clinical data of 4 cases of pelvic ectopic kidney treated in our hospital from June 2016 to August 2017 were retrospectively analyzed.The patient's age ranged from 30 to 67 years with an average of 47.25 years.There were two male and two female patients.2 cases suffered with left pelvic ectopic kidney stones.One case had right pelvic horseshoe ectopic kidney stones and one case had spinal deformity left pelvic ectopic kidney stones.Multiple stones were found in 2 cases.The mainly stones located in the renal pelvis in one case.Multiple stones in the lower calyx was found in another case.The remaining 2 cases had single stones in the renal pelvis.Stone size was 3.4 cm × 2.1 cm,3.0cm×2.1 cm,2.8 cm×2.4 cm and 2.1 cm×1.9 cm respectively.And 1 case with renal calculi in left pelvic ectopic kidney had a history of open surgerv 11 years ago because of the same situation with pelvic ectopic kidney calculi.In this study,all operation was performed under general anesthesia.The ultrasound-guided percutaneous nephrolithotomy combined with preoperative CTU and intraoperative color Doppler ultrasound was used to find the target renal calyx or renal pelvis.And a certain pressure was applied to the abdominal wall to make the intestinal canal deviate from the surface of the pelvic ectopic kidney as much as possible.Under ultrasound real-time detection,it was punctured into the target renal calyx or renal pelvis to find and break stones.And F6 double J tube and F18 nephrostomy tube were left.Operative and post-operative related details (stone free,bleeding,abdominal infection) were reviewed.Results Stone free rate were 100％ (4/4).The time of operation and hospital stay were 62,59,55,51 min and 6,6,5,5 days,respectively.None had significant intraoperative and postoperative complications,including haemorrhage,injury of mesenteric vessels,abdominal infection and hydrops.No one left residual stones during 1 month and 3 nonths of follow-up.Conclusions The ultrasound-guided transperitoneal PCNL is a safe and effective procedure for the treatment of patients with renal calculi in pelvic ectopic kidney.

Objective:To explore the effects of the continuous nursing model on the prognosis, outcome and quality of life of patients with systemic lupus erythematosus (SLE) .Methods:Totally 175 SLE inpatients admitted in the Department of Rheumatology and Immunology in Guangdong Second Provincial General Hospital from January 2016 to September 2019 were selected by convenient sampling and divided into the experimental group ( n=84) and the control group ( n=91) . Patients in the experimental group received continuous nursing care, while patients in the control group received routine care for 3 months The Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) , Systemic Lupus Erythematosus Knowledge Questionnaire (SLEKQ) , MOS SF-36 Health Survey (SF-36) , readmission rate and nursing satisfaction rate were compared between the two groups. Results:After intervention, the patient knowledge and patient's perception of family knowledge scores in the SLEKQ of the experimental group were higher than those of the control group, whereas the SLEDAI-2K score was lower in the experimental group than in the control group, and the differences were statistically significant ( P< 0.05) . After intervention, the scores of all SF-36 dimensions in the experimental group were higher than those in the control group, and the differences were statistically significant ( P < 0.05) ; the readmission rate of the experimental group was lower than that of the control group, and the difference was statistically significant ( P<0.05) ; the nursing satisfaction of the experimental group was higher than that of the control group, and the difference was statistically significant ( P< 0.05) . Conclusions:The implementation of the continuous nursing model can more effectively improve the disease awareness of SLE patients, improve the health-related quality of life, and reduce the readmission rate.

Screening out the safety-related substances and establishing the corresponding standard has been a key research issue to improve the safety of traditional Chinese medicine injections(TCMIs). 5-HMF which widely exists in sugar-containing TCMIs has long been considered as an important safety-related substance. In this review, we summarizes the research progress on the toxicology of 5-HMF as well as the content and standards of 5-HMF in TCMIs.Therein, both literature summary and analysis results indicate that there are lack of toxicology researches of 5-HMF and its metabolites in TCMIs, although the potential toxicity of 5-HMF and its metabolites has been reported. Moreover, the content of 5-HMF largely varies from TCMIs to TCMIs, and even in the same TCMIs from different factories. To ensure the clinical efficacy of TCMIs, it urgent to carry out the study of the toxicology of 5-HMF in TCMIs comprehensively and systematically, so as to set up a relatively uniform standard as well as to develop process quality control method.

OBJECTIVE: To investigate the incidence of neonatal asphyxia and possible contributing factors for the development of severe asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture, China. METHODS: A total of 16 hospitals in Hubei Enshi Tujia and Miao Autonomous Prefecture were selected as research centers. A retrospective analysis was performed for the clinical data of 22 294 live births in these 16 hospitals from January to December, 2016 to investigate the incidence rate of neonatal asphyxia and possible contributing factors for the development of severe asphyxia. RESULTS: Of the 22 294 neonates born alive, 733 (3.29%) were diagnosed with neonatal asphyxia, among whom 627 had mild asphyxia and 106 had severe asphyxia. The neonates with low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight had a higher incidence of severe asphyxia (P<0.05). CONCLUSIONS The incidence rate of neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture is higher. Low maternal education level, maternal anemia during pregnancy, chorioamnionitis, abnormal amniotic fluid, abnormal umbilical cord, placenta previa, placental abruption, Tujia Minority, preterm birth, and low birth weight may be related to the development of severe neonatal asphyxia.

ObjectiveTo simulate the microstructure and mechanical properties of tendon tissue and promote its regeneration and repair, electrospinning technology was used to prepare L-polylactic acid (PLLA) fiber membranes loaded with different nano zinc oxide contents and with oriented structures. Physical and chemical characterization and biological performance evaluation were carried out to explore their effects on tendon cell proliferation and differentiation. MethodsPreparation of PLLA fiber scaffolds and PLLA/ZnO fiber scaffolds containing different mass fractions of nano ZnO was performed using electrospinning technology. The physicochemical properties of the scaffold were characterized by scanning electron microscopy, mechanical stretching, and EDS spectroscopy. The scaffold was co-cultured with mouse tendon cells to detect its biocompatibility and regulatory effects on cell differentiation behavior. ResultsThe fiber scaffolds were arranged in an oriented manner, and zinc elements were uniformly distributed in the fibers. The tensile strength and Young’s modulus of PLLA/0.1%ZnO fiber scaffolds were significantly higher than PLLA fiber scaffolds. The number of cells on the surface of PLLA/0.1%ZnO fiber scaffold was significantly higher than that of the PLLA group, and the activity was better; mouse tendon cells exhibit directional adhesion and growth along the fiber arrangement direction. ConclusionThe oriented PLLA/0.1%ZnO fiber scaffold had excellent physicochemical properties, which can significantly promote the oriented growth, proliferation and differentiation of tendon cells. It is expected to be used for tendon tissue regeneration and repair in the future.

OBJECTIVETo explore the mental health status of residents scattered living in Anxian after Wenchuan earthquake so as to provide scientific basis for further mental health intervention.

METHODSA face to face interview was conducted among the scattered residents with designed questionnaire, which had three parts of the physical and emotional reaction, the relax methods and the social care and supports expected. Two-stage probability proportional to size (PPS) sample method was performed to sample 2184 from 0.44 million scattered residents in Anxian. On the basis of statistical description, mental health of different characteristics groups was compared.

RESULTSThree main symptoms of posttraumatic stress disorders in 2184 residents (11.23+/-3.44) were higher than the 103 fire victims in Hunan in 2003 (10.06+/-3.26), three factor scores of SCL-90 (5.76+/-1.74) were higher than normal in 1998 repair mode (n=23 891) (4.72+/-1.44), and the statistical difference was observed (t=10.77, P<0.05; t=706.04, P<0.05). Comparing the mental health of different groups, some significant differences were found by age, gender and education background.

CONCLUSIONThe earthquake disaster brought prevalent physical and emotional reaction. Elderly people, female, junior students need mental intervention immediately. Therefore, strengthen the mental education and assistance (especially in high risk groups) would be of more significance.
