Astract:Objective To compare the clinical efficacy of minimally invasive percutaneous osteosynthesis and supercutaneous plating with closed reduction in the treatment of distal tibial comminuted fractures. Methods A total of 40 patients with close distal tibial comminuted fractures in our hospital from April 2012 to April 2014 were divided into minimally invasive percutaneous osteosynthesis group and external fixation group. External fixation group were treated by supercutaneous plating,while the minimally invasive percutaneous osteosynthesis group were treated by minimally invasive percutaneous osteosynthesis. And the operative duration,hospital stay,the time of weight loading and frac-ture healing,postoperative complications and function of ankle were compared between the two groups. Results In the supercutaneous plating group,the operative duration was (60. 17 ± 5. 64) minutes,the hospital stay was (8. 651 ± 2. 21) days,the time of weight loading was (49.26 ±9.85)days,the time of fracture healing was (13.82 ±4.23)weeks,the incidence of postoperative complications was 5.00%,and the excellent and good rates was 95. 00%. In the minimally invasive percutaneous osteosynthesis group,the operative duration was (74. 64 ± 6. 82)minutes,the hospital stay was (18. 22 ± 2. 32)days,the time of weight loading was (57. 56 ± 11. 32)days,the time of fracture healing was (17. 47 ± 2. 31)weeks,the incidence of postoperative complications was 25. 00%,and the excellent and good rates was 80. 00%. There were significant differences in operative duration(χ2 =9. 922,P=0. 007),hospital stay(χ2 =10. 48,P=0. 015),time of weight loading (χ2 =14. 618,P=0. 001) and fracture healing(χ2 =40. 16,P=0. 000) between the two groups. The AOFSA score of supercutaneous plating group was (89. 1 ± 3. 9)point,compared with (90. 5 ± 4. 1)point of minimally invasive percutaneous osteosynthesis group,and the difference was statistically significant(χ2 =0. 463,P=0. 793). Conclusion Distal tibial fractures may be treated successfully with minimally invasive plate osteosynthesis or supercutaneous plating. However,supercutaneous plating offers multiple advantages in terms of mean operative dura-tion,hospital stay,the time of weight loading and fracture healing.

To investigate the effect of recombinant human growth hormone (rhGH) on JAK2-STAT3 pathway and the growth of gastric cancer cell lines at different GHR expression status, the eukaryotic expression vector targeting human GHR (pGPU6/GFP/Neo-shGHR and pGPU6/GFP/Neo-scramble) was constructed and transfected into MGC803 cells by Lipofectamine 2000. Stable expressive cell lines were obtained by G418 screening. The expression of GHR was analyzed by Western blotting. After being stimulated with rhGH, cell growth was detected by MTT assay. Cell cycle and apoptosis were examined by flow cytometry. The components of JAK2/STAT3 signaling pathway were detected by Western blotting. There is no significant difference of GHR expression between MGC803 and pGPU6/GFP/Neo-scramble-transfected cells (named as MGC803-NC) (P > 0.05). Compared with MGC803, the GHR expression in pGPU6/GFP/Neo-shGHR-transfected cells (named as MGC803-shGHR) decreased significantly (protein decreased 50%). The cells were treated with rhGH at 0, 150 and 300 ng x mL(-1), the growth rate of MGC803 and MGC803-NC increased significantly, PI and the number of G2/M phase cells all increased significantly, and apoptosis decreased significantly. Western blotting revealed that the expression of pJAK2 and pSTAT3 was up-regulated after being treated with rhGH in MGC803 and MGC803-NC cells. In contrast, similar change was not observed in MGC803-shGHR cells. Knockdown of GHR gene may decrease the sensitivity of gastric cancer cells to rhGH, and down-regulating of components of the expression of JAK2/STAT3 signaling pathway may be the potential mechanisms.

Objective To investigate the joint effects of selective digestive decontamination (SDD) and glutamine (Gln) on preventing intestinal bacterial translocation of orthotopic piggyback liver transplantation and to observe the incidence of postoperative pneumonia in rabbit. Methods Thirty rabbits received orthotopic piggyback liver transplantation and were randomly divided into three groups (SDD group, SDD+Gln group and control group). Mixed emulsion of tobramycin, polymyxin E and nystatin were given to the rabbits in SDD group. Same dosage of the above components plus Gln were given to the rabbits in SDD+Gln group. Samples of portal vein blood, ileum tissue and lung tissue were obtained in each group at different phases during and after operation, the pathological changes of ileum tissue, the bacterial translocation in blood of portal vein and the incidence of postoperative pneumonia were detected. Results The mixing section area of intestinal blood capillaries in SDD+Gln group was smaller compared with control group (P

Objective To investigate the change in GABA receptor-activated current in dorsal root ganglion (DRG) neurons in rats with neuropathic pain. Methods Twenty adult SD rats of both sexes weighing 100-150 g were randomly divided into 2 gorups: sham operation group (group S, n = 5) and neuropathic pain group (group NP, n= 15). Neuropathic pain was induced by ligation of right L5 spinal nerve. The animals were sacrificed at 5 days after operation. The L5 DRG( neurons in group NP and L3-5 DRG neurons in group S were immediately isolated. Whole-cellpatch- clamp technique was used. The extracellular solution contained GABA 100μmol/L.The frequency and amplitude of the GABA-activated current in DRG neurons and the changes in action potential (threshold potential, rheobase and overshoot) and resting potential before and after GABA administration were recorded. Results GABA 100μmol/L induced rapid inactivation of inward current in most neurons. Compared with the baseline before application of GABA, in group S GABA induced depolarization,increased resting potential and decreased amplitude and rheobase of action potential in large and medium DRG neurons, while in group NP GABA increased resting potential but induced no significant change in threshold potential and rheobase and overshoot of action potential. The frequency and amplitude of GABA-activated current and the degree of change in resting potential and rheobase and overshoot of action potential were significantly lower in group NP than in group S.Spontaneous discharge occurred in small DRG neurons in both groups. No GABA-activated current was observed in all DRG neurons with spontaneous discharge. Conclusions Neuropathic pain is induced by decreasing GABA-mediated inhibition signals in large and medium DRG neurons leading to increased excitability of neurons.

Objective To approach a semi-quantitative diagnostic criteria of neonatal hypoxic-ischemic encephalopathy(HIE) by comprehensive scoring, including history, clinical manifestation and laboratory data,which can be used for early diagnosis,severity grading and the institution of therapy.Methods We analyzed history, clinical manifestation and some parameters of laboratory data,and established criteria for scoring and grading,and compared this grading with the grading determined by clinical data and follow-up,which brought forward a semi-quantitative diagnostic criteria, and applied this criteria to other 41 patients with HIE to test its reliability.Results The grading criteria were established as the following:if total score ≥20.0,the patient was graded as severe one;total score between 10.5-19.5, moderate one; between 5.5-10.0,mild one;≤5.0,non-HIE one. The scoring system was used in other 41 patients with HIE,the specificity and sensitivity were 100% and 96 .9%,97.2% and 100%,100% and 100%, respectively.Conclusions For severe HIE cases who are not permitted to receive compated tomography(CT) examination or no CT can be used, this scoring system can be used to diagnoze HIE and grade the severity. This method is simple and easy to perform.Both specificity and sensitivity are high for diagnosis and severity judgment of HIE.

Objective To explore prognosis and remission-related factors in lupus nephritis (LN) patients.Methods Patients diagnosed as LN by renal biopsy in Tongji Hospital Affiliated to Tongji Medical College,Huazhong University of Science and Technology between Jan 1,2011 and July 31,2016 were enrolled.All related baseline clinical data was recorded and regular follow-up was performed.Kaplan-Meier curves was used to analyze partial remission and complete remission rates.Log-rank test was performed to compare remission rates of patients with nephrotic-range proteinuria (24-hour proteinuria≥3.5 g) and without nephrotic-range proteinuria (24-hour proteinuria＜3.5 g).Univariate and muhivariate Cox regression analyses were performed to evaluate the remission-related factors in different periods.Results A total of 115 patients,with 88.7％ female and (31.5±9.5)years mean age,were followed up for up to 5 years.During follow-up period 2 patients died and 1 dialyzed.The 6-,12-,24-and 36-and 48-month renal partial remission and complete remission rates were 33.3％,58.2％,71.5％,84.0％,89.6％,and 18.9％,40.5％,67.3％,79.4％,87.0％,respectively.Patients without nephrotic-range proteinuria had higher complete remission than patients with nephrotic -range proteinuria (HR=2.01,95％CI 1.15-3.34,P=0.014),but there was no difference in their partial remission (HR=1.33,95％ CI 0.74-2.43,P=0.341).Multivariate Cox regression model indicated that every 1 g/L increase in baseline level of serum albumin was associated with increased 8％ and 9％ risk,respectively,in partial remission (HR=1.08,95％CI 1.01-1.15,P=0.024) and complete remission (HR=1.09,95％CI 1.01-1.07,P=0.038).Conclusions Around half of LN patients reach remission during 1 year.Patients without nephrotic-range proteinuria have higher complete remission,and serum albumin is a remission-related factors.
