Objective To investigate the efficacy and safety,as well as surgical essentials of upper urinary tract calculi (calculi being≤2 cm in diameter) complicated with pre-surgical uncertain pyonephrosis through one-stage renal calculi removal by percutaneous nephrolithotomy and suction device.Methods Retrospective analysis was used to detect the thirty-three cases with upper urinary tract calculi complicated with pre-surgical uncertain pyonephrosis collected from August 2010 to March 2016 in Yellow River Sanmenxia Hospital Affiliated to Henan University of Science and Technology,all the cases in the group had no pre-surgical fever,no apparent infection by blood-urine routine test,different degrees of hydronephrosis and no indications of pyonephrosis confirmed by CT and color Doppler ultrasonography,no pre-surgical anti-infection cure,pyonephrosis was found during the operation.First of all,a suction device was used to suck pus through percutaneous renal channel,rinsing repeatedly with small amount of fluid until the sucked rinsing fluid was clear;then,the one-stage calculi was removed by percutaneous renal lithotripsy,and the pus was sent to be cultured during the surgery,and the cases were treated by postoperative intravenous anti-infection for seven to seventeen days.Operation condition,postoperative blood routine,temperature,calculi removal and other clinical recovery conditions should be carefully observed.Results All the 33 cases underwent the one-stage single channel percutaneous nephrolithotom,the surgery was successful,the operation lasted 28-59 minutes,with an average of 41 minutes per case.Within the first-week of operation,CT reexamination showed the stone-free rate was 90.9% (30/33),and three cases had residual stone,the maximum diameter was about 6mm;seven cases had high fever within 3 days after the surgery (21.2%),and the temperature in four cases was higher than 38.5℃(12.1%) and two cases had fever within 3-6 days after surgery (6.1%),the highest temperature reached 38.0℃,and no fever existed after 6 days.Compared with preoperative values,the postoperative blood routine indicated that the surgery-relevant hemoglobin has decreased to (6.16±5.21) g/L;three days after surgery,white blood cell count was (7.16±4.86) 109/L.There were no severe complications such as sepsis,septic shock,renal abscess,hemorrhage.All cases were followed up for 6 to 36 months and no secondary pyonephrosis or renal dysfunction occurred during that period.Conclusion The treatment of upper urinary tract calculi,complicated with pyonephrosis without pre-surgical fever through one-stage renal calculi removal by percutaneous nephrolithotomy and suction device is effective and safe,it can be used as the routine method in basic hospitals and more attention should be paid to the operation and renal pelvic pressure in order to avoid the occurrence of complication.

Objective: To explore the eff ect of Fasudil on the invasion and metastatic abilities of human high metastatic liver cancer cells (HCCLM3) and the underlying mechanisms. Methods: HCCLM3 cells were incubated with 100 μmol/L Fasudil. Fluorescence staining forF-actin and Transwell assay were performed to observe the invasion ability of HCCLM3 cells. HCCLM3 cells were divided into 3 groups: a negative control group, a Fasudil group and a BTB/POZ domain containing 7 (BTBD7)-siRNA group. Western blot assay was performed to detect the expression levels of BTBD7, ras homolog family member C (RhoC) and Rho-associated, coiled-coil containing protein kinase 2 (ROCK2), matrix metalloproteinases 2 (MMP2) and MMP9. Zymogram analysis method was performed to detect the expression activities of MMP2 and MMP9. hTe BTBD7-siRNA group was served as a positive control. Results: In HCCLM3 cells treated with Fasudil, the invasion ability was significant decreased compared with the control group, concomitant with the down-regulated expression levels of BTBD7, RhoC and ROCK2 protein as well as the decreased activities of MMP2 and MMP9. Conclusion: Fasudil plays an important role in interfering BTBD7-ROCK2 signaling pathway and suppressing the invasion and metastasis of hepatocellular carcinoma.

Objective To summarize our experience on the diagnosis and treatment of gastric smooth muscle tumor.MethodThe clinical data of 34 cases with gastric smooth muscle tumor were analyzed retrospectively.ResultLeiomyosarcomas were ≥5 cm in diameter in 68% of all cases, and ≥10 cm in 50%. Most leiomyosarcomas were located in the fundus and corpus of the stomach (94%). Some patients of gastric leiomyosarcoma have the triad of epigastric pain, mass, and bleeding. Gastroscopy examination often reveals a mass lying submucously. Total or partial gastrectomy was performed for all patients based on tumor size and locus. The 3, 5, 10-year′s survival rate were 87%, 52% and 26% respectively. Conclusion Most gastric leiomyosarcomas are characteristic of local invasiveness, postoperative survival is often favourable.

Objective To evaluate the role of routine delayed percutaneous coronary intervention (PCI) after thrombosis in the management of patients with ST-segment elevation myocardial infarction. Methods Ninety-eight patients with STEMI who underwent routine delayed PCI after thrombosis and other 82 patients with STEMI who were given conservative strategy after thrombolysis were enrolled in this study and were investigated during their in-hospital period and 6-month follow-up regarding major adverse clinical events (MACE) and the cardiac structure and function by echocardiography. The patients were divided into the control group (conservative strategy after thrombolysis), therapy group 1 (routine delayed PCI after successful thrombolysis), and therapy group 2 (routine delayed PCI after unsuccessful thrombolysis). Results Compared with conservative strategy after thrombolysis, routine delayed PCI after thrombosis decreased in-hospital mortality (4.9% vs 0%, 0%), shortened average hospital stay (25.3 days vs 13.5 days, 15.1days), decreased the need for revascularization for target lesion (7.3% vs 0%, 0%) and lowered the incidence of thrombosis or infarction (7.3% vs 0%, 0%), and also produced lower mortality (13.4% vs 1.4%, 0%), prevented reinfarction (12.2% vs 4.2%, 4.5%) and stroke (2.4% vs 0%, 0%), decreased the need for revascularization for target lesion (28% vs 4.2%, 4.5%) and prevented further left ventricle remodling. Conclusion Routine delayed PCI after thrombosis may to prevent recurrent ischemia, reinfarction, and reocclusion, so as to improve immediate results and 6-month prognosis.

As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

Objective To study microsatellite instability(MSI) in multiple primary colorectal carcinoma(MPCC) and solitary colorectal tumor(SCT), and to explore the relationship between the expression of mismatch repair(MMR)、p53、Bax、PCNA and MSI. Methods The expression of MMR、p53、Bax、 PCNAwere detected by immunohistochemical staining, and MSI at five microsatellite loci were examined by PCR-SSLP in 51 tumors from 38 MPCC patients and 35 SCT cases. Results The replication errors positive phenotype was observed in 27 of 51(53%) tumor foci from MPCC cases, and in 6 of 35(17%) SCT cases. There was an inverse correlation between replication errors (RER) positive and expression of p53; the PCNA labeling index of RER positive tumors were significantly lower than of RER negative tumors; RER positive related strongly with poor differentiation, the proclivity for proximal colon. Conclusions MSI may play an important role in the development of MPCC and may be used as a tumor marker of MPCC.

BACKGROUND:Children usually wear school bags when walking, and overweight school bags do harm to the lower extremity and foot, thus affecting the child development. OBJECTIVE:To investigate the effect of obesity on gait characteristics of children wearing school bags during walking. METHODS:Forty pupils were enrolled in accordance with body mass index and China school-age children and adolescents overweight, obesity screening body mass index classification standard, including 20 obese children (body mass index: (28.13±3.4) kg/m2) and 20 non-obese ones (body mass index: (17.44±1.57) kg/m2). The gait parameters of children wearing school bags during walking were measured using a 2-m Footscan Plantar Pressure Plate System from RSscan International. RESULTS AND CONCLUSION: Compared with the non-obese children, the peak pressures under the metatarsal heads II-V, midfoot and heel lateral were significantly higher in obese children wearing school bags during walking (P < 0.05). The time to peak pressures under the toes II-V, the metatarsal heads IV, V and midfoot was also significantly higher (P < 0.05). In addition, the arch index for the foot, and right foot axis angle were significantly larger in the obese children as compared with the non-obese children (P < 0.05). To conclude, obese children wearing school bags during walking have weaker walking stability with flatter foot pattern, the larger foot axis angle and dynamic plantar pressure distribution changes compared with non-obese children, which can result in foot damage.
