Objective To investigate the efficacy and feasibility of percutaneous puncture and catheterization sclerotherapy for the treatment of kidney cyst under ultrasonographic guidance. Methods Fifty-seven patients with simple renal cysts were divided into study group (30 cases) and control group (27 patients) according to the therapies. In study group, patients who had the cyst diameter ≤6.0 cm( 17 cases) received direct puncture sclerotherapy, while ＞6.0 cm (13 cases) received catheterization puncture sclerotherapy. In control group, patients who had performed laparoscopic surgery. Observed and compared the efficacy, hospitalization time, operative time and complications of two groups. Results Both groups had no case of recurrence after surgery. The effective rates in study group and control group were 93.3%(28/30 ) and 96.3% (26/27) respectively, and there was no statistical difference between two groups (P ＞ 0.05). The hospitalization time and operative time in study group [( 2.3 ± 1.7 ) d, ( 13.5 ± 3.7 ) min] were significantly shorter than those in control group [(5.8 ±2.2) d, (57.7 ±8.9) min] (P＜0.05); but the incidence of complications had no statistical difference between two groups (P ＞ 0.05). Conclusions Percutaneous puncture and catheterization sclerotherapy for the treatment of kidney cyst under ultrasonographic guidance has some advantages as good efficacy, less traumatic, rapid recovery and fewer complications. It is especially suitable to be used in the primary hospital.

Objective: This work aimed to construct stable MCF-7 cell sublines from which staphylococcal nuclease domain con-taining 1 (SND1) expression was interfered to analyze the effect of SND1 silencing on the proliferation and metastasis of MCF-7 cells. Methods: The lentivirus that could mediate SND1 silencing was prepared. MCF-7 cells were infected with the lentiviruses to construct stable sub-cell lines. Quantitative real-time polymerase chain reaction and Western blot analysis were employed to determine SND1 ex-pression level. MTS, wound healing, and transwell assays were applied to analyze the effect of SND1 silencing on the proliferation, mi-gration, and invasion of MCF-7 cells. Results: A lentivirus expression vector that contains sequences encoding shRNAs targeting SND1 and an shRNA negative control were successfully established. The lentiviruses (LV-SH1, LV-SH2, LV-SH3, and 和 LV-NC) were then collected and packaged. Stabilized MCF-7 sublines were prepared through infection with lentiviruses. The most efficient MCF-7 stable cell subline, MCF-SH3, was selected for SND1 silencing. Compared with the control cell, the proliferation, migration, and inva-sion potential of MCF-SH3 were significantly decreased. Conclusion: SND1 could promote the proliferation, migration, and invasion of breast cancer cells. Thus, silencing SND1 expression will inhibit such proliferation, migration, and invasion. These results indicated that the unusual expression of SND1 is associated with breast cancer and may participate in cancer progression by affecting prolifera-tion, migration, and invasion.

The 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase activity of Sclerotinia sclerotiorum is one of the multifunctional enzyme AROM activities, which catalyzes a reversible conversion of shikimate 3-phosphate (S3P) and phosphoenolpyruvate (PEP) to EPSP and inorganic phosphate, and is inhibited by the herbicide glyphosate (N-phosphonomethyl glycine). AROM protein has been purified from Sclerotinia sclerotiorum and the EPSP synthase has been analyzed. The results indicated that the optimal pH and temperature of EPSP synthase were 7.2 and 30℃ respectively. The activation energy of the heat-deactivated reaction of the enzyme was found to be 69.62 kJ/mol. Both of the substrates, S3P and PEP, were showed to inhibit the reaction rate when their concentrations exceeded 1 mmol/L and 2 mmol/L respectively. The Km of 140.98 μmol/L for PEP and 139.58 μmol/L for S3P were obtained by Dalziel equation which was a steadystate kinetic equation of the enzymatic reaction with the double substrates. The kinetic pattern of the enzyme was consistent with a sequential mechanism. Inhibition of the EPSP synthase reaction by glyphosate was competitive with respect to PEP, with the Ki 0. 32 μmol/L, and noncompetitive with regard to S3P. Activation by [ K+ ] was observed in the forward reaction. The Km (PEP) was lowered by increasing [ K+ ], while the Km (S3P) changed irregularly and the Ki (PEP) was enhanced.

Objective.To probe into the influence of Jiannao Anshen Capsule of Miao medicine on the behavioral performance,content of cytokine interleukin-1 (IL-1),neuroendocrine hormone melatonin (MT) and monoamine neurotransmitter 5-hydroxytryptamine (5-HT) of rats with sleep deprival.Methods All of the 60 rats were evenly and randomly divided into 5 groups:the normal control group,model control group,estazolam group,Zaoren Anshen group,and Jiannao Anshen of Miao medicine group,respectively.Every group had 12 rats.Sleep deprivation rat model was established by intraperitoneal injection of para-chlorophenyla lanice (PCPA).After successful modeling,the rats were intragastrically administrated with corresponding medicines.The contents of serum 5-HT,IL-1 and MT and the contents of 5-HT,MT in brain tissue were determined.Results Behavioral score,the contents of 5-HT,MT and IL-1 in serum and the contents of 5-HT,MT in brain tissue in insomnia rats caused by PCPA were significantly decreased as compared with normal control group (P ＜ 0.05).In the Jiannao Anshen group,estazolam group and Zaoren Anshen group,the behavioral score,the content of 5-HT,MT and IL-1 in serum and the content of 5-HT and MT in brain tissue of insomnia rats were significantly increased as compared with model control group (P ＜ 0.05).The behavioral score,the content of 5-HT,MT and IL-1 in serum and the content of 5-HT and MT in brain tissue of insomnia rats were not statistically significant different among Jiannao Anshen group,estazolam group and Zaoren Anshen group (P ＞ 0.05).Conclusion Jiannao Anshen capsule of Miao medicine could obviously improve the sleep quality of rats with sleep deprival.The mechanism may be related to improving the content of IL-1,MT and 5-HT.

Objective To investigate the clinical effects of phacoemulsification combined with goniosynechialysis on the treatment of primary angle-closure glaucoma (PACG) with cataract. Methods The retrospective review included 71 patients (98 eyes) with PACG and cataract treated in Tianjin Huanghe Hospital. Patients were underwent phacoemulsification and intraocular lens implantation combined goniosynechialysis. Among these patients, there were 21 males (30 eyes) and 50 females (68 eyes). Patients ranged in age from 53 to 94 years old, everage (73.94 ± 6.43) years old. They were divided into acute angle-closure glaucoma with cataract group (47 patients, 64 eyes) and chronic angle-closure glaucoma with cataract group (24 patients, 34 eyes). The visual acuity, intraocular pressure (IOP), anterior chamber angle, anterior chamber depth (CCT), topical and oral medications and surgical complications were observed before and after surgery in two groups. All the patients were followed up for 6 months. Results At the end of follow-up, postoperative visual acuity, IOP, CCT, anterior chamber angle and IOP-lowing medicine (topical and oral medications) were all improved in the two groups compared with those of preoperative levels (all P < 0.01). There were no statistical differences in preoperative or postoperative average visual acuity, IOP and anterior chamber angle between two groups (all P > 0.05). Values of CCT were significantly higher before and after operation in chronic angle-closure glaucoma with cataract group than those of acute angle-closure glaucoma with cataract group (P < 0.05). No drug-control rate of intraocular pressure was 76.5% (26/34) for chronic angle-closure glaucoma with cataract group than that of acute angle-closure glaucoma with cataract group (100%, 64/64). There was no need on topical medication in acute angle-closure glaucoma with cataract group. There were 14 eyes had corneal edema and 8 eyes appeared iris fibrous exudation in two groups, while no other serious complications. Conclusion For patients with PACG and cataract, the combined surgery of phacoemulsification and goniosynechialysis is a safe and effective therapy that can improve visual acuity and reduce IOP with fewer complications.
