Infantile spasms constitutes an unique,age-specific epilepsy syndrome of early infancy characterized by epileptic spasms often accompanied by neurodevelopmental regression and an electroencephalograph finding of hypsarrhythmia.For the complex and various etiologies,the pathogenesis remains unclear.Although the relevant guidelines and consensuses are being updated all the time,but proven therapies are still limited because of efficacy,tolerability,at times even availability.In this paper,the current findings regarding up-to-date advances in the treatment of infant spasms were reviewed,especially in use of the corticosteroid and vigabatrin as well as the quality-of-care indicators for infantile spasms.

Objective: To explore the possible relationships of adolescent personality traits, personality deviation and parental rearing pattern. Methods: 393 students from a high school in ShanDong were tested by PACL and EMBU. Re- sults: Generally, adolescent personality traits showed different profiles while factors of EMBU varied in different levels; Antisocial personality deviation was greatly influenced by parental warmth and understanding factor, father's punishment and rigor, father's overprotection. Schizoid personality deviation was mainly influenced by parental warmth and under- standing. Passive- aggressive personality dysfunction was influenced by father's warmth and understanding. Conclusion: Adolescent personality deviation is greatly influenced by parental rearing.

Objective To investigate the role of vitamin D receptor (VDR) in the protection of bufalin on podocyte injury induced by adriamycin (ADR).Methods (1) In vitro:the toxic effect of different concentrations of bufalin (10-9,10-8,10-7,104 mol/L) on podocyte was evaluated by lactate dehydrogenase (LDH) test;Annexin V-FITC and RT-PCR were utilized for podocyte apoptosis and VDR mRNA level respectively.Western blotting was used to analyze the protein expression of VDR and nephrin.SiRNA intervene was also applied to evaluate the role of VDR in bufalin's protective effect on podocyte injury induced by ADR.(2) In vitro:24 SD rats were randomly divided into three groups:control group,ADR group and ADR+bufalin group.TUNEL assay was applied to detect the apoptosis of podocytes in the kidney.Immunofluorescence and transmission electron microscope (TEM) were applied to analyze the expression of VDR and the ultrastructure of the glomerulus.Results Bufalin concentration lower than 10-7 mol/L had no toxicity on normal podocyte.Bufalin reduced the urinary protein excretion (P ＜ 0.05),alleviated the removal of podocyte foot processes and attenuated the changes in nephrin expression in the glomerulus of the adriamycin (ADR) rats (P ＜ 0.05).Bufalin notably inhibited the down-regulation of VDR in protein levels on the glomerulus of the ADR rats.Additionally,bufalin inhibited the down-regulation of VDR in both mRNA levels and protein levels (P ＜ 0.05),nephrin protein expression (P＜ 0.05),and apoptosis induced by ADR in cultured podocytes.Additionally,VDR specific siRNA intervene abolished the protective effect of bufalin in ADR-induced podocyte injury.Conclusion Bufalin can alleviate ADR-induced podocyte injury via enhancing VDR expression.

A rapid, sensitive, label-free and separation-free analytical method for determination of melamine ( MA) was developed based on surface enhanced Raman scattering ( SERS ) effect of gold nanoparticles. Through tri-sodium citrate reduction method, gold nanoparticles with average diameter of 30 nm were obtained. The melamine detection platform was constructed after self-assembling 4-mercapto phenylboronic acid (4-MPBA) on the surface of gold nanoparticles through Au S covalent bond. When MA existed in solution, 4-MPBA functionalized gold nanoparticles would aggregate because of strong hydrogen bond interaction between MA and 4-MPBA. Moreover, following increase of the concentration of MA, gold nanoparticles would aggregate more intensively and form more hot spots. As a result, Raman signal of 4-MPBA and MA was enhanced greatly. The characteristic Raman peaks of 4-MPBA and MA respectively located at 1076 cm-1 and 715 cm-1 . Hence, the qualitative and quantitative detection for MA were realized based on the ratio value of I715 cm-1 to I1076 cm-1 . The linear range of MA detection was 0 . 1 μmol/L-1. 5 μmol/L. The limit of detection (LOD) reached 0. 02 μmol/L in terms of three times signal to noise.

ObjectiveTo evaluate term efficacy of focal cryoablation for localized single lesion prostate cancer and the protection of erectile function.MethodsFrom June 2008 to December 2009, 12 patients with localized single lesion prostate cancer were treated with focal cryoablation. All diagnoses were confirmed by transrectal ultrasound-guided prostatic biopsy. The mean Gleason score was ≤ 7; three cases had a Gleason score of 5, five cases a score of 6, and four cases a score of 7. The average preoperative value of PSA was 9.7 ng/ml ( 4.2 - 14.9 ng/ml ). The PSA level was obtained every three months for the first year and then every six months thereafter. Patients with a PSA nadir greater than 1.0 ng/ml or if the PSA nadir increased more than 2 ng/ml underwent repeat biopsy to exclude tumor recurrence.ResultsThe mean operative time was (82 ±26) minutes. The mean postoperative hospital stay was (5 ± 2) days. After catheter removal, all 12 cases had good continence and 10 had erectile function before surgery. Of the 10 patients, eight had erectile function after surgery. The follow - up ranged from 12 to 30 months ( mean 23 ).The lowest average serum PSA nadir was 2.2 ng/ml, nine patients had a minimum PSA nadir of less than 1.0 ng/ml and three had a minimum PSA nadir of more than 1.0 ng/ml. Four patients underwent repeat biopsy after abnormal PSA, and prostate cancer was detected in the contralateral gland in one patient.ConclusionsUltrasound-guided transperineal focal cryoablation is a safe and effective treatment with few complications for localized single lesion prostate cancer. Additional studies with longer follow-up are necessary for long-term efficacy.

Objective To evaluate the olfactory function and its influence factors by using Sniffin ’ Sticks test, and to compare the quality of Parkinson ’s disease (PD) recognition between Sniffin’ Sticks and 16 kinds of odor identification in Sniffin ’ Sticks(SS-16) tests.Methods The Sniffin’Sticks test was used to assess the olfactory function of 68 PD patients and 76 healthy volunteers , and the relationship between smell and age, disease duration, Unified Parkinson’ s Disease Rating Scale score, Hoehn-Yahr (H-Y) rating, and cognitive function level (Montreal Cognitive Assessment) was analyzed.Results (1)The prevalence of olfactory dysfunction in PD group (83.3%) was significantly higher than that in control group (21.2%).The Sniffin’ Sticks test showed that the odor threshold score (6.6 ±3.2, P=0.000), odor discrimination score (6.6 ±3.3, P=0.000), 16 kinds of odor identification score (6.8 ±2.4, P=0.000) in PD group were significantly lower than those in control group.( 2 ) When comparing the PD cases and healthy controls in recognition , the sensitivity and the specificity of the Sniffin ’ Sticks test were 0.897 and 0.737, respectively, similar to the SS-16 test.However, the Sniffin’ Sticks test showed advantage compared with odor threshold and odor discrimination.( 3 ) The olfactory score in PD group was positively correlated with cognitive function (r=0.243, P=0.046), and was unrelated with age, gender, disease duration, and disease severity.The olfactory score in control group was negatively correlated with age (r=-0.270, P=0.018), but positively correlated with cognitive function (r=0.281, P=0.014).Conclusions There is a higher incidence of olfactory dysfunction in PD patients than in control group.Sniffin’ Sticks test is superior to SS-16 test in quantitative and qualitative analysis of olfactory function in PD patients.Two tests both have high sensitivity and specificity in the recognition of PD .

The effects of waveform and frequency on proliferation of human lung adenocarcinoma cell line A549 were studied by FX-4000 strain unit . The results showed that cellular proliferation index (PI) reduced significantly in squarewave group when compared with the control after A549 cells were subjected to collagen I 0-25% elongation at frequency 20 cycles/min, 40 cycles/min and 60 cycles/min for 2h. The PI showed no distinct difference in trianglewave group. The PI increased in heartwave group. These data indicate that A549 cells do respond to physiological strain in vitro. The effects of squarewave and 60 cycles/min tension may be optimal for inhibiting the proliferation of A549 cells. To select appropriate waveform and frequency will be of paramount importance to inhibiting proliferation of A549 cells.

Objective To present the technique and short-term results of retroperitoneal laparoscopic renal cryoablation for small renal tumors. Methods Ten selected patients cases with 11 renal tumors were included in present study. There were 3 cases of left renal tumor, 6 cases of right renal tumor and 1 case of bilateral renal tumors. Tumors were located at the upper pole (2), middle (6), or lower pole (3). All tumors were located distant from the collecting system, without evidence of metastatic disease. Mean tumor size was 2. 8 cm (range: 1.5-4.0). All the patients were managed with a double freeze-thaw cycle of retroperitoneal laparoscopic renal cryoablation. The preoperative Hb was (137± 21)g/L, ESR was (27±12)mm/1 h, SCr was (92±41)μmol/L, GFR was (42±10)ml/min.All the patients were taken routine biopsies. Results Cryoablation was technically successful in all 10 patients (11 tumors). The mean time of the operations was (101 ± 31) min, and the mean blood loss was (42±21) ml. None of the cases received blood transfusion post-operation. No operative complication was seen. The postoperative hospital stay was (4±2) d. The postoperative Hb was (129 ±18)g/L,ESR was (31±14)mm/1 h,SCr was (95±39)μmol/L,GFR was (40±11)ml/min. There was no statistic change of Hb, ESR, SCr and ECT-GFR after operations(P＞0. 05). The biopsy results revealed that 8 tumors were renal clear cell carcinomas, and 2 tumors were papillary renal cell carcinomas, and 1 tumor was renal angiomyolipoma. All the patients had a minimum follow-up of 6 months (mean 16, range 6 to 21). Follow-up magnetic resonance imaging at 1, 3, and 6 months identified the punched-out, nonenhancing, spontaneously resorbing, renal cryolesions. Follow-up biopsie of the cryoablated tumor site was negative in the only patient who have undergone the biopsy. No evidence of local or port-site recurrence was found, and no metastatic disease. ConclusionsRetroperitoneal laparoscopic renal cryoablation for small renal tumors could be an accurate and effective intervention with a relatively low incidence of complications. Critical long-term data regarding laparoscopic renal cryoablation are awaited.

Objective To evaluate the safety and short-term efficacy of transrectal ultrasound-guided transperineal cryosurgical ablation(TRUSCSA) for localized prostate cancer. Methods The data of 26 patients who were diagnosed with clinically localized prostate cancer (T_(1a)N_0M_0 - T_(2x)N_0M_0) by biopsy were reviewed. The data of serum prostate-specific antigen (PSA) level, clinical stage and Gleason score were collected. The Gleason score of all cases was ≤7; among them 6 cases were 2 - 4 and 20 cases were 5 - 7. The average pretreatment value of PSA was 11. 9 ng/ml (4. 7 - 19. 2 ng/ml). All the patients were treated with TRUSCSA, with a dual freeze-thaw cycle by using ultrathin 17-gauge cryoneedles. Immediate and delayed morbidities were evaluated. The PSA level was obtained every 3 months for the first 2 years and then every 6 months thereafter, and failure was defined as the inability to reach a nadir of 0. 5 ng/ml or less. All patients were strongly encouraged to undergo routine biopsies despite a stable PSA level. Results The operative time was (102±32)min. The postoperative hospital stay was (6±2)d. After withdrawal of the catheter, 22 cases had good continence) 4 had temporary incontinence for 3 - 7 d. Before operation 9 cases had normal sex life, and among them 5 cases had erectile dysfunction after operation. No one developed urinary retention or urethro-rectal fistula. The follow-up ranged from 6 to 30 months (mean 22). The PSA level at the last follow up visit was less than 0. 5 ng/ml in 23 patients (88%) and 0. 5 ng/ml or more in 3(12%). Postoperative biopsies were taken in 20 cases and the results were negative at the 6th month. Conclusions Transrectal ultrasound-guided percutaneous cryosurgical ablation for clinically localized prostate cancer could be effective and safe. Additional studies with longer follow-up are necessary to determine the sustained efficacy of this procedure.
