OBJECTIVETo compare the early clinical effects of Activ C cervical disc replacement (ACDR) and anterior cervical discectomy and fusion (ACDF) in treating single-level cervical spondylosis.

METHODSThe clinical data of 76 patients with single-level cervical spondylosis underwent surgery from July 2009 to September 2012 were retrospectively analyzed. Among them, 28 patients were treated with ACDR (ACDR group), including 18 males and 10 females, aged from 32 to 62 years old with an average of (45.2±6.2) years; and 48 patients were treated with ACDF (ACDF group), including 28 males and 20 females, aged from 33 to 60 years old with an average of (45.8±6.4) years. Visual analogue scale (VAS), Japanese Orthopedics Association (JOA) score, Short Form-36 (SF-36), imaging data were used to assess the clinical effects after operation.

RESULTSA total of 76 patients were followed up from 6 to 24 months with an average of 13.2 months. VAS of neck pain and brachialgia were improved in all patients after operation (P<0.05), there was no significant difference between two group (P>0.05). Somato-score and psycho-score of SF-36 of two groups were obviously increased (P<0.05), ACDR group was better than that of ACDF group (P<0.05). In ACDR group, there was no significant difference in the range of motion of surgical segments and adjacent segments between preoperative and postoperative (P>0.05); heterotopic ossification around the edge of vertebral body occurred in 1 case on the 6th month after operation, no fusion was found on the 1st year after operation. In ACDF group, the adjacent vertebral disease occurred in 1 case and the patient underwent the reoperation.

CONCLUSIONActiv C cervical disc replacement can reduce the degeneration of adjacent segments and its early outcomes for the treatment of single-level cervical spondylosis are satisfactory, but the long-term effects still need study.

OBJECTIVESTo supply clinical data for drug selextion in the treatment of erectile dysfunction through intracavernosal injection.

METHODSFifty-six ED patients were randomly classified into 2 groups and received phentolamine along with papaverine (for group 1) or phentolamine, papaverine and ligustrazin hydrochloride(for group 2).

RESULTSPatients in group 2 enjoyed a longer time of erection. More patients in group 2 succeeded in having enough erection time and hardness to complete sexual intercourse (P < 0.05).

CONCLUSIONSThe extrainjection of ligustrazin hydrochloride injection can help prolong erection duration and hardness and reduce tubercles that might occur in the corpus carvernosal. Therefore it is a safe and inexpensive drug in the intracarvernous injection treatment.

Objective To investigate the operative indication,timing,method,selective standards of fetieided fetus and the number of reduced fetuses of selective multifetal pregnancy reduction in second trimester,and the pregnancy outcome of multifetal pregnancy by this operation.Methods Trans-abdominal selective multifetal pregnancy reductions in 37 cases of multiple pregnancy (twins 6 cases,triplets 21cases, quadruplets 8 cases,and quintuplets 2 cases) during 12~(+1) -25 weeks were performed under ultrasound guidance.The fetus to be reduced was injected potassium chloride (KC1) intraeardiacally until the fetal heartbeat stopped gradually.Totally 46 fetuses were reduced.Periodic prenatal examination and monitoring of coagulation function were carried out after the procedure.The pregnancy complications and pregnancy outcome of all cases were recorded.Results (1) The successful ratio of reduction was 100% (46/46 fetuses) and the successful pregnancy ratio was 88.9% (24/27).(2) Among all the 37 cases,fifteen deliveried after 36 weeks,seven deliveried in 32-36 weeks,three deliveried in 28-32 weeks,two aborted after feticide,and ten cases were in pregnancy at the time of this study.The mean gestational age of all was (34.9?4.1) weeks,and the delivery ratio after 28 weeks was 92.6% (25/27).(3) The mean birth weight of singletons was (3014?640) g,and of twins was (2557?573) g.The neonates of three triplets all died except for in one case two fetuses were alive.(4) Except in two cases after reducing one fetus of monoamniotie twins,another one died within 24 hours,the remaining fetuses were all alive.(5) Pre- eclampsia occurred in three cases.None of the cases had blood coagulation disturbances.Conclusion (1) Selective muhifetal pregnancy reduction in second trimester can feticide the abnormal fetus objectively or reduce the fetal number effectively.It is a safe procedure to decrease the complications of multifetal pregnancy and increase the birth weight.(2) ff the intention is reducing the fetal number,we choose the fetus who lies in the fundus uteri and reduce the muhifetal pregnancy to twins.(3) It is advised to aviod performing the procedure during vaginal bleeding.We reduce fetus after vaginal bleeding stops for one or more weeks.(4) Selective second-trimester multifetal pregnancy reduction will not result in the disturbance of blood coagulation and the death of remaining fetus.The incidence of pre-eclampsia is decreased after muhifetal pregnancy reduction.

Objective To investigate the renal function changes of the children with breast milk jaundice(BMJ) and effect of early interference treatment on renal function. Methods Serum bilirubin and urine - minim protein (?2-MG,?1-MG, Alb and IgG) of the 50 patients with BMJ were measured when they were in hospital within 12 hours and the last day separately , at the same time, 20 healthy newborns had been chosen to serve as control group. Results Compared with control group, the urine minim protein of treatment group increased with the rise of serum bilirubin. When serum bilirubin was 205.2 - 256.5 ?mol/L, urine ?2- MG had mild increasing (P

Objective: To study the mutation of ENG, ACVRL1, and SMAD4 genes in one of a family of hereditary hemorrhagic telangiectasia (HHT) and explore its molecular pathogenesis. Methods: A family spectrum of a patient with a clinical diagnosis of HHT was surveyed. Peripheral blood samples from proband and their eldest were collected, and ENG, ACVRL1 and SMAD4 gene analysis was performed by chip capture high-throughput sequencing. The mutation detected was verified by Sanger. Results: 9 of the 71 family members were diagnosed with HHT with the main manifestation of recurrent nasal bleeding. Genetic analysis showed that the proband and the eldest son of ENG gene exon 9 frameshift mutation: c.1502-1503insGG (p.Gly501GlyfsX18) , and mutations in ACVRL1 and SMAD4 genes were not detected. Conclusion: The frameshift mutation c.1502-1503insGG (p.Gly501GlyfsX18) of the ENG gene is the genetic basis for the pathogenesis of this HHT family.

OBJECTIVETo investigate the tumor suppression efficacy of histone deacetylase inhibitor, phenylbutyrate (PB), in combination with DNA methylation inhibitor 5-Aza-2-deoxycytidine (5-Aza-CdR) in the treatment of Kasumi-1 xenograft tumor in nude mice and its mechanism.

METHODSThe nude mice model of Kasumi-1 xenograft tumor was established by subcutaneous inoculation. Latency of tumor formation, the ability of Kasumi-1 cells pre treated with PB to form the xenograft tumor, and the tumor suppression activity of PB and 5-Aza-CdR by intraperitoneal injection in xenografted mice model were detected. Cell differentiation and cell cycle parameters of the tumor cells were analyzed by flow cytometry analysis, apoptosis by TUNEL in situ hybridization, and tumor microvessel density (MVD) by immunohistochemistry study.

RESULTSThe latency of tumor formation in mice with or without previous lienectomy was 17 approximately 23 and 40 approximately 50 days, respectively. Tumor cells xenografted could not be found in other tissues than in inoculation area, and still harbored the specific t(8;21) and AML1-ETO fusion gene. When the xenografted mice models treated with PB, 5-Aza-CdR, or both, the tumor growth inhibition rates were 49.07%, 25.69% and 87.46% (P < 0.05), the apoptosis indexes (AI) of tumor cells were (2.25 +/- 0.85)%, (1.32 +/- 0.68)%, and (5.41 +/- 1.56)% (P < 0.05), and the microvessel densities (MVD) were 21.69 +/- 6.25, 28.34 +/- 4.24 and 9.48 +/- 3.21 (P < 0.01), respectively. All the data above were significantly different from that in control (P < 0.05). The expression of CD11b and CD13 antigen of the tumor cells was increased in xenografted mice model treated with PB when compared with the control \[(12.08 +/- 1.02)% and (54.91 +/- 2.72)%\], respectively (P < 0.01), and tumor cells showed a cell cycle arrest with increased G(0)/G(1)-phase cells and decreased S-phase cells.

CONCLUSIONPB inhibited the growth of Kasumi-1 xenograft tumor by inducing tumor cell apoptosis and differentiation, and suppressing its angiogenesis in vivo. 5-Aza-CdR could significantly enhance the antitumor activity of PB.
