Objective To investigate the inhibitive effects of Ad-PUMA combined with temozolomide on human glioblastoma cells growth in vivo experiments. Methods The nude mouse model with human glioblastoma cells subcutaneous transplantation was established. The mice were randomly divided into 4 groups to receive subcutaneous injection at the 14th day separately with: Normal saline 100 μl (control, n=8), Ad-PUMA 2×108 pfu/100 μl (PUMA group, n=8), 10 mg/kg TMZ (TMZ group, n=8) and 2×108 pfu/100 μl Ad-PUMA + 10 mg/kg TMZ (combined group, n=8). Mice were killed after 20 days treatment.Tumor volume, inhibition rates and apoptotic index (AI) were measured, meanwhile, apoptotic tumor cells were detected by TUNEL technology respectively. The expression of MGMT mRNA and MGMT protein were revealed by the methods of RT-PCR and Western blot. Results According to the order: control group, AdPUMA group, TMZ group, combined group, tumor volumes were (3.68±0.09), (2.63±0.13), (2.13±0.07),(0.97±0.02) cm3 respectively (P<0.05); the inhibitive rates were 0, 28.5 %, 42.1%, 73.6 % respectively and AI were (2.0±1.2) %, (11.4±2.6) %, (7.6±3.2) %, (20.6±8.6) % (P<0.05). The results of Western blot and RT-PCR showed that MGMT mRNA and MGMT protein levels in TMZ group were higher than other groups (all P<0.01). Conclusion Ad-PUMA combined with TMZ greatly enhances the sensitivity of human glioblastoma cells to TMZ and could effectively inhibit the proliferation and promote the apeptosis of glioblastoma cells, its mechanism was probably related Ad-PUMA promote apoptosis and inhibit MGMT expression.

Objective To analyze the serious complications of transurethral resection of the prostate (TURP).Methods A retrospective study was conducted to summarize the clinical data of 1950 patients with benign prostatic hyperplasia from January 2005 to December 2014.All patients received TURP.The mean patient Age,disease course,IPSS score,PV and Qmax of 1 950 eligible patients were 71 years (54 to 87 years),7.6 years(0.5 to 15.0 years),(65.1 ±33.4)ml,25.5 ±3.9 and (8.1 ±2.6)ml/s,respectively.Intraoperative and postoperative complications were graded according to the CLASSIC and modified Clavien classifications,respectively.Serious complications were defined as grade Ⅲ or higher.Results Among the TURP procedures,99 serious complications occurred,resulting in a serious complication rate of 5.1%,Serious intraoperative and postoperative complication rates were 1.2% (24 cases) and 3.9% (75 cases),respectively.Serious intraoperative complications included ureteral orifice injury (3 cases),bladder explosion (4 cases),and transurethral resection syndrome (17 cases).Serious postoperative complications included massive hemorrhage (26 cases),severe dysuria (18 cases),permanent urinary incontinence (4 cases),cardio-cerebral vascular accident (5 cases),pulmonary thrombosis (3 cases),severe infection(18 cases),and death (1 case).Conclusions Serious complications may occur at any stages during TURP.Understanding the causes and characteristics of complications,strengthening the prevention and effective treatment is the key measure to reduce the incidence rates.

Hereditary spastic paraplegia is a heterogeneous group of genetic neurodegenerative disorders of the
nervous system. It is classified into four subtypes based on the mode of inheritance; and among them,
most autosomal recessive hereditary spastic paraplegia cases are due to type SPG11 and SPG15 gene
mutations. Autosomal recessive hereditary spastic paraplegia cases with SPG30 gene mutation have
never been reported in China. Herein, we present our experience with a case of hereditary spastic
paraplegia with SPG30 gene mutation in our hospital from North East China. In this patient we detected
a missense mutation of c.499 C>T (p.Arg167Cys) in gene KIF1A, a causative gene of type SPG30.

Toxoplasmosis is a worldwide zoonosis caused by an intracellular protozoan parasite, Toxoplasma
gondii. We report here a diabetic patient who was diagnosed as toxoplasmosis with multiple cranial
nerve palsies and cavernous sinusitis. A 37-year-old male presented with an 11-day history of gingival
pain, one day history of ptosis and diplopia. He has been having diabetes mellitus for 6 years, and has
a history of contact with cats. After admission, his symptoms worsened with right 3rd to 7th cranial
nerve palsies. The brain magnetic resonance imaging (MRI) showed cavernous sinusitis in the right
sellar region. Serology for toxoplasma was positive for IgM and negative IgG. The patient was treated
with oral clindamycin (900 mg/day) and dexamethasone (15 mg/day). The right visual acuity and
lid-conjunctival swelling improved after 3 days. At follow-up after a month, the movement of the
right eye significantly improved. This case demonstrate the rare occurrence of multiple cranial nerve
(3rd to 7th) palsies from toxoplasmosis cavernous sinusitis, which is a potentially treatable condition.
