Neurolymphomatosis(NL) is characterized by lymphomatous infiltration of the peripheral nervous system. We report a case of neurolymphomatosis(NL) which was confirmed by sural nerve biopsy. Sural nerve specimen from a 49-year-old female patient with weakness of limbs was examined with routine histochemical and immunohistochemistry staining, in which the first antibodies against CD3, CD20, CD45, CD45RO and CD68 were used. Numerous T-lymphoma cells invaded in the adipose tissue of epineurium of sural nerve. The nerve biopsy showed marked axonal degeneration of myelinated fibers. The clinical and histopathologic findings confirmed the diagnosis of neurolymphomatosis.

Objective To study the therapeutic effect of intravitreal injection of ranibizumab combined with vitrectomy for the treatment of neovascular glaucoma (NVG). Methods The clinical data of 21 NVG patients who had underwent vitrectomy were retrospectively analyzed. The patients were treated with intravitreal injection of ranibizumab 0.5 mg, then were given the vitrectomy after 3 to 5 d after treatment. The whole retinal photocoagulation was performed during the operation. Cataract surgery was combined in 16 patients, and ciliary photocoagulation was combined in another 15 patients. All patients were followed up for 6 to 12 months, and the intraocular pressure, visual acuity and neovascularization of iris (NVI) were observed. Results The rate of NVI symptoms resolving completely 3 weeks after operation was 80.95％(17/21). The intraocular pressure 1 week, 1 month, 3 months and 6 months after operation was significantly lower than that before operation: (18.6 ± 5.1), (14.3 ± 4.8), (12.8 ± 4.4), (15.1 ± 3.7) mmHg (1 mmHg=0.133 kPa) vs. (42.8 ± 7.3) mmHg, and there was statistical difference (P<0.05). Two months after operation, 2 cases were not able to control by chemicals, and were treated with transscleral cyclophotocoagulation. Six months after operation, the intraocular pressure was completely controlled in 15 cases, and conditionally controlled in 6 cases. No ocular hypotension occurred. The visual acuity was not improved in 4 cases, but the rest were improved in different degrees. Conclusions For the patients of NVG combined with vitreous hemorrhage and obvious proliferation, intravitreal injection of ranibizumab in the first place, and then combined with vitrectomy, whole retinal photocoagulation and ciliary photocoagulation can obtain good effect.

Objective:To determine if suitable electric pulses-mediated DNA and DNA and bupivacaine complexes delivery technologies could enhance effects of botulinum neurotoxin serotype A (BoNT/A) DNA vaccines in mouse model. Methods:Vaccination of mice i.m. with plasmid DNA replicon vaccine pSCARSHc and conventional plasmid DNA vaccine pcDNASHc following electric pulses and with DNA and bupivacaine complexes. AHc-specific group antibody ELISA titers and lymphocyte proliferative responses of mice were detected and IgG1 and IgG2a isotype profiles were assayed. Results:Immune effects of DNA vaccines were enhanced following electric pulses and bupivacaine delivery. Effects of DNA vaccines following electric pulses were better than that of DNA vaccines formulated with bupivacaine,and the combined delivery technology of electric pulses and bupivacaine induced the highest level of specific antibodies and lymphocyte proliferative responses. Plasmid DNA replicon vaccine pSCARSHc induced relatively higher AHc-specific antibodies and lymphocyte proliferative responses in immunized Balb/c mice than conventional plasmid DNA vaccine pcDNASHc in these DNA delivery technologies. And vaccine pSCARSHc induced Th2/Th1-type immune responses with a general bias to Th2-type,and vaccine pcDNASHc induced Th2-type immune responses. Conclusion:Suitable electric pulses-mediated DNA and DNA and bupivacaine complexes delivery technologies could enhance effects of BoNT/A DNA vaccines in mouse model. Therefore,the methods described here potentially provide suitable strategies in developing an efficacious vaccine against botulinum neurotoxin serotype A.

This study is to investigate the sedative and hypnotic effects of a novel compound H1208. The sedative activity of H1208 was investigated by recording the spontaneous locomotor activity of mice. The hypnotic property was evaluated by the latency and duration of sleep (loss of righting reflex) in mice and the effect of hypnotics on sleep pattern of electroencephalogram were studied in conscious, freely moving mice with chronically implanted electrodes. The brain monoamine neurotransmitters levels in mice were measured by high performance liquid chromatography-electrochemical detection. The spontaneous locomotor activity was decreased by 56.7% and 80.2% in H1208 (5 and 25 mg x kg(-1), ip) treated mice, respectively. The loss of righting reflex was directly induced in mice after H1208 (60 mg x kg(-1), ip) administration. The non-rapid eye movement sleep increased significantly by 131% and 259%, respectively, within 3 hours after H1208 (30 and 60 mg x kg(-1), ip) administration. However, the rapid eye movement sleep decreased significantly. The contents of DA in the striatum and cortex and 5-HT in the cortex decreased significantly. These results demonstrated that H1208 has potent sedative and hypnotic effects, which may be closely related to the decreased contents of DA and 5-HT in mouse brain.

Aim To investigate the protective effects of YXETNZ injection on SH-SY5 Y cells damaged by oxygen-glucose deprivation ( OGD ) , and explore its functional mechanisms. Methods After 4 h of OGD, the cells were treated with 25 mg·L-1 drugs for 1 h. Subsequently, cell viabilities were measured by cell counting kit-8 ( CCK-8 kit ) and cell apoptosis was measured by caspase-3/7 assay kit according to manu-facturer’ s instructions. Furthermore, cell death was also detected by ELISA. The levels of phospho-Akt, phospho-PKA,phospho-Bad were evaluated by western blot. Results Oxygen-glucose deprivation significant-ly decreased the cell viabilities of SH-SY5Y cells, while YXETNZ injection significantly increased cell vi-abilities, phospho-Akt, phospho-PKA and phospho-Bad. Furthermore, YXETNZ injection also reduced the activities of caspase-3/7 and cytoplasmic histone-asso-ciated-DNA-fragments contents. Conclusion Our re-searches demonstrat that YXETNZ injection shows good neuroprotective effects on SH-SY5 Y cells after oxygen-glucose deprivation. The underlying mechanisms may be associated with activation of PI3 K/Akt/Bad/caspase-3/7 , cAMP/PKA/Bad/caspase-3/7 signaling pathway.

Objective:To investigate the relationship between dopamine D1 receptor ( DRD1 ) gene polymorphisms and clozapine efficacy in male schizophrenic patients. Methods:Totally 46 male schizophrenic patients were treated by clozapine for 6-8 weeks. The clinical response was determined by the Positive and Negative Symptom Scale (PANSS). DRD1 gene rs265981, rs5326, rs4532, rs1799914, rs686 and rs4867798 polymorphisms were detected by the gene sequencing, while plasma clozapine levels were monitored during the treatment. Results:The total clinical efficacy of clozapine response group and the non-response group was compared, the distribution of rs265981 genotype TT, TC and CC and allele T and C had statistically significant differences (P=0. 025;P=0. 005), and the distribution of rs686 genotype CC, CT and TC and allele C and T had statistically significant differences ( P=0. 044;P=0. 010). The negative symptom of the response group was compared with that of the non-response group, the distribution of rs4532 gen-otype GG, GA and AA and allele G and A had statistically significant differences (P=0. 034; P=0. 013). Conclusion: The poly-morphisms of DRD1 gene rs265981 and rs686 may have influence on the clinical efficacy of clozapine, and rs4532 may have influence on the negative symptom.

Objective　To explore the metabolism of micronutri ents related to dark adaptation of radar operators through nutritional intervent ion. Methods　A total of 34 male radar operators aged between 18 ～29 years old were randomly divided into control and experimental groups. The c ontrol group were on normal diet, and the experimental group received the supple ment of VA, Zn and Se in additional to normal diet. The experiment lasted 4 week s. The levels of serum VA, Zn and Se were measured before and after the experime nt. Results　The levels of serum VA, Zn and Se in the experime ntal group were significantly higher than that in the control group after the experiment (P<0.01). Conclusion　The supplement of VA, Zn an d Se for 4 weeks may elevate, the levels of serum VA, Zn and Se significantly (reached or surpassed normal levels) and suggests that VA, Zn and Se su pplementation may effectively enhance the dark adaptation of radar operators.
