OBJECTIVE:To observe clinical efficacy and safety of naloxone hydrochloride combined with Danshen injection in the treatment of neonatal hypoxic ischemic encephalopathy(HIE). METHODS:104 patients with HIE were randomly divided into observation group and control group with 52 cases in each group. The control group was treated with Naloxone hydrochloride injec-tion 0.02 mg/kg,ivgtt,qd and conventional symptomatic treatment;while observation group was additionally treated with Danshen injection 4-6 ml+10% Glucose injection 20 ml,ivgtt,qd,on the basis of the control group. Treatment course of 2 groups lasted for 7 d. Clinical efficacy,symptom and sign recovery of 2 groups were compared,as well as levels of serum MMP-9,IL-6 and TNF-α,cerebral hemodynamic parameters and ADR. RESULTS:There was no statistical significance in MMP-9,IL-6,TNF-α and cerebral hemodynamic parameters before treatment(P>0.05). The total effective rate of observation group(92.31%)was signifi-cantly higher than that of control group (75.00%);after treatment,the recovery time of consciousness disturbance,primitive re-flex and muscle tension in the observation group were shorter than those in the control group;the levels of serum MMP-9,IL-6 and TNF-α in observation group were significantly lower than those in control group;peak systolic flow velocity(PSFV),end-dia-stolic flow velocity (EDTV) were higher in the observation group than in the control group,with statistical significance (P<0.05);resistance index (RI) was lower than in control group,but without statistical significance (P>0.05). No ADR was ob-served in 2 groups. CONCLUSIONS:Naloxone hydrochloride combined with Danshen injection can significantly promote HIE and signs recovery,reduce the levels of serum MMP-9,IL-6 and TNF-α,and improve hemodynamic parameters with good safety.

To prepare the RNAse-resistant virus particles containing the partial gene fragments of avian influenza virus H5N1 for use as RNA standard and control in RNA virus detection, the genes coding the coat protein and maturase of E.coli bacteriophage MS2 were amplified by PCR and then cloned into prokaryotic expression vector pET32a to construct the intermediate vector pET32a-MS2. In addition, the gene sequences coding hemagglutinin (HA), neuraminidase(NA) and M protein of the H5N1 virus were also cloned separately to the down-stream of plasmid pET32a-MS2, thus constructing the prokaryotic expression vectors pET32a-NS2-HA, pET32a-MS2-NA and pET32a-MS2-M. These recombinant plasmids were then transformed separately to E.coli BL21(DE3) with induction by IPTG. to express the virus-like particles. The virus-like particles observed under electron microscopy were identified by RT-PCR ,while their stability was confirmed by real-time RT-PCR. In this way, the virus-like particles were successively constructed and identified through PCR amplification, enzymolysis identification and sequencing analysis. These virus-like particles observed under electron microscopy appeared to be circular in shape with a diameter of about 50 nm. Their stability was proved to be rather good. From these observations, it is apparent that these virus-like particles can be used as RNA standard and quality control in the detection of avian influenza virus H5N1.

17 strains of bacterium that produced a large amount of ?-PGA when it was grown aerobically in a culture medium containing ammonium salt and sugar as sources of nitrogen and carbon respectively,were isolated from bean products.With the following identifications of colony morphology,physiological and biochemistry experiments,and genetics,the strain PGA-O-7 was classified as a Bacillus subtilis.The PGA production 2.8 (mg/mL) was obtained when it was grown in a medium containing 3% ammonium sulfate and 4% glucose at 30℃ for 72h with sharking.

Objective Prospective comparison was done on concurrent chemo-radiotherapy and se- quential chemo-radiotherapy for unresectable stageⅢnon-small cell lung cancer(NSCLC) and to evaluate three different regimens of concurrent chemo-radiotherapy.Methods Ninety-six such patients were ran- domized into four groups:1.sequential chemo-radiotherapy group received two cycles of induction chemother- apy with 40 mg/m~2 of cisplatin on D 1-3,29-31 and 100 mg/m~2 of etoposide on D 1-3,29-31 before conven- tional radiotherapy,2.concurrent chemo-radiotherapy group 1 received 100 mg/m~2 etoposide on D 1-3 and DDP 40 mg/m~2 on D 1-3,D 29-31,iv.drip,3.concurrent chemo-radiotherapy group 2 received concurrent chemotherapy with 40 mg/m~2 of paclitaxel every Monday during conventional radiotherapy,4.concurrent chemo-radiotherapy group 3 received concurrent chemotherapy with 40 mg/m~2 of paclitaxel every Monday during three-dimensional conformal radiotherapy.All patients were irradiated with 2.0 Gy/fraction,5 frac- tions/week,to a total dose of 60-64 Gy.They all received two cycles of consolidation themotherapy with 40 mg/m~2 of cisplatin on D 1-3 and 100 mg/m~2 of etoposide on D 1-3.Results The overa/1 response rate was 67%,71%,71% and 79% for sequential ehemo-radiotherapy group,concurrent chemo-radiotherapy group 1,2 and 3,respectively.There was a significant difference between the concurrent chemo-radiotherapy and sequential chemo-radiotherapy(P＜0.05).The 1-,3-and 5-year overall survival rate(OS) was 54%,8% and 4%;71%,17% and 8%;79%,17% and 8%;83%,46% and 13%,respectively for the four groups. The difference among all these groups(P=0.017) was significant.It was also significant between the con- current chemo-radiotherapy group 1 and 3 (P=0.046).The difference of distant metastasis rate among all the groups was statistically insignificant (P＞0.05) also was the difference of toxicity (P＞0.05),but the severe toxicity of concurrent chemo-radiotherapy groups 1 and 2 were higher than the sequential chemo-radio- therapy group and concurrent chemo-radiotherapy group 3.Conclusions Better locoregional progression- free survival and overall survival of unresectable stageⅢnon-small cell lung cancer could be achieved by concurrent chemo-radiotherapy as compared with sequential chemo-radiotherapy though at the expense of in- crease in toxicity.With the combination of concurrent chemo-radiotherapy and conforrnal radiotherapy,the o- verall survival rate could be much improved with miider toxicity.

OBJECTIVETo observe therapeutic effects of different needle-retained durations at scalp acupoints on Tourette syndrome (TS).

METHODSSixty-two cases of TS were randomly divided into an observation group and a control group, 31 cases in each group. In the observation group, the needles were retained for 2 h and in the control group, they were retained for 30 min. The middle line of forehead, middle line of vertex and lateral line 1 of vertex were selected as main acupoints, and anterior oblique line of vertex-temporal and posterior temporal line were selected as adjuvant acupoints. They were treated for 2 months, once other day. Yale Global Tic Severity Scale (YGTSS) and Tourette Syndrome Global Scale (TSGS) were used for assessment of therapeutic effects and their therapeutic effects were compared.

RESULTSAfter treatment, YGTSS and TSGS scores had very significant changes in the two groups as compared with those before treatment (both P < 0.01), indicating an obvious improvement in kinetic Tic and vocalizing Tic. The total effective rate was 61.3% in the observation group and 67.7% in the control group with no significant difference between the two groups (P > 0.05).

CONCLUSIONScalp acupuncture therapy of both 2 h and 0.5 h retaining needle can significantly improve symptoms of TS patients, with a similar therapeutic effect.

AIM To explore the effects of Zishui Qinggan Decoction on the mouse model of depression induced by chronic restraint stress(CRS)via ERK/GSK3β/CREB/BDNF signaling pathway.METHODS Except for those of the blank group,the mice of other groups were induced into depression models by CRS,and divided into the model group,the fluoxetine hydrochloride group(10 mg/kg)and the low,medium and high dose Zishui Qinggan Decoction groups(8.835,17.670 and 35.340 g/kg)for the corresponding drug intervention and simultanous CRS treatment.The mice had their sugar water preference experiment and behavior experiment on the 7th and 14th day after administration;the observation of the hippocampal morphological changes by HE staining,the detection of the superoxide dismutase(SOD)activity and malondialdehyde(MDA)level in serum by kits,the detection of levels of serum 5-hydroxytryptamine(5-HT),tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)by ELISA,the detection of the hippocampal mRNA expressions of BDNF,TNF-α and IL-1β by RT-qPCR method,and the detection of the hippocampal protein expressions of ERK1/2,p-ERK1/2,GSK3β,p-GSK3β,CREB and BDNF by Western blot method 14 days after administration.RESULTS Compared with the model group,after 14 days of administration,both fluoxetine hydrochloride group and medium-dose Zishui Qinggan Decoction group displayed increased preference rate of sugar water(P<0.01),shortened immobility time of tail suspension and forced swimming(P<0.01),improved hippocampal damage of nerve cells,decreased levels of serum MDA,TNF-α and IL-1β(P<0.05,P<0.01),increased SOD activity and 5-HT level(P<0.05,P<0.01),decreased hippocampal mRNA expressions of TNF-α and IL-1β(P<0.01),and decreased expressions of BDNF mRNA and p-ERK1/2,p-GSK3β,CREB and BDNF proteins(P<0.05,P<0.01).CONCLUSION Zishui Qinggan Decoction can improve the depression-like behaviors in mice exposed to CRS,and its mechanism may be related to the regulation of hippocampal ERK/GSK3β/CREB/BDNF signaling pathway.

OBJECTIVETo investigate the effects of carnitine on human sperm motility and its potential role in the treatment of male infertility diseases.

METHODSWe obtained sperm by testis puncture from obstructive azoospermia patients and cultured them in vitro with normal culture solution (the control group) and the solution with L-carnitine at the concentration of 100 and 250 mmol/L, respectively. We observed the changes in sperm motility and morphology before and after the treatment, detected the expressions of the germ-specific genes, Vasa, Dazl, Acr, Prm1 and ATPase 6.0 by RT-PCR, and investigated the relationship between L-carnitine and the genes associated with sperm development and maturation.

RESULTSAfter 24 -72 hours of treatment, the percentage of motile sperm was significantly higher in the 100 mmol/L L-carnitine group than in the control and 250 mmol/L L-carnitine groups (P < 0.01); the number of forward moving sperm was obviously increased and sperm morphology remained normal in the 100 mmol/L L-carnitine group. RT-PCR showed that L-carnitine increased the expressions of Acr, Prm1, Dazl and ATPase 6. 0 at the concentration of 100 mmol/L, and decreased the expressions of Dazl, Acr and Prm1 at 250 mmol/L.

CONCLUSIONL-carnitine at a proper concentration may improve the motility of incubated testicular sperm by upregulating the expressions of some sperm-specific genes, which helps sperm selection for intracytoplasmic sperm injection. However, a higher concentration of L-carnitine may reduce the expressions of these genes, probably due to its increased toxicity.

OBJECTIVETo study the clinicopathologic features, immunohistochemical findings, differential diagnosis and prognosis of type II enteropathy-associated T-cell lymphoma (EATL).

METHODSFourteen cases of type II EATL encountered in Department of Pathology, Nanjing General Hospital were retrospectively reviewed. The clinical data, histologic features, immunohistochemical findings and follow-up information were analyzed, with literature review.

RESULTSThere were altogether 12 males and 2 females. The median age of patient was 49 years. The sites of involvement included jejunum (10 cases) and ileum/colon (4 cases). The patients often presented with an abdominal mass, abdominal pain, diarrhea and constitutional symptoms such as fever, night sweating and cachexia. There was no clinical evidence of gluten-sensitive enteropathy. Histologically, the lymphoma cells showed full-thickness infiltration of the intestinal wall. They contained round hyperchromatic nuclei and pale cytoplasm. The stroma was minimally inflamed, with or without associated coagulative necrosis. A remarkable finding was the presence of villous atrophy, cryptal hyperplasia and intraepithelial lymphocytosis. Immunohistochemical study showed that the tumor cells expressed CD3, CD43 and CD8 (14/14). Some of them were also positive for CD56 (11/14) and CD30 (2/14). The staining for CD4, CD20, CD79a and myeloperoxidase was negative. A high proliferation index was demonstrated by Ki-67 immunostain. In-situ hybridization for EBER was negative. Follow-up data were available in 9 cases. The duration of follow-up ranged from 6 months to 36 months. Seven patients died within 14 months.

CONCLUSIONSEATL is a rare type of lymphoma with intestinal involvement. Associated enteropathy is not demonstrated, in contrast to cases encountered in Nordic countries. A correct diagnosis requires evaluation of clinical manifestations, pathologic features and ancillary study results.
