BACKGROUND: It is indistinct that whether ketamine can exert antinociceptive effect througb influencing the transmission of nocuous information in spinal cord; Nitric oxide (NO) in spinal cord participates mainly in the formation and development of hyperalgesia, and it can also induce Fos protein expression. It is still controversal whether it contributes to the transmission and mediation of ketamine to pain signal.OBJECTIVE: To observe the response to formalin stimulation in spinal cord of the rats and the effect of ketamine.DESIGN: Balanced randomized animal trial.SETTING: Department of Anesthesiology, Affiliated Hospital of Xuzhou Medical College; Jiangsu Provincial Key Laboratory of Anesthesiology.MATERIALS: This trial was carried out in the Jiangsu Provincial Key Laboratory of Anesthesiology, Xuzhou Medical College from January to March 2000. Totally 30 Sprague-Dawley rats were chosen and balanced randomized into 6 groups: formalin group (n=6), formalin + ketamine group (n=6), ketamine +formalin group (n=6), ketamine group (n=6), formalin+normal saline group (n=3) and normal saline group (n=3). The gender ratio was the same in each group.METHODS: Formalin group:The rats were stimulated for one hour by subcutaneous injection of 0.05 volume fraction of 200 μL in the center of palm of unilateral fore-claw. Formalin +ketamine group: The rats were stimulated for 10 minutes by formalin, then for one hour by intraperitoneal injection of 100 rg/kg ketamine. Ketamine + formalin group: The rats were injected with ketamine for 10 minutes, then with formalin for one hour. Ketamine group: the same dosage of ketamine was intraperitoneally injected into the rats for one hour. Formalin + normal saline group: The rats were stimulated for 10 minutes by formalin, then intraperitoneally given 10 mL/kg normal saline for one hour. Normal saline group: the same volume of normal saline was intraperitoneally injected into the rats for one hour.MAIN OUTCOME MEASURES: ① Behavioral performance of the rats in each group. ② Spinal sections were chosen, and stained with c-fos genetic immunohistochemical and NADPH-d histochemical methods. The changes of the number of Fos-like immuno-positive neurons (FLI) and FLI/nitric oxide synthase (NOS) double-labeled neurons in the 4-layer sections (layer Ⅰ -Ⅱ ,layer Ⅲ-Ⅳ ,layerⅤ-Ⅵ ,layer Ⅶ-X )of spinal dorsal horn of the rats were observed.RESULTS: All the thirty rats entered the stage of result analysis. ① Behavioral changes: The rats of formalin group and formalin+ normal salinegroup had apparent pain response; Several minutes after injection with ketamine, righting reflex disappeared and did not recover at perfusion period.Prolonged sleep was found without obvious pain response performance. ② FLI neuron expression: A lot of FLI positive neurons were found in the spinal dorsal horn of injec tion side of the rats in the formalin group and formalin+ normal saline group, and they distributed principally in the layer Ⅰ - Ⅱ of spinal dorsal horn.The distribution in the ketamine + formalin group and formalin + ketamine group was basically similar to that in the formalin group and formalin + normal saline group, but positive neuron counts were significantly reduced (P ＜ 0.01). ③ The expression of FLI/NOS double-labeled neurons: The number of double-labeled neurons in the spinal dorsal horn layer Ⅰ - Ⅱ of the rats in the ketamine+ formalin group and formalin+ ketamine group were significantly less than that in the formalin group and formalin+normal saline group [(1±1), (1±1), (7±3), (8±3),P ＜ 0.01].CONCLUSION: Some neurons of ipsilateral corresponding spinal segments participate in the transmission and mediation of pain signal. Ketamine can suppress the activities of these neurons and exert antinociceptive effect. The antinococeptive function of ketamine may be caused by the activity depression of the NOS-positive neurons in spinal cord.

Objective To evaluate serum organochlorine pesticides and residues levels in breast cancer pa-tients between the seriously and lightly earthquake-striken areas of Tangshan. Methods 93 patients of breast cancer from seriously earthquake-striken areas and 65 patients from lightly earthquake-striken areas were selected as study subjects,which serum organochlorine pesticides (DDTs and HCHs) levels were detected and compared with gas chromatography/electron capture. Results Serum organochlorine pesticides and residues levels in 158 patients be-tween the seriously and lightly earthquake-striken areas of Tangshan were not normal distributed. The order of detec-tion rate of HCH isomer in breast cancer patients between the seriously and lightly earthquake-striken areas were β-HCH>δ-HCH >α-HCH >γ-HCH. The orders of detection rate of DDT isomer in breast cancer patients between two areas of Tangshan were PP'-DDE > PP'-DDT > OP'-DDT > PP'-DDD. The serum levels of α-HCH,β-HCH, PP'-DDE and PP'-DDD in breast cancer patients between the seriously and lightly earthquake-striken areas were statistically different. Conclusion The levels of organechlorine pesticides and residues in serum with high detection rate in seri-ously earthquake-striken area are higher than that in lightly earthquake-striken area. It is likely that there is an asso-ciation with a large number of organechlorine pesticides sprayed.

With the development of functional genomics, high throughput analysis of genes’ function has been the mainstream of research, and exogenous gene's over expression via Agrobacterium-mediated transformation is the most commonly used method in gene functional analysis.The versatile plant expression vector cassette named pBHT-5 was constructed by the method of site-specific mutagenesis based on pBI121. First of all, the restriction enzyme SfiI recognition site in trfA gene (X00713) which was relevant to plasmid replication and stability was replaced without changing its amino acid composition. And then the SfiIA,SfiIB sites were added between promoter CaMV35s and terminator NOS. The versatile plant expression vector cassette can be directly used to construct plant expression vector containing the full-length genes cloned by Clontech SMARTTM technology, which will raise the efficiency of vector construction. The result will provide basis of new genes’ high throughput screening and functional analysis, then get the new genes functioning in plant osmotic stress resistance.

Objective:To observe the clinical effect of mild moxibustion for knee osteoarthritis (KOA) and to explore the role of mild moxibustion in relieving pain,reducing stiffness and improving joint dysfunction in patients with KOA.Methods:Eighty patients with KOA were randomly allocated into either a moxibustion group or a medication group by the random number table,with 40 cases in each group.The moxibustion group used mild moxibustion at Neixiyan (EX-LE 5),Dubi (ST 35),Xuehai (SP 10) and Liangqiu (ST 34),30 min each time,3 times a week;the medication group was given celecoxib capsule (celebrex),0.2 g each time,once a day.Both groups were treated for 4 weeks.The visual analog scale (VAS) and Western Ontario and McMaster Universities osteoarthritis index (WOMAC)scores were evaluated before and after treatment.The efficacy of the two groups was compared after treatment.Results:After treatment,the overall efficacy of the moxibustion group was significantly different from that of the medication group (P＜0.05).The VAS and WOMAC scores of the two groups were lower than those before treatment (both P＜0.01).The changes in the VAS and WOMAC scores after treatment in the moxibustion group were significantly different from those in the medication group (both P＜0.05).After treatment,in single item of WOMAC,the changes in pain and joint dysfunction in the moxibustion group were more statistically significant than those in the medication group (both P＜0.05).Conclusion:Mild moxibustion and oral celebrex can reduce the VAS and WOMAC scores of patients with KOA.Mild moxibustion is superior to oral celebrex in relieving pain and improving joint function.

After brief introduction of FISH (fluorescence in situ hybridization),it was discussed of the FISH's application status in research on biological nitrogen removal in recent years. Base on the FISH technology,Characterization of the community in biological reactor could be showed exactly,but more research should be carried out for the study on the effluence on microbial community composition,which was caused by changing operating parameter of biological reactors on the microbial community composition,such as SRT,DO and C/N ratio.The combination of FISH and other methods such as PCR-DGGE and 16S rRNA/rDNA will led to the identification of the microbial community which response for the nitrogen-removal in wastewater treatment plant.

Conclusion Rehabilitation stroke unit has preferable effect on shoulder-hand syndrome after stroke.

OBJECTIVETo investigate the dynamic expression and role of SENP1 (SUMO-specific proteases-1) in the pulmonary vascular wall of rat during the development of hypoxic pulmonary hypertension (HPH).

METHODSForty adult male Wistar rats were randomly divided into 5 groups (n = 8), and exposed to normoxia (Control group) or exposed to hypoxia for 3, 7, 14 or 21 d, respectively. The HPH models were established by normobaric intermittent hypoxia. Mean pulmonary arterial pressure (mPAP), right ventricle hypertrophy index (RVHI), and vessel morphometry were measured. Reverse transcriptase-polymerase chain reaction(RT-PCR) and in situ hybridization were used to determine the mRNA expression of SENP1. Immunohistochemistry and Western blot were used to determine the protein expression of SENP1.

RESULTSThe hypoxic rats developed pulmonary vascular remodeling in pulmonary arterioles after 7 d of hypoxia exposure. Pulmonary vascular remodeling in pulmonary arterioles significantly increased after 14 d of hypoxia. The level of mPAP in hypoxic rats increased significantly after 7 d of hypoxia, reached its peak after 14 d of hypoxic exposure. RVHI was markedly increased after 14 d of hypoxia. In situ hybridization and immunohistochemical analysis showed that SENP1 mRNA and protein were positively stained in control. SENP1 mRNA expression had little changes after exposure to hypoxia compared with the control, however, SENP1 protein expression was declined gradually after 7 d of hypoxia. The results of RT-PCR and Western blot showed that the same dynamic expression of SENP1 mRNA and protein in lung tissues of rats. Linear correlation analysis showed that SENP1 protein were negatively correlated with mPAP, pulmonary vascular remodeling index and RVHI.

CONCLUSIONUnder chronic hypoxia, SENP1 protein can be degradated. The dynamic expression of SENP1 protein may play a role in implicating in the development of HPH.
