OBJECTIVETo explore the clinical effects of Mobi-C cervical artificial disc replacement (CADR) and anterior cervical decompression and fusion (ACDF) in treating single cervical disc herniation.

METHODSFrom June 2009 to June 2012, the clinical data of 27 patients with single cervical disc herniation were retrospectively analyzed. There were 18 males and 9 females, aged from 30 to 62 years old with an average of 46.7 years. Of them, 12 patients were treated with CADR (CADR group) and 15 patients with ACDF (ACDF group). All patients had pain and numbness in neck, shoulder and upper limbs, and courses of disease was from 1 to 13 months with an average of 2.4 months. The data of clinical evaluation and questionnaire survey about quality of life were collected before operation, postoperative at 1 week and final follow-up. Odom criterion was used to evaluate postoperative effect. Visual analogue scale (VAS) was used to record pain levels. Neck disability index (NDI) and health questionnaire SF-36 were used to assess the quality of life.

RESULTSNo complications about nerve and blood vessel were found and the patients were followed up from 6 to 30 months, with an average of 16 months. One week after operation, 10 cases got excellent results and 2 good in CADR group; 5 cases got excellent results and 10 good in ACDF group; there was significant difference between two groups (P<0.05). At final follow-up, 10 cases got excellent results and 2 good in CADR group; 12 cases got excellent results and 3 good in ACDF group; there was no significant difference between two groups (P> 0.05). Pain of upper limbs had obviously relieved between two groups at 1 week after operation and final follow-up (P<0.05). VAS of neck and NDI in CADR group had decreased respectively from preoperative 3.58±0.79, 23.42±6.36 to 0.58±0.51, 5.42±1.68 at 1 week after operation (P<0.05); but the index in ACDF group was no obvious at 1 week after operation. At final follow-up, VAS of neck and NDI and SF-36 score were obviously improved than preoperation (P<0.05) between two groups.

CONCLUSIONMobi-C CADR retains the movement unit in the decompression segment and can quickly recover normal action for patients. Using CADR method has a good curative effect in the early phase, and the clinical effect is reliable, may improve the quality of life.

AIM: To construct prokaryotic expression vector of His-tagged human IP-10 for further study of its biological function in the inflammatory response. METHODS: The coding sequence of IP-10 lacking signal peptide was amplified from human lung cDNA library by polymerase chain reaction (PCR) and the fragment was cloned into pET-14b plasmid for the construction of His-tagged fusion protein expressing vector, pET-14b/IP-10. After being identified by enzyme digestion and sequencing, the recombinant vector was transformed into a strain of E. coli, BL21 (DE_3). The expression of His-tagged fusion protein was induced with IPTG and purified with Ni+-NTA affinity chromatography. Then the chemotactic activity of IP-10 was determined by transwell migration assay on THP-1 cells. RESULTS: The construction of pET-14b/IP-10 recombinant vector was proved by enzyme digestion and sequencing. The fusion protein IP-10, which was purified by a routine Ni+ affinity method, had an activity on the induction of cell migration of THP-1. CONCLUSION: We successfully construct IP-10 fusion protein expressing vector and get the fusion protein with high bioactivity, which provides essential materials for the future studies on IP-10.

Objective To investigate the regulating effects of Zuogui Jiangtang Jieyu Formula (ZJJF) on Bcl-2, Bax and Caspase-8 in hippocampus neuron damage in diabetes mellitus with depression (DD). Methods Hippocampal neurons from 18 d pregnant rats were primitively cultivated, and then combination of glucose and corticosterone was used to construct DD simulation environment. Cultivated hippocampal neurons were randomly divided into normal group, blank serum group, model group, positive medicine (metformin+fluoxetine) serum group and to-be-tested medicine (ZJJF) serum group. Normal group and model group were given same amount culture medium, while other group were given relevant amont of 10％ medicine serum or blank serum. After modeling intervention for 18 h,Hoechst staining was used to detect the apoptosis of hippocampal neurons. The expression of Bcl-2, Bax and Caspase-8 was detected by high content analysis. Results Compared with the control group, hippocampal neuron dendrites ruptured or decreased, neural network connection decreased, cells showed significant staining, broken, uneven distribution of light spots, the expression of Bcl-2 protein decreased significantly (P<0.05), but Bax and Caspase-8 were increased (P<0.05, P<0.01). Compared with the model group, hippocampal neurons in both positive medicine serum group and ZJJF serum group gradually recovered. Hoechst staining showed that the nuclei were significantly homogenized, local highlights were significantly reduced, Bcl-2 protein expression levels were significantly increased (P<0.05, P<0.01), while Bax and Caspase-8 were obviously down-regulated (P<0.05, P<0.01). Conclusion ZJJF has protective effects on hippocampal neurons in DD of model rats, and its mechanism is related to regulating the expression of Bcl-2, Bax and Caspase-8 in hippocampus neuron.

Objective:To investigate the protective effect of lactoferrin(Lf) on lung injury in mice exposed to irradiation.Methods:C57BL/6 J mice were randomly divided into control group, 15 Gy irradiation group (IR group) and lactoferrin combined 15 Gy irradiation group (Lf+ IR group), with 5 mice in each group. The mice in the Lf+ 15 Gy group drank lactoferrin solution (10 mg/ml) from 3 days before irradiation and contained the whole experiments. Then, single chest 15 Gyirradiation was performed both in the IR and Lf+ IR groups. The body weight and other characteristics were monitored during the experiment. The mice were killed at day 14 after irradiation. The lung histopathology was observed by HE staining. Serum inflammatory cytokine such as HMGB1, TNF-α, IL-1β and IL-6 was determined by ELISA method . The expression of inflammatory related protein in lung tissue including HMGB1, TLR4, MyD88 and NF-κB were performed by immune histochemistry and Western blot method.Results:Compared with the control group, lung weight was significantly increased ( t=3.20, P<0.05), pulmonary hyperemia and inflammatory cell infiltration was observed in the IR group. Exposure also significantly increased serum level of TNF-α[(291.80±5.49) vs.(332.25±22.18)pg/ml]( t=3.07, P<0.05), up-regulated the expression of inflammatory related protein in lung tissue ( t=4.04, 4.78, 3.77, 6.14, P<0.05). Lactoferrin intervention (Lf+ IR group) significantly decreased lung weight ( t=2.18, P<0.05), alleviated histopathologic changes, decrease serum levels of HMGB1, TNF-α and IL-1β ( t=4.67, 2.97, 3.49, P<0.05). On the other hand, lactoferrin intervention decreased the positive cell number of HMGB1 and NF-κB, and down-regulated the protein expression of HMGB1, TLR4, MyD88 and NF-κB in lung tissues, with significant difference with the IR group ( t=8.06, 9.80, 3.07, 5.56, P<0.05). Conclusions:Lactoferrin plays the protective effect of radiation-induced lung injury through the downregulation of inflammatory response, such as HMGB1/TLR4/MyD88/NF-κB signaling pathway.

OBJECTIVETo compare the therapeutic effects between the Hwato neuro and muscle stimulator (SXDZ-100) and the regular electronic stimulator (SDZ-II) on chronic functional constipation.

METHODSSixty-four cases of chronic functional constipation were randomly divided into a (SXDZ-100) observation group (n = 33) and SDZ-II control group (n = 31). For the SXDZ-100 group, under the considerations of patients' endurance, Zhigou(TE 6) and Tianshu (ST 25), Zusanli (ST 36) and Shangjuxu (ST 37) were punctured and then the courle of acupoints on the same side were connected with SXDZ-100 apparatus in reinforcing and reducing by twirling and rotating manipulation wave for 30 min, while in the control group SDZ-II apparatus was applied in the same way mentioned above with disperse-dense wave at frequency of 1Hz/20Hz for 30 min. By means of clinical therapeutic effect evaluation and clinical symptom score, the contrast between two groups can be made.

RESULTSAlthough the total effective rates were both 100.0%, the rate of short term effects in SXDZ-100 group (54.6%, 18/33) is significantly higher than that in SDZ-II group (29.0%, 9/31) (P < 0.05). After the treatment, the clinical symptom scores in both groups decreased significantly (both P < 0.05). And the therapeutic effective indices of the SXDZ-100 group were significantly higher than those of the SDZ- II group (P < 0.05).

CONCLUSIONThe therapeutic effect of Hwato neuro and muscle stimulator (SXDZ-100) on chronic functional constipation is superior to that of a regular electronic stimulator (SDZ-II).
