Objective To investigate the effect of mesenchymal stem cells (MSCs) on subcutaneous xenograft tumors in mice with Lewis lung cancer. Methods MSCs isolated from bone marrow of C57BL/6 mice were made into single cell suspension and were cultured in vitro. The cells of the 4th to 5th passage were used for the subsequent experiments. Fifty six C57BL/6 mice were inoculated subcutaneously with Lewis lung cancer cells, and were grouped into Group D0 (MSCs were given simultaneously with inoculation)and Group D10(MSCs were given 10 d after inoculation). Group D0 included three subgroups (n=8): Group 1 with inoculation of tumor cells, Group 2 with inoculation of tumor cells and MSCs, and Group 3 with inoculation of tumor cells and tail intravenous injection of MSCs. Group D10 included four groups: Group 4 with inoculation of tumor cells and injection of MSCs in tumors, Group 5 with equivalent PBS (the control of Group 4), Group 6 with inoculation of tumor cells and tail intravenous injection of MSCs, and Group 7 with equivalent PBS (the control of Group 6). The time of tumor formation and the volume of tumor were observed and compared among the groups. ResultsIn Group D0, earlier onset of tumor development was observed in Group 2 as compared to Group 1 and Group 3 (P<0.05), while there was no significant difference on the volume of tumor in the three groups (P>0.05). In Group D10, the volume of tumors were larger in Group 4 compared to the control (P<0.05), while there was no significant difference on the volume of tumors between Group 6 and the control (P>0.05). Conclusion Inoculating mixture of MSCs and Lewis lung cancer cells accelerates tumor formation,and injection of MSCs in tumors stimulates the growth of tumors.

Placentation,which is critical for maternal-fetal exchange of nutrients and gases,is a complicated process comprising stepwise vasculogenesis and angiogenesis.Hypoxia caused by impairedtrophoblast invasion may cause various angiogenic abnormalities in human placenta.The Notchl signaling pathway plays an important role in the regulation of angiogenesis.The angiogenesis of human umbilical vein endothelial cells (HUVECs) under normal/hypoxic conditions and the mRNA/protein level of Notchl/Dell4/Jaggedl were investigated in this study.The effects of DAPT/JAG-1 on the migration of HUVECs were also assessed by cell wound healing assay,so as to discover the possible role of notchl signaling pathway in the angiogenesis of human placenta.The results showed that angiogenic ability of HUVECs was seriously reduced under hypoxic conditions.The mRNA and protein levels of Notchl/Dell4/Jaggedl were decreased in the hypoxic group compared to the control one.In addition,the migration capability of HUVECs was significantly obstructed when treated with DAPT and under hopoxic condition,but promoted when treated with JAG-1.The above results demonstrate that hypoxia downregulates the angiogenesis in human placenta via Notch 1 signaling pathway.

Objective To investigate the efficacy of no-fire constant temperature moxibustion for cervical spondylosis. Method Sixty outpatients diagnosed with cervical spondylosis were randomized to a treatment group (receiving no-fire constant temperature moxibustion) and a control group (receiving electroacupuncture). Both groups were treated once every other day, 10 days as one course, for two consecutive courses. The symptoms were scored using the Assessment Scale for Cervical Spondylosis in the patients at the enrollment day and after one and two courses of treatment. Result The total efficacy rate was 90.0% in the treatment group and there was a statistically significant difference compared with the control group (P<0.05). Variance analysis of the Assessment Scale for Cervical Spondylosis scores before treatment showed no statistically significant difference between the two groups (F=0.442, P>0.05), indicating comparability. Variance analysis of the Assessment Scale for Cervical Spondylosis scores after one course of treatment still showed no statistically significant difference between the two groups (F=3.674, P=0.06). Variance analysis of the Assessment Scale for Cervical Spondylosis scores after two courses of treatment showed a statistically significant difference between the two groups (F=18.705, P < 0.05). The therapeutic effect of electroacupuncture on cervical spondylosis was better than that of no-fire constant temperature moxibustion. Conclusion No-fire constant temperature moxibustion is convenient to use, safe, effective and highly acceptable to patients. It can be clinically used to treat cervical spondylosis.

Objective To discuss the technique and value of preoperative reformatting with three-dimensional computed tomography technique for C_2 pedicle screw track.Methods GE Light Speed 16 Pro spinal CT scans of 15 adult dry vertebrae were loaded into an imaging station (software ADW4.2).Two methods of C_2 pedicle screw techniques were analyzed through virtual screw trajectory by VR (volume rendering) and MPR (multiple planar reformatting) techniques,in method A,screw entry point was the intersection between the media-vertical and the cranial line of C_2 inferior facet joint,in method B,the screw track was from the cranial and medial quadrant of the dorsal part of C_2 inferior facet joint.Results The screw track could be observed dynamically from any plane.Two vertebrae were ob- served with smaller height in isthmus and the medial edge of the transverse foramen since no space was a- vailable for the screw.The screw trajectories data were compared between method A and method B,which showed that the angles towards the cephalad (in sagittal plane) and midline (in transverse plane) were bigger in method A than in method B (P<0.05,0.01),but the safe screw diameter was smaller in method A than in method B (P<0.05),and there was no difference of the screw length between the two methods(P<0.05 ).Conclusion In this research,the individual C_2 pedicle screw entry points, screw diameter and security screw angle can be simulated,and the screw track can be observed dynami- cally to make sure if it transits the bone structure completely.Preoperative three-dimensional computed tomography reformatting for pedicle screw track is of great value in clinical and basic researches.

OBJECTIVETo observe clinical curative effect of cake-separated moxibustion on impaired glucose regulation (IGR) and explore its action mechanism.
METHODSSixty cases were randomly divided into a simple lifestyle intervention group (control group) and a cake-separated moxibustion combined with lifestyle intervention group (observation group), 30 cases in each one. The control group was treated with lifestyle intervention. Based on lifestyle intervention, cake-separated moxibustion at Pishu (BL 20), Weishu (BL 21) and Yishu (EX-B 3) was applied to the observation group. Fast plasma glucose (FPG), two hours plasma glucose after oral glucose tolerance test (OGTT2hPG), fasting insulin (FINS), homa insulin resistance index (HOMA-IR), blood lipid, body mass index (BMI) and waist circumference (WC) were observed in the two groups before and after treatment.
RESULTSAfter treatment, the OGTT2hPG and FPG were both decreased significantly (both P<0.05) in the two groups, compared between the two groups, the differences of FPG [(0.41 +/- 0.42) mmol/L vs (0.05 +/- 0.08)mmol/L] and OGTT2hPG [(0.85 +/- 0.53)mmol/L vs (0.17 +/- 0.19)mmol/L] were both statistically significant. There were no significant changes in FINS, HOMA-IR, blood lipid, BMI and WC in the control group before and after treatment (all P>0.05), but FINS, HOMA-IR levels, triglycerides (TG), total cholest-erol (TC), low density lipoprotein (LDL-C), BMI and WC in the observation group were decreased obviously after treatment (all P<0.05), which had statistical differences between the two groups (all P<0.05).
CONCLUSIONThe cake-separated moxibustion combined with lifestyle intervention can obviously control blood glucose levels, improve insulin resistance and blood lipid levels, decrease BMI and WC.
