BACKGROUND: In vitro culture condition and culture efficiency are different in reported umbilical cord-derived mesenchymal stem cells, and lacked of unified standards. Different derived mesenchymal stem cells have different biological properties. Therefore, it is very necessary to establish a simple and high-performance culture system for umbilical cord-derived mesenchymal stem cells. OBJECTIVE: To observe the growth state of human umbilical cord-derived mesenchymal stem cells in different culture systems in vitro and adenovirus infection efficiency. METHODS: Mesenchymal stem cells were separated from healthy full-termed delivery fetus using collagenase digestion method and purified by adherent culture. These cells were cultured and amplified in DMEM (low glucose), MesenPRO RS~(TM) Medium and STEMPRO~(R) MSC SFM in vitro. The 3-5 passage mesenchymal stem cells were infected by the Ad5-EGFP, Ad5/11-EGFP, Ad5/35-EGFP as multiplicity of infection (MOI)=1, 10, 100. Viral infection and green fluorescence expression were observed at post-infection 24, 56 and 72 hours using inverted fluorescence microscope. RESULTS AND CONCLUSION: The cell morphology in STEMPR~(R) MSC SFM was different from other two culture system and these cells were not easy to adherent after trypsin digestion. Cell doubling time in the MesenPRO RS~(TM) Medium was shorter than other two groups. Mesenchymal stem cells were infected by Ad5/35-EGFP with higher efficiency than other two kinds of adenovirus, but part of cells appeared apoptosis. The infection efficiency of Ad5/11-EGFP was highest. The fluorescence intensity was gradually increased with increased MOI.

The main physiological role of iodine in the body is to synthesize thyroid hormone. Both iodine deficiency and iodine excess can lead to severe thyroid diseases. While its role in thyroid diseases has increasingly been recognized, few relevant platforms and techniques for iodine detection have been available in China. This paper summarizes the advantages and disadvantages of currently iodine detection methods including direct titration, arsenic cerium catalytic spectrophotometry, chromatography with pulsed amperometry, colorimetry based on automatic biochemistry, inductively coupled plasma mass spectrometry, so as to optimize the iodine nutrition for patients with thyroid diseases.

Objective To analyze negative lymph nodes of 34 non-small cell lung cancer(NCLC) patients with total correction by means of fluorescent quantitation PCR and immunohistcchemistry,and to form molecular bi- ology staging.Methods Clinical data and tissue samples of 193 lymph nodes were collected from 34 patients under- going resection for non-small cell lung cancer.Using fluorescent quantitation reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry method,lymph nodes were examined for CEA gene mRNA,P53 and CK to form molecular biology staging.All the patients were followed-up for an average of forty months.Results The CEAmRNA was identified in 21.7% (42/193) lymph nodes negative patients from 17 patients(17/34,50%); TMN staging was up-regulated in 8 patients;positive lymph nodes were increased in 9 patients.P53 and AE1/AE3 were identified 9.8%(19/193) from 11 patients,18.6 % (36/193)from 15 patients,separately;TMN staging was up-regulated in 2 patients of P53 examination and 5 patients of AE1/AE3 analysis;positive lymph nodes were in- creased in in 7 patients of P53 examination and 11 patients of AE1/AE3 analysis.There was obvious statistical sig- nificance in them,but the molecular biology staging based on the three markers was not an independent factor on re- currence and metasis of lung cancer.Conclusion CEAmRNA.P53 and AE1/AE3 analysis could find lung cancer micrometasis more sensitively to form molecular biology staging which was relative to the prognosis,but not an inde- pendent prognostic indicator.It might be good to the therapy strategy after operation.

OBJECTIVETo investigates the mechanism of hypooglycemic effect of conduritol A of stems of Gymnema sylvestre.

METHODFourteen days later after administration, observation is taken on the change of these mice and rats weight, the FBG, TG, CHO, SOD, MDA, INS, TNF in serum were also detected with enzymology method and Radioimmuoassay method. Take the liver to determine the disposal of glucose. Take the pancreas to do the HE and immunohistochemistrial staining, and show pancreas islet beta-cell. Calulate thymus, pancreas, splenica index.

RESULTCompared with diabetic model mice, high and middosage of conduritol A could remarkably reduce fasted blood sugar in diabetic rats induced by alloxan (P < 0.01). Significantly increase the level of serum insulin (P < 0.05). Activity of SOD was obviously increased, and amount of MDA was obviously decreased (P < 0.05). The amount of conduritol A disposal of glucose was obviously increased (P < 0.05). Significantly increase thymus, pancreas, splencia index (P < 0.01 or 0.05); inhibited the atrophy of thymus, pancreas, splencias of the diabetic rats induced by alloxan. Compared with diabetic model group, cell structure and form of conduritol A had been some way improved. The immunohistochemistry results showed that beta-cells numbers of pancreas in each conduritol A group were more than those in the model group.

CONCLUSIONConduritol A could have an effect on regulating the metabolism of blood lipid, free-radical scavenging, enhancing the antioxidant ability, potentiating immune function. Promoting synthesis of hepatic to decrease fasted blood suger.

OBJECTIVETo probe the recovery mechanism of Zhenggu powder (ZGP) on acute soft tissue injury in cell levels.

METHODSForty rabbits which established animal model of acute soft tissue injury with hammer hitting,were divided randomly into normal group (A), model group (B), vaseline group (C)and ZGP group (D). Injured part was applied external drug daily after model was made. All animals were killed after using drug for 4 days. The local tissue of injured part was taken pathologic study, and was measured the content of IL-1beta, IL-6, TNFalpha by ELISA method and TXB2, 6-keto-PGF1alpha by RIA method.

RESULTSMuscular tissue of group A was normal. But that of group B and C was aberrant,such as swelling and broken of muscular fiber or infiltration of inflammatory cell. Such histological change of group D was lightly and hyperplasia of blood vessel was found. The contents of IL-1beta, TNFalpha, TXB2 and TXB2/6-keto-PGF1alpha in group D were lower than that of group B and group C. On the contrary, the contents of 6-keto-PGF1alpha in the group D were higher than that of group B and group C. The difference of content of IL-6 between groups was not obvious.

CONCLUSIONZGP could promote not only the dilution and the transportation of inflammatory cell factors,but also the repair and the regeneration of the injured tissue structures. The therapeutic effect of ZGP was not relative to IL-6.

Objective: To observe the effects of acupuncture plus spinal manipulations on the physical functioning and levels of alkaline phosphatase (ALP), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and osteoprotegerin (OPG) in patients with ankylosing spondylitis (AS). Methods: A total of 128 AS cases were allocated into a control group and an observation group using random number table method, with 64 cases in each group. Patients in both groups took sulfasalazine and meloxicam. Patients in the observation group received additional acupuncture plus spinal manipulations. The efficacy, Bath AS functional index (BASFI), Bath AS disease activity index (BASDAI), and the levels of ALP, ESR, CRP and OPG were compared between the two groups after eight weeks of treatment. Results: After treatment, the symptom scores of traditional Chinese medicine in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); the VAS, BASFI and BASDAI scores in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); and the ALP, ESR, CRP and OPG levels in both groups were decreased (all P<0.05), and these levels in the observation group were significantly lower than in the control group (all P<0.05). The total efficacy rate was 92.2％ in the observation group, versus 78.1％ in the control group, presenting a statistical significance (P<0.05). Conclusion: Conventional medication combined with acupuncture and spinal manipulations can improve clinical symptoms, accelerate the recovery of physical functioning, and reduce the ALP, ESR, CRP and OPG levels.

OBJECTIVETo gain an insight into the large intragenic hMSH2 and hMLH1 deletions in Chinese hereditary nonpolyposis colorectal cancer (HNPCC) families.

METHODThe large intragenic hMSH2 and hMLH1 deletions in 17 probands of HNPCC families were detected with multiplex ligation-dependent probe Three large intragenic hMSH2 deletions of examplification (MLPA) and GeneMapper techniques.

RESULTSon 8, exon 1-6, and exon 1-7 were found in three families respectively, and no hMLH1 deletion was found. The deletions accounted for 19% of the total hMSH2 and hMLHI germline pathogenic mutations.

CONCLUSIONSThe incidence of large intragenic mismatch repair (MMR) genes deletions is relatively higher in Chinese families, and hMSH2 deletions may be more common. It is necessary to detect the large intragenic MMR genes deletions in the molecular detection of HNPCC.
