The ralationship between traditional Chinese medicine (TCM) and intestinal microecology is increasingly being given more and more attention. Combined with the devolopment of intestinal microecology disciplines, effects of TCM on regulation of intestinal microecology have been gradually explained. Both clinical studies and animal experiments have confirmed that TCM can maintain the balance of intestinal microecology and regulate the intestinal flora. The author arrangemented the documents related to Chinese herbal compound adjusting intestinal flora in the recent ten years, summarized that the Chinese herbal compound which can strength spleen and replenish Qi, relax bowels and regulate Qi, dissipate dampness and check diarrhea, clear away heat and toxic materials, promote digestion and relieve stasis had certain regulation effects on intestinal microecology, providing basis for revealing the TCM essence of intestinal microecology.

Objective To culture human pituitary adenoma cells to provide some useful experimental foundations to practice pituitary adenoma cells as donor cells in the extracranial implantation. Methods Human pituitary adenoma cells obtained by operation were cultured in vitro, and their growth state was dynamically observed. Immunohistochemical staining and RIA were used to evaluate their functional status. Results The cultured pituitary adenoma cells still had secretory function in vitro. 6 cases of GH adenoma cells secreted a large amount of GH, 5 cases of PRL adenoma cells secreted a large amount of PRL, and 3 cases of pituitary adenoma cells without function could also secrete a small quantity of FSH, LH and PRL. Conclusion 14 cases of cultured human pituitary adenoma cells had secretory function in vitro, which provides the useful experimental data to perform extracranial implantation with pituitary adenoma cells as donor cells.

Objective To intelligently adjust the driving force of a remote-controlled drug delivery capsule based on the postural information in intestines,so as to achieve the control of speed and dosage of drug delivery and reduce the energy consuming.Methods A six-axis sensor MPU6050 was used,and its Z axis was coincident with the central axis of the drug delivery capsule so as to made the medicine discharge port pointing to the Z direction.The angular velocities and accelerations of X,Y,Z axes were monitored,transformed to quaternion with built-in digital motion processor,and then converted to Euler angle form.The intelligence adjustment of driving force could be achieved by accessing the real-time attitude angle of the capsule.Results The results of experiments showed that the error between the actual and the attitude angle measured by the sensor was less 1°.Conclusions The intelligent adjustment scheme of driving force of a gastrointestinal remote-controlled drug delivery capsule was designed.The real-time attitude angles of the capsule could be obtained with high spped and precision.This study can provide the theoretical and experimental basis for the intelligent adjustment of the driving force.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

ObjectiveTo evaluate the suitability of Nordtest guideline in estimating measurement uncertainty of routine tests in clinical laboratory.MethodsData of clinical laboratory of Beijing Tongren Hospital were collected,which came from 176 days of Internal Quality Control ( IQC ) from July 2010 to December 2010 and 6 times of External Quality Assesment ( EQA ) of NCCL from 2009 to 2010.The combined and expanded uncertainties of 21meaurements (sodium, potassium, chlorine,calcium,phosphrous,glucose,urea nitrogen,creatinine,uric acid,total protein,albumin,total bilirubin,direct bilirubin, alanineaminotransferase, aspartateaminotransferase, alkalinephosphatase, lactate dehydrogenase,glutamyl transpeptidase,creatine kinase,triglyceride and total cholesterol) were evaluated according to Nordtest guideline.ResultsOf all the measurements,expanded uncertainty of direct bilirubin ( 17.69％ ) was the highest.For some enzymes such as ALT,AST,ALP and LDH,expanded uncertainties were all over 10％ markedly influenced by the calibrator uncertainty.Expanded uncertainty of triglyceride was 12.7％,also largely influenced by calibrator uncertainty,while that of total cholesterol was 6.96％.ConclusionsNordtest guideline is suitable to evaluate the measurement uncertainty of routine assays in clinical laboratory.However,calibrator uncertainty should be taken into account in the process of evaluation.

Purpose To evaluate apoptosis in renal tissue of diffuse proliferative lupus nephritis and therelationship between the existence of apoptosis cells in renal tissue and histopathological or clinical changes.Methods Apoptosis was detected by in situ nick-end labeling techniques (TUNEL) in renal biopsies from 25patients with type Ⅳ LN, 12 patients with IgAN, 4 patients with MsPGN, and 3 patients with APSGN. Normalrenal tissue obtained at nephrectorny for hypemephroma in 4 adults was used as control. In addition, proliferatingcells were identified by proliferating cell nuclear antigen(PCNA) in these patients. Results Compared to otherproliferative glomerulonephritis and control,the patients with lupus nephritis had less apoptosis cells, higher ratio ofPCNA+ cells/TdT+ cells/(P/T) in renal tissues;Ratio of P/T in glomeruli and tubulointerstitium correlated withthe chronicity index, r=0. 498 3(P = 0. 013 2), r = 0. 839 9(P＜ 0.001 ), r = 0. 661 4(P = 0. 003 3),respectively. Ratio of P/T in glomerulus and tubule had positive correlation with 24 hour urinary protein, r =0.855 4(P＜0.001),r=0.713 4(P=0. 001); negative correlation with Ccr, r = - 0. 488 0(P =0. 013 3)and r = - 0. 722 9(P = 0. 001), which in tubules positively correlated with Scr, r = 0. 410 7 (P = 0.041 4 ).Conclusions Apoptosis is insufficient in proliferative lupus nephritis. Intense proliferation without followingincrease in apoptosis may be related to chronic progressive renal histopatholcgical changes.

Objective: Changes in the ?2 integrin of adhesion molecules between cells are closely associated with the invasion and migration of tumor cells.This study aimed at the effect of anti-?2 integrin on the invasion and migration of osteosarcoma MG63 cells. Methods: The osteosarcoma MG63 cell line was cultured in the DMEM medium.The effect of the anti-?2 integrin monoclonal antibody on the migration and invasion of tumor cells were measured by scratch assay and Transwell assay.The migration and invasion cells were stained by Crystal violet staining and counted under the hundredfold microscope.Results: Compared with the control group,the migration and invasion abilities of the MG63 cells were significantly decreased in the anti-?2 treatment groups.Conclusion: Anti-?2 integrin may inhibit the migration and invasion of osteosarcoma cells.

Objective To compare the effects and complications of lumboperitoneal shunt ( LP ) and ventriculoperitoneal shunt ( VP ) in the treatment of post?traumatic hydrocephalus. Methods Eighty patients with post?traumatic hydrocephalus treated in the neurosurgery department of Zhangjiagang Hospital of Traditional Chinese Medicine from March 2014 to March 2010 were retrospectively analyzed. The patients were randomly divided into two groups,40 patients treated with LP were assigned into the LP group and 40 patients undergone VP treatment were seen as the VP group. All patients were followed up for 1 year to investigate and compare the symptom improvement rate,neurological deficit score and the incidence of complication of the two groups. Results The total effective rate of hydrocephalus disappearance in the LP group was 41. 50% ( 37/40) and 87. 50%( 35/40) in the VP group. The difference between the two groups was not statistically significant (χ2=0. 556,P=0. 456);the neurological deficit scores before treatment in the LP group and VP group were (28. 35±8. 64) points and (29. 13±7. 98) points,there was no significant difference between the two groups (t=0. 419,P=0. 676) . The difference in the scores of neurological deficit after treatment in the LP and VP group was not statistically significant ( (19. 32±5. 34) points vs. (21. 62±4. 86) points,t=1. 480,P=0. 143),the average scores of neurological deficits in the two groups were significantly better than those before treatment ( t=5. 623, 5. 084,P<0. 001 ) . There was no significant difference in the average score of improvement of urinary incontinence between the two groups before and after treatment ( t=0. 376,1. 265,P>0. 05) ,the average score of urinary incontinence improvement after treatment in both groups were better than those before treatment ( t=4. 891,5. 370,P<0. 001) . In the LP group,the incidence of bleeding,infection,shunt related complications and shunt abnormality were all 2. 50% ( 1/40 ) , the overall complication rate was 10. 00%, the incidence of bleeding,infection,shunt related complications and shunt abnormality in the VP group were 7. 50% (3/40), 10% ( 4/40 ) , 5% ( 2/40 ) 10%, ( 4/40 ) , the overall complication rate was 32. 50%, there was significant difference between the two groups (χ2=6. 050,P=0. 014) . Conclusion LP and VP have significant curative effect on the treatment of post?traumatic hydrocephalus,but the overall incidence of LP complication after 1 year is significantly lower than that of VP,and is worth popularizing widely in clinical practice
