Objective To investigate the curative effect of brucellar spondylitis,so as to provide scientific proof for improving the curative level of the disease.Methods Epidemiological information was collected from 113 patients diagnosed as brucellar spondylitis,who were divided into 5 groups according to different drugs and drug combinations of doxycycline,gentamicin,sulfamethoxazole and rifampicin.Then the curative effect was investigated.Twenty-one patients who had greater paoas muscle abscess or Para vertebral abscess,intraspinal abscess of spinal canal,necrotic intervertebral disk and major osteolasia received the minimal invasive surgery and the focus removal surgery.Results The occurrence of the disease in female was much higher than that in male.Grazing and breeding beasts was the principal route of infection.Lumbars was mostly involved.they usually was infected in the adjacent 2 piece.L4 was the most common and seriuous one.The curative effect of doxycycline group was better than that without doxycycline(72.60% vs 35.00%,X2=15.14,P＜0.05).Doxycyeline+gentamicin+sulfamethoxazole was reeommended as the first choice.However,the curative effect did not increase despi~course of the treatment prolonged.The heMing rate and effective rate after 1 course was 52.21%(59/113)and 92.04%(104/113).that after 2 courses 58.41%(66/113)and 95.58%(108/113),that after 3 courses 59.29%(67/113)and 95.58%(108/113).The healing rate in different course did not present differences(P＞0.05).21 patients undergoing surgery were followed-up,12 patients were after 2 years and 9 patients were between 1-2 years.The healing rate was 95.24%(20/21),1 case was healed basically,the effective rate was 100%.None reoccurred.Conclusions There are characterized features in clinical epidemiology of the brucell spondylitis.Long term,adequate in dosage,combination and multi-approach use of antibiotics is the most reliable way to treat and prevent it from recurring.But fof the patients soitable for surgery.the minimal invasive surgery or the focus removal could shorten the course of therapy,decrease the complications and increase the cure rate.

Abstract: Mycobacterium senegalense is one of the major pathogens causing bovine farcy, and reports of its infection in human are rare. Here is a report on a woman who had been taking hormones and immunosuppressants for a long time for SLE and underwent abdominal soft tissue infection with Mycobacterium senegalense after abdominal liposuction, to provide reference for clinical diagnosis and treatment. The patient, female, 32 years old, has a history of SLE for more than 2 years, and currently takes "methylprednisolone, hydroxychloroquine, and mycophenolate mofetil" regularly. Nine months before the patient was admitted to the hospital, she once performed abdominal, waist and buttock liposuction in a medical beauty institution. One month after the operation, several masses gradually appeared on the abdominal wall, accompanied by tenderness, one of the masses had obvious fluctuation on palpation and purulent fluid could be drawn out. The location of the abdominal wall mass was consistent with the insertion site of the liposuction needle. After the onset of the disease, the patient went to the medical beauty institution for puncture of the abdominal wall mass, and 5 mL of purulent fluid was pierced and sent for bacterial culture, and cultured "Mycobacterium Senegalense", after 3 days of treatment with "cephalosporin" antibiotics (specifically unknown), the symptoms did not improve, so she went to the second affiliated hospital of hainan medical college. After completing the relevant examinations during the hospitalization in our hospital, in order to clarify the etiology, another abdominal puncture to extract pus was performed, the mycobacterial culture + identification results: Mycobacterium senegalense. Consistent with the out-of-hospital results, the diagnosis of Mycobacterium senegalense infection was confirmed. After 3 months of treatment with "cefoxitin, azithromycin, amikacin, and levofloxacin", the patient's abdominal wall soft tissue infection was cured. Trauma or invasive procedures can lead to skin, muscle, or bone infection with nontuberculous mycobacteria (NTM), which can manifest as chronic painless nodules that progress to purulent folliculitis and abscesses. NTM infection should be suspected when the patient's wound has been exposed to water, there is a history of surgery, and empirical anti-infection is ineffective. This is the first case of Mycobacterium senegalense infection caused by medical beauty, which tell people that they should be cautious when choosing medical aesthetic projects and medical aesthetic institutions.

Decoction is one of the most commonly used dosage forms of traditional Chinese medicine. The stability of chemical constituents in decoction is closely related to the clinical efficacy and safety. There were few reports about the influence of metal ions in the stability of chemical constituents in traditional Chinese medicine. However, there is no evidence that metal ions in decoction water need to be controlled. In this study, 2,3,5,4'-tetrahydroxy stilbene-2-O-β-D-glucoside (THSG), one of the main constituents in Polygoni Multiflori Radix was studied. Ordinary tap water, deionized water, and water containing different metal ions were used to investigate and compare the influence on THSG. The results showed that after storage in a dark place at the room temperature for 10 days, the degradation of THSG was 7% in deionized water, while undetectable in tap water. The content of THSG could be decreased by different kinds of metal ions, and the effect was concentration-dependent. Moreover, Fe3+ and Fe2+ showed the greatest influence at the same concentration; and our study has shown that THSG decreased more than 98% in Fe and Fe2+ solutions at 500 ppm concentration. In the same time we found out p-hydroxybenzaldehyde (molecular weight: 122.036 7) and 2,3,5-trihydroxybenzaldehyde-2-O-glycoside (molecular weight: 316.079 4) were the main degradation products of THSG in tap water and water containing Cu2+, Ca2+, Zn2+, Mg2+ and Al3+. The product of THSG dimer with a water molecule was found in water containing Fe3+ and Fe2+. The above results showed that the metal ions in water could significantly influence the stability of THSG in water, indicating that the clinical efficacy and safety of decoction would be affected if the metal ions in water were not under control. It's suggested that deionized water should be used in the preparation of decoction containing Polygoni Multiflori Radix in the clinic to avoid degradation of THSG. Meanwhile, decoction prepared by tap water should be taken by patients in a short time. Our investigation provides important information and reference about the influence of metal ions on the stability of decoctions in other traditional Chinese medicine that have unstable groups such as hydroxyls and unsaturated bonds, etc.

In this study, the inhibitory effect of human umbilical cord-derived mesenchymal stem cells (hUCMSC) on interleukin-17 (IL-17) production in peripheral blood T cells from patients with spondyloarthritis (SpA) were investigated, in order to explore the therapeutic potential of hUCMSC in the SpA. Peripheral blood mononuclear cells (PBMNC) were isolated from patients with SpA (n = 12) and healthy subjects (n = 6). PBMNC were cultured in vitro with hUCMSC or alone. The expression of IL-17 in CD4(+) T cells or γ/δ T cells were determined in each subject group by flow cytometry. IL-17 concentrations in PBMNC culture supernatants were measured by ELISA. The results indicated that the proportion of IL-17-producing CD4(+) T cells and IL-17-producing γ/δ T cells of SpA patients were 4.5 folds and 5 folds of healthy controls [CD3(+)CD4(+)IL-17(+) cells (3.42 ± 0.82)% vs (0.75 ± 0.25)%, P < 0.01; CD3(+)γδTCR(+)IL-17(+) cells (0.30 ± 0.10)% vs (0.06 ± 0.02)%, P < 0.01]. After co-culture of PBMNC in patients with hUCMSC, the increased proportions of CD3(+)CD4(+)IL-17(+) cells and CD3(+)γδTCR(+)IL-17(+) cells in SpA patients were inhibited significantly by hUCMSC [CD3(+)CD4(+)IL-17(+) cells (3.42 ± 0.82)% vs (1.81 ± 0.59)% (P < 0.01); CD3(+)γδTCR(+)IL-17(+) cells (0.30 ± 0.10)% vs (0.16 ± 0.06)% (P < 0.01]. In response to phytohemagglutinin (PHA, 1 µg/ml), PBMNC from SpA patients secreted more IL-17 than that from healthy control [(573.95 ± 171.68) pg/ml vs (115.53 ± 40.41) pg/ml (P < 0.01)]. In the presence of hUCMSC, PBMNC of SpA patients produced less amount of IL-17 [(573.95 ± 171.68) pg/ml vs (443.20 ± 147.94) pg/ml, (P < 0.01)]. It is concluded that the IL-17 production in peripheral blood T cells from SpA patients can be inhibited by hUCMSC, which have therapeutic potential for SpA.

OBJECTIVETo evaluate the feasibility and the clinical practicality of the design about the hollowed titanium stick supporting the femoral head and preventing it from collapsing.

METHODSFrom Jan.2003 to Jun.2007, 36 patients (46 hips) diagnosed as cystis degeneration of the femoral head were treated by surgical operation, including 20 males and 16 females with an average age of 40 years ranging from 18 to 56 years old, and the course of the disease was from 10 to 24 months (16 months on average). According to ARCO staging,there were 24 patients (34 hips) in NFH II, of which 11 hips were II a stage, 13 hips were II b stage and 10 hips were II c stage; there were 6 patients diagnosed as osteofibrous,4 patients as simple bone cyst and 2 patients as chondromyxoid fibroma. Under X-ray the percutaneous narrow core decompression and focus infection elimination were performed and supported the sclerotin under the cartilage with titanium stick. The patients were followed-up at the first, third, sixth, twelfth, twenty-fourth and thirty-sixth month after the operation. The clinical evaluation was done by X-ray and the indexes included stable, unstable and abortive. The data was analyzed by Fisher exact probility and the suviaval rate was analyzed by Kaplan-Meier suviaval curve using statistical soft ware SPSS13.5.

RESULTSThere were no unstable or failure cases on each period from the 1st month to the 12th month after the operation, indicating that the supporting effect of the titanium stick was exact during 12 months after the operation. There were unstable and failure cases from the 12th month to the 24th month after the operation, which were mainly in stage NFH II c but the comparision of the stable rate in this period and 12 months after the operation had no obvious statistical differences (P>0.05) indicating that the supporting effect of the titanium stick was feasible during the stage. One of the unstable cases deteriorated and failed but there were no new unstable cases, both the stable rate and the unstable rate had no change and the failure rate rose on the 36th month after the operation. The compar- ision of the stable rate on each period after the operation had no obvious difference (P=0.197>0.05), which indicated that the supporting effect of the titanium stick was persistent. By the difference of the etiology the three-year survival rate of the relevant NFH II c pathological changes was the lowest-70% and the survival rate of the pathological changes induced by other etiological factors was 90.2%.

CONCLUSIONThe design about the hollowed titanium stick supporting the collapsed femoral head is feasible. Using the hollowed titanium stick to support the femoral head and prevent it from collapsing is pragmatic in the clinical and the effect is positive, however, when it comes to the NFH II c pathological changes, the choice should be made discreetly.

Aim To investigate the mechanism by which ginsenoside Rgl regulates autophagy anrl delays brain aging in mice through AMPK/mTOR signaling pathway.Methods C57BL/6J male mice were ran¬domly divided into four groups, namely brain aging model group ,control group, Rgl anti-aging group,auto¬phagy activator Rapamycin anti-aging group.After the modeling was completed, the test of each experimental index would be carried out on the next day.Morris wa¬ter maze experiment was used to detect the learning and memory ability of mice.Paraffin sections of the hippocampus were prepared, HE , Nissl and immunohis- tochemical staining were used to observe the morpholo¬gy of hippocampal neurons, the number of neurons and Nissl bodies was counted, and autophagy-related proteins p62 , ATG5 , ULK1 were detected.Brain tissue homogenates were prepared to detect the aetivity of brain tissue acetylcholinesterase ( AChE ).Western blot was userl to detect brain tissue autophagy-related proteins LC3II, P62, beclinl, P-AMPK/AMPK, P- mTOR/mTOR and apoptosis protein P53.Results Water maze test showed that Rgl and Hap significantly improved the learning and memory abilities of brain-ag¬ing mice.HE and Nissl staining showed that Rgl and Rap decreased necrotic cells and increased the number of Nissl bodies in the hippocampus of brain-aging mice.Immunohistochemistry staining showed that Rgl and Rap decreased the expression of neuronal autoph- agv protein P62 in hippocampus and increased the ex-pression of ATG5 and ULK1.Rgl and Rap decreased the activity of AhcE in brain-aging mice.Western blot showed that Rgl and Rap increased autophagy-related proteins LC3II, Beclinl , P-AMPK/AMPK, but de¬creased the expression of P-mTOR/mTOR, P62, P53.Conclusions Ginsenoside Rgl can effectively antago¬nize the aging effect of D-gal on mouse brain.The pos¬sible mechanism is related to the regulation of autoph- agv by Rgl through AMPK/mTOR signaling pathway.

Ge Gen Decoction (GGD), a Traditional Chinese Medicine prescription, is mainly used to treat infectious respiratory diseases and can relieve the symptoms of influenza A virus (IAV) infection. However, the underlying mechanism of GGD against IAV infection remains unclear. In this study, we found that GGD had moderate anti-IAV activity in vitro. GGD was more effective when given before the viral infection and targeted the viral attachment and replication stages rather than the internalization stage. In vivo, GGD treatment reduced thevirus titers of lung tissue significantly and improved the survival rate, lung index, and pulmonary histopathological changes in H1N1-infected mice. We observed the changes in several key immuno-related indexes in GGD administrated H1N1-infected mice with anti-IAV drug oseltamivir phosphate as the control. GGD treatment decreased the expression of TNF-α and improved Th1/Th2 immune balance to reduce the excessive immune response in H1N1-infected mice. Besides, the expression of the toll-like receptor 7 signaling pathway in H1N1-infected mice decreased after GGD treatment. Our results showed that GGD has anti-IAV activity and can modulate the immune system to relieve lung inflammation.

OBJECTIVETo assess the test-retest reliability and criterion validity of the Simplified Chinese-character version of the International Physical Activity Questionnaire Long form (IPAQ-L) in urban community-dwelling adults in Hanghzou, China.

METHODSA total of 158 eligible participants aged 25-59 years from 6 neighbourhoods in two central districts of Hangzhou completed the IPAQ-L questionnaire twice within a 7-day interval. Half of the subjects wore pedometers during the first 7 days. Test-retest reliability was examined by comparing the first (Day 1) and the second (Day 9) survey of IPAQ-L. Criterion validity was assessed by comparing IPAQ-L with pedometer data.

RESULTSModest to good test-retest reliability was found with intraclass correlation coefficients of 0.67 for total PA, 0.37 to 0.73 for specific dimensions, and 0.56 to 0.71 for different intensities of PA. Total PA measured by IPAQ-L was moderately correlated with exercise levels (partial r = 0.27, P = 0.020) and walking distance (partial r = 0.31, P = 0.007), which were measured by a pedometer, after adjusting for gender, age, educational attainment and employment status.

CONCLUSIONOur results indicate that the IPAQ-L is a reliable and validated measure for assessing physical activity levels in this population and possibly the adult population in other mainland Chinese cities.
