Objective To investigate the carotid intima-media thickness(C-IMT) in type 2 diabetes mellitus(T2DM) and the relationship with risk factors. Methods From 2002-01 to 2003-03, we measured C-IMT by B-mode ultra-sonography in 67 patients with different durations of T2DM. Blood was drawn from patients for the analysis of serum creatinine and C-reactive protein(CRP). 24-hour urine collection was performed to determine the level of urine creatinine clearance. Results C-IMT in patients increased with durations and with decreasing creatinine clearance. Multiple regression analysis revealed that C-reactive protein significantly and independently affected the C-IMT. Conclusion C-IMT increases with durations of T2DM and with BMI of the patients. CRP is the risk factor for carotid atherosclerosis in T2DM.

Objective To study the clinical, imageological and pathologic characters of primary synovial chondromatosis of hip joint, and effect of open surgery. Method 12 cases of primary synovial chondromatosis of the hip joints admitted from May 1973 to May 2004 were retrospectively studied in respect to clinical manifestations, X-ray picture, and pathological findings. The effects of operation were followed up. Results Intermittent pain, swelling, limitation of hip joints were the main complaints. Mass and myatrophy near involved hip joint were discernible in a few patients. Although there was no obvious image of calcification, swelling of articular capsule was seen in X-ray film in 4 patients. CT scan showed arthroedema, loose bodies and bone erosion of the femoral head in the hip joint. The X-ray films of the other 8 patients showed obvious calcified loose bodies. All cases were diagnosed by pathology after operations. 8 cases were categorized Milgram Ⅱstage, and 4 cases Milgram Ⅲ stage. Eight patients were followed-up for a period of 1 to 7 years (mean 5 years). Recurrence occurred in 2 cases. Conclusion The diagnosis should be based on clinical characters, X-ray films and pathologic findings, and the pathology is most reliable. In order to decrease recurrence, CT or MRI examinations should be taken before the operation. X-ray monitoring should be carried out during the operation of the patient in whom loose bodies were found in X-ray film before the operation.

To assess early treatment for fracture of the maxillofacial bone complicated by cerebral injury, 120 patients were retrospectively reviewed. The change in GCS, the incidence of stress ulceration, nosocomial pneumonia and the injury of liver or kidney were determined 1 week after fixation of the fracture of the maxillofacial bone at different stages. There was no significant influence of the time of the operation on the severity of brain injury and the incidence of the complications. It is our assertion that the bone fracture could be fixed at an earlier stage, and RIMF is a kind of satisfactory fixation method.

AIMTo develop a rat model of insulin resistanc e,and to study the effect of puerarin injection on expression of protein kinase B in insulin resistanc e rats. METHODS30 SD rats were randomly divded into two groups. The model group were given the high fat diets(0 30 pig fat, 0 10 sucrose, 0 0 3 cholesterol) for 8 weeks. Then 9 rats of the group had been choosen as the pu erarin treatment group and were given abdominal injection (100 mg?kg -1 ?d -1 ) for 4 weeks. By the end of the experiment, Western blot and computer i mage pattern analyze system were used to analysis expression of PKB in skeletal muscles. RESULTS(1) The model group showed a hyperglycemia, hype rinsulinism and obviously visceral obesity by high fat-feeding, the insulin res istance index (ISI) decreased while the HOMA insulin resistance index (HOMA-IR) increased compared to the normal group, insulin resistance was induced in this way; (2) Compared with the pathology control group:fasting blood glucose (FBG), fasting insulin (FINS), visceral fat mass and the HOMA insulin resistance index (HOMA-IR) of the treating group were significantly decreased whereas the insuli n index (ISI) enhanced. Expression of PKB was markedly increased by puerarin tre atment. CONCLUSIONPuerarin injection can significantly elevate e xepression of PKB and ameliorate the state of insulin resistance. Improved biolo gic effect of insulin and prevention of the deleterious effect of fat may be in volved in the mechanism concerned.

Objective To explore the T‐SPOT .TB technology in latent tuberculosis infection (LTBI) who immunosuppres‐sive therapy results in screening for latent tuberculosis infection prevention and control to provide a new basis .Methods Applica‐tion of T‐SPOT .TB kit 162 immunosuppressed patients need to be applied to detect M .tuberculosis‐specific T cells ;while doing all cases tuberculin (TST ) skin test ;of which 28 cases of T‐SPOT .TB‐positive patients before screening technique using anti‐TNF‐αbiologics were given prophylactic treatment of anti‐TB drugs for 4 months and followed a year .Results The positive rates and ac‐curacy rate of T‐SPOT .TB assay were 36 .4% and 94 .9% ,while the positive rates and accuracy rate of TSTs were 28 .4% and 69 .6% .The difference between T‐SPOT .TB assay and TST were statistical significance(P < 0 .05) .Through our 28 cases of T‐SPOT .TB positive screening technology ,prophylactic anti‐TB drugs to treat patients for 4 months and 1 year of follow‐up ,no case of tuberculosis occurred .Conclusion These results demonstrate that the performance of T‐SPOT .TB is better than the classic TST for detection of LTBI in patients receiving immunosuppressive therapy for treatment of systemic autoimmune disorders .The T‐SPOT .TB assay will be a useful tool in early and rapid diagnosis of latent tuberculosis infection .T‐SPOT .TB for LTBI patients di‐agnosed with prophylactic anti‐TB drug treatment is necessary ,has important clinical significance .

Objective:To observe the efficacy of acupuncture at points of Shaoyang meridians plus moving cupping on neck and shoulder for migraine. Methods:A total of 64 migraine cases were randomly allocated into an observation group and a control group, 32 cases in each group. Random number table method was used in allocation. Acupuncture at points of Shaoyang meridians and cupping on neck and shoulder were used for cases in the observation group, which contain acupuncture 5 times a week and cupping once a week. Oral flunarizine hydrochloride capsules were used for cases in the control group, 10 mg for each dose, 1 dose a day. 2 weeks constitutes a course of treatment. The patients were treated for two courses of treatment in both groups. After that, the changes of visual analogue scale (VAS) and the migraine disability assessment questionnaire (MIDAS) were observed, as well as the clinical efficacy. Results:The total effective rate and recovery and marked effective rate in the observation group were 93.8% and 71.0% respectively, versus 78.1% and 43.8% in the control group, showing statistical significant differences (both P<0.05). There were significant decreases in VAS and MIDAS scores after treatments in both groups (both P<0.05). VAS and MIDAS scores in the observation group were significantly different from those in the control group (both P<0.05). Conclusion: Combining acupuncture at points of Shaoyang meridians and cupping on neck and shoulder can relieve headache and reduce influence of migraine on life. It can produce a better efficacy than oral flunarizine hydrochloride capsules in treating migraine patients.

BACKGROUND:Thyroid cancer stem cells are one of the reasons for tumor resistance that promotes tumor development. The research of thyroid cancer stem cells has provides a new clinic means for the diagnosis and treatment of thyroid cancer. OBJECTIVE:To overview the discovery, identification, and correlation of thyroid cancer stem cells with thyroid cancer. METHODS:A computer-based online search of PubMed database and Wan Fang database between 1995-01/2014-01 was performed to search related articles with the key words of“thyroid cancer, cancer stem cell, stem cell, cancer suppressor gene”in English and Chinese, respectively. Literatures related to thyroid cancer stem cells were selected;in the same field, the articles published lately in authoritative journals were preferred. RESULTS AND CONCLUSION:A total of 561 literatures were primarily selected, and 57 documents were involved for result analysis according to inclusion criteria. Cancer stem cells have become a focus in the study of carcinogenesis. Stem cells also exist in the thyroid gland and its tumor. At present, there are several ways to isolate and identify thyroid cancer stem cells. The tumor thyroid stem cells are closely related to the occurrence, transfer and treatment of tumors. But whether we can cure thyroid cancer through restraining or eliminating thyroid cancer stem cells is stil unknown that needs further studies.
