AIM: To elucidate the change in TFF3 mRNA in the lung tissue in chronic obstructive pulmonary disease (COPD) rats. METHODS: A model of rat COPD was established by passive cigarette smoking and intratracheal instillation of lipopolysaccharide. The expression of TFF3 mRNA in the lung tissues was detected by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Through a semi-quantitative pathological analysis, mean lung internal lining interval (MLI) in COPD model group was significantly increased compared with healthy control groups; mean alveolar number (MAN) in COPD model group was significantly decreased compared with healthy control group. The expression of TFF3 mRNA decreased significantly in the lung tissue in COPD model group compared with healthy control group. CONCLUSION: The level of TFF3 mRNA expression is possibly related with lung tissue lesion in COPD rats. [

BACKGROUND: Previous studies have proved platelet-rich fibrin (PRF) with osteoinduction ability, and the centrifugal speed and time to prepare rabbit advanced PRF (A-PRF) with the most similar structure to that of human PRF have been determined.OBJECTIVE: To observe the histological changes during A-PRF-induced osteogenesis.METHODS: Thirty Japanese white rabbits were randomly divided into A-PRF and blank control groups (n=15 per group).The full-thickness defect models were established on the rabbit parietal bone, followed by implanted with A-PRF or nothing, respectively. The model rabbits were killed immediately, at 2, 4, 8 and 12 weeks after modeling, to grossly observe the bone formation, and the histological changes in the defect region were observed through hematoxylin-eosin staining, Masson staining and immunohistochemistry.RESULTS AND CONCLUSION: Unhealed defects were observed in the blank control group. Gross and histological observations showed that the speed, amount and maturity of bone formation in the A-PRF group were significantly better than those in the blank control group immediately, 4, 8 and 12 weeks after modeling (P < 0.05). Our findings suggest that the rabbit skull bone defect is successfully established. A-PRF can induce osteogenesis, and more mature newly born bones appear with time. Additionally, osteoclasts can act with osteoblasts synergically under the A-PRF induction to promote the bone formation.

Objective To observe the curative effectiveness of kidney transplantation on uremic patients complicated with Thalassemia.Methods Forty-six cases of uremic patients complicated with Thalassemia(26 cases of alpha-thalassemia,20 cases of beta-thalassemia)subject to kidney transplan- tation were retrospectively studied as the anemia group.Incidence of delayed graft function restoration, rejection(hyperacute rejection,accelerated rejection and acute rejection)and anemia correction were observed.Time needed for renal function restoration was recorded and creatinine value(Cr)was mea- sured in those patients whose kidney function restored after kidney transplantation.Control group in- cluded 131 cases of kidney transplantation performed concurrently that accompanied with different con- tent of anemia other than thalassemia.Results Incidence of DGF was 26.1% and 23.7% in thalasse- mia group and control group,respectively.Six months after transplantation,39 cases in thalassemia group and 109 cases in control group with follow-up were host and kidney alive.In 6 months,rejection ratio was 30.8% in thalassemia group and 32.1% in control group respectively.Cr value was(121?20)?mol/L and(128?33)?mol/L in thalassemia group and control group,respectively.Ratio of anemia correction in thalassmia and control groups was 79.5% and 76.1%,respectively.No indexes above were found to be statically significantly different between these two groups.Conclusion Uremic patients complicated with thalassemia is suitable for kidney transplantation,with clinical effectiveness similar to those without thalassemia.

Objective To explore the biological characteristics and karyotype of bone marrow-derived mesenchymal stem cells(MSCs)in patients with systemic lupus erythematosus(SLE)and hematopoietic sup- port of MSCs.Methods MSCs were isolated from bone marrow of 11 SLE patients and 6 healthy controls by density centrifugation and adhesive culture in vitro.The surface markers were detected by flow cytometry (FCM).The morphological changes of MSCs were observed in primary and passage cultures.The growth curves were assayed.The karyotype of MSCs was detected by blocking cellular mitosis with colchicines.The MSCs from SLE patients and healthy controls were infused to ICR mice after high-dose chemotherapy.The changes of peripheral blood counts of the mice were recorded.Results Approximately(6～9)?10~9 MSCs from SLE were obtained after 5 passages and their growth was slower than normal controls(P＜0.01).Both groups were positive for CD29,CD44 and CD105,and negative for CD14,CD34,CD45 and HLA-DR.MSCs from SLE had a normal karyotype.MSCs infusions of the two groups were accompanied by no adverse event and the recovery of white blood cell,hemoglobin and platelet count was quicker when compared with the controls(P＜0.05).Conclusion MSCs from SLE have demonstrated abnormalities in expansion in vitro.MSCs from SLE have a normal karyotype.Ex vivo MSCs infusion from SLE patients can support hematopoiesis as normal MSCs.

OBJECTIVE: To investigate the level of H2-Ab1 in the nasal mucosa of mice with allergic rhinitis. METHOD: Twenty-four female 129/sv mice were divided into 2 groups: ovalbumin (OVA) group and control. The allergic rhinitis models were induced by classical method with OVA. After the last challenge, the pathological differences between the two groups were surveyed. The levels of H2-AB1 were measured by ELISA and quantitative real time PCR. RESULT: The expression of H2-Ab1 is higher in subjects with AR than that in controls (P < 0.05). CONCLUSION The levels of H2-Ab1 were highly increased in allergic rhinitis group, which might be associated with the pathogenesis of allergic rhinitis.

This study aims to explore and analyze the condition of concurrent diseases and medicine use of traditional Chinese medicine (TCM) and western medicine among the patients with insomnia. One thousand and sxity seven cases of data from 20 national hospitals' hospital information system (HIS) databases were collected. The frequent concurrent diseases included hypertension (26.9%), brain blood supply insufficiency (24.93%), cerebral infarction (19.49%), blood lipoprotein disturbance (15.28%), coronary heart disease (14.15%), headache (10.68%), chronic gastritis (8.81%), type 2 diabetes mellitus (7.87%), depressive disorder (7.4%) and anxiety disorder (6.65%). The 10 most frequently-used western drugs included alprazolam (35.99%), aspirin (25.4%), olanzapine (24.18%), cinepazide (23.06%), flupentixol & melitracen (18.74%), zolpidem (18.37%), oxiracetam (15.65%), estazolam (15%), aniracetam (13.4%) and piracetam (13.31%). The 10 most frequently-used TCM included Shuxuening injection (16.4%), Shuxuetong injection (15.18%), extract of ginkgo biloba leaf (14.71%), gastrodin (12.46%), Dengzanxixin injection (11.34%), Xueshuantong (8.53%), Danhong injection (6.37%), compound liquorice tablet (5.81%), Sanqi Tongshu capsule (5.72%) and sowthistle-leaf ixeridium injection (5.34%). Among all combined uses, the most frequent western drug use was alprazolam and olanzapine, while combined use of hypnotic drug and Huoxuehuayu formula is the most frequent. This study concludes that the concurrent diseases mainly include cardio-cerebrovascular diseases, metabolic disorders and anxiety-depression disorders, with increasing tendency of diseases types by ages, especially for cardio-cerebrovascular diseases. The most frequently-used hypnotic is alprazolam in the insomnia patients, and it is worth being concerned about the off-label use of olanzapine as an antipsychotic for the treatment of insomnia However, due to the fact that all cases data are from the inpatients, these findings have some limitations.

Objective To investigate the diagnosis and treatment of mucinous cystadenoma and cystadenocarcinoma of the pancreas. Methods The clinical data of 23 patients with pancreatic mucinous cystadenoma or cystadenocarcinoma confirmed by pathology from May 1993 to October 2005 was retrospectively studied. Results Fifteen cases of mucinous cystadenoma, 4 cases of mucinous cystadenocarcinoma, and 4 cases of mucinous cystadenoma with malignancy were included in this data. Ultrasonography, CT, and MRI/MRCP displayed a cystic tumor in 73.7%, 68.8%, and 83.3% of all patients, respectively. The mean diameter of the tumors was 9.4 cm, and the maximum diameter of the tumors was 20 cm. Pancreaticoduodenectomy, distal pancreatectomy and splenectomy, local excision of cystadenoma and other procedures were performed according to the site of tumors. The resectable rate was 82.6%. Twenty-one patients (91.3%) were followed up. All of the 14 patients with mucinous cystadenoma were alive with the follow-up from 4 months to 11 years after operation. Two of the 4 cases of mucinous cystadenoma with malignancy were alive with the follow-up of 5 months and 4 years after operations, while the other 2 died with the survival time of 15 months and 18 months. One patient with mucinous cystadenocacinoma was alive 5 months after operation, while the other 2 died with the survival time of 7 months and 13 months. Conclusion Mucinous cystadenoma has a malignant tendency. As the mucinous cystadenocacinoma is a low malignant potential tumor, the resectable rate is high and prognosis is satisfactory. The excision of total tumor including the surrounding pancreatic tissue is the first choice of the treatment. Pancreaticoduodenectomy, distal pancreatectomy and splenectomy, and other procedures according to the site tumors is feasible.
