Objective To analyse the clinical characteristics,therapeutic modalities and prognosis of pulmonary large cell neuroendocrine carcinoma(LCNEC). Methods The clinical data of 14 patients with pulmonary LCNEC confirmed by surgery were retrospectively reviewed. Results No case was correctely diagnosed before surgery.The immunohistochemical amalysis of the specimens revealed the characters of endocrine carcinoma.Twelve cases received adjuvant chemotherapy of platinum agents,but recurrence or metastasis was found in 8 of them several months after surgery.The median survival time was 19 months.The 1-year,2-year and 3-year survival rate were 85.7%(12/14),21.4%(3/14) and not more than 14.3%(2/14),respectively.The statistical analysis showed that the stage,lymph node metastasis and postoperative adjuvant chemotherapy may have impacts on the prognosis of pulmonary LCNEC. Conclusion Pulmonary LCNEC is a carcinoma with poor prognosis,high tendency of invasion and metastasis.The stage of disease,lymph node metastasis,and adjuvant chemotherapy may be related to the prognosis.

OBJECTIVETo compare the efficacy difference in the treatment of chronic pelvic pain syndrome of Sev-damp-heat stagnation pattern between acupoint catgut embedding therapy and western medication.
METHODSenty cases were randomized into a catgut embedding group (40 cases) and a western medication group (30 cases) at the ratio of 4 : 3. In the catgut embedding group, the catgut embedding therapy was applied to Sanyinjiao (SP 6), Quchi (LI 11), Huiyin (CV 1), Zusanli (ST 36), Zhongji (CV 3), Shenshu (BL 23), etc. The treatment was given once every two weeks, the treatment for 4 weeks was as one session and totally 2 sessions were required. In the western medication group, tamsulosin hydrochloride capsules 0. 2 mg, oral administration, once a day, and Indometacin sustained release tablets, 75 mg, once a day, 3 tablets each time were prescribed. The symptom score of TCM, score of NIH Chronic Prostatitis Symptom Index (NIH-CPSI), lecithin body number in prostatic fluid, (SAS) score of Self-Rating Anxiety Scale and score of Self-Rating Depression Scale (SDS) were compared before and after treatment in the patients of the two groups. The efficacy was evaluated in the two groups.
RESULTS(1)The total effective rate was 91. 9% (34/37) in the catgutembedding group and was 86. 2% (25/29) in the western medication group. The efficacy in the catgutembedding group was better than that in the western medication group (P<0. 05). (2) The symptom score of TCM was all reduced significantly after treatment in the two groups (both P<0.01), and the result in the catgut embedding group was superior to the western medication group (6.42 +/-2. 81 vs 10. 99+/-3. 11 ,P<0. 01). (3) Lecithin body number was increased apparently in the two groups after treatment (both P<0.01), and the result in the catgut-embedding group was superior to the western medicine group (33.56+/-5.88 vs 29. 78+/-7. 06,P<0. 05). (4) Total score of NIH-CPSI, score of pain, score of SAS and score of SDS were all improved apparently after treatment in the two groups (all P<0. 01), and the results in the catgut embedding group were superior to the western medication group (P<0. 01, P<0. 05).
CONCLUSIONThe acupoint catgut embedding therapy achieves the superior efficacy on chronic pelvic pain syndrome of damp-heat stagnation pattern as compared with conventional western medicine. This therapy relieves clinical symptoms, improves the states of anxiety and depression and increases lecithin body number obviously.

Objective To study the correlation between 8-Iosmerie Porastglnadin-2a(8-iso-PGF2α) 、hypersensitive C-reactive protein(hs-CRP) and coronary heart disease(CHD). Methods 153 CHD patients were divided into 3 groups,including 52 cases of acute myocardial infarction(AMI) ,50 cases of unstable angina(UAP) ,51 cases of stable angina(SAP) and control group consisted of 50 healthy people. The levels of hs-CRP and 8-iso-PGF2α were measured. Person correlation analysis was used to analyze the relationship between the level of hs-CRP and 8-isoPGF2α. Results The levels of hs-CRP and 8-iso-PGF2α were significantly higher in AMI, UAP and SAP group than those in control group(all P <0.05). Compared with SAP group,the levels of hs-CRP and 8-iso-PGF2α were increased in AMI and UAP groups (all P < 0. 05) . The level of hs-CRP was positively associated with the level of 8-iso-PGF2α. Conclusion hs-CRP and 8-iso-PGF2α should be the markers of coronary atherosclerosis and involved in the process of CHD. The levels of serum hs-CRP and 8-iso-PGF2α were correlated with the severity of CHD.

OBJECTIVETo investigate the relationship of the common Traditional Chinese Medicine (TCM) syndrome pattern of chronic pelvic pain syndrome (CPPS) with the contents of substance p and beta endorphin in the plasma, and provide reference data for the clinical diagnosis, differentiation and treatment of CPPS by TCM.
METHODSWe observed 98 cases of CPPS, which were classified into a lower-part damp-heat invasion group (group A, n = 32), a blood stasis-induced collateral obstruction group (group B, n = 34), and a damp-heat stagnation group (group C, n = 32) according to the TCM syndrome differentiation. Another 35 normal healthy young men were enrolled as controls. We measured the contents of substance p and beta endorphin in the plasma by immunoradiometry and ELISA, and analyzed their relationship with the TCM syndrome pattern.
RESULTSThe contents of plasma substance p were significantly higher in groups A ([1135.76 +/- 166.45] pg/ml), B ([1 337.84 +/- 170.81] pg/ml), and C ([1 210.01 +/- 162.27] pg/ml) than in the control ([574.99 +/- 113.09] pg/ml) (all P < 0.01), while the contents of plasma beta endorphin in groups A ([212.70 +/- 29.49] pg/ml), B ([157.99 +/- 24.01] pg/ml), and C ([180.81 +/- 20.20] pg/ml) were remarkably lower than that in the control ([274.73 +/- 27.64] pg/ml) (all P < 0.01).
CONCLUSIONIn the plasma of CPPS patients, the content of substance p is significantly elevated and that of beta endorphin markedly reduced, which suggests that they may be involved in the inflammatory reaction of CPPS. The levels of plasma substance p and beta endorphin can be used as valuable reference for the TCM classification of chronic prostatitis.

Objective To investigate the effects of naloxone (Na) on pneumocyte apoptosis and expression of heme oxygenase-1 (HO-1) during ischemia reperfusion injury of lung in rats. Method Forty-two male Sprague-Dawley rats were made models of ischemia reperfusion injury of unilateral lung, and were randomly( random number) divided into three groups: sham operation group (Sh group), ischemia reperfusion group (IR group) and naloxone group (Na group). The hilus of lung was clamped for 45 minutes and the clamp was taken off to build the I/R model. After 3-6 hours reperfusion, naloxone in dose of 1 mg/kg was injected intra-peritoneally in rats of Na group. The rate of cell apoptosis in lung tissue was detected with the way of Annexin-V-PI in flow cy-tometer. The wet to dry weight ratio (W/D) of lung tissue was measured. The expression of HO-1 in lung was measured by using RT-PCR and the ultra-structure change of lung tissue was observed under electron microscope. Results The rate of pneumocyte apoptosis and W/D ratio of lung tissue were significantly higher in IR group than in Sh group (P < 0.01), and the rate of pneumocyte apoptosis and W/D ratio of lung tissue were negatively correlated with the expression of HO-1 mRNA in lung tissue. Compared with IR group, the rate of cell apoptosis and W/D ratio were lower and the expression of HO-1 mRNA was higher in Na group (P < 0.01). The ultra- structure changes of lung tissue were lessened in Na group than in IR group. Conclusions During early period of lung IR injury, HO-1 induced by naloxone can inhibit the cellular apoptosis and protect the lung tissue.

Oral mucosal drug delivery has the advantages of rapid drug absorption, no first-pass effect and good patient compliance. However, factors such as low drug dissolution, saliva carrying the drug into the gastrointestinal tract and the existence of physiological barriers in the mucosa may affect the mucosal permeation and bioavailability of the drug. Nanotechnology applied to drug oral mucosa delivery can overcome the above disadvantages and obtain efficient absorption effect. This paper describes the physiological structure of oral mucosa and the factors affecting the absorption of drugs in oral mucosa, reviews the application of nanotechnology such as liposomes, solid lipid nanoparticles, nanostructured lipid carriers, nanoemulsions, polymer nanoparticles, polymer micelles and nanohybrid suspensions in oral mucosal drug delivery and the mechanism of promoting drug absorption, summarizes the main problems of current research, and gives an outlook on the application of nano oral mucosal drug delivery system. The main problems of current research are summarized, and the prospects for the application of nano oral mucosal drug delivery systems are discussed.

OBJECTIVETo study the relationship between compositions of hyperuricemia and metabolic syndrome among residents aged > or =20 years.
METHODSA stratified cluster sampling was conducted with 7887 dwellers recruited and examinaed. Blood samples were then collected for serum detection. Available data was analyzed using SPSS 13.0.
RESULTSThe incidence rates of obesity, hypertension and hyperglycemia for hyperuricemia were 53.4% with OR = 2.568 (95% CI: 2.103-3.137), 38.8% with OR= 2.157 (95% CI: 1.856-2.508) and 21.9% with OR = 1.850 (95% CI: 1.552-2.205) respectively. Along with the increase of uric acid, body mass index changed the most followed by triglyceridemia. The change of hyperglycemia for men and cholesterol for women were not prominent. Conclusion The relationship between compositions of hyperuricemia and metabolic syndrome was close, suggesting that hyperuricemia might serve as one of the compositions of metabolic syndrome and could contribute to the prevention and control of cardiovascular and cerebrovascular diseases.
