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.

Objective To study the expression and prognostic significance of neuroendocrine differentiation markers chromogranin A(CgA)and synaptophysin(SYN) in patients with resectable non-small cell lung cancer(NSCLC).Methods From January 2000 to January 2003,123 patients with NSCLC who received operations were investigated.The resected specimens and clinical data were collected.Immunohistochemical Elivison method was used to detecte the expression of CgA and SYN.Kaplan-Meier survival curve and Cox proportional hazard model multivariate analysis were applied for the prognostic factors. Results The positive expression rates of CgA and SYN were 22%,17.9%,respectively.The expression of SYN was associated with histological differentiation(P=0.001).No significant association was found between NSCLC with neuroendocrine differentiation(NSCLC-ND) and sex,age,smoke index,TNM Stage and pathology classification.No evidence showed the patients with positive expression of CgA or SYN could be tolerant with more cycles of chemotherapy(P=0.406).Kaplan-Meier survival curve indicated the survival had a relation with the expression of CgA and SYN.It was revealed by Cox analysis that SYN(P=0.001),TNM stage(P=0.02)and the maximal diameter of tumor(P=0.049) were independent prognostic factors. Conclusion The patients with NSCLC-ND had a poorer prognosis.SYN may be one of the prognostic factors in patients with NSCLC.

Background Porcine fibrin sealant kit has been widely used in surgery for clotting and woundssealing.It is thought to be a substitution for inert gas and silicone oil in vitrectomy.But whether it produce toxic effect on retina or not after intravitreal injection is still studying.Objective This study aimed to investigate the retinal toxicity of porcine fibrin sealant kit following intraocular application.Methods Vitrectomy was performed on bilateral eyes of 15 pigmented rabbits.Porcine fibrin sealant kit of 0.5 ml was intravitreally injected in the lateral eyes of the rabbits as the experimental group,and equal volume of BSS was used at the same way in contralateral eye as control group.The inflammatory response of eye was observed under the slit lamp and ophthalmoscopy in 1 day,3,7,15,30 days after injection.Schi(o)tz tonometer was used to measure intraocular pressure(IOP) in 1 day,3,7 days,and retinal function was evaluated by electroretinogram (ERG) before operation and 30 days after operation.B-ultrasonic examination was carried out 30 days after surgery.Animals were sacrificed and eyeballs were obtained for retinal histopathological and ultrastructural examination in 30 days after operation.Results Complications appeared in 7 eyes of the experimental group,including cataract in 3 eyes,proliferation vitreoretinopathy and retinal detachment in 5 eyes,endophthalmitis in 1 eye,however,the cataract in 2 eyes and retina injury in 2 eyes were found in 15 control eyes.On the 30 days after injection,no inflammation was found in the 8 eyes without complication in the experimental group and 11 eyes in the control group.The IOP change was insignificant in different groups and various time points (Fgroup =0.008,P =0.929 ;Ftime =3.600 P =0.075).No significant difference was found in a-wave amplitude between groups and various time points(Fgroup =0.728,P =0.405 ; Ftime =0.516,P =0.482),and so was the b-wave amplitude (Fgroup =0.222,P =0.644 ; Ftime =0.057,P =0.814).On the 30th day after operation,arrangement of the retina was regular and no tissue edema and inflammatory cell infiltration were seen in both groups under the light microscope.Transmission electron microscope revealed that the ultrastructures of retinal cells,photoreceptor and retinal pigment cell were normal with the clear subcellular organelle,intact cellular membrane structure and mitochondria in both groups.Conclusions Domestic porcine fibrin sealant kit does not produce toxic effect on retina after intravitreal injection in rabbit.

OBJECTIVETo evaluate the effect of Feiji Recipe (FJR) on quality of life (QOL) of patients with non-small cell lung cancer (NSCLC).

METHODSOne hundred and two patients with NSCLC were randomly assigned into 2 groups. The 61 patients in the combined treated group were given FJR and chemotherapy and the 41 patients in the control group were treated with chemotherapy alone. They were observed for two treatment courses with QOL estimated by EORTC QLQ-C43 questionnaire and FACT-L questionnaire, the two international questionnaires as the tools for measurement, and referred to the traditional evaluating indexes of clinical efficiency.

RESULTSQOL in the combined treated group was improved after treatment with the improvement of scores in all domains, including functional and symptom sub-domain, while it in the control group deprived significantly, showing significant difference between the two groups (P < 0.05). Similar results were also shown in the evaluation of physical performance by Eastern Cooperative Oncology Group (ECOG) and Karnovfsky performance scoring. The gastrointestinal reaction and myelo-suppression were slighter in the combined treated group than those in the control group (P < 0.05), and no significant difference was shown between the response rate of the two groups (P > 0.05).

CONCLUSIONFJR can improve QOL of patients with NSCLC, reduce the adverse reaction of chemotherapy, and improve patients' physical performance.

Objective To summarize the domestic design for placebo acupuncture and the placebo effect and explore an ideal design for placebo acupuncture.Method Three large Chinese databases CNKI, Wan Fang and Vip were searched to systematically review the application of placebo acupuncture in randomized controlled trials published at home in recent 5 years (2011.01—2016.11).Results and conclusions A total of 48 articles were included according the inclusion and exclusion criteria. An analysis was made of the kinds of diseases for acupuncture study, the methods of designing placebo acupuncture, the effects of placebo acupuncture and comparisons with foreign placebo acupuncture. Pain syndrome and insomnia were the main kinds of diseases for acupuncture study, accounting for 10 and 8 articles respectively. Acupuncture needles were the main kind of needles for placebo acupuncture, accounting for 66.6%. Sites beside acupoints were the main positions selected for placebo acupuncture, accounting for 58.3%. Not penetrating the skin predominated in the depth of needle insertion, accounting for 37.5%. The kinds of needles for placebo acupuncture were fewer than abroad. The effects of placebo acupuncture were not superior to those of acupuncture.

Objective To investigate the myocardial damage in rats fed with corn from Keshan disease area added with bean puree. Methods Male Wistar rats were randomly divided into 3 groups according to their body weights, and fed with corn, corn from Keshan disease area added with bean puree, corn from non-endemic area. The GSH-Px activity of vena cardalis blood was examined in 1 and 3 months, rats were sacrificed after being fed for 6 months to examine the heart changes with HE stain. Results The three groups of GSH-Px activity were different in 1 and 3 months respectively(F=23.60,72.46, all P<0.01); GSH-Px activity was (181.58±22.15), (44.76±28.59)U/L in rats fed with corn, was (195.03±17.66), (30.38±3.35)U/L in those fed with corn added with bean puree from Keshan disease area, lower than the group fed with corn of non-endemic area[(340.90±95.42), (125.17±13.64)U/L, all P < 0.01]. But the difference of GSH-Px activity between simple corn group and corn adding bean puree groups of Keshan disease area was not obvious(P>0.05). Myocardial damage incidence of the three groups was 3/9,1/9,2/7. Difference among three groups did not have statistical significance(χ2=1.33, P> 0.05). Conclusions Only corn from Keshan disease area may induce myocardial damage pathology change. Adding bean puree into corn does not increase damage.

OBJECTIVETo study the effects and immunoregulation mechanism of the traditional Mongolian medicine Wuweifengshi capsule on adjuvant arthritis (AA).

METHODWister rats were divided into several groups: normal group, AA model group, Wuweifengshi capsule groups (with low, moderate, high dose of 0.2, 0.4, 0.8 g x kg(-1) x d(-1) respectively), and Zhonglun-5 group (original dose of 1.68 g x kg(-1) x d(-1)). The edema degree, the level of IL-1beta, TNF-alpha, PGE2, NO and MDA and the activity of SOD in serum were detected. Through cell culture, the effects of the medicine on AA rat's splenic cell's multiplication capacity were studied. The influence of celiac macrophage cell culture fluid of AA rats' on C57BL/6J mice thymic cell multiplication capacity under the medicine was evaluated.

RESULTWuweifengshi capsule showed an inhibiting function on the level of IL-1beta, TNF-alpha, PGE2, NO and increased the activity of SOD in serum, but showed no significant influence on MDA. It also inhibited the AA rat's splenic cell's multiplication capacity and the influence of celiac macrophage cell culture fluid of AA rat's on C57BL/6J mice thymic cell multiplication capacity.

CONCLUSIONThe anti-AA effect of Wuweifengshi capsule is possibly due to its inhibition of relevant cytokines and its adjustment of corresponding enzyme's activity and immunization organ's cell multiplication capacity.

BACKGROUNDA new technique developed in 2002, real time endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), has been one of the most important tools in lymph nodes (LNs) staging before lung cancer surgery. EBUS-TBNA was introduced into China in 2008.

METHODSBetween June 2009 and October 2009, 30 patients with mediastinal/hilar lymphadenopathy and thoracic masses previously detected with CT scan underwent EBUS-TBNA without rapid onsite cytological examination.

RESULTSFrom 30 patients, 33 samples were obtained from LNs and seven samples from intrapulmonary lesions. Twenty out of the 23 lung cancer diagnoses were clarified through the procedure, with sensitivity, specificity, positive predictive value, negative predictive value and accuracy being 87%, 100%, 100%, 70% and 90%, respectively. All three false negative cases were found in the first five procedures. Additionally, among the 33 LNs examined, three specimens that had no lymphocytes were also found within the first five procedures. There were no major complications, and the procedures were uneventful.

CONCLUSIONSEBUS-TBNA seems a safe and effective technique in making diagnosis for mediastinal/hilar LNs and intrapulmonary masses. For pulmonologists experienced in bronchoscopy, the sensitivity of the procedure for diagnosing lung cancer should be no less than 90% after the initial five procedures.

BACKGROUNDHyperparathyroidism (HPT) occurs at an early age and has a high disability rate. Unfortunately, confirmed diagnosis in most patients is done at a very late stage, when the patients have shown typical symptoms and signs, and when treatment does not produce any desirable effect. It has become urgent to find a method that would detect early bone diseases in HPT to obtain time for the ideal treatment. This study evaluated the accuracy of high field magnetic resonance imaging (MRI) combined with spiral computed tomography (SCT) scan in detecting early bone diseases in HPT, through imaging techniques and histopathological examinations on an animal model of HPT.

METHODSEighty adult rabbits were randomly divided into two groups with forty in each. The control group was fed normal diet (Ca:P = 1:0.7); the experimental group was fed high phosphate diet (Ca:P = 1:7) for 3, 4, 5, or 6-month intervals to establish the animal model of HPT. The staging and imaging findings of the early bone diseases in HPT were determined by high field MRI and SCT scan at the 3rd, 4th, 5th and 6th month. Each rabbit was sacrificed after high field MRI and SCT scan, and the parathyroid and bones were removed for pathological examination to evaluate the accuracy of imaging diagnosis.

RESULTSParathyroid histopathological studies revealed hyperplasia, osteoporosis and early cortical bone resorption. The bone diseases in HPT displayed different levels of low signal intensity on T(1)WI and low to intermediate signal intensity on T(2)WI in bone of stage 0, I, II or III, but showed correspondingly absent, probable, osteoporotic and subperiosteal cortical resorption on SCT scan.

CONCLUSIONHigh field MRI combined with SCT scan not only detects early bone diseases in HPT, but also indicates staging, and might be a reliable method of studying early bone diseases in HPT.
