OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

Objective To observe the long term effects of arthroscopic knee debridement and reconstructing operation for treating osteoarthritis in patients with Kaschin-Beck disease. Methods Thirty-one cases of patients with Kaschin-Beck disease were followed for 6 years after operation of articular clearing by arthroscope. Index of pain, symptoms of self-evaluation, range of motion, walking distance, standing test by affected leg when bending at 30° or 60° were recorded and compared with the preoperative results. Results Twenty-four cases were followed up for 6 years. Six years after operation the pain index(3.38 ± 2.87) was dramatically decreased compared to that before operation (6.88 ± 1.45, t = 5.30, P ＜ 0.05). Patients symptoms markedly improved by subjective self-evaluation was 70.83% (17/24), the effective rate was 100% (24/24). The number of cases that could stand up when leg bending at 30° or 60° were 21,18 cases, respectively, compared with that of preoperative of 14, 11 cases, respectively, the difference was statistically significant(x2 = 5.17,4.27, all P ＜ 0.05). Six years after operation the walking distance(3 cases ＜ 1 km, 11 cases 1 - 5 km and 10 cases ＞ 5 km) were greatly improved compared to the results before operation (12 cases ＜ 1 km, 9 cases 1 - 5 km and 3 cases ＞ 5 km, U = 2.88, P ＜0.05). Six years after operation the knee activity[(132.25 ± 14.52)°] remained at the same level, compared with that of preoperative [(131 .58 ± 14.68) °], the difference was not statistically significant (t = 0.16, P ＞ 0.05) .Conclusions The method of arthroscopic joint debridement to cure Kaschin-Beck disease knee osteoarthritis can significantly reduce pain, improve function and walking distance, with more stable long-term satisfactory outcome.

OBJECTIVEIBS-D rat model was established to assess the effect of Shen warming Pi strengthening method (SWPSM) for intervening diarrhea-predominant irritable bowel syndrome (IBS-D) by observing rats' general state, stool properties, AWR ranking, and histopathological changes.

METHODSTotally 72 rats were randomly divided into 6 groups, i.e. the normal group, the model group, the high, middle, low dose SWPSM groups, and the control group, 12 in each group. The IBS-D rat model was successfully established referring to AL-Chaer ED's modeling method. After modeling high, middle, and low dose SWPS Recipe boil-free granules were given by gastrogavage to rats in corresponding treatment groups. Sishen Pill boil-free granule was given by gastrogavage to those in the control group. Equal volume of normal saline was given by gastrogavage to rats in the model group. The medication lasted for 2 weeks. Rats' general state, stool properties, abdominal withdrawal reflex (AWR) ranking, and histopathological changes were observed.

RESULTSAfter treatment, the general state of all rats got im- provement to various degrees. The improvement in the high and middle dose SWPS Recipe groups were superior to that in the low dose SWPS Recipe group and the control group (P < 0.05). There was no statistical difference in the growth rate between after and before treatment in each group (P > 0.05). Compared with the model group and the low dose SWPS Recipe group, the defecation amount within 4 h was less in the high and middle dose SWPS Recipe groups and the control group (P < 0.05). The Bristol ranking score, average ranking of loose stool, ratio of dry stool and wet stool were lower in the high and middle dose SWPS Recipe groups than in the control group and the low dose SWPS Recipe group (P < 0.05). The AWR ranking score was lower in the high and middle dose SWPS Recipe groups than in the control group when the volume of balloon dilation was 1.5 mL. There was no organic change of histological or morphological observation.

CONCLUSIONSHigh sensitive IBS-D model was proved to be reliable. SWPSM could reduce the quantity of stools, lower Bristol ranking score, average ranking of loose stools as well as ratios of dry stool and wet stool, contributing to reducing the high sensitivity of rats' visceral organs to some extent.

AIM:To explore the effect of curcumin(Cur)and curcuminoids(Y20 and 6B)on the expression of secretory leukocyte protease inhibitor(SLPI), tumor necrosis factor-α(TNF-α)and interleukin-1β(IL-1β)induced by Streptococcus pneumoniae(SP)and the possible mechanism.METHODS:BEAS-2B cells incubated with SP were set up as an inflammation model of pneumonia.The mRNA levels of SLPI at 1 h,3 h,6 h and 9 h,and the mRNA expression of TNF-αand IL-1βat 3 h,6 h and 9 h in control group,SP infection group,Cur treatment group,Y20 treatment group and 6B treatment group were measured by qPCR.The protein levels of TNF-αand IL-1βin the culture supernatant were measured by ELISA.The protein levels of Toll-like receptor 2(TLR2)and phosphorylated nuclear factor-κB(p-NF-κB) p65 at 3 h,6 h and 9 h were determined by Western blot.RESULTS:The mRNA level of SLPI was increased in Cur, Y20 and 6B treatment groups compared with SP group(P<0.05).The protein levels of TLR2 and p-NF-κB p65 were sig-nificantly increased after SP stimulation.After treatment with Cur,Y20 and 6B,the protein levels of TLR2 and p-NF-κB p65 were significantly decreased(P<0.05).The levels of TNF-αand IL-1βwere significantly increased after SP stimula-tion.Cur,Y20 and 6B significantly decreased the levels of TNF-αand IL-1βin the supernatant(P<0.05).CONCLU-SION: Cur, Y20 and 6B increase SLPI expression, reduce the expression of inflammatory cytokines TNF-αand IL-1β. The possible mechanism might be associated with inhibiting TLR 2 expression and down-regulating the transcriptional activity of NF-κB.

OBJECTIVETo explore the essential points for diagnosis of pulmonary embolism in children with mycoplasma pneumonia.

METHODRetrospective analysis of the clinical and laboratory data of a pediatric case who developed pulmonary embolism after mycoplasma pneumonia was performed for the key points for diagnosis.

RESULTA-six-year old boy was admitted with chief complaint of fever and cough for half a month, combined with chest pain and mild labored breath. Vital signs were stable. Breathing movement of the left side weakened and there was left lower lobe percussion dullness. Breath sound was found weakened in the left lung, and a few fine crackles were audible. The results of laboratory tests were as follows: mycoplasma antibody (IgM) 1:128, cold agglutinin test 1:1024, blood D dimer 14.81 mg/L; anticardiolipin antibody was positive; plasma protein C activity was 60% (normal range 70% - 130%). Pulmonary artery computed tomographic angiography revealed a mass opaque shadow in left lower lobe, the branch of left lower bronchial artery was partially obstructed. Echocardiography showed tricuspid valve mild regurgitation, estimated pulmonary pressure was 5.1 kPa. Single-photon emission computed tomography indicated that radioactivity distribution was apparently sparse in the dorsal segment, anterior basal segment, outer basal segment and inferior lingular segment of the left lung. The preliminary diagnosis on admission was mycoplasma pneumonia with pleural effusion, pulmonary embolism. Intravenous erythromycin combined with meropenem were administered. Anticoagulation therapy was initiated with low molecular weight heparin and then oral warfarin tablets. Pleural effusion disappeared soon, D dimer descended to 0.38 mg/L, and pulmonary artery pressure declined. After 3-month follow-up, anti-cardiolipin antibody was negative, plasma protein C activity recovered, and lung lesions were absorbed.

CONCLUSIONWhen mycoplasma pneumonia is accompanied by chest pain or dyspnea and there are bloody pleural effusion, pulmonary hypertension, positive antiphospholipid antibody and elevated D dimer, pulmonary embolism should be considered. Diagnosis could be clarified by the result of pulmonary artery computed tomographic angiography.

OBJECTIVETo study the relationship between influenza epidemic and genetic characteristic on HA and NA regions of influenza virus subtype A3 isolates of Zhejiang province in the recent years.

METHODSRNA of 25 influenza virus subtype A3 isolates, circulated in Zhejiang province during 1998 to 2005, was extracted. HA1 and NA regions were amplified and sequenced. All the sequence data were analyzed using BioEdit.

RESULTSHA1 and NA regions of all the isolates belonged to 987nt and 1362nt, encoding protein of 329 and 454 amino acids respectively. Isolates shared amino acid homology of 90.9%-99.3% and 95.2%-99.5% on HA1 and NA regions, while divergence on HA1 was greater than that on NA region. During a period of 8 years, 30 amino acids on HA1 region were substituted and 14 of which refer to 4 antigenic determinant sites. Meanwhile,21 amino acids on NA region were substituted and 5 of which referred to 3 antigenic determinant sites. Significant divergences, both in HA1 and NA, were observed among isolates in 1998 and 2002, showing that they belonged to absolutely different branches. Additionally, influenza virus subtype A3 isolates identified in recent years, with 11 N-linked glyeosylation sites in HA1 region, had 5 sites more than early A/Aichi/2/68 strain. Since 1998,3 sites had been inserted in epidemic strains, indicating the accelerated trend of glyeosylation sites were increasing.

CONCLUSIONThere is a correlation between antigenic drift of influenza virus subtype A3 and the two epidemics in Zhejiang province in 1998 and 2002.
