Background: Radiation pneumonitis is one of the most common complications during radiotherapy of thoracic tumors. It impacts the quality of life of the patients and has life-threatening danger. However, there is a lack of drugs for prevention and treatment of this disease. Objective: To evaluate the efficacy of Liangxue Jiedu Huoxue Decoction, a compound traditional Chinese herbal medicine, in prevention of radiation pneumonitis. Design, setting, participants and interventions: A prospective randomized clinical study was conducted. A total of 100 patients diagnosed with lung cancer from Department of Radiotherapy, Chinese PLA General Hospital, who were planning to receive radiotherapy, were randomly assigned into treatment group and control group, with 50 patients in each group. In the treatment group 3 cases were lost to follow-up and one case was excluded, while in the control group 6 cases were lost to follow-up and 2 cases were excluded. Patients in the treatment group were treated with Liangxue Jiedu Huoxue Decoction in addition to radiotherapy, while patients in the control group were treated with radiotherapy alone. Main outcome measures: The incidence rates of radiation pneumonitis in the two groups were calculated. Acute radiation injury scoring criteria by Radiation Therapy Oncology Group (RTOG), clinical-radiographic-physiologic (CRP) score system, and Karnofsky Performance Status Scale (KPS) were used to evaluate the status of the patients. Results: The incidence rate of radiation pneumonitis was lower in the treatment group than in the control group (13.04% versus 33.33%, P<0.05). According to the RTOG scale, the extent of lung injury was improved in the treatment group as compared with that in the control group (P<0.05). The CRP score in the treatment group was significantly lower than that in the control group (P<0.05). The KPS score in the treatment group was significantly higher than that in the control group (P<0.05). Conclusion: Liangxue Jiedu Huoxue Decoction can decrease the incidence rate of radiation pneumonitis, reduce the extent of the lung injury, alleviate the symptoms of radiation pneumonitis, and improve life quality of the patients.

The influence of inner cell mass (ICM) and trophectoderm (TE) score on pregnancy outcomes in frozen-thawed blastocyst transfer cycles was analyzed. A retrospective analysis of 741 cycles of frozen-thawed blastosysts transfer was performed. All cycles were divided into four groups based on the number and morphological score of blastocysts: S-ICM B/TE B group (n=91), the single blastocyst transfer of ICM B and TE B; D-ICM B/TE B group (n=579), double blastocysts transfer of ICM B/TE B; D-ICM B/TE C group (n=35), double blastocysts transfer of ICM B/TE C; and D-ICM C/TE B group (n=36), double blastocysts transfer of TE B/ICM C. The pregnancy outcomes were compared among the four groups. As compared with D-ICM B/TE C group, the clinical pregnancy rate, implantation rate and multiple pregnancy rate were increased in D-ICM B/TE B group (74.96% vs. 57.14%, 57.43% vs. 37.14%, and 48.62% vs. 25%, respectively, P<0.05 for all). Clinical pregnancy rate and implantation rate in D-ICM B/TE B group were also higher than in D-ICM C/TE B group (74.96% vs. 50%, and 57.43% vs. 33.33%, both P<0.05). Multivariable Logistic regression analysis indicated that ICM score was a better predictive parameter for clinical pregnancy (OR=3.05, CI 1.70-5.46, P<0.001), while the trophectoderm score was a better one for early abortion (OR=0.074, CI 0.03-0.19, P<0.001). Clinical pregnancy rate and multiple pregnancy rate in S-ICM B/TE B group were significantly lower than those in D-ICM B/TE B group (46.15% vs. 74.96%, and 2.38% vs. 48.62%, both P<0.05), but there was no significant difference in the implantation rate between the two groups. It was suggested that the higher score of ICM and TE may be indicative of the better pregnancy outcomes. The ICM score is a better predictor of clinical pregnancy than TE, while TE score is a better one in predicting early abortion. Single ICM B/TE B blastocyst transfer in frozen-thawed cycles can also get satisfactory pregnancy outcomes.

Objective To explore the influence of 300 g/kg high protein diet on myelination of the intrauterine grow retardation (IUGR) in the rat brain and their learning and memory ability.Methods The pregnant rats were fed with 60 g/kg low protein diet.After birth,the offspring of IUGR group were fed separately by 300 g/kg high-protein diet (SH group) and 210 g/kg normal-protein diet(SC group).Forty newborn female pups,born from pregnant rats fed by normal-protein diet,were used as the control group(CC group).On the first,the 7th,the 15th and the 218t day,the body weight,brain weight of the offspring and their dynamics expressions of myelin basic protein(MBP) in corpus callosum,internal capsule and external capsule were observed with immunohistochemistry method.Morris water maze test was performed to assess learning and memory ability during the 26th-32ed,then the expression of MBP in the brain was observed.Results On the 21st day,the SH group gained catch-up growth weight,while the brain weight of them was still lower than that of the CC group (P ＜ 0.05),but higher than that of the SC group.At each time point,the MBP expression in corpus callosum,internal capsule and external capsule of SH group and SC group was lower than that of the CC group(all P ＜0.05),whereas the expression of myelin basic protein in the SH group was higher than that in SC group.The average latencies in all rats were reduced to some degree from the first to the 5th day.On the 5th day,there was no significantly difference between the SH group and CC group (P ＞ 0.05),while the escape latency was significantly shorter in rats of SH group than those of SC group (P ＜ 0.05).As far as search strategy was concerned,there was no difference in SH group and SC group of rats(P ＞ 0.05),but they performed better than those in the SC group on the 5th day(P ＜0.05).The frequency of passing through the platform quadrant was not significantly difference in rats among the 3 groups (P ＞ 0.05).Conclusions 300 g/kg high-protein diet on IUGR rats can increase brain weight and the expression of MBP,and improve the ability of learning to some extend.

Objective To observe the role of rosiglitazone in unclipped kidneys of two-kidney- one-clip hypertensive rats and examine its relationship to angiotensinⅡreceptors.Methods Two- kidney-one-clip hypertensive rats were divided randomly into 4 groups as follows:positive control group (CONT),traditional antihypertensive drugs group (TAHD,reserpine 50?g?kg~(-1)?d~(-1), dihydralazine 6.25 mg?kg~(-1)?d~(-1) and hydrochlorothiazide 6.25 mg?kg~(-1)?d~(-1),regular-dose rosiglitazone group (RRGL,rosiglitazone 5 mg?kg~(-1)?d~(-1)),and high-dose rosiglitazone group (HRGL, rosiglitazone 20 mg?kg~(-1)?d~(-1)).Sham operation rats were as negative controls.Each group had 8 rats. Animals were monitored and sacrificed at 10th week.Results Blood systolic pressure in TAHD group and HRGL group was significantly lower than that in CONT group [TAHD(137?27 ) mm Hg and HRGL (143?16) mm Hg vs CONT (191?25 ) mm Hg,P＜0.05],but no significant difference between the former two groups was found.Nor did the blood systolic pressure between RRGL group [(176?18) mm Hg] and CONT group.At 10th week,rats in SHAM group and treated groups had lower urinary urinary protein excretion rate,glomerular injury score and wall-to-lumen ratio of arteriole than those in CONT group [vs CONT urinary protein excretion rate (44.60?17.40) mg/24 h,P＜0.05; vs CONT glomerular injury score 60.85?33.05,P＜0.05;vs CONT wall-to-lumen ratio of arteriole 2.33?1.01,P＜0.01,except TAHD group].Though with the similar level of blood pressure,blood glucose and lipid,HRGL,compared with TAHD group showed lower urinary protein excretion rate [HRGL (16.78?3.50) mg/24 h vs TAHD (27.94?12.79) mg/24 h,P＜0.05],decreased glomerular injury score (HRGL 18.04?7.76 vs TAHD 27.92?6.39,P＜0.05) and wall-to-lumen ratio of arteriole (HRGL 1.75?0.38 vs TAHD 2.16?0.90,P＜0.05) in the cortexes of unclipped right kidneys.The expression of type 1 angiotensinⅡreceptor (AT1R) mRNA was no difference in HRGL group and TAHD group,but the expression of type 2 angiotensinⅡreceptor (AT2R) mRNA was more intensive in HRGL group.Conclusion Rosiglitazone can protect the kidneys from hypertensive injury,especially in high dose.The beneficial effects seem incompletely dependent on the metabolism modulating and reduction of blood pressure,but in relationship to the upregulation of AT2R mRNA.

Objective In order to improve the understanding of Kimura's disease,the clinical features and the pathological changes of 12 patients were analyzed.Methods Twelve cases with Kimura's disease ad- mitted to Qilu Hospital of Shandong University were retrospectively reviewed.Results All 12 patients were in relatively good condition and presented as subcutaneous nodules or swelling lymph nodes.Peripheral blood eosinophilia did not occur in 5 cases,4 out of 6 patients had high-level serum IgE.Biopsies were taken in all cases and the characteristic histological presentations were discovered.Only one patient developed pulmonary inflammation and acute myocardial infarction which were rare in Kimura's disease.Conclusions Definite di- agnosis of Kimura's disease mainly relies on biopsy.A patient with Kimura's disease can suffer from severe pulmonary and cardiac diseases,but the relationship between them should be studied further.

Objective To determine the therapeutic effect of recombined rat insulin-like growth factory 1 gene and transforming growth factor beta-1(TGF-?_1)gene on anterior cruciate ligament transection(ACLT)- induced osteoarthritis-like changes in NZW rabbit knee joints.Methods Eighteen NZW rabbits were divided into 3 groups randomly after osteoanhritis was established by ACLT and another six rabbits were used as normal control group(group 1).Chondrocytes which had been transfected with IGF-1 gene,co-transfected with TGF-?_1 and IGF-1 gene(group 3,4)were injected into the rabbits knee joints.Experimental control group(group 2)only had ACLT bul was not transfected.After 4,8 weeks,rabbits were sacrificed and their joints were evaluated by morphological grades,histological examination,in situ hybridization examination,immunohistochemistry exami- nation,and transmission electron microscopy examination(TEM).Results The morphological grades showed that the normal control group had a very significant difference with the experimental control group(P

Objective To evaluate the effect of staged repair for tetralogy of Fallot (TOF) associated with pulmonary artery hy- poplasty.Methods From June 1996 to June 2006,37 patients with TOF were operated on.There were 26 males and 11 females. Their age was 5 months to 17 years(mean 3.6 years) and weight was 4.6～38.0 kg.All patients were diagnosed as TOF with pulmo- nary artery hypoplasty by cardiac catheterization.The mean pre-operative arterial saturation of the patients was (68.2?6.5) %,Mc- Coon ratio was 0.95?0.26 (0.81～1.17) and Nakata index was 82.7?21.6(71.6～97.5) mm~3/m~2.At the time of the first surgi- cal procedure,17 patients underwent central aortopulmonary shunt,13 patients received modified Blalock-Taussig shunt in the left side and 7 patients had modified Blalock-Taussig shunt in the right side.Results There were no easly operative deaths and no late deaths after the first stage repair.Pleural effusion after shunt occurred in 5 patients.The mean arterial saturation was significantly increased to (91.3?10.4) %,P

OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.

METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.

RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.

CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.
