OBJECTIVETo explore the relationship between aquaporin 3,4 (AQP3, AQP4) gene expression in gastric mucosa and severity of Pi-Wei damp-heat syndrome (PWDHS) in patients with chronic superficial gastritis (CSG).

METHODSGastric mucosa taken from the upper part of gastric corpus was collected under gastroscope and preserved in liquid nitrogen. The gene expression of AQP3 and AQP4 was determined quantitatively by fluorescent PCR.

RESULTSThe gene expression of AQP3 and AQP4 in patients with PWDHS of moderate and severe degree was higher than that in those of mild degree and in healthy persons respectively (P <0.05 and P <0.01); and the gene expression of AQP3 in patients with PWDHS of severe degree was higher than that in those of moderate degree (P<0.05).

CONCLUSIONThe gene expression of AQP3 and AQP4 in gastric mucosa was correlative with the severity of PWDHS in patients with chronic superficial gastritis, the severer the syndrome, the higher the gene expression.

Objective To evaluate the feasibility of active breathing control (ABC) in conformal radiotherapy (CRT) for patients with non-small cell lung cancer (NSCLC). Methods From Feb 2005 to Mar 2008, 29 patients with inoperable NSCLC (stage Ⅱ-Ⅳ) were evaluated. For each patient, two series of CT scans were obtained with free breathing (FB) and ABC system during simulation, respectively. Then two confonnal radiotherapy (CRT) plans were finished based on the two sets of reconstructed images. The pattern of post-inspiratory breath-hold was triggered at 80% of the peak of inspiration curve. The margin of clinical target volume (CTV) to planning target volume (PTV) was 0. 6 cm for lesions of the superior lobe, and 1.0 cm for the lesions of middle and inferior lobes. Three to five coplanar fields were performed in conformal radiotherapy. The gross tumor volume (GTV), CTV, PTV, volume of the bilateral lungs (Volume_(lung)), V_(20) and mean lung dose (MLD) of two plans were evaluated by dose-volume histogram (DVH). The World Health Organization criteria and National Cancer Institute Common Toxicity Criteria 3.0 (NCI-CTC3.0) scale were used to assess the immediate response and acute side-effect, respectively. Results Significant differences of GTV, CTV, FIN, Volum_(lung), V_(20) and MDL were observed between the two plans (36. 35 cm~3 vs. 31.40 cm~3, t = 9. 70, P <0. 001 ;82. 33 cm~3 vs. 70. 83 cm~3, t = 8. 19, P < 0. 001 ; 230. 73 cm~3 vs. 197.59 cm~3 ,t=5.72,P <0. 001 ;21.66% vs. 18. 76% ,t = 11.16,P <0. 001 ;1329. 07 Gy vs. 1143. 14 Gy, t = 13. 24, P < 0. 001). With ABC, all patients completed their treatment successfully except one patient for financial problems. The median radiation dose to the GTV was 64 Gy (60 -64 Gy). The overall immediate response rate was 64% (18/28). According to the NCI-CTC 3.0, grade 1 and 2 acute radiation-related toxicities occurred in 68% (19/28) and 18% (5/28) of patients for esophagitis, 82% (23/28) and 7% (2/28) for pneumonitis, respectively. Grade 1, 2 and 3 bone marrow suppression occurred in 57% (16/28), 25% (7/28) and 14% (4/28) of patients, respectively. Grade 1 and 2 acute cardiac injuries occurred in 86% (24/28) and 14% (4/28) of patients. Conclusions During CRT for patients with NSCLC, the use of ABC can decrease the radiation dose and acute complications of normal tissues.

Objective: To observe the influence of moxibustion sertma of mice on the expression of Fas, bcl-2 mRNA and protein of EL-4 lymphoma cells in vitro. Method: The EL-4 lymphoma cells were cultivated for 24 h in the moxibustion serum of mice. The expression of Fas and bcl-2 mRNA of EL-4 lymphoma cells were detected by in-situ hybridization method, and the protein expression of Fas and bcl-2 were observed by the immuocytochemistry method. Results: The expression of bcl-2 mRNA and protein decreased, and the expression of Fas rnRNA and protein increased significantly in EL-4 cells, which were cultivated in the moxibustion serum compared those cultivated in normal mice serum (P<0.05). Conclusion: Moxibustion serum could down-regulate the bcl-2 mRNA and protein and up-regulate the Fas mRNA and protein of EL-4 cells.

Objective To investigate the efficacy and toxicity of conventional fractionated three-dimensional conformal radiotherapy (3D-CRT) on unresectable hepatocelluar carcinoma(HCC).Methods Fifty two patients with unresectable HCC,all without extrahepatic metastases,were treated by 3D-CRT conducted 5 times a week with the total radiation dose of 36-66 Gy and a daily dose of 2 Gy.The curative effect was evaluated by CT scan to observe the maximum tumor size.Survival rates,survival time,and adverse responses were recorded.Results The total effective rate of the 52 patients was 69.2％ with complete response (CR) in 2 patients and partial response (PR) in 34 patients.The incidence rate of radioactive hepatitis was 1.92％.The 1-,2-,3-,and 4-year survival rates were 57.7％,34.6％,23.1％,and 9.61％ respectively,and the median survival time was 10.5 months.The 1-,2-,3-,and 4-year local control rates were 67％,51.5％,32.3％,and 2.24％,and the 1-,2-,3-,and 4-year distant metastasis rate were 17.2％,23.5％,36.7％,and 76.9％ respectively.The intrahepatic metastases rate was 62.5％ and 37.5％ of the patients suffered from extrahepatic metastasis,including metastases of lung,bone,and retroperitoneal lymph nodes.The remission rate of the≥50 Gy group was 76.9％,significantly higher than that of the ≤50 Gy group (46.2％,x2 =10.72,P ＜ 0.05 ).There was no grade 3 or 4 acute toxicity,and two patients (3.84％) developed gastric or duodenal ulcer.Conclusions Conventional fractionaled 3D-CRT evokes a rather effective response for unresectable HCC with acceptable toxicity.Radiation dose seems to be a significant prognostic factor in RT response for HCC.

OBJECTIVETo observe the effect of Kanli Granule (KG) on myocardial mechanics in pressure overload induced diastolic heart failure (DHF) rats.

METHODSTotally 60 male Wistar rats were divided into the sham-operation group, the model group, the KG group, and the Valsartan group according to random digit table, 15 in each group. The pressure overload induced DHF model was established in all groups except the sham-operation group using abdominal aortic constriction surgery. Totally 7 rats died after modeling (with the mortality of 10. 67%) , and the rest 53 finished the following test. Rats in the KG group were administered with KG extract (calculated as 6. 75 g crude drug/kg) by gastrogavage. Rats in the Valsartan group were administered with Valsartan (7.2 µg/g) by gastrogavage. Equal volume of double distilled water was administered to rats in the model group and the sham-operation group by gastrogavage. All rats were intervened for 32 weeks. The response of isolated heart papillary muscle tonus to isoprenaline (ISO) and adenylate cyclase (Forskolin) was respectively observed. The enhancement phenomenon after resting development force (DF) of isolated heart papillary muscle tonus, and changes of DF in different Ca²⁺ concentrations were observed.

RESULTS(1) In the ISO response test: Compared with the sham-operation group, the amplifications of DF, ±df/dt, -df/dt were obviously elevated in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously lowered in the KG group (P < 0.01), and the amplification of ±df/dt was also reduced in the Valsartan group (P < 0.01). (2) In the Forskolin response test: Compared with the sham-operation group, the amplifications of DF and ±df/dt obviously increased in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously reduced in the KG group (P < 0.01), and the amplification of DF was also reduced in the Valsartan group (P < 0.05). (3) In post-resting DF enhancement test: Compared with the sham-operation group, the amplification of DF showed gradually decreasing tendency along with prolonged resting time in the model group, and they were obviously lowered at all time points (P < 0.05). Compared with the model group, the amplification of DF was gradually increasing along with prolonged resting time in the KG group. The amplification of DF at post-resting 240 s was obviously larger in the KG group than in the model group (P < 0.05). The amplification of post-resting DF still showed gradually decreasing tendency along with prolonged resting time in the Valsartan group, with increased amplifications of DF at post-resting 60 s and 120 s (P < 0. 05) (4) The amplifications of DF in different Ca²⁺ concentrations: Compared with the sham-operation group, the amplifications of DF were significantly elevated in different Ca²⁺ concentrations (1.75, 3.5, 7.0 mmol/L ) (P < 0.05, P < 0.01). Compared with the model group, there was no statistical difference in amplification of DF in different Ca²⁺ concentrations in the KG group (P > 0.05). The amplifications of DF in different Ca²⁺ concentrations were significantly reduced in the Valsartan group (P < 0.05).

CONCLUSIONSThe ISO response and the Forskolin response were enhanced in isolated heart papillary muscle tonus of pressure overload induced DHF rats; enhanced post-resting DF was reduced; DF in different supra-physiologic levels of Ca²⁺ was still enhanced. KG could significantly improve excessive enhancement of pressure overload induced DHF rats in ISO response and Forskolin response, and improve enhancement of post-resting myocardium.

Hemiplegics after stroke are often disabled in sit-to-stand(STS).This article discussed the biomechanics of STS in the hemiplegic stroke patients,in terms of kinematics,kinetics and surface electromyography,and the rehabilitation for the stroke patients with STS dysfunction.It was found that the stability,duration,symmetry of support and degree and se-quence of muscular activation were different when the patients finished the STS task in three foot positions of natural, symmetrical and unaffected foot behind.The early STS rehabilitation training or other rehabilitation may improve the function of the hemiplegic lower extremity to prevent falls and apraxia.

BackgroundThe meibomian gland carcinoma is an eyelid malignant tumor with a domestic incidence after basal cell carcinoma.Meibomian gland carcinoma is not sensitive to radiation therapy and chemotherapy,and the related factors with its recurrence and metastasis are rarely reported.ObjectiveThis study was to investigate the clinical and pathologic features of meibomian gland carcinoma with multiple operations and the effectiveness of histologically controlled excision.MethodsThe clinical data and the histopathologic sections of 34 cases of the meibomian gland carcinoma diagnosed by pathology were retrospectively analyzed at Zhongshan Ophthalmic Center in September 2003 to April 2011,and the treating effectiveness of histologically controlled excision was evaluated. ResultsIn this group of cases,the appearing rate of the meibomian gland carcinoma was resemble in both lateral eyes.A higher morbidity was on the upper eyelid (26/34,76.5％) and then the lower eyelids (5/34,14.7％ ) and both (3/34,8.8％).The average ages of these cases were 57.5 years old.Sixteen of 21 misdiagnosed cases were identified as chalazion at the first visit,and no histopathological examination was performed in 11 cases after initial operation.Twenty-six cases(76.5％ )were identified as meibomian gland carcinoma in initial histopathologic diagnosis.Two cases had histologically controlled excision and 16 cases had simple excision while 16 cases had chalazion enucleation in the first operation.All the patients had histologically controlled excision in Zhongshan Ophthalmic Center with 58.8％ of the patients having pagetoid invasion.Sixteen cases were followed up for 5 months to 8 years after histologically controlled excision,in which none died of recurrence and metastasis of meibomian gland carcinoma.No significant differences were found in the pathological feature between 16 lost patients and 18 followed-up patients(P ＞ 0.05 ).Conclusions Misdiagnosis of meibomian gland as chalazion is a main cause of repeat operations of meibomian gland carcinoma.Histologically controlled excision is a feasible therapy for the recurrence and metastasis of meibomian gland carcinoma.
