To explore the characteristics and influenced factors associated with the onset of vertigo disease, analysis of 3 719 cases of hospitalized patients with vertigo disease from the real world. Analysis the date of patients diagnosed with vertigo disease from the hospital information system of 19 grade-III class-A hospital from 2004 to 2011, include general information, the doctor's advice, other diseases combined, diagnostic information and the relationship with the onset of 24 solar terms, and the treatment drugs. The median age of hospitalized patients with vertigo disease was 59, the number of women (65.91%) was more than men (34.09%), manual workers (85.32%) were the majority career, most patients (81.63%) condition were general by the time they were hospital admission, patients more like admitted to neurologist (70.34%) when they first time to outpatient serves, hospitalization days were in 8-14 days (46.65%), 46.04% of the patients in the hospital total cost is in 5 000 RMB to 10 000 RMB, 73.86% of patients paid by National Health Medical Insurance. Hypertension (20.79%) was the most common underlying health problems, The most common syndromes was deficiency of liver-Yin and kidney-Yin(44. 21%) , followed by hyperactivity of liver-yang, disease of phlegm turbidity in mongolia and deficiency of Qi and blood. There were more deficiency syndrome and less excess syndrome. The highest rate of hospital admission solar terms in 2009 was the insects awaken throttle (5.21%), In 2010, the highest rate solar terms of hospital admission was the rain throttle (6.14%). The most frequently used traditional Chinese medicine was gastrodine injection (20.55%), the most frequently used western medicine for betahistine (10.19%), gastrodine injection was the most traditional Chinese medicine that combination with other western medicine. Hypertension was the most underlying health problems in the patients with vertigo disease in the real world, although the mental factors should also be attention. Liver was the most closely internal organs with vertigo, and solar terms in spring was the highest-frequency time. Gastrodine injection was the most commonly used traditional Chinese medicin in clinical to treat vertigo diserse, the therapeutic regimen combining with traditional Chinese and western medicine has more advantages. We should pay more attention to the guidance of Chinese medicine "syncretism between heaven and man", to keep up with the rhythm of change, adapt to the changes in the human body growth and decline of the Yin and Yang, by adopting the method of syndrome differentiation in traditional Chinese medicine to prevention and treatment vertigo disease.

OBJECTIVETo investigate the efficacy and safety of chemotherapy combined with intraperitoneal perfusion of cytokine-induced killer (CIK) cells for advanced gastric cancer patients with ascites.

METHODSFrom January 2008 to December 2010, 42 advanced gastric cancer patients with ascites in Zhongshan Hospital of Fudan University were enrolled in the study. According to personal choice, patients were divided into 2 groups: XELOX chemotherapy alone (Capecitabine and Oxaliplatin) was applied in 22 patients (chemotherapy group) and XELOX combined with intraperitoneal perfusion of CIK cells in 20 patients (combination group). The efficacy, safety, and immunological function, including the time to progression (TTP), overall survival (OS), Karnofsky performance status (KPS) score, immunity index (CD4+/CD8+ ratio), volume of peritoneal fluid, were compared between two groups.

RESULTSCompared with the chemotherapy group after treatment, the combination group had a higher KPS score (78.0±9.8 vs. 70.0±8.9, P=0.009), less volume of 2-cycle peritoneal fluid drainage [(4500±1218) ml vs. (5527±1460) ml, P=0.018 ], longer median TTP (4.0 vs. 2.5 months, P=0.001) and OS (11.0 vs. 6.0 months, P=0.006), higher ratio of CD4+/CD8+ (1.34±0.36 vs. 0.96±0.26, P=0.001). While no significant significances were found between the two groups in disease response rate (35.0% vs. 22.7%, P=0.499) and disease control rate (75.0% vs. 54.5%, P=0.209). There were no serious adverse reactions in the combination group.

CONCLUSIONSAs compared with XELOX chemotherapy alone, the combination immunological treatment of XELOX chemotherapy and intraperitoneal perfusion of CIK cells possesses better efficacy for the advanced gastric cancer patients with ascites, which can prolong the survival and enhance the immunological function with favorable safety.

This study was purposed to prepare eukaryotic expression vector of recombinant human platelet CD36 gene. The total RNA was extracted from human liver tissue and the cDNA encoding human platelet CD36 antigen extracellular region (Gly30-Asn439) was amplified by RT-PCR. The cDNA was cloned into the prokaryotic expression vector pMD18 and the recombinant vector was transformed into E. coli DH5α. The positive recombinant pMD18-CD36 plasmid was screened. After sequencing, this combinant vector was inserted into the transient eukaryotic expression vector pTE2, the pTE2-s-CD36-10 His transient eukaryotic expression vector was constructed. The recombinant CD36 Gly30-Asn439 expressed by HEK-293 cells was purified with Ni(2+) 2NTA chromatography. The results showed that 1.4 kb cDNA was amplified by RT-PCR, sequencing of the cDNA indicated the sequence was exactly the same to that in Genbank NM_001001547.2. The HEK293 cells with the plasmid were transfected, and SDS-PAGE confirmed that the transfect HEK293 cells expressed the human CD36 antigen extracellular protein fragments. Western-blot showed that the monoclonal antibody could recognize the recombinant CD36 with the sensitivity of 8 ng. It is concluded that the CD36 Gly30-Asn439 can be highly expressed by human embryonic kidney cells (HEK293), and the monoclonal antibody with biological activity has been obtained, which provide the basis for further study on platelet transfusion refractoriness.

BACKGROUNDBladder urothelial cancer has been diagnosed at an increasing rate among young adults in China while the clinical outcomes remain highly controversial. To optimize the management of young patients with bladder cancer, we examined whether bladder urothelial cancer in young patients behaved differently from that in the elder patients.

METHODSFrom 1994 to 2008, a database of bladder urothelial cancer patients at a major tertiary medical center was retrospectively reviewed. The clinical and pathological parameters of patients who were less than 40 years of age and a series of patients older than 40 years of age as the control group during the same period were compared. A survival analysis was performed using the Kaplan-Meier method and log-rank test, and Cox regression was performed to identify clinical parameters that affected the clinic outcomes.

RESULTSYoung bladder cancer patients had a lower male-to-female ratio and were less likely to have advanced stages and high-grade cancers at the initial diagnosis. Tumors in young bladder cancer patients tended to be less multifocal at diagnosis. In addition, young patients had a lower recurrence rate and longer recurrence interval than older patients. The Kaplan-Meier curve and Log-rank test showed that young patients had significantly better cancer specific survival than old patients. The univariate and multivariate Cox regression analysis revealed that tumor grade is the sole predictor for tumor recurrence in young patients.

CONCLUSIONSYoung patients with bladder cancer have favorable pathological features and clinical outcomes than older patients. These findings argue for more conservative management approaches for young patients with bladder cancer.

OBJECTIVESTo explore the clinical, pathological features and prognosis of patients with chromophobe renal cell carcinoma.

METHODSFrom January 1998 to January 2008, clinical data of 29 patients with chromophobe renal cell carcinoma including clinical manifestations, imaging examinations, treatment models, pTNM stages and follow-up results, were summarized to investigate its features and prognosis.

RESULTSAll cases had no obvious clinical and preoperative imaging presentation. There were 23 patients underwent radical nephrectomy, and 6 cases underwent nephron sparing surgery. Postoperative pathological findings confirmed the diagnosis of chromophobe renal cell carcinoma. Macroscopically, the cut surface of the tumors were generally beige in color. Histologically, it showed polygonal chromophobe cells and small round eosinophilic cells with eccentric hyaline degeneration. These tumor cells had a clear and sharp membrane, lightly stained abundant cytoplasm with a fine reticular translucent pattern and irregular nuclei. And a perinuclear halo was often seen in these cells. Histochemically, the tumor cells generally show a diffuse and strong reaction for CK-8 with a negative expression of Vimentin. The pTNM stages of the tumor were as follows, pT1N0M0 in 11 cases, pT2N0M0 in 8 cases, pT3aN0M0 in 5 cases, pT1N1M0 in 3 cases, pT2N1M0 in 2 cases. Twenty-six cases of patients were followed up (24 to 144 months, with an average of 90 months), 3 cases died of cardio-cerebrovascular disease, and local recurrence involved in 6 cases with reoperation in 4 cases, as well as distant metastasis in 1 case. Twenty-one cases survived with tumor-free. The statistical results indicated that the survival rates of the patients with chromophobe renal cell carcinoma in five years and ten years were 83.9%, 77.9%, respectively, compared with renal cell carcinoma of the same stage 63.8% and 49.9% at the same periods, and there is no difference in the survival rate of five years (P > 0.05) but significant difference in that of ten years (P < 0.01).

CONCLUSIONSChromophobe renal cell carcinoma is a morphologically uncommon subtype of renal cell carcinoma with the good prognosis. Definite diagnosis depends on its typical pathological feature. Radical nephrectomy is the first choice for the treatment of chromophobe renal cell carcinoma.

This study was aimed to analyze the serological characteristics, efficacy and safety of incompatible RBC transfusion in patients with autoimmune hemolytic anemia (AIHA). The patients with idiopathic or secondary AIHA were analyzed retrospectively, then the serological characteristics and the incidence of adverse transfusion reactions were investigated, and the efficacy and safety of incompatible RBC transfusion were evaluated according to the different autoantibody type and infused different RBC components. The results showed that out of 61 cases of AIHA, 21 cases were idiopathic, and 40 cases were secondary. 8 cases (13.1%) had IgM cold autoantibody, 50 cases (82.0%) had IgG warm autoantibody, and 3 cases (4.9%) had IgM and IgG autoantibodies simultaneously. There were 18 cases (29.5%) combined with alloantibodies. After the exclusion of alloantibodies interference, 113 incompatible RBC transfusions were performed for 36 patients with AIHA, total efficiency rate, total partial efficiency rate and total inefficiency rate were 56.6%, 15.1% and 28.3%, respectively. Incompatible RBC transfusions were divided into non-washed RBC group and washed RBC group. The efficiency rate, partial efficiency rate and inefficiency rate in non-washed RBC group were 57.6%, 13.0% and 29.4%, respectively. The efficiency rate, partial efficiency rate and inefficiency rate in washed RBC group were 53.6%, 21.4% and 25.0%, respectively. There was no significant difference of transfusion efficacy (P > 0.05) in two groups. Incompatible RBC transfusions were also divided into IgM cold autoantibody group and IgG warm autoantibody group. The efficiency rate, partial efficiency rate and inefficiency rate in IgM cold autoantibody group were 46.2%, 30.8% and 29.4%, respectively. The efficiency rate, partial efficiency rate and inefficiency rate in IgG warm autoantibody group were 56.7%, 13.4% and 29.9%, respectively. There was no significant difference of transfusion efficacy (P > 0.05 ) in two groups. Hemolytic transfusion reaction was not observed in all incompatible RBC transfusions. It is concluded that the same ABO type of non-washed RBC transfusion and O type washed RBC transfusion are all relatively safe for the AIHA patients with severe anemia after the exclusion of alloantibodies interference. There is no significant difference of transfusion efficacy in two groups. The same ABO type of non-washed RBC transfusion is more convenient and efficient than washed RBC transfusion, and excessive use of type O RBCs can also be avoided.

The purpose of this study was to investigate the impact of leucine-rich repeats and immunoglobulin-like domains 3 (LRIG3) on the biological features of bladder cancer cell lines. The plasmids of over-expressed LRIG3 and the blank plasmid serving as control were transfected into the bladder cancer cell lines, T24, EJ and BIU-87, and the expression levels of LRIG3 mRNA and protein were detected by using real-time PCR and Western blotting. The changes in the cell cycle and apoptosis were examined by using flow cytometry. The invasive ability was measured by Transwell assay, and CCK-8 assays were used to measure the proliferation of cells. As compared with the control group, the LRIG3 mRNA and protein expression levels in LRIG3 cDNA-transfected group were raised significantly (P<0.05). The average number of cells with up-regulated LRIG3 passing through the inserted filter was decreased significantly as compared with the control group (P<0.05). Up-regulation of LRIG3 also could inhibit proliferation and induce apoptosis of T24, EJ and BIU-87 cells. Except BIU-87, the T24 and EJ cells transfected with LIRG3 cDNA were arrested in G(0)/G(1) phase compared to the control group (P<0.05). In conclusion, the over-expression of LRIG3 could influence the cell cycle and invasion, inhibit proliferation and induce apoptosis in the three bladder cancer cell lines.
