Forty cases of bronchial asthma were treated by comprehensive methods of acupuncture, ear-embedding and acupoint-injecting. Thirty-six cases were treated by single body acupuncture and 38 cases were treated by herbal medicine for comparison. The therapeutic effects were analyzed among the three groups. The total effective rate was 95.0% in the comprehensive group, 80.6% in the single acupuncture group and 73.7% in the herbal medicine group, with a significant difference (P＜0.05) among the three groups. The combined use of acupuncture, ear-embedding method and acupoint-injecting method were better than single acupuncture and herbal medicine in the treatment of asthma.

Objective To investigate operative methods and indications for the surgical repair of hypospadias. Methods Clinical data of 91 cases of hypospadias repaired in this hospital between 1997 and 2003 were retrospectively analyzed. Results Postoperative urethral fistula took place in 15 cases, with an overall incidence of 16 5% (15/91), including 6 cases treated by Duckett procedure, 4 cases treated by Duckett combined with Duplay procedure, 1 case treated by Mathieu procedure, 2 cases treated by scrotal island flap procedure (Onlay procedure), 1 case treated by Denis-Browne procedure, and 1 case treated by Snod-grass procedure. Conclusions For patients with hypospadias associated with serious chordee, because the urethral plate can not be preserved, adaptable methods should include scrotal island flap procedure, Duckett procedure, or Duckett procedure combined with Duplay procedure. Urethral plate conserving operations are suitable for hypospadias without chordee or with mild chordee, involving the Mathieu procedure, Onlay procedure, Snod-grass procedure and Denis-Browne procedure.

Objective To analysis the clinical and pathological features, results of laboratory tests and prognosis of nephrotic syndrome (NS) in patients with non-heamatological maligancy. Methods The data were collected from 25 patients who presented with NS around the diagnosis of non-heamatological malignancy. Results Twenty-five cases were investigated (age: (56.6±17.7) years; male/female ratio: 20/5). Malignancy and NS occurred within one year in 92% patients. There was a wide distribution of malignancy with involvement of 36% in digestive system and 20% in respiratory system. Ten patients (40%) presented with NS as their initial manifestation. Heamaturia appeared in 67% patients and acute renal insufficiency was complicated in 12% cases before treatments. Some other non-specific laboratory tests were found including elevated serum gamma-globulin in 50% and anemia not related with renal failure in 28% cases. Membranous nephropathy was the most common pathological changes in 67% cases. Although NS still continued for several weeks in 8 of 9 cases after surgery and/or chemical therapy, glucocorticoids was helpful to achieve the remission in these patients. However, no remission was achieved in patients without the treatment for malignancy. Conclusion Malignancy may present with NS as its initial manifestation. It should be inspected routinely and regularly in elder patients with NS, especially in those with membranous nephropathy, as well as gamma-globulinemia and anemia.

Objective To compare RNA interference (RNAi) with imatinib in killing K562 cells. Methods Design effective shRNA sequences special for bcr-abl silencing and insert them into the eukaryotic expression vector for RNAi by gene engineering. The recombinant plasmi(ts were then transfected into K562 cells. 48 hours later, the efficiency of transfection was identified by fluorescent microscope, bcr-abl mRNA level was detected by RT-PCR. Another group of K562 cells were treated respectively by imatinib with different concentration. All groups of K562 cells were finally analyzed in apoptosis, cell proliferation and phosphotyrosine-containing proteins. Results Both RNAi and imatinib induced apoptosis, decreased proliferation and reduced phosphotyrosine-containing proteins. Conclusion BNAi can kill K562 cells successfully as imatinib, and it may be a promising way to treat CML patients in clinic, especially for those who fail in imatinib or other chemotherapy.

Hepatic nodules in patients with Budd-Chiari syndrome (B-CS) are identified in clinical work and the differentiating diagnosis is very important for making the treatment strategy.Most B-CS patients with hepatic nodules have nonspecific clinical manifestations.Ultrasonography,computed tomography and magnetic resonance imaging are often used for differentiating diagnosis.According to the results of retrospective study on clinical and imaging data of 51 B-CS patients with hepatic nodules,we draw a conclusion that the differentiating diagnosis of hepatic nodules in patients with B-CS depends on imaging characteristics.Different treatment strategies are adopted according to the comprehensive analysis of these imaging data and satisfactory results can be achieved.

BACKGROUND: The expression of Fas antigen and P53 protein in colorectal cancer could reflect the biological character and the prognosis of the tumor.OBJECTIVE: To investigate the relationship between the expression of Fas antigen and P53 protein in coloreetal cancer and the tumor-related biological characters.DESIGN: A controlled experiment by introducing pathological specimens as subjects.SETTING: The study was conducted in the Department of Pathology of Xijing Hospital Affiliated with the Fourth Military Medical University of Chinese PLA.PARTICIPANT S: Totally 32 pathological specimens of colorectal cancer were randomly selected from the Department of Surgery of Xijing Hospital between January 1995 and October 1998. Sixteen normal large intestine tissues were selected form the cadaver of pathology department.METHODS: The expression of Fas antigen and P53 protein in 32 colorectal cancer tissue and 16 normal intestine tissue were tested and compared with immunohistochemical method.MAIN OUTCOME MEASURES: Fas antigen and P53 protein expression in coloreetal cancer and normal intestine, and the clinical indicators of patients with colorectal cancer.RESULTS: The expression of Fas antigen was positive in normal large intestine tissue while the expression of P53 protein was negative. The positive rate of Fas antigen expression in colorectal cancer was 41% (13/32), while the positive rate of P53 expression in colorectal caner was 53% (17/32). Fas antigen significantly decreased in colorectal cancer tissues. The expression of Fas antigen was correlated with the histological type of colorectal cancer and its liver metastasis( P ＜ 0.05) . And the expression of P53 protein was correlated with the liver metastasis of colorectal cancer( P ＜ 0. 05).CONCLUSION: The expression of Fas antigen significantly decreases in colorectal cancer. The higher the malignance is, the more significant less the expression is. Fas antigen does not express in liver metastasis patients. P53protein had positive expression in colorectal cancer tissues, especially in patients with liver metastasis. The reduction and deletion of Fas antigen expression and the excessive expression of P53 protein indicate poor prognosis.

Objective To explore the expression and clinical significance of constitutive androstane receptor(CAR)in placenta syntrophoblast from patients with intrahepatic cholestasis of pregnancy(ICP).Methods Placenta were collected from women with ICP who delivered from April 2009 to March 2010 in First Affiliated Hospital of Chongqing Medical University.According to the severity of ICP,patients were classified into mild ICP group(n=10)and severe ICP group(n=10).Ten healthy pregnant women who delivered in the same period were chosen as control group.The location of CAR protein in placenta was studied by immunohistochemical streptavidin-biotin complex(SABC)method.CAR mRNA level was determined by reverse transcription(RT)-PCR technique and CAR protein expression level was determined by western blot.Results(1)CAR was located in the placenta syncytiotrophoblastic cells in control group and mild ICP group,showed light tan when stained,and was mainly in the cytoplasm.In severe ICP group,CAR was also located in placenta syncytiotrophoblastic cells but mainly in the nucleolus,showed dark tan when stained.(2)The mRNA expressions of CAR in control group,mild ICP group,severe ICP group were 0.06 ±0.03,0.07 ±0.03 and 0.56±0.03.respectively.CAR in severe ICP group was significantly higher than those in control group and mild ICP group(P＜0.05).The difference of mRNA between control group and mild ICP group wag not statistically significant(P＞0.05).(3)The CAR protein levels in control group,mild ICP group,severe ICP group were 0.74±0.03,0.79±01 03 and 1.02±0.04,respectively.CAR protein expression in the severe ICP group was significantly higher than the other two groups(P＜0.05).And there was no statistical significance between mild group and control group(P＞0.05).Conclusion In ICP women.especially severe ICP patients,the CAR expression in placenta syncytiotrophoblastic cells increased appreciably,which may be involved in the maintenance of placenta barrier function and protection in ICP pathogenesis.
