OBJECTIVE:To explore the effect of Shugan jianpi formula on the proliferation and apoptosis of the hyperplastic tissues of mammary gland of model rats.METHODS:The rats were injected with benzestrofol and progesterone to establish mammoplasia model,meanwhile which were treated intragastrically with Shugan jianpi formula for 30 days.The degree of mammoplasia,as well as the PCNA(proliferating cell nuclear antigen),the apoptotic related regulating factors such as Bcl-2 and Bax and the apoptotic index(AI)of the mammary gland were detected.RESULTS:Shugan jianpi formula inhibited the mammoplasia,down-regulated the expression levels of PCNA and Bcl-2,up-regulated the expression level of Bax and AI,inhibited the proliferation of the mammary tissues and promoted apoptosis.CONCLUSION:Shugan jianpi formula blocks or reverses the hyperplasia of mammary gland by regulating the cell proliferation/apoptosis of the hyperplastic tissues of mammary gland.

Carbohydrate antigen-125 is a nonspecific tumor marker,which was used as an aid in the diagnosis and monitoring of patients with ovarian cancer in the past.But recent studies find that CA-125 in patients with liver disease also has different expression levels.In this article,we review the expression levels,related mechanisms and the significance of CA-125 in different liver disease.

OBJECTIVE:To investigate the therapeutic efficacy and safety of mycophenolate mofetil combined with glucocorti-coid in the treatment of refractory idiopathic thrombocytopenic purpura (ITP). METHODS:134 cases of refractory ITP were ran-domly divided into observation group and control group,with 67 cases in each group. Control group was given Prednison acetate tablet orally,0.5 mg/kg each day,morning and evening. Observation group was additionally given Mycophenolate mofetil dispers-ible tablet,1 g/time,bid. A treatment course lasted for 3 weeks,and both groups received 3-5 courses of treatment. Clinical effica-cy of 2 groups were compared as well as the change of PLT before and after treatment,satisfaction degree of treatment and adverse event. RESULTS:The total effective rate of observation group (91.04%) was significantly higher than that of control group (74.63%),with statistical significance(P<0.05);PLT of observation group was significantly greater than that of control group 7, 14 and 21 d after treatment,with statistical significance(P<0.05);total satisfactory degree of observation group was significantly higher than that of control group (89.55% vs. 80.60%),and the incidence of adverse event was significantly lower than control group(2.99% vs. 10.44%),with statistical significance(P<0.05). CONCLUSIONS:Mycophenolate mofetil combined with glu-cocorticoid can improve clinical efficacy,PLT and satisfactory degree significantly in the treatment of refractory ITP with good safety.

Pancreatic encephalopathy(PE)is one of the severe complications in acute pancreati-tis,which is characterized by a group of neurological signs and symptoms. Itˊs very difficult to have an early diagnosis,while the morality of PE is very high and the prognosis is very poor. Eliminating causes of pan-creatic encephalopathy,early diagnosis and combined therapy are the keys to achieve good curative effects. This paper reviewed the recent progress in the main mechanisms,clinical manifestations,diagnosis and therapy of PE.

Objective Summarize the lesion characters, procedure results and clinical follow up results of the elderly patients with coronary heart disease who underwent coronary angioplasty Methods 53 cases of coronary heart disease patients undergoing PTCA and stenting were ≥65 years old 35 were male, 18 were female 33 patients were diagnosed acute Q wave myocardial infarction, 2 patients acute non Q wave myocardial infarction, 14 patients unstable angina pectoris, and 4 patients coronary heart disease with severe heart failure PTCA and stenting were performed with conventional method, and temporary pacemakers were used if necessary Heparin was used if target vessel were involved in small vessels or the patients had multivessel diffuse lesions or PTCA was performed in more than one vessel Results Multivessel diffuse severe atherosclerosis was common in elderly patients The lesions were complex, and the procedures were difficult The success rate was 98% and the mortality was 11% during hospitalization 30 patients were follow up in 8 7?5 4 months, during which 11 (36%) patients had angina, 1 (3 5%) patients suffered acute myocardium infarction, 1 (3 5%) patient died of cerebral infarction, and the other 17 patients were asymptomatic Conclusion PTCA for the elderly patients is feasible The lesions in elderly patients with coronary heart disease are complex, the procedures are difficult and the mortality in hospitalization and the recurrent of ischemic chest pain are higher However, if we sufficiently estimate the lesion′s characters, PTCA can be safely performed in the elderly patients, and PTCA is the better method for elderly patients than medicine treatment

Objective To investigate the prevention and treatment mechanism of liver-smoothing and spleen-srengthening formula on hyperplasia of mammary gland,we study the effects of it on morphology,histology,serum sex hormone and its receptor of rats with hyperplasia of mammary gland.Methods Sixty female Wistar rats(SPF)were randomized into 5 groups:control group,disease model group,the tamoxifen group,small dose of medicine group and large-dose drug group.Estradiol Benzoate and Progesterone were used to establish animal model of breast hyperplasia.Rats in different groups were respectively maintained with Tamoxifen,small and large dose of liver-smoothing and spleen-srengthening formula.Then changes of morphology,histology,serum sex hormone and its receptor were obtained.Results Liver-smoothing and spleen-srengthening formula could reduce the number of breast lobular and the expansion degree of adenovirus catheter.It also narrowed the acinar cavity.In serum of rats with breast hyperplasia,Estradiol(E2)and PRL were declined ;Progesterone(P)and Testosterone(T)were increased;FSH and LH were partly increased.Positive expression degree of ER and PR were inhibited obviously.Conclusion Liver-smoothing and spleen-srengthening formula can reduce not only the content of estrogen receptors(ER)and progesterone receptors(PR)but also their sensitivity to estrogen of rats with breast hyperplasia by regulating the serum sex hormone.Our studies suggest that it can obviously inhibit hyperplasia of mammary gland.

Objective To describe the imaging appearances of mesenteric cavernous hemolymphangioma.Methods The ultrasonography(USG) and CT findings of 5 patients with mesenteric cavernous hemolymphangioma confirmed by operation and pathology were analyzed retrospectively.Results The tumors were reticulate hypoechoic masses on USG,the insides of them were of abundant red or blue blood flows signal on colour Doppler flow imaging(CDFI).On CT,the masses appeared as heterogeneous density with irregular margins and multiple round-like iso-or low dense cystoid foci with asymmetric thickness walls around the lesions.Conclusion The application of CT combined with USG may improve the diagnostic accuracy of mesenteric cavernous hemolymphangioma.

Objective To understand the trend of the constituent ratio of atrial fibrillation(AF)and primary etiology in hospitalized cases with chronic heart failure(CHF)and complicated with AF in late 20 years.Methods 1 180 patients with CHF(thereinto,440 complicated with AF)were selected from the hospitalized cases during the past 20 years(1983—2002),and a retrospective analysis was performed with every 5 years interval.Results The constituent ratio of AF in the general cases with CHF was 37.3%,and it was higher in females than in males(41.3% vs 33.4%,P

Objective To detect the mutations in RECQL4 gene in a Chinese patient with Rothmund- Thomson syndrome (RTS). Methods Blood samples were collected from a sporadic patient with RTS, his unaffected parents and 30 unrelated population-matched controls. DNA was extracted, and all the coding sequences of RECQL4 gene were amplified by PCR. Direct sequencing was performed with the amplicons to detect the possible mutations in these subjects. Results Two mutations, i.e., IVS11-1G > A and 3401 A >T, which resulted in a premature termination codon at amino acid 560, were found in the RECQL4 gene of the patient. His father was heterozygous for IVS11-1G > A, and his mother for 3401 A>T. Meanwhile, neither of the two mutations were observed in 30 unrelated normal control individuals. Conclusion Two mutations, including IVS11-1G>A and 3401 A>T are present in the RECQL4 gene of the sporadic patient with RTS.

Primary hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide.MicroRNAs (miRNAs) are a kind of endogenous non coding singlestranded RNAs,which can function as a tumor promoter or suppressor in the development and progression of human malignant tumors.Studies have shown that miRNAs play an important role in the occurrence and development of HCC.Numerous studies have found that the expression of miR-34a in various tumors is reduced and it participates in the carcinogenesis.Currently,the role of miR-34a in the tumorigenesis and development of HCC has attracted widespread attentions.Studies have confirmed that miR-34a can regulate the expression of its target genes and thus affect some key biological processes such as cell proliferation,apoptosis,invasion and metastasis of HCC.In this paper,we mainly reviewed the recent research progress on the role of miR34a in HCC.
