Objective To study the clinical, histological and immunohistochemical features of breast hamartomas. Methods The specimens were fixed in 10% formalin and embedded in paraffin. The sections were stained with hematoxylin and eosin for histological diagnosis. SP technique was used in the immunohistochemical study.Results We have 8 cases of breast hamartomas with well defined borders microscopically, histologically composed of ducts, lobules, fibrous stroma, adipose tissue. None of the epithelial elements showed any evidence of atypia. Immunohistochemical analysis showed that there was a variable number of epithelial cells showing a nuclear staining for estrogen receptor(ER) in all cases.Conclution Mammary hamartomas are benign tumor like lesions, histologically dissimillar from other breast tumors. It is affected by hormonal factors. The diagnosis is achieved by combining clinical, radiological and pathologic results.

Objective To investigated the efficacy and toxic effects of combined chemotherapy of vinorelbine plus cisplatin or carboplatin in patients aged ≥ 70 years and with non-small cell lung cancer (NSCLC).Methods One hundred patients with lung cancer aged ≥70 years were enrolled in the study.Fifty patients in chemotherapy group were assigned to receive vinorelbine 25 mg/m2 at the first day and the fifth day plus cisplatin 60-70 mg/m2 or carboplatin 250 mg/m2 at the second day.All treatments were repeated every 3 or 4 weeks.Another fifty patients aged ≥ 70 years were taken as control group, not receiving treatment.The primary endpoint was survival.Results Forty-five patients were evaluable for response and the partial remission rate was 35.6% (16/45).One year survival rate was 37.8% and median survival time was 9.75 months in chemotherapy group.The median survival time was 4.0 months for patients in control group.All 50 patients in chemotherapy group were evaluable for toxic side effects.WHO grade Ⅲ incidences of leucopoenia, neutropenia and anemia were 38.0%, 52.0% and 2.2%, respectively.Grade IV incidence of neutropenia was 35.5%.WHO grade Ⅲ incidences of fatigue, constipation and vomit were 22.0%, 8.0% and 14.8%,respectively.Five patients failed to complete the treatment due to side effects.Conclusions Combined chemotherapy of vinorelbine plus platinum drugs is effective and tolerated in patients aged over 70 years with advanced NSCLC.Even patients with stable clinical effects shows benefit of survival time.

Renalase, a novel amine oxidase, is secreted by kidney. It regulates heart function and blood pressure by degrading catecholamines. Hormones secreted by the kidney are associated with cardiovascular disease. Renalase, as a new biomarker of heart and kidney functional correlation, can lower blood pressure, protect ischemic heart muscle, improve heart function and degrade catecholamine.

Objective To detect the blood parameter, blood biochemical and electrolyte indices of the F1 generation of Rongshui miniature pig ( RMP) .Methods The blood of 43 female and 42 male RMPs of 4 th month old, and 36 RMPs of 12th month old ( half male and female) were extracted from jugular vein.And the blood parameter, blood biochemical and electrolyte indices were detected by blood analyzer and automatic biochemical analyzer.Results In the same month-old RMP, no significant difference between male and female were found in most indices of blood parameter, blood biochemical and electrolyte indices.On the other hand, many indices were difference between 4th month old and 12th month old RMPs of same gender.Compared with the 4th month old RMP, the 12th month old RMP decreased significantly in WBC and PLT, increased in HGB ( P <0.05 ) while RBC was the same ( P >0.05 ) .Serum ALT, AST, ALP, CK (male), LDH(male), A/G, BUN, GLU (female), CHOL (male) and K+decreased significantly (P <0.05), while serum TP, TBIL, CR and Ca2+increased significantly (P <0.05),but serum CHOL, TG, HDL-C and LDL-C were not different.86.4%(19/22) biochemical and electrolyte indices in RMP were in/or close to the range of normal value of human.Conclusion Most of the blood parameter, blood biochemical and electrolyte indices of RMP were close to human’ s normal value.

OBJECTIVE: To comprehend the epidemiological status and risk factors in hypertensive disorder complicating pregnancy (HDCP) in a district in Changsha, and to provide epidemiological evidence for early intervention of HDCP. METHODS: A total of 2 148 pregnant women in a district in Changsha from 2008 to 2009 were retrospectively analyzed and the related factors were evaluated by multivariate unconditional logistic analysis. RESULTS: The incidence of HDCP was 5.21% from 2008 to 2009. Multivariate unconditional logistic regression analysis showed that age (>35 years old)(OR=6.440,95%CI:2.987-13.884), body mass index (BMI) before pregnancy (OR=2.180,95%CI:1.619-2.936), and history of diabetes or kidney disease (OR=14.221,95%CI: 3.990-50.684) were risk factors for HDCP. CONCLUSION Age, BMI before pregnancy, and history of diabetes or kidney disease are risk factors for HDCP, while gravidity, parity, number of abortion and multiple gestation pregnancy have no obvious correlation with HDCP.

OBJECTIVE: To investigate the impact of renal denervation on the blood pressure, plasma renalase content and expression of renalase and tyrosine hydroxylase (TH) in the idney of spontaneous hypertensive (SH) rats and to explore the role of renal denervation in lowering the blood pressure. METHODS: SH rats were randomly assigned into a baseline group, a surgery (renal denervation) group, a sham group and a control group (n=48). WKY rats matched in age (n=12) served as a baseline control group. All rats were housed until 12 weeks old. Then, the rats in the baseline group and the WKY group were sacrificed whose blood and kidney were collected for examination. In the renal denervation group, the sham group and the control group, the blood pressure was monitored continuously. One week and 6 weeks after the renal denervation, 6 rats in each group were sacrificed whose blood and kidney were collected. ELISA was employed to measure the plasma renalase and Western blot assay done to detect the expression of TH and renalase in the kidney. RESULTS: Compared with WKY rats, blood pressure significantly increased and TH protein expression markedly elevated (P<0.05) in SH rats in the baseline group, but plasma renalase content and protein expression of renalase in the kidney dramatically reduced (P<0.05). One week after the surgery, the mean arterial pressure and TH protein expression in the surgery group were lowered compared with the baseline group and dramatically reduced compared with the sham group and the control group (P<0.05). In the surgery group, the renalase level was markedly increased compared with the baseline group, the sham group, and the control group (P<0.05). Six weeks after the renal denervation, the mean arterial pressure and TH level in the surgery group were significantly increased but the renalase content and expression markedly reduced compared with those 1 week, but there were no marked differences among the surgery group, the sham group, and the control group (P>0.05). No pronounced differences in the above variables were found between the sham group and the control group at any time point (P>0.05). CONCLUSION Renal denervation can lower the blood pressure, which may attribute to the suppression of sympathetic nerves, increase in plasma renalase content and renalase expression in the kidney.

BACKGROUNDUroacitides is a group of cell differentiation inducers, which is purified from fresh human urine. Preclinical studies of Uroacitides have showed that cancer cells could be induced to differentiate, and the growth of cancer cells could be inhibited by Uroacitides. The aim of this study is to compare the efficacy and toxicity between Uroacitides combined with NP regimen and NP alone in treatment of advanced non-small cell lung cancer (NSCLC).

METHODSForty-two cases of advanced NSCLC were randomized into Uroacitides+NP and NP groups. NP group: NVB 25mg/m² on days 1 and 8, DDP 75mg/m² on day 1. Uroacitides combined with NP group: Uroacitides of 300mL was given through subclavian catheter daily for 7 days prior to the NP chemotherapy, then concurrently with NP regimen for 2 cycles, except the days of administration of chemotherapy.

RESULTSIn the Uroacitides+NP group, the overall response rate was 44.4%, and 20.0% in the NP group (P > 0.05). The median survival time was 9 months in the Uroacitides+NP group and 6 months in the NP group (P=0.0287). The main toxicities were myelosuppression, gastrointestinal reaction and alopecia, and there was no significant difference in incidences of toxicities between the two groups (P > 0.05).

CONCLUSIONSUroacitides combined with NP regimen shows a good curative effect and low toxicity, and may significantly prolong the median survival time for advanced NSCLC.

BACKGROUNDTo evaluate the efficacy, side-effects, median survival duration and survival rate of vinorelbine (NVB) combined with cisplatin (DDP) in the treatment of non-small cell lung cancer (NSCLC).

METHODSA total of 220 patients with inoperable NSCLC received NVB and DDP combined chemotherapy: NVB 25-30 mg/(m²*d) on days 1 and 5 (or 8), DDP 60-80 mg/(m²*d) on day 2. The schedule was repeated every 28 days. The efficacy and side-effects were analysed and followed-up after at least two cycles of chemotherapy.

RESULTSThe overall response rate (CR+PR) was 30.9% (68/220). The response rate was 31.3% (51/163) in initial treatment group, and 29.8% (17/57) in retreatment group. The median survival duration was 8.3 months. The 1-, 2- and 3-year survival rates were 39.23%, 19.31% and 6.32%, respectively. The main side-effects were myelosuppression and digestive tract reactions.

CONCLUSIONSVinorelbine plus cisplatin is an effective and well-tolerated regimen for non small cell lung cancer and myelosuppression is its dose-limiting toxicity.

OBJECTIVES: To investigate the effet of nasal septum operation combined with nasal sinuses on postoperative nasal septum. METHOD: Sixty-five patients with deflection of nasal septum complicating chronic sinusitis were underwent nasal septum and nasal sinus operations under nasal endoscope. Postoperative nasal septum recover were observed and compared with patients underwent only simple nasal septum operation. RESULT: Patients underwent nasal septum operations combined with nasal sinus, postoperative symptoms were more serious at early than simple nasal septum operations. At 3 months after operation, satisfactory degree of the former group were higher than the latter, and the former group didn't have complications such as nasal septum infection. CONCLUSION Nasal septum operations combined with nasal sinus have no harmful effect on the prognosis of nasal septum, so it was safe and reliable.
