Objective To investigate the diagnostic and therapeutic experience in children with ulcerative colitis(UC) from clinical data.Met-hods The literature on UC in children publicated from 1995 to 2004 were retrieved by CBM,CNKI and VIP database.The clinical manifestations,X-ray,endoscopic and histologic features,management and prognosis of 172 patients in this hospital correspond with the inclusion criteria were retrospectively investigated and a definite diagnosis with UC was made.Results Of 172 patients,the ratio of maleold female was 1.07:1.0,and the age of patients ranged from 2 months to 15 years old.Thirty-six patients(36.7%)were less than 3 years-old;the course ranged from 3 days to 4 years.One patient had family history.The main manifestations were chronic diarrhea,mucus bloody stool,bloody purulent stool and abdominal pain.The systemic symptoms were fever,weight loss,malnutrition and anemia,no enteral symptoms and complications.The lesions were mainly seen in the whole colon with moderate to severe degree.The therapies based on salicylaxosulfapyridine(SASP) or 5-acetylsalicylic acid(5-ASA) together with corticosteroid in the short period have clinical remission in different levels.From long follow-up,the complete remittence was less than one third.Conclusions It is not rare to see UC in infantile.The clinical characteristics of UC in children are different from those in adults,the same is true before and after 3 year-old.The UC in children has high misdiagnosis and is difficult to manage.It is very necessary to establish a diagnostic and therapeutic guideline for children with UC in China.

Objctive To search for the therapeutic method of children's nephrotic syndrome.Methods Sixty-six cases oe children's nephrotic syndrome were randomly divided into 2 groups,impulsion group (34 cases) and control group (32 cases). Dexamethasone (1．5~3 )/mg (kg?d) added into (100~150)ml 10%GS solution, intravenous drip in impulsion group, one time a day, totat 3 days, the fourth day stoped. The fifth day started again and used one time evcry two days, total 6 times. Prednisone(1．5~3)mg/(kg?d) were taken next day and total 4 weeks, then grandually decreased the dose. Only prodnisone was used in control group, the method and dose were the same as impulsion group.Results Complete remission. partial remission inefficacy ere 23, 7 and 4 cases respectiye1y in impulsion group and 22, 5 and 5 cases respectively in control group, the effective rates of the 2 group are 88．23%and 84．38% (P＞0．05). The times of state of illness stabilization are respectively 11．3?7．2 and 10．48?6．34 months in the 2 groups. The side effect of impulsion group is bigger than that of control group.Conclusion Children's primary nephrotic syndrome should be treated for 8 weeks by routine hormone induction therapy, if no remission, impulsion therapy could be used.

OBJECTIVETo study mRNA and protein expression of HOXA5 gene in breast carcinoma, to correlate the expression of HOXA5 gene with clinicopathologic parameters and to explore the possible role of HOXA5 gene in carcinogenesis, progression and metastasis of breast carcinoma.

METHODSTaqMan real-time reverse transcriptase-polymerase chain reaction (RT-PCR) was applied on 60 cases of primary breast carcinoma and 24 cases of benign mammary lesions in order to detect mRNA expression of HOXA5 gene. Immunohistochemical study using polyclonal antibody against HOXA5 was also performed. Statistical analysis was carried out to analyze the correlation between HOXA5 gene expression and various clinical parameters in these breast cancer patients.

RESULTS(1) The relative expression level of HOXA5 mRNA ranged from 0.73 to 193.07 (average = 20.85) in primary breast carcinoma, in contrast to 5.42 to 81.91 (average = 30.94) in benign mammary lesions. Compared with benign mammary lesions, a significant reduction in expression of HOXA5 mRNA was noted in primary breast carcinoma (P < 0.01). (2) There was a decreased or completely diminished HOXA5 protein expression in breast carcinoma. (3) HOXA5 mRNA expression was significantly lower in lymph node-positive cases, when compared with that in lymph node-negative cases (P < 0.05). A significant difference of HOXA5 protein expression was also observed in both groups (P < 0.01). Immunohistochemical staining of HOXA5 was either negative or weakly positive in lymph node-positive cases. On the other hand, moderately or strongly positive HOXA5 staining was noted in lymph node-negative cases. (4) Neither mRNA nor protein expression of HOXA5 gene correlated with clinicopathologic parameters such as age of patients, size of tumor, clinical stage, pathologic subtype or histologic grade (P > 0.05).

CONCLUSIONSDisordered expression of HOXA5 gene may play a role in the carcinogenesis of breast cancer. Reduced expression of HOXA5 gene may be related to the metastatic potential of breast carcinoma cells.

Forest musk deer (Moschus berezovskii), a rare wild medicinal animal, is listed under the category of the state key protected wildlife list of China. Musk, secreted by the musk glands, is with high economic and medicinal value and used as precious traditional medicine in China. In order to meet the needs of musk in Chinese traditional medicine, forest musk deer farming was conducted in 1950s, but the research progress on musk secretion mechanism was slow. Therefore, by reviewing the histological and anatomical structure of forest musk deer musk gland, the relationship between sex hormones and the musk secretion process, and the molecular mechanism of the musk secretion, the existing problems in investigating the musk secretion mechanism were analyzed and the development trends in this field were also discussed, in order to provide a reference for further studies on the musk secretion mechanism and improve musk production of forest musk deer.

Objective To investigate the renal pelvic pressure(RPP) during minimally invasivepereutaneous nephrolithotomy(MPCNL),and inspect its influence to postoperative fever. MethodsThe RPP was measured by baroeeptor,and these data about pressure and postoperative fever wereevaluated statistically. Results The mean RPP was 14.72 mm Hg,the mean accumulative time of RPP≥30 mm Hg was 116.06 s. Fifteen cases(18. 75%)had a postoperative fever. Logistical analysissuggested that postoperative fever did not correlate to sex(P=0.195),age(P=0.641),urinary tractinfection (P=0.663),white blood cell≥10 × 109/L in blood routine examination postoperatively (P=0.751),once an occurrence of RPP≥40 mm Hg(P=0.662),while infection calculi (P=0.000),percutaneous tract size(P=0.029),mean RPP(P=0.036) ,mean RPP≥20 mm Hg(P=0.013),accumulative time of RPP≥30 mm Hg(P=0.010) and RPP≥30 mm Hg longer than 50 s(P=0.024)contributed to postoperative fever. Conclusions Renal pelvic pressure generally remains lower than alevel to back flow (30 mm Hg) during MPCNL. A transient renal pelvic pressure≥30 mm Hg don'tcountribute to postoperative fever,while a temporary high pressure status(50 s)would had an accumulated effect which means an enough back flow to bring a fever.
