International Journal of Pediatrics 2016;43(4):317-321
Objective To explore the effects of prenatal infection on the development of lungs by dynamic observation of morphology and numbers of inflammatory cells in lungs of rat pups exposed to antenatal inflammation.Methods Pregnant Wistar rats were randomly divided into experimental group and control group.Pregnant rats of both groups were intraperitoneal injected with either lipopolysaccharide (LPS) 2.5mg/kg or the same volume of normal saline on embryonic day 19 and 20, respectively, and were allowed to term deliver.Onday1, 3, 7, 14, 21and28 (D1, D3, D7, D14, D21 andD28), eight pups of each group were killed by 10% chloral hydrate (1ml/kg) and lungs were collected.The numbers of myeloperoxidase (MPO) and CD68 as markers of both neutrophils and macrophages were counted.Morphometric assessments were performed by measuring the mean numbers of alveolar, the mean ratio of alveolar surface area to per tissue and the mean thickness of alveolar septum.Results With the increasing of postnatal days, the mean numbers of alveolar and the mean ratio of alveolar surface area to per tissue in both groups increased.The mean thickness of alveolar septum got thinner and the numbers of inflammatory cells decreased.On D1, D3, D7 and D14, the mean alveolar numbers of the experimental group (88, 89, 102 and 127 /mm2) were significantly less than those of the control group (105, 109, 123, 156/mm2), P =0.024, 0.009, 0.013, 0.004, respectively.On D1, D3 and D7, the mean ratios of alveolar surface area to per tissue were significantly larger (0.552,0.603 and0.533) than those of control group (0.478, 0.485 and 0.404), P=0.003, 0.001, 0.000, respectively.On D1 and D3, the alveolar septum thickness was significantly thinner (12.30 and 10.75 μm) thanthatin control group (17.13 and 16.13 μm), P=0.000, 0.000, respectively.On D1, D3, D7 and D14, the mean numbers of neutrophils of the experimental group (681, 582, 393 and 379/mm2) were significantly more than those of control group (164, 211, 145 and 179 /mm2), P =0.000, 0.000, 0.000,0.003, respectively.On D1, D3 and D7, the mean numbers of macrophages (613, 578 and 337 /mm2)were significantly more than those of control group (170, 182 and 127, /mm2) , P=0.000, 0.000, 0.000,respectively.Conclusion Prenatal infection results in larger and fewer alveolars and more inflammatory cells in lungs of rat pups.With the increasing of postnatal days, the alveolar morphology was similar to the controis.

OBJECTIVE:To explore the effects of alendronate sodium on bone mineral density (BMD) and bone marker in prostate cancer elderly patients after medical castration therapy. METHODS:In perspective study,84 elderly patients undergoing medical castration therapy were selected and divided into treatment group(45 cases)and control group(39 cases)according to ran-dom number table. Control group received medical castration therapy+Calcium carbonate D3 tablets,1 tablet,po,qn;treatment group was additionally given Alendronate sodium tablets 70 mg,po,once a week,1 week after routine treatment,on the basis of control group. Treatment course of 2 groups lasted for 12 months. The levels of 25-OH-D,testosterone,BMD and bone marker were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:3 cases of treatment group and 1 case of control group dropped out of the study. Before treatment,there was no statistical significance in above indexes between 2 groups (P>0.05). After treatment,25-OH-D levels of 2 groups were increased slightly,but there was no statistical significance(P>0.05);tes-tosterone level of 2 groups were decreased significantly compared to before treatment,with statistical significance (P<0.05). 12 months after treatment,BMD of lumbar vertebra,collum femoris and hip were increased significantly in treatment group,while those were decreased significantly in control group;there was statistical significance in above indexes between 2 groups(P<0.05). The levels of N-terminal midfragment of osteocalcin,procollagen Ⅰ N-terminal propeptide and β-crosslaps were decreased signifi-cantly in treatment group,while those were increased significantly in control group;there was statistical significance in above in-dexes between 2 groups (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Alendronate sodium can prevent bone loss and reduce the rate of bone turnover in elderly patients with prostate cancer receiving medical castration therapy.

Objective To explore the clinical features of pulmonary tuberculosis complicated with DM and related factors. Method The manifestations of 87 newly diagnosed PTB patients with type 2 DM(DM-PTB group) at two hospitals in Tianjin during October 2003 to October 2004 were compared to 88 PTB patients without DM who were randomly choosen from the same hosipital.The factors related to sputum-positive TB or cavity were explored through unconditional logistic regression model. Results DM-PTB patients showed significanly lower frequencies of cough(66.7% vs 83.0%),toxicity symptoms(37.9% vs 62.5%) and haemoptysis(16.1% vs 33.0%) than those of PTB group.Positive-sputum(63.2% vs 34.1%),cavity(56.3% vs 13.6%),wide lesions and bilateral lesions on chest radiographs was more common in DM-PTB group than in PTB one.Introversion(OR=1.582, 95%CI:1.063 ~2.355),type 2 DM(OR =2.186,95% CI:1.082 ~4.420)and cavity(OR =2.793,95% CI:1.308 ~5.964)were factors independently associated with positive-sputum TB.The factors related to cavity included diabetes(OR=14.199,95%CI:5.376~ 37.501),cough,postive sputum and lore-up lobe lesion.Conclusion This study confirmed that clinical manifestations and chest radiographs of PTB patients complicated with type 2 DM significantly departed from the typical presentation.Type 2 DM seems to have a negative effect on postive-sputum and cavity.So it should be alarmed that DM-PTB patients who tend to have untypical clinical symptom and higher rate of positive sputum become the reservoirs of infection to cause the transmission of TB.
