Purpose To explore the clinicopathological characteristics of primary non-Hodgkin lymphoma ( PNHL) of lung. Methods The clinical features, morphology and immunohistopathological phenotypes were retrospectively studied in 28 cases of PNHL and re-viewed of the literature. Results The composition of this group of cases is 18 cases of male, 10 cases female. The a median age of pa-tients was 57 years old. According to the WHO classification, all of the 28 cases of in our PNHL series were diagnosed as non-Hodgkin lymphoma ( NHL) , including 17 mucosa-associated lymphoid tissue extranodal marginal zone lymphomas ( MALT) , 5 diffuse large B cell lymphomas ( DLBLC) , 2 NK/T cell lymphomas and 2 anaplastic large cell lymphomas, 1 mantle cell lymphoma ( MCL) and 1 pe-ripheral T cell lymphomas, unspecified, respectively. One-third PNHL patients presented with specific clinical symptoms such as cough, chest pain, dyspnea, and fatigue, Imaging examination showed unilateral or bilateral pulmonary infiltrate, single lesions or multiple nodules, and the lesions always involved with the trachea, bronchus and lung. Follow-up was completed in 16 patients ( range, 3 to 38 months) . 3 cases were conducted with pneumonectomy, among which 2 cases were given postoperative adjuvant chem-otherapy. Seven patients were given chemotherapy alone, and 5 patients did not give any treatment following initial diagnosis. At the time of last follow-up, 13 patients were alive with disease, 2 patients were died. The tumor metastasis in the left inguinal lymph node was found in one patient after 2 years by surgery. Conclusions It was shown that there was no specific clinical manifestations and fea-tures of pulmonary PNHL. Among of them, the MALT is the most common diseases, and the highly aggressive lymphomas many be oc-cur, such as the DLBLC, NK/T cell lymphoma. The diagnosis of PNHL depends on pathological examination. The immunohistochemi-cal staining and molecular pathological technology may helpful for the diagnosis and differential diagnosis of the tumors.

Currently,there is a worldwide increase in the incidence and mortality of intrahepatic cholangiocarcinoma (ICC),but the etiology of ICC remains unclear.Recent efforts suggest an etiological role of hepatitis B virus (HBV)infection in ICC,and this article reviews the relationship between chronic HBV infection and the risk and prognosis of ICC.

BACKGROUND:Bone loss to different degrees may appear within 1 year after hip replacement in the femoral or acetabular sides, and severely affect long-term stability of the prosthesis and bone strength. Thus, to reduce bone loss around the prosthesis stem after total hip replacement is significant to prolong the use time of the prosthesis and to prevent fractures surrounding the prosthesis.
OBJECTIVE:To observe the preventive effect of zoledronic acid on bone loss surrounding the prosthesis stem after hip replacement.
METHODS:A total of 80 patients after total hip replacement in the People’s Hospital of Shenxian from February 2011 to September 2014 were enrol ed in this study. They were divided into two groups (n=40). At 4 days after replacement, patients in the observation group received treatment with zoledronic acid, but those in the control group did not give zoledronic acid. The rest medication was identical between the two groups. Bone mineral density in the hip was measured before replacement and at 1 year after replacement in both groups. Serum calcium and
phosphorus levels and alkaline phosphatase activities were observed before replacement, 3 days and 1 year after medication in the two groups. Adverse reaction during medication was recorded in the observation group.
RESULTS AND CONCLUSION:The average bone mineral density was significantly decreased in both groups at 1 year after replacement, and significant differences were found as compared with before replacement (P<0.05). The average bone mineral density was significantly higher in the observation group than in the control group at 1 year after
replacement (P<0.05). Calcium and phosphorus levels were significantly diminished at 3 days after medication as compared with that before replacement (P<0.05). Calcium and phosphorus levels maintained at the level before replacement at 1 year after medication. Alkaline phosphatase activities were slightly reduced within a short time after replacement in both groups, but no significant difference was found as compared with before replacement (P>0.05). Alkaline phosphatase activities were low in the observation group at 1 year after medication, and significant difference was detected as compared with the control group and that before replacement (P<0.05). No significant difference in alkaline phosphatase activities was detectable in the control group between 1-year post medication and pre-replacement (P>0.05). Within two or three days after medication, nine patients suffered from varying degrees of muscle aches and fever in the observation group, and above symptoms were lessened after taking acetaminophen. These results verify that after total hip replacement, zoledronic acid injection can effectively prevent bone loss around the prosthesis in early stage after replacement, but fever symptoms may occur within a week after replacement. Thus, it is recommended that zoledronic acid injection can be given at 1 week after replacement. If fever and other symptoms appear, acetaminophen can be given.

Peroxisomes (microbodies) were studied with CATase, G-6-Pase, TPPase, CMPase cytochemistry and stereology by electron microscopy in 15 cases of normal human liver specimens. In human hepatocytes peroxisomes are ellipsoid or round intracellular bodies. They contain homogeneous fine granular matrix, and surrounded by unit membrane, and distribute randomly in the cytoplasm. By stereological analysis, the peroxisomes accounted for 1.33?0.38% of the cytoplasmic volume, their numerical density in spase was 9.76?1.63/100 ?m~3 cytoplasm, and the ratio of mitochondria to peroxisomes in quantity was 6.22?1.17. The result of G-6-Pase cytochemistry showed no luminal connection between endoplasmic reticulum and peroxisomes. The membrane similar to smooth endoplasmic reticulum seem to be connected with peroxisomes which was G-6-Pase negative, hence such membrane may be peroxisomal membrane system rather than smooth endoplasmic reticulum. The TPPase cytochemistry showed that peroxisomes did not connect with the Golgi complex structurally, and the Golgi complex may not be involved in the biogenesis of peroxisomes. Some figures resembled fission and budding of peroxisomes were viewed, and this finding suggested that new peroxisomes formed probably by division of preexisting peroxisomes.

The human atrial muscle cells were investigated by ultrastructural CMPase cytochemistry and atrial natriuretic factor (ANF) immunocytochemistry. The primary lysosomes and ANF were labelled by these techniques, respectively. ANF was localized in the atrial specific granules, these granules were similar in size and 0.20? 0.051?m in diameter, distributed over the entire cytoplasm, preferentially being located in the subsarcolemmal and perinuclear region and forming clusters. Primary lysosomes were various in size, 0.30?0.191?m in diameter, significantly larger than atrial specific granules (P

Objective: To analyze the clinicopathological characteristics of differentiated thyroid carcinoma. Methods: We retrospectively analyzed 257 cases of differentiated thyroid carcinoma between 1996 and 2005 according to the WHO classification,together with the follow-up data of some of the cases.Results: The 257 cases of differentiated thyroid carcinoma constituted 15.3% of the 1681 cases of thyroid lesion and 93.1% of the 276 cases of malignant thyroid tumor detected in the same period,including 241 cases of papillary carcinoma(14.3% of the thyroid lesions and 87.3% of the malignant thyroid tumors) and 16 cases of follicular carcinoma(1.0% of the thyroid lesions and 5.8% of the malignant thyroid tumors).The male to female ratio was about 1∶2.7.Histologically,the papillary structure was frequently noted admixed with the follicular pattern.Papillary carcinoma of the thyroid complicated by Hashimoto's thyroiditis,follicular adenoma and nodular goiter accounted for 16.2%,11.6% and 14.9%,respectively.A 1-10 y follow-up of 97 patients showed that all but one survived.Conclusion: Differentiated thyroid carcinoma is a fairly common malignant tumor,with papillary carcinoma as the commonest histological type and some complicated by other thyroid diseases.Its prognosis is relatively good despite the common occurrence of lymphoid and lung metastasis and local invasion.
