Objective To investigate the effects of Shen-fu injection on pulmonary contusion rabbits. Meth-ods Sixteen rabbits were randomly divided into 2 groups: the treatment group (Shen-fu group) and the control group. The animals were induced the pulmonary contusion models. After 60min, the animals in Shen-fu group re-ceived Shen-fu injection received 5 ml/kg, and those in control group 5 ml/kg LRS. The animals were killed six hours later, the right lung tissue wet-to-dry (W/D) ratio and myeloperoxidase (MPO) activity were obtained,the pro-tein expression of nuclear factor-kappa B (NF-κB) and intercellular adhesion molecule-1 (ICAM-1) were also detec-ted. Results The lung tissue W/D, MPO, and the protein expression of NF-κB and ICAM-1 were decreased evi-dently in Shen-fu group (P<0. 01). The morphologic and ultrastructural damages in Shen-fu group were milder than in control group. Conclusion Shen-fu injection is effective on pulmonary contusion rabbits.

Objective To determine the Golgi dispersal in radiation damaged cells and the protective effect of vanillin derivatives.Methods Immunofluorescence, cell cycle analysis of flow-cytometry,Western blot,and clone formation were used.Results Immunofluorescence observation showed that the Golgi dispersal caused by 2 Gy 60 Coγ-ray was significantly increased in a dose-dependent manner in the range of 4-10 Gy as was demonstrated by the fact that the Golgi area was significantly increased. When the irradiated cells were treated with the radioprotective agent VND3207, a vanillin derivative,the Golgi dispersal induced by radiation was significantly reduced.The radiation-induced Golgi dispersal was also displayed in a pattern of time-course after irradiation in the HeLa cells, and persisted at least to 36 h post-irradiation. Cell cycle test results indicated that the Golgi dispersal was not associated with the G2/M arrest triggered by radiation-induced DNA damage response.VND3207 could promote cell survival by plate colony formation assay.Conclusion The Golgi dispersal can be caused byγ-ray irradiation in a dose-and time-dependent manner, and VND3207 can provide a good protection against radiation injury associated with inhibited Golgi dispersal.

Objective To study the microstructural and ultrastructural changes of the epididymis of experimental varicocele in adolescent rats and it's role in infertility resulting from varicocele. Methods A varicocele model was performed in adolescent Sprague Dawley rats by partially ligating the left renal vein,the different segments of the epididymides of the rats were prepared for light and electron microscopy,the microstructure and ultrastructure of the epididymis were studied. Results There were lesions of different degree and segment specific changes in the epididymis with varicocele.Light microscopically,the main changes were interstitial vascular hyperemia,lymphocytes infiltration,sperm granuloma developed in the interstitial;The structure of the columnar epithelia was anomalies,epithelial cells degeneration,even the vacuoles appeared in the epithelial cells.The number of halo and clear cells increased.Inside the cavity of the duct,there were shedding cells,macrophage,deformed sperms and residual bodies.Electron microscopically,numerous large lysosomes,the residual bodies,the defected main cellular organelles(e.g. the endoplasmic reticulum,the mitochondrion and the Golgi complex etc.)and even large clear vacuoles were presented in the cytoplasm of principal cells.Clear cells were filled with lysosomes that made them frequently bulging into the lumen.The microvilli of the columnar epithelia were sparse and showed local defects.The thickness of the basal membrane increased.Conclusion\ The experimental varicocele in adolescent rats lead to microstructure and ultrastructure lesions in the epididymis,which may be another important reason of infertility resulting from varicocele.\;[

Objective To investigate the effectiveness of intermittent pneumatic compression (IPC) devices combined with anticoagulants for the prevention of deep vein thrombosis (DVT) after joint replacement surgery.Methods All of 400 patients were involved in this prospective randomized control study with 100 total knee arthroplasty (TKA) patients and 100 total hip arthroplasty (THA) patients in each group.All patients were operated under the general anesthesia.Patients in the control group received 10 mg of rivaroxaban per day beginning 6-8 hours after the surgery.Besides the prescription of rivaroxaban, IPC devices were used just after the anesthesia in the operating theater and lasted for 48 hours in the experimental group.The diagnosis of DVT in the lower extremities was made by color Duplex sonography on the second postoperative day.The incidence rate of DVT and symptomatic pulmonary embolism was recorded.The incidence rates of total DVT, proximal DVT (p-DVT, proximal to the trifurcation of the popliteal vein), distal DVT (d-DVT, in the anterior tibial vein, posterior tibial vein or peroneal vein) and intermuscular DVT were recorded.CT pulmonary angiography was used to confirm the pulmonary embolism if it was suspected.Results The incidence rates of overall, proximal, distal and intermuscular DVT were 9.5%, 0.5%, 0.5%, 8.5% in the experimental group and 30%, 0.5%, 5.5%, 24% in the control group respectively.The incidence rates of total DVT, distal DVT and intermuscular DVT were significantly lower in the experimental group.The incidence rate of DVT in TKA patients and THA patients were significantly lower in the experimental group than in the control group respectively.For patients with DVT, enoxaparin was used instead of rivaroxaban, and DVT was found disappeared by color Duplex sonography 10-12 days postoperatively.Conclusion Compared with the use of rivaroxaban alone, IPC devices combined with anticoagulants can significantly reduce the incidence rate of distal DVT and intermuscular DVT in the early postoperative period after joint replacement surgery.

SUMMARY To explore the clinical pathological characteristics and improve the recognition in the diag-nosis and treatment of basal cell carcinoma (BCC)of prostate.Three cases of BCC of prostate were re-ported and the relevant literature was reviewed to investigate the diagnosis and treatment of this disease. We analyzed three cases of prostatic BCC.Their ages were within a range of 57 to 83 years.One of them complained of hematuria and two complained of dysuria.All of them presented with prostatic hyperplasia. Two of them presented with high prostate specific antigen (PSA)and one with normal PSA.Case 1 had prostate cancer invasion of bladder,rectal fascia,with lymph node metastasis,bone metastasis and lung metastases.The patient received bladder resection +bilateral ureteral cutaneous ureterostomy +lymph node dissection on November 2,2014 .Postoperative pathological diagnosis showed BCC.Reexamination of pelvic enhanced MRI in January 8,2015 suggested pelvic recurrence.Abdominal enhanced CT showed multiple liver metastases and pancreatic metastasis on July 11,2015.Prostate cancer specific death occurred in October 2015.Case 2 was diagnosed as BCC in prostate biopsy on March 27,2015. Positron emission tomography and computed tomography (PET-CT)showed pulmonary metastasis and bone metastasis.Then the patient received chemotherapy,endocrine therapy and local radiation therapy. Reexamination of PET-CT on January 11,2016 showed that the lung metastase tumors and bone metas-tase tumors were larger than before.Up to January 10,2016,the patient was still alive.Postoperative pathological changes of transurethral resection of prostate (TURP)in case 3 showed BCC might be con-sidered.The PET-CT suggested residual prostate cancer,which might be associated with bilateral pelvic lymph node metastasis.In April 20,2016,the review of PET-CT showed pelvic huge irregular hybrid density shadow,about 14.5 cm ×10.0 cm ×12.9 cm in size,and tumor recurrence was considered. Then the patient received local radiation therapy.The patient survived in the followed upon January 10, 2016.BCC of prostate is a rare subtype.Due to the local infiltrative and distant metastatic potentiality, active management is preferred and a life-long follow-up is necessary.

Objective To discuss the application of spectral CT imaging in evaluating the early therapeutic response of 125I seed interstitial brachytherapy for pancreatic carcinoma in experimental nude mice.Methods BxPC-3 human pancreatic cancer cell xenografts were subcutaneously inoculated at the dorsal part of the limbs in 16 BABL/c nude mice. When the tumor developed to the size of 1-1.5 cm, the tumor-bearing mice were randomly divided into the study group (n=8,receiving implantation of 125I seeds of 1.0 mCi) and the control group (n=8,receiving implantation of ghost shell particles of 0 mCi). Two weeks after the procedure, plain spectral CT scan as well as enhanced multiphase (10 s, 25 s and 60 s) spectral CT scan were performed to obtain multi-phasic image series. The contrast-to-noise ratio (CNR) and iodine concentration (IC) inside the lesions were determined, and the normalized iodine concentrations (nIC) of tumor were thus obtained. Immunohistochemical staining of tumor was used to measure microvessel density (MVD) within the tumor;the correlation between nIC and MVD was analyzed. Results The lesion's nICs measured on each of three phases (10 s,25 s and 60 s) in the study group were lower than those in the control group, the differences were statistically significant (P<0.05). MVD count in the study group was lower than that in the control group, the difference was statistically significant (t=5.957,P<0.01). A parallel linear correlation existed between nIC obtained from each phase of three phases and MVD count (r=0.63,P<0.000 1;r=0.51,P=0.002;and r=0.48,P=0.001 7 for 10 s, 25 s and 60 s phases respectively). Conclusion Spectral CT imaging is an effective method for evaluating the therapeutic effect of 125I seed interstitial brachytherapy for pancreatic carcinoma of experimental mice.

OBJECTIVETo investigate the development of xenografted primitive human germ cells by using fetal testicular tissues as donor tissues and an immunodeficient mouse as the recipient.
METHODSTesticular tissue fragments of a 26-week fetus were grafted under the back skin of a castrated immunodeficient mouse. Grafts were taken out after 135 days and processed for morphological and histological analyses.
RESULTSThe mass of grafts grew from about 1 mm in diameter and 5 mg in wet weight to about 3 mm and more than 20 mg 135 days after grafting. Histological observations showed a significant expansion of seminiferous tubules after grafting (80 +/- 25 microm in diameter) in comparison with seminiferous cords at the time of grafting (60 +/- 15 microm in diameter). The seminiferous cords developed into seminiferous tubules with the epithelial border and lumen. After 135 days of grafting, most of the dispersedly distributed primitive Sertoli cells and germ cells migrated to the basal part of seminiferous epithelium, located on the basement membrane and few of germ cells differentiated into spermatogonia.
CONCLUSIONHuman fetal testicular tissues could survive and continuously develop after being xenograft into castrated immunodeficient mice.
