Objective To explore the efficacy and safety of glucocorticoids+cyclophosphamide+tacrolimus capsules (GC+CTX+FK506) in the treatment of patients with type Ⅲ+V and Ⅳ+Vlupus nephritis. Methods The 31 cases with first diagnosis as systemic lupus erythematosus (SLE) with type Ⅲ+V and Ⅳ+Vlupus nephritis (LN) were selected, then divided into group A (CTX+GC) with 16 cases and group B (FK506+CTX+GC) with 15 cases. The group A received CTX+GC during treatment, group B received GC+CTX+FK506 for the first three months, and received FK506+GC for the last three months. The patients were followed up once monthly to observe the efficacy and safety,the efficacy was analysed after 6 months. Results After treatment, the total efficacy in group B was significantly higher than group A (86.7%vs.50.0%, P<0.05). The 24 h urine protein of group B was lower than group A(P<0.05). The plasma albumin of group B was higher than group A (P<0.05). After treatment, the systemic lupus erythematosus disease activity index (SLEDAI) in two groups were lower and C3 level was higher than those pre-treatment(P<0.05), but there was no significant difference in above indicators between two groups. There was one case menelipsis in group A, and one case with transient increasing of creatinine. Conclusion The FK506+CTX+GC could reduce urine protein sifnificantly compared with CTX+GC without serious adverse reaction.

Objective To investigate the expression of bone sialoprotein (BSP) in prostate cancer and its clinical significance. Methods Prostate cancer tissues of different pathological grades (68 cases) and benign prostatic hyperplasia tissues (22 cases) were selected. SP method was used to detect the expression of BSP. Serum total prostate-specific antigen (tPSA) levels of prostate cancer were detected by electrochemiluminescence immunoassay before the operation. Results Compared with no or low expression in the adjacent normal glandular tissues, the detectable levels of BSP were examined in most of the prostate cancer tissues. The expression rate of BSP in prostate cancer tissues was higher than that in benign prostatic hyperplasia tissues [76.47%(52/68) vs 13.64%(3/22),χ2=27.614, P<0.001]. The expression rates of BSP in well differentiated, moderately differentiated and poorly differentiated tissues according to cell differentiating degree (Gleason system) were 75.0 % (12/16), 77.5 % (31/40) and 75.0 % (9/12) respectively. There was no significant difference in various pathological grading (χ2=0.057, P=0.972). The expression rates of BSP in pathological stage pT2, pT3 and pT4 tissues were 62.16%(23/37), 95.24%(20/21) and 90.0%(9/10) respectively. A statistically significant association was found between BSP expression and pathological stage (χ2=9.338, P=0.009). Serum tPSA level of prostate cancer group with BSP expression was higher than that with no BSP expression [(69.06±25.52)μg/L vs (38.00±21.64)μg/L, F=19.355, P<0.001]. Conclusion The high expression of BSP in prostate cancer has a relationship with pathological stage and serum tPSA level, it may play an important role in the biological behaviour of prostate cancer.

Objective:To observe the effect of early goal directed sedation (EGDS) on cerebral oxygen metabolism in patients with acute brain injury.Methods:A prospective cohort study was conducted. A total of 108 patients with acute brain injury admitted to the intensive care unit (ICU) of the Third Medical Center of the PLA General Hospital from January 2015 to December 2019 were enrolled. According to the patient's condition, dexmedetomidine contraindication and tolerance, and combined with the wishes of patients' families, they were divided into EGDS group and on-demand sedation group. Routine treatments such as surgery, mechanical ventilation, dehydration and reduction of intracranial pressure with mannitol, hemostasis or antiplatelets therapy were given according to the patient's condition. All patients were continuously given sufentanil by intravenous infusion for analgesia. Patients in the EGDS group were sedated by continuously intravenous infusion of dexmedetomidine (0.2-0.7 μg·kg -1·min -1) for 72 consecutive hours. Patients in the on-demand sedation group received intravenous bolus of propofol (0.5-1.0 mg/kg) when treatments were interfered due to agitation. Hemodynamic indexes [heart rate (HR), mean arterial pressure (MAP), cerebral perfusion pressure (CPP), intracranial pressure (ICP)], sedation indexes [bispectral index (BIS)], severity indexes [acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, Glasgow coma score (GCS)] and cerebral oxygen metabolism indexes [jugular venous blood lactate (Lac), jugular venous oxygen saturation (SjvO 2), cerebral arterial oxygen content (CaO 2), cerebral extraction rate of oxygen (CERO 2), cerebral arteriovenous blood oxygen content difference (a-vDO 2)] were compared between the two groups before sedation and at 24, 48 and 72 hours of sedation. Results:① Among the 108 patients, 3 patients with cerebral hemorrhage received secondary surgery or had worsening of cerebral hernia were excluded. 105 patients were enrolled in the study, including 54 patients in the EGDS group and 51 patients in the on-demand sedation group. There were no statistically significant differences in gender, age, type of craniocerebral injury, GCS score, proportion of mechanical ventilation and operation ratio between the two groups. ② Compared with before sedation, Lac, CERO 2 and a-vDO 2 of both groups gradually reduced over time of sedation while SjvO 2 and CaO 2 were gradually higher. Those changes were more quickly in the EGDS group, Lac, SjO 2, CERO 2 and a-vDO 2 significantly improved at 24 hours of sedation compared with those before sedation. Above indexes at 72 hours of sedation in the EGDS group were obviously better than those in the on-demand sedation group [Lac (mmol/L): 1.81±0.31 vs. 2.19±0.12, SjvO 2: 0.714±0.125 vs. 0.683±0.132, CaO 2 (mL/L): 201.21±15.25 vs. 179.65±14.07, CERO 2: (27.87±3.66)% vs. (33.00±2.58)%, a-vDO 2 (mL/L): 44.32±5.68 vs. 48.57±8.22, all P < 0.05]. ③ Compared with before sedation, HR, MAP and ICP decreased in the two groups over time while CPP, BIS and GCS score showed increasing trend, especially more quickly in the EGDS group, HR at 24 hours of sedation, MAP, CPP, BIS and GCS score at 48 hours significantly improved as compared with those before sedation. Hemodynamics and sedation related parameters and GCS score at 72 hours of sedation in the EGDS group were significantly better than those in the on-demand sedation group [HR (bpm): 70.69±7.80 vs. 79.85±9.77, MAP (mmHg, 1 mmHg = 0.133 kPa): 84.23±8.76 vs. 89.97±9.48, ICP (mmHg): 14.23±8.76 vs. 15.97±9.48, BIS: 60.56±24.58 vs. 56.86±33.44, GCS score: 8.06±3.63 vs. 7.86±2.98, all P < 0.05]. The APACHE Ⅱ scores were significantly reduced at 72 hours of sedation in both groups as compared with those before sedation, while there was no statistical difference between the two groups. Conclusion:Compared with the on-demand sedation, EGDS could reduce cerebral oxygen metabolism, improve the coma degree, and reduce the severity of the disease in patients with acute brain injury.

BACKGROUND: Exogenous neural stem cells (NSCs) can repair nerve and promote recovery of neurofunction following cerebral hemorrhage.OBJECTIVE: To observe the growth and development of NSCs in vitro, to evaluate the survival, migration and differentiation of transplanted NSCs surrounding hematoma and the possible recovery function of NSCs, and to investigate the repairing effect of NSCs on damaged neurofunction in cerebral hemorrhage model rats.DESIGN: Completely randomized grouping design and controlled animal study,SETTING: Department of Neurosurgery, Huashan Hospital, Fudan University.MATERIALS: Eighteen adult healthy male SD rats weighing 280-320 g were provided by Shanghai Animal Center of Chinese Science Academy. BrdU was provided by Neomarkers Company; rat-anti-glial fibrillary acidic protein (GFAP) and rabbit-anti-microtubule-associated protein-2 (MAP-2) by Chemicon Company.METHODS: This study was performed at the Laboratory of Anatomy and Histology & Embryology, Shanghai Medical College,Fudan University from February to December 2006. The NSCs was isolated, cultured, and evaluated from hippocampus of day E14fetal SD rats. Eighteen rats were randomly divided into control group, PBS group and NSC transplantation group. Cerebralhemorrhage rat models were established via injection of autoiogous arterial blood in caudate nucleus. Thirty minutes after model establishment, 5 μ L NSC suspension with the concentration of 2×1011 L-1 was transplanted at four points surrounding hematoma cavity in the NSC transplantation group. Transplantation of PBS and NSCs was the same as autoblood transplantation. Thirty minutes after model establishment, injuries at the four points were performed, and nothing was injected in the control group.MAIN OUTCOME MEASURES: Neurofunction was evaluated with forward limb scale and turning scale just soon after transplantation and at 1, 3, 5, 14, and 28 days after transplantation. Brain was colleted by anesthesia 28 days after model establishment.Differentiation of transplanted NSCs was detected through testing GFAP, MAP-2, and BrdU by using immunohistochemistry.RESULTS: ①Neurofunction scores: There was no significant difference 5 days after model establishment (P＞0.05). However, the scores were significantly improved in the NSC transplantation group 14-28 days after model establishment (P＜0.05).②lmmunofluorescent double labeling: Apoptosis ceils around hemotoma in the NSC transplantation group were less than those in the PBS group. BrdU and MAP-2 or GFAP-positive ceils were observed in cerebral tissue sections, and this suggested that NSCs could survive, migrate and differentiate in host brain and differentiate into neurons or astrocytes.CONCLUSION: NSC Transplantation contributes to the recovery of neurofunction in cerebral hemorrhage rats through differentiation into neurons or astrocytes.

ObjectiveTo explore the therapeutic effect of selective antagonist-AM630 of cannabionid receptor 2 (CB2) in treatment of the titanium particles-induced inflammatory osteolysis.MethodsForty-five female BALB/c mice, 6-8 weeks old, were involved in the study, of which 15 mice were used as skull donors and the rest experimental animals were randomly divided into three groups, ie, black group, control group and treatment group, 10 mice per group.The mice model with air-pouch osteolysis induced by the titanium particles were established.The mice in the treatment group were injected with CB2 selective antagonist-AM630 (200 μg · kg-1 · d-1) intraperitoneally from two days before establishment of the air-pouch osteolysis model to two weeks after establishment of the model.Then, the mice were sacrificed and the pouch tissues were collected for molecular and histological analyses.The pouch membrane thickness and cell infiltration were tested by using computerized image analysis system and HE staining respectively.Osteoclast-like cells in the pouch membrane were determined by using tartrate-resistant acid phosphatase (TRAP) staining.Quantitative real-time polymerase chain reaction (RT-PCR) was employed to detect the mRNA levels of CB2, IL-1 β, TNF-α, receptor activator of NF-κB ligand (RANKL)and receptor activator of NF-κB (RANK).ResultsThere exhibited apparent erythematous and oedematous changes in the control group, which was mitigated around the bone implants with AM630 treatment.Quantitative image analysis of the histological sections revealed significant difference of the pouch membrane thickness among three groups, (192.2 ± 19.4)μm in control group, (88.5 ± 14.7) μm in blank group and (122.1 ± 15.2) μm in treatment group (F = 101.74, P ＜ 0.05).Intensive TRAP staining was identified much in the control group but markedly reduced after AM630 treatment in the pouch tissues.RT-PCR showed that titanium particle stimulation could enhance the expressions of CB2, IL-1 β, TNF-α, RANKL and RANK gene in the air pouch tissues.However, the mRNA levels of these genes were markedly reduced after AM630 treatment, with statistical difference compared with control group (P ＜ 0.05).ConclusionsCB2 selective antagonist AM630 can inhibit the process of titanium particlesstimulated inflammatory reaction and osteoclast activation.Therefore, CB2 represents a new suitable therapeutic candidate for the prevention and treatment of aseptic loosening of the artificial joint.

Hybridomas producing monoclonal antibodies (McAb) directed against Trichomonas vaginalis have been produced by fusing NSI myeloma cells with spleen cells of BALB/c mice immunized with Trichomonas vaginalis.IFA technique was used to test the binding activity of four McAbs produced.The McAb belonged to the IgG subtypes IgGl(2A2,2A4 McAb),IgG3 (2H9 McAb) and IgG 2b (2A12 McAb).Three McAbs,designated 2A2,2A4,2A12,reacted with a surface membrane component of live Trichomonas vaginalis.One (2A12) of them produced com-plement-dependent cytolysis of the parasites.Others (2A2.2A4) produced complement-independent cytotoxicity of the parasites.2H9 McAb which reacted with the nucleus of the organisms did not agglutinate the parasites.The four McAbs which did not have cross reaction with some protozoa of Zoomastigophorea species were specific antibodies against Trichomonas vaginalis.(Figs.1-3)

Objective To investigate the influence of total progressively motile sperm count(TPMSC) after treatment on clinical outcomes of intrauterine insemination(IUI) with the husband′s sperm in ovulation-promoting cycles.Methods The clinical data in 4179 cases undergoing IUI with the husband′s sperm in ovulation-promoting cycles were retrospectively analyzed.The correlation between clinical pregnancy rate and TPMSC was analyzed.Results Among all the clinical data,TPMSC was to 100×106 in occasional live sperm.TPMSC<0.15×106 was in 15 cases,1 case had pregnancy (live sperm was occasionally seen on IUI day after sperm processing).Ten cases of TPMSC >60×106 had no pregnancy.A total of 4 154 cases of TPMSC (0.15-60.00)×106 were analyzed.The female age,duration of infertility,number of follicles and endometrial thickness(EDM) had no statistical differences among various groups.The clinical pregnancy rate was 13.5%(576/4 154),the group with the highest clinical pregnancy rate was (5.00-<10.00)×106.But there was no statistically significant difference in clinical pregnancy rate among groups(P=0.133).Conclusion Performing IUI in PMSC (0.15-60.00)×106 after processing can get preferable pregnancy rates.
