Objective To observe the clinical effects of chemotherapy with intraperitoneal hyper-thermal perfusion for malignant ascites. Methods 40 patients with malignant ascites were randomly divided into two groups. In the treated group, 21 patients underwent intraperitoneal hyperthermal perfusion and local thermotherapy. 19 patients in the control group received commonly intraperitoneal perfusion. Results The CR, PR patients were 6,10 and 0,7 in the treated group and control group, respectively. The efficacy rate in the treated group was significantly higher than that in the control group. 2 patients oc-cured bellyache in the treated group and 1 patient in the control group, there was no statistically significant difference between the two groups. Conclusion Chemotherapy with intraperitoneal hyperthermal perfusion can significantly improve the therapeutic effects for malignant ascites, and has no more side effects.

Although it has been known that human seminal plasma (HSP) suppresses immune responses, there is little data concerning in vivo effects on humoral and cellular immune responses, particularly on immediate hypersensitivity. Thus, the present study was undertaken in an effort to investigate the in vivo effect of HSP on humoral and cellular immune responses, including active systemic anaphylaxis (ASA) in mice. The immune responses investigated were delayed-type hypersensitivity (DTH) reaction to sheep red blood cell (SRBC) or human sperm antigen, hemagglutinin response, and active systemic anaphylaxis induced by egg albumin (OVA). Effect of HSP on Candida albicans infection was also studied. It was found that intraperitoneal administration of HSP before or after immunization with SRBC significantly suppressed the DTH to SRBC. HSP given after immunization with SRBC failed to suppress hemagglutinin response whereas HSP given before immunization with SRBC significantly suppressed the hemagglutinin response. Interestingly, intravaginal administration of HSP together with human sperm significantly suppressed DTH to human sperm as measured by footpad swelling reactions. HSP inhibited phagocytic function of macrophage and enhanced germ tube producing phagocytosed yeasts. Colony forming unit (CFU) of Candida albicans in kidneys of HSP-treated mice were enumerated. HSP given to mice before infection significantly increased the number of CFU in kidneys, strongly suggesting that HSP may decrease the resistance of mice to Candida infection. For the ASA experiment, mice were sensitized by i.p. injection of 500 ug OVA, 1.0 mg alum and 2x1000000000 Bordetella pertussis in 0.5 ml PBS and were challenged by i.v. inje-ction of 0.25 ml PBS containing 500 big OVA 18 days after sensitization. Surpris-ingly,HSP injection before ASA induction inhibited intensity of ASA and improved survival of anaphylaxis. Taken together, this study strongly suggests that HSP may suppress in vivo immediate and delayed immune responses and that HSP may decrease the resistance against Candida albicans infection, and this study may be the first to show the immunosuppressive effect of HSP on the induction of active systemic anaphylaxis.

OBJECTIVETo compare the clinical efficacy of 3 different treatment programs for oligospermia patients of Shen-essence deficiency syndrome (SEDS).
METHODSTotally 450 male patients were randomly assigned to 3 groups, i.e., the treatment group, the control group 1, and the control group 2, 150 in each group. Patients in the treatment group were treated by Bushen Yijing Decoction (BYD), tamoxifen tablet (TT), Licorzine Capsule (LC), and Vitamin E Soft Capsule (VESC). Those in the control group 1 were treated by BYD, LC, and VESC. Those in the control group 2 were treated by TT, LC, and VESC. All patients were treated for 3 months. Their pregnant rates were compared. Clinical efficacies of each Chinese medical symptom and sperm parameters [sperm density, grade a sperm motility rate, grade (a + b) sperm motility rate, grade (a + b + c) sperm motility rate, and normal sperm morphology rate] were compared before and after treatment.
RESULTSAt 3 months after treatment 61 patients were pregnant in the treatment group, 36 patients were pregnant in the control group 1, and 30 patients were pregnant in the control group 2. The differences in the sperm density, grade a sperm motility rate, and grade (a + b) sperm motility rate, and grade (a + b + c) sperm motility rate between before and after treatment were significantly higher in the treatment group than in the control group 1 and the control group 2 (P < 0.01). The difference in the normal sperm morphology rate between before and after treatment was obviously higher in the treatment group and the control group 1 than in the control group 2 (P < 0.01). Better results were obtained in the treatment group and the control group 1 in improving the sexual apathy, soreness and weakness of waist and knees, impotence, premature ejaculation, seminal emission, dizziness, tinnitus, forgetfulness, alopecia, when compared with the control group 2 (P < 0.01, P < 0.05). There was no statistical difference in the total effective rate of improving Chinese medical symptoms between the treatment group and the control group 1 (P > 0.05).
CONCLUSIONBYD combined with TT, LC, and VESC could significantly improve sperm qualities and clinical Chinese medical symptoms of oligospermia patients of SEDS.

【Objective】 To establish an enzyme-linked immunosorbent assay (ELISA) method for the determination of residual human coagulation factor Ⅺ in human prothrombin complex and validate the method. 【Methods】 Human factor Ⅺ was reacted with the capture antibody coated on the microtiter plate. After appropriate washing steps, biotinylated primary antibody was bound to the captured protein. Excess primary antibody was washed away and bound antibody was reacted with horseradish peroxidase conjugated streptavidin. TMB substrate was used for color development at 450 nm. The dilution reliability, accuracy, specificity, repeatability, intermediate precision, linearity, range and durability were verified. 【Results】 The verification results showed that the accuracy and specificity of this method met the experimental requirements, with an average recovery rate of 109.2% and RSD of 6.93%. The repeatability RSD was 6.78%, and the intermediate precision RSD was 6.75%, indicating good precision. The linear regression correlation coefficient of standard curve was 0.999 9, showing good accuracy and precision within the linear range. The durability was verified by the incubation time and the validity period of reagent kit opening. The results showed that the RSD of the incubation time change was 6.62%, indicating that the incubation time of this detection method was controlled between 28 to 32 minutes, and there was no significant impact on the results. The RSD of the detection results before and after the reagent kit was opened and stored under conditions for 7 days was 3.84%, indicating that the preservation of the reagent kit according to the conditions for 7 days after opening has no effect on the FⅪ detection results. Both indicated that the method had good durability. The dilution reliability results showed that there was a "hook" effect in the detection of FⅪ residue in human prothrombin complex, which could be solved by diluting 100 to 200 times. 【Conclusion】 This method can be used for the determination of FⅪ residues of human prothrombin complex in laboratory.

Neuregulin-1 (NRG1) plays important roles in the development and plasticity of the brain, and has also been reported to exhibit potent neuroprotective properties. Although ErbB4, a key NRG1 receptor, is expressed in multiple regions in the adult animal brain, little is known about its role in Alzheimer's disease (AD). AD is characterized by progressive impairment of cognition and behavioral disturbance that strongly correlate with degeneration and death of neurons in the cerebral cortex and limbic brain areas, such as the hippocampus and the amygdala. Here, we show that the ErbB4 and phospho-ErbB4 immunoreactivities were higher intensity in the neurons of the CA1-2 transitional field of AD brains as compared to age-matched controls. Also, ErbB4 expression was increased in the neurons of the cortico medial nucleus amygdala, human basal forebrain and superior frontal gyrus of AD brains. In cerebral cortex and hippocampus of amyloid precursor protein/presenilin 1 double transgenic mice, ErbB4 immunoreactivity significantly increased in comparison to age-matched wild type control. These results suggest that up-regulating of ErbB4 immunoreactivity may involve in the progression of pathology of AD.

Neuregulin-1 (NRG1) signaling participates in the synaptic plasticity, maintenance or regulation of adult brain. Although ErbB4, a key NRG1 receptor, is expressed in multiple regions in the adult animal brain, little is known about its localization in Alzheimer's disease (AD) brains. We previously reported that ErbB4 immunoreactivity showed regional difference in the hippocampus of age-matched control. In the present paper, immunohistochemical characterization of the distribution of ErbB4 receptor in the hippocampus relative to pathology staging were performed in age-matched control (Braak stage 0, n=6) and AD (Braak stage I/V, n=10). Here, we found that ErbB4 immunoreactivity was significantly increased in apoptotic hippocampal pyramidal neurons in the brains of AD patients, compared to those of age-matched control subjects. In AD brains, ErbB4 immunoreactivity was demonstrated to colocalize with the apoptotic signal Bax in apoptotic hippocampal pyramidal neurons. These results suggest that up-regulation of ErbB4 immunoreactivity in apoptotic neuron may involve in the progression of pathology of AD.

BACKGROUND: In the present study, we examined the effect of morphine on NO- and peroxynitrite-induced cell death using a human neuroblastoma SH-SY5Y cell line which abundantly expresses micro, delta and K-opioid receptors. METHODS: The cultured cells were pretreated with morphine (100 micrometer) and exposed to 3-morpholinosydnonimine (SIN-1, 1mM). Agarose gel electrophoresis of DNA was done with the extracts from SH-SY5Y cells. The cells were treated with selective ligands for opioid receptor subtypes and with PI3-kinase inhibitors. Cell damage was assessed by using an MTT assay. Spectrophotometric absorption spectra were measured from the mixture of morphine (100 micrometer) plus peroxynitrite (1 mM) at room temperature. RESULTS: SIN-1 treated cells showed the occurrence of a specific form of chromosomal DNA fragmentation which pretreatment with morphine inhibited. The selective ligands for opioid receptor subtypes, [D-Ala2, N-Me-Phe4, Gly-ol5]enkephalin (DAMGO, micro-opioid receptor agonist), [D-Pen2,5] enkephalin (DPDPE, delta-opioid receptor agonist) and U-69593 (K-opioid receptor agonist) at a concentration of 10 micrometer did not prevent the cell death induced by SIN-1. Naloxone (20 micrometer) hardly antagonized the effect of morphine in SIN-1-induced cell death. The PI3-kinase inhibitors Wortmannin and LY294002 did not inhibit the action of morphine on apoptotic cell death. In the measurements of spectrophotometric absorption spectra, the peak of the absorbance of the mixture of morphine plus peroxynitrite at 295 300 nm disappeared three minutes after mixing. CONCLUSIONS: The present study showed that morphine protected the human neuroblastoma cell line,SH-SY5Y, from peroxynitrite-induced apoptotic cell death. However, it is suggested that the protective action of morphine is not via the activation of opioid receptors and/or the PI3-kinase pathway but possibly via direct chemical reaction.

We have cloned a cDNA encoding a cysteine proteinase of the Acanthamoeba healyi OC-3A strain isolated from the brain of a granulomatous amoebic encephalitis patient. A DNA probe for an A. healyi cDNA library screening was amplified by PCR using degenerate oligonucleotide primers designed on the basis of conserved amino acids franking the active sites of cysteine and asparagine residues that are conserved in the eukaryotic cysteine proteinases. Cysteine proteinase gene of A. healyi (AhCP1) was composed of 330 amino acids with signal sequence, a proposed pro-domain and a predicted active site made up of the catalytic residues, Cys(25), His(159), and Asn(175). Deduced amino acid sequence analysis indicated that AhCP1 belongs to ERFNIN subfamily of C1 peptidases. By Northern blot analysis, no direct correlation was observed between AhCP1 mRNA expression and virulence of Acanthamoeba, but the gene was expressed at higher level in amoebae isolated from soil than those from clinical samples. These findings raise the possibility that Ahcp1 protein may play a role in protein metabolism and digestion of phagocytosed bacteria or host tissue debris rather than in invasion of amoebae into host tissue.

BACKGROUND: Antihypertensive agents such as verapamil and esmolol are well known for their effects of hemodynamic stabilization on tracheal intubation. However, our previous study, Verapamil and esmolol did not attenuate heart rate and blood pressure. The aim of the present study was to evaluate the efficacy of combined administration of these drugs for controlling hemodynamic responses to tracheal intubation. METHODS: Forty-eight patients, ASA physical status I or II, were randomly assigned to one of four groups (n = 12 each):normal saline (control), verapamil 0.1 mg/kg, esmolol 1 mg/kg, and verapamil 0.05 mg/kg mixed with esmolol 0.5 mg/kg. Anesthesia was induced with thiopental 5 mg/kg intravenously, and then saline, verapamil, esmolol or the mixed drugs were administered as an intravenous bolus, and immediately followed by succinylcholine 1.5 mg/kg. Tracheal intubation was performed 90 s after intravenous injection of experimental drugs. Systolic and diastolic blood pressure and heart rate were measured before induction and every minute for 5 minutes after tracheal intubation. RESULTS: There was a significant attenuation in systolic blood pressure after tracheal intubation in the verapamil and mixed groups compared to the control and esmolol groups. Heart rates were significantly lower in the esmolol and mixed groups than in the verapamil groups after tracheal intubation. CONCLUSIONS: Combined administration of Verapamil 0.05 mg/kg with esmolol 0.5 mg/kg attenuated increases in blood pressure and heart rate after tracheal intubation.

OBJECTIVETo study an epidemic of human lung plague fulminant from September to October, 2004 in Nangqian county, Qinghai province.
METHODSCases were diagnosed through data from epidemiological, clinical, bacteriological, serological and autopsy studies.
RESULTS14 patients were identified, ending up with 6 deaths and 8 cured. The first case was diagnosed as primary pesticemia late progressed to lung plague. 4 cases were transformed from pesticemia out of 13, leaving the 9 cases as primary lung plague. Situation was under complete control through routinely handling the plague focus.
CONCLUSIONThe first case was bitten by the infected fleas which parasitized the marmota preyed on a dog but later these fleas were brought into the tent by the dog. The others cases were infected through droplets or dust. Programs on monitoring and controling the amount of marmotas and fleas should to be strengthened to prevent the epidemics of plague in the area.
