ObjectiveTo identify the correlation factors for urosepsis shock after endourology surgery and analyze its clinical characteristics.MethodsFifty-eight patients with urosepsis without shock and 15 patients with shock were studied.Factors which may be correlated with the development of sepsis were analyzed including age,sex,ASA physical status,history of urinary tract infection,preoperative leukocyturia,urine bacteria culture,prophylactic antimicrobial treatment,pyonephrosis,type of surgery,duration of operation,blood leukocyte count and concentration of creactive protein at the end of surgery,the time when the signs of infection (shivering,agitation,nausea or vomiting) first appeared.Changes in BP in patients with urosepsis shock,scores for multiple organ dysfunction syndrome as well as treatment and prognosis were also recorded.ResultsFemale sex and early emergence of signs of infection after surgery were correlated with urosepsis shock.Abrupt hypotension was usually the first manifestation of urosepsis shook.The lowest systolic BP was positively correlated with the time when diagnosis of shock was made and negatively correlated with the length of ICU stay and the highest multiple organ dysfunction syndrome scores but not correlated with shock correction time.All patients with urosepsis shock recovered completely when discharged from hospital.ConclusionFemale sex and patients with early emergence of signs of infection are prone to develop urosepsis shock after endourology operation.The prognosis of urosepsis shock is good if diagnosed and treated in time.

Objective To observe the formation of Staphylococcus aureus biofilm and the inhibitory and dispersive effects of betaine on the biofilm.Methods The inhibitory and dispersive effects of 0.1％ betaine on the biofilm from 20 strains of Staphylococcus aureus were examined by crystal violet assay.Results All the 20 strains of Staphylococcus aureus formed biofilm.The biofilm of methicillinsensitive Staphylococcus aureus (MSSA) was formed in 24 hours with peak value of absorbance (A590 nm) (1.99 ± 0.53).The biofilm of methicillin-resistant Staphylococcus atureus(MRSA) was formed in 48 hours with peak value of absorbance(A590 nm) (1.13 ±0.47).After adding betaine,the absorbance(A590 nm) of MSSA biofilm fell down to(1.74 ± 0.61) in 24 hours,while the absorbance(A590 nm) of MRSA biofilm fell down to(0.40 ± 0.12) in 48 hours,which was significantly reduced compared with the controls (t =2.43,5.84,P ＜ 0.05 respectively).When adding betaine after the biofilm formed,the absorbancies (A590 nm) of both MSSA and MRSA showed no significant difference compared with the controls (P ＞ 0.05).Conclusion Betaine could inhibit biofilm formation of Staphylococcus aureus at concentration of 0.1％,but it could not disperse the mature biofilm of Staphylococcus aureus.

OBJECTIVETo observe the efficacy and safety of modified Shengma Biejia Decoction (MSBD) combined with CAG program in treating elderly acute myeloid leukemia (AML) patients with yin deficiency toxin stasis syndrome (YDTSS).

METHODSTotally 46 elderly AML patients were assigned to the treatment group (24 cases; treated with MSBD + CAG) and the control group (22 cases; treated with CAG + placebos of Chinese medicine) according to random digit table. The therapeutic course of CM placebo or MSBD was 21 days. The clinical efficacy and adverse reactions were observed. Meanwhile, physical state (ECOG Score), transfusion dependency, and TCM syndrome score were compared before and after treatment.

RESULTS(1) The complete remission rate was 54% (13/24) and the objective response rate (ORR) was 71% (17/24) in the treatment group, obviously higher than those of the control group [36% (8/22); 54% (13/24)], with statistical difference (P = 0.036, 0.042). When comparing the efficacy based on risk level, the moderate and poor ORR was 71% (10/14) and 67% (6/9) in the treatment group, and 57% (8/14) and 33% (2/6) in the control group, with statistical difference between the two groups (P = 0.048; P = 0.010). (2) Compared with before treatment in the same group, the ECOG score significantly decreased, the average infusion time of red cells and platelets were markedly prolonged in the treatment group after treatment (P < 0.05). ECOG score, the average infusion time of red cells and platelets were significantly better in the treatment group than in the control group after treatment (P < 0.05). (3) Compared with before treatment in the same group, scores of fever, hemorrhage, and bone pain were markedly reduced in the control group (P < 0.05); scores of fever, fatigue, hemorrhage, dry mouth, and bone pain were markedly reduced in the treatment group (P < 0.05). Better effect in relief of fever, fatigue, hemorrhage, dry mouth, and so on was obtained in the treatment group than in the control group (P < 0.05). (4) In aspect of hematotoxicity, the incidence of neutropenia, anemia, thrombocytopenia was obviously lower in the treatment group than in the control group [29.2% (7/24) vs 54.5% (12/22); 16.7% (4/ 24) vs 45.5% (10/22); 33.3% (8/24) vs 63.6% (14/22); P < 0.05]. The incidence of fatigue and anorexia was obviously lower in the treatment group than in the control group [37.5% (9/24) vs 63.6% (14/22), 37.5% (9/24) vs 81.8% (18/22); P < 0.05].

CONCLUSIONMSBD combined with CAG program in treating elderly AML patients with YDTSS, with efficacy enhancing toxicity reducing effect, had distinct advantages in improving physical condition and clinical symptoms, and reducing transfusion dependency.

The present study aimed to investigate the role of platelet-activating factor (PAF) in progesterone synthesis and vascular endothelial growth factor (VEGF) expression in rat luteal cells. Immature (25-28 days old) female Sprague-Dawley rats were injected subcutaneously with 50 IU pregnant mare serum gonadotrophin (PMSG), and 25 IU human chorionic gonadotrophin (hCG) 48 h later, to induce follicular development and luteum formation. On day 6 after hCG administration (the day of hCG administration was the first day), the rats were killed by guillotine and the ovarian luteal cells were collected. After incubation for 24 h, luteal cells were incubated without or with different doses (0.1 μg/mL, 1 μg/mL, 10 μg/mL) of PAF at 37 °C (5% CO(2)) for 24 h, and then progesterone concentration was evaluated by radioimmunoassay (RIA); apoptotic rate and VEGF mRNA expression in luteal cells were assessed by flow cytometry and RT-PCR, respectively. The results showed that PAF promoted progesterone production, with a maximal effect at 1 μg/mL (P<0.05); PAF increased apoptotic rate but not in a dose-dependent manner, and 10 μg/mL PAF enhanced apoptotic rate significantly (P<0.05); furthermore, PAF stimulated VEGF mRNA expression in luteal cells, especially at 1 μg/mL (P<0.01). It is suggested that PAF regulates progesterone synthesis and VEGF mRNA expression in luteal cells to mediate corpus luteum formation in rat ovary.

OBJECTIVETo evaluate the curative effects of Betamethasone for treatment of voice hoarseness of chronic hypertrophic laryngitis.

METHODSFrom July, 2001 to December, 2002, 48 cases of the chronic hypertrophic laryngitis had been treated by injected of Betamethasone at vocal cords. Fundamental frequency (FO), jitter, shimmer, normalized noise energy (NNE) acoustics' parameters were tested and paired t test were calculated. The voice quality of 1 month and 6 months after treatment were synthetically graded, one-way ANOVA and the DANCAN test were conducted.

RESULTSEight cases were injected under surface anesthesia with indirect laryngoscopy at the clinic service. Thirty-eight cases were injected under general anesthesias with micro-laryngoscopes. After six months following up, the voice hoarseness was obviously improved, the congestion or oedema of vocal cord was lessened, and the voice quality was improved as well. The results of F0, jitter, shimmer, NNE acoustics' parameters after treatment 6 months showed: 8 of 48 cases (17.39%) had treatment effect, 22 out of 48 cases (47.83%) had obviously effect, 10 out of 48 cases (21.74%) had cured. The total effectiveness had reached 86.96% (40 of 48 cases). Six of 48 cases (13.04%) was failure.

CONCLUSIONVocal cord injection of Betamethasone for the hoarseness of chronic hypertrophic laryngitis is an effective treatment method.

OBJECTIVETo investigate the potential effects on cognitive function, prognosis, and neuropeptide levels of patients in response to combination therapy with ornithine aspartate plus naloxone for hepatic encephalopathy.

METHODSEighty-four consecutive patients diagnosed with hepatic encephalopathy were randomly divided into two equal groups. The control group (n = 42) received traditional medical treatment, and the research group (n = 42) received the traditional medical treatment as well as the combination therapy with ornithine aspartate plus naloxone. The supplemental treatment was comprised of daily intravenous injection of 10-15 g ornithine aspartate in 250 ml of 5% glucose plus intravenous drip of 3 mg naloxone in 100 ml of 5% glucose, and was given in 7-day cycles for one or two cycles. The cognitive function of patients was assessed by Hasegawa Intelligence Scale (HDS) and Mini-Mental State Examination (MMSE) questionnaires. The effective rate and time duration from coma to consciousness were recorded. Changes in blood ammonia level, markers of liver function, and neuropeptide levels were measured by standard biochemical assays. Intergroup differences were assessed by the Chi-squared test.

RESULTSThe HDS and MMSE scores of the research group were significantly higher than those of the control group after therapy. The effective rate, time duration from coma to consciousness, blood ammonia, the liver function markers alanine aminotransferase, gamma-glutamyl-transpeptidase and total bilirubin, and the neuropeptides arginine vasopressin and beta-endorphin were remarkably improved after treatment in the research group, as compared with that in the control group.

CONCLUSIONSupplementing the traditional treatment for hepatic encephalopathy with ornithine aspartate plus naloxone combination therapy provides better therapeutic outcome than traditional treatment alone.
