OBJECTIVETo observe the efficacy of Xingnaojing Injection (XI) in treatment of sepsis-associated encephalopathy (SAE).

METHODSTotally 65 SAE patients were retrospectively analyzed at EICU from September 2010 to September 2013. They were assigned to the control group (32 cases) and the treatment group (33 cases) according to whether they received XI. Patients in the control group received anti-infection and symptomatic support, while those in the treatment group were intravenously injected with XI at 20 mL per day for additional 7-10 days. The fever clearance time, Glasgow coma scale (GCS), C-reactive protein (CRP), neuron-specific enolase (NSE), and improvement of electroen-cephalogram (EEG) were observed in the two groups.

RESULTSCompared with the control group, the fever clearance time was shortened, CRP levels decreased, GCS score and efficacy of EEG was alleviated in the treatment group after treatment with statistical difference (P < 0.05). No adverse reaction occurred during medication.

CONCLUSIONX1 was safe and effective in treatment of SAE.

OBJECTIVETo investigate the usefulness of percentage of free prostate specific antigen (FPSA/TPSA) in serum/PSA density [(F/T)/PSAD] in the diagnosis of prostate cancer.

METHODSTwo hundred and four patients who had been carried out transrectal ultrasound guided prostate biopsy, were involved in this study. Among them, 90 patients were proved to be suffering from prostate cancer, and other 114 patients were identified as benign prostate hypertrophy. The effect of total serum PSA level, FPSA/TPSA, PSAD and (F/T)/PSAD in the diagnosis of prostate cancer were investigated, and at the same time, selecting patients who should be carried out a prostate biopsy.

RESULTSThe mean values of (F/T)/PSAD were significantly lower for patients with prostate cancer in different PSA levels (<4.0, 4.0-, 10.1-, >20.0 microg/L), when compared with benign prostate hypertrophy patients. This difference has arrived statistical significance (P < 0.05). (F/T)/PSAD could provide higher specificity for diagnosing prostate cancer than FPSA/TPSA or PSAD. Among all patients, at the same higher sensitivity (about 90%), the specificity of FPSA/TPSA, PSAD and (F/T)/PSAD was 31.6%, 45.6% and 64.0%, respectively. At the same time, it was suggested that clinicians use different cutoffs for (F/T)/PSAD in different PSA level. When PSA level of patients was no more than 4.0 microg/L, 2.5 as the commended cutoff for (F/T)/PSAD was preferred; if PSA level was between 4.0 microg/L and 20.0 microg/L, 0.8 was a more suitable cutoff; 0.5 also could be taken as an appropriate cutoff in case of PSA level being higher than 20.0 microg/L.

CONCLUSIONSKeeping high sensitivity, using of (F/T)/PSAD can improve the diagnostic specificity of prostate cancer significantly.

OBJECTIVETo evaluate the detection of prostate cancer in different prostate specific antigen (PSA) level and the predict value of PSA, digital rectal examination (DRE), transrectal ultrasound scan (TRUS) and PSA density (PSAD).

METHODSThe clinical data of 634 cases who had underwent transrectal ultrasound guided systematic sextant prostate biopsies between April 1996 to December 2002 due to being suspicious of prostate cancer were retrospectively analyzed. The detection of prostate cancer in different PSA groups, namely PSA < or = 4.0, 4.1-, 10.1-, > 20.0 microg/L, and the predict values of PSA, DRE, TRUS and PSAD were statistically analyzed using t test, chi2 test and logistic regression analysis.

RESULTSThe rates of prostate cancer detection in different PSA groups were 11.6%, 26.8%, 39.8% and 68.6%, respectively. The higher the PSA, the higher the rate of prostate cancer detection, the same was the positive predictive value of DRE and TRUS. The sensitivity and specificity of PSA > 4.0 microg/L were 93.0% and 33.0%, and the efficiency of DRE and TRUS were very low. Logistic regression analysis indicated that PSAD was the most risk factor of prostate cancer in the group of PSA 4.1-20.0 microg/L (OR = 687.09 +/- 646.96, P = 0.000).

CONCLUSIONSThe rates of prostate cancer detection in different PSA groups are different compared with other countries. The screening roles of DRE and TRUS are dependent on PSA level. Utilization of the screening protocol which to stratify cases into three PSA groups, namely PSA < or = 4.0, 4.1 - 20.0, > 20.0 microg/L, can elevate the positive rate of prostate biopsies without sacrificing cancers detected.

The aim of this study was to explore the protective effect of compound tianpupian (TPP) against (2)O(2)-induced the apoptosis of murine splenic lymphocytes and its mechanism. The cell apoptosis rate was detected by MTT method; the cell apoptosis and mitochondrial membrance potential were detected by flow cytometry (FCM) with Annexi-V/PI double staining and JC-1 staining method, respectively; and caspase 3 relative activity was determined by colorimetry. The results indicated that after treating with (2)O(2), the absorbance value of cultured lymphocytes and the red/green ratio of JC-1 were reduced, and the apoptotic rate and caspase 3 activity were increased, coculture of (2)O(2)-treated cells with compound TPP increased the cell absorbance ratio and red/green rate of JC-1, while reduced the apoptosis rate and caspase 3 activity. It is concluded that compound TPP alleviates intracellular oxidative damages and dose-dependently inhibited apoptosis of murine splenic lymphocytes through reducing mitochondrial membrane potential and inhibiting caspase 3 activity. This suggests that compound TPP is a potential anti-apoptotic agent.

Isopentenyl diphosphate isomerase (IDI) is a key enzyme in the regulation of triterpenes biosynthesis and plays an important role in ginsenoside biosynthesis. In this study, two IDI genes, PvfIDI1 (GenBank No. MZ736417) and PvfIDI2 (GenBank No. MZ736418) were cloned from Panax vietnamensis var. fuscidiscus. The open reading frame of both PvfIDI1 and PvfIDI2 was 924 bp encoding 307 amino acids. The molecular weights of PvfIDI1 and PvfIDI2 were 34.84 kDa and 34.66 kDa, respectively, with theoretical pIs of 6.01 and 5.66. Bioinformatic analysis indicated that PvfIDI1 and PvfIDI2 contained two conserved sequences: TNTCCSHPL and WGEHELDY. Phylogenetic analysis showed that PvfIDI1 and PvfIDI2 were closely related to Panax notoginseng IDI. Expression analysis showed that both PvfIDI1 and PvfIDI2 genes are expressed in root, rhizome, stem and leaf of P. vietnamensis var. fuscidiscus. However, PvfIDI1 is highly expressed in the rhizome and PvfIDI2 is highly expressed in the stem. PvfIDI1 and PvfIDI2 recombinant proteins were expressed in E. coli; a functional coloration experiment showed that PvfIDI1 and PvfIDI2 could promote the accumulation of lycopene, indicating that both PvfIDI1 and PvfIDI2 encode functional IDI enzymes. The cloning and functional studies on PvfIDI1 and PvfIDI2 provide a foundation for the further study of IDI and the regulation of ginsenoside biosynthesis in P. vietnamensis var. fuscidiscus.

OBJECTIVETo evaluate the effect of the aluminum hydroxide (Al-OH) adjuvant on the 2009 pandemic influenza A/H1N1 (pH1N1) vaccine.

METHODSIn a multicenter, double-blind, randomized, placebo-controlled trial, participants received two doses of split-virion formulation containing 15 μg hemagglutinin antigen, with or without aluminum hydroxide (Al-OH). We classified the participants into six age categories (>61 years, 41-60 years, 19-40 years, 13-18 years, 8-12 years, and 3-7 years) and obtained four blood samples from each participant on days 0, 21, 35, and 42 following the first dose of immunization. We assessed vaccine immunogenicity by measuring the geometric mean titer (GMT) of hemagglutination inhibiting antibody. We used a two-level model to evaluate the fixed effect of aluminum Al-OH and other factors, accounting for repeated measures.

RESULTSThe predictions of repeated measurement on GMTs of formulations with or without Al-OH, were 80.35 and 112.72, respectively. Al-OH significantly reduced immunogenicity after controlling for time post immunization, age-group and gender.

CONCLUSIONThe Al-OH adjuvant does not increase but actually reduces the immunogenicity of the split-virion pH1N1 vaccine.

OBJECTIVETo evaluate and compare the efficacy and safety of titanoreine cream with compound carraghenates suppository in the treatment of mixed hemorrhoids.

METHODSTwo hundred and fifty-two patients with mixed hemorrhoids were enrolled in this randomized,open, multicentral trial. Patients applied titanoreine cream (study group, n=133) or compound carraghenates suppository (control group, n=119). The symptomatic relief including pain,bleeding and edema was evaluated by scoring system at 30 minutes, 3 hours, 6 hours, 1 day, 2 days, 3 days, 4 days, 6 days after administration.

RESULTSSymptoms were significantly improved in both groups (87.3%, 94.8%, respectively) excepting symptom of pain relief, but there was no significant difference between two groups (P > 0.05). The pain scores were lower at every observing point in the study group than those in the control group (P< 0.05). The proportions of the patients with pain relief and all symptoms relief were both higher in the study group than that in the control group at 30 min, 3 h after drug used (both P< 0.01). No side effect was found during the triad.

CONCLUSIONTitanoreine cream has predominance of relieving pain and response time compared with compound carraghenates suppository, but other effects on mixed hemorrhoid are similar between the two groups.
