In order to evaluated the curative effect of rhIL-11 (Mega) on thrombocytopenia in chronic aplastic anemia (CAA) patients, ten CAA cases with thrombocytopenia after administration of conventional drugs were selected and subcutaneously injected 0.75 mg Mega per day in 1 - 2 courses of treatment on the basis of conventional therapy. Results showed that platelet counts were obviously increased and the bleeding symptoms were alleviated in all CAA patients after application of Mega for treatment. In conclusion, the rhIL-11 (Mega) could be used as an effective drug for treatment of thrombocytopenia in CAA patients.

AIM AND METHODSNew method to analyse nitrate and nitrite concentrations in saliva, serum and urine was developed using high performance liquid chromatography.

RESULTSThe whole isolation process was completed in less than 7 minutes, the determination linearity of nitrate and nitrite were 0.7 ng-100 ng and 5 ng-100 ng, respectively. MINIMUM: Detectable limits of nitrate and nitrite were 0.3 ng and 2 ng, respectively. Nitrate recovery ratio was 99%-102% and nitrite recovery ratio was 99%-104%. The RSD of nitrate and nitrite was 0.8% and 1.7%, respectively.

CONCLUSIONIn comparison with other methods available, the present method seems to be simpler, more sensitive and specific.

OBJECTIVETo describe the prevalence trend and epidemiological characteristics of neural tube defects (NTDs) in perinatal in Zhengzhou city from 1996 to 2005.

METHODSData collected from hospital were used to depict the epidemiology of NTDs in Zhengzhou. All perinatal fetuses born in hospitals had an access within 7 days after delivery. The prevalence were calculated by perinatal'year, sex, birth area (urban versus rural) and maternal age. All monitored perinatal (162,074) accounted for 32.66% from totals (496,203).

RESULTSAll 238 cases were found NTDs, and the overall prevalence rate was 14.68/10,000. The annual prevalence rate presented a decreasing trend during that period. The rates in rural and urban area, in male and female birth were 29.28/10,000 and 9.63/10,000, 11.42/10,000 and 17.74/10,000 respectively. There were significant differences among maternal-age-specific prevalence rates (chi2 = 22.952, P = 0.000). The rates of <20 years group(53.76/10,000) and >35 years group(21.74/10,000) were higher than others.

CONCLUSIONThe prevalence rates of NTDs in rural area is higher than that in urban, female's is higher than male's in Zhengzhou. The annual prevalence rates of NTDs presents a decreasing trend in the past ten years.

OBJECTIVETo analyze treatment and prognostic factors of 74 patients with dermatofibro-sarcoma protuberans (DFSP).

METHODSFrom August 1990 to November 1999, 74 patients with DFSP confirmed pathologically were treated. There were 52 males and 22 females with a median age of 37 years (range 4 to 80 years) on diagnosis. Seventeen patients were treated by extensive excision and 2 by limited excision. Fifty-two patients had surgical resection alone (S), and 22 postoperative radiotherapy (S + R) of 50-70 Gy. The multivariate parameters were analyzed using Cox model. Kaplan-Meier and Log-Rank test were used to evaluate the results of the recurrence-free survival.

RESULTSThe rate of recurrence was 28.4% for all patients. The 5-year recurrence-free survival rate (RFSR) was 66.6% and the 10-year RFSR was 52.5%. The 5-year and 10-year in the S group were 58.4% and 41.2%, compared with 90.0% and 83.3% in the S + R group (P < 0.05). The 5-year and 10-year RFSR in the pathologically positive margin group were 57.5% and 41.4% respectively, compared with the 75.0% and 56.6% in the pathologically negative group (P < 0.05). Multivariate analysis suggested radiotherapy and negative pathological margins were favorable prognostic factors.

CONCLUSIONPost-operation radiotherapy and pathological margin are the independent prognostic factors.

AIMTo explore the protective effects of ischemic preconditioning on the kidney injury following with ischemia/reperfusion (I/R) of limbs.

METHODSThe models of I/R injury of limbs were constructed in rabbits. The blood from right external jugular vein, renal artery and renal vein represent the peripheral blood, into and out-flowing kidney blood (IKB, OKB) respectively. Superoxide dismutase (SOD), malondialdehyde (MDA), blood uria nitrogen (BUN) in peripheral blood and SOD, MDA, nitric oxide (NO) in IKB and OKB were measured, as well as SOD, MDA, induced nitric oxide synthase (iNOS) in kidney were detected in different groups. The effects of ischemic preconditioning (IPC) on the kidney injury were observed.

RESULTSCompared with control group, the activity of SOD in peripheral blood, IKB, OKB and kidney decreased, and the content of MDA increased after 4 h ischemia followed by 4 h reperfusion. The content of BUN in peripheral blood, NO in IKB, OKB and iNOS in kidney increased remarkably as well. SOD increased and MDA, NO, BUN, iNOS decreased significantly by ischemic preconditioning (IPC) before ischemia/reperfusion. The correlation analysis indicated that MDA was negatively correlated with SOD and positively correlated with NO, BUN.

CONCLUSIONOxygen free radicals metabolic confusion of kidney occurred in the course of I/R of limbs, IPC could strengthen the resistance of peroxidation in kidney and had protective effects on the kidney injury following with ischemia/reperfusion (I/ R) of limbs

OBJECTIVETo compare the postoperative analgesic efficacy and safety of the non-addictive propacetamol hydrochloride (Pro-Bufferin) injection and dolantin in a prospective, randomized, double blind and controlled clinical trial.

METHODSAfter the pain intensity was assessed when the patients were undergone thoracic and abdominal selective surgery became fully conscious, 40 consecutive patients with moderate to severe postoperative pain (equivalent to Pain Grade I and II of American Anesthesia Association classification) were randomized into the study against the control groups. The two groups were similar for age, sex, height/weight, disease categories, operation categories, anesthesia methods and duration, vital signs, hepatorenal function, and blood cell count (P = 0.06-0.93). In the study group, 2 g propacetamol in 100 ml normal saline (NS) intravenously with 1.0 ml NS intramuscularly as the placebo control to dolantin were administered. In the control group, 1.6 g mannitose in 100 ml NS intravenously as the placebo control to propacetamol with 50 mg dolantin (1.0 ml) intramuscularly as the positive control to propacetamol were administered. The intensity change of postoperative pain was then evaluated 10 times with visual analog scale and verbal describing scale during 6 h from the beginning of propacetamol infusion. Vital signs and adverse reactions were also documented. After all data were put into the computer, the blinding codes were decoded and the statistic analysis was then made.

RESULTSThere was no significant difference (P = 0.93) about the area under the curve of "Pain Relieve Score vs. Time". The "starting to effect" time (15-30 min), analgesic duration (6 h) and the percentage of excellent or good analgesic effect (90%) in the two groups were the same. Adverse reactions didn't reached the statistic different level (P = 0.35).

CONCLUSIONSPropacetamol HCL injection 2 g intravenously could be an alternative to dolantin 50 mg intramuscularly for moderate to severe postoperative pain with its advantage of being non-addictive.
