ObjectiveTo study the quality control methods for 99Tcm-TRODAT-1 kit and injection.MethodsThe appearance,pH,contents of the bases,the labeling yield,asepsis and bacterial endotoxins of 99Tcm-TRODAT-1 kits from three different batches were examined.The kit stability was estimated under different conditions.The transparence,pH,radiochemical purity,half-life,asepsis and bacterial endotoxins of 99Tcm-TRODAT-1 injection were tested.ResultsThe 99Tcm-TRODAT-1 kit and injection were both achromous and transparent,with pH values being 5.9 ± 0.1 and 5.5 - 7.0 respectively.The contents of stannous chloride and TRODAT-1 were stable.The labeling yield of the kit and the radiochemical purity of the injection were both ≥95％.The asepsis test demonstrated that the characters of 99Tcm-TRODAT-1 kit and injection were qualified.TRODAT-1 kit was stable at 0 -4 ℃ for 6 months or at room temperature (20 -25 ℃ )for 10 days,and the radiochemical purity of the injection was still ＞ 90％ at room temperature for 8 hours.ConclusionsThe quality control methods for 99Tcm-TRODAT-1 kit are simple and practical.The kit and injection are qualified and can be used for clinical application.

OBJECTIVETo investigate the clinical features of Crohn disease according to the Montreal classification.

METHODSClinical data of 43 surgical patients with Crohn disease (surgical group) and 125 non-surgical patients with Crohn disease (non-surgical group) were retrospectively analyzed and compared between two groups. The Montreal classification was used.

RESULTSIn the surgical group, 28 patients (65.1%) were A2, 14 (32.6%) were A3 and only one was A1, which was not significantly different as compared to the non-surgery group. The proportions of L1, L2, L3, and L4 subtype in the surgical group were 41.9%, 25.6%, 30.2%, and 2.3%, respectively, which was not significantly different as compared to that in the non-surgery group. In the surgical group,B1 disease was found in 1 case (2.3%), B2 in 26 cases (60.5%), and B3 in 16 cases (37.2%), while in the non-surgical group, B1 was found in 79 cases (63.2%), B2 in 44 cases (35.2%) and B3 in 2 cases (1.6%). Differences were significant between two groups in disease behavior (P=0.001, P=0.004, P=0.001).

CONCLUSIONSMost surgical patients of Crohn disease are A2. L1 and L3 are the main lesion location. As disease behavior, B2 and B3 are the main reasons for operation.

OBJECTIVE: To explore the clinical efficacy of intrathecally administered low dose sufentanil-bupivacaine in transurethral resection of the prostate (TURP). METHODS. Ninety patient (ASA I - III) undergoing TURP were randomly divided into 3 groups (n = 30); Group A, B and C. Group A received 7.5 mg bupivacaine + 5 microg sufentanil + 10% glucose; Group B received 7.5 mg bupivacaine + 7.5 microg sufentanil + 10% glucose; Group C received 15 mg bupivacaine + 10% glucose. The volume was 3 mL in every group. SP, DP, HR, SpO2, the degree of motor and sensory blockade and the side effect were observed. RESULTS: SP/DP was significantly decreased in Group C than that in Group and Group B (p<0.05), HR and SpO2 in group B were decreased to different degrees 15 min after the injection (p<0.05). The complete recovery time of motor nerve blockade and the regression time of sensory blockade were obviously prolonged in Group C (p<0.05). There were no significant differences in analgesic effect among the three groups during the operation, but the incidence of pruritus was higher in both group A and Group B than that in Group C during the first 24 hours after the injection. CONCLUSION Spinal anesthesia with low dose sufentanil-bupivacaine possesses relatively steady hemodynamics. The blockade degree of motor and sensory blockade in this spinal anesthesia is lower than that in standard spinal bupivacaine in TURP.

OBJECTIVE: To evaluate the effect of intrathecal pumping tramadol on cell-mediated immunity in rats with formalin inflammatory pain. METHODS: Thirty-two Sprague-Dawley adult male rats weighting 250 approximately 300 g were randomly divided into 4 groups (n=8 in each group):Saline group (NS) and 3 tramadol groups (T1,T2,and T3). The rats were anesthetized with intraperitoneal chloral hydrate (300 approximately 350)mg/kg. Microspinal catheter was inserted into the subarachnoid space at the lumber region according to modified Yaksh techniques. In the tramadol groups,after 5 days tramadol was continuously infused through the spinal catheter at 50 (T1),25 (T2), and 12.5 microg/h (T3) for 7 days. In the NS group normal saline was continuously infused instead of tramadol. On Day 7 formalin (5%, 50 microL) was injected into the plantar surface of the left hindpaw. The number of flinches, lickings and total time of licking was recorded for 60 min.Pain intensity scoring(PIS)(0 approximately 3;0= no pain, 3=severe pain) was used to assess the antinociceptive effect of intrathecal tramadol. The rats were killed after the evaluation of pain intensity. Body weight and spleen weight were measured and spleen index (spleen weight/body weight) was calculated. T-lymphocyte function was evaluated based on Concanavalin-A(ConA) induced splenocyte proliferation. A modified lactic acid dehydrogenase(LDH) release assay was done to assess the NK cell activity. Phenotypic expressions of cell surface markers of T lymphocyte subsets (CD3+, CD3+ CD4+, CD3+ CD8+, and CD4+/ CD8+) and NK cell(CD161+) in the spleen were analyzed by flow cytometry. RESULTS: The PIS scores were significantly lower in the T1,T2,and T3 groups than those in the NS group. The spleen index and splenocyte proliferation induced by ConA were significantly suppressed in the T1 group,and the phenotypes of T lymphocyte subsets were significantly changed,but no significant difference was found in the T2 and T3 groups compared with the NS group. There were no differences in NK cell activity in the 3 tramadol groups from the control group. CONCLUSION Intrathecal pumping tramadol has significantly antinociceptive effect. Intrathecal pumping higher dosage tramadol (50microg/h) suppresses T lymphocyte proliferation and alteres T lymphocyte subset phenotype but does not affect NK cell activity. General analgesic dosage tramadol (25 and 12.5 microg/h) has no effect on the immune function.

Objective To provide the basis for clinical acquired immunodeficiency syndrome (AIDS) surveillance and to avoid cross infection in hospital,we study the infection status of AIDS in Shandong province.Methods The fourth-generated Akzo's ELISA kit and the fourth generated Immunoluminometric detection reagent were used for HIV antibody screening for 399 303 cases of both inpatients and outpatients from Jan.2003 to Dec.2011.Beijing WanTai ELISA kit and Se-marked rapid detection reagent were used for re-detection,and the positive samples were sent to the local CDC for confirming test by Western Blot.Results The HIV-1 antibody detection results of 129 (0.3230‰)patients were confirmed to be positive,including 54 (0.1352‰) cases of outpatients and 75 (0.1878‰)cases of inpatients.HIV infection rates in outpatients from 2003 to 2011 were 0.050‰,0.030‰,0.111‰,0.120‰,0.124‰,0.113‰,0.148‰,0.201‰,0.2152‰; and that in inpatients were 0.150‰,0.089‰,0.138‰,0.144‰,0.104‰,0.132‰,0.197‰,0.329‰,0.313‰ respectively.Among these inpatients,there were 61 cases of medical patients and 14 cases of surgical patients,and most were youths and farmers.Conclusions HIV infection rate was increasing year by year.Most inpatients whose HIV-1 antibody was positive were in the phase of AIDS.Therefore,it's very necessary to execute routine testing for inpatients and outpatients who need special examination for early diagnosis of HIV infection.

Objective To investigate the therapeutic effect and mechanism of astragaloside Ⅳ on systemic lupus erythematosus(SLE)mice.Methods A total of 40 female spontaneous MRL/lpr SLE model mice were randomly divided into five groups:model group,Prednisone group,astragaloside Ⅳ group,astragaloside Ⅳ+CHPG[nuclear factor KappaB(NF-κB)pathway activator]group and astragaloside Ⅳ+Nigerian[NOD-like receptor family pyrin domain containing protein 3(NLRP3)activator]group,with eight mice in each group.Eight female MRL/MpJ mice were used as normal group.During the administration,the body mass was weighted.After administration,the spleen,thymus and kidney were weighted,and the organ index was calculated.The 24-hour urinary protein level in urine samples,the biochemical indexes of creatinine(SCr),blood urea nitrogen(BUN),autoantibodies[antinuclear antibody(ANA),anti-double-stranded DNA(dsDNA)antibody,anti-snRNP/Sm antibody]and inflammatory mediators[interleukin(IL)-1β,IL-18]in blood samples were detected.The pathological damage of renal tissue was observed by hematoxylin-eosin(HE)staining,and the fibrosis of renal tissue was observed by Masson staining.The expressions of NF-κB/NLRP3 inflammasome pathway-related proteins in kidney and spleen tissues were detected by Western Blot.Results Compared with the model group,the body mass of mice in prednisone group and astragaloside Ⅳ group increased,the spleen index,thymus index and kidney index were decreased,the serum levels of ANA antibody,anti-dsDNA antibody and anti-snRNP/Sm antibody were decreased,the levels of SCr,BUN and 24-hour urine protein were decreased,the levels of IL-1 βand IL-18 wrere decreased,the ratios of p-p65/p65,p-IKBα/IKBα,cleaved caspase-1/pro caspase-1 and the relative expression of NLRP3 protein in kidney and spleen tissues were decreased(all P＜0.05),and the pathological damage and fibrosis of renal tissue in SLE mice were alleviated,there being no significant difference between the two administration groups(P＞0.05).NF-κB activator and NLRP3 inflammasome activator eliminated the improvement of astragaloside Ⅳ on the above indexes in SLE mice to a certain extent.Conclusion Astragaloside Ⅳ can improve the immune function of SLE mice,reduce renal injury and inflammatory response,and its mechanism may be related to its inhibition of the activation of NF-κB/NLRP3 inflammasome pathway.

OBJECTIVEThe Chinese Children's Leukemia Group (CCLG)-acute lymphoblastic leukemia (ALL) 08 protocol for childhood ALL was established in 2008. This study aims to evaluate the drug-related toxicities of CCLG-ALL 08 protocol in the treatment of childhood ALL.

METHODSA total of 114 children with newly diagnosed ALL were treated with the CCLG-ALL 08 protocol. The protocol was divided into five phases: remission induction (VDLD), early reinforcement (CAM), consolidation therapy, delayed reinforcement (DIa & DIb) and maintenance treatment. Drug-related toxicities in each phase were evaluated according to the Common Terminology Criteria for Adverse Events version 4.0.

RESULTSToxicities were more frequent in phase VDLD than other treatment phases, including hepatotoxicity (87.7%), dental ulcer (20.2%), hyperglycemia (20.2%), prolonged activated partial thromboplastin time (21.1%) and decreased fibrinogen (34.2%), with the incidence rates of severe adverse events at 7%, 0, 1.3%, 0.8% and 2.7% respectively. The incidence of allergic reaction to L-ASP was significantly higher in phase DIa than in phase VDLD (28.0% vs 7.9%; P<0.01), and there were no longer any allergic reactions in 15 patients who received continuing treatment with pegaspargase instead. There was no severe arrhythmia, myocardial ischemia, decreased left ventricular function, osteonecrosis, myopathy, organ failure or treatment-related mortality.

CONCLUSIONSThe drug-related toxicities of CCLG-ALL 08 protocol are common in phase VDLD, but they are mild and reversible. There is no treatment-related mortality. The CCLG-ALL 08 protocol for childhood ALL is safe.

Objective To observe the effect of every-other-day fasting(EODF)on pathology and functional recovery of rats with spinal cord clip-compression injury,and to explore the related mechanism. Methods A total of 36 Sprague-Dawley rats were randomly assigned to groups A(sham operation),B(sham operation and EODF),C(spinal cord injury)and D(spinal cord injury and EODF)with nine rats in each group.The spinal cord injury rat model in T10was established by using medical aneurysm clip in latter two groups.The motor func-tion was assessed by Basso-Beattie-Bresnahan(BBB)score one day before and one day,two,four,six,eight,ten, twelve weeks after operation;and toluidine blue staining was performed for pathological observation at twelve weeks after operation.Another 180 Sprague-Dawley rats were randomly assigned in same way.The level of tu-mor necrosis factor-α(TNF-α)and interleukin-10(IL-10)were detected with ELISA six hours,twelve hours,one day,three days and seven days after operation. Results The BBB score reached lowest on the first day in groups C and D(P<0.05),and gradually increased with time,and were higher in group D than in group C eight weeks,ten weeks and twelve weeks after operation(P<0.05). The pathology in spinal cord was less in group D than in group C.Compared with group A,the level of serum TNF-α increased twelve hours after operation(P<0.05),peaked one day after operation,and returned back seven days after operation;the level of serum IL-10 increased at each time point after operation(P<0.05).Compared with group C,the level of serum TNF-α was lower in group D one day after operation(P<0.05);the level of se-rum IL-10 was not significantly different at each time point after operation(P>0.05). Conclusion Long-term EODF can promote the hind limb motor recovery in rats with spinal cord clip-compression inju-ry,and alleviate pathological damage.EODF might inhibit acute inflammatory reaction at acute stage of spinal cord injury,which may be correlated with its neuroprotective effect.

OBJECTIVETo analyze factors relevant to retarded intellectual development in infants born to mothers with autoimmune disease of thyroid.

METHODSAll the term newborns born to mothers with autoimmune thyroid disease (selection criteria) without asphyxia in all county, city, and provincial hospitals in Zhejiang province (except for Ningbo City) from July 2001 to June 2003 were enrolled through Zhejiang provincial neonatal disease screening network system. The control group was consisted of the neonates who were born to mothers without thyroid disease in these hospitals during the same period. Heel capillary blood samples were collected from the neonates older than 3 days in local hospitals and sent to the center of Zhejiang provincial neonatal disease screening network system. TSH levels were measured by Time Difference Fluorescent Analysis Device (1420 II type, EGG Company, US). If the level of TSH was higher than 9 mU/L, their mothers were called back to the center with their infants within 3 days. If the level of TSH was normal, they were called back to hospitals at age of 28 - 35 days of infants. The pattern of maternal thyroid disease, duration, thyroid function, the history of maternal drug administration, maternal age, gestational age and body weight of the neonates were recorded. The neonatal and maternal serum thyroid function tests were re-performed and the serum TPOAb, TGAb, TRAb and TSAb levels in both neonates and their mothers were measured as well. A 1-year follow-up study was done and all these subjects were investigated by means of Gesell development schedules by special investigators at the age of 1, 3, 6 and 12 months. The results were expressed as developmental quotient. Case-sectional study was performed. Statistical analyses were conducted using SPSS software. The multiple logistic regression analysis was used to analyze factors which might have effect on infantile personal-social ability, adaptive ability, gross motor ability or the fine-motor ability. One-way ANOVA was used to compare those five subfields ability followed by LSD multiple comparisons and Dunnet's C test was used when variances were not equal. Correlation analysis was used to compare the anti-thyroid antibody between neonates and their mothers.

RESULTSPoor personal-social ability, adaptive ability, gross motor ability and fine motor ability of infants born to mothers with autoimmune thyroid diseases were found as compared to the infants born to healthy mothers (P < 0.01). Moreover, the infants born to mothers with Hashimoto's thyroiditis had significantly poorer fine motor ability and adaptive ability than those born to mothers with Grave's disease (P < 0.05). The Spearman correlation coefficients of TPOAb, TGAb, TRAb and TSAb were 0.636, 0.574, 0.619 and 0.473, respectively, and all the P values were lower than 0.01.The multifactor logistic regression analysis showed that infantile TPOAb levels and maternal TRAb levels were associated with infantile personal-social ability, adaptive ability, and gross motor; while maternal TPOAb levels and thyroid function during gestation were associated with infantile fine-motor ability (P < 0.05).

CONCLUSIONMaternal autoimmune thyroid diseases during pregnancy had adverse effects on intellectual development of infants. The maternal levels of TPOAb, TRAb and thyroid status were associated with the infantile personal-social ability, adaptive ability, gross motor and fine motor development. In order to reduce the effect on infant, it is necessary to treat adequately the maternal autoimmune thyroid diseases during pregnancy.
