Background and purpose: L-asparaginase (L-Asp) is an important drug in the treatment of childhood lymphoid neoplasms at present, but a lot of adverse reactions of L-Asp were observed. Pegasparaginase (PEG-Asp) is available in China in recent years. This study aimed to explore efifcacy and side-effect of PEG-Asp as ifrst-line treatment in childhood acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). Methods:A total number of 211 ALL or LBL patients were treated with CCLG 2008 or BFM-90 protocol with PEG-Asp or L-Asp between Apr. 2008 and Mar. 2013;42 patients, among whom, were 35 ALL patients and 7 LBL patients, were treated with PEG-Asp as ifrst-line treatment;169 patients were treated with L-Asp as ifrst-line treatment (including 53 patients treated with L-Asp during induction protocol; with PEG-Asp during consolidate protocol). The clinical outcome and adverse reaction of PEG-Asp with L-Asp were observe and compared. Results: There were 35 ALL patients in PEG-Asp ifrst-line treatment group and the complete remission rate after 1 course of PEG-Asp was 97.1%,however, which was 83.3%of high risk ALL patients. The complete remission rate of 7 LBL patients of PEG-Asp ifrst-line treatment group was 57.1%. There was no signiifcant difference between 2 groups (P>0.05). Thirty-four patients relapsed including 5 patients of PEG-Asp ifrst-line treatment group, 16 patients of L-Asp ifrst-line treatment group and 13 patients treated with L-Asp during induction protocol and with PEG-Asp during consolidate protocol. Thirty-one patients died including 3, 18, 10 patients in 3 groups respectively. Twenty-two patients died of relapse, 4 died without remission, 5 died of complications. There was also no signiifcant difference between 2 groups (P>0.05). The incidence rates of adverse reactions were 47.6% and 63.3% respectively. Anaphylaxis, liver functions abnormalities, blood coagulation abnormalities, gastrointestinal reaction, hyperglycemia and pancreatitis were common in our patients. The incidence rate of anaphylaxis in PEG-Asp as ifrst-line treatment group was lower than other groups (P=0.03). But there was no signiifcant difference been observed in the incidence of other adverse reaction. Conclusion: The short-term efifcacy of PEG-Asp as the ifrst-line treatment in childhood leukemia and lymphoma was satisfactory and the incidence rate of anaphylaxis was lower. However, we will still pay much attention to adverse reaction monitoring of PEG-Asp.

OBJECTIVE: We wanted to evaluate the image quality and diagnostic value of 64-slice dual-source computed tomography (DSCT) coronary angiography in patients with atrial fibrillation (Afib). MATERIALS AND METHODS: The coronary arteries of 22 Afib patients seen on DSCT were classified into 15 segments and the imaging quality (excellent, good, moderate and poor) and significant stenoses (> or = 50%) were evaluated by two radiologists who were blinded to the conventional coronary angiography (CAG) results. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for detecting important coronary artery stenosis were calculated. McNemar test was used to determine any significant difference between DSCT and CAG, and Cohen's Kappa statistics were calculated for the intermodality and interobserver agreement. RESULTS: The mean heart rate was 89 +/- 8.3 bpm (range: 80-118 bpm). A range from 250 msec to 300 msec within the RR interval was the optimal reconstruction interval for the patients with Afib. The respective overall sensitivity, specificity, PPV and NPV values were 74%, 97%, 81% and 96% for reader 1 and 72%, 98%, 85% and 96% for reader 2. No significant difference between DSCT and CAG was found for detecting a significant stenosis (reader 1, p = 1.0; reader 2, p = 0.727). Cohen's Kappa statistics demonstrated good intermodality and interobserver agreement. CONCLUSION: 64-slice DSCT coronary angiography provides good image quality in patients with atrial fibrillation without the need for controlling the heart rate. DSCT can be used for ruling out significant stenosis in patients with atrial fibrillation with its high NPV for detecting in important stenosis.

OBJECTIVETo introduce the procedure of the 1st ray stabilization combined with resection of the lesser metatarsal heads for patient with severe forefoot deformity caused by rheumatoid arthritis (RA) and evaluate the short to mid-term clinical results.

METHODSFrom Oct. 2006 to Aug. 2010,97 patients (129 feet) aged from 36 to 67 years (average 54), with forefoot deformity caused by rheumatoid arthritis were reviwed. There were 88 males and 9 females,65 single lateral involved and 32 bilateral involved, the average duration of disease was 17 years (6 to 32 years). The 1st ray instability and lesser metatarsophalangeal (MTP) joint stiff dislocation were found in all cases. The first ray stabilization combined with resection of the lesser metatarsal head procedure were performed for all cases. The radiographic Hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measurde and the JSSF (Japanese Society for Surgery of the Foot) score were evaluated before operation and every follow up.

RESULTSThe average followed-up was 37 months (6 to 52 months) for all patients except 5 (7 feet) and 1 died for acute cardiac infarction 1 year after operation. The average JSSF score improved from (33.2 +/- 8.2) points preoperative to (67.3 +/- 3.1) points at final followed-up (P < 0.01); the average HVA was corrected from (50.0 +/- 11.8) degrees preoperative to (21.2 +/- 3.2) degrees at final follow up (P < 0.01); the average IMA was corrected from (15.5 +/- 3.6) degrees preoperative to (9.7 +/- 6.6) degrees at final follow up (P < 0.01). MTP joint nonunion was found in 4 feet. A radiographic high density mass was found in the 1st cuneiform bone during 8 to 11 months followed-up in 3 feet; delayed wound healing was happened in 9 feet; MTP joint infection was happened in 2 feet; tarsometatarsal joint infection was happened in 1 foot; lesser MTP joints deformity recurrence were found in 16 feet.

CONCLUSIONThe characters of forefoot with RA in later stage are the 1st ray deformity and instability compound with the lesser toes deformity. The 1st ray stability procedure which include the 1st MTP arthrodesis and the Lapidus procedure can correct the 1st ray deformities and rebuilt its stability. The lesser toes metatarsal head resection is effective in correct their deformity. This combined procedure is reliable. It is suitable for patients with severe Hallux valgus, increased IMA, tarsometatarsal joint instability and the lesser MTP joint stiff dislocation.

OBJECTIVETo explore the effects of mitogen activated protein kinase (MAPK) and extracellular signal-regulated kinases (ERK) on kidney injury in female BALB/c mice exposed to cadmium.

METHODTwenty-one female BALB/c mice were randomly divided into 3 groups, i.e. control group, low Cd exposure group (2.5 µmol/kg) and high Cd exposure group (10 µmol/kg) were exposed to normal saline, 2.5, 10 µmol/kg Cd, respectively, 3 times a week for 14 weeks. The kidney slice were stained by HE, PAS and Masson staining to observe the morphological changes. The expression levels of pERK, ERK, pp38, p38, pJNK and JNK proteins in kidneys were tested by Western blot assay.

RESULTSThe ratios of pERK/ERK, pp38/p38, pJNK/JNK in high Cd group were higher than those in the control group (P < 0.05). The ratio of pERK/ERK in low Cd group was higher than control group (P < 0.05). The expression levels of bcl-2, bax proteins and the ratio of bcl-2 to bax in Cd exposure groups decreased significantly, as compared with the control group (P < 0.05). The impairment of renal glomeruli and tubules were observed in HE, PAS and Masson staining slices of kidneys in mice exposed to Cd.

CONCLUSIONCdCl2 may induced renal injury by affecting the expression levels of MAPK.

OBJECTIVETo explore the comprehensive program of integrated Chinese and western medicine in the treatment of cognitive impairment in earthquake brain injury.

METHODSThe multi-central randomized controlled trial was adopted. The qualified subjects were randomized into an acupuncture + rehabilitation group (38 cases) and a rehabilitation group (35 cases). In the acupuncture + rehabilitation group, acupuncture, hyperbaric oxygen (HBO) and cognitive rehabilitation training were combined as the comprehensive program of integrated Chinese and western medicine in the treatment. In the rehabilitation group, HBO and cognitive rehabilitation training were adopted. The efficacy and safety were assessed.

RESULTS(1) After treatment of 2 months, the intelligent state, cognitive function and activity of daily life of patients were improved in the both groups (all P < 0.01). (2) After treatment of 2 months, the score of MMSE and the score of activity of daily life were (24.11 +/- 4.08) and (75.45 +/- 13.95) in the acupuncture + rehabilitation group, which were more significant as compared with (17.05 +/- 43.84), (66.06 +/- 12.75) in the rehabilitation group, respectively (both P < 0.01). In 6-month follow-up visit after treatment, the cognitive function and activity of daily life were improved continuously in the acupuncture + rehabilitation group, which was more significant as compared with the rehabilitation group (P < 0.01, P < 0.05).

CONCLUSIONThe integrated Chinese and western medicine of acupuncture, HBO and cognitive rehabilitation training is safe and effective in the treatment of cognitive impairment in earthquake brain injury. The therapeutic effect is more advantageous as compared with the simple rehabilitation program of western medicine.

UNLABELLEDOCTOBER: To explore the effects of the glucagon-like peptide 1 (GLP-1) liraglutide on the penile erectile function of rats with diabetic erectile dysfunction (DED) by observing the impact of liraglutide on the expression of eNOS in the corpus cavernosum of diabetic rats.

METHODSWe randomly divided 30 six-week-old male SD rats into a normal control (n = 10) and an experimental group (n = 20) , established models of diabetes mellitus (DM) in the experimental rats, and subdivided them into a DM (n = 8) and a GLP-1 group (n = 8) to receive intramuscular injection of normal saline and liraglutide at 5 mg per kg of the body weight per day, respectively. After 12 weeks of intervention, we obtained the levels of FPG, FINS, TG, TC, HDL-C, LDL-C, testosterone, and IL-6 and the indexes of Homa-IR and Homa-β, detected the expressions of Akt/p-Akt and eNOS/p-eNOS in the corpus cavernosum by Western blot, and compared the erectile function between different groups.

RESULTSThe frequency and rate of penile erection were significantly lower in the DM group than in the GLP-1 and normal control groups (P < 0.05) and also lower in the GLP-1 group than in the normal controls (P < 0.05). Immunofluorescence staining showed the expression of eNOS mainly in the cytoplasm of the cavernosal vessels and sinusoidal endothelial cells, markedly lower in the DM and GLP-1 groups than in the normal rats (P < 0.05), but higher in the GLP-1 than in the DM group (P < 0.05). The level of eNOS/p-eNOS in the penile tissue was significantly decreased in the DM and GLP-1 groups in comparison with the normal controls (P < 0.01 or P < 0.05), while that of p-eNOS was markedly increased in the GLP-1 group as compared with the DM group (P < 0.05). No statistically significant differences were observed in the Akt level among the three groups of animals (P > 0.05). The expression of p-Akt was remarkably reduced in the DM and GLP-1 groups in comparison with the control rats (P < 0.01 or P < 0.05), but higher in the GLP-1 than in the DM group (P < 0.05).

CONCLUSIONGLP-1 can protect the function of endothelial cells in the corpus cavernosum and improve the erectile function of DED rats by regulating the Akt/ eNOS signaling pathway, which indicates that GLP-1 could be an important option for the treatment and prevention of DED.

Objective To investigate the distribution and characteristics of iodine excess areas in Liaocheng City of Shandong Province, and to provide data evidence for taking intervention measures. Methods From 2011 to 2013, 1 - 3 samples of drinking water were collected from all administrative villages in 8 counties (cities and districts) of Liaocheng.At the same time,1 sample of edible salt was collected from the household where water samples were collected. Arsenic and cerium spectrophotometry was used for the detection of water iodine and salt iodine was detected by semi-quantitative method. The region were divide according to the definition of "Water Source Excess Iodine Area and Excess Iodine Disease Area"(GB/T 19380-2016)and"Division of Iodine Deficiency Disorders Area"(GB 16005-2009).Results A total of 7 794 water samples were collected in 5 865 villages of 134 towns and the iodine median was 158.2 μg/L. The median of water iodine of 57 samples was less than 10 μg/L in drinking water and the ratio was 0.7%;2 286 samples were 10- 100 μg/L and the ratio was 29.3%; 5 451 samples were over 100 μg/L and the ratio was 69.9%. The towns with suitable water iodine (10 - 100 μg/L) and high water iodine ( > 100 μg/L) were 24.6%(33/134)and 75.4%(101/134), respectively, and no iodine deficiency town was found. The areas with high water iodine were distributed in patchy or foci. A total of 3 300 salt samples were collected,among them,iodized salt was 1 183(35.58%,1 183/3 300)and non-iodized salt was 2 117(64.15%,2 117/3 300). Among them, there were 36 towns with high iodine content and 20 towns with suitable iodine content, and the iodized salt coverage rates were 10.72% (225/2 099) and 79.77% (958/1 201),respectively.Conclusions The population of Liaocheng City is at risk of iodine excess.The high iodine areas coexists with suitable iodine areas.
