Objective To study the salt intake of patients undergoing maintenance hemodialysis and explore their knowledge and behaviour. Methods The patients undergoing maintenance hemodialysis were offered salt spoon and soy sauce cup. Their diaries on home meals for 3 consecutive days were collected to calculate their salt intake. Meanwhile, a one to one interview was done to evaluate the accuracy of patient′s diet diary and the knowledge and behavior of low salt diet and find out related factors of salt intake. Results The average salt intake was (6.49 ± 1.64)g/d. The average composition rate in the low salt diet knowledge in low salt diet behavior was 51.00% and 47.00% respectively. Age and education level were the influencing factors of salt intake. Conclusions The average salt intake is much higher than the standard for the patients undergoing maintenance hemodialysis. Their low salt diet knowledge is in the middle level and their low salt diet behavior is in the middle or lower level. The related factors include age and education among patients undergoing maintenance hemodialysis.

BACKGROUND: Animal experiments showed that recruitment maneuver (RM) and protective ventilation strategy of the lung could improve oxygenation and reduce extravascular lung water. This study was to investigate the effects of RM on respiratory mechanics and extravascular lung water index ( EVLWI) in patients with acute respiratory distress syndrome (ARDS). METHODS: Thirty patients with ARDS were randomized into a RM group and a non-RM group. In the RM group, after basic mechanical ventilation stabilized for 30 minutes, RM was performed and repeated once every 12 hours for 3 days. In the non-RM group, lung protective strategy was conducted without RM. Oxygenation index (PaO2/FiO2), peak inspiratory pressure (PIP), Plateau pressure (Pplat), static pulmonary compliance (Cst) and EVLWI of patients before treatment and at 12, 24, 48, 72 hours after the treatment were measured and compared between the groups. Hemodynamic changes were observed before and after RM. One-way ANOVA, Student's t test and Fisher's exact test were used to process the data. RESULTS: The levels of PaO2/FiO2 and Cst increased after treatment in the two groups, but they were higher in the RM group than in the non-RM group (P<0.05). The PIP and Pplat decreased after treatment in the two groups, but they were lower in the RM group than in the non-RM group (P<0.05). The EVLWI in the two groups showed downward trend after treatment (P<0.05), and the differences were signifcant at all time points (P<0.01); the EVLWI in the RM group was lower than that in the non-RM group at 12, 24, 48 and 72 hours (P<0.05 or P<0.01). Compared with pre-RM, hemodynamics changes during RM were significantly different (P<0.01); compared with pre-RM, the changes were not significantly different at 120 seconds after the end of RM (P>0.05). CONCLUSIONS: RM could reduce EVLWI, increase oxygenation and lung compliance. The effect of RM on hemodynamics was transient.

Aim To explore the effect of knockdown spinal cord LCN2 by RNAi on the development of mor-phine tolerance in normal rats.Methods After suc-cessful intrathecal implantation, fourty-eight male Sprague-Dawley rats weighing 1 80 -220 grams were randomly divided into 4 groups (n =1 2):group I:control group,group II:morphine tolerance group, group Ⅲ:mismatch siRNA group,group IV:LCN2 siRNA group.The sixth day after intrathecal implanta-tion,rats were tested to ensure the position of cathe-ters,and it was recorded as d 0.On d 2 -8,rats were subcutaneously (s.c)injected of normal saline (NS) (group I)or morphine (group Ⅱ,Ⅲ,Ⅳ)1 0 μg· g -1 twice a day at 8:00 and 1 6:00.Before everyday s. c injection,rats were intrathecally injected of 1 0 μL DEPC solution (group Ⅰ,Ⅱ),1 0 μL DEPC solution containing 4 μg mismatch siRNA (group III)and 4 μg LCN2 siRNA solution (group IV).Paw withdrawal la-tencies to thermal stimuli (PWTL)were tested before morphine injection and 45 minutes after morphine in-jection on d 1 and d 9.The percentage of maximal pos-sible effect (% MPE)was calculated later.Animals were sacrificed on d 9 after the behavioral test and the lumbar enlargement segments of the spinal cord were removed for detecting the expression of phosphorylated-p38 mitogen-activated protein kinase (p-p38 MAPK) and LCN2 by Western blot and microglia marker Iba1 by immunofluorecence.Results On d 1 ,there was no significant difference in %MPE among four groups. On d 9,compared to group Ⅰ,%MPE was signifi-cantly reduced (P <0.05)while p-p38MAPK,LCN2 and Iba1 were markedly up-regulated in group Ⅱ andⅢ (P <0.05 ).On d 9,compared to group Ⅱ,%MPE was significantly increased while p-p38MAPK, LCN2 and Iba1 were markedly reduced in group IV (P<0.05).Conclusion Using LCN2 siRNA to knock-down spinal LCN2 relieves the development of mor-phine tolerance in normal rats possibly through inhibi-ting the activation of microglia and p38 MAPK in the spinal cord.

OBJECTIVETo observe clinical effect of integrated Chinese medical (CM) treatment (as maintenance therapy) on the progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small-cell lung cancer (NSCLC) after first-line chemotherapy.

METHODSThe study was a prospective, randomized, controlled clinical trial. Totally 69 non-progressive advanced NSCLC patients treated with first-line chemotherapy were randomly assigned to the test group (34 cases) and the control group (35 cases). Patients in the control group were treated with one Western drug chemotherapy (Gemcitabine or Alimta or docetaxel). Those in the test group were treated with integrated CM treatment (CM decoction, CM Intravenous preparation, and point application). Each cycle consisted of 21 days. Treatment lasted till the disease progressed, or intolerable toxic/adverse reactions occurred, or patients refused to continue the treatment. Patients' life spans were regularly followed-up.

RESULTS(1) The median cycle of maintenance therapy was 2 cycles for two groups with no statistical difference (P =0.274). The median PFS was 12.43 weeks in the test group and 10.00 weeks in the control group, showing statistical difference (P =0.025). The middle survival time (MST) was 18.8 months in the test group and 16.73 months in the control group, showing no statistical difference (P =0.437).

CONCLUSIONCM treatment (as maintenance therapy) showed quail effect to one Western drug chemotherapy in prolonging patients' life span.

OBJECTIVETo investigate the prevalence and possible influencing factors of depressive disorder in surgical inpatients.

METHODSTwo hundred and sixty-six surgical inpatients meeting the inclusion criteria were first screened with the self rating depression scale (SDS), and then the subjects screened positive and 20% of those screened negative were evaluated with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) as a gold standard for diagnosis of depressive disorder. Possible influencing factors were also analyzed by experienced psychiatrists.

RESULTSThe standard score of SDS in the surgical inpatients were significantly higher than those in the Chinese norm, and the incidence of depressive disorder in the surgical inpatients was 37.2%. Unvaried analysis showed that depressive disorder were associated with gender, education, economic condition, variety of diseases, hospitalization duration, and treatment methods. Logistic regression analysis revealed that gender, economic condition, treatment methods and previous history were the main influencing factors.

CONCLUSIONSThe incidence of depressive disorder in the surgical inpatients is high, and it is mainly influenced by gender, economic condition, treatment methods and previous history.

ObjectiveTo explore the relations between the alkaline phosphatase(ALP) and the type of cerebral palsy. MethodsThe ALP level of 40 children with different types of cerebral palsy were examined with the Olympus AU-600 apparatus. ResultsThe ALP value of the children with spastic cerebral palsy is normal. The ALP value of the children with athetoid cerebral palsy is higher than spastic cerebral palsy(P<0.001).Conclusions The ALP value can help us to identify the type of cerebral palsy.

OBJECTIVETo explore the differences of electroacupuncture (EA) on onset time and symptom improvement for treatment of different types of functional constipation.

METHODSThirty-eight cases of constipation were selected, including 9 cases of constipation-predominant irritable bowel syndrome (IBS-C), 10 cases of slow transit constipation (STC), 10 cases of pelvic floor dyssynergia (PFD) and 9 cases of inadequate defecatory propulsion (IDP). The electroacupuncture was applied at Tianshu (ST 25), Fujie (SP 14), Shenshu (BL 23), Dachangshu (BL 25) and so on in abdominal and lumbosacral area, 5 times per week, 10 times as a treatment course. The onset time, score of clinical symptoms of constipation and improvement of every symptom in each group were compared.

RESULTS(1) The onset time was (1.78 +/- 0.83) days in IBS-C type, (3.11 +/- 1.90) days in IDP type, (4.10 +/- 1.85) days in STC type and (4.30 +/- 2.00) days in PFD type, indicating statistical differences between IBS-C type and STC type, IBS-C type and PFD type (both P < 0.05). (2) Compared before the treatment, the total scores of symptoms on the onset day in each group were all improved (P < 0.05, P < 0.01), and score of IBS-C type was superior to the rest 3 types (P < 0.05, P < 0.01). (3) EA improved desire to defecate or frequency of defecation in each type (P < 0.05, P < 0.01), in which both were improved in STC type and PFD type, and the improvement of defecation frequency was more significant in STC type (P < 0.01). EA relieved unsmooth defecation or pendant-expansion feeling in each type (all P < 0.05), in which both were improved in IBS-C type (both P < 0.05). EA relieved abdominal distension and pain in IBS-C type, STC type and PFD type (all P < 0.05), while its effects were not obvious on defecation difficulty, defecation time and defecation texture (all P > 0.05).

CONCLUSIONThe electroacupuncture for treatment of 4 types of constipation is characterized by rapid onset; the improved symptoms are not identical in the electroacupuncture treatment plan for each type of defecation; the main improvement of symptoms are lied on desire to defecate and frequency of defecation, unsmooth defecation or pendant-expansion feeling and abdominal distension and pain. Meanwhile the improvements of defecation texture, defecation difficulty and defecation time were not signi-ficant.

A 10-month-old boy suspected of genetic abnormality was admitted for fever and coughing. Routine G-banding chromosome analysis of the peripheral blood lymphocytes and hereditary pattern analysis on the basis of the karyotypes and disease history revealed that the karyotype of the boy's mother was 46, XX,t(4;9)(q31;p24), and that of the boy was XY,der(9)t(4;9)(q31;p24)mat. The mother was identified as a carrier of balanced translocation of the chromosome who gave the abnormal chromosome 9 to her son, and she had only a chance of 1:18 to have a normal offspring. This case reiterates the importance of antemarital examination and prenatal diagnosis for preventing chromosomal diseases.
