Objective To explore the locus of control and the relationship with parenting patterns of ado-lescents with first-onset major depressive disorder (MDD). Methods Patients with first-onset MDD (n= 98) and controls (n=98) were investigated by Sphere of Control Questionaire and EMBU, the results were compared and analyzed correlatively. Results The scores of the individual strength scale ( 37.47±13.66) and the relations with people scale ( 38.65±13.19 ) of patients were significantly lower(P<0.05 ) than the controls [(45.39± 12.84) and (45.90±11.20 ) each], while the scores of social-political management (39.01±10.28) were not significantly lower (P>0.05)than the controls' (39.12±9.50). The scores of patients' paternal excessive inter-ference factor(2.66±0.49) , maternal excessive protection/interference (2.79±0.55 ) and rejection/denial fac-tor(2.55±0.39) of EMBU were significantly higher(P<0.05)than controls' [(2.17±0.58),(2.17±0.49) and( 1.75±0.51 ) each]. The scores of patients' paternal affection/understanding factor were significantly posi-tively correlative with patients' scores of relations with people (r=0.27, P<0.05), maternal affection/under-standing factor was significantly positively correlative with patients' scores of individual strength (r=0.21, P <0.05) and relations with people(r=0.23, P<0.05 ) , while maternal excessive interference/excessive protection and individual strength (r=-0.24, P<0.05 ) and relations with people (r=-0.22, P<0.05), maternal rejec-tion/denial and individual strength (r=-0.26, P<0.05) were significantly negatively correlative. Conclusion Adolescents with MDD have abnormal locus of control,which might be correlative with their parenting patterns.

Ampullary cancer is a relatively uncommon cancer,which is often considered to have a best prognosis among periampullary cancers.Preoperative endoscopic uhrasonography and transpapillary intraductal ultrasonography Call provide useful information not only for tumor staging but also for making therapeutic decisions,especially in patients who are appropriate for endoscopic papillectomy.Whipple resection and pylrus preserring panereaticoduodenectomy are considered to be the standard treatment for ampullary cancer.Although transduedenal ampullectomy is regarded as a less-invasive treatment compared with Whipple resection,it has a high morbidity and hish rate of cancer-cell remnant at the resected margin.Endoscopic papiilectomy may be the treatment of choice for selected cases of ampullary cancer. As to unresectable ampullary cancer,the performance of a biliary-enteric bypass is considered routine to solve obstructive ianndice.The decision as to whether to perform gastrojejunostomy in patients without obvious gastroduodenal obstruction secondary to the tumor remains controversial.We believe that prophylactic gastrojejunostomy should be performed routinely when a patient is undergoing surgical palliation for unresectable ampullary cancer.

Objective To study the influence on T-lymphocyte subsets in herpes zoster with adjuvant treatment of compound glycyrrhizin.Methods 93 patients with herpes zoster were randomly divided into two groups:control group(46 cases,treated with antiviral drugs) and 1 treatment group(47 cases,treated with compound glycyrrhizin and antiviral drugs).The expression of T-lymphocyte subsets on the T cell surface in patients and control group were determined by flow cytometry.Results The expression of CD3,CD4,CD8,CD4/CD8 ratio was significantly different in the treatment group and control group.Conclusion Compound glycyrrhizic adjuvant therapy could not only shorten check blister,acetanilide,scar tissue and recovery time,reduce the sequela of neuralgia,but also affect the expression state of T lymphocyte subsets with herpes zoster,improve the cellular immune function with herpes zoster.

Objective To investigate the effects of substance P (SP) pretreatment on the expression of β1-adrenoreceptor(β1-R) induced by norepinephrine (NE) in cultured neonatal rat cardiomyecytes.Methods The cardiomyocytes obtained from 1-3 day old SD rats were cultured for 72 h.The experiment was performed in 2 parts.In part 1 the cells were seeded in 15 well plate and randomly divided into 5 groups (n=3 wells each):control group (C1)and 4 NE groups were exposed to NE 10-9, 10-8,10-7,10-6 mol/L respectively (NE1,2,3,4).In part Ⅱ the.cells were seeded in 12 well plate and randomly divided into 4 groups (n=3 wells each): group I control (C2): group II NE 10-7 tool/L; group Ⅲ (SN)was pretreated with SP 10-6 mol/L 30 minbefore NE 10-7 mol/L and group IV (NSN)was treated with NK-1 receptor antagonist (NK-1 tachykinin receptor antagonist,S3144) 30 min before SP pretreatment.After exposure to NE for 3 h the expression of β1-R in the rat cardiomyecytes was detected using flow cytometry.Results In part Ⅰ the expression of β1-R was significantly higher in group NE1-3 than in control group (C1),with the highest expression in group NF3.In part Ⅱ the expression of β1-R was significantly higher in group Ⅱ (NE) than in control group (C2) while lower in group Ⅲ (SN) than in control group Ⅱ.(NE).There was no significant difference in the expression of β1-R between group Ⅰ (C2) and group Ⅲ and Ⅳ (NSN).Conclusion Substance P pretreatment can inhibit the up-regulation of β1-R expression in cultured rat cardiomyocytes induced by norepinephrine through activating NK-1 receptor.

Radioactive 125I interstitial brachytherapy is easy to cause the intestinal tract tissue damage.Its mechanism possibly correlates to the quick renewal speed of the intestinal tract tissue and a majority of ceils in M, G2 and late S phases. The tolerant dose of intestinal tract tissue is approximately 160 Gy. If the absorbed dose is higher than the tolerant one, the intestinal tract tissue will be damaged. In the clinical practice of radio-active 125I interstitial brachytherapy, through the strict plan of the TPS system before the operation, by using ul-trasound, CT, MR/and other imaging technologies in the operating process and establishing the suitable barrier protection between the seeds and intestinal tract tissue, the radioactive damage of the intestinal tract tissue my be reduced.

There are three systems to protect the geographical indications of genuine medical materials in present China, which easily leads to the right-conflicts among several geographical indications rights. The situation is not reasonable, but is legitimate in the current legal system. So we should start from the present legislation and learn from foreign experience to resolve it step by step. To be specific, in the short term, we should strengthen propaganda and alter the existing logos to reduce the possibility of consumer confusion. Meanwhile, we should annul or revoke the registration of the improperly registered geographical indications. In the medium term, we should make some amendments to the legislation, that is, to give priorities to geographical indication products. At last, we should change the three systems into a single protection mode on the basis of the geographical indication products system.

Objective To prepare an internal quality control substance of free hemoglobin (FHb),and evaluate its perform-ance.Methods ① 5 normal whole human blood samples with known hemoglobin (Hb)concentration was selected and dilu-ted with distilled water in the ratio of 1∶500,1∶1 000,1∶2 000,1∶4 000 respectively.After 20 FHb solutions was fully mixed,the concentration of FHb solutions was tested and compared with its theoretical data.②One of the highest value and the lowest value solutions were chosen as qualitye control substance,packed and stored in -20℃ fridge.Each group was an-alyzed 20 days continuously in the routine conditions,where average (-x )of the groups,standards deviation (s )and coeffi-cients of variation (CV)were calculated and Levey-Jennings control chart was conducted.Then,the test was repeated every week,and the data on the chart was updated accordingly until (CV)of the reagents were changed.The average (-x)of the-groups,standards deviation (s)and coefficients of variation uality control material was calculated during the whole test peri-od.Results ①The theoretical value (-x ±s)of the concentration of free hemoglobin was 125.44±93.04 mg/L,and the actu-al value was 125.22±93.08 mg/L,there was no statistic significance (t value was 0.706,P >0.05).② During 20 continu-ously daystest,the detected values (-x ±s)of the highest quality control material was 303.55±3.70 mg/L;the values of the lowest quality control material was 69.29 ± 1.88 mg/L.The coefficients were 1.22% and 2.68% respectively.Both the highest and the lowest quality control material were under control during the whole detecting period.The (-x ±s )values of the highest was 302.56±3.99 mg/L,the CV value of it was 1.32%;The (-x ±s)values of the lowest was 69.04±1.88 mg/L,the CV value of it was 2.71%.Conclusion The preparation method of internal quality control substance of free hemoglo-bin is convenient and stable,and was applicable in blood station’s and clinical laboratory.
