ObjectiveTo study the relationship between depression and physical self and related factors of head and neck cancer patients (HNCPs).MethodsOne hundred and twenty-eight HNCPs were assessed with self-rating depression scale,physical self scale,negative physical self scale and symptom checklist-90 (SCL-90).SPSS 16.0 was used to analyze the data.ResultsThe evaluation of appearance,sport characters and figure characters were significantly different between sexual groups,the average physical self scale level of the male patients was higher than that of the females (3.33 ± 0.56 vs.2.87 ± 0.32,P ＜ 0.05).The appearance,sport characters,figure characters and sexual characters of physical self-concept were significantly different between age groups,the body satisfaction scale from higher to lower were under 45 years old patients,beyond 60 years old,between 46 and 59 years old.ConclusionThe evaluation of appearance is reversely correlated with the score of SCL-90,the evaluation of short,appearance and fat in negative physical self are positively correlated with the score of SCL-90.

Objective To study the roles of apoptosis genes bcl 2, bax, and bak in the pathogenesis of hepatitis D. Methods Expressions of HDAg, bcl 2, bax, and bak in liver specimens of 77 patients with hepatitis D were studied by immunohistochemical method. Meanwhile, the relationship of HDAg expression with the expressions of bcl 2, bax, and bak was studied by double labelling. Results Bcl 2 was mainly expressed in the cytoplasm of hepatocytes, and bax and bak mainly in the cytoplasm of hepatocytes and partly in the nucleus of hepatocytes, and HDAg mainly in the nucleus of hepatocytes. Lots of HDAg and bax/bak positive cells were distributed in infiltrating lymphocytes at the periportal region especially at the advancing edges of areas of piecemeal necrosis. Apoptosis of many hepatocytes was found to locate near the HDAg positive cells. There was positive correlation between the expression of bax/bak and HDAg expression ( P

Objective To analyze the clinical and CT manifestations of the chest and abdomen lymphangioleiomyomatosis (LAM). Methods The clinical and CT manifestations of 13 patients with LAM proved histopathologically were reviewed retrospectively.Results Twelve patients onset with intrapulmonary manifestations all had progressive dyspnea, other symptoms included pneumothorax of recurrent attacks, chest distress, hemoptysis, cough, chylothorax and so on. During the course of disease, 12 patients had no extrapulmonary symptoms, abdominal great goiter was found unintentionally in the rest one without any intrapulmonary symptoms. Pectoral CT manifestations included sporadic or asystematic cysts in pulmones with size of 2-20 mm, and most had thin and clear capsule wall. The lung parenchyma among cysts was mostly normal. Four patients had pneumatocele, 2 had pleural effusion. Abdominal CT was performed in 10 patients and 7 had abnormal findings: renal angiolipoleiomyoma (ALL) in 3 including one had retroperitoneal multiple lymphangiomyomas and effussion and seroperitoneum, another 2 had multiple liver ALL and spleen accretion. The rest 4 patients included retroperitoneal lymphadenectasis in 2, seroperitoneum in one, as well as retroperitoneal lump and spleen accretion in one patient.Conclusion Pectoral and abdominal symptoms in LAM are not specific, but the CT manifestations somehow specific, which are helpful to the identification and early diagnosis of LAM.

OBJECTIVE:To study the ADR mechanism of conjunctival hyperemia in model rats with prostacyclin-induced high intraocular pressure. METHODS:50 rats were randomly divided into normal control group,model group,prostacyclin low-dose, medium-dose,high-dose groups(100,200,400 mg/kg),10 in each group. Except for normal control group,right eyes of rats in other groups were established high intraocular pressure model,dropping corresponding medicine once a day,for 1 week. After last administration,the right eyes cornel peripheral corneal endothelial cells of rats in each group were isolated in vitro and cultured. Vascular endothelial cell viability,cell apoptosis and proliferation-related factor(Ki-76),apoptosis-related factors(Bad,Bax),in-hibito of apoptosis-related factors (Bcl-2,Bcl-xl) protein expressions were detected. RESULTS:Compared with normal control group,vascular endothelial cell viability in model group were obviously decreased;apoptosis rate was obviously increased;Bad, Bax protein expressions were obviously enhanced;Bcl-2,Bcl-xl,Ki-76 protein expressions were obviously weakened,with statisti-cal significances (P<0.05 or P<0.01). Compared with model group,vascular endothelial cell viability in prostacyclin low-dose,medium-dose,high-dose groups were obviously decreased;apoptosis rate was obviously increased;Bcl-2,Bcl-xl protein expres-sions were obviously weakened,with statistical significances(P<0.05 or P<0.01);the Bad,Bax protein expressions in prostacy-clin medium-dose,high-dose groups were obviously enhanced(P<0.05 or P<0.01),the other indexes had no statistical differenc-es(P>0.05). CONCLUSIONS:Prostacyclin may cause conjunctival hyperemia through promoting the apoptosis of cornel peripher-al corneal endothelial cells of model rats with high intraocular pressure and decreasing the cell viability.

ObjectTo develop the reliable RP-HPLC methods for the determination of salidroside, tyrosol, rosavin, rosin, and rosarin in the plants of Rhodiola L. and to evaluate their species from different habitats. Methods Method Ⅰ: methanol-water (0.5 mmol/L SDS in 1% acetic acid aqueous solution) system for the analysis of salidroside; method Ⅱ: acetonitrile-water system for rosavin; method Ⅲ: aqueous acetonitrile-phosphoric gradient system for salidroside, tyrosol, rosavin, rosin, and rosarin. Results The contents of salidroside in different species range from 0.021% to 1.420%, and those of rosavin in all species are very limited or undetected except in Rhodiola rosea L. and R. sachalinensis. The contents of the five marker ingredients are significantly species- and habitat-dependent. Conclusion Three RP-HPLC methods are established for quantitative analysis of the above five marker ingredients in the meantime, respectively. Evaluation of the quality of varied species of Rhodiola L. shows that R. rosea growing in Xinjiang Uygur Autonomous Region and R. sachalinensis growing in Jilin province are the two better species contained with abundant above-mentioned ingredients in China.

Objective To discuss the experiences of management of female duplicated kidney with urinary incontinence. Methods The clinical data of 25 cases with duplicated kidney with urinary incontinence were retrospectively analyzed. They were all female, age ranged from 2 to 12 years old, averaging 7. Fifteen cases were with right side lesions, 10 with left side. The main complaint was urinary incontinence and itching of pudendum. The diagnosis was set up by physical examinations and imaging methods. Results Twenty-five cases reported continent after operation. For the patients taken ureteral replant, the upper kidney function kept or recovered during follow-up. Conclusions Sonography, IVU, and MRU play an important part in the diagnosis of duplicated kidney with urinary incontinence. Operation is the key treatment for this disease.

Objective To discuss the influence of motor imagery therapy on the recovery of the stroke patients with aphasia.Methods Sixty cases of stroke patients with aphasia were divided into the treatment group and the control group according to the odd and even of last number.The single number was set into the control group.The double number was given to the treatment group.There were thirty patients in each group.Both groups received the conventional drug treatment and routine care of the Department of Neurology.On this basis,from the second day in hospital,the treatment group received the speech rehabili tation training with motor imagery therapy.Aphasia assessment was done for the two groups on the first day in hospital with CRRCAE.On the first day and after receiving ten-day treatment with motor imagery therapy,the grade of the severity for aphasia of Boston Diagnostic Aphasia Examination (BDAE) was done to assess the severity of aphasia in two groups.The scores of the two groups were compared.Results Before the treatment,there was no significant difference between the two groups.After receiving ten times treatment,both the two groups were improved.Compared with the control group,the treatment group became better.There was statistically significant difference between the two groups.Conclusions For the stroke patients with aphasia,motor imagery therapy has significant effect on their recovery.

Objective To retrospectively review the efficacy of large craniotomy with subtemporal decompression in the treatment of severe craniocerebral injury combined with cerebral infarction.Methods Forty-eight patients suffering from severe craniocerebral injury combined with cerebral infarction were randomized into the treatment group (managed by large craniotomy decompression) and the control group (managed by clearance of hematoma by routine craniotomy ).A retrospective analysis was carried out to compare the cerebral infarction size between the two groups before operation and at day 1 and 1 week after operation and the outcomes of the two corresponding groups three months post-operatively.Results The infarction size of the treatment group was insignificant in comparison with that of the control group pre-operatively and at day 1 post-operatively,but was significantly smaller than that of the control group one week post-operatively (P ＜ 0.05 ).The mortality and moderate disability/good rate of the treatment and control groups presented significant differences three months post-operatively (21％,42％ vs 33％,25％ respectively,P ＜ 0.05 ).Conclusion Large craniotomy decompression is effective in treating severe craniocerebral injury combined with cerebral infarction and plays an important role in reducing disability and mortality.

ObjectiveTo observe the early changes of N-methyl-D-aspartic acid (NMDA) receptor subunit NR1 and NR2B expressions in the hypothalamus so as to discuss the underlying mechanism of the excitability alternation of hypothalamus-pituitary-adrenal (HPA) axis following severe burn in rats.MethodsA total of 40 Sprague-Dawley rats were randomized into the control group and the experimental groups ( including 6,24 and 48 hours after burn) and a 30％ total body surface area full-thickness burn was induced by immersing the shaved dorsum into boiling water for 40 s.Then,the expression changes of the NMDA receptor subunits NR1 and NR2B in the hypothalamus tissue were examined by using immunohistochemistry and Western blot.Results There was an obvious enhancement of the excitability of HPA axis and obvious changes of serum concentration of cortisol and hemodynamics.The serum concentrations of cortisol of the experimental groups reached the peak at 6 hour after burn and were significantly higher than the control group even 48 hours later (P ＜ 0.05 ).Systolic pressure (SP),diastolic pressure (DP) and left ventricular systolic pressure (LVSP) of the experimental groups were all decreased at 6 hours after burn,of which SP and DP were still lower than the control group at 48 hours after burn (P ＜0.05).Based on the Western blot assay,the NR1 level was increased and reached the peak (1.12 ±0.27) in the experimental groups and 0.45 -±0.15 in the control group at 24 hours after burn (P ＜ 0.05).In the meantime,the NR2B level was decreased significantly and reached the lowest for 0.65 ±0.21 at 6 hours after burn,with statistical difference in comparison with 1.38 ±0.51 in the control group (P ＜0.05.The NR2B level recovered to pre-burn level for 1.25 ±0.30 at 48 hours in the experimental groups,with no statistical difference compared with 1.38 ± 0.51 in the control group (P ＞ 0.05 ).The immunohistochemistry results on hypothalamus paraventricular nucleus (PVN) was consistent with the Western blot results.ConclusionThe persistent plasticity changes of hypothalamus subunits NR1 and NR2B may be on of important mechanisms for early excitability alteration of HPA axis after severe burn.

Objective To investigate any potential and independent demographic and serologic risk factors contributing to bone destruction in patients with rheumatoid arthritis ( RA) . Methods A total of 445 patients with RA were recruited in this study. Three autoantibodies including rheumatoid factor ( RF) , anti-cyclic citrullinated peptide antibody ( anti-CCP antibody) and anti-citrullinated alpha-enolase peptide 1 antibody ( anti-CEP-1 antibody) were quantified by using specific ELISA kits. The hand radiographs of all subjects were graded by using the modified Sharp/van der Heijde score ( Sharp score) . The potential and in-dependent risk factors were assessed by using univariate linear regression analyses and the stepwise multiple regression analysis, respectively. Results Based upon the univariate regression analyses, 7 covariates were identified as the potential risk factors for bone destruction in patients with RA, which were female (β=0. 100, P=0. 035), longer disease duration (β=0. 498, P=3. 26×10-29), RF (β=0. 096, P=0. 042), younger age at onset (β=-0. 312, P=1. 60 × 10-11 ), anti-CCP antibody positive (β=0. 202, P=1.74×10-5), anti-CEP-1 antibody positive (β=0.148, P=0.017) and positive for either anti-CCP or anti-CEP-1 antibodies (β=0. 157, P=1. 42×10-3). However, smoking (β=-0. 121, P=0. 018) were identi-fied as the potential protective factors. The multiple regression analysis indicated that the longer disease du-ration (P=2. 24×10-15) and anti-CCP antibody positive (P=0. 012) were independent risk factors for bone destruction. Conclusion Female, longer disease duration, younger age at onset, RF, anti-CCP and anti-CEP-1antibodies are potential risk factors for bone damage in patients with RA. Moreover, longer disease du-ration and anti-CCP antibody are two independent risk factors contributing to bone destruction in RA.
