Bone marrow infiltration in lymphoma is crucial to the disease diagnosis,staging,treatment options and prognostic evaluation.Although bone marrow biopsy is the main detecting method,it has high false negative rate.At present,18F-fluorodeoxyglucose positron emission tomography-computed tomography (18 F-FDG PET-CT) technology which is integrating morphological characteristics with metabolic function provides a new way for the diagnosis,staging and prognostic evaluation of bone marrow infiltration in lymphoma due to its advantages of high sensitivity,high specificity and functional image.

Objective:To investigate the effect of the intact parathyroid hormone (iPTH) on residual renal function (RRF). Methods: The relationship between iPTH and calcium, phosphorum, product Ca?P, hypertension, triglycende, cholesterol,left ventricular mass index(LVMI) and RRF in 120 hemodialysis patients with chronic renal failure. Results: The results showed that 95. 9% of the hemodialysis patients with chronic renal failure had secondary parathyroldism. It was found that iPTH was positively correlated with SBP,DBP, product Ca?P, triglycende and LVMI, and negatively correlated with endogenous creatinine clearance rate and KT/V. RRF had positive correlation with KT/V and SBP,DBP, calcium, product Ca?P, triglyceride, cholesterol and LVMI. Conclusion: iPTH level is elevated in hemodialysis patients, which may lead to RRF loss.

Objective To investigate the expression level of lipocalin-type prostaglandin D synthase (L-PGDS) mRNA and its protein in glioma.Methods The L-PGDS mRNA was determined by real-time quantitative RT-PCR in 23 glioma and 5 healthy brain specimens. L-PGDS protein was detected by Western blot in cerebrospinal fluid (CSF) and brain tissue specimens.Results In 23 glioma specimens L-PGDS mRNA expression ranges from 1.5?10 3～7.0?10 4 copy/?g RNA, mean value is 1.6?10 4 copy/?g RNA. In 5 normal brain specimens, the mean value is 8.1?10 5 copy/?g RNA, statistic analysis indicates a distinct discrepancy ( P

Objective To investigate the effects of cystectasia with sodium hyaluronate solution on ketamine related cystitis.Methods From June 2008 to October 2012,29 patients with ketamine related cystitis were analyzed,among which 27 were males and 2 were females.Their age ranged from 18 to 36 years old with a mean age of 25.All of them had frequency,urgency,urodynia and suprapubic pain.Voiding volume ranged from 10 to 160 ml and the interval duration ranged from 10 to 60 min.The test of ketamine in urine was positive.Patients were divided into four groups according to the treatment modality,namely the surgical treatment group (group A,n =11),surgery followed by addiction relapse group (group B,n =7),drug treatment group (group C,n =6) and non-drug treatment group (group D,n =5).Patients in group A and B underwent cystectasia with sodium hyaluronate solution under combined spinal-epidural anesthesia,and patients in group B were reported of addiction relapse within 2 weeks after cystectasia treatment.Patients in group C were free of the addiction to ketamine,while those in group D still rely on the ketamine.The average urine volume,OABSS and PUF scores were recorded 2 weeks and 4 weeks after the treatment.Results Two weeks after cystectasia,the average urine volums in group A and B were (107.7±39.6) ml and (95.0±35.5) ml respectively,which was larger than that in group D (42.0±13.5) ml,plus the volume in group A was larger than that in group C (63.3± 16.3) ml.The aforementioned differences were considered statistically significant (P＜0.05).As for OABSS and PUF scores,scores in group A [(6.0±2.6),(14.8± 4.2)] were lower than those in group C [(9.5±2.4),(22.5±2.2)].Furthermore,scores in group B [(9.0±2.4),(19.57±2.7)] were lower than those in group D [(12.2±1.9),(26.4±3.5)] (P＜0.05).Four weeks later,the average urine volume,OABSS and PUF scores in group A [(106.4±37.5) ml,(5.6± 2.5),(13.5±4.0)] and group C[(113.3±27.3) ml,(6.3±2.2),(14.5±2.7)] were significantly different from those in group B [(52.1±21.6) ml,(11.1±1.3),(26.4±2.8)] and group D [(40.0±13.7)ml,(12.0±1.6),(26.6±3.6)] (P＜0.05).While,no obvious distinction was observed between group A and group C,group B and group D in terms of average urine volume,OABSS and PUF scores at 4 weeks postoperatively (P＞0.05).Conclusions Cystectasia can efficiently alleviate lower urinary tract syndromes in patients with ketamine related cystitis.

OBJECTIVETo observe the effect of Polygonatum sibiricum on Yin deficiency model rats induced by long-term overload swimming.

METHODExcept for the normal group, all of the remaining rats performed the long-term overload swimming for eight weeks, with five days every week and once every day, to establish the Yin deficiency model. The daily swimming time increased from 10 min to 180 min at the end of the 7th week, with the water depth of 60 cm and the water temperature at 30 degrees C. After the success of the modeling, the rats were orally administered with different doses of aqueous extracts from P. sibiricum (2.5, 10 g x kg(-1)) for eight weeks. After the final administration, their blood were collected from orbits to measure immunoglobulin A, G and M (IgA, IgG, IgM), interleukin 2 and 6 (IL-2, IL-6) and cAMP, cGMP contents in plasma General behavioral indicators (weight, facial temperature, pain threshold and holding power) of rats were observed during the drug administration.

RESULTCompared with the model control group, aqueous extracts from P. sibiricum was given for eight weeks to significantly increase the rat weight and holding power of Yin deficiency model rats, decrease the facial temperature and the sensitivity of pain threshold, and increase IgA, IgG, IgM and IL-6 content and IgG content in serum, but without statistical difference. Aqueous extracts from P. sibiricum (10 g x kg(-1)) could also increase IL-2 content in serum, and decrease cAMP content and cAMP/cGMP ratio.

CONCLUSIONP. sibiricum could improve the general behavioral indicators (weight, holding power, pain threshold and facial temperature), immunologic functions (IgA, IgG, IgM) and cyclic nucleotide (cAMP, cAMP/cGMP), so as to ameliorate such Yin deficiency symptoms as dysphoria in chestpalms-soles, weight loss, soreness and weakness of waist and knees, immunologic dysfunction and cyclic nucleotide system disorders.

[Abstract ] Objective C reactive protein (CRP), an in-flammatory maker, increased significantly among diabetes mellitus and other metabolic diseases.Meanwhile, adiponectin plays a vital role in anti-atherogenic, anti-inflammatory and anti-diabetic poten-tials.Further, it decreased in diabetes mellitus.To investigate the effects of C-reactive protein in the expression of high-molecular-weight adiponectin ( HMWA) and adiponectin multimerization. Methods The fully differentiated 3T3-L1 cells were respectively treated with 50μg/mL CRP for 0 h、6 h、12 h and 24 h , and different doses of CRP with 0μg/mL、5μg/mL、25μg/mL、50μg/mL for 24 h.The expres-sion of HMWA was further detected by Western blot.Additionally,
the mRNA expressions of adiponectin assembly related genes ( Ero1-L、DsbA-L、ERp44 ) were detected by Real time PCR after 50μg/mL CRP treatment for 24 h. Results After 24 h treatment, 25μg/mL CRP and 50μg/mL CRP resulted in a substantial reduction ( [70 ±7]%vs [44 ±7]%, P<0.05) while 5μg/mL CRP revealed no change.With the dose of 50μg/mL CRP treated, the ex-pression of HWMA were both inhibited after the 12 h and 24 h CRP treatment ([71 ±6]%vs [48 ±11]%, P<0.05), but for the 6 h CRP treatment group, HWMA remained unchanged.Additionally, CRP inhibited Ero1-L(86 ±10)%and DsbA-L(72 ±6)%gene expression and upregulated the expression of ERp44(141 ±23)%. Conclusion CRP decreases HMWA expression in a dose and time-dependent manner and inhibits the multimerization of adiponectin, thus weaken the benefits of adiponectin in diabetes.

Objective:To study the clinical features and prognostic factors of brain injury after radiothera-py for nasopharyngeal carcinoma(NPC).Methods:From January 1998 to June 2006,49 NPC patients with Dost-radiation brain injury in our hospital were analyzed retrospectively.Results:The incidence of post-radia-tion brain injury after single-pass radiotherapy and re-course radiotherapy was 2.31%and 9.64%.respectively ,(P＜0.05).The median latency period was 50.5 months for single-pass radiotherapy and 25.5 months for re-course radiotherapy.Fourty-nine patients suffered from radiation injury in the brain.The lesions were locat-ed in the temporal lobe in 37 patients(75.5%),in the pens in 9 patients(18.4%)and in mixed position in 3 pa-tients(6.1%).The symptoms and signs of the patients could be alleviated by therapy, but the quality of life was not improved.Conclusion:Radiation brain injury in NPC patients after radiotherapy is related to field de-sign.The incidence of radiation brain injury in the temporal lobe is the highest.Compared with single-pass ra-diotherapy, re-course radiotherapy leads to higher incidence of brain injury and shorter latency period.

Objective To investigate the clinical characteristics of systemic lupus erythematosus (SLE) and the situation of diagnosis after onset. Methods Three hundred outpatients diagnosed with SLE were investigated in the People's Hospital, the Third Hospital of Peking University, Xinjiang People's Hospital and the Affiliated Hospital from May to July 2008, including gender, age of onset, clinical manifestations and the site of first hospitalization. Results ① In the cross-sectional study, 300 SLE patients were investigated. The male-to-female ratio was 1:13. ② The most common manifestations at onset were arthritis (46.3%), rash (34.%) and fever (32.7%). Lupus nephritis was found to occur in a significantly higher frequency in male patients than female as the initial manifestation. 60.9% patients had lupus nephritis in the first year after onset. ③ 99.1% of the patients were correctly diagnosed after visiting rheumatologists. 23.7% of the SLE patients were not correctly diagnosed for more than one year after disease onset. Conclusion Arthritis, rash and fever are the most common initial clinical manifestations of SLE. Lupus nephritis is more commonly seen in male SLE patients than female at the disease onset. The diagnosis of lupus is delayed in certain proportion of patients.

To explore the status of HER-2 gene amplification and protein expression in Chinese esophageal squamous cell carcinoma patients and its relationship with the clinicopathological parameters.Methods The HER-2 gene amplification was detected by FISH and protein expression by IHC in 96 patients with esophageal squamous cell carcinoma that would be followed up for 3 years.Results Three cases presented with 3 +,15 cases with 2 +,11 cases with 1 +,and 67 with negative by HER-2 immunohistochemical staining;2 of 3 cases presented with HER-2 amplification in in 3 +,1 case presented with over 6 HER-2 copy numbers.HER-2 amplification and HER-2 overexpression had significant correlation (P ＜ 0.000 1).HER2 amplification or overexpression was associated with clinicopathological parameters,such as,carcinomas without necrosis (P =0.012) and lower stage (P =0.040).There was better DFS or OS trend in patients with HER-2 overexpression or amplification,but the significant difference did not reached.Conclusion This research has demonstrated the correspondence between gene amplification and protein overexpression of HER-2 in ESCC.HER-2 gene overexpression or amplification is a potential better predictive parameter in ESCC,but needs further study.
