Objective To discuss pathological features of three cases of uterine primary NHL(non Hodgkin′s lymphoma).Methods The clinical and pathological data of 3 cases of NHL were collected.Immunohistochemical method was used to label the tumor cells.Their histological types were classified by the latest WHO Classification of Tumors of Haematopoietic and Lymphoid Tissues,and then differential diagnosis with other uterus diseases was offered.Results Three cases were presented with abnormal vaginal bleeding or ejecting as the first symptom,which was easily misdiagnosed as common diseases of the uterus in preliminary clinical and pathological diagnosis.Histopathology of general uterus specimens demonstrated that case one expressed CD3,CD56,TiA-1 and so on,and detected EBV virus cells expression,which supported the diagnosis of NK/T cell lymphoma.Another two cases expressed B cell-specific markers(CD20) and so on,and these tumor cells volume was 3 times larger than that of lymphocyte.These tumor cells had high proliferation index and supported diffuse large B-cell lymphoma diagnosis.Conclusion The tumor cells are like lymphocytes.We infiltrate endometria and myometrium,which is difficult to identify from endometria stromal sarcoma and other tumors,and need to use immunohistochemistry(IHC) for definitive diagnosis and differential diagnosis.

Objective:To compare the clinical efficacy of cold knife conization and transcervical resection of cervical lesion in the treatment of cervical intraepithelial neoplasia(CIN) Ⅱ,Ⅲ.Methods:The clinical data of 62 patients with CIN Ⅱ,Ⅲ underwent cold knife conization(CKC group) and 114 underwent transcervical resection of cervical lesion(TCRC group)in Zhujiang Hospital Southern Medical University from Jan 1 st 2010 to Jun 1 st 2014 were collected.The patients' age,pregnant frequency,mean operative time,preoperative pathological grading,blood loss during the operation and after the operation,positive resected margin,cervical stenosis and recurrence were compared between the two groups.Results:There was no difference on the patients age,pregnant frequency and preoperative pathological grading between the two groups(P ＞ 0.05).The mean blood loss during the operation (14.16 ± 14.10 ml)and the mean hospital stays(5.73 ± 1.43 days)of CKC group were significantly different from those of TCRC group(29.80 ±20.55 ml,4.75 ±1.23 days) (P＜0.05).There was no statistical difference on the mean operation time,postoperative vaginal bleeding rate,rate of positive resected margin,cervical stenosis rate and recurrence rate between CKC group and TCRC group (33.15 ± 11.42 min vs 33.18 ±14.61 min,33.9％ vs 21.1％,3.2％ vs 5.3％,4.8％ vs 4.4％,4.8％ vs 3.5％,respectively) (P＞0.05).The concordance rate of pre-operation and post operation pathological results of CKC group and TCRC group was 74.2％ (46/62) and 72.8％ (83/114) respectively,both kappa values were ＜ 0.75.Conclusions;Both CKC and TCRCT are safe as well as effective in the treatment of high-grade cervical intraepithelial neoplasia.Compared with CKC,TCRC has the advantage of short hospital stay,while much intraoperative blood loss,which calls for intraoperative attention.

Objective To investigate the clinical efficacy of mesalazine combined with bifico in the treatment of ulcerative co -litis (UC) and its effect on toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88).Methods A total of 86 cases of UC was randomly divided into the observation and control groups with 43 cases in each group .The observation group was given me-salazine combined bifico treatment , and the control group was given mesalazine , and eight weeks as a course of treatment .The clinical efficacy was observed .Serum TLR4 and MyD88 were tested.Adverse reaction in treatment was recorded .Results The total effective rate (95.35%) in observation group was significantly higher than that (81.40%) in control group( P <0.05).The serum TLR4 and MyD88 after treatment of two groups were significantly lower than that before treatment , respectively ( P <0.05 or P <0.01 ) , and the decline in TLR4 of observation group was superior to that of control group ( P <0.05 ) .The difference of adverse reaction rate in two groups was not significant ( P >0.05 ) .Conclusions Mesalazine combined with bifico in the treatment of UC is safe and effective . The effect may be related to regulation of peripheral blood TLR 4 and MyD88 content .

AIM:To investigate the histone modification changes of topoisomerase Ⅱα( TOPOⅡα) promoter regulatory factor Sp1 in the patients with chronic benzene poisoning .METHODS:The bone marrow samples were collect-ed from 25 chronic benzene poisoning cases and 25 controls.The chromatin immunoprecipitation assay was carried out to study the possible mechanism of TOPOⅡαpromoter regulatory factor Sp 1 expression changes .The mRNA expression of Sp1 was detected by RT-PCR.RESULTS:Compared with the controls , the histone H4 acetylation and histone H3 acetyla-tion of Sp1 in the chronic benzene poisoning patients significantly decreased (P<0.01), and histone H3K9 methylation level of Sp1 increased (P<0.01), but the histone H3K4 methylation level of SP1 was not obviously changed (P>0.05). The mRNA expression of Sp1 in the chronic benzene poisoning patients was significantly lower than that in the controls (P<0.05).CONCLUSION:In chronic benzene poisoning patients , the histone acetylation and methylation modification changes of TOPOⅡαpromoter regulatory factor Sp 1 accompanied with the changes of mRNA level are observed .Histone H4 and H3 acetylation and H3K9 methylation modification of Sp1 may play an important role in the benzene ’s hematopoiet-ic toxicities.

Objective In order to understand whether recombinant human growth hormone(r-hGH) can improve the idiopathic short stature(ISS) boys' final adult height(FAH).Methods We measured 16 cases diagnosed as ISS boys FAH, divided into 2 groups, of which 9 cases were not given r-hGH treatment, treatment group ,7 patients received r-hGH treatment, a dose of 0.1 ～ 0.13 U· kg-1·d-1, before going to sleep subcutaneous injection, duration of treatment was 6 ～ 20 months ( 11.9 ± 5.2 months).Results The treatment group compared with the average FAH FAH observation group had significantly improved the average(t =2.219,P<0.05).Conclusion r-hGH can improve the ISS boys FAH, but early treatment, the longer the course the more obvious effects.

The structure, karyotype and behavior of synaptonemal complex (SC) in the spermatocytes of hedgehog (Erinaceus euroaaus dealbatus (insectivora)) were analyzed by light and electron microscopy with a modified surface spread preparation which involves the use of sodium dodecyl-sulphate (SDS) and silver staining. The lateral elements of the synaptonemal complex have a constant width of about 50 nm, the distance between the two lateral elements is about 100 nm. The relative length and arm rationale constant for each autosomal SC. The relative length and arm ratio constant for ea of the autosomal SCs are very similar to that of mitotic autosome.The X and Y chromosome axes have a clear morphological distinction from the autosomal SC. The axes of X and Y chromosome pair and form a SC of certain length at pachytene stage. The axes of unpaired X and Y chromosome are heteropycnotic and display various morphological complexities. But these differentiations in hedgehog are primary than in other mammalians, such as human and mice. At pachytene stage the X and Y chromosome display an extensive side-by-side pairing segment with decreasing length as meiotic prophase progressed.

Objective To evaluate the application of “expert-guided network tracking system” in training community general practitioner for hypertension management.Methods Total 855 general practitioners (GPs) from 20 community health service centers in Hangzhou,Jiaxing and Shaoxing of Zhejiang province were divided into two groups: 430 GPs from 10 community health centers received training for hypertension management using “ expert-guided networking tracking system” (intervention group) in December 2008 and 425 GPs from another 10 health centers received conventional training (control group).Questionnaire surveys about the knowledge and skill of hypertension management were conducted before and 3 y after training.Results The awareness rates of knowledge about hypertension prevention and control,non-drug therapy and drug therapy increased from 37.0％ (159/430),45.6％ (196/430),42.8％ (184/430) to 66.8％ (284/425),81.4％ (346/425),77.6％ (330/425),respectively and the accuracy of case analysis increased from 38.4％ (490/1290) to 73.3％ (946/1290) (P ＜0.01) after training in intervention group.Meanwhile the knowledge and case management abilities in control group were also improved after conventional training,but the degree was significantly lower than that in the intervention group.Conclusions “Expert-guided networking tracking system” can significantly improve the knowledge and skills for hypertension management in community general practitioners.

Blood glucose levels of 220 days were recorded in 85 type 2 diabetic patients for monitoring glycemia for 48-72 h each one by the continuous glucose monitoring system (CGMS). Frequencies of nocturnal hypoglycemia (blood glucose≤2. 8mmol/L) were estimated when bedtime blood glucose levels were≤4.4mmol/ L,≤5.0mmol/L,≤5. 6mmol/L,≤6.1mmol/L,≤6. 7mmol/L, or≤7. 2mmol/L respectively. Nocturnal hypoglycemia occurred in 39 nights of 220 days (17.7%) of 26 patients and their bedtime blood glucose level was (4.4?2.6)mmol/L with a range from 2. 2 to 12. 6 mmol/L. Using a cut-off of bedtime blood glucose at≤6. 7 mmol/L, area under the ROC curve was reached maximal value (0. 359?0. 046). The positive predictive value was 25% and the negative predictive value was 91. 7%. CCMS is a useful tool to detect unaware nocturnal hypoglycemia.
