Objective To assess the clinical characteristics of benign prostatic hyperplasia (BPH) patients and patients's attitude towards BPH and BPH therapy. Methods The question-naires were distributed to 3560 BPH patients throughout the country during the period of Prostate Health Educational Programmer (PHELP). The survey was mainly focused on the questions of patient understanding toward BPH, the preference of treatment and international prostate score scale.Results The evaluations based on 2878 completed patient's questionnaires showed that 86. 0% of patients were diagnosed with moderate or severe low urinary tract syndrome. The main reasons for seek treatment was irritative symptoms (64. 1%), obstructive symptoms ( 41. 7%), physical checkup (41.0%), worry about prostate cancer(14. 5%). Most of patients sought treatment from big hospitals. Most of patients (69.1%) had right understanding towards BPH. Nocturia was the most bothersome of lower urinary tract symptoms(LUTS) suggestive of BPH. Rapid LUTS improvement was the patient's main objective (87.4%). Conclusions Chinese patients did not recognize the complications of BPH progression. Irritative symptoms are the main reasons for seek treatment. Nocturia is most bothersome syndrome, which deteriorates quality of life mostly.

OBJECTIVE: To observe the effect of manual acupuncture stimulation of paired "Baihui" (GV 20)+ "Shenmen" (HT 7), GV 20+ "Sanyinjiao" (SP 6), and GV 20+ non-acupoint on expression of melatonine (MT) and suprachiasmatic melatonin receptor 1 (MT1) and melatonin receptor 2 (MT2) mRNAs in insomnia rats, so as to explore their action difference and the underlying mechanism in improving insomnia. METHODS: Male SD rats were randomly divided into normal control (n=12), mo-del (n=8), GV 20+HT 7(n=12), GV 20+SP 6(n=11), and GV 20+ non-acupoint (n=10) groups. The insomnia model was established by intraperitoneal injection of Para-chlorophenylalanine suspension (50 mg/mL, 50 mg/100 g), once daily for 2 days. The abovementioned acupoints GV 20, bilateral HT 7, SP 6 and non-acupoints (the midpoint between the elbow-tip and armpit on the medial side of the upper-arm) were punctured with filiform needles and manipulated by rotating the needle for about 1 min which was repeated once again every 10 min during 30 minutes' needle-retaining. The treatment was conducted once daily for 7 days. The expression levels of MT immunoactivity in the conarium tissue, and MT1 and MT2 mRNAs of the suprachiasmatic nucleus (SCN) region were detected using immunohistochemistry and fluorescence quantitative real time-PCR, respectively. RESULTS: After modeling, the expression levels of pineal MT (an increase of gray value means a decrease of immunoactivity), SCN MT1 and MT2 mRNAs were notably down-regulated in the model group relevant to the normal control group (P<0.05, P<0.01). Following the treatment, the down-regulated expression levels of MT protein, and MT1 and MT2 mRNAs were obviously reversed in the GV 20 + HT 7, GV 20 + SP 6 groups relevant to the model group (P<0.05, P<0.01). The therapeutic effect of GV 20+ HT 7 was superior to that of GV 20+ non-acupoint in up-regulating the expression of MT1 mRNA (P<0.01), and markedly superior to that of GV 20+ SP 6 and GV 20+ non-acupoint in increasing the sleep duration and in up-regulating the expression of MT2 mRNA (P<0.01). No significant differences were found among the 3 treatment groups in up-regulating the expression of MT (P>0.05). CONCLUSION: Manual acupuncture stimulation of GV 20+ HT 7 and GV 20+ SP 6 can improve the sleep disorder in insomnia rats, which may be related to its effects in increasing the levels of pineal MT protein, and MT1 and MT2 mRNAs in hypothalamic SCN.

OBJECTIVE: To observe the effect of herbal cake-separated moxibustion on blood lipid-apoprotein levels and the expression of Toll-like receptor 2 (TLR 2), TLR 4 and nuclear factor kappa B(NF-κB) mRNAs in atherosclerotic (AS) vulnerable plaques of hyperglycemia rabbits, so as to explore its mechanism underlying improvement of atherosclerosis. METHODS: Sixty New Zealand rabbits were randomly divided into 5 groups: control, model, direct moxibustion, herbal-cake-separated moxibustion and medication groups(n＝12 rabbits in each group). The AS vulnerable plaque model was established by high-fat forage feeding plus balloon-induced abdominal aorta injury and gene transfection of Ad 5-p 53 recombinant vector. Direct moxibustion or herbal-cake-separated moxibustion was applied to "Juque" (CV 14) and bilateral "Tianshu" (ST 25), "Fenglong" (ST 40), or bilateral "Xinshu" (BL 15), "Pishu" (BL 20) and "Ganshu" (BL 18) for 15－20 min every time. The medication group was treated by feeding Atorvastatin. All the treatments were conducted once daily for 8 weeks. Plasma total cholesterol(TC) and triglyceri-de(TG) contents were detected by enzyme method, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) contents detected by colorimetric determination, and plasma apolipoprotein A(Apo-A) and apolipoprotein B(Apo-B) levels determined by electrophoretic method. The pathological changes of vulnerable plaque and the aortic intima and media thickness were observed under light microscope after H．E. staining. The expression levels of TLR 2, TLR 4 and NF-κB mRNAs in AS plaques were determined by quantitative real-time PCR. RESULTS: After modeling, the levels of plasma TC, TG, LDL and Apo-B in the model group were remarkably increased (P<0.01), and Apo-A and HDL/LDL were significantly decreased in comparison with the control group (P<0.01). Additionally, the aortic intima and media thickness and the expression levels of TLR 2, TLR 4 and NF-κB mRNAs in AS plaques were significantly increased (P<0.01). After the treatment, the elevated levels of plasma TC, TG, LDL and Apo-B, the aortic intima thickness and media thickness, and the expression levels of TLR 2, TLR 4 and NF-κB mRNAs in the 3 treatment groups were significantly down-regulated in comparison with the model group (P<0.05, P<0.01), while the decreased levels of Apo-A and HDL/LDL were considerably increased (P<0.01). Comparison among the 3 treatment groups showed that the therapeutic effects of the herbal-cake-separated moxibustion and medication were significantly superior to those of the direct moxibustion in down-regulating the levels of TC, TG, LDL, Apo-B, TLR 2 mRNA, TLR 4 mRNA and NF-κB mRNA, and reducing the thickness of the aortic intima and media, as well as in up-regulating the levels of Apo-A and HDL/LDL (P<0.05, P<0.01). No significant differences were found between the herbal-cake-separated moxibustion and medication groups in the above-mentioned indexes (P>0.05). CONCLUSION: Herbal-cake-separated moxibustion has a positive role in stabilizing AS vulnerable plaque in hyperglycemia rabbits, which may be associated with its effects in regulating blood lipid-apolipoprotein levels and inhibiting the expression of TLR 2, TLR 4 and NF-κB mRNAs in vulnerable plaques.

Objective To observe the effects of acupuncture treatment on the levels of HPA axis related hormones and acupoint compatibility in insomnia rats; To discuss the mechanism of action for acupuncture treatment. Methods Chlorophenylalanine suspension was under intraperitoneal injection to establish insomnia model rats. Sixty SD rats were randomly divided into blank group, model group, Baihui+Shenmen group, Baihui+Sanyinjiao group, Baihui+non-acupoint group, with 12 rats in each group. Each treatment group received acupuncture in relevant acupoints, 30 min each time, for 7 d. ELISA was used to measure the levels of CRH, ACTH and CORT. Results Compared with the model group, the levels of CRH, ACTH and CORT of the acupuncture groups decreased to some extent. In the three acupuncture groups, the efficacy of Baihui+Shenmen group was better than that of Baihui+Sanyinjiao group and Baihui+non-non-acupoint group. Conclusion Acupuncture treatment may calm and soothe the nerves to release the insomnia through regulating HPA axis related hormones. Acupuncture acupoints at different meridians may be one of the factors that cause the difference of acupoints compatibility effect.

Objective To observe the effects of acupuncture in acupoints at different meridians on 5-HT, DA, NE in the peripheral serum of insomnia rats; To explore the mechanism of action of acupuncture for the treatment of insomnia. Methods Sixty SD rats were randomly divided into blank group, model group, Baihui+Shenmen group, Baihui+Sanyinjiao group, and Baihui+non-acupoint group, with 12 rats in each group. Injection of PCPA suspension of rats was used to establish insomnia model. Each acupuncture group received corresponding acupoints, 30 min each time, for 7 days. The levels of 5-HT, DA and NE in serum were measured by ELISA. Results Compared with the blank group, the levels of 5-HT, DA and NE in the model group were significantly higher than those in the blank group (P<0.01). Compared with the model group, the contents of DA and NE in the acupuncture groups were significantly lower than those in the model group (P<0.05, P<0.01), and the 5-HT in Baihui+Sanyinjiao group was significantly lower than those in the model group (P<0.05). Among all acupuncture groups, overall efficacy of Baihui+Shenmen group was better than Baihui+Sanyinjiao group and Baihui+non-acupoint group. Conclusion Acupuncture can improve sleep structure in rats may be related to serum monoamine neurotransmitters. Acupuncture in acupoints at different meridians may be one of the influencing factors of acupoint compatibility effects.

Objective To study the vaginal microecology of the patients in the outpatient department of Obstetrics and gynecology in China.Methods A multicenter cross-sectional study was conducted in gynecologic clinic of 9 collaborative hospitals in China.200 consecutive patients were collected in each hospital and their vaginal microecology combined with related factors were analyzed.Results A total of 2 093 specimens were collected in this study.The detection rate of Trichomonas was 5.5%(115/2 093). The detection rate of Candida mycelia was 15.9%(333/2 093), with germinal spores was 4.1%(86/2093).The detection rate of bacterial vaginosis was 18.8%(394/2 093).The distribution results of vaginal flora in patients showed that the normal flora accounted for only 27.3%(571/2 093).The normal flora with the insufficiency of H2O2 accounted for 23%(480/2 093).The bacteria inhibiting flora accounted for 3.8%(79/2 093).The abnormal microflora(non BV type)accounted for 14.9%(312/2 093).The abnormal microflora(BV intermediate type)accounted for 13.4%(280/2 093).The abnormal microflora(BV type)accounted for 17.6%(369/2 093).The average pH of vaginal discharge was 4.58 ±0.495.There was no significant difference of the incidence of trichomonas and bacterial vaginosis between north and south of the Yangtze river, while the detection rate of fungal hyphae and the fungal spores is significantly higher in the south than that in the north.The analysis results of factors affecting the microecology showed that age and contraception methods were two important factors.The patients′age from bacteria inhibition group was 49.64 +16.68 which was significantly higher than that of the other microecology groups.The proportion of abnormal microflora of patients from the oral contraceptive group was 40%(20/50).The proportion of abnormal microflora of patients from IUD group was 36.6%(63/172).Compared with these two contraception methods, the proportion of abnormal microflora of patients from condoms usage group was 27.8%(91/327)which was significantly lower.The incidence of abnormal leucorrhea in the normal group was 37.7%, which was significantly lower than that of other abnormal groups.Conclusion This study showed the vaginal microecology status of the Chinese outpatient ′s clinic and found that the vagina microecology was related to age, region and contraceptive methods.The typical manifestation of microecological abnormality is the increase of leucorrhea.(Chin J Lab Med,2018, 41:287-291)

OBJECTIVETo analyze CD21 expression in diffuse large B cell lymphoma (DLBCL) and to explore its relationship with the clinicopathological characteristics and prognosis.

METHODSThe clinical data from 80 DLBCL patients who were treated in First Hospital of Jilin University from June 2005 to September 2011 were retrospectively analyzed. The cases were subjected to immunohistochemical staining (SP method) for Ki-67, CD20, CD79a, CD3, CD43, CD5, cyclin D1, bcl-2, CD10, bcl-6, GCET-1, FOXP-1 and MUM-1 protein expression in the tumor tissue. Immunohistochemistry was also used to detect CD21 expression in the tumor tissue. SPSS 18.0 was used to analyze the relationship between CD21 expression and various clinical factors, and the relationship between various clinical factors including CD21 and overall survival.

RESULTSIn the patients aged under 60 years, the incidence of CD21(+) lymphoma (64.0%, 16/25) was significantly higher than that of CD21(-) lymphoma (38.2%, 21/55). There were more CD21(+) lymphoma patients who were at clinical stages I-II (52.0%, 13/25) than patients with CD21(-)lymphomas (23.6%, 13/55). There were also more CD21(+) lymphoma patients (68.0%, 17/25) having less than two extranodal sites involvement than CD21(-)lymphoma patients (41.8%, 23/55). In addition, there were more CD21(+) lymphoma patients with IPI 0-2 (68.0%, 17/25) than CD21(-)lymphoma patients (41.8%, 23/55). There were more CD21(+) lymphoma patients with GCB subtype (60.0%, 15/25) than CD21(-)lymphoma patients (23.6%, 13/55). Death related to DLBCL was less in CD21(+) lymphoma patients (32.0%, 8/25) than CD21(-) lymphoma patients (56.4%, 31/55). Univariate analysis showed that these clinical pathological characteristics affected the overall survival of DLBCL patients, including age, ECOG score, LDH, extranodal involvement, IPI index, CD21 expression, treatment option and efficacy (P < 0.05) . Cox multivariate analysis showed that ECOG score, LDH, extranodal involvement, CD21 expression were closely related to prognosis, and the difference was statistically significant (P < 0.05). Among the 80 patients, the overall survival (OS) of CD21(+) lymphoma patients was significantly higher than that of CD21(-) lymphoma patients.

CONCLUSIONSThe expression of CD21 is associated with young age at onset, early clinical stage, small number of involvement and low IPI index. The OS and median overall survival of CD21(+) lymphoma patients are significantly higher than those of CD21(-) patients. CD21 expression, ECOG score, LDH, extranodal involvement are independent prognostic factors in DLBCL, and in particular, the expression of CD21 is more significant in the prognosis of DLBCL patients.

BACKGROUNDFor the renal transplant recipients, anemia is one of the common complications and becomes a major medical issue before transplantation. Haemoglobin (Hb) is used as a prognostic indicator, although the optimal pre-transplantation Hb concentration associated with positive prognosis is still controversial. The aim of this study was to detect the optimal Hb concentration on predicting the graft survival and function.

METHODSA retrospective cohort study was conducted by reviewing the medical records of the patients who received renal transplantations at our center from January 2004 to June 2008. Patients were divided into two groups: high Hb group (≥ 100 g/L, n = 79) and low Hb group (< 100 g/L, n = 63). There was no significant difference between the two groups regarding sex, age, blood type and tissue types. Renal function among the two groups was measured and compared. Panel reacting antigens (PRA) of all the recipients were negative. The effect of preoperative hemoglobin concentration on the postoperative renal function recovery in both groups was further analyzed.

RESULTSA total of 14 acute rejection episodes occurred, including 5 patients in the high Hb group (7.9%) and 9 in the low Hb group (11.4%, P > 0.05). The serum creatinine level at one-year post-transplantation of the low Hb group was significantly higher than that of the high Hb group ((117.8 ± 36.3) µmol/L vs. (103.1 ± 35.5) µmol/L, P < 0.05). For one-year actuarial patient and graft survival, incidence of delayed graft function (DGF), serum creatinine concentrations at 1, 3, 6 months post-transplantation, the incidence of cytomegalovirus (CMV) infection, post-transplantation anemia (PTA) and post-transplantation diabetes mellitus (PTDM) of both groups, there were no statistically significant differences.

CONCLUSIONPre-transplantation Hb concentration has significant effect on one-year creatinine concentration, but can not significantly affect acute rejection episodes, DGF, PTA, CMV infection and PTDM.
