OBJECTIVETo investigate the diagnostic value of FICTION (Fluorescence Immunophenotyping and Interphase Cytogenetics as a Tool for the Investigation of Neoplasms) technique, combining immunofluorescence and fluorescence in situ hybridization (FISH), to detect genetic aberrations in multiple myeloma (MM).

METHODSBone marrow samples were collected from 18 MM and 2 plasma cell leukemia (PCL) patients. Probes targeting IgH and MMSET were prepared using a Nick Translation Kit from Bacterial artificial chromosome (BAC) clones. The immunophenotyping was achieved via the CD138 tyramide signal amplification (TSA)-mediated immunofluorescence, followed by FISH with the prepared probes \[t(4;14), t(11;14), t(14;16)\] and the commercial deletion probes (13q and p53) to detect common genetic aberrations in MM.

RESULTSAll the 20 samples were assayed with the probes mentioned above, and revealed 4 cases with t(4;14), 6 with t(11;14), 1 with t(14;16), 3 with p53 deletion; and 8 with 13q deletion. The remaining 4 cases had none of the 5 aberrations.

CONCLUSIONFICTION technique facilitates the detection of genetic abnormalities of MM in situ; enhances both efficiency and sensitivity of positive detection, thus, could be used as the screening test of molecular diagnosis of MM to guide coming-up risk-adapted therapy and evaluate prognosis.

OBJECTIVETo analyze and evaluate the acceptability of mifepristone compatible with misoprostone versus conventional surgical abortion among women under unwanted early pregnancy, so as to help the unexpected pregnant women to choose the satisfactory abortion, and to provide the evidence for clinicians to make a proper clinical decision.

METHODSSix medical databases were searched, including MEDLINE, EMBASE, Cochrane library, CBMdisc, CNKI and VIP, together with twelve journals hand-searched, and references of included studies additionally searched. Two qualified reviewers reviewed the original articles, evaluating qualities of articles, and extracting data independently. After heterogeneity test, the data was pooled using Revman software if capable, or descriptive analysis was applied.

RESULTSIn total, nine original clinical controlled trials were included, containing 3565 cases. Before abortion, more unwanted pregnant women chose the medical abortion because they believed medical abortion was less painful than surgical abortion (OR = 466.51, 95% CI: 91.37 - 2381.88), but medical abortion was less time-consuming than surgical abortion (OR = 0.02, 95% CI: 0.01 - 0.06). After abortion, satisfaction with medical abortion was similar to that with surgical abortion, with insignificant difference (P = 0.89). However, second choice and recommendation rates of medical abortion were much higher than those of surgical abortion with OR and 95% CI as 2.72, 2.13 - 3.47 and 4.19, 2.16 - 11.16, respectively.

CONCLUSIONSMedical abortion was less painful than surgical abortion and the rate of second choice and recommendation to others were all also higher than those of surgical abortion. However, the process of medical abortion was not as quick as surgical abortion but the satifacation of both methods seemed similar. Therefore, the two artificial abortion methods were not recommended to replace each other at the present time.

A case-report on adenoma of the posterior urethra. Methods: In 131 cases of adenoma of the posterior urethra, aged 17- 79 (mean: 36.4) years, a detailed medical history was taken and urinalysis, urethroscopy, and prostatic specific antigen (PSA) immunohistochemical staining were performed. They were then treated with transurethral resection (TUR) or transurethral electric coagulation (TUEC). Results: Hemospermia occurred in 51% of the cases, hematuria in 38 %, bood overflow from the urethral orifice in 6 %, and dysuria in 5 %. The position of the tumor was at or around the verurumontanum. The appearance of the rumor was similar to those of a papilla, a villus, a dactyl or polyp, or simply an engorgement. The tumor contained glandular alveoli and adeno-epithelial cells. PSA immunohistochemistry was positive in the cytoplasm and nucleus of the adeno-epithelial cell. One hundred and tweenty-nine cases were cured after TUR or TUEC, while 2 patients recurred and were operated again. Conclusion: Adenoma of the posterior urethra is a common cause of hemospermia and hematuria in young men. Urethroscopic examination and biopsy are the principal diagnostic measures. TUR or TUEC are believed to be the treatment of choice with a short-term recurrence rate of around 1.5%.

BACKGROUNDNasopharygeal fibroangioma (NPF) can be approached through lateral rhinotomy, the middle skull fossa approach and the transcranial-facial combined approach. It is complicated and thus results in more insults, and when adopted, the total resection rate of tumor is still low. The nasal endoscope is minimally invasive, the dead angles of a craniotomy, such as sphenoid sinus, maxillary sinus, and nasopharynx are easily approached by an endoscope. Lateral rhinotomy have to make facial incision and affects maxillary bone development. We combined the craniotomy and endoscopic approach intending to take advantages of the two approaches.

METHODSTwelve NPF patients who underwent craniotomy with endoscopic assistance from March 2002 to July 2008 at the Beijing Tongren Hospital were selected. All patients were male. Their ages ranged from 11 to 33 years. The main symptoms were visual deterioration, exophthalmos, nasal obstruction, epistaxis and pharynx nasalis neoplasm. The diagnosis was based on CT, MRI and digital subtraction angiography (DSA). All patients had intracranial encroachment and all underwent DSA and embolism treatment were taken before surgery. Seven patients had a pterional craniotomy, five had a frontal-temporal-orbital-zygomatic craniotomy. Most of the tumor was resected piecemeal, then removed through the sphenoidal sinus. Finally, using an endoscope in the nasal cavity, tumor in nasal cavity was resected and removed through the sphenoidal sinus, observing the dead angle of the craniotomy and confirming that sinus drainage was unobstructed.

RESULTSThe tumor was removed completely in 11 patients and partially resected in one patient because of hemorrhage. One patient had an infection after the operation and one patient had cerebrospinal rhinorrhea 3 years after surgery that was remediated by endoscopic repair.

CONCLUSIONCraniotomy with endoscopic assistance in the treatment of NPF was minimally invasive, safe and efficient, and avoided facial incision.

OBJECTIVETo investigate the effects of anluohuaqianwan on experimental hepatic fibrosis induced by dimethyl nitrosamine (DMN) in rats.

METHODS36 male SD rats were randomly dividied into three groups: model group, normal group, anluohuaqianwan group. The rats in the three groups were treated with DMN daily for 4 weeks. The liver function was detected using auto biochemistry analyzer, the serum HA, LN, IV-C, PIIIP were detected by immunoradiometry, the histopathology was observed in the left liver lobe after HE staining, the expression of matrix metalloproteinase-2 (MMP-2) in liver tissue were detected by immunohistochemistry.

RESULTSThe serum levels of ALT, AST, ALP, TP, ALB and the contents of HA, LN, IV-C in model group were significantly increased compared to these in the normal group (P less than 0.01). The serum levels of ALT, AST and the contents of HA in anluohuaqianwan group were significantly lower than those in the model group (P less than 0.01). The liver MMP-2 in the model group was significantly increased compared to that in the normal group (P less than 0.05). The expression of MMP-2 in liver tissue of model group was lower than that in the anluohuaqianwan group (P less than 0.05).

CONCLUSIONAnluohuaqianwan can inhibit liver fibrosis in rats induced by DMN.

OBJECTIVETo investigate the association of 86 bp variable number tandem repeat (VNTR) polymorphism of interleukin-1 receptor antagonist (IL-1Ra) gene with lumbar disc disease and intervertebral disc degeneration.

METHODSThe 86 bp VNTR polymorphism of IL-1Ra gene was analyzed with PCR and electrophoresis for 81 patients with lumbar disc disease and 101 volunteers without sciatica (control). The grade of intervertebral disc degeneration was determined with magnetic resonance imaging, and the association of 86 bp VNTR polymorphisms with lumbar disc disease and intervertebral disc degeneration in those younger than 45 years was assessed.

RESULTSThe presence of 86bp VNTR polymorphisms of IL-1Ra gene was detected in both patients with lumbar disc disease and the control subjects. The distribution of 86 bp VNTR polymorphisms of IL-1Ra gene showed no significant difference between the two groups, but the distributions of 1/1, 1/2 and 2/2 or 1, 2 genotypes differed significantly. The current data did not support a significant association between the distribution of IL-1Ra gene 86bp VNTR polymorphism and lumbar disc degeneration.

CONCLUSIONSIL-1Ra gene 86bp VNTR polymorphism is present among Chinese population in association with lumbar disc disease, but not with lumbar disc degeneration.

OBJECTIVETo translate the English version of The Premature Ejaculation Diagnostic Tool (PEDT) into Chinese, evaluate its reliability and validity, and analyze its feasibility in the diagnosis of premature ejaculation (PE).

METHODSFollowing the forward-backward translation procedure, we developed the Chinese version of PEDT, which was then revised by andrologists and bilingual linguists. We enrolled subjects with or without PE from 15 urological or andrological clinics in China and obtained the information about their demographic characteristics, PEDT scores, and intra-vaginal ejaculation latency time (IELT). We evaluated the internal consistency of PEDT using Cronbach alpha, was examined its reliability and stability by test-retest analysis, analyzed its correlation with IELT by Spearman correlation analysis, and tested its sensitivity and specificity by receiver operating characteristic ( ROC) analysis.

RESULTSTotally, 570 PE patients (aged [30.66 ± 7.11] years) and 226 non-PE men (aged [33.01 ± 5.41] years) were recruited, with the mean IELT of (1.34 ± 0.54) min in the former and (11.09 ± 7.5) min in the latter group. The Cronbach's alpha of the Chinese version of PEDT was 0.79, and the test-retest correlation coefficient was 0.75 (P < 0.01). The PEDT score was negatively correlated with IELT (Spearman's p = -0.52, P < 0.01). When the cutoff value of PE diagnosis was defined as 7.5, the sensitivity and specificity of PEDT were 0.80 and 0.78, and when as 8.5, they were 0.72 and 0.89, respectively.

CONCLUSIONThe Chinese version of PEDT was demonstrated to have good internal consistency, reliability, and validity, as well as a high predictability for PE. It can be used as a reliable and convenient tool to screen PE among Chinese men.

Objective: To investigate the familial heritability of endometriosis and to compare the clinical characteristics of patients with or without a family history of endometriosis. Methods: From January 2020 to June 2022, 850 patients with endometriosis confirmed by laparotomy or laparoscopy in Peking University Third Hospital were included in this study. Clinical data were collected, family history was followed up, and the differences of clinical indicators between patients with and without family history of endometriosis were compared. Results: A total of 850 patients were enrolled, with an average age of (33.8±7.0) years old, 315 (37.1%, 315/850) patients in stage Ⅲ and 496 (58.4%, 496/850) patients in stage Ⅳ. There were 100 patients with family history of endometriosis, accounting for 11.8% (100/850). Most of the 113 relatives involved were mothers, daughters and sisters (76.1%, 86/113), 81.5% (22/27) of the second and third degree relatives were maternal relatives. The median ages of patients with and without family history of endometriosis were 30 and 33 years old respectively at the time of diagnosis. The unmarried rate of patients with family history was higher [42.0% (42/100) vs 26.3% (197/750)]. The percentage of dysmenorrhea patients with family history was higher [89.0% (89/100) vs 55.5% (416/750)]. The medians of dysmenorrhea score in patients with and without family history were 6 and 2, and the median durations of dysmenorrhea were 10 and 1 years. There were significant differences in age, marital status, percentage of dysmenorrhea, dysmenorrhea score and duration (all P<0.001). The median levels of serum cancer antigen (CA) 125 in patients with family history and patients without family history at the time of diagnosis were 57.5 and 46.9 kU/L respectively, with a statistically significant difference (P<0.05). However, there were no significant differences between the two groups in nationality, bady mass index, menarche age, menstrual cycle, menstrual period, menstrual volume, serum CA_19-9 level, cyst location and size, stage, history of adverse pregnancy and childbirth, infertility, adenomyosis and deep infiltrating endometriosis (all P>0.05). By comparing the specific conditions of dysmenorrhea patients with and without family history of endometriosis, there were no significant differences between the two groups in terms of the age of onset of dysmenorrhea, duration of dysmenorrhea, primary and secondary dysmenorrhea, and progressive aggravation of dysmenorrhea (all P>0.05). The difference in the degree of dysmenorrhea in dysmenorrhea patients with family history of endometriosis was significant (P<0.001). Conclusions: The incidence of endometriosis has a familial tendency, and most of the involved relatives are the first degree relatives. Compared with patients without family history of endometriosis, endometriosis patients with family history are diagnosed at an earlier age, with higher percentage of dysmenorrhea, had more severe dysmenorrhea and higher serum CA₁₂₅ level.

Brucea javanica oil emulsion (BJOE) has been used to treat tumor in China for more than 40 years. However, its components and effectiveness in the treatment of acute lymphocytic leukemia (ALL) and its mechanism of anti-cancer activity remain unknown. In the current study, high-performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD) was used to analyze the components of BJOE. Then, the anti-leukemia effects of BJOE were examined both in vitro and in vivo using ALL Jurkat cells and the p388 mouse leukemia transplant model, respectively. The primary ALL leukemia cells were also used to confirm the anti-leukemia effects of BJOE. The apoptotic-related results indicated that BJOE induced apoptosis in Jurkat cells and were suggestive of intrinsic apoptotic induction. Moreover, BJOE inhibited Akt (protein kinase B) activation and upregulated its downstream targets p53 and FoxO1 (forkhead box gene, group O-1) to initiate apoptosis. The activation of GSK3β was also involved. Our findings demonstrate that BJOE has anti-leukemia effects on ALL cells and can induce apoptosis in Jurkat cells through the phosphoinositide3-kinase (PI3K) /Akt signaling pathway.
