Abstract
OBJECTIVES This study was to investigate the clinical efficacy of a gonadotrophin-releasing hormone agonist (GnRH-a) combined with high-intensity focused ultrasound (HIFU) ablation treatment for adenomyosis. DESIGN A non-randomized prospective study. SETTING Gynaecological Minimally Invasive Centre in a single hospital. POPULATION Patients with adenomyosis. METHODS Seventy-nine patients with adenomyosis were enrolled, including 55 patients in the control group treated with only HIFU and 24 patients in the study group treated with GnRH-a combined with HIFU. All the patients follow up 6 months after the HIFU procedure. The related parameters in the two groups were assessed before and 3 months as well as 6 months after treatment including serum levels of tumor marker and cytokine, volumes of uterine, adenomyotic lesion, and menstrual blood, as well as dysmenorrheal scores. MAIN OUTCOME MEASURES Differences between the group treated with HIFU alone and the group treated with GnRH-a combined with HIFU. RESULTS Before HIFU treatment, no significant difference was observed in serum levels of CA125, CA19-9, and interleukin-6 (IL-6), the volumes of uterine, adenomyotic lesion, and menstrual blood, as well as dysmenorrhea scores between the two groups. (P > 0.05). The serum CA125 levels significantly decreased in both groups after HIFU, but the serum CA125 levels in the study group were still significantly lower than those in the control group (P < 0.05). The volume of uterine and adenomyotic lesion significantly decreased in both groups after HIFU procedure, and decreased even more in the study group 3 and 6 months after treatment (P < 0.05). Dysmenorrhea scores and menstruation volumes significantly decreased in both groups after HIFU treatment. Moreover in the study group were significantly lower than those in the control group after 3 and 6 months (P < 0.05). No significant difference was observed in the rate of adverse effects between the two groups. CONCLUSIONS The short-term follow-up results indicate that the combination of GnRH-a and HIFU treatment significantly decreased serum CA125 levels, volumes of uterine, adenomyotic lesion and menstrual blood, as well as dysmenorrhea scores, and improved the clinical outcomes compared with the HIFU ablation alone in patients with adenomyosis. However, the further follow-up is needed to explore the long-term effects. TWEETABLE ABSTRACT A combination of GnRH-a with HIFU in the treatment of adenomyosis significantly decreased serum CA125 levels, uterine and adenomyotic lesion volumes, dysmenorrhea scores, and menstrual blood volumes.

Abstract
A minority of hand, foot and mouth disease (HFMD) caused by enterovirus A71 (EV-A71) results in severe neural complications. However, whether monocyte-mediated immunity is involved in the disease progression of HFMD remains unknown. One hundred and twenty mild and 103 severe HFMD patients were recruited and enzyme-linked immunosorbent assay (ELISA), flow cytometry and Transwell culture were performed in the study. Peripheral monocyte counts were lower in both absolute counts and frequencies in severe cases compared to mild cases. After screening 10 monocyte-related cytokines by ELISA, only monocyte chemoattractant protein-1 (MCP-1) was found at higher levels in sera of mild cases compared to those with severe symptoms. Monocytes purified from mild cases produced more MCP-1 than the cells from severe patients when stimulated in vitro. We observed that immune exhaustion markers programmed death 1 (PD-1) and programmed death ligand 1 (PD-L1) were highly regulated on the surface of monocytes from severe cases compared to mild cases. PD-L1 blockade induced a higher production of MCP-1 in the supernatant of a Transwell system. The production of MCP-1 also increased following PD-L1 blockade of purified monocytes activated by granulocyte-macrophage colony-stimulating factor (GM-CSF) combined with R848 or EV-A71 virus. Our results indicate that absolute count, frequency and levels of MCP-1 secretion of peripheral monocytes, together with their immune status, probably contribute to differential disease prognosis in EV-A71-associated HFMD.

Abstract
OBJECTIVES We carried out a randomized multicentre study in China to investigate whether the clofazimine would improve the efficacy of the standardized regimen in patients with multidrug-resistant tuberculosis (MDR-TB). METHODS Patients with MDR-TB managed in 17 TB specialist hospitals in China between September 2009 and September 2011 were randomly assigned to the treatment groups at enrolment. In the intervention group, 100 mg clofazimine per day was added to the standardized regimen. The primary outcome was the proportion of patients with successful outcomes. RESULTS From the 156 patients that were screened, 74 were assigned to the control group and 66 to the clofazimine group. Of the 66 cases analysed for clinical outcome in the clofazimine group, 36 patients were cured, and seven completed treatment, yielding a favourable outcome rate of 65.1%. The proportion of patients with favourable outcomes receiving the control regimen was 47.3% (35/74), which was significantly lower than that in the clofazimine group (p 0.034, relative risk 0.661, 95% CI 0.243-0.949). CONCLUSIONS The addition of clofazimine to the standard regimen improved the treatment of MDR-TB.

Abstract
Hepatitis A virus (HAV) is a major cause of acute viral hepatitis, which can lead to severe cases and acute liver failure. A 41-year-old Chinese military officer of the United Nations peacekeeping forces in South Sudan manifested fever, jaundice and coagulation dysfunction. The patient initially had a negative anti-HAV IgM antibody test result but a positive anti-HAV-IgM antibody test result five days after his alanine aminotransferase (ALT) levels peaked. He was given telemedicine consultation and was transferred to a Chinese military hospital specialising in infectious diseases for treatment of severe acute HAV infection. The peak ALT, aspartate aminotransferase, total bilirubin and international standard ratio were 5410 U/L, 3475 U/L, 225.1 µmol/L and 2.12 during hospitalisation, respectively. Military personnel undergoing missions in areas with high prevalence of HAV should be tested for previous HAV infection before departure if they have not been previously vaccinated. If negative results are obtained, they should be vaccinated. Anti-HAV-IgM examination should be repeated after the first negative test result is obtained to eliminate the effects of a window period if a clinical suspicion exists. If a life-threatening case of HAV infection is present, the patient should be transported to a base military hospital specialising in infectious diseases for treatment.

Abstract
OBJECTIVE We evaluated the impact of pre-therapeutic hematopoiesis on survival, hematotoxicity (HT) and number of 223Radium (223Ra) treatments in patients with metastatic castration-resistant prostate cancer. SUBJECTS AND METHOD Hemoglobin-levels (Hb), the number of platelets (Plts), leukocytes (Leuk), and survival data were collected in 56 patients treated with 223Ra. Pre-therapeutic hematopoiesis as well as adverse events during and after therapy were scored (grade 0-4) according to the CTCAE recommendations. The association of pre-therapeutic hematopoiesis, survival, HT and numbers of 223Ra cycles was analyzed. RESULTS Median survival in all patients was 69.9 weeks; 77% of patients had pre-existing impaired Hb (1.7% grade 3, 12.5% grade 2, 62.5% grade 1). 8/56 (14.3%) had impaired Plt (grade 1) Maximum toxicity (Tox) grades of patients during treatment were grade 4 (Hb 1.7%; Plt 1.7%), grade 3 (Hb 14.3%; Plt 7.1%; Leu 7.1%), grade 2 (Hb 33.9%; Plt 7.1%; Leu 23.2%), grade 1 (Hb 46.4%; Plt 17.9%; Leu 23.2%) and grade 0 (Hb 5.4%; Plt 66.1%; Leu 44.6%). Interestingly, patients with thrombocytopenia had a significantly shorter survival compared to those with normal Plt levels (21 weeks vs not reached; P<0.003). As expected patients with pre-therapeutic low Hb-level (<10g/dL) had a significantly shorter survival compared to those with Hb-level >10g/dL (28 weeks vs not reached, P<0.004), whereas survival of patients with mildly impaired Hb (>10 but <13.5g/dL) did not differ from patients with normal levels of Hb (X vs. Y, P=...). Also patients with impaired Hb also developed significantly more grade 3 and 4 HT (Hb <10g/dL: 42.9 vs 14.3%, P<0.001; Plt <150G/mL: 25.0% vs 6.3%; P=0.002) and received significantly fewer treatment cycles (Hb<10g/dL: 5.1 vs 5.8, P<0.04; Plt <150G/mL: 3.4 vs 5.6; P<0.001). Neither extent of bone metastases nor previous chemotherapy were associated with survival, number of 223Ra cycles and HT. CONCLUSION Patients with metastatic castration-resistant prostate cancer and impaired hematopoiesis, in particular thrombocytopenia and anemia, before 223Ra therapy suffer from significantly more high-grade HT, shorter survival and receive significantly fewer 223Ra treatments. Therefore, Hb-levels and platelet counts are essential parameters for adequate patient selection for 223Ra therapy.

Abstract
Objective: To investigate the related factors on effects of uterine artery embolization(UAE)in the treatment of dysmenorrhea in patients with adenomyosis, and to construct and validate the efficacy prediction model. Methods: A total of 127 cases of adenomyosis patients with symptoms of dysmenorrhea in Guangzhou No.1 People's Hospital and Nanfang Hospital of Southern Medical University from June 1999 to December 2009 were reviewed. The evaluation standard was to improve the degree of dysmenorrhea, the related factors of efficacy were analysed. Combined with artificial neural network theory, the effect prediction model was constructed, and the effectiveness of the model was evaluated using receiver operating characteristic(ROC)curve, and the effectiveness of the cut-off point was calculated. The model was validated by 68 cases of patients with adenomyosis in the Nanfang Hospital from January 2010 to November 2014. Results: (1)In 127 cases of dysmenorrhea patients, UAE treatment was effective in 98 cases, effective rate was 77.2%(98/127).(2)Age was an independent predictor of effective UAE treatment(HR= 1.129, P=0.026); in the range of this study, the greater the age, the higher the UAE treatment efficiency.(3)The developing situation of ovary branches of uterine artery was an independent predictor of effective UAE treatment(HR=0.460, P=0.020), the efficiency of patients whose intraoperative bilateral uterine artery ovarian branch did not develop was 89.7%(35/39), the efficiency of patients whose unilateral uterine artery ovarian branch was developing was 84.1%(37/44)and the efficiency of patients whose bilateral uterine artery ovarian branch were developing was 59.1%(26/44).(4)Blood supply of adenomyosisis was an independent predictor of effective UAE treatment(HR=0.313, P=0.001). Type Ⅰ(bilateral predominated)patients, efficiency was 93.5%(43/46); type Ⅱ(bilateral balanced)patients, efficiency was 78.0%(39/50); type Ⅲ(unilateral predominated)patients, efficiency was 51.6%(16/31).(5)UAE for the treatment of adenomyosis efficacy of artificial neural network prediction model was constructed, the model's area under the ROC curve was 0.808, the optimal cut-off point was 0.669 13. Actual verification of the model, sensitivity was 96.5%, specificity was 81.8%, positive predictive value was 96.5% and negative predictive value was 81.8%, the total accuracy was 94.1%. Conclusions: (1)Age, the developing situation of ovary branches and blood supply of adenomyosis are the independent predictors of effective UAE treatment.(2)The artificial neural network prediction model is satisfied with the accuracy and the accuracy of prediction.

Abstract
Objective: To estimate the expression of ER and PR in the endometrium of both intrauterine adhesions (IUA) and non-IUA specimens. Methods: The endometrium specimens from patients undergoing hysteroscopy for confirmed moderate IUA (n=20: 10 in proliferative phase, and 10 in secretory phase) were enrolled as the IUA group in Beijing Obstetrics and Gynecology Hospital from October 2014 to August 2015. The specimens scheduled for hysteroscopy due to infertility were recruited into the control group (n=26: 13 in proliferative phase, and 13 in secretory phase). Immunohistochemistry and quantificational real-time PCR (qRT-PCR) were used to detect the expression of ER-α, ER-β and PR in endometrium with different menstrual period in both groups. Results: (1) Location: in both groups, the expression of ER-α, ER-β and PR appeared in the endometrial glandular epithelial cells and the stromal cells of the endometrium. The positive brown granules of ER-α, ER-β and PR appeared mainly in cell nucleus. (2) ER-α and ER-β in the endometrium: the protein expression of ER-α and ER-β in IUA group (proliferative phase: 0.657±0.028, 0.493±0.023; secretory phase: 0.537±0.020, 0.365±0.031) were significantly higher than those of control group (proliferative phase: 0.586±0.025, 0.437±0.022; secretory phase: 0.459±0.025, 0.323±0.017; all P<0.01). And the ER-α and ER-β mRNA expressions in IUA group were 2.524±0.296, 1.947±0.339, higher than those of control group in the proliferative phase (all P<0.01), and in the secretory phase (1.977±0.333, 1.345±0.292) were also higher than those in the control group (all P<0.01). (3) PR in the endometrium: the protein expression of PR was not significantly different between IUA group (proliferative phase: 0.248±0.025, secretory phase: 0.194±0.024) and control group (proliferative phase: 0.234±0.019, secretory phase: 0.186±0.020; P=0.162, 0.359). Meanwhile, there were no statistical differences in the mRNA expression of PR in both groups with different menstrual period (proliferative phase: 1.144±0.384 versus 0.981±0.306, secretory phase: 0.763±0.237 versus 0.631±0.203; P=0.270, 0.166). (4) ER and PR expression in menstrual cycles: the expression of ER-α, ER-β and PR in the IUA group changed with the menstrual cycles, and their expression in the proliferative phase were higher than those in the secretory phase (all P<0.05). Conclusions: The expression of ER-α and ER-β in the endometrium of IUA patients changes with menstrual cycle, and are higher compared with those in normal endometrium. No difference is found in the PR expression between the two groups.

Abstract
The authors describe a rare case of a giant nabothian cyst in a 52-year-old woman. The patient had a history of massive abnormal uterine bleeding after heavy physical work. A giant cystic mass, originating from the cervix, was found completely filling the upper third of the vagina. The authors combined hysteroscopy examination with ultrasound to assess the cystic mass' localization, origin, and relationship with other organs. With the tentative diagnosis of a giant nabothian cyst, the patient was treated with a simple cervical incision and local drainage. The patient recovered well postoperatively and the diagnosis was confirmed through pathological examination.

Abstract
Psoriasis is one of the most common inflammatory skin conditions affecting both children and adults. Growing evidence indicates that T-helper 17 (Th17) cells and CD4(+) CD25(+) regulatory T (Treg) cells play an important role in the pathogenesis of psoriasis. However, the relationship between Th17 and Treg cells and their dynamic variations in paediatric psoriasis remain unclear. In this study, we found that both Th17 and FoxP3(+) Treg cells and the ratio of Th17 to Treg cell frequency in the peripheral circulation were increased in patients with paediatric psoriasis and were positively correlated with the disease severity. The function of Treg to suppress CD4(+) CD25(-) T cell proliferation and IFN-γ secretion was impaired during the onset of psoriasis. After disease remission, both the Th17 and Treg cell frequencies were decreased, and the suppressive function of the Treg cells was obviously restored. However, neither Treg cells from the disease onset nor those after remission can regulate IL-17 secretion by CD4(+) T cells. These findings will further our understanding of the associations between Th17 and Treg cells in paediatric psoriasis and their influence on disease severity.

Abstract
OBJECTIVE To evaluate the effect of amniotic products after transcervical resection of uterine adhesions (TCRA). METHODS This study was carried out in 57 patients with intensive degree of intrauterine adhesions (IUA) who had been treated by TCRA between Jun. 2013 to Jun. 2014. These patients were devided into two groups randomly. In group amnion, 29 patients were placed amniontic scaffold balloon after TCRA; in group balloon, 28 patients were placed Foley's balloon after TCRA. The two groups' balloons were taken out after TCRA 7 days. All patients were taken artificial cycle treatment. The uterine cavity form and the menstruation of 2 groups were observed in 3 months after TCRA. RESULTS In group amnion, IUA score dropped from 10.1±0.5 preoperatively to 3.2±1.5 postoperative (P<0.01), in group balloon, IUA score dropped from 10.1±0.5 preoperatively to 6.3±2.5 postoperative (P<0.01). In group amnion, the menstrual score increased from 13.3 ± 4.4 preoperatively to 32.6 ± 5.5 postoperative (P<0.01), in group balloon, the menstrual score increased from 11.1±5.8 to 26.5±5.6 (P<0.01). The menstrual improvement of group amnion was better than that of group balloon significantly (P=0.002). In group amnion, the recurrence rate of adhesion was 21% (6/29), in group balloon, the recurrence rate of adhesion was 36% (10/28). There was no significant difference (P=0.248). The pregnancy rate of group amnion was 28% (8/29), the pregnancy rate of group balloon was 21% (6/28). The difference of pregnancy rate in two groups was not significant (P=0.760). CONCLUSION This small sample observation indicate that amniotic products used in the treatment of intensive IUA could improve menstrual, reduce the recurrence of adhesion, but the impovement of the pregnancy rate should be confirmed by large sample observation.

Abstract
OBJECTIVE To investigate the clinical characteristics of pre-malignant and malignant polyps in postmenopausal patients and to evaluate the diagnositic value of hysteroscopy in this disease. METHODS From June 2005 to October 2014, 403 postmenopausal patients with polyps were treated in the Gynecologic Minimally Invasive Center, Beijing Obstetrics and Gynecology Hospital. There were 27 patients including 22 patients with pre-malignant and 5 patients with malignant polyps. All malignant lesions were endometrioid adenocarcinoma. The clinical data were retrospectively analyzed. Based on pathology, the diagnostic value of hysteroscopy was evaluated. RESULTS (1) CLINICAL CHARACTERISTICS: there were 27 cases with pre-malignant and malignant polyps (group 1) and 376 cases with benign polyps (group 2). Compared the two groups, the average age was (60±8) vs (58±6) years old, the period of menopause was (9.8±8.1) vs (8.3±6.9) years. Thirteen cases (48.1%, 13/27) in group 1 and 159 cases (42.3%, 159/376) in group 2 had clinical symptoms including postmenopausal bleeding and vaginal discharge. Twelve cases (44.4%, 12/27) in group 1 and 140 cases (37.2%, 140/376) in group 2 were with hypertension. Five cases (18.5%, 5/27) in group 1 and 43 cases (11.4%, 43/376) in group 2 were with diabetes. The measures above were no significant differences (P>0.05) (2) Ultrasound features: the average thick of endometrium in group 1 and group 2 were respectively (1.3±0.7) and (0.8±0.4) cm, which had statistical significance (t=4.98, P=0.001). (3) Hysteroscopic diagnosis: the average diameters of polyp in group 1 and group 2 were respectively (2.4±1.0) and (1.6±1.0) cm, which had statistical significance (t=2.93, P=0.004). Six cases in group 1 were diagnosed by hysteroscopy including 4 cases of malignant polyp and 2 cases of pre-malignant polyp. The sensitivity, specificity, positive predictive value, negative predictive value and the accuracy were 22.2% (6/27), 100.0% (376/376), 100.0% (6/6), 94.7% (376/397) and 94.8% (382/403), respectively. CONCLUSIONS Pre-malignant and malignant endometrial polyps are more common in the subjects with the larger diameters and the thicker endometrium. All polyps should be under complete resection by hysteroscopy and through pathology examination.

Abstract
OBJECTIVES Fibroblast-like synoviocytes (FLS) are a major component of the hyperplastic synovial pannus, which aggressively invades cartilage and bone during the course of rheumatoid arthritis (RA). Connective tissue growth factor (CTGF or CCN2) is a product of a growth factor-inducible immediate early gene and is involved in cell adhesion, proliferation, and differentiation. However, the role that CTGF plays in FLS proliferation has remained undetermined. The aim of this study was to identify the role of CTGF in regulating the proliferation of FLS derived from patients with RA. METHOD CTGF levels in serum and synovial fluid (SF) were determined by enzyme-linked immunosorbent assay (ELISA). Expression of CTGF in FLS was determined using reverse transcription polymerase chain reaction (RT-PCR). FLS proliferation stimulated by CTGF was measured by thymidine incorporation. The influence of CTGF small interfering RNA (siRNA) on FLS apoptosis was detected by flow cytometry. RESULTS CTGF was overexpressed in serum and SF samples from RA patients compared with samples from normal controls. Elevated levels of CTGF in RA SF promoted the proliferation of FLS. Furthermore, in samples from RA patients, CTGF was found to protect FLS from apoptosis and to sustain the expression of survivin in FLS. The expression of CTGF in FLS can be up-regulated by tumour necrosis factor (TNF)-α. CONCLUSIONS Our findings indicate that CTGF plays a crucial role in the proliferation of FLS in RA and probably contributes to synovial lining cell hyperplasia and eventually to joint destruction in patients with RA.
