Abstract
Current medical treatments for endometriosis-associated pain (EAP) have limitations, including symptom recurrence and hormonal side effects. For this reason, it is important to elucidate any alternative or complementary treatments available, while Chinese herbal medicine (CHM) shows potential to be this treatment. This study aims to provide evidence for the efficacy and safety of CHM for EAP. Randomized control trials comparing CHM to other treatments for EAP in women with endometriosis were considered eligible, and they were searched for in Medline, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov, as well as in the Chinese databases Sino-Med and CNKI, from inception to October 2021. Numerous outcomes were put through meta-analysis using a weighted mean difference and a 95% CI, and the results of dichotomous data were presented as a pooled RR with a 95% CI. A total of 34 eligible studies with 3389 participants were included. Compared with no treatment, there was a statistically significant pooled benefit of CHM on dysmenorrhea at the end of 3-month treatment, and these effects continued for 3 months, but not 9 months, after treatment. Compared with conventional therapy, a significant difference was found in the levels of pelvic pain with a lower rate of hot flush and irregular vaginal bleeding at the end of treatment for 3 months, but not after treatment. Comparing combined treatment with CHM and conventional therapy with conventional therapy alone, significant decreases were found in dysmenorrhea, dyspareunia, and pelvic pain after a 3-month treatment cycle, and in dysmenorrhea after a 4-month treatment cycle with a lower hot flash rate. In conclusion, CHM, used alone or in combination with conventional therapies, appears to have benefits in relieving EAP with fewer side effects than traditional treatment.

Abstract
BACKGROUND AND AIMS Intracranial arterial stenosis (ICAS) is one of the most common causes of stroke, especially in Asians. Hyperuricemia has been associated with an increased risk of comorbidities such as metabolic syndrome or cardiovascular diseases. However, there are few studies focusing on the association between serum uric acid (SUA) levels and asymptomatic ICAS. The aim of this study was to explore the association between SUA and the prevalence of ICAS in middle-aged Korean health screening examinees. METHODS AND RESULTS A cross-sectional study was performed on 9417 males and 7755 females who underwent a comprehensive health examination including transcranial Doppler (TCD) ultrasonography. The association of SUA and ICAS was analyzed using multivariate logistic regression. The prevalence of ICAS among the total examinee population was 3.55%. In females, the multivariate-adjusted odds ratio for ICAS was 1.52 (confidence interval 1.13-2.04) in the 3rd quartile of SUA and 1.45 (1.05-2.00) in the highest quartile, compared to the reference (P for trend 0.008). This trend was evident in all clinically relevant subgroups evaluated, including women with low inflammation status. SUA was not significantly associated with the prevalence of ICAS among males. In a sensitivity analysis, the multivariate-adjusted odds ratio of middle cerebral artery stenosis in females was 1.60 (1.09-2.37) in the highest quartile compared to the reference (P for trend 0.023). CONCLUSIONS Higher SUA level was associated with increased risk of ICAS among middle-aged females but not males. A further cohort study is warranted to elucidate the effect of SUA on asymptomatic ICAS.

Abstract
Luteinizing hormone (LH) is crucial for the development of follicular growth and oocyte maturation, especially in the management of poor ovarian responders (PORs). This study presents the results of a prospective double-blinded randomized study to compare the effect of mid-follicular phase recombinant LH (rLH) supplementation with urinary human chorionic gonadotrophin (uHCG) supplementation when using a fixed gonadotrophin-releasing hormone (GnRH) antagonist protocol in IVF cycles. A total of 49 women with poor ovarian response (POR) according to the Bologna criteria were recruited. This study showed no statistically significant difference in cycle cancellation rates, numbers of oocytes retrieved per cycle initiated, fertilization rates, the numbers of embryos obtained per cycle initiated, implantation, clinical pregnancy and live birth rates, although the live birth rate per cycle initiated in the uHCG group (29.2%) was 3.6 times that of the rLH group (8.0%). Further studies are required to verify if uHCG supplementation produces better clinical outcomes compared with rLH in women with POR.

Abstract
BACKGROUND AND PURPOSE Pulmonary fibrosis (PF) is a progressing lung injury initiated by pulmonary inflammation (PI). Bleomycin (BLM) is the most common pathogenesis of PF through early PI and extensive extracellular matrix deposition. This study is aimed to determine whether NO-releasing KMUP-1 inhibits PI and PF, and if so, the benefits of KMUP-1S resulted from simvastatin (SIM)-bonding to KMUP-1. EXPERIMENT APPROACH C57BL/6 male mice were intra-tracheally administered BLM (4 U/kg) at day 0. KMUP-1 (1-5 mg/kg), KMUP-1S (2.5 mg/kg), SIM (5 mg/kg), Plus (KMUP-1 2.5 mg/kg + SIM 2.5 mg/kg), and clarithromycin (CAM, 10 mg/kg) were orally and daily administered for 7 and 28 days, respectively, to mice, sacrificed at day-7 and day-28 to isolate the lung tissues, for examining the inflammatory and fibrotic signaling and measuring the cell population and MMP-2/MMP-9 activity in broncholaveolar lavage fluid (BAL). KEY RESULTS KMUP-1 and KUP-1S significantly decreased neutrophil counts in BAL fluid. Fibroblastic foci were histologically assessed by H&E and Masson's trichrome stain and treated with KMUP-1 and references. Lung tissues were determined the contents of collagen and the expressions of TGF-β, α-SMA, HMGB1, CTGF, eNOS, p-eNOS, RhoA, Smad3, p-Smad3, MMP-2 and MMP-9 by Western blotting analyses, respectively. These changes areregulated by NO/cGMP and inhibited by various treatments. KMUP-1 and KMUP-1S predominantly prevented HMGB1/MMP-2 expression at day-7 and reduced TGF-β/phosphorylated Smad3 and CTGF at day-28. CONCLUSIONS AND IMPLICATIONS KMUP-1 and KMUP-S restore eNOS, inhibit iNOS/ROCKII/MMP-2/MMP-9, attenuate histologic collagen disposition and reduce BALF inflammatory cells, potentially useful for the treatment of BLM-lung PF.

Abstract
BACKGROUND Hepatitis B virus (HBV) infection remains a global public health problem and it is an important cause of acute, chronic and fulminant hepatitis, liver cirrhosis and hepatocellular carcinoma. The prevalence of HBV infection in Hong Kong over the past decade remained unchanged at 10%, despite the implementation of universal neonatal and availability of adult vaccination. We suspect that the current state of affairs is attributable to inadequate awareness and knowledge of HBV transmission and prevention in the general population, resulting in a low rate of uptake of HBV vaccination by the lay public. Therefore, we have embarked in this study to evaluate the awareness and knowledge on HBV infection in our local Chinese population, their attitude on the prevention of horizontal transmission of HBV, and the use of HBV vaccination, especially in those who were born before the era of universal neonatal vaccination. METHODS The factors associated with HBV screening, vaccination uptake, and knowledge were examined in a face-to-face questionnaire survey on a group of adult Chinese in Hong Kong. RESULTS Within this group, 14% was considered to have good knowledge for HBV infection, and 26% had HBV vaccination. Age, occupation, having children, and family monthly income, are independent factors associated with vaccination. CONCLUSION This study suggests insufficient public awareness of HBV infection in the Hong Kong Adult Chinese population.

Abstract
OBJECTIVE. To study the presentations, diagnoses, and outcomes in adolescents with menstrual disorders. DESIGN. Prospective cohort study. SETTING. Paediatric and Adolescent Gynaecology Clinic, Hong Kong. PARTICIPANTS. A total of 577 adolescents aged 14 to 19 years. MAIN OUTCOME MEASURES. The presentations and diagnoses of adolescents with menstrual disorders were reviewed and their menstrual outcomes determined by a telephone survey. RESULTS. In all, 47% presented with menorrhagia, prolonged menstruation, and short menstrual cycles; 27% had secondary amenorrhoea, 12% had dysmenorrhoea, 11% had oligomenorrhoea, and 3% had primary amenorrhoea. Significant diagnoses included congenital genital tract anomalies, premature ovarian failure, anorexia nervosa, and polycystic ovarian syndrome. Polycystic ovarian syndrome was diagnosed in 16% of the cohort. In all, 24% of these 577 patients had abnormal menstrual cycles 4 years later. Direct logistic regression analysis indicated a cycle length of more than 35 days at presentation (adjusted odds ratio=2.8; 95% confidence interval, 1.8-4.5), previous diagnosis of polycystic ovarian syndrome (adjusted odds ratio=2.0; 95% confidence interval, 1.1-3.4), and current body mass index of 23 kg/m(2) or higher (adjusted odds ratio=1.8; 95% confidence interval, 1.0-3.0) were risk factors for persistently long menstrual cycle exceeding 35 days. Adolescents who were screened out with a definitive diagnosis after initial assessment were at low risk of persistently long menstrual cycles at follow-up (adjusted odds ratio=0.3; 95% confidence interval, 0.1-0.8). CONCLUSIONS. Adolescent menstrual disorders should not be ignored. Long cycle, diagnosis of polycystic ovarian syndrome at first consultation, and a current body mass index of 23 kg/m(2) or higher were statistically associated with persistent problems.

Abstract
Most IMRT techniques have been designed to treat targets smaller than the field size of conventional linac accelerators. In order to overcome the field size restrictions in applying IMRT, we developed a two isocenter IMRT technique to treat long volume targets. The technique exploits an extended dose gradient throughout a junction region of 4-6 cm to minimize the impact of field match errors on a junction dose and manipulates the inverse planning and IMRT segments to fill in the dose gradient and achieve dose uniformity. Techniques for abutting both conventional fields with IMRT ('Static + IMRT') and IMRT fields ('IMRT + IMRT') using two separate isocenters have been developed. Five long volume sarcoma cases have been planned in Pinnacle (Philips, Madison, USA) using Elekta Synergy and Varian 2100EX linacs; two of the cases were clinically treated with this technique. Advantages were demonstrated with well-controlled junction target uniformity and tolerance to setup uncertainties. The junction target dose heterogeneity was controlled at a level of +/-5%; for 3 mm setup errors at the field edges, the junction target dose changed less than 5% and the dose sparing to organs at risk (OARs) was maintained. Film measurements confirmed the treatment planning results.

Abstract
BACKGROUND AND PURPOSE The clinical presentation of frontotemporal dementia (FTD) is often asymmetrical in terms of both its clinical features and atrophy on MRI. Asymmetry in the lateral ventricle size on structural neuroimaging in FTD patients may have clinical significance. However, this has not been systematically investigated yet. This study compares the ventricular asymmetry seen on MRI with that of the asymmetric glucose metabolism using FDG-PET in patients with FTD. METHODS Nineteen FTD patients who underwent both brain MRI and FDG-PET were retrospectively selected. As control groups, 23 and 11 age and sex-matched healthy normal subjects underwent either brain MRI or FDG-PET, respectively. The ventricular asymmetry index (VAI) was obtained in two ways: by visual rating (VAI-V) and by measuring the lateral ventricular volumes (VAI-ROI). The hemispheric asymmetry of the glucose metabolism on FDG-PET (MAI) was assessed in three ways: 1) by visual rating (MAI-V), 2) by counting the FDG activity of each hemisphere on normalized and smoothed PET images (MAI-ROI) and 3) by counting the number of voxels with significant hypometabolism based on statistical parametric mapping results (MAI-SPM). RESULTS The VAIs on MRI (VAI-V and VAI-ROI) were highly correlated, as were the MAIs (MAI-V, MAI-ROI, and MAI-SPM) on FDG-PET. More importantly, the VAIs on MRI and the MAIs on FDG-PET showed high correlation. CONCLUSIONS Ventricular asymmetry in FTD patients was common (78.9%) and there was a high correlation between the ventricular structural asymmetry and the hemispheric metabolic asymmetry. Therefore, it would be reasonable to interpret that the hemisphere with larger ventricle on MRI in FTD patients is undergoing a more active degenerative process.

Abstract
We report a 62-year-old man with non-convulsive status epilepticus (NCSE) presenting as a progressive aphasia that developed insidiously over 5 weeks. On video-EEG monitoring, aggravation of the aphasia coincided with occurrence of seizure activities arising from the left fronto-temporal area. Brain MRI was noncontributory but a fluorodeoxyglucose-PET scan revealed a hypometabolism in the left anterior temporal area. Following anticonvulsant treatment, aphasia recovered gradually over several weeks despite prompt resolution of epileptic discharges on EEG. Our patient's findings, gradual onset of isolated aphasia with gradual resolution after initiation of treatment, may differ from previously reported cases with aphasic status epilepticus because their aphasia showed abrupt onset and rapid resolution with anticonvulsant medication.

Abstract
Excretion of enterovirus (EV) may persist for months after an EV infection; the exact duration of excretion, however, is not yet known. Twelve children who were infected with EV between September 1998 and June 1999 were enrolled into this study. The patients included 4 boys and 8 girls, aged from 1 month to 5 years. Six patients were asked to join this virus isolation program, and the other 6 were followed-up regularly. Only 2 of the patients were infected with EV 71. To delineate the duration of EV shedding in each case, throat swabs for virus isolation were performed every 1 or 2 weeks for at least 1 month, and stools were analyzed for at least 2 months following the same schedule. After the infection, EV was identifiable in the throat in 4 patients for 1 to 2 weeks. Excretion of EV through stool was evidenced for up to 7 weeks in 6 patients, 8 weeks in 3, and 11 weeks in 1. In the 2 patients who failed to show up for follow-up visits from the 7th week, excretion of EV through stool was recorded for at least 7 weeks. Different serotypes of EV could be isolated from the same patient who was not experiencing febrile illness in 2 instances in a series of virus cultures. Coexistence of vaccine poliovirus and non-polio EV, both isolated from stool, was evidenced in 2 patients. Results from this study suggest that EV may not be identified from the throat 2 weeks after the infection, but its excretion through stool can persist for up to 11 weeks. This study also demonstrated that subclinical EV coinfection could occur, and that live vaccine poliovirus did not interfere with the invasion of other non-polio EV.

Abstract
OBJECTIVES To compare enterovirus 71 (EV 71) with coxsackievirus A16 (Cox A16) clinical illness in patients at Chang Gung Children's Hospital during Taiwan's enterovirus epidemic of 1998. METHODS With the use of the immunofluorescence assay and neutralization test, 177 cases of EV 71 and 64 cases of Cox A16 illness were confirmed from April to September, 1998. The clinical signs and symptoms, complications and case fatality rates were compared. RESULTS Three-fourths of the cases were younger than 3 years of age, and the ratio of males to females was 1.3 in the EV 71 group and 1.2 in the Cox A16 group. In the EV 71 group 120 (68%) cases were uncomplicated, including 94 cases of hand, foot and mouth disease and 15 cases of herpangina, and 57 (32%) cases had complications, including 13 (7.3%) cases of aseptic meningitis, 18 (10%) cases of encephalitis, 4 (2.3%) cases of polio-like syndrome, 8 (4.5%) cases of encephalomyelitis and 12 (6.8%) cases of fatal pulmonary edema. Fourteen (7.9%) patients died, including 12 cases of pulmonary edema and 2 cases of encephalitis; seven (4%) patients had sequelae. By contrast, 60 (94%) of the 64 cases of Cox A16 infection were uncomplicated and only 4 (6.3%) cases were complicated by aseptic meningitis; no fatalities or sequelae were observed. By multivariate analysis vomiting (P = 0.01) and fever higher than 39 degrees C plus lasting longer than 3 days (P = 0.02) were significantly more frequent in the EV 71 group. CONCLUSION EV 71 illness is more severe with significantly greater frequency of serious complications and fatality than is illness caused by Cox A16.

Abstract
In order to elucidate the prevalence of individual complications and its relation to the age of patients and to the duration of diabetes in Korean diabetics, the authors observed 1442 diabetic patients (816 males and 626 females, with the age range 11 to 86) who were treated at the Chonnam University Hospital from 1982 to 1986. The results were as follows: 1) The overall prevalence of the diabetic complication was 38.6%, and prevalence of age group under 20 was 31%, and 30%, 24%, 31%, 45% and 49% for 3rd, 4th, 5th, 6th and over 6th decade, respectively. An increase in incidence after 40 years of age was noted. Among all complications, cardiovascular complication (25.7%) had the highest incidence while others were in the following order neuropathy (24.2%), retinopathy (24.0%), nephropathy (15.5%), infection (10.5%), and acute diabetic coma (2.1%). The prevalence of complication was not significantly different in sexes, however, increasing prevalence was noted after 40 years of age. 2) In neuropathy, peripheral type was the most common, and background retinopathy was frequently observed. Proliferative diabetic retinopathy was reported in 22 cases from the total of 26 cases of retinopathy in patients over 40 years of age. Seventy percent of patients with nephropathy had proteinuria with no significant in BUN and creatinine levels; and the dominant groups was males over 40 years of age. 3) Hypertension was the most common cardiovascular complication with no gender difference, while atherosclerosis and cerebral thrombosis were frequently observed in males over 40 years of age. Foot gangrene was seen in all age groups but it was especially prevalent in males in their sixties. 4) Among infectious complications, pulmonary tuberculosis had the highest frequency (21.6%), and skin infection (19.2%), and urinary tract infection (17.4%) were common complications; also emphysematous pyelonephritis was found in 2 cases. These results suggest that chronic diabetic complications relate to the duration of the disease and to the age of patients. The prevalence rate of diabetic complications should be evaluated considering factors such as racial and socioeconomic conditions, and possible risk factors for individual complications. With the clinical use of insulin and antibiotics, mortality from acute diabetic complications, such as coma or infections, showed significant decrease in contrast to the increasing prevalence of late complications which became the major causes of fatality in diabetics. Although these chronic complications were rising, determination of the exact prevalence in the population was difficult and varied in every report due to their occurrence in various combinations. This study was performed to elucidate (1) the prevalence of individual complication and (2) its relation to the age of patients and (3) its relation to the duration of diabetes in korean diabetics.
