Background The rapid diagnosis can win more treating opportunities for patients with fungal keratitis.Even though the fungal culture is the gold standard for the diagnosis of fungal keratitis,it is difficult in early diagnosis due to the long duration of cultivation and false-negative rate.Objective This trial was to explore the clinical value in the rapid diagnosis of fungal keratitis by the combination of corneal scraping with laser scanning confocal microscopy.Methods Corneal scraping and laser scanning confocal microscopy were separately performed in 167 eyes of 167 patients with fungal keratitis.All the eyes were examined by the slit lamp,followed by laser scanning confocal microscope,and then the 10％ KOH corneal smear was examined under the optical microscope.Results The positive rate of diagnosis was 75％ (125/167) by corneal scraping,and that by laser scanning confocal microscopy was 91％ (152/167).The positive rate of examining outcome was significantly higher in laser scanning confocal microscopy than that of corneal scraping (x2 =14.88,P =0.00).The positive results were 114 cases and negative results were 4 cases by two methods,with the concordance rate 70.7％ (118/167).The hyphae or spore were seen in 32 cases by laser scanning confocal microscopy in 42 negative cases by corneal scraping,and in 15 negative cases by confocal laser scanning microscopy,11 positive outcomes were offered by corneal scraping.Conclusions The combined application of corneal scraping with confocal laser scanning microscopy can improve and speed up the diagnosis positive rate of fungal keratitis.

BACKGROUNDDuloxetine is approved for the treatment of generalized anxiety disorder (GAD) in the United States and elsewhere. This study aimed to assess the efficacy, tolerability, and safety of duloxetine in Chinese patients with GAD.

METHODSThis 9-site study consisted of double-blind treatment for 15 weeks either with duloxetine 60 - 120 mg or with placebo. Patients with at least moderately severe GAD and a Sheehan Disability Scale (SDS) global functioning impairment total score ≥ 12 were included in this study. Patients who were randomly assigned to duloxetine received 60 mg for 7 weeks; at that point, for nonresponders the dose was increased to 120 mg for the remaining 8 weeks. The primary efficacy measure was mean change from baseline to endpoint on the Hospital Anxiety and Depression Scale-Anxiety subscale score (HADS-A). Secondary efficacy measures included the Hamilton Anxiety Rating Scale (HAMA), the SDS, and pain measures. Safety and tolerability were assessed.

RESULTSBaseline characteristics did not differ significantly between treatment groups. Mean age of the subjects (n = 210) was 37.6 years, 50.5% were female, and 74.3% completed the 15 weeks treatment. Patients treated with duloxetine had significantly greater improvement compared to placebo on the HADS-A (mean change -6.6 vs. -4.9, respectively, P = 0.022). Improvement in anxiety was greater with duloxetine treatment at 7 weeks and continued through 15 weeks for both the HADS-A and the HAMA total score (0.01 ≤ P < 0.05). Compared with placebo, duloxetine was also associated with greater improvement on most secondary measures, but not on the SDS global functioning score. Nausea, dizziness, and somnolence occurred significantly more frequently as treatment-emergent adverse events with duloxetine treatment compared with placebo treatment.

CONCLUSIONSDuloxetine 60 - 120 mg once daily is effective and well-tolerated for the treatment of patients with GAD in China.

BACKGROUNDPainful physical symptoms (PPS) may present as a component of major depressive disorder (MDD). Their effect in Chinese patients has not been investigated. This analysis reports the changes in disease severity, treatment patterns, quality of life and outcomes in a Chinese cohort according to the presence (PPS+) or absence (PPS-) of painful physical symptoms.

METHODSA subgroup of Chinese patients from a large observational 3-month study of patients from Asian countries and regions of China were classified using the modified Somatic Symptom Inventory (SSI) as PPS+ (mean score >or= 2) or PPS- (mean score < 2). Depression severity was assessed with the Clinical Global Impression of Severity (CGI-S) scale and 17-item Hamilton depression rating scale (HAMD(17)). Pain severity was measured using a visual analogue scale (VAS), while the EuroQoL (EQ-5D) assessed patient well-being. Antidepressants were compared with regard to their efficacy.

RESULTSOf the 299 Chinese patients enrolled in the study, 105 were classified as PPS+ (73/105, 70% women). At baseline, PPS+ patients reported greater pain severity (VAS, mean (SD): 49.56 (26.49) vs. 16.60 (20.99) for PPS-, P < 0.01), were more depressed (HAMD(17), mean (SD): 25.32 (5.47) vs. 23.33 (5.24) for PPS-, P = 0.002) and had poorer quality of life (EQ-5D Health State, mean (SD): 38.48 (22.38) vs. 49.57 (18.54) for PPS-, P < 0.001). PPS+ patients showed less overall improvement in depressive symptom severity (HAMD(17), change from baseline (95%CI): -17.38 (-18.65, -16.12) vs. -19.20 (-20.05, -18.35) for PPS-, P = 0.032; CGI-S, change from baseline (95%CI): -2.85 (-3.11, -2.58) vs. -3.20 (-3.38, -3.02) for PPS-, P = 0.044).

CONCLUSIONSPPS were less frequent than expected compared with previous studies of Asian populations. PPS+ were associated with greater MDD severity and less improvement than PPS- when antidepressants were given.

Abstract: Objective　To analyze the epidemiological characteristics (season, age, gender, mixed infection and clinical manifestations, etc.) of Mycoplasma pneumoniae (MP) infection in children in Hainan Province, so as to provide epidemiological evidence-based medical basis for the prevention and control of MP infection in children in Hainan Province. Methods　The serum IgM antibodies of MP, Legionella pneumophila, Chlamydia pneumoniae, adenovirus, respiratory syncytial virus (RSV), Q fever Rickettsia, parainfluenza virus, influenza A virus and influenza B virus in children with respiratory tract infections (RTIs) who were hospitalized in pediatrics of many hospitals in Hainan Province from March 2012 to February 2020 were detected by indirect immunofluorescence method. The positive serum MP-IgM antibody was defined as MP infection. The epidemiological and clinical data of MP infected cases were analyzed retrospectively. Results　From March, 2012 to February, 2020, a total of 35 731 qualified pediatric inpatients with RTIs in many hospitals in Hainan Province were tested for serum MP-IgM with the total positive rate of 39.12% (13 978/35 731). The yearly positive rates of MP-IgM from 2012 to 2020 were 48.39%, 56.23%, 56.62%, 47.04%, 29.71%, 24.14%, 47.55%, 36.84% and 24.46% respectively. The positive rates of MP-IgM in 2013 and 2014 were significantly higher than those in other years (P<0.05). The positive rate of MP-IgM in summer in Hainan Province was the highest (41.34%) and the lowest in winter (35.77%) (P<0.05). MP infection occurred in all age groups, the positive rate of MP-IgM in children of preschool (51.80%) was significantly higher than that in other age groups (P<0.01), and the positive rate of MP IgM in children of infancy (15.36%) was lower than that in other age groups (P<0.01). The positive rate of MP-IgM in female was 44.77%, which was significantly higher than that in male (35.83%) (P<0.05). MP infection combined with positive IgM of another pathogen accounted for 32.63% (4 561 cases), positive IgM of another two pathogens accounted for 1.26% (176 cases). MP infection was mostly found in pneumonia (68.73%), and the main clinical symptoms were cough (84.72%), fever (51.01%) and wheezing (3.16%). Conclusions　MP is an important pathogen of respiratory tract infection in children in Hainan Province, and infection is more common in children in early school age and early childhood. Mp-specific tests should be performed to identify the pathogen in children suspected of MP infection. In the high incidence season, health education should be strengthened in kindergartens, schools and other places to prevent respiratory tract infection.
