This paper reports 20 patients with cryptococcal meningitis,which were misdiagnosed before anti-fungal therapy,and the majority of them was diagnosed as tuberculous meningitis or viral meningitis.These patients were treated either with amphotericin B or fluconazale alone,or in combina- tion with flucytosine respectively,of the 15 patients could be evaluated,10 were cured(66.7%),2 im- proved(13.3%),3 died(20%),1 relapsed(10%).The mortality rate among the under age group and the aged group was significantly higher than that of the adult group(71.4% vs 23%).It is the authors' experience that in the early stage intrathecal amphotericin B combines with intravenous fluoconazole and changes to oral fluconazole or itraconazole in the later stage may be a valuable approach for cryptococcal meningitis.

Objective To investigate the DNA typing, observe relationship between DNA fingerprinting patterns and serotypes of Cryptococcus neoformans, and find a suitable genotyping standard for Cryptococcus neoformans. Methods Three primers, including CN 1(GTG) 5, CN 2(GACA) 4 and CN 3(GATA) 4, were used to distinguish variations among strains of C.neoformans. Results The distinguishable fingerprinting bands for serotype of C.neoformans were yielded by primer CN 2. Using this primer, of 24 clinical and environmental isolates of serotype A of C.neoformans and 8 standard strains investigated by PCR, 20 strains produced complete identical fingerprinting patterns, the other 4 strains had different fingerprinting patterns. 2 strains of serotype B and C yielded indistinguishable fingerprinting patterns. Conclusions ①The majority of strains of serotype A had similar and stable fingerprinting patterns. ②Some strains of serotype B and C had an indistinguishable fingerprinting patterns. ③The same serotype strains from different sources may produce different DNA fingerprinting patterns. ④The DNA fingerprinting is a rapid, simple and feasible method for identifying Cryptococcus neoformans.

Objective To explore the application of continuing nursing model in life of puerperae with preterm infants and evaluate its effects.Methods Based on continuous nursing model of Ahmadi,puerperae's continuing nursing program was constructed.Randomized controlled trail design was used,and totally 110 puerperae in a hospital in Beijing were recruited from August 2016 to March 2017.The experimental group received continuing nursing intervention model,and the control group received routine nursing care.Parenting knowledge and psychological evaluation of the two groups were collected 3 days before discharge,1 month,3 months and 6 months after discharge.Results Ninety-eight puerperae completed the study.In the experimental group,the score of parenting knowledge was higher than that of the control group(P＜0.01),and the total score of mental health assessment and scores of depression and anxiety were lower than those in the control group (P＜0.05).Conclusion Puerperae's continuing nursing program based on the continuous nursing model of Ahmadi improved maternal ability and positive emotion,and promoted quality of life.

Objective At present , there is only a small amount of survey scale of caregivers′cognitive level on continuous nursing care for premature infants , which had not been subject to stringent testing of reliability and validity .This paper aims at developing a suitable survey scale of caregivers′cognitive level oncontinuous nursing care for 0-1 year premature infants , and testing its reliability and validity. Methods Convenience sampling method was used and totally 495 caregivers of premature infants of Army General Hospi-tal affiliated BaYi Children hospital from April to August 2016 has been investigated .After we had preliminary content of the question-naire, two-round Delphi consultations were used to identify the draft of the scale , and the reliability and validity were tested .

Objective To investigate genetic relationships among five serotypes of two variants of Cryptococcus neoformans. Methods PCR mediated DGGE (denaturing gradient gel electrophoresis) and sequence analysis of 28S rDNA of C. neoformans were performed in ten reference strains, C. neoformans capsular-deficient strain CAP10, and nineteen clinical isolates from non-HIV patients. Results The results of DGGE and analysis of nucleotide sequences of 28S rDNA showed identical patterns and nucleotide sequences in the serotype A and D of C. neoformans var. neoformans, which were distinct from the serotye B and C of C. neoformans var. gattii. The patterns and sequences of serotype AD coincided with those of C. neoformans var. gattii. The patterns and nucleotide sequences of C. neoformans capsular-deficient strain CAP10 (serotype D) and serotype A and D were identical. Of the nineteen clinical isolates, seventeen had patterns of serotype A and D, and the others had patterns of serotype B and C. Conclusions PCR mediated DGGE integrated with sequence analysis of 28S rDNA is a valuable tool for the classification of C. neoformans. The clinical isolate of C. neoformans var. neoformans is predominant in Chinese non-HIV patients. Serotype AD is genetically close to C. neoformans var. gattii rather than C. neoformans var. neoformans. The data seem not to be in favor of previous study that serotype A, C. neoformans var. grubii, is a new variant of C. neoformans.

Objective To investigate the effects of heat-inactivated Cryptococcus neoformans(H-CN)on an experimental murine model of meningoencephalitis and on IL-1?,IFN-?and TNF-?gene ex-pression on the brain and spleen.Methods An experimental murine model of intracerebral infection with C.neoformans was established.Mice were divided into H-CN-treated group and control group.The brain and spleen of two groups were collected to obtain total RNA,and IL-1?,IFN-?and TNF-?were detected by RT-PCR method.After intracerebral challenging with lethal doses of C.neoformans,the survival time and colony forming units(cfu)of C.neoformans in the brain of two group were observed.Results The survival time was prolonged,and cfu of C.neoformans were decreased in the brain of H-CN-treated group in com-parison with those of control group.Expression of IL-1?was positive,and IFN-?and TNF-?negative in the brain tissue of H-CN-treated mice;while expression of IL-1?,IFN-?and TNF-?was all negative in the control mice,as indicated by RT-PCR.Expression of3cytokines,IL-1?,IFN-?and TNF-?was all positive in the spleen tissue of both groups,suggesting that there was no significant difference in the levels of cytokine gene transcripts in both groups.Conclusion These findings suggest that murine resistance to central nervous system infection of C.neoformans be enhanced by intracerebral administration of H-CN,and anti-cryptococcal mechanism probably involves a local cytokine IL-1?elicitated by H-CN in central nerve system.

Guangdong province is experimenting with a model composed of various types of medical alliances, having achieved initial success with some of them and preliminarily has formed a holistic governance pattern. Experiences behind such initial success lied in a coordinated top-level design, reasonable and classified guidance, leader role of key governance subjects, and the construction of a telemedical system. However, as analyzed from the angle of collaborative governance, existing medical alliances have not yet formed a community of services, that of responsibility, that of interests, and that of services. In this consideration, the authors recommended to strengthen the collaborative governance of such alliances by respective governance subjects based on the theories of integrated medical service system and collaborative governance, eventually forming an integrated medical and health service system.

Objective:To analyze the prognostic risk factors of patients with sepsis and the clinical characteristics of patients with septic myocardial injury.Methods:A retrospective study was conducted. The clinical data of 300 patients with sepsis admitted to emergency department of Zhongshan Hospital of Fudan University from September 2017 to June 2020 were enrolled, including basic information, blood test indicators and auxiliary inspection indicators. The patients were grouped according to myocardial injury and the clinical characteristics of patients with septic myocardial injury were analyzed. According to 28-day prognosis, they were divided into survival group and non-survival group. The differences in various indicators between the two groups were compared, and binary Logistic regression was used to explore independent risk factors for death in patients with sepsis.Results:In 300 patients, 47 patients were excluded for previous heart disease or lack of the main inspections, and 253 patients were enrolled finally. ① Myocardial injury occurred in 136 out of 253 patients (53.8%), and 117 without myocardial injury. Compared with the non-myocardial injury group, the myocardial injury group had higher blood white blood cell count [WBC (×10 9/L): 9.7 (6.7, 13.4) vs. 8.3 (5.4, 12.2)] and procalcitonin [PCT (μg/L): 0.61 (0.18, 4.63) vs. 0.23 (0.09, 0.99)] at admission, and more Staphylococcal infections (17.6% vs. 2.6%), more arrhythmia (sinus tachycardia: 30.9% vs. 23.1%), more ST-T changes (26.5% vs. 23.1%), lower left ventricular ejection fraction [LVEF: 0.60 (0.54, 0.65) vs. 0.62 (0.60, 0.66)], higher pulmonary artery systolic pressure [PASP (mmHg, 1 mmHg = 0.133 kPa): 38.0 (32.2, 46.0) vs. 33.0 (30.0, 40.2)], and worse prognosis (28-day mortality: 44.1% vs. 6.0%, all P < 0.05). Logistic regression analysis showed that PCT increased [odds ratio ( OR) = 1.039, 95% confidence interval (95% CI) was 1.018-1.060, P < 0.01], LVEF decreased ( OR = 0.828, 95% CI was 0.729-0.941, P < 0.01) and sinus tachycardia ( OR = 3.512, 95% CI was 1.417-8.702, P < 0.01) were clinical characteristics of septic patients with myocardial injury. ② A total of 186 of the 253 patients survived, and 67 died with 28-day mortality of 26.5%. Compared with the survival group, non-survival group had higher myocardial markers and inflammation markers at admission [cardiac troponin T (cTnT, μg/L): 0.06 (0.02, 0.17) vs. 0.02 (0.01, 0.05), N-terminal pro-brain natriuretic peptide (NT-proBNP, ng/L): 3 037.0 (1 308.7, 12 033.7) vs. 893.9 (272.8, 2 825.5), creatine kinase (CK, U/L): 144.5 (57.5, 660.8) vs. 89.5 (47.8, 201.0), WBC (×10 9/L): 10.5 (6.7, 14.6) vs. 8.6 (6.0, 12.0), C-reactive protein (CRP, mg/L): 89.2 (54.8, 128.5) vs. 63.8 (19.3, 105.6), PCT (μg/L): 2.13 (0.31, 11.79) vs. 0.28 (0.10, 1.25), all P < 0.05], and more sinus tachycardia and atrial arrhythmia (41.8% vs. 22.0%, 29.9% vs. 17.7%, both P < 0.05). Logistic regression analysis showed that cTnT increased ( OR = 2.115, 95% CI was 1.189-5.459, P < 0.05), sinus tachycardia ( OR = 2.557, 95% CI was 1.103-5.929, P < 0.05) and atrial arrhythmia ( OR = 2.474, 95% CI was 1.025-5.969, P < 0.05) were independent risk factors for 28-day death in patients with sepsis. Conclusions:Myocardial injury is an independent risk factor for death in patients with sepsis. PCT elevation, LVEF decreased and sinus tachycardia are main characteristics of patients with septic myocardial injury, which should attract clinical attention.

Objective:To compare the predictive value of the HEART, TIMI and GRACE scores for major adversecardiovascular events (MACEs) at 7 and 28 days in patients with actue non-ST-segment elevation myocardial infarction (NSTEMI).Methods:More than 12 000 patients with chest pain from the Emergency Department of Zhongshan Hospital Affiliated to Fudan University from October 2017 to October 2018 were studied, including 566 patients with cardiogenic chest pain, 105 patients with ST-segment elevation myocardial infarction (STEMI) excluded and 15 patients lost to follow-up. Finally, 109 patients with NSTEMI and 337 non-myocardial patients with cardiogenic chest pain were enrolled. NSTEMI patients were divided into subgroups according to whether MACEs occurred. LSD t-test, Mann-Whitney U test or χ2 test were used to analyze and compare the differences between the two subgroups about the baseline data, clinical data, HEART, TIMI and GRACE scores at the time of visit. Multivariate logistic regression analysis was used to explore the independent factors of MACEs at 7 and 28 days. And the predictive values of different scores for 7-day MACEs and 28-day MACEs were compared in NSTEMI patients through the receiver operating characteristic (ROC) curve. Results:Compared NSTEMI patients with non-myocardial patients with cardiogenic chest pain, we found a statistically significant differences in sex, past history of coronary heart disease,≥3 risk factors for atherosclerosis, electrocardiogram, high-sensitivity troponin T (hs-cTnT), creatinine value, past history of myocardial infarction, HEART score, TIMI score and GRACE score. In further subgroup analysis of NSTEMI patients who were divided according to whether MACEs occurred, we found previous history of stroke and increased hs-cTnT were statistically different in 7 days after the onset of the disease. The multivariate analysis showed that the previous history of stroke and increased hs-cTnT were independent factors for the occurrence of MACEs at 7 days after the onset of NSTEMI; The previous history of stroke and increased hs-cTnT, electrocardiogram ST segment depression and TIMI score were statistically different at 28 days after the onset of NSTEMI. The multivariate analysis showed that the previous history of stroke and TIMI score were independent factors for the occurrence of MACEs at 28 days after the onset of NSTEMI patients. ROC curve indicated that the predictive value of TIMI score (AUC=0.715, 95% CI: 0.482-0.948) was better than HEART (AUC=0.659, 95% CI: 0.414-0.904) and GRACE scores (AUC=0.587, 95% CI: 0.341-0.833)in predicting MACEs in NSTEMI patients. Conclusions:HEART score, TIMI score and GRACE score can be used to evaluate NSTEMI patients. There is an independent predictive value on TIMI score for the occurrence of 28-day MACEs in NSTEMI patients.

Objective:To analyze the correlation between gastric disharmony and daily eating behaviors in college students, and to provide intervention measures for improving gastric disharmony among college students.Methods:From April 10 to 30, 2021, 3 825 college students from five Chinese medicine colleges and universities in China were selected for this study using the multi-level sampling method. The information regarding college student's general situation, daily eating behavior, and stomach disharmony was collected by questionnaire.Results:A total of 3 700 valid questionnaires were collected, with an effective response rate of 96.73%. The average age was (20.0 ± 3.0) years, and 66.41% of college students included in this study were female. Students with different characteristics had different gastric disharmonies and eating behaviors, and gastric disharmony was correlated with eating behavior. Multivariate analysis results showed that snacking ( OR = 1.11, 95% CI: 1.02-1.21), partial eclipse ( OR = 1.12, 95% CI: 1.00-1.26), picky eaters ( OR = 1.23, 95% CI: 1.08-1.41), and supper ( OR = 1.19, 95% CI: 1.04-1.36) were positively correlated with gastric disharmony. Eating regular meals ( OR = 0.86, 95% CI: 0.79-0.94) and 80% fullness ( OR = 0.89, 95% CI: 0.81-0.98) were negatively correlated with gastric disharmony. Conclusion:Poor eating behaviors may be an important factor leading to gastric disharmony.
