OBJECTIVE: To study the efficacy of Xiaoyao capsule in improving the clinical symptoms of sleep and mood disorders during recovery from coronavirus disease 2019 (COVID-19). METHODS: The study cohort comprised 200 patients with sleep and mood disorders during recovery from COVID-19. Patients were randomized into the control group and the experimental group in a 1:1 ratio by blocked randomization. The patients received either Xiaoyao capsule (experimental group) or a placebo Xiaoyao capsule (control group) for 2 weeks. The improvements in the Traditional Chinese Medicine (TCM) syndrome scales, total effective rates, and disappearance rates of irritability, anxiety, and poor sleep were compared between the two groups. RESULTS: The TCM syndrome pattern scales, total effective rates, and disappearance rates of irritability, anxiety, and poor sleep did not significantly differ between the experimental group versus the control group in the full analysis set and the per protocol set after 1 and 2 weeks of treatment ( > 0.05). CONCLUSIONS: Xiaoyao capsule do not significantly improve the clinical symptoms of sleep and mood disorders in patients in recovery from COVID-19.

Reflection on Improving College Students’ Health Literacy from the Perspective of Health Ethics / 中国医学伦理学

Contemporary college students have low levels of health literacy, facing problems such as weak awareness of health care, unhealthy diet habits, insufficient physical activity, and inadequate emergency response to public health emergencies. The reasons may be related to weak personal awareness of health literacy, imperfect health education system, shortage of health literacy education talents, lack of family health literacy education, and the insufficient social investment in health literacy cultivation. Faced with this current situation, the government, universities, families, individuals, and society should respond to the call of "Healthy China 2030" Plan Outline, regard improving college students’ health literacy level as their own responsibility, help them eliminate or reduce the risk factors affecting health, improve their health literacy level and quality of life, and contribute to the Healthy China strategy.

Risk assessment and analysis of Traditional Chinese Medicine intervention in coronavirus disease.

OBJECTIVE: To explore the advantages of Traditional Chinese Medicine (TCM) in "prevention" and "control" of coronavirus disease 2019 (COVID-19) pandemic. METHODS: In this paper, we wish to estimate the effect on the virus transmission of scenarios assuming TCM were used to build the first defense line at the very early stage of the spread in Wuhan. We therefore first developed a classic susceptible infected removed (susceptible infected removed, SIR) transmission model based on the national data in China and then updated it to a TCM-SIR model to assess the potential impact of such assumptions, i.e. the underlying risk of lives lost and social economy loss. RESULTS: (a) With the nationwide community lockdown, the risk value was from 90 000 to 250 000 without TCM intervention and the risk value was from 70 000 to 220 000 with TCM intervention; (b) Based the risk assessment method, we forecasted that the infections peak would be 58016 without TCM intervention, which happened on February 17 2020. However, the infections peak would be 45713 with TCM intervention, which happened on 16 February 2020. CONCLUSIONS: The adoption of nationwide community lockdown is conducive to timely control the epidemic and protect people's lives and safety. At the same time, we can get lower infections if TCM intervention can be considered. We can also get the benefits from TCM prevention of COVID-19 pandemic by the basic number of infections.

Expression of CUL7 and CCDC8 proteins in normal mouse tibial growth plate / 中华内分泌代谢杂志

To investigate the changes of expression location and amount of CUL7 and CCDC8 proteins in the growth plate of normal mice aged 0-4 weeks, and to clarify the roles of CUL7 and CCDC8 proteins in the proliferation and differentiation of tibia growth plate of mice. The expression location and levels of CUL7 and CCDC8 proteins in the tibial growth plate of normal mice aged 0-4 weeks were observed with immunohistochemical staining. CUL7 protein was expressed in the cell cytoplasm and membrane in three zones of tibial growth plate three bands at 0-4 weeks. The expression level and total expression level of CUL7 protein in each zone of growth plate decreased gradually with the increase of week of age( F=369.61, P=0.001). The expression of CUL7 protein decreased most significantly in the proliferative zone, followed by the stationary zone and the hypertrophic zone. CCDC8 protein was mainly expressed in proliferation zone and hypertrophic zone cell membrane and nuclear membrane of growth plate at 0-2 weeks, and mainly expressed in hypertrophic zone cell membrane and nuclear membrane at 3-4 weeks. The expression of CCDC8 protein in the proliferating zone changed inversely with week of age, and the expression of CCDC8 protein in the hypertrophic zone increased over 4 weeks( F=453.67, P<0.001). The total expression of CCDC8 protein in growth plates decreased with the increase of week of age.The expression levels of CUL7 and CCDC8 decreased with the increase of week of age, suggesting that CUL7 and CCDC8 may promote the proliferation and differentiation of growth plate chondrocytes.

Objective:To investigate the effect of free anterolateral thigh perforator flap on repair of bone exposure of diabetic foot ulcer.Methods:From Sep. 2016 to Dec. 2019, free anterolateral thigh perforator flap was used to repair 19 cases of diabetic foot ulcer with bone exposure. The area of the flap ranged from 5.0 cm×7.0 cm to 10.0 cm×16.0 cm. The donor site of the flap was sutured directly. The patients were followed up regularly by outpatient and telephone.Results:18 of the 19 cases survived completely, in one case, most of the flap were necrotic, healed after second stage skin grafting; 5 flaps developed edema due to low albumin, and healed after stitches removal, dehydration, albumin supplement and secondary suture and antibiotic replacement. Through 6 to 24 months of follow-up study we concluded that flap transfer could functionally and morphologically repair wounds with soft tissue defect and infection.Conclusion:Free anterolateral thigh perforator flap is effective in repairing diabetic foot ulcer and can effectively reduce disability rate.

Clinical characteristics and microflora analysis of back abscess in patients with type 2 diabetes mellitus / 中华内分泌代谢杂志

Objective:To retrospectively analyze clinical characteristics, flora distribution characteristics, and antimicrobial sensitivity of type 2 diabetic patients with back abscess.Methods:The clinical data of patients with type 2 diabetes mellitus and back abscess were collected from Endocrinology Department of Henan Provincial People′s Hospital from October 2017 to April 2020. The results of bacterial culture and drug sensitivity test were analyzed, antibiotics were given to treat infection, incision and debridement of abscess were performed according to the situation of abscess, drainage of abscess cavity or continuous negative pressure suction was given when necessary, and the clinical outcome was recorded.Results:A total of 12 type 2 diabetic patients with back abscess were included. The average size of their abscess was(150.3±101.2)cm 2, with over 100 cm 2 in 8 cases(66.7%). Among the 12 patients, 11 patients underwent bacterial culture and drug sensitivity analysis. The positive rate of culture was 100%, and all of them were Staphylococcus aureus, with 10 cases of methicillin-susceptible Staphylococcus aureus(MSSA)and 1 case of methicillin-resistant Staphylococcus aureus(MRSA). MSSA strains were 100% sensitive to oxacillin, vancomycin, linezolid, levofloxacin, moxifloxacin, tetracycline, tegecycline, rifampicin, amoxicillin/clavulanic acid, amikacin, and teicoplanin. Both MSSA and MRSA strains were sensitive to vancomycin, linezolid, rifampin, amikacin, and teicoplanin. The wound of all patients was healed, with 100% cure rate and(35.8±34.0)days of average healing time. Conclusion:The back abscess in type 2 diabetic patients is characteristic of rapid progress, huge abscess, and difficult to treat, which should be treated early, incised and debrided timely. Staphylococcus aureus is its single pathogen and it is helpful to select the antibiotics empirically.

Mutation analysis of thyroid peroxidase gene in a Chinese family with congenital hypothyroidism and literature review / 中华内分泌代谢杂志

In this paper, thyroid peroxidase (TPO) gene mutation was studied in a congenital hypothyroidism (CH) family with 2 patients, to explore the mechanism of c. 2268dupT homozygous mutation leading to thyroid nodules, as well as the relationship between TPO gene mutation and thyroid cancer. The result suggested that TPO gene mutation is one of the reasons for congenital hypothyroidism, TPO gene c. 2268 dupT mutations can lead to thyroid nodules, which may be related to long-term high TSH stimulation and truncated protein accumulation. TPO gene mutations have a certain correlation with thyroid cancer, the risk may increase with the increase of age, but the mechanism is not clear at present. In the future, further research on the correlation and mechanism between the two factors is needed, as well as to determine whether it is necessary to remove the thyroid gland to prevent the accarance of cancer in CH patients with TPO gene mutation with thyroid nodules.

Distribution characteristics of pathogen and antibiotic susceptibility in diabetic foot osteomyelitis / 中华内分泌代谢杂志

Objective:To retrospectively analyze distribution characteristics of pathogenic bacteria and their antimicrobial susceptibility in patients with diabetic foot osteomyelitis(DFO).Methods:Sixty cases of suspected DFO were collected from the Endocrinology Department of Henan Provincial People′s Hospital. After admission, bone biopsy was carried out to confirm the pathological diagnosis, and the pathogenic bacteria and drug sensitivity were determined by bone culture. In addition, bacterial culture was carried out in the basal tissue of the wound, and the results of bacterial culture were compared with those of bone culture.Results:Sixty patients were diagnosed as DFO after bone biopsy. Among the 60 patients, 45 patients underwent bone culture and basal tissue culture. There are 24 patients of whom the results were consistent, accounting for 53.3%. The positive rate of bone culture was 55.0%, there were 16 strains of gram-positive bacteria and 22 strains of gram-negative bacteria. Staphylococcus aureus(9 strains) occurrence was the most, common finding, followed by Escherichia coli(6 strains). The course of diabetic foot, albumin(ALB), and antibiotic usage rate before admission were lower in bone culture positive group than those in bone culture negative group, while white blood cell(WBC) and C-reactive protein(CRP) were higher in bone culture negative group( P<0.05). There was no significant difference in gender, age, course of diabetes, HbA 1C, and creatinine(CREA) levels between the two groups( P>0.05). The results of bone culture showed that Staphylococcus aureus was the main Gram-positive bacteria, which was more sensitive to vancomycin, tigecyclin, linezolid, etc. Escherichia coli was the main Gram-negative bacteria, which was more sensitive to tigecyclin, carbapenems, amikacin, etc. Conclusion:Bone biopsy and bone culture should be carried out in cases for suspected DFO patients to identify the pathogenic bacteria, and the bone tissue should be preserved and obtained according to the operation specification before the application of antibiotics, and the appropriate antibiotics should be selected according to the drug sensitivity results.

Early assessment value of brain function prognosis in patients with traumatic brain injury by regional saturation of cerebral oxygenation combined with percentage of α variability / 中华危重病急救医学

To explore the usability of regional saturation of cerebral oxygenation (rScO2) combined with percentage of α variability (PAV) in predicting brain function prognosis in patients with traumatic brain injury (TBI). Methods A retrospective analysis was conducted. The clinical data of patients with TBI who were monitored rScO2 and bedside quantitative electroencephalogram (qEEG) admitted to intensive care unit (ICU) of Henan Provincial People's Hospital from August 2018 to July 2019 were collected. The rScO2, PAV, and Glasgow coma scale (GCS) score were recorded within 72 hours after the TBI. The primary prognostic indicator was the 3-month Glasgow outcome score (GOS) score. The differences between the two groups of poor prognosis of brain function (GOS score 1-3) and good prognosis (GOS score 4-5) were compared. Binary multivariate Logistic regression analysis was used to analyze the correlation between rScO2, PAV, GCS score and the prognosis of brain function in patients with TBI. In addition, receiver operating characteristic (ROC) curve was plotted to analyze the predicting value of rScO2 and PAV only or combination for prognosis of brain function. Results A total of 42 patients with TBI were enrolled in the study, with rScO2≥0.60 (grade Ⅰ) in 14 patients, 0.50≤rScO2 < 0.60 (grade Ⅱ) in 16 patients,and rScO2 < 0.50 (grade Ⅲ) in 12 patients. PAV 3-4 scores (grade Ⅰ) were detected in 16 patients, 2 scores (grade Ⅱ) in 17 patients, and 1 score (grade Ⅲ) in 9 patients. GCS score 9-14 (grade Ⅰ) were observed in 13 patients,4-8 (grade Ⅱ) in 23 patients, and 3 (grade Ⅲ) in 6 patients; 18 patients had poor prognosis and 24 had good one. The rScO2, PAV and GCS scores of the poor-prognosis group were significantly higher than those in the good-prognosis group [rScO2 with grade Ⅲ: 55.6% (10/18) vs. 8.3% (2/24), PAV with grade Ⅲ: 38.9% (7/18) vs. 8.4% (2/24), GCS score with grade Ⅲ: 27.7% (5/18) vs. 4.1% (1/24)] with significant differences (all P < 0.05). There was no significant difference in other general data including gender, age, total length of hospital stay or acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score between the two groups. Binary multivariate Logistic regression analysis showed that rScO2 and PAV were independent risk factors for prognosis of brain in patients with TBI [rScO2: odds ratio (OR) = 4.656, 95% confidence interval (95%CI) was 1.071-20.233, P = 0.040; PAV: OR = 3.525, 95%CI was 1.044-11.906, P = 0.042]. ROC curve analysis showed that both of rScO2 and PAV had predictive value for the prognosis of brain function in patients with TBI (AUC was 0.796 and 0.780, respectively, both P < 0.01), and rScO2 combined with PAV had higher predictive value with the AUC of 0.851 (P < 0.01) than rScO2 or PAV alone, the sensitivity was 94.4% and the specificity was 62.5%. Conclusions rScO2 and PAV were associated with early brain function prognosis in patients with TBI. The combination of two monitoring indicators can reliably assess the prognosis of brain function in patients with TBI.

OBJECTIVE@#To explore the genotype-phenotype correlation among 18 patients with 21-hydroxylase deficiency (21-OHD).@*METHODS@#PCR-Sanger sequencing was used to analyze the 10 exons and flanking regions of the CYP21A2 gene among the 18 patients and 20 healthy controls.@*RESULTS@#Seventeen patients had variants of the CYP21A2 gene. Eight patients (44.4%, 8/18) carried homozygous variants including p.Ile 173Asn (62.5%, 5/8), p.Pro31Leu (25.0%, 2/8), and IVS2-13A/C>G (12.5%, 1/8), respectively. Six patients (33.3%, 6/18) carried compound heterozygous variant, among which IVS2-13 A>G+p.Ile 173Asn were most common (50.0%). 94.4% (34/36) of the variant were pathogenic, with the most common variants being p.Ile173Asn (41.7%), IVS2-13A/C>G (19.4%), and p.Ile173Asn (7.5%). No variant was identified among the 20 healthy controls.@*CONCLUSION@#The majority of 21-OHD patients carried CYP21A2 gene variants in homozygous or compound heterozygous forms, among which the p.Ile173Asn was the most common one. There is a strong correlation between the genotypes and clinical phenotypes.

Clinical and mutational analysis of 7 children with X-linked adrenal dysplasia congenita / 中华医学遗传学杂志

OBJECTIVE@#To summarize clinical manifestations, inheritance pattern and mutations of NR0B1 gene in 7 children with X-linked adrenal dysplasia congenita (XL-AHC).@*METHODS@#Clinical data of the 7 children was collected. Next-generation sequencing was carried out to detect potential mutations in the coding regions of adrenal gland-related genes. Suspected mutations were verified with Sanger sequencing.@*RESULTS@#In all of the children, the initial symptom was adrenocortical insufficiency. Five cases had neonatal onset, while the remaining two developed it at the age of 2. Three cases (42.9%) had a short stature and 1 showed growth retardation (14.3%). Of the 7 cases, 6 (85.7%) had mutations occurring in exon 1, and 1 (14.3%) had it occurring in exon 2. Four cases (57.1%) were frameshift mutations, 2 cases (28.6%) were nonsense mutations and 1 case (14.3%) was missense mutation. Two mutations were known to be pathogenic, and 5 had not been reported previously. Maternal inheritance was found in 6 cases. Three children had a maternal uncle died of unexplained causes. The mothers of 2 children had a history of spontaneous abortions. One child had a brother died of unexplained reason.@*CONCLUSION@#Male children with primary adrenal insufficiency should be routinely checked for NR0B1 mutations, especially those with a family history. mutations of NR0B1 gene occur mostly in exon 1, with frameshift mutations being the most common type. The development of all patients with XL-AHC should be closely monitored during follow-up.

Objective To compare the results of GnRHa stimulation test and GnRH stimulation test in girls with Idiopathic central precocious puberty.Methods The girls aged 6-10 who were diagnosed with early breast development (＜ 8 years old) from January 2016 to June 2018 were randomly divided into GnRHa stimulation test group and GnRH stimulation test group according to clinical manifestations,auxiliary examinations and follow-up.The difference in the results of the stimulation test between the two groups was compared.Results A total of 108 girls were enrolled in this study,and 40 (37％) of the GnRHa stimulation tests were performed.Among them,25 (63％) patients with idiopathic central precocious puberty had the confirmed diagnosis,and the GnRH stimulation test was performed.Of the 68 (63％) patients,30 (44％) had idiopathic central precocious puberty.The peaks of LH in the GnRHa challenge test group and the GnRH challenge test groupwere 11.33 (6.81,15.79) and 7.89 (5.35,14.21),and the FSH peaks were 15.68 (10.18,20.06) and 17.26 (13.34,21.42),showing no significant differences (U =1078.50,P =0.07;U =1617.50,P=0.10).Thepeak values of LH/FSH were0.86 (0.37,1.17)and0.52 (0.31,0.83),respectively,and there was a statistical difference (U =953.00,P =0.01).GnRH challenge test showed the ICPP sensitivity of 90.91％ (81.10％-100.72％),specificity of 94.29％ (86.60％-101.98％),total coincidence rate of 92.65％ (86.44 ％-98.85％),Yoden index of 0.85 (0.72％-0.98％).Sensitivity of the GnRHa challenge test showed the ICPP diagnosis rate of 95.24％ (86.13％-104.35％),specificity of 73.68％ (53.88％-93.48％),total coincidence rate of 85.00％ (73.93％-96.07％),Yoden index of 0.69 (0.47-0.91).Conclusion For the diagnosis of idiopathic central precocious puberty in girls,the GnRHa challenge test is more sensitive than the GnRH challenge test,and the specificity and the Yoden index are both low.Therefore,routine use of GnRHa stimulation test as the replacement of GnRH stimulation test is not recommended.

Clinical features and genetic analysis of seven patients with congenital hyperinsulinism / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To analyze clinical characteristics, genetic mutation and therapeutic effect of seven patients diagnosed with congenital hyperinsulinism(CHI).</p><p><b>METHODS</b>Clinical data for the patients was retrospectively analyzed.</p><p><b>RESULTS</b>All patients presented with hyperinsulinism(serum insulin:2.0-58.4 mU/L),even after hypoglycemia (blood glucose: 0.7-2.39 mmol/L) has developed. Mutations were identified in 4 patients (57.1%), which included a heterozygous c.262C to T(p.R88C) mutation in exon 4 of the UCP2 gene, a heterozygous c.1495C to A(p.G499C) mutation in exon 12 of the GLUD1 gene, a heterozygous c.1493C to T(p.S498L) mutation in exon 1 of the GLUD1 gene, and a heterozygous c.4432G to A(p.G1478R) mutation in exon 37 of the ABCC8 gene. The patient carrying a maternally inherited ABCC8 mutation was treated with cornstarch and had his blood glucose kept normal. All other patients responded well to diazoxide.</p><p><b>CONCLUSION</b>A genetic diagnosis was attained for 51.7% of patients in this study. Mild CHI patients can have their blood glucose controlled by giving cornstarch. Diazoxide is safe and effective for most CHI patients.</p>

Anomalous left coronary artery originating from the pulmonary artery postoperative follow-up and its prognosis / 中华胸心血管外科杂志

Objective To evaluate it' s prognosis according to the follow-up statistics of coronary reimplantation of anomalous left coronary artery originating from the pulmonary artery (ALCAPA).Methods Analyze the preoperative,peri-operative and postoperative data of 20 ALCAPA patients having undergone coronary artery reimplantation.Results After coronary reimplantation,patient' s cardiothoracic ratio was obviously decreased,the degree of myocardial ischemia was improved according to electrocardiogram,the left ventricular ejection fraction and fractional shortening showed a trend of rise,mostof the patients recover in 6 months to 1 year after coronary artery reimplantation.Left ventricular end-diastolic volume index over time gradually returned to normal,mitral regurgitation gradually.improved.Conclusion ALCAPA is rare and fatal,therefore it should be diagnosed and treated as early as possible.It is also significant to avoid missed diagnosis and misdiagnosis.After coronary reimplantation,cardiac function can be gradually restored with low mortality and good prognosis result.The left ventricularejection fraction of most patients recovers to the normal standard in six months to one year' s time.
