Objective To investigate the changes of excitatory amino acids (EAAs) of cerebrospinalfluid (CSF) in patients with delayed encephalopathy after acute carbon monoxide poisoning(DEACMP).Method The EAAs levels of CSF including glutamate (Glu) and aspartate (Asp) in 24 patients with DEACMP and 20 controls with migraine were measured by high performance liquid chromatography( HPLC ).Results Glu and Asp levels in patients with DEACMP were significantly higher than those of the controls [(3.76 ± 1.52) μmol/L vs ( 1.55 ± 1.03 ) μmol/L, (0.73 ± 0.44) μmol/L vs (0.38 ± 0.33 ) μmol/L, P all <0.01]. Glu and Asp levels in moderate and severe DEACMP patients were higher than those in mild DEACMP patients. Conclusion It suggests that EAAs participated in the pathogenesis of DEACMP. The Glu and Asp levels in CSF may be regarded as indicator of DEACMP.

AIM　To investigate the transdermal delivery effects of cyclosporine A solubilized in mixed micelles composed of phospholipid and different surfactants. METHODS　When applied onto the excised abdominal skin of the mice occlusively, the enhancing effects of various mixed micelles on the penetration of cyclosporin A were assessed by an in vitro permeation technique. In vivo study was carried out by topical application of sodium cholate-phospholipid mixed micelles onto the mice skin and drug blood concentration was detected. RESULTS　In vitro, mixed micelles containing different surfactants displayed distinct permeability and corresponded to the following order: sodium cholate > sodium deoxycholate > Trition X-100 > Tween-20. In vivo, peak drug concentration was detected at 5 h and after that the concentration fell down slowly. CONCLUSION　Mixed micelles were shown to be efficient carrier for the transdermal delivery of the lipophilic polypeptide when kept in solution during the application process.

For effective inhalable dry-powder drug delivery, tetrandrine-PLGA (polylactic-co-glycolic acid) nanocomposite particles have been developed to overcome the disadvantages of nanoparticles and microparticles. The primary nanoparticles were prepared by using premix membrane emulsification method. To prepare second particles, they were spray dried. The final particles were characterized by scanning electron microscopy (SEM), dry laser particle size analysis, high performance liquid chromatography (HPLC), X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared analysis (IR) and confocal laser scanning microscope (CLSM). The average size of the primary particles was (337.5 ± 6.2) nm, while that second particles was (3.675 ± 0.16) μm which can be decomposed into primary nanoparticles in water. And the second particles were solid sphere-like with the drug dispersed as armorphous form in them. It is a reference for components delivery to lung in a new form.

Objective:To investigate the surgical method and therapeutic effect on repairing soft tissue defects around ankle with lateral tarsal artery island flap.Methods:From July 2013 to December 2020, the lateral tarsal artery island flap were used to repair the soft tissue defects around ankle in 12 patients in Hand Surgery Department, Jiangnan Hospital Affiliated to Binjiang College. Of which, 6 patients had soft tissue defects complicated with bone or tendon exposure after injury and 6 had skin necrosis with internal fixation after fracture. The area of soft tissue defects was 6.0 cm×4.0 cm-9.0 cm×5.0 cm, and the size of the flaps was 7.0 cm×5.0 cm-10.0 cm×6.0 cm. After the flap was freed, the vascular pedicle was separated up to the origin of dorsalis pedis artery. As the pedicel was not long enough in 1 patient, the dorsal pedis artery was ligated and transected at the origin of the lateral tarsal artery. Full thickness skin graft was used to repair the donor sites. The patients were treated with anti-infection and anticoagulant therapies. The postoperative follow-ups were conducted by outpatient clinic visit, telephone or WeChat interviews or home visit to observe the recoveries in texture, appearance, sensation, donor site and function of ankle.Results:All the flaps and skin grafts survived. The wound healed well without occurrence of ulcer. The follow-up ranged 6-108 months (mean 17 months). Appearance of the flaps was good. It was not bloated and the sensation was restored to S 2-S 3. Conclusion:It is a good method to apply the lateral tarsal artery island flap in repair of the soft tissue defects around ankle. It features a hidden donor site, simple operation and the high level of safety. The texture and appearance of the flap are close to those of the recipient site.

Objective: To explore the mediating, direct and indirect roles of self-efficacy, social support and medical coping modes with resilience in patients with chronic hepatitis B. Methods: Totally 384 inpatients and outpatients with chronic hepatitis B, without physical ailments or mental problems were selected.The Connor-Davidson resilience scale (CD-RISC), general self-efficacy scale (GSES), medical coping modes questionnaire (MCMQ) and social support rating scale (SSRS) were adopted in this research.The relationship among all variables was explored by path analysis. Results: (1)The total scores of resilience, self-efficacy, social support, confrontation, avoidance and acceptance-resignation in chronic hepatitis B patients were (61.64±15.36), (25.40±5.70), (39.82±7.39), (19.02±3.72), (16.63±2.69) and (8.45±2.94), respectively.(2)Pearson analysis showed that the scores of self-efficacy, medical coping and social support were significantly correlated with resilience(r=-0.26-0.82, P<0.05). (3)Importantly, path analysis showed that self-efficacy(β=0.53), confrontation(β=0.10), avoidance(β=0.17) and acceptance-resignation(β=-0.13) had direct prediction effects on resilience.Additionally, self-efficacy was indirectly related to resilience(β=0.05), and social support also indirectly related to resilience through self-efficacy, confrontation and acceptance-resignation(β=0.18). Conclusion Self-efficacy, social support and medical coping are the important factors which play a direct or indirect role in resilience.

OBJECTIVE: To establish an interference mode of group counseling for diabetic patients with depression and to evaluate the effectiveness of this mode on depression, treatment compliance and blood sugar level in the patients.
 METHODS: One hundred diabetic patients with depression were randomly divided into a counseling group and a control group (n=50 per group). Self-Rating Depression Scale (SDS) was applied to all the patients. The interference mode of group counseling was established through literature review, expert consultation or interview. The counseling group received counseling for 8 times within 2 months.
 RESULTS: There was a significant difference in the SDS scores at 0, 3, 6 or 12 months after the intervention between the 2 groups (P<0.001). For the counseling group, there was a significant difference in the SDS scores between pre-intervention and 3, 6 or 12 months after intervention (P<0.001). However, there was no significant difference in the SDS scores between any two time points after the intervention (P>0.05). There was a significant difference in the compliance between any two time points after the intervention (P<0.05). Fasting blood glucose (FBG), 2 h postprandial blood glucose (2hPG) or glycosylated hemoglobin (HbA1c) was significantly different at any two time points after the intervention (P<0.05).
 CONCLUSION Group counseling can improve depression, compliance and blood sugar control in the diabetic patients.

OBJECTIVES: To describe the clinical characteristics and outcomes of severely ill patients with coronavirus disease 2019, and to investigate the relationship between plasma glucose level and the prognosis of severely ill patients with coronavirus disease 2019. METHODS: We enrolled 52 severely ill patients with coronavirus disease 2019. Among them, 12 cases progressed to critical illness. The clinical and biochemical characteristics of severely and critically ill patients were compared. RESULTS: Compared with the severely ill patients, critically ill patients had higher white blood cell and neutrophil counts, as well as higher levels of -dimer, IL-6 and C-reactive protein (all <0.05). Before treatment, the fasting plasma glucose (FPG) levels were significantly higher in the critically ill patient's group [(10.23±3.71) mmol/L] compared to those in the severely ill patients [(7.12±3.35) mmol/L, <0.05]. After adjusting for age, gender, and course of the disease, fasting blood glucose at admission (OR=1.308, 95% CI 1.066 to 1.606, =0.01) and hyperglycemia at admission (OR=29.198, 95% CI 2.903 to 293.639, =0.004) were closely related to whether severely ill patients progressed to critical patients with coronavirus disease 2019. In our study, 15 (34.8%) of the severely ill and 10 (83.3%) critically ill patients received the steroid treatment. Compared with the severely ill patients, the FPG levels in critically ill patients were higher (<0.05). CONCLUSIONS Fasting hyperglycemia at admission is a significant predictor for the prognosis of severely ill patients with coronavirus disease 2019. Closely monitoring and the optimal management of hyperglycemia may improve the prognosis of patients with coronavirus disease 2019.

ObjectiveTo study the potential quality marker （Q-marker） of Tinosporae Radix associated with efficacy of "relieving sore throat" based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS）， multivariate statistical analysis （MSA）， and network pharmacology. MethodUPLC-Q-TOF-MS was used to identify the main chemical components in 18 batches of Tinosporae Radix. On this basis， principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） were employed to screen out the main marker components that caused differences between groups. Moreover， network pharmacology technology was applied to predict the potential "sore throat-relieving" components， and the molecular docking between the common components resulting from MSA and network pharmacology and the core targets was carried out to verify the marker components. ResultA total of 17 compounds， including alkaloids， diterpenoid lactones， and sterols， were identified by UPLC-Q-TOF-MS. Five main differential components were found by MSA： Columbamine， jatrorrhizine， palmatine， menisperine， and columbin. Network pharmacology analysis yielded six compounds： tetrahydropalmatine， palmatine， menisperine， fibleucin， neoechinulin A， and columbin which were selected as potential "sore throat-relieving" components of Tinosporae Radix. They may relieve sore throat by acting on interleukin-6， epidermal growth factor receptor， prostaglandin G/H synthase 2， matrix metalloproteinase-9， proto-oncogene tyrosine-protein kinase Src and other targets， and regulating Hepatitis B， influenza A， human T-cell virus infection， human cytomegalovirus infection， coronavirus disease-2019， and other signaling pathways. The common active components in Tinosporae Radix resulting from MSA and network pharmacology analysis were palmatine， menisperine， and columbin， which had high binding affinity with six core targets and can be used as the Q-marker components of Tinosporae Radix in "relieving sore throat". ConclusionThis study predicts the "sore throat-relieving" Q-marker of Tinosporae Radix， which lays a basis for developing the quality standard of Tinosporae Radix based on the efficacy and improving the quality evaluation system of the medicinal.
