Objective To summarize nursing methods of patients with choked disc correlated to cerebral venous sinus thrombosis undergoing optic nerve sheath fenestration.Methods The effects of optic nerve sheath fenestration was observed by preoperative and postoperative tracking of vision changes in 41 eyes of 30 patients for 12 months.Results After the operation and the corresponding nursing, the preoperative and postoperative vision of 41 eyes was statistically significant (P<0.01). Among the 41 eyes, 21.9% improved vision, 60.9% stable,and only 4.9% deteriorated;12.3% with no light feeling before operation failed to improve vision.Conclusions Optic nerve sheath fenestration can effectively protect the vision of choked disc correlated to cerebral venous sinus thrombosis. Better nursing is needed including high intracranial pressure, bleeding potential, specific care, psychological need, complications prevention and health education, to improve clinical symptoms and ensure well processing of operations.

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a common complication after liver transplantation, which could prolong the length of postoperative intensive care unit stay, affect clinical efficacy of liver transplantation and even lead to the death of recipients. ALI/ARDS has attracted extensive attention from liver transplant surgeons in clinical practice. ALI/ARDS after liver transplantation may be directly caused by pulmonary factors (such as mechanical ventilation-related lung injury, lung infection and aspiration, etc.) or indirectly induced by non-pulmonary factors (such as severe infection outside the lungs, blood transfusion and ischemia-reperfusion injury, etc.). In this article, the diagnostic criteria, incidence, mechanism, risk factors, laboratory and clinical diagnostic approaches and treatment of ALI/ARDS after liver transplantation were reviewed, aiming to deepen the understanding and cognition of ALI/ARDS during the perioperative period of liver transplantation and provide reference for the diagnosis and treatment of ALI/ARDS following liver transplantation.

Objective To explore the effect of psychotherapy in patients with optic papilledema undergoing optic nerve sheath fenestration (ONSF).Methods Using convenience sampling method,a total of 64 patients with intracranial hypertension and optic papillary edema who were diagnosed by Ophthalmology Department of Xuanwu Hospital of Capital Medical University from 2013 to 2017 were selected as the subjects of study.All the subjects were randomly divided into two groups,with 32 patients in each group.Patients in the control group received routine ophthalmic nursing.The patients in the observation group were given six-step psychological intervention.Self-rating Anxiety Scale (SAS) were applied within 2 days after admission and before discharge to evaluate the patients.Results The score of SAS before discharge in the observation group was (46.28±4.48),which was lower than that in the control group (56.84±8.25),and the difference was statistically significant (t=6.363,P＜0.01).Conclusions Relevant psychotherapy can improve the anxiety of patients,so that patients can cooperate well with the treatment,which is worthy of clinical application.

Lung toxin refers to the external or internal toxic substances accumulated in the lung, resulting in physiological disorder of Zang-fu organs, and abnormal circulation of qi, blood, and body fluids.Lung toxin mainly includes phlegm and stasis toxin, obstructs lung collaterals and leads to the occult development of idiopathic pulmonary fibrosis, which falls into the category of lung bi-syndrome in Traditional chinese medicine.This disease tends to linger, damage healthy qi, affect physique, and often presents with unfavorable prognosis.

Objective:To confirm the first imported Chikungunya fever (CHIK) epidemic in Hunan province.Methods:Serum samples of patients and colleagues were collected. The nucleic acids of Dengue virus (DENV), Yellow fever virus (YFV), Chikungunya virus (CHIKV) were detected by real- time fluorescent quantitative PCR. The positive PCR products were sequenced. Phylogenetic tree was constructed.Results:The serum samples of the patient and one of the five colleagues were positive for CHIKV. The Blast comparison of gene sequence showed 99% homology with CHIKV sequences. The infected CHIKV belonged to ECSA genotype in the phylogenetic tree.Conclusions:The first imported CHIK epidemic in Hunan province was confirmed through the epidemiological survey and etiologic detection.

Objective To analyze the correlation between detection of influenza pathogenic subtypes and epidemic situation in Hefei City during the surveillance years of 2015-2021, and to provide references for developing influenza prevention and control strategies. Methods The relevant data of influenza-like illness (ILI) surveillance, influenza etiology, and outbreak/cluster outbreaks reported from influenza surveillance sentinel hospitals in Hefei City from 2015 to 2021 in the China Influenza Surveillance Information System were analyzed. The statistical analysis was carried out. Results A total of 3 332 553 outpatient and emergency visits in 2 sentinel hospitals were reported in Hefei City from 2015 to 2021, of which 139,082 were ILI cases, accounting for 4.17%. The monthly proportion ranged from 1.60% to 7.15%. A total of 14 663 ILI specimens were submitted for detection, the submission rate was 10.54%, and the positive rate of influenza virus detection was 11.30%. There was no correlation between the proportion of monthly influenza like cases and the detection rate (r_s=0.176, P=0.107). The composition ratio of each subtype of influenza virus varied greatly, showing diversified seasonality, and the epidemic strains changed constantly. The Victoria subtype (BV subtype) was dominant (40.21%). There was a moderate correlation between the positive rate of ILI in sentinel hospitals and the number of outbreaks per month (r_s=0.696, P=0.000). There was a strong correlation between the monthly number of outbreaks and the detection rate (r_ss=0.696, P=0.000). There was a strong correlation between influenza A virus H3 subtype and BV subtype (r_{s -H3}=0.686, P=0.030; r_{s -BV}=0.632, P=0.000). There was a moderate correlation between the new A1 subtype and B Yamagata subtype (r_{s -new A H1}=0.481, P=0.000 0; r_{s -BY}=0.515, P=0.000). Conclusion There are two epidemic peaks in spring and winter in Hefei. Influenza subtypes are diverse. The results of ILI etiology can predict the outbreaks of different subtypes of influenza. Prediction and surveillance should be used for influenza control and outbreak management in a timely manner.

OBJECTIVE To establish UHPLC-ELSD fingerprint and multi-component content determination methods, compare the differences in sheep bile from different regions, and conduct antioxidant activity research to provide a basis for the in-depth development and utilization of sheep bile. METHODS Used UHPLC-ELSD method to establish 21 batches of bile fingerprints of sheep from different origins and conduct similarity analysis. Measured the content of 6 components, DPPH and ABTS free radical scavenging ability, iron ion reduction ability, and conducted entropy weighted TOPSIS and grey correlation analysis. RESULTS A total of 11 common peaks were identified in the fingerprint spectra of 21 batches of sheep bile. Through comparison with the control sample, 6 components were identified, including taurocholic acid(TCA), glycocholic acid(GCA), taurochenodeoxycholic acid(TCDCA), tauroursodeoxycholic acid(TDCA), glycodeoxycholic acid(GDCA), and cholic acid(CA). Except for 4 batches of samples, the similarity of the fingerprint spectra was greater than 0.90. The total content range of 6 components in the freeze-dried powder of 21 batches of sheep bile was 55.34% to 86.08%. The highest content of taurocholic acid ranged from 34.74% to 60.86%, indicating significant differences in the content of the six components in samples from different regions. Sheep bile from different regions had antioxidant activity, and there were also certain differences. The results of entropy weighted TOPSIS analysis using six component contents as variables showed that the top ten scoring groups were S2, S18, S16, S9, S8, S21, S1, S10, S20, and S15, indicating good quality and slightly better bile quality from sheep in the northern region. The grey correlation analysis results between the content of 6 components and 3 antioxidant indicators showed that all 6 components were correlated with each antioxidant indicator, and TCA, TDCA, and TCDCA had the highest correlation, which might be important components for sheep bile to exert antioxidant effects. CONCLUSION The use of entropy weighted TOPSIS and grey correlation analysis methods can effectively analyze the quality differences and antioxidant active components of sheep bile from different regions, providing scientific basis for its quality evaluation.
