AIM: To investigate the clinical efficacy of femtosecond laser-assisted phacoemulsification combined with goniosynechialysis in the treatment of acute angle-closure glaucoma complicated with cataract.METHODS: A total of 53 patients(60 eyes)with primary acute angle closure glaucoma complicated with cataract admitted to our hospital from April 2020 to February 2021 were selected. They were divided into two groups according to the surgical method, with 28 cases(30 eyes)who were treated with femtosecond laser-assisted phacoemulsification combined with goniosynechialysis in group A, and 25 cases(30 eyes)who were treated with traditional cataract phacoemulsification combined with goniosynechialysis in group B. The effective phacoemulsification time(EPT)and cumulative dissipated energy(CDE)during surgery in two groups were recorded. Patients were followed up to 3mo after surgery, and the intraocular pressure, anterior chamber depth(ACD), best corrected visual acuity, corneal endothelial cell loss rate(ECL)and surgical complications were observed in both groups.RESULTS: The postoperative intraocular pressure was significantly decreased and ACD was significantly increased(all P<0.05), and there was no difference between the two groups(all P>0.05). The postoperative best corrected visual acuity of the two groups was significantly better than that before surgery(P<0.05), and group A was significantly better than group B at 1d after surgery(P<0.05). The EPT, CDE, ECL and incidence of complications(7% vs. 27%)in group A were significantly lower than those in group B(all P<0.05).CONCLUSION: Femtosecond laser-assisted cataract phacoemulsification combined with goniosynechialysis in the treatment of primary acute angle-closure glaucoma combined with cataract has a significant therapeutic effect, which can effectively improve surgical safety, reduce the rate of corneal endothelial cell loss, and have fewer complications.

Objective:To identify the quality differential markers of different processed products of Glycyrrhiza uralensis dry roots and rhizomes. Method:Ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MSE) was used to collect high-precision mass-charge ratio and ion response strength information of the components in G. uralensis dry roots and rhizomes before and after processing by negative ion mode. The data set collected after pretreatment was analyzed with principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) to quickly search the differential components in different processed products of G. uralensis dry roots and rhizomes. Differential components were identified according to the relative molecular weight, fragment ion, mass spectrum database and related literature information, then the migration of components before and after processing was studied. Result:A total of 10 quality differential markers were searched from raw products, roasted products and honey-roasted products of G. uralensis dry roots and rhizomes, mainly derivatives of liquiritin and glycyrrhizic acid. Among them, the contents of 6''-O-acetylliquiritin apioside, 6''-O-acetylliquiritin apioside isomer, 6''-O-acetylliquiritin, formononetin and 11-deoxo-18β-glycyrrhetic acid were the highest in the raw products, the contents of 6''-O-acetylisoliquiritin apioside, 6''-O-acetylisoliquiritin, isoliquiritin and glycyrrhetic acid 3-O-glucuronide were the highest in the roasted products, the content of liquiritin was the lowest in the honey-roasted products. Conclusion:There are some chemical differences among the three products. This study can provide material basis for the quality control and pharmacodynamic research of processed products of G. uralensis dry roots and rhizomes.

Objective To analyze the resistance of influenza virus to neuraminidase inhibitors (NAI) in Henan province during 2017-2018. Methods Virus were collected from the Henan Influenza Surveillance Network during 2017-2018. 36 confirmed influenza virus(with 15 H1pdm09,6 H3N2 and 15 B) were selected to test resistance to oseltamivir and zanamivi with fluorescence(FL). The NAI sensitive reference viruses were A/California/12/2012(H1pdm09)-275H,A/Beijing Haidian/1942/2014(H3N2)-119E and B/Rochester/02/2001-198D. The NAI resistant reference viruses were A/ Texas/23/2012(H1pdm9)-H275Y, A/Texas/12/2007(H3N2)-E119V and B/Rochester/02/2001-D198N. Results The half maximal inhibitory concentration(IC50) of A/California/12/2012(H1pdm09)-275H, A/Beijing-Haidian/1942/2014(H3N2)-119E and B/Rochester/02/2001-198D for oseltamivir were 0.29 nmol/L (nM),0.10 nM and 12.71 nM, and for zanamivir were 0.2 nM, 0.49 nM and 0.33 nM respectively. The IC50 for oxastatin of H1pdm09 and H3N2 ranged from (0.28-1.37 nM) and (0.08-0.17 nM) respectively, the IC50 for zanamivir ranged from (0.15-0.49 nM) and (0.12-0.22 nM), all was within 10 fold IC50 of the reference virus(corresponding type); the IC50 value of type B for oseltamivir and zanamivir ranged from (11.83-24.59 nM) and (0.48-1.25 nM), all was within 5 fold IC50 of the reference virus. Conclusion All the tested influenza strains isolated in Henan province during 2017-2018 were sensitive to NAI.

Objective To analyze the characteristics of adverse reactions for varicella attenuated live vaccine (VarV) in Henan Province from 2011 to 2016, in order to evaluate the immunization safety related to VarV. Methods The adverse reaction data and vaccination doses of VarV in Henan Province from 2011 to 2016 were collected through the China Information Management System for Immunization Programming. The descriptive methodology was used for data analysis. Results A total of 686 adverse reactions cases were reported in Henan Province from 2011 to 2016, and the average reported incidence rate was 16.89 per 100000 dose. The ratio of male to female was 1.14:1, and 80.61% cases occurred between 1 and 2 years old, and the reported incidence rate was 13.62 per 100000 dose. And 32.80% cases were reported from April to June, and the reported incidence rate was 5.54 per 100000 dose. The cases were mainly concentrated in Zhengzhou, Luoyang, Zhoukou and Xinyang. Most cases occurred after the first dose and within 1 d after vaccination. The main diagnoses of adverse reactions were fever, local swelling, indurations and transient anaphylactic disorders. The reported incidence rate of anaphylactic shock and fever convulsion were 0.37 per 100000 dose and 0.12 per 100000 dose respectively. All cases were recovered or got better. Conclusion The safety of VarV was good in Henan Province. However, the surveillance should focus on the anaphylactic shock and fever convulsion and other serious rare adverse reaction.

Liver failure is the end stage of hepatopathy with unfavorable prognosis. In two patients with liver failure, viable primary human hepatocytes, obtained from resected liver tissue of patients with hepatolithiasis, were transplanted into the spleen by interventional therapy through femoral arterial cannula. After transplantation, the patients' clinical symptoms and liver function were significantly improved. However, their bilirubin increased within six days following transplantation. One suffered from hepatic coma and give up treatment and the other patient died fourteen days after transplantation. It is technically safe to treat liver failure by intrasplenic transplantation of adult hepatocytes and the clinical efficacy has been confirmed. How to make transplanted hepatic cells proliferate and functionally survive is the key point to maintain continuous improvement of the recipient's hepatic function.
