AlM: To explore the clinical application effect of phacofragmentation combined with vitrectomy in the treatment of traumatic lens dislocation.
METHODS:Totally 16 cases (16 eyes) of traumatic lens dislocation treated with phacofragmentation combined with vitrectomy were retrospectively analyzed, including 6 cases of high intraocular pressure ( lOP) and 10 cases of vitreous hemorrhage, and 1 case of retinal detachment. All patients were given conventional flat line standard three channel vitreous operation incision to remove the anterior, middle part and peripheral vitreous around lens dislocation. The crystalline lens were drawn to the center cavity of vitreous body and treated by ultrasonic disintegrator. ln the operation, the retina was examined and 8 of them had no retinal damage and in the first stage underwent fixation of posterior chamber intraocular lenses.
RESULTS: All crystalline lens dislocated were completely grinded and suctioned. There was no retinal detachment occurred in 3mo followed up. 16 eyes had normal lOP (12-20mmHg) at 1wk after operation. The average visual acuity was improved and with 8 cases got improved of 0. 2 or more 1wk after operation.
CONCLUSlON: Our research shows that phacofragmentation combined with vitrectomy is a safe and effective method for the treatment of traumatic lens dislocation. The patients with nondestructive retina in the operation are feasible to do first stage operation of intraocular lens suture fixation, which contributes to the best visual acuity.

To study the mechanisms of total flavonoid from Glycyrrhizae Radix et Rhizoma (TFGR) and its ingredient isoliquiritigenin (ISL) on their regulation of M2 phenotype polarization of macrophages. IL-4 (60 μg x L(-1)) induced RAW264.7 cells for 6 h to establish the M2 macrophage model. TFGR and ISL restrained breast cancer cells migration with the aid of M2 macrophages in vitro. TFGR and ISL inhibited gene and protein expression of Arg-1, up-regulated gene of HO-1 and protein expression of iNOS, enhanced the expression of microRNA 155 and its target gene SHIP1, meanwhile down-regulated.the phosphorylation of STAT3 and STAT6. So TFGR and ISL were the bioactive fraction and ingredient in Glycyrrhizae Radix et Rhizoma to reverse M2 phenotype macrophages polarization. TFGR and ISL inhibited the promotion of M2 macrophages to breast cancer cells migration in vitro, STAT signal pathways and miR155 were partly involved.

Objective:
To learn the concentration of target genes of severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2 ) and the influencing factors in the confirmed cases with coronavirus disease 2019 ( COVID-19 ) in Ningbo.
Methods:
Demographic information and clinical diagnosis of COVID-19 cases reported in Ningbo from January 21 to February 20, 2020 were collected through China Disease Control and Prevention Information System. The Ct values of ORF1ab and N of the cases were collected through Ningbo Center for Disease Control and Prevention and designated hospitals, and analyzed in terms of gender, age, severity, clinical classification, source of case, sampling time and specimen type.
Results:
There were 157 confirmed COVID-19 cases, including 56 males ( 35.67% ) and 101 females ( 64.33% ). Sixty-seven cases ( 42.68% ) aged between 40 and 60 years old. The Ct values of ORF1ab and N in females were 29.96±5.28 and 30.38±4.90, which were higher than 27.56±4.94 and 28.03±4.88 in males ( P<0.05 ). The Ct values of ORF1ab and N were the lowest when sampled at 1-7 days after onset ( P<0.05 ), which were 27.84±4.80 and 28.35±4.65. The Ct values of ORF1ab ( rs=0.288, P=0.001 ) and N ( rs=0.296, P=0.001 ) were positively correlated with sampling time. The Ct values of ORF1ab in pharyngeal swab and sputum were 29.19±4.85 and 28.74±6.40, the Ct values of N in pharyngeal swab and sputum were 29.61±4.60 and 29.22±6.10, both without significant differences between different samples ( P>0.05 ).
Conclusions
Sampling time has a great influence on the Ct values of ORF1ab and N of SARS-CoV-2.

AIM: To retrospectively evaluate the effect of lens extraction combined with vitrectomy to treat traumatic lens dislocation with secondary glaucoma.
METHODS: Thirty - one eyes ( 31 cases ) of lens dislocation caused by blunt trauma with secondary glaucoma were treated respectively with cataract extraction combined with anterior vitrectomy, trabeculectomy and intraocular lens implantation. The visual acuity and pressure were observed 1wk, 1 and 3mo after operative.
RESULTS: Thirty - one eyes were all complete the operation successfully, and 6 eyes were given combined trabeculectomy, 9 eyes were implanted anterior chamber intraocular lens implantation ( IOL ) and 15 eyes were given posterior chamber suture fixation. Sixteen eyes were implanted in one-stage operation, while 8 eyes were implanted in two-stage operation. All intraocular pressure ( IOP ) were controlled to the normal level after operation and 23 eyes had visual acuity of more than 0. 3. CONCLUSION: Lens extraction combined with vitrectomy is an effective method for treatment of lens dislocation with secondary glaucoma. In order to control the IOP and get well visual function, we should choose IOL implantation or trabeculectomy according to the patient's condition.

OBJECTIVE:To investigate the occurrence of ADR induced by Shuxuening injection in Beijing area,and to pro-vide reference for rational drug use in clinic. METHODS:ADR induced by Shuxuening injection in Beijing area during 2003-2013 was classified statistically in respects of population,organs/systems involved in ADR,clinical manifestations,occurrence time, drug combination and prognosis. RESULTS:Of 1648 ADR cases,the incidence of ADR in the elderly patients was higher than young patients,and that of female patients (60.92%) was higher than that of male patients (39.14%). Multiple organs/systems were involved in Shuxuening injection-induced ADR,and top 3 were nervous system (422 cases,21.33%),skin and its appen-dants (411 cases,20.78%) and others (305 cases,15.42%). Clinical manifestations were skin rash,itching,dizziness and ner-vousness,palpitation,arrhythmia,etc. ADR mostly occurred within 5-30 min after medication. In ADR reports,there were a vari-ety of drugs combined with Shuxuening injection. Shuxuening injection combined with Alprostadil injection was most common(61 cases,accounting for 23.46% of drug combination). Among 1648 ADR cases,there were 622 cured cases and 1039 cases im-proved,4 cases were not improved,3 cases had sequelae and 1 case died. CONCLUSIONS:Clinical application of Shuxuening in-jection should strictly follow the indications of drug package inserts;differentiation of symptoms and signs is based on specific dos-age,solvent,route of administration,etc. It is necessary to strengthen the prescription check,and strengthen the observation after medication especially for the elderly and other special groups so as to reduce and avoid ADR.
