OBJECTIVETo investigate the relationship between two polymorphisms immediately upstream of the cyclooxygenase 2 (COX2) gene and preeclampsia in a South West Han Chinese population.

METHODSBlood samples from 205 patients with preeclampsia and 276 normal pregnant women as controls from Han Chinese in Chengdu area were analyzed by polymerase chain reaction-restriction fragment length polymorphisms.

RESULTSG and A allele frequencies for -1195G>A site were 48.54% and 51.46% in the patient group, respectively, and 40.40% and 59.60% in the control group, respectively. G and C allele frequencies for -765G>C site were 94.15% and 5.85% in the case group, respectively, and 94.38% and 5.62% in the control group, respectively. The AA genotype and variant A allelic frequencies of the -1195G>A SNP were significantly lower in patients with preeclampsia than in the control group (P<0.05), and the odds ratio for the risk of preeclampsia was 0.665 (95% CI: 0.444-0.982) in women homozygous for the variant COX2 A allele ( x²=4.233, P=0.047). The genotype and allele frequencies of the -765G>C polymorphism in patients with preeclampsia and controls showed no significant differences (P>0.05). Additional subgroup analyses (mild vs severe preeclampsia) of the two polymorphisms failed to reveal significant correlation for either genotypic or allelic frequencies. Furthermore, there was no significant association between the polymorphisms and blood pressure levels in the patient or control groups.

CONCLUSIONCOX2 -1195A homozygosity is associated with a decreased risk for preeclampsia in a South West Han Chinese population. On the other hand, the -765G>C polymorphism has no effect.

OBJECTIVETo study the effect and safety of Kudiezi injection on patients with acute ischemic stroke.

METHODSeven hundreds patients were divided into two groups by central randomization system. The study group, 346 cases, was treated with kudiezi injection plus traditional Chinese medicine (TCM) synthesis rehabilitation project, and the control group, 354 cases, was treated with synthetic rehabilitation project. The patients were treated for 10 to 21 days. Before treatment and at the 7th, 14th and 21th day of treatment, the indexes include NIHSS used for evaluating the neurological deficit degree and the motor function score (Fugl-Meyer) for evaluating motor function were observed. The safety index is defined by adverse observation event and laboratory test. The incidence of adverse events and laboratory tests results were observed before and after treatment at the same time.

RESULTApplication of generalized estimating equation model, we found that as the treatment time, NIHSS score and FMI score of the two groups showed a trend of improvement. And at the 14th days and 21th days of treatment, compared to the control group the treatment group showed significant statistical difference on the impact of NIHSS and FMI (P<0.05). No serious adverse events were observed.

CONCLUSIONKudiezi injection plus TCM rehabilitation project of ischemic stroke showed some superiority to western medicine rehabilitation program on improving the neurological deficit and motor function. Kudiezi injection is safe and effective in the treatment of acute ischemic stroke.

METHODA multicentre, prospective, practical, randomized controlled study was carried out to compare the efficacy and safety of Dengzhan group (n = 343) and western medicine group (n = 335), appling "clinical study central stochastic system". The treatment of Dengzhan group is using fleabane injection in acute stage and Dengzhan Shengmai capsules in convalescence. The primary indexes of effect evaluation are the important outcome events in 360 days' follow-up, including mortality, recurrence, disability and quality of life to reflect the effect of clinical study. The indexes of safety evaluation involve laboratory examination results and incidence of adverse events.

RESULTAfter 360 days' follow-up, 4 people died of IS in Dengzhan group, and the mortality rate of which is 1.17%, while 16 died in Western medicine group (WM group), and the mortality rate is 4.78%, suggesting that the mortality rate of Dengzhan group is significantly lower than WM group (P<0.05). Eleven cases recurred in Dengzhan group, and the recurrence rate of which is 3.21%, while 12 recurred in WM group, and the recurrence rate is 3.59%, indicating that the recurrence rate of Dengzhan group is slightly lower than WM group. The disability rate of Dengzhan group is 39.53%, among which the rate of severely disabled cases are 1.49%, while the disability rate of WM group is 40.13%, among which the rate of severely disabled cases are 3.13%, suggesting that the disability rate of Dengzhan group is lower and the severity of disability is also lighter than WM group. In the field of quality of life, the activity ability and the upper limb function store of stroke patients in Dengzhan group improved far much better than WM group (P<0.05). Analysis of safety suggested that, adverse events occurred in 11 cases in Dengzhan group, among which 4 cases is related with the drug treatment, the incidence of adverse events of which is 1.17%, and the main manifestations involve fever and chilling, rash, nausea, dizziness, palpitation, etc. which were all appeared after the treatment of fleabane injection, and disappeared 1 to 2 days after drug withdrawal. 13 cases occurred abnormal liver function and 2 cases abnormal kidney function in Dengzhan group. According to the judgment of clinical physicians, 3 case of ALT abnormality is possibly related to the treatment, the others are all unrelated with the treatment.

CONCLUSIONFleabane injection and Dengzhan Shengmai capsules are all safe and effective TCM in the treatment of ischemic stroke.

Objective:To compare ocular surface dry eye-related indexes and tear cytokine level changes in chronic ocular graft-versus-host disease (oGVHD) patients after receiving topical treatment of 0.05% cyclosporine or 0.1% tacrolimus eye drops.Methods:A randomized controlled study was conducted.A total of 60 chronic oGVHD patients (60 eyes) were recruited at Beijing University Third Hospital from April 2020 to April 2021.The patients were divided into tacrolimus group and cyclosporine group by a random number table, with 30 patients (30 eyes) in each group.Patients in tacrolimus group used 0.1% tacrolimus eye drops (twice a day) and patients in cyclosporine group used 0.05% cyclosporine eye drops (4 times a day).Additionally, 0.1% flumetholon (twice a day), deproteinized calf blood extract (3 times a day), and 0.1% sodium hyaluronate eye drops (8 times a day) were applied for anti-inflammation and lubrication in both groups.Patients were screened according to exclusion criteria after 1-month treatment.Eventually, 21 patients (21 eyes) in tacrolimus group and 12 patients (12 eyes) in cyclosporine group were included for further study.Patients were examined before and 1 month after treatment.The primary evaluation indexes included Ocular Surface Disease Index (OSDI), corneal fluorescein staining scores and tear film break-up time (BUT).Expressions of interleukin (IL)-6, IL-8, IL-17, epidermal growth factor (EGF), and tumor necrosis factor-α (TNF-α) in tears were detected before and after treatment using Luminex chip.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Peking University Third Hospital (No.M2020489).Written informed consent was obtained from each subject before any medical examination.Results:The OSDI differences between before and after treatment were 0.4(-5.6, 2.5) in tacrolimus group and 27.2(4.6, 45.0) in cyclosporine group, and the OSDI improvement was significantly greater in cyclosporine group than in tacrolimus group ( Z=-2.547, P=0.009).The differences of corneal fluorescein staining scores and BUT between before and after treatment were 5.0(2.5, 10.0) scores and 3.5(-0.5, 13.8) seconds in tacrolimus group, 0.0(-3.0, 0.0) scores and -1.5(-3.0, 0.0) seconds in cyclosporine group, respectively, with no significantly difference between both groups ( Z=-0.526, -0.804; both at P>0.05).The differences of IL-6, IL-8, IL-17, EGF and TNF-α expressions between before and after treatment in tacrolimus group and cyclosporine group were not significantly different ( Z=-0.487, -0.112, -0.412, -1.085, -1.198; all at P>0.05). Conclusions:Altered levels of all tested cytokines in oGVHD tears are of no significant differences between tacrolimus and cyclos porine treatment.In addition, 0.05% cyclosporine eye drops may be more comfortable than 1% tacrolimus for chronic oGVHD patients.

A series of novel indole-2-carboxylate derivatives were synthesized and assayed to determine their in vitro broad-spectrum antiviral activities. The biological results showed that some of the synthesized compounds exhibited potent broad-spectrum antiviral activity. Notably, compound 8f showed the highest SI value (17.1) to Cox B3 virus. Compound 14f showed both potent inhibitory activity against influenza A (IC50=7.53 μmol/L) and the highest SI value (12.1). SAR results showed that the alkyloxy at the 4-position of indole ring was not crucial to the antiviral activities. Incorporation of an acetyl substituent at the amino group disfavored antiviral activity towards RNA viruses.
