Background The incidence and progression of glaucomatous optic neuropathy is related to a disturbance of the retrobulbar hemodynamics.Compound anisodine is clinically applied for the treatment of ischemic ocular diseases.Objective To evaluate the effects of compound anisodine injection on the ocular blood flow of glaucoma patients.Methods Twenty-one patients with primary glaucoma were divided into the treatment group and the control group.The eyes of each patient in the treatment group were selected further into the treatment eye group (11 eyes with greater mean deviation [MD]) or the opposite eye group(11 eyes with lesser MD).One of the eyes of each patient in the control group with MD value were selected as control eyes (10 eyes).The treatment eye group received compound anisodine on the para-superficial temporal artery via subcutaneous injection once a day for 2 treatment periods (each period equals 14 days,with 7 days intermittent between periods,totally 35 days) in addition to routine treatment.The retrobulbar blood flow,optic disc data,refraction error,visual field and intraocular pressure were measured in 3 time points:Before treatment period (baseline test),one day after treatment period (the 1st postreatment test) and 35 days after treatment period (the 2nd posttreatment test).Results Compared with the control group,the peak systolic velocity (PSV) and end diastolic velocity (EDV) of short posterior ciliary artery (SPCA) of the treatment eye group were relatively increased significantly in the 1st posttreatment test (P =0.017,0.028),the PSV of SPCA of the opposite eye group was relatively increased significantly in the 1 st posttreatment test (P =0.049),the EDV of central retinal artery (CRA) of the opposite eye group was relatively increased significantly in the 2nd posttreatment test (P =0.035).In contrast to the treatment eye group,the inferior quadrant RNFL thickness of the optic disc decreased significantly in the 2nd posttreatment test in the control group (P =0.009),the 6 o'clock RNFL thicknesses of the optic disc decreased significantly in the 1 st posttreatment test in the control group (P =0.014),and the 6 o'clock and 7 o'clock RNFL thicknesses of the optic disc decreased significantly in the 2nd posttreatment test in the control group (P =0.029,0.011).Conclusions The application of compound anisodine for the treatment of primary glaucoma relatively increases the PSV and EDV of SPCA.

Objective To discuss the effect and safety about large dosage of tilofiban injection into coronary artery in patients with ST-segment elevated myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods A prospective study was conducted. Two hundred and eighteen patients with STEMI admitted into Cardiology Department of Taizhou Central Hospital were enrolled. According to the difference in dosage, they were divided into a large dosage tilofiban group (102 cases) and a routine dosage tilofiban group (116 cases). In both groups, they received the injection of load dosage of tilofiban into coronary artery during they underwent primary PCI, the load dosage being 25μg/kg in the large dosage group, and 10μg/kg in the routine dosage group. Afterwards, the dosage was kept on 0.15μg·kg-1·min-1 in both groups lasting for 18-24 hours. The flow of thrombolysis in myocardial infarction (TIMI) immediately after PCI, the return of ST-segment after operation for 2 hours, the rate of bleeding events, the rate of major adverse cardiac event [MACE, including death, re-infarction and target vessel revascularization (TVR)] and prognosis after operation for 30 days were observed. Results The ratios of the immediate reflow of TIMI 3 grade after operation and the return of ST-segment after operation for 2 hours in the large dosage tirofiban group were higher than those in the routine dosage tirofiban group [the ratio of the reflow of TIMI 3 grade:92.16%(94/102) vs. 81.90%(95/116), the ratio of the return of ST-segment after operation for 2 hours:89.22%(91/102) vs. 73.28%(85/116), both P < 0.05]. The ratios of re-infarction, TVR and the total MACE in 30 days after operation in large dosage tirofiban group were lower than those in the routine dosage tirofiban group [re-infarction: 0.98% (1/102) vs. 2.59% (3/116), TVR: 0.98% (1/102) vs. 2.59% (3/116), total MACE: 1.96% (2/102) vs. 6.03% (7/116), all P < 0.05]. There were no statistically significant differences in mortality and the bleeding events between the large dosage tirofiban group and routine dosage tirofiban group [mortality:0 (0/102) vs. 0.86%(1/116), bleeding events:1.96%(2/102) vs. 0.86%(1/116), both P>0.05]. Conclusion The injection of a large dosage of tilofiban into a coronary artery in patients with STEMI undergoing primary PCI is an effective and safe method to allow them to get more clinical benefits.

Based on the requirements of military professional education reform and in view of the problems existing in the operation and maintenance of first-aid medical equipment in grass-roots forces. We put forward a construction scheme of online course which named operation and maintenance of first-aid medical equipment in grass-roots forces, and then expound the scheme from teaching content construction and teaching mode construction. The teaching content construction consists of two parts: the management theory of conventional medical equipments and the operation and maintenance teaching of specific first-aid medical equipments. In the construction of teaching mode, we elaborate on the organization forms of teaching, answering questions, training and examination units in detail. The design scheme of the online course is in line with the learning characteristics and meets the demand of learning the knowledge of the operation and maintenance of first-aid medical equipment systematically, so as to improve the post competency of the grass-roots forces.

Objective:To investigate the clinical efficacy of fixed-bearing unicompartmental knee arthroplasty (UKA) in the treatment of anteromedial knee osteoarthritis or spontaneous osteonecrosis of the femoral condyle.Methods:Between June 2017 and June 2018, 62 consecutive patients were treated at Department of Joint Surgery, Fuzhou Second Hospital Affiliated to Xiamen University for anteromedial knee osteoarthritis or spontaneous osteonecrosis of the femoral condyle using a fixed-bearing UKA system. They were 27 men and 35 women, aged from 58 to 85 years (average, 69.8 years). There were 58 cases of anteromedial knee osteoarthritis and 4 cases of spontaneous osteonecrosis of the femoral condyle. The courses of disease ranged from 2 to 10 years (average, 5.1 years). Medial unicompartmental knee arthroplasty was performed for all the patients on the fixation platform SLED. Recorded were the hip-knee-ankle angle (HKA) of the patients 2 days after operation, Oxford knee score (OKS) and American Knee Society score (KSS) at the final follow-up and post-operative complications.Results:The 62 patients were followed up for 9 to 21 months (average, 15.6 months). Tibial plateau fracture occurred in one case who eventually obtained bony union after open reduction and internal fixation. Another case had a wound healing problem which responded to drainage and debridement with prosthesis preservation. Another case presented prepatellar pain which was improved after physical therapy. In the 62 patients, the HKA 2 days after operation (172.27°±1.61°) was significantly improved compared to the preoperative value (177.79°±1.32°), the OKS at the final follow-up (19.8±2.7) significantly lower than the preoperative value (50.2±3.1), and the KSS at the final follow-up (89.7±2.6) significantly higher than the preoperative value (49.6±5.2) (all P<0.05). Follow-ups revealed no cases of joint infection or prosthetic loosening. Conclusion:Fixed-bearing unicompartmental knee arthroplasty can lead to fine short-term outcomes for anteromedial knee osteoarthritis or spontaneous osteonecrosis of the femoral condyle.

Objective:To explore the safety and therapeutic effect of programmed death 1 (PD-1) antibody combined with chemotherapy as a neoadjuvant therapy for patients with stage Ⅱ to Ⅲ non-small cell lung cancer (NSCLC).Methods:Thirteen patients, who had been diagnosed as stage Ⅱ-Ⅲ NSCLC and received PD-1 inhibitor plus chemotherapy as a neoadjuvant treatment in National Cancer Center/Cancer Hospital were recruited. The patients received consecutive neoadjuvant chemotherapy for 21 days as a cycle and the therapeutic efficacy was evaluated after two cycles.Results:At the last time of follow-up on December 2, 2019, the objective response rate (ORR) and disease control rate (DCR) of these patients were 61.5% (95% CI 30.9%-92.1%) and 100%, respectively. The downregulation rate of disease stage was 61.5% (8/13). The resectable rate was 38.5% (5/13), among them, the major pathologic response (MPR) was 60.0% (3/5) and the complete pathologic response (CPR) was 20.0% (1/5). The neoadjuvant chemotherapy displayed a low incidence of adverse reaction. The main grade 3 to 4 toxicities were neutropenia (38.5%) and leukopenia (23.1%). There was no significant immune-related toxicity. The safety and tolerability of perioperative period of patients underwent resection were promising. Conclusions:Immunotherapy combined with chemotherapy as a neoadjuvant treatment is an effective, low-toxicity treatment manner, which has perioperative safety and high rate of MPR for patients with resectable NSCLC. It is a promising treatment option for patients with stage Ⅱ to Ⅲ NSCLC.

Transient receptor potential vanilloid-1(TRPV1) channel is a non-selective ligand-gated cationic channel with multiple activation mechanisms in the transient receptor potential subfamily. In recent years, a large number of studies have found that TRPV1 plays an important role in the field of cardiovascular diseases such as hypertension and atherosclerosis. With the in-depth study of traditional Chinese medicine, it has been found that Chinese medicine monomers and their active components can activate or inhibit TRPV1 channels, which has certain potential in the study of cardiovascular diseases. In this paper, the role of TRPV1 channel in cardiovascular diseases and the research progress of traditional Chinese medicine prevention and treatment of cardiovascular diseases based on TRPV1 channel are reviewed, in order to provide new ideas for prevention and treatment of cardiovascular system diseases.
