Immune checkpoint inhibitors are members of a class of immune-suppressive molecules that regulate the strength and range of immune responses to avoid normal tissue damage. However, immune checkpoint activity can be stimulated by tumors to es-cape immune surveillance. To elicit anti-tumor effects, immune checkpoint inhibitors can promote the activation of T cells by blocking immune checkpoint proteins. Therefore, these inhibitors can be efficiently and safely used to treat solid tumors. Although the clinical usage of these inhibitors is in the initial stage, they have exhibited good efficacy and safety in lymphoma treatment. This review sum-marizes the biological activities of CTLA-4, PD-1, and PD-L1 and the application of antibodies as drugs for lymphoma treatment.

Objective To investigate the effects of exogenous hydrogen sulfide (H2S) on injury of rat hippocampus neurons induced by oxygen-glucose deprivation and restoration (OGD/R) and explore its mechanism.Methods Hippocampus neurons were isolated from embryonic day 16-18 (E16-18) rat embryos.Hippocampus was immediately removed and digested with 0.25％ trypsin.The neurons were isolated and cultured at 37 ℃ for 7 days and neuron-specific enolase (NSE) was detected by immunohistochemical staining method to identify neurons.At 8th day,the neurons were placed in deoxygenated glucose-free medium and exposed to 95％ N2-5％ CO2 in an air tight chamber for 1 hour,and then replaced the glucose-free medium with original medium,and returned the cultures to a standard incubator in 5％ CO2 at 37 ℃ and incubated for another 24 h.The neurons were divided into 3 groups:group Ⅰ control; group Ⅱ OGD/R,and group ⅢOGD + NaHS,the latter was further divided into 5 subgroups:groups Ⅲ1-5 with 25,50,100,200,400 μmol/L NaHS added,respectively.Then cell viability was quantified by MTT method,the level of lactate dehydrogenase (LDH) were detected,apoptosis was measured by Annexin V FITC/PI Apoptosis Kits,and RT-PCR was used to assay HIF-1 α mRNA in neurons in all groups.Results Compared with control group,the LDH level,apoptosis and expression of HIF-1α mRNA in group Ⅱ were significantly increased,the cell viability was significantly decreased (P ＜ 0.01).There were no significant differences in the LDH level,apoptosis and expression of HIF-1 α mRNA and the cell viability between group Ⅱ and group Ⅲ1 (P ＞ 0.05).Compared with group Ⅱ,the LDH level,apoptosis and expression of HIF-1α mRNA in group Ⅲ2-4 were significantly increased,the cell viability was significantly increased (P ＜ 0.01).Compared with group Ⅱ,the LDH level,apoptosis and expression of HIF-1 α mRNA in the group Ⅲ 5 were significantly decreased,the cell viability was significantly decreased (P ＜ 0.01).Conclusions H2S of low concentration has no significant effects on injury of rat hippocampus neurons induced by OGD/R.H2S of moderate doses can protect rat hippocampus neurons from OGD/R injury and H2S of high concentration can aggravate injury.The expression of HIF-1α mRNA in rat hippocampus neurons was increased after OGD/R,and the protective role of H2S is associated with increase in the expression of HIF-1α mRNA.

Objective To explore the effects of hydrogen sulfide (H2S) on apoptosis of cardiomyocytes after cardiopulmonary resuscitation (CPR) in rat models.Methods Forty-five male SD rats were randomly into sham group (n =15),CPR group (n =15) and NaHS group (n =15).Rats of CPR group and NaHS group were operated to induce cardiac arrest by transcutaneous electrical stimulation to epicardium.In NaHS group,NaHS (5 mg/kg) was administrated via the femoral venous line 1 min before CPR.Hemodynamic variables were monitored and obtained continuously.Survival rats were sacrificed at 24 h after restoration of spontaneous circulation and the hearts were removed for analysis by RT-PCR and TUNEL assays.Blood samples were collected and plasma content of cTnT was detected.Results Compared with the CPR group,animals treated with NaHS had improved left ventricular function (P ＜0.01),lower plasma cTnT levels (P ＜0.05) and decreased apoptosis index (P ＜ 0.01) 24 h after ROSC.The expressions of Caspase-3 mRNA,Bax mRNA and Bcl-2 mRNA in CPR group and NaHS group were higher compared with the control group (P ＜0.01).The NaHS group had lower expressions of Caspase-3 mRNA and Bax mRNA (P ＜0.01),but higher expression of Bcl-2 mRNA (P ＜0.05) compared with the CPR group.Conclusions Exogenous (H2S) regulated the expressions of Caspase-3,Bax and Bcl-2 mRNA,thereby preventing apoptosis of cardiomyocytes,inhibiting cTnT release and improving left ventricular function 24 h after CPR.

BACKGROUND:Some patients still have unsatisfactory improvement of operative limb fatigue and pain after total knee arthroplasty.Clinical findings show that Jianpi Yiqi Huoxue Formula can promote recovery after total knee arthroplasty,but the specific efficacy remains to be studied. OBJECTIVE:To observe the effect of Jianpi Yiqi Huoxue Formula on the muscle strength and pain of the operated limb after the primary unilateral total knee arthroplasty. METHODS:A total of 74 patients undergoing primary unilateral total knee arthroplasty were randomly divided into a trial group and a control group with 37 patients in each group.All patients received the same prostheses and surgical methods during the operation.Patients in the control group were treated with routine analgesics,anticoagulant drugs and functional exercise after the operation.The trial group received Jianpi Yiqi Huoxue Formula after the treatment in the control group.Both groups were treated continuously and followed up for 1 month.The changes in isokinetic muscle strength(peak torque and total work amount of extensor and flexor),visual analog scale score and the hospital for special surgery score of the two groups were analyzed. RESULTS AND CONCLUSION:(1)The trial group had better improvement in peak torque and total work amount of extensor and flexor and the hospital for special surgery score than the control group 14 days and 1 month after surgery(P<0.05).(2)In contrast to the control group,the visual analog scale score of the trial group improved better at 7 and 14 days and 1 month after surgery(P<0.05).(3)It is indicated that Jianpi Yiqi Huoxue Formula can effectively improve the muscle strength of the operated limb,enhance the degree of postoperative joint pain,and promote functional rehabilitation after total knee arthroplasty.

Objective:To explore the application value of guide tube fenestration and drainage technology in intracranial artery stenting surgery.Methods:A total of 120 patients with symptomatic intracranial atherosclerotic stenosis admitted to the Xingtai Third Hospital from January 2021 to December 2022 were selected and randomly divided into an observation group ( n=60) and a control group ( n=60). Both groups were treated with intracranial artery stenting, with the observation group receiving guidance catheterization and window opening technique during the surgery. Two groups of surgeries were observed and compared: the degree of vascular stenosis before and after surgery, the Montreal Cognitive Assessment Scale (MoCA) scores before and one month after surgery, intraoperative complications, and prognosis. Results:The surgical time and catheter placement time in the observation group were (110.20±23.32)minutes and (11.32±2.01)minutes, respectively, which were significantly shorter than those in the control group (all P<0.05). The stent placement rate and operation success rate in the observation group were 95.00% and 96.67%, respectively, significantly higher than those in the control group (all P<0.05). The degree of postoperative vascular stenosis in the observation group was (32.29±7.11)%, significantly milder than that in the control group [(44.43±8.15)%, P<0.05]. One month after surgery, the MoCA scores of both groups improved significantly compared to before surgery (all P<0.05), and there was no statistically significant difference between the groups ( P>0.05). There was no statistically significant difference in the incidence of collateral circulation occlusion and vascular rupture between the two groups (all P>0.05). During the follow-up period, there was no statistically significant difference in the incidence of restenosis, intracranial hemorrhage, and recurrent ischemic stroke between the observation group and the control group (all P>0.05); The good prognosis rate of the observation group was 73.33%, significantly higher than that of the control group (53.33%, P<0.05). Conclusions:The application of guided catheter fenestration technique in intracranial artery stenting has good value, which is beneficial for improving the stent placement rate and operation success rate, and improving the degree of vascular stenosis.

OBJECTIVE：To investigate the accessibility of antibiotics in essential medicine list in medical institutions of Nanjing area ，and to provide reference for formulating and improving related drug policy. METHODS ：Taking the original and imitated drugs as the objects of investigation ，the standard investigation method jointly formulated by WHO/HAI was adopted to select 35 kinds of antibiotics which were included in Essential Medicine List （2018 edition）and International Drug Price Indicator Guide（2015 edition），and to investigate 3 dimenions such as the availability （proportion of institutions that could provide this drug），price（calculated by MPR ）and affordability （the ratio of drug expenditure to the daily minimum wage of non-technical government workers ）of them in 13 second-class or above medical institutions in Nanjing area by online questionnaires during Jan.-Jun. 2019，so as to put forward the suggestions for drug policy formulation. RESULTS ：The median availability of original drugs was 0，with a range of 0 to 100％；the median availability of generic drugs was 30.80％，with a range of 0 to 100％. The median MPR of original drugs was 5.54，with a range of 1.96 to 18.83；the median MPR of generic drugs was 1.76，with a range of 0.16 to 7.66. Median affordability of original drugs was 8.68，with a range of 1.19 to 41.79；the median affordability of generic drugs was 0.52， with a range of 0.03 to 16.80. CONCLUSIONS：Generic drugs are more available than the originals. The price of original drugs is generally very high ， while the price of generic drugs is mostly cheaper. The affordability of original drugs is really poor ， and the 规。E-mail：shaorong118@163.com affordability of generic drugs is totally good. There are stillrooms for further improvement in the overall accessibility of essential medicines. At present ，ensuring the accessibility of original drugs may be more helpful to meet the needs of treatment. It is suggested to update and adjust the essential medicine list based on the clinical medication requirement ，popularize the knowledge about essential medicines ，properly adjust the price of original drugs and ease the treatment burden of patient. It is supposed to take into full consideration about the regional factors and the needs of different medical institutions when making drug policy.

ObjectiveTo test the inter-tester reliability and test-retest reliability of MyotonPRO for evaluating neck and shoulder muscle performance parameters in patients with unilateral chronic neck pain, observe the difference of muscle performance between the healthy and affected sides of patients with chronic neck pain, and analyze the factors that cause the imbalance of muscle performance in patients with chronic neck pain. MethodsFrom January to June, 2023, 32 patients with unilateral chronic neck pain in Guangdong Second Traditional Chinese Medicine Hospital were selected. Two testers used the same MyotonPRO equipment to measure the muscle tone, muscle hardness and muscle elasticity on both sides of the sternocleidomastoid muscle and the upper trapezius muscle in the relaxed position. Tester 1 repeated the measurement after an interval of 30 minutes, and Tester 2 was measured within the time interval between the two measurements of Tester 1. The intraclass correlation coefficient (ICC), standard error of mean (SEM) and minimum detectable change (MDC) were calculated simultaneously. The measurement results were plotted into Bland-Altman diagram and systematic bias analysis was performed. The difference in muscle characteristics between the affected side and the healthy side was compared. At the same time, the Visual Analogue Scale (VAS) score and body mass index (BMI) of the subjects were collected for correlation analysis. ResultsExcept the sternocleidomastoid muscle elasticity of the affected side (ICC = 0.697), the inter-tester reliability of all other parameters was high to very high (ICC = 0.719 to 0.952, SEM = 0.04 to 6.53, MDC = 0.12 to 18.11). The test-retest reliability of all parameters was high (ICC = 0.883 to 0.981, SEM = 0.03 to 5.72, MDC = 0.09 to 15.84). Bland-Altman plot analysis showed that the scatter distribution was consistent. The muscle tone, muscle hardness and muscle elasticity of sternocleidomastoid muscle and upper trapezius muscle were higher on the affected side than on the healthy side (t > 2.846, P < 0.05). The asymmetry index of tension, hardness and elasticity of upper trapezius muscle and sternocleidomastoid muscle was significantly positively correlated with VAS score and BMI (r > 0.385, P < 0.05). ConclusionMyotonPRO has good inter-tester reliability and retest reliability in evaluating the muscle performance of both sides of patients with chronic neck pain. The muscle tone, muscle hardness and muscle elasticity of sternocleidomastoid muscle and upper trapezius muscle on the affected side were higher than on the healthy side, and the difference of muscle performance was positively correlated with pain and BMI.
