Objective To explore the protective effect of a small balloon on bifurcation lesions by applying a single stent treatment of coronary bifurcation lesions strategy. Methods Fifty patients with coronary bifurcation lesions were randomly divided into A group and B group( 25 cases for each group ). Patients in A group were treated with the pre-entry protection branch guide wire to complete the main branch balloon pre-dilation,stenting,while in B group were treated with the set aside the branches of a small balloon. The information of main branch balloon pre-dilation,stenting were recorded. The blood flow slowed down,the incidence of side branch occlusion or stent placement,and the incidence of postoperative 24 h troponin I( cTnI) levels were measured. Results Nine cases(36%)in A group occurred lower branch blood flow,which due to 4 cases(16% )with significantly narrow branch stenting,2 cases(8%)with complete occlusion. There were only 2 cases(8%)with decrease branching blood flow in B group,and the difference was significant(P=0. 041, 0. 022). The cases with higher cTnI after 24 h in A group were 11( 39%),significantly higher in group B (3(12 %);P =0. 027 ). Conclusion Compared with the traditional protection guidewire,the approach of setting aside a small balloon to protect important branch can effectively prevent important branch occlusion, branch involvement due to lower incidence of myocardial infarction.

Objective:To explore the relationship between the type of mutation and clinical features, prognosis, and clinical characteristics of chronic granulomatous disease (CGD) caused by compound heterozygous mutations in the NCF2 gene in children. Methods:The clinical data of 1 case of neonatal CGD caused by compound heterozygous mutations of NCF2 gene at Tianjin Children′s Hospital in August 2019 was analyzed, and domestic and international literatures were searched to summarize the clinical characteristics, gene mutation type and prognosis of CGD caused by NCF2 mutation. Results:The diagnosis of CGD was confirmed by the presence of compound heterozygous mutations c. 196_197insA (p.Arg66Glnfs23X) and c. 1180T>G (p.Tyr394Asp) in the NCF2 gene, accompanied with the clinical manifestations of fever, cough, multiple clumps and nodules in the chest CT at 25 days after birth, and the neutrophil respiratory burst test stimulation index(SI) 23.This new mutation was not reported in the Human Genetic Mutation Database.The child had a residual portion of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity and was followed up until the age of 9 months with an antifungal drug without recurrent infection.A total of 101 cases of CGD patients with NCF2 gene mutation were reported in domestic and international databases.Totally, 33 cases had SI results, with 22 cases below 3, 11 cases above 3, and 8 cases of missense mutations. Conclusions:c. 196_197insA and c. 1180T>G are new mutations in NCF2 gene that can lead to CGD.CGD patients containing missense mutations in the NCF2 gene may have more residual NADPH oxidase activity.

Objective To validate a new standardized training program for urological surgeons to improve their laparoscopic surgical skills. Methods The laparoscopic surgical training program was carried out by using the traditional mechanical simulators and animal models. Thirty-three trainees participated the urological laparoscopic surgical training program. Initially, the novices were assigned to practise basic laparoscopic skills step by step on the simulator with fixed trocar positions. After a period of basic training, they were allowed to practise on animal models for some particular proce-dures. Results All trainees (33/33, 100.0%) participated were able to perform all basic techniques skillfully and completed laparoscopic anastomosis accurately after the training. The time required for performing the partial nephrectomy, dismembered pyeloplasty and ureteral reimplantation on animal models declined from 64.0±18.4, 127.54±17.5 and 75.84±11.6 min at the beginning to 30.94±3.8, 65.2±7. 5 and 37.7±7.2 min after practicing these procedures 8 times (P<0.01). They could un-derstand the crucial procedures of the laparoseopic surgeries after 6 to 8 special trainings on animal models. Fifteen trainees (15/33, 45.5%) had started to carry out laparoscopic surgeries after-finish- ing the training program. Conclusions Our program enables the participants to improve their techniques in complicated laparoscopic surgeries. The challenging parts of reconstructive laparoscopic surgeries such as laparoscopic dismembered pyeloplasty can be taught by using animal models. This program could be incorpo-rated easily by all urological departments developing a laparoscopie surgical training program.

OBJECTIVETo explore the potential effect of Guizhi plus Gegen Decoction (GGD) in improving learning and memory of lipopolysaccharides (LPS) induced neuroinflammatory mice and its possible mechanisms.
METHODSTotally 63 male ICR mice were randomly divided into 5 groups, i.e., the normal control (n = 13), the model group (n = 13), the low dose GGD group (n = 10), the high dose GGD group (n = 14), and the positive control group (n = 13). Mice were intraperitoneally injected with LPS (0.33 mg/kg) to induce Alzheimer's disease (AD) model. Mice in the high and the low dose GGD groups were administered with 12 g/kg or 6 g/kg by gastrogavage for 4 successive weeks. Mice in the control group were intraperitoneally injected with minocycline (50 mg/kg) for 3 days. By the end of treatment LPS were injected 4 h before behavior test each day, and then behavior test was conducted in mice of each group. Effect of GGD on learning and memory of AD mice was observed by using open field test, novel object recognition task, and Morris water maze.
RESULTSOpen field test showed there was no statistical difference in the movement time and the movement distance among all groups (P > 0.05), suggesting that LPS and GGD had no effect on locomotor activities of mice. In novel object recognition test, AD mice spent significantly shorter time to explore novel object after they were induced by LPS (P < 0.05), while for AD mice in the low and high dose GGD groups, their capacities for exploration and memory were significantly improved (P < 0. 05, P < 0.01). Results of Morris water maze showed that AD mice exhibited increased escape latency (P < 0.05) and spent much less time in swimming across the original platform (both P < 0.05). However, AD mice in the low and high dose GGD groups had obvious shortened latency and increased time percentage for swimming (P < 0.05, P < 0.01).
CONCLUSIONGGD possessed certain improvement in learning and memory disorder of LPS induced AD mice.

Objective To investigate the event-based prospective memory (EBPM) and time-based prospective memory (TBPM) in temporal lobe epilepsy patients,and test the hypothcsis that temporal lobe is involved in the prospective memory network. Methods Sixty-two patients with temporal lobe epilepsy (TLE) and 30 age- and education level-matched healthy adults were examed with the neuropsychological battery of tests including EBPM and TRPM tasks. Results In comparison with the controls,the TLE patients were impaired on MMSE,DS and VFT.Compared with the healthy adults ( EBPM:6.83± 1.34,TBPM:5.00 ± 1.70),the patients with temporal lobe epilepsy had a significant loss in EBPM (3.95 ±2.77,t =6.72,P <0.01 ) and TBPM (3.08 ±2.42,t =4.39,P <0.01).There was no difference in the performance of EBPM (3.82 ± 2.70,4.10 ± 2.90 ; t =- 0.40,P > 0.05 ) and TBPM (2.55 ± 2.20,3.69± 2.55; t =-1.90,P >0.05 ) between the patients with taking antiepileptic drugs and those without antiepileptic drugs. Conclusions These results suggest that patients with temporal lobe epilepsy may experience general difficulties with prospective memory.It is possible that temporal lobe is involved in the prospective memory network.The passages of TBPM need more self-initiated processes.
