Objective To evaluate the relationship between erythroid 2-related factor (Nrf2 )-antioxidant response element (ARE) pathway and acute lung injury (ALI) induced by endotoxic shock in rabbits .Methods Thirty healthy male New Zealand white rabbits ,aged 2 months ,weighing 1.5-2.0 kg ,were randomly divided into 3 groups (n=10 each) using a random number table :control group (group C) ,group ALI and all-trans retinoic acid group (group ATRA ) .In group ATRA ,all-trans retinoic acid 6 mg/kg (in filter sterilized vegetable oil 1.2 ml) was injected intraperitoneally once a day for 2 days .ALI was induced by lipopolysaccharide 5 mg/kg (in normal saline 2 ml ) injected via the auricular vein at 10 h after the last injection of ATRA in ALI and ATRA groups .The equal volume of normal saline was injected instead in group C .The rabbits were sacrificed at 6 h after lipopolysaccharide or normal saline administration .The pulmonary specimens were removed for determination of wet/dry lung weight ratio (W/D ratio ) and expression of Nrf2 mRNA and nuclear protein ,and HO-1 mRNA and protein in lung tissues .The pathological changes of lungs were scored .Results Compared with group C ,the pathological score and W/D ratio were significantly increased , and the expression of Nrf2 mRNA and nuclear protein ,and HO-1 mRNA and protein was up-regulated in ALI and ATRA groups ( P<0.05 ) .Compared with group ALI ,the pathological score and W/D ratio were significantly increased ,the expression of HO-1 mRNA and protein was down-regulated ( P<0.05) ,and no significant change was found in the expression of Nrf2 mRNA and nuclear protein in group ATRA ( P> 0.05 ) .Conclusion Activation of Nrf2-ARE pathway is the regulatory mechanism of the body adapting to the ALI induced by endotoxic shock in rabbits .

Objective:To observe the locoregional recurrence and survival of stageⅢA-N2 non-small cell lung cancer (NSCLC) after in-duction chemotherapy and surgery, to analyze the prognosis influenced by nodal downstaging, and to explore the necessity for postop-erative radiotherapy. Methods:A total of 116 cases of stageⅢA-N2 NSCLC were treated with induction chemotherapy and surgery be-tween January 2009 and June 2014. These cases underwent R0 resection. Kaplan-Meier method was employed to calculate the local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and overall survival (OS) of the patients. Log-rank test was con-ducted to compare the differences between groups. Cox models were used to perform multivariate analysis. Results:The median fol-low-up of the patients was 24.42 months. The numbers of patients with pN0, pN1, and pN2 were 40 (34.5%), 16 (13.8%), and 60 (51.7%), respectively. The 3-year local recurrence rates of patients with pN0, pN1, and pN2 were 27.5%, 56.2%, and 51.7%, respectively. In the group treated with adjuvant chemotherapy, the 3-year local-recurrence rates of patients with pN0, pN1, and pN2 were 26.9%, 58.3%, and 46.2%, respectively. Multivariate analysis revealed that the significant predictor of LRFS was pN0 during the surgery. The LRFS of patients with pN0 was greater than that of the patients with pN1 (P=0.048). The LRFS of patients with pN1 was not significantly associated with that of patients with pN2 (P=0.314). The 5-year OS rate of the groups was 46.6%. The multivariate analysis also demon-strated that pT1, pN0-1, and induction chemotherapy effects were associated with OS. The patients with pN2 yielded a poorer OS than those with pN0 and pN1 (P<0.05). The patients with pN0 did not significantly differ from those with pN1 in terms of OS (P=0.412). Conclu-sion:Although the occurrence of pathologic downstaging is a well-known positive prognostic indicator after stageⅢ-N2 NSCLC is sub-jected to chemotherapy, the local-recurrence rate of nodal-downstaged patients remains high, even when they receive adjuvant che-motherapy. Therefore, new postoperative strategies after induction chemotherapy and surgery should be developed.

Objective To evaluate the correlation of different fractionation schedules in radiotherapy with the local control ( LC) and overall survival ( OS) rates in patients with extensive?stage small cell lung cancer ( ES?SCLC ) , and to figure out the relationship between different fractionation schedules in radiotherapy and the prognosis of ES?SCLC. Methods One hundred and ten patients newly diagnosed with ES?SCLC from February 2010 to March 2015 received chemoradiotherapy. According to the radiation dose, all patients were divided into hypo?fractionation group ( 30?45 Gy/3 Gy/10?15 f, n=31) and conventional fractionation group ( 54?60 Gy/1?8?2?0 Gy/27?30 f, n=79) . In all patients, 90?9% had stageⅣSCLC;21 patients had brain metastasis;39 patients were treated with prophylactic cranial irradiation ( PCI ) . The Kaplan?Meier method was used to calculate the survival time and log?rank test was used for between?group comparison. Between?group comparison of categorical data was made by χ2 test. Results The number of patients followed?up were 85 at 2?years. In all patients, the 2?year OS, progression?free survival ( PFS) , and LC rates were 27?7%, 17?5%, and 38?9%, respectively. The hypo?fractionation group had similar prognosis to the conventional fractionation group. There were no significant differences in the 2?year OS, PFS, and LC rates between the two groups ( 35% vs. 26%, P=0?886;18% vs. 16%, P=0?560;67% vs. 36%, P=0?159) . There was also no significant difference in the 2?year OS rate between patients treated with and without PCI (44% vs. 18%, P=0?044). In 84 patients with treatment failure, 11 had local recurrence, 41 had distant metastasis, and 32 had local recurrence plus distant metastasis. Conclusions The hypofractionated radiotherapy has similar efficacy but substantially shortened radiation time compared with conventionally fractionated radiotherapy. The palliative hypofractionated radiotherapy requires further study for ES?SCLC.

"Good doctor" plus "good patient" do not necessarily mean "good doctor-patient relationship", but both are the basis for building a harmonious doctor -patient relationship and neither of the two can be dis-pensed. This paper conducted a comparative study on ideal and realistic doctor-patient relationship, digged and refined the characteristics of"good doctor" and"good patients", and agreed that it was possible to construct a har-monious doctor-patient relationship when doctors pursued professional excellence and moral integrity, and patients had good "patient literacy".

Objective:To evaluate the efficacy of proximal humerus internal locking system (PHILOS) via the minimally invasive plate osteosynthesis (MIPO) in the treatment of proximal humeral fractures.Methods:This retrospective study analyzed 30 elderly patients with proximal humeral fracture who had been treated by PHILOS via MIPO from September 2016 to March 2020 at Department of Orthopedic Surgery, People’s Hospital of Zhuxi County. They were 19 females and 11 males with an average age of 60.96 years (from 45 to 80 years). All patients were treated by closed reduction. After fracture reduction was confirmed by fluoroscopy, a minimally invasive incision was made below the acromion, with a couple of suture wires reserved at the rotator cuff attachments. A PHILOS plate was inserted at 4 mm lateral to the intertubercular sulcus, with the suture wires passing through the proximal suture holes on the PHILOS. After a lag screw was first screwed up into the compression hole on the PHILOS plate, the crossing suture wires were tightened up to resist the rotator cuff stress and maintain the internal inclination of the humeral head. Kirschner wires were used to temporarily stabilize the reduction. After satisfactory reduction and fine plate positions were confirmed by fluoroscopy, locking nails were screwed up. The internal inclination of the affected humeral head was compared between preoperation and the last follow-up. The therapeutic efficacy was evaluated by the shoulder Neer scoring system, and the visual analogue scale (VAS) pain scores and complications were recorded at the last follow-up.Results:All the 30 patients were followed for 6 to 18 months (average, 12 months). There was no incision infection, neurovascular injury, or internal fixation failure. Anatomical reduction was achieved in 25 patients and functional reduction in 5. The inclination of the humeral head was significantly improved. The VAS scores at the last follow-up averaged 1.9. Follow-up X-ray examination showed that bony union was achieved after 6 to 18 months (average, 9 months) for all patients. At the last follow-up, the inclination angle of the affected humeral head was 130°±5°, significantly improved compared with the preoperative 90°±11.2° ( P<0.05). All patients had good functional recovery of the shoulder. The efficacy was, according to the Neer shoulder scores at the last follow-up, excellent in 22, good in 6 and fair in 2 cases. Conclusions:Treatment of proximal humeral fractures using PHILOS via MIPO technique is suitable for patients with osteoporotic fracture, and may lead to fine therapeutic efficacy.
