Objective To analyze the clinical diagnosis and therapeutic effect of primary middle lobe lung cancer,in order to provide evidence for clinical diagnosis and treatment.Methods The clinical data of 45 cases of primary middle lobe lung cancer treated by surgery from January 2002 to January 2007 were ana- lyzed retrospectively.The operation style includes:simple middle lobectomy 12 cases(26.7 %),middle or up- per lobectomy 10 cases(22.2 %),right lung total resection 5 cases(11.1%).Chest exploration was done on 2 cases(4.44 %),palliative resection or vedged resection 2 cases(4.44 %).Results 1 case died from lung in- fection and respiratory failure(2.22 %).15 cases with arrhythmia (33.3 %), 1 case with chylothorax were cured after conservative treatment.The survival rate of 1,3,5 year were 82.1%,64.3 %,32.1% respectively. Conclusion The treatment of primary middle lobe lung cancer is dominated by regular lobectomy. It is difficult to perform middle lobectomy,so double or total lobectomy is done generally.Owing to the more postoperative complications, it should be cautious to perform sleeve resection.It should be avoided to do vedged resection for primary middle lobe lung cancer in order to lessen local recurrence.

Chinese Journal of Postgraduates of Medicine 2021;44(3):197-201
Objective:To explore features and relevant influencing factor of ecological executive function in children with childhood absence epilepsy (CAE).Methods:Forty children with CAE (CAE group) and 40 healthy children with physical examination (control group) from April 2017 to July 2020 in Anhui Provincial Children′s Hospital were selected. The behavior rating inventory of executive function (BRIEF) parental questionnaire was used to evaluate the executive function of children. The differences of ecological executive function between 2 groups were compared.Results:The BRIEF total score, behavioral regulation index (BRI) and metacognition index (MI) in CAE group were significantly higher than those in control group: (52.03 ± 10.89) scores vs. (44.05±5.06) scores, (49.45 ± 9.93) scores vs. (43.85 ± 4.70) scores and (53.18 ± 11.24) scores vs. (44.95 ± 5.32) scores, and there were statistical differences ( P<0.01). Multiple stepwise regression analysis result showed that inhibit inhibition, shift, emotional control, initiation, working memory, planning, organization, monitoring, MI and total score were correlated with disease control ( P<0.01), and disease control had a negative predictive effect on them ( R2 = 0.174, 0.158, 0.234, 0.325, 0.383, 0.337, 0.378, 0.199, 0.463 and 0.435); BRI was correlated with onset age and disease control ( P<0.01 or <0.05), and onset age and disease control had a negative predictive effect on BRI ( R2 = 0.336). Conclusions:Children with CAE have ecological executive dysfunction. The control of the disease and the onset age are the main factors affecting the ecological executive function.

Dysfunction of the human 8-oxoguanine DNA glycosylase (hOGG1) is closely related to development of lung neoplasms and other cancers.Polymorphisms in hOGG1 gene may alter glycosylase activity,thereby affect its repair capacity to the damaged DNA,contributing to carcinogenesis.Joint effects of hOGG1 and other DNA repair gene SNPs have showed complex gene-gene interactions may significantly contribute to people's lung cancer susceptibility.HOGG1 plays an important role in maintaining mitochondrial respiration thus affects tumor cell growth.

Objective To investigate the changes in the number of synapses and neurons in the spinal dorsal horn in a rat model of phantom limb pain. Methods Eleven healthy adult SD rats of both sexes weighing 209-300 g were randomly divided into 2 groups: sham operation group (group S, n = 5) and phantom limb pain group (group P, n = 6). Phantom limb pain was induced by resection of a 0.5 cm segment of unilateral sciatic nerve in group P. In group S unilateral sciatic nerve was exposed but not transected. The animals were observed for autotomy and scored (0 = no autotomy, 13 = the worst autotomy) after operation and were sacrificed on the 28th day after operation. The L3-6 segment of the spinal cord was removed for determination of the number of neurons (by Nissl's staining) and synapses (by synaptophysin immuno-histochemistry).Results In group S no animal developed autotomy. In group P autotomy started from the 2nd day after operation and the score reached 9-11. The number of the neurons in the spinal dorsal horn in all 4 segments and the number of synapses in L3 and 16 segments were comparable between the two sides and the 2 groups. The number of synapses in the spinal dorsal horn of L4and L5 segment was significantly larger in the operated side than in the contralateral side in group P. Conclusion The number of synapses in the spinal dorsal horn significantly increases in animals with plantom limb pain which induces no increase in the number of neurons in the spinal dorsal horn.

Since 1970, 13 cases of reconstruction thumb and finger utilizing the second toe were performed. 13 out of 14 reconstructed digits survied with no complication. All wounds healed by primary intention. Emergency reconstruction has the following merits: it is completed in one stage, hence less suffering and economic loss to the patients;it promises early rehabilitation, early return to work and better functional results, as compared with delayed operation. Traumatic amputation of the thumb at or near the metacarpo-phalangeal joint with the transected part so badly injured that replantation is no longer fet-sible, and severe crushing injury of the thumb or all fingers are indicated for emergency reconstruction. Patient's age, occupation, desire for operation and general health should be considered individually before operation. The method of dissecting the second toe with the preservation of vasculization pattern of dorsalis pedis artery-first plantar metatarsal artery should be adopted in case the anatomic pattern of dorsal metatarsal artery belongs to Gilbert type Ⅲ.

· AIM: To study the inhibitory effect of pyrrolidine dithiocarbamate (PDTC) on the inflammatory reaction in an experimental proliferative vitreoretinopathy (PVR)model with laser flare cell meter (LFCM).· METHODS: A total of 20 pigmented rabbits were divided into two groups randomly, with 10 rabbits in each group. After the creation of retinal holes, 0.1mL PDTC was injected intravitreally into the right eyes of Group 1(A1) and the left eyes of Group 1 (A2), and 0.1mL balanced saline solution (BSS) into the right eyes of Group2 (B1). One hour later, 0.1mL BSS into the eyes of A1,and 5000U IL-1 β in 0.1mL BSS was injected intravreally into the eyes of A2 and B1. Clinical evaluation and LFCM examination were performed before retinal injury (PO)and at 4h, 24h, 1, 2 and 4wk after the second injection(P4h, P24h, Plwk, P2wk and P4wk). Histopathologic and immunohistochemical examination were also performed at these time points.· RESULTS: PDTC could inhibit the inflammatory reaction obviously from P24h to P2wk. The eyes of A1 and A2 recovered earlier than those of B1. Although inflammatory reaction in the 3 groups resolved completely by the end of P2wk measured with the slit-lamp microscope,the eyes of the B1 still showed obvious aqueous flare judged by the LFCM compared with those of A1 and A2.Histopathologic and immunohistochemical examination showed that nuclear factor- κ B (NF- κ B) was activated by IL-1 β and the PDTC had inhibitory effect on it without obvious toxicity to retina.· CONCLUSION: Inflammatory reaction involves in the rabbit model of PVR induced by injecting intravitreally IL-1 β and the PDTC can relieve it significantly. The LFCM provides a new, sensitive, objective and noninvasive method to quantify the inflammatory reaction in the PVR model.

? AIM: To investigate the differences between synoptophore and triple prism strabismometry and its possible cause.?METHODS: There were 347 patients with horizontal concomitant strabismus involved, in which 76 patients were esotropia, 37 patients were male while 39 were female, with average age of 13. 27 ± 7. 77 years old. There were 271 patients with exotropia, 131 cases were male while 140 were female, with average age of 15. 43 ± 8. 42 years old. All the patients were examined by synoptophore and prism plus shaded strabismometry in a long distance of 6m. Datas were analyzed by SPSS 17. 0.?RESULTS:In the exotropia patients, the conversions of circular degree(°) and prism degree(△) were:1°=0. 29△ ~1. 78△, which was statistically significant with intermittent strabismus (P=0. 001). While in the esotropia patients, the conversions were:1°=2. 01△ ~2. 15△.?CONCLUSION: The diversity between the two methods is enlarged with the increase of squint angle for exotropia patients. While in esotropia patients, the diversity decreased with the increase of squint angle. Synoptophore equipped with +7. 00D, defects of the triple prism itself and proximal convergence during exam may be the reasons for the diversity.
