OBJECTIVE: To explore the peripheral neural mechanism underlying representation along the distribution of stomach meridian induced by intestinal inflammatory reaction using diarrhea predominant-irritable bowel syndrome (IBS-D) mice. METHODS: Among 62 healthy male C57BL/6 mice of clean grade, 12 mice were randomly selected and divided into a control group and a model group, 6 mice in each group, additionally, 12 mice were randomly selected and divided into a Tianshu group, a Liangqiu group and a Zusanli group, 4 mice in each group. In the model group, citrobacter was administered orally to establish IBS-D model. In the control group and the model group, the visceral pain threshold was observed using fecal colorectal distension (fCRD) induced electromyography of external oblique muscle, the positive cell number of neutrophil in the colonic muscularis was detected by myeloperoxidase (MPO) staining, the number, location and distribution rule of Evans blue (EB) extravasation points were observed by injection of EB staining solution into the tail vein. In the Tianshu group, the Liangqiu group and the Zusanli group, fluorescent dye Dil was injected at bilateral "Tianshu" (ST25), "Liangqiu" (ST34) and "Zusanli" (ST36) respectively, to observe the dye-positive cell number in different dorsal root ganglion (DRG) segments. In the control group and the model group, the activation of satellite glial cells (SGCs) in different DRG segments was observed by immunofluorescence. RESULTS: Compared with the control group, in the model group, the area under curve of electromyography of external oblique muscle was increased at fCRD of 25, 50 and 75 μL distilled water (P<0.001, P<0.01); the MPO-positive cell number of neutrophil in the colonic muscularis was increased (P<0.01). Few EB extravasation points could be found in the control group, while there were much more EB extravasation points observed in the model group, which was specially distribution in the area of stomach meridian, from "Huaroumen" (ST24) to "Zusanli" (ST36), as well as the surface area dominated by L₂-L₅ segment of the spinal cord. The Dil-positive cells were mainly exhibited in the DRG of T₁₁, L₅ and L₄ segments in the Tianshu group, the Liangqiu group and the Zusanli group, respectively. Compared with the control group, the ratio of glial fibrillary acidic protein (GFAP)/glutamine synthetase (GS) co-expression was increased in the DRG of T₁₁, L₄ and L₅ segments in the model group (P<0.05, P<0.01). CONCLUSION The activation of SGCs within DRG of T₁₁, L₄ and L₅ segments may relate closely to the occurrence of the representation along the stomach meridian distribution in IBS-D mice.

Objective To investigate the effect of combination of rope-assisted proprioceptive neuromuscular facilitation(PNF)training and rope-assisted brain-computer interface(BCI)training on upper limb function in stroke patients with hemiplegia. Methods From March,2022 to February,2023,96 inpatients with stroke hemiplegia from the Second Affiliated Hospital of Guangxi Medical University were randomly divided into conventional group(n=32),PNF group(n=32)and combined group(n=32).All the groups received routine rehabilitation treatment.The conventional group re-ceived upper limb PNF training,the PNF group received upper limb rope-assisted PNF training,and the com-bined group received both upper limb rope-assisted PNF training and upper limb rope-assisted BCI training,for four weeks.They were assessed with Functiongal Test for the Hemiplegic Upper Extremity-Hong Kong version(FTHUE-HK),Fugl-Meyer Assessment-Upper Extremities(FMA-UE)and modified Barthel Index(MBI)before and after treatment. Results The intra-group effect(F>341.219,P<0.001),inter-group effect(F>21.705,P<0.001)and interaction effect(F>3.171,P<0.05)were significant in the scores of FTHUE-HK and MBI.The intra-group effect(F=520.472,P<0.001)and inter-group effect(F=41.939,P<0.001)were significant in the scores of FMA-UE,and the interaction effect was not(P>0.05).After treatment,the FTHUE-HK,FMA-UE and MBI scores were the best in the combined group(P<0.05). Conclusion The combination of rope-assisted PNF training with rope-assisted BCI device training could further improve the motor function of the upper limbs in stroke patients with hemiplegia,and enhance their activities of daily liv-ing.

Tyrosine kinase inhibitor (TKI) have been proved to be effective in the treatment of advanced non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) sensitive mutation, which is superior to chemotherapy. However, there are still some patients with sensitive mutations have primary drug resistance. It may be related to the coexistence of susceptible and resistant mutations of EGFR gene, downstream mutations of EGFR pathway, MET amplification and BIM deletion polymorphism. We present 2 cases of primary drug resistance and analyze the reasons.

Objective To access the value of MRI in differential diagnosis between intrahepatic cholangiocarcinoma and atypical hepatic abscess. Methods Retrospectively collecting and analyzing the clinical and MRI imaging data of 19 patients with intrahepatic cholangiocarcinoma (ICC) and 17 patients with atypical hepatic abscess, confirmed by reexamination after anti‐inflammation therapy, surgery or puncture etiology, from June 2011 to July 2018 in Central Hospital of Lishui City.They were divided into ICC and abscess groups.All patients underwent routine liver plain MRI, DWI and contrast‐enhanced MR scan. The MRI features of the two groups (including morphology, boundary, cystic change and necrosis, pseudocapsule, hemorrhage, lipid composition, the signature of lesion in different phases of MRI and surrounding tissue) were studied. Fisher exact test and t test were used. Result This study showed that there was statistical difference between the two groups in the following aspects, the presence of cystic degeneration, the degree of annular enhancement in arterial phase, the homogeneous enhancement in portal venous phase and balanced phase and the central filling enhancement sign (P<0.05).The results showed that necrotic cystic lesion was more common in the abscess group (15/17 cases) than in the ICC group (0/19 cases);in the cases with annular enhancement in arterial phase,the degree of enhancement in the ICC group (13/16 cases) was higher than that in the abscess group (2/9 cases); the enhancement of the central parenchyma of lesion on out‐of‐phase images (1/19 cases) was slower in the ICC group than that in the abscess group (14/17 cases);and the ICC group was likely to present as central filling enhancement compared to the abscess group. Conclusion The presence of cystic lesions in DWI, the enhancement degree of marginal parenchyma, the enhancement speed of central parenchyma and the whole enhancement pattern are essential signs for differentiating intrahepatic cholangiocarcinoma and atypical hepatic abscess. 图1 女,53岁,右肝脓肿.病灶最大径4.0 cm,病灶中的小囊变区在DWI上呈高信号(↑) 图2 女,39岁,右肝脓肿.病灶最大径3.1 cm,病灶中的小囊变区在DWI上呈高信号(↑) 图3 女,66岁,右肝肝内胆管细胞癌(ICC).病灶最大径5.3 cm,横轴面T2WI病灶整体呈不均匀高信号,内见相对更高信号的富黏液区(↑) 图4 男,45岁,右肝ICC.病灶最大径5.8 cm,横轴面T2WI病灶整体呈高低混杂信号,内见散在片状低信号的凝固性坏死区(↑) 图5 与图1为同一患者.横轴面T2WI病灶实质部分呈均匀高信号,小囊变区呈明显高信号(↑) 图6 与图2为同一患者.横轴面T2WI病灶实质部分呈等信号,小囊变区呈明显高信号(↑)图7 与图3为同一患者.增强扫描动脉期横轴面示病灶边缘轻度不规则环形强化 图8 与图4为同一患者.增强扫描动脉期横轴面示病灶强化环有多处中断征象(↑) 图9,10 男,45岁,右肝ICC.病灶最大径5.8 cm,增强扫描动脉期横轴面(图9)示病灶边缘局部显著环形强化,局部强化环明显中断(↑).平衡期横轴面像(图10)示病灶中央有填充强化 图11 与图3,7为同一患者.平衡期横轴面示病灶内富黏液区出现轻微中央填充强化(↑) 图12 与图4、8为同一患者.平衡期横轴面像示病灶中央有填充强化 图13,14 男,59岁,右肝脓肿.病灶最大径4.3 cm,动脉期横轴面像(图13)示脓壁散在强化,周围见片状异常灌注.平衡期横轴面像(图14)示脓壁均匀强化,其内囊变区无强化 图15 与图2,6为同一患者.平衡期横轴面像示脓壁均匀强化呈相对等信号,其内囊变区无强化(↑) 图16 与图1,5为同一患者.平衡期横轴面像示脓壁均匀强化呈相对等信号,其内囊变区无强化(↑)

Objective To discuss the influence of preoperative family purge care for the quality of life of patients with long type of congenital Hirschsprung′s disease (HD) who had enterocolitis history in neonatal period. Preoperative family purge care, which can shorten the HD postoperative treatment, improve the quality of life. Methods A total of 40 cases of patients with long type of congenital HD who had enterocolitis history in neonatal period received 1-stage radical preoperative by family phone call. Nineteen cases from January 2010 to February 2013 were as normal group and 21 cases from March 2013 to April 2016 were as improved group. Routine family purge nursing care 3-6 months were used in both the groups, while the combined nursing care of expanding anus were used in the improved group in addition. Evaluated the effects of postoperative observation indicates: the first defecation time, length of hospital stay, time needed for expanding anus, patency rate of defecation and not patency rate in 9-12 days, need enema intervention to assist defecate rate after postoperative 1 year, the recurrence of enterocolitis at 1-3 years after operation. Results The first defecation time, length of hospital stay, time needed for expanding anus were (39.15±8.23) h, (7.89±0.82)d, (5.17±0.98) min in normal group, (23.79± 7.54) h, (7.10± 0.29) d, (3.15±0.73) min in improved group, and there were significant differences between two groups (t=6.13, 5.46, 15.54, all P<0.01). The patency rate of defecation and not patency rate in 9-12 days were 12/19, 7/19 in normal group, 100.00%(21/21), 0 in improved group, and there were significant differences between two groups (χ2=9.38, P<0.01). The intervention rate of no need for enema, occasionally enema, often enema were 2/19, 12/19, 5/19 in normal group, 76.19%(16/21), 23.81%(5/21), 0 in improved group, and there were significant differences between two groups (χ2=18.25, P<0.01). There was no significant difference in the recurrence of enterocolitis at 1, 2, 3 years after operation between two groups (χ2=2.33, P>0.05). Conclusions Patient with long type of congenital HD who had enterocolitis history in neonatal period neonatal period,received family enema and expanding anus in 3- 6 months before 1-stage radical preoperative can shorten the postoperative HD treatment, improve the quality of life.
