Objective:To explore the efficacy of central combined peripheral dual-target magnetic stimulation on Parkinson disease (PD) patients with freezing of gait (FOG).Methods:A total of 39 patients with FOG diagnosed at the Parkinson disease clinic of the Affiliated Hospital of Nantong University were included in the study from July 2022 to September 2023.They were randomly divided into observation group ( n=20) and control group ( n=19) by the random number table method. The patients in control group were treated with repetitive transcranial magnetic stimulation (rTMS), while the patients in observation group were treated with additional repetitive peripheral magnetic stimulation(rPMS) on the affected tibialis anterior muscle on the basis of the control group. Other clinical medical treatments were the same for both groups of patients.The timed up and go test (TUGT), 10 meter walk test (10MWT), and motor evoked potentials (MEP) were used to evaluate the efficacy before and after 2 weeks of treatment.The SPSS 25.0 software was used for statistical analysis. Independent sample t-test was used for comparison between the two groups, and paired sample t-test was used for comparison before and after treatment within group. Results:Before treatment, there were no statistically significant difference in TUGT time, 10MWT speed and MEP amplitude between the two groups( t=0.659, 0.514, 0.345, all P>0.05).After treatment, the TUGT time((7.87±1.74) s vs (9.31±1.57)s)and MEP amplitude((41.59±14.81)mV vs (58.26±19.26) mV)of the observation group were lower than those of the control group( t=2.723, 3.039, P=0.010, 0.004), while the 10MWT speed of the observation group was higher than that of the control group ((1.21±0.20) m/s vs (1.01±0.17)m/s, t=3.173, P=0.003).After treatment, the TUGT time and MEP amplitude of patients in the observation group and control group were all lower than before treatment (observation group: t=13.512, 7.126, both P<0.001; control group: t=6.535, 3.094, both P<0.05). The 10MWT speeds of patients in the observation group and control group after treatment were both higher than before treatment ( t=25.665, 6.750, both P<0.001). Conclusion:The combination of central and peripheral dual-target magnetic stimulation may improve the FOG of PD patients, and it is worthy of clinical promotion.

Objective:To compare the survival outcomes in patients of small cell lung cancer (SCLC) with brain-single metastasis and brain with organs-multiple metastasis.Methods:Using the US surveillance, epidemiology and final results database, 5 520 SCLC patients with complete clinical information from 2004 to 2015 were selected. SCLC patients were adjusted, stratified or matched according to the metastasis site after the stratification or matching of the propensity scores, and the lung cancer-specific survival (CSS) rate and overall survival (OS) rate were compared between brain-single metastasis group and brain with organs-multiple metastasis group. In addition, the effects of chemotherapy and radiotherapy in CSS between brain-single metastasis group and brain with organs-multiple metastasis group were compared.Results:Of the 5 520 SCLC patients, 2 658 cases was in the brain-single metastasis group, and 2 862 cases was in brain with organs-multiple metastasis group. After the stratification or matching of the propensity scores, the median survival time in brain-single metastasis group was significantly longer than that in brain with organs-multiple metastasis group (6 months vs. 4 months), and there was statistical difference ( P<0.05). The fatality rate in brain-single metastasis group was significantly lower than that in brain with organs-multiple metastasis group (80.66% vs. 85.96%), and there was statistical difference ( P<0.01). Kaplan-Meier survival curve analysis result showed that the OS rate and CSS rate in brain-single metastasis group were significantly higher than those in brain with organs-multiple metastasis group (14.72% vs. 9.50% and 19.34% vs. 14.04%), and there were statistical differences ( P<0.05). Cox analysis result showed that age, race, T stage, gender, N stage, radiotherapy, chemotherapy, tumor diameter, marriage and metastasis were the influencing factors of CSS rate in SCLC patients with brain metastasis ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that radiotherapy and chemotherapy can significantly improve the CSS rate ( HR = 0.668 and 0.671, 95% CI 0.570 to 0.783 and 0.573 to 0.786, P < 0.01). Conclusions:The survival rate in SCLC patients with brain-single metastasis is higher than that of SCLC patients with brain with organs-multiple metastasis; chemotherapy and radiotherapy can improve the survival rate in SCLC patients with brain metastasis.

Objective:To explore the clinical significance of prealbumin(PA) and γ-glutamyltranspeptidase (γ-GT) detection in evaluation of hyperbilirubinemia in neonates at different stages.Methods:From August 2017 to August 2018, 300 full-term delivery patients with neonatal hyperbilirubinemia were selected, including 210 early-stage neonates and 90 late-stage neonates.According to the severity of bilirubinemia, the patients were classified into mild group (50 cases), moderate group (150 cases), and severe group (100 cases). The blood levels of PA and γ-GT of each group were detected.Results:The levels of PA and γ-GT in late neonates were (95.81±4.58)mg/L, (44.97±5.21)IU/L, respectively, which were significantly higher than those in early neonates [(94.77±6.32)mg/L, (53.88±6.32)IU/L]( t=1.410, 11.767, P=0.160, 0.000). With the increase of bilirubin level, the blood PA level was gradually decreased( P<0.05). The blood γ-GT level of moderate and severe patients were significantly higher than that of mild ones ( t=2.222, 2.020, P=0.027, 0.046). The blood levels of γ-GT and PA had no statistically significant differences between moderate patients and severe patients ( t=0.712, 1.741; P=0.477, 0.083). The blood PA level of moderate and severe patients were significantly lower than that of mild patients ( t=2.357, 3.277, P=0.019, 0.001). The serum PA levels had no statistically significant difference between severe patients and moderate patients ( t=0.719, P=0.474); and the serum PA levels of severe and moderate patients were lower than that of mild patients ( t=3.234, 2.117, P=0.001, 0.043). The serum γ-GT levels among the three groups had no statistically significant differences (severe vs.moderate: t=0.297, P=0.767; severe vs.mild: t=0.269, P=0.788; moderate vs.mild: t=0.013, P=0.989). Conclusion:By detecting the levels of PA and γ-GT in neonatal hyperbilirubinemia in different periods, it can provide a reference for clinical judgment of the condition of the children, thus guiding clinical rational treatment.

Objective:To observe the diagnosis effect about the MRI and CT examination for the patients with lacunar cerebral infarction(LAC).Methods: 82 cases early LAC patients during April 2014- June 2016 were diagnosed by two methods, MRI and CT, respectively. And the application effect of the two methods were compared based on image result.Results: In 82 cases of LAC 742 lesions confirmed by MRI and only 145 lesions confirmed by CT, and there was statistical significant between the two methods; especially in front lobe and thalamic, lesions detection rate using MRI was higher than CT, and there was statistical significant between the two methods(x2=6.59,x2=5.64,x2=6.42;P<0.05); the difference of detection rate in capsula internal also was statistical significant(x2=7.43,P<0.05); the number of lesion diameter less than 5mm was 256 using MRI and it was 3 using CT, the difference also was statistical significant(x2=6.39,P<0.05).However, in parietal lobe, basal ganglia and brainstem, all of the difference were not statistical significant (x2=0.18,x2=1.25,x2=0.81;P>0.05);Conclusion: Both of CT and MRI can be used in early diagnosis of LAC, and MRI examination is more accurate for early or micro lesions and lesions happened in the frontal lobe, thalamus, capsula internal than CT. Therefore, MRI can be used as first choice eximination method in early diagnosis of LAC.

Objective To observe the differences in functional capacities generated by different simple breathing balloons extruded by different hand types and methods.Methods The lung functional measurement instrument was used to measure the generated functional capacities of two types of simple breathing balloon extruded by different hand methods: using big-, mid- and small-size hands with 5 fingers generally separately open and maximally extended states or with both small-size hands to extrude balloon; the effective generated gas quantity of the above methods were compared.Results ① Comparison between different balloons: the functional capacity generated by black rubber balloon extruded by any hand type was 68 - 132 mL lower than that generated by light blue silicon balloon. ② The comparison between different hand types: the functional capacities generated by any hand at maximally extended state in extruding balloon was 13 - 70 mL higher than that by hand commonly separate state; extrusion by a small size hand was nearly unable to reach 400 mL, while the functional capacity was 520 - 650 mL when the balloon was extruded by a big size hand, and 435 - 635 mL by a mid-size hand; it was necessary to use both small hands when the black rubber balloon was extruded, when the light blue silicon air bag was extruded, the functional capacity could reach 430 - 440 mL with a small size hand. ③ Difference in extruding methods: the functional capacity generated by either big size hand or mid-size hand with 5 fingers maximally extending state to extrude balloon was significantly higher than that with 5 fingers commonly separate state, the functional capacity generated by both small size hands with fingers maximally separating and extending state to extrude balloon was obviously higher than that generated by 5 fingers generally separating and extending state, the functional capacities generated by light blue silicon balloon were obviously higher than those by black rubber balloon, no matter the 5 fingers of big- or mid-size hand being at generally separating or extending state (mL: 623.00±21.11 vs. 522.00±41.85 by big size hand with common 5 fingers separate state, 649.00±26.01 vs. 575.00±58.55 by big sizehand with maximum 5 fingers extending state; 566.00±37.77 vs. 436.00±21.19 by mid-size hand with common 5 fingers separate state, 637.00±30.02 vs. 505.00±37.49 by mid-size hand with maximum 5 fingers extending state); the light blue silicon balloon extruded by small hand with 5 fingers at generally separate state and at maximally extending state could generate functional capacities (mL)432.00±13.02 and 444.00±37.18 respectively, significantly higher than those using the 2 types of hand state extruding a black rubber balloon (the tidal volume < 400 mL), the functional capacities generated by both small hands extruding a light blue silicon balloon was obviously higher than that by using a black rubber balloon (mL: 557.00±54.98 vs. 489.00±40.12, allP < 0.05).Conclusions Different functional capacities will be generated by different hand sizes, different hand extruding methods and types of simple breathing balloon, clinical application should be based on patients' body weights to decide their tidal volumes, and combined with the rescuers' hand sizes and types of simple breathing balloon to choose a proper extruding method for a certain patient, thus sufficient oxygen can be surely provided in time for him/her and rescue successful rate can be elevated.

OBJECTIVETo explore beryllium oxide induced oxidative lung injury and the protective effects of LBP.

METHODSIntoxication of animals were induced by once intratracheal injection and LBP intervention by intragastric administration. The content of HIF-1, VEGF and HO-1 of lung tissues were measured by kits. The pathological changes of lung tissue were showed by pathological section. The changes of lung ultrastructure were observed by electron microscope.

RESULTSPathological changes of the lung tissue in beryllium oxide exposure group rats were in line with the characteristics of beryllium disease in human. Compared with the control group, HO-1 was increased in beryllium oxide exposure 40 d group and low doses of LBP group, compared with the control group, HO-1 was increased in beryllium oxide exposure 80d group and LBP treatment groups (P < 0.05 or P < 0.01). Compared with the control group, HIF-1 was increased in beryllium oxide exposure 40 d group, LBP treatment groups, beryllium oxide exposure 60 d and 80 d groups (P < 0.05 or P < 0.01). Compared with the control group, VEGF was increased of all phases, especially in beryllium oxide exposure 40d and 80 groups, LBP treatment groups and beryllium oxide exposure 60 d (P < 0.05 or P < 0.01). The content of HO-1 of beryllium oxide exposure group was higher than the LBP treatment for 40d group but below LBP treatment for 80 d group (P < 0.05). The content of HIF1 of beryllium oxide exposure group was higher than high dose of LBP treatment for 60d group and LBP treatment for 80 d group (P < 0.01). The content of VEGF of beryllium oxide exposure group was higher than LBP treatment for 40 d group and high dose of LBP treatment for 60 d (P < 0.05 or P < 0.01).

CONCLUSIONSBeO can cause abnormal expression of related genes of lung tissue in rats, LBP has protective effects on BeO caused lung injury.
