RESUMO
Objective:To observe the clinical effectiveness of manual therapy based on posture decoding for patients with lower crossed syndrome (LCS).Methods:Thirty-six LCS patients were randomly divided into an observation group and a control group, each of 18. The observation group received manual therapy based on posture decoding, while the control group was treated with proprioceptive neuromuscular facilitation (PNF), both in 20min sessions, once a week for 4 weeks. Before the experiment, after one, two and four weeks of treatment and followed-up 4 and 8 weeks later, both groups were evaluated using a visual analogue scale (VAS), the Oswestry Disability Index (ODI) and finger-floor distance (FFD). Anterior pelvic tilt angles (ASIS-PSISs), sacral slopes (SS), lumbar curve index (LCI) and surface EMG flexion-relaxation ratios (FRRs) were also recorded from both groups before and after the treatment.Results:After one and four weeks of the treatment, the average VAS, ODI, and FFD had decreased significantly in both groups, with all significantly lower in the observation group, on average. At the final follow-up, the average VAS and ODI scores of both groups were significantly lower than before the treatment, with those of the observation group significantly lower than the control group′s averages. After 4 weeks of treatment significant differences were observed also in the group′s average ASIS-PSISs, SSs and LCIs compared with before the treatment. And right after the treatment the left and right surface electromyography FRRs of the observation group were significantly higher than those of the control group.Conclusion:Manual therapy based on posture decoding can significantly improve the pelvis forward angle and lumbar motion of LCS patients, relieving back pain and relaxing back muscles.

Objective:To observe the clinical effect of spinal manipulation on chronic, non-specific neck pain.Methods:Thirty patients with chronic, nonspecific neck pain were divided randomly into an observation group ( n=15) and a control group ( n=15). Patients in the observation group were given 20 minutes of a novel 4R spinal manipulation (resetting joint malalignment, resetting abnormal muscle, resetting joint stabiliazation, resetting sensorimotor control) twice a week for 2 weeks while the control group were given 20 minutes of medium frequency and high frequency conventional physiotherapy 4 times a week, also for 2 weeks. Before the treatment, right after, and one and three months later, both groups were evaluated using a visual analogue scale (VAS) and a neck disability index (NDI). Right before and after the treatment, cervical flexion and extension range of motion (ROM) were measured. The surface electromyography was employed to record the root mean square (RMS) of the EMG amplitude and the median frequency (MF) from the erector spinae and upper trapezius. Results:Before the treatment no significant differences were found in any of the measurements between the two groups. Afterward and one and three months later the average VAS, NDI and cervical ROM results of both groups had improved significantly, with the improvements in the observation group significantly greater than those in the control group on average. After 2 weeks of treatment, the average RMS and MF values had improved in both groups, again with the observation group′s average values significantly better than those of the control group.Conclusion:Spinal manipulation can effectively improve the strength and stamina of cervical muscle groups in patients with chronic, non-specific neck pain.
RESUMO
BACKGROUND@#The aim of this study is to investigate the changes of peripheral blood lymphocyte subsets before and after treatment with pembrolizumab for non-small cell lung cancer and its clinical significance.@*METHODS@#A total of 32 patients with non-small cell lung cancer who received pembrolizumab treatment in The Affiliated Hospital of Qingdao University and Weifang People's Hospital of Shandong Province from January 2015 to December 2020 were selected as the observation group, and 30 healthy people during the same period were selected as the control group. Before treatment and in cycles 1, 2 and 4 after treatment, fluid cytometry was used to detect changes in the levels of lymphocyte subsets in the peripheral blood of patients.@*RESULTS@#The CD3⁺, CD4⁺, CD4⁺/CD8⁺ indexes of patients with non-small cell lung cancer before the treatment were significantly lower than those in the control group (P0.05), and the CD8⁺ index was slightly lower than before the treatment (P0.05). At the same time, this article shows through analysis that the expression of programmed cell death ligand 1 (PD-L1) and pathological types have no obvious influence on the effect of immunotherapy. Multi-factor analysis shows that it is more meaningful to observe the changes of CD3⁺, CD4⁺ and CD8⁺ at the same time to predict the effect of immunotherapy.@*CONCLUSIONS@#Pembrolizumab can regulate the changes of T lymphocyte subsets in patients with non-small cell lung cancer, improve the immune status of the patients, and there is no obvious adverse reaction. At the same time, monitoring the changes of lymphocyte subsets during treatment can predict the effect of immunotherapy.
RESUMO
Lung cancer is the malignant tumor with the highest incidence in China. Early detection and identification of symptomatic lung cancer patients and timely screen out asymptomatic patients from high-risk groups require multiple cooperation. At present, although combined imaging, serology, genomics, proteomics and other methods have been combined to screen for suspected lung cancer, there are still problems such as missed diagnosis and misdiagnosis. Meanwhile, the spread of the corona virus disease 2019 (COVID-19) epidemic has brought new challenges to early lung cancer screening. Under the normalization of epidemic prevention and control, the work of early lung cancer screening should be changed accordingly: improve the population's awareness of cancer prevention and control, strengthen the management of medical procedures, improve the efficiency of tumor detection, optimize detection technology, and utilize internet and big data platforms rationally. We should establish an ideal model, combining multiple screening methods, which is streamlined and efficient for early lung cancer screening under normal epidemic prevention and control. .

Objective:To observe the effect of contralateral controlled functional electrical stimulation (CCFES) on the recovery of upper limb motor function after a stroke.Methods:Stroke survivors 1 to 6 months after onset were randomly divided into a CCFES group (14 cases, group A), a CCFES intensive group (14 cases, group B) and a neuromuscular electrical stimulation group (15 cases , group C). In addition to routine rehabilitation training, groups A and B received contralateral controlled functional electrical stimulation, while Group C received routine neuromuscular electrical stimulation. Group B was treated twice daily, while the other two groups were given 1 session each day, 5 times a week for 3 weeks. Each session lasted 20 minutes. The Fugl-Meyer assessment (FMA), the Modified Barthel Index (MBI), surface electromyography and the active range of motion for wrist dorsiflexion were used to evaluate the subjects′ upper limb function before and after the treatment.Results:There was no significant difference in any of the measurements among the three groups before the treatment. After the treatment, all of them had improved significantly, with the improvements in groups A and B significantly greater than in group C, on average.Conclusions:Both normal and intensive contralateral controlled functional electrical stimulation have significant advantages over neuromuscular electrical stimulation in promoting functional recovery of the upper limbs. Intensive CCFES training is superior to routine training in improving muscle strength and range of motion.
RESUMO
Objective To investigate the effects of treadmill training at different intensities on neurological function and expression of kalirin-7 in rats after cerebral ischemia-reperfusion,and the possible mechanism.Methods Sixty Wistar male rats were randomized into a model group,a routine training group,an intensive training group and a sham-operation group (n =15 for each group).A middle cerebral artery occlusion/reperfusion (MCAO/R) model was established in all the rats of the first three groups.The model group and sham group did no motor training,while the utine training group did treadmill training once daily,and the intensive training group did treadmill training twice a day.On the 3rd,7th and 14th day,Zausinger scores was used to evaluate the neurological deficit;reverse Transcription PCR (RT-PCR) and Western blot were adopted to detect the expression of kalirin-7 and kalirin-7 mRNA in the peri-ischemic brain tissues respectively.Results The average Zausinger scores of the model group and 2 training groups were significantly lower than that of the sham-operation group at all time points;on the 7th and 14th days,the average score of the intensive training group was significantly higher than that of the outine training group.Moreover,the expression of kalirin-7 and kalirin-7 mRNA in the MCAO rats were significantly lower than that in the sham-operation group.On days 7 and 14,the expression of kalirin-7 in the intensive training group was significantly higher than that of the routine training group,which was still significantly higher than the model group.On day 14,the expression of kalirin-7 mRNA in the intensive training group was significantly higher than that of the routine training group,which was still significantly higher than the model group.Conclusion The intensive training is superior to routine training in promoting neural functional recovery and expression of kalirin-7 in rats with cerebral ischemia-reperfusion.

Objective To observe the effects of intensive-swimming training at different intensities on the neurological function and the expressions of protein kinase A after cerebral ischemia-reperfusion in rats,and to explore the possible neuroprotection mechanism of intensive-swimming training after cerebral ischemia-reperfusion in rats.Methods The animal model of cerebral ischemia-reperfusion was established in rats by using the intraluminal thread method to cause left middle cerebral artery occlusion (MCAO) for 2 h and then reperfusion.A total of 120 male model Sprague-Dawley rats were randomly divided into training group 1 (swimming for 5 min once a day),training group 2 (swimming for 10 min once a day),training group 3 (swimming for 20 min once a day) and control group (no training),with 30 rats in each group.Another 30 rats who were assigned to the sham-operation group were subject to no MCAO and no training.At the 3rd,7th and 14th day post operation,10 rats randomly selected from each group were examined for their neurological function by Menzies neurobehavioral test and forelimb placing test.Expressions of protein kinase A were detected by immunohistochemistry method.Expressions of PKA-mRNA were detected by using RT-PCR.Results The neurological function in sham-operation group was normal.The differences between sham-operation group and control group with regard to Menzies test and forelimb placing test scores were statistically significant at all the time points (P ＜ 0.05).The improvement of neurological function in all training groups,were significantly better than those in controls at the 3rd,7th and 14th d after swimming training,especially in training group 3 on the 14th day post-operation (P ＜0.05).At3rd,7th,and 14th days post-operation,the Menziesscores were(1.40±0.55),(1.00 ±0.71)and (0.80 ±0.45),respectively,and the forelimb placing scores were(5.20 ± 0.84),(3.80 ± 1.30) and (2.40 ± 1.14),respectively,in the training group 3.The number of positive cells and the expressions of protein kinase A mRNA were significantly higher in all training groups than those in the controls at the 3rd,7th and 14th days after swimming training,and the increase of positive cells and mRNA of PKA in the training group 3 was significantly more obvious at 14th day compared with other training groups(P ＜ 0.05).Conclusions Exercise training can increase the expression of positive cells and mRNA of PKA in rats after cerebral ischemiareperfusion,hence,it improved the injured neurological function and promote the recover of sensory and motor function,and the more intensive the training,the better the effects.
