ABSTRACT

OBJECTIVE To re-eval uate the systematic review and meta-an alysis of umeclidinium bromide and vilanterol trifenatate(UMEC/VIL)in the treatment of chronic obstructive pulmonary disease (COPD),so as to provide evidence-based basis for the treatment of COPD. METHODS Retrieved from PubMed (Medline),the Cochrane library ,Embase,CNKI,CBM,VIP and Wanfang database ,etc.,the systematic review and meta-analysis of UMEC/VIL in the treatment of COPD were collected from the inception to Apr. 2021. Two reviewers independently screened the literatures and extracted the data. AMSTAR 2 scale,PRISMA statement,and GRADE evaluation system were used to evaluate the methodological quality of the included studies ,the quality of reports and the grade of outcome indexes. The efficacy and safety of UMEC/VIL in the treatment of COPD were reported. RESULTS Six systematic reviews were finally included. The results of AMSTAR 2 scale showed that 1 study was of high quality , 2 were of medium quality and 3 were of low quality. The score of PRISMA statement was between 21.5 and 27,and the quality of the report was relatively perfect. The results of GRADE evaluation showed that more than 60% of the 134 outcome indicators were of medium to high quality of evidence. Comparison of effectiveness and safety showed that UMEC/VIL was superior to placebo , unilateral bronchodilator and salmeterol fluticasone in improving forced expiratory volume in one second (FEV1)trough,FEV1 peak and forced vital capacity (FVC). In the improvement of transition dyspnea index (TDI),SGRQ and SOBDA scores ,UMEC/ VIL was better than placebo ,unilateral bronchodilator and fluticasone propionate/salme terol. The adverse reaction rate ,acute exacerbation rate ,mortality rate ,withdrawal rate ,pneumonia rate and other negative indicators of UMEC/VIL were not inferior to placebo,unilateral bronchodilator and fluticasone propionate/salme terol. CONCLUSIONS Compared with placebo and unilateral bronchodilator,UMEC/VIL can significantly improve lung function ,symptoms and quality of life ,and has non-inferior effect for negative indicators. Compared with β2 adrenoceptor agonists combined with glucocorticoid ,UMEC/VIL can improve lung function of COPD patients ,but they are similar in other aspects.

ABSTRACT

Objective:To explore the influence of symptom group of stroke patients with exercise disorder on acute stress disorder.Methods:Patients with stroke and motor impairment hospitalized in the Department of Neurology and surgery of North China University of technology from October 2018 to August 2019 were selected as the research objects.The general information of patients, brain injury subscale (BIS) and Stanford acute stress reaction questionnaire (SARSQ) were investigated by questionnaire.Results:A total of 324 patients with stroke and motor disorders were investigated.The demographic characteristics of education, age, degree of motor function, number of combined dysfunction and Activity Of Daily Living Scale(ADL) grade had effects on acute stress disorder, and the differences were statistically significant( P<0.05). The score of acute stress disorder in stroke patients with motor disorders was (99.60±13.69 ) points.From the highest to the lowest symptom group, the scores were obsessive symptom (11.35±2.71), depression (7.44±1.86), hostility (7.23±2.26), somatization (3.69±1.42) and psychosis (2.81±1.09). The results of correlation analysis showed that somatization, depression, obsessiveness, hostility and psychosis were positively correlated with the total score of acute stress disorder and the scores of each dimension ( r=0.164, 0.355, 0.329, 0.298, 0.279, all P<0.05), the symptoms were also positively correlated with all the dimensions of acute stress disorder(all P<0.05). Multiple linear regression analysis showed that age(Regression coefficient=7.682, 95% CI: 4.930-10.435, P<0.001), the number of combined dysfunction(Regression coefficient=3.937, 95% CI: 0.268-7.605, P=0.036), depression(Regression coefficient=1.662, 95% CI: 0.727-2.597, P=0.001) had influence on ASD of stroke patients. Conclusion:The level of acute stress disorder in stroke patients with motor impairment is on the high side, and the characteristics of symptom group are obvious, which has a positive correlation with acute stress disorder.Medical staff should pay attention to the characteristics of symptom group and acute stress reaction level of stroke patients with motor impairment, so as to provide targeted intervention strategies to avoid disease recurrence and improve the quality of life.

ABSTRACT

Objective:To study the effect of Wenjing Huayu Zhitong therapy (Xiangyan Zhitong prescription, XZP) on the mitogen activated protein kinase (MAPK)/extracelluar regulated protein kinase (ERK) signaling pathway of primary dysmenorrhea (PD) rats, and explore the pathogenesis of PD and the mechanism of action of Wenjing Huayu Zhitong therapy. Method:Forty-eight female SPF-grade Wistar rats were randomly divided into blank group,model group, western medicine group, low-dose XZP group, medium-dose XZP group, and high-dose XZP group, with 8 rats in each group. In addition to the blank group, dysmenorrhea rat model with cold coagulation and blood stasis syndrome was established by cold stimulation combined with estradiol benzoate and oxytocin. The rats in the blank group,model group,western medicine group, low-dose XZP group, medium-dose XZP group, and high-dose XZP group were given distilled water, distilled water,0.06 g·kg<sup>-1</sup> ibuprofen, 6.55 g·kg<sup>-1</sup> XZP, 13.09 g·kg<sup>-1</sup> XZP, and 26.18 g·kg<sup>-1</sup> XZP, respectively, by gavage for 6 days. The writhing latency and writhing frequency of rats were recorded within 30 min after oxytocin injection.Western blot was used to detect the protein expression of B-Raf, mitogen activates extracellular regulated kinases1/2 (MEK1/2), extracellular regulated kinases1/2 (ERK1/2), p-MEK1/2, p-ERK1/2, c-Jun, and cyclooxygenase-2 (COX-2) in rat uterus. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to detect the mRNA expression of B-Raf, MEK1, MEK2, ERK1, ERK2, c-Jun, and cyclooxygenase-2 (COX-2) in rat uterus. Result:Compared with the model group,the treatment groups showed insignificantly prolonged writhing latency and significantly reduced writhing frequency (<italic>P</italic><0.01). On the 6<sup>th</sup> day of modeling, there was no significant difference in the quantitative scores of symptoms and signs among the treatment groups. On the 12<sup>th</sup> day of modeling, the scores changed little in the western medicine group and the low-dose XZP group and decreased significantly in the medium- and high-dose XZP groups (<italic>P</italic><0.01) compared with those in the model group. Compared with those in the blank group, the protein and mRNA levels of p-MEK1/2, p-ERK, B-Raf, c-Jun, and COX-2 in the model group were significantly up-regulated (<italic>P</italic><0.01). Compared with those in the model group, the protein and mRNA levels of p-MEK1/2, p-ERK1/2, B-Raf, c-Jun, and COX-2 in the western medicine group, medium-dose XZP group, and high-dose XZP group were significantly down-regulated (<italic>P</italic><0.05,<italic>P</italic><0.01). Conclusion:The mechanism of Wenjing Huayu Zhitong therapy in treating PD with cold coagulation and blood stasis syndrome may be related to the down-regulation of MAPK/ERK signaling pathway.

ABSTRACT

Objective:To carry out germplasm resource evaluation and new variety breeding of <italic>Murraya paniculata</italic> and improve the germplasm quality, so as to ensure the demand, yield and quality of medicinal materials. Method:Following resource investigation and collection, 17 traits of 107 <italic>M. paniculata</italic> germplasm samples, like plant type, basal diameter, leaf shape, leaf length, and leaf width were determined and then subjected to principal component analysis and factor analysis for screening the principal component factors. Nine primary traits were selected as variables for further cluster analysis using Ward's method and Euclidean distance. According to the characteristics of medicinal parts, the core germplasms were screened out. Then the contents of auxin, zeatin, zeatin nucleoside, isopentenyl adenine, isopentenyl adenine riboside, dihydrozeatin, and dihydrozeatinriboside in the leaves were measured by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), followed by their correlation analysis with agronomic trait. Result:The variation coefficients of petiole length, branching number, and basal diameter were large. The nine main factors could be classified into four categories, with a contribution rate of 72.822%. The cluster analysis with Ward's method and Euclidean distance showed that 107 germplasm samples were clustered into six clusters and 61 core germplasms were identified. Such traits as leaf length, leaf width, petiole length, leaf surface, and petiole color were found to play an important role in the classification of <italic>M. paniculata</italic> germplasms. The content of zeatin nucleoside exhibited significant positive correlations with leaf length (<italic>P</italic><0.01), petiole length (<italic>P</italic><0.01), and leaf width (<italic>P</italic><0.05). Conclusion:These results have laid the foundation for further selection and breeding of <italic>M. paniculata</italic> new varieties.

ABSTRACT

The present study was aimed to observe the characteristics of sublingual microcirculation and the changes of humoral factors in healthy people of three different high altitude populations. Three groups of healthy subjects in Guoluo area of Qinghai province (4 100 m) were included: Tibetan group: 30 Tibetans, (45.62 ± 10.15) years old; Han group: 22 two-generation of Han immigrants, (46.23 ± 8.59) years old; migrant group: 23 migrants living at high altitude for 2-5 years, (43.45 ± 8.31) years old. Blood routine test was performed to determine white blood cell (WBC) count, red blood cell (RBC) count, hemoglobin (HGB), hematocrit (HCT), platelet (PLT) count, and neutrophil (NEUT) count. The changes of serum humoral factors including endothelin-1 (ET-1), CD31, CD34, CD105, vascular endothelial growth factor (VEGF), nitric oxide (NO) and noradrenaline (NE) were detected by ELISA. Continuous noninvasive hemodynamics monitor was used to continuously measure the changes of systemic circulation indexes: cardiac output (CO), cardiac index (CI), heart rate (HR), stroke volume (SV), pulse pressure variation (PPV), systemic vascular resistance index (SVRI), and mean arterial pressure (MAP). Blood oxygen was measured by pulse oximeter. Sublingual microcirculation indexes including total vascular density (TVD), perfused vessel density (PVD), proportion of perfused vessels (PPV), and microvascular flow index (MFI) were determined by sidestream dark field imaging. The results showed that there were no difference in systemic circulation among the 3 groups. Compared with Tibetan group, TVD and PVD of microcirculation in Han group and migrant group were significantly increased (P < 0.05). Compared with Tibetan group and Han group, WBC, RBC, HGB and HCT of migrant group were significantly increased (P < 0.05). Compared with Han group and Migrant group, PLT of Tibetan group was significantly increased (P < 0.05). Compared with the Tibetan group, the levels of serum humoral factors CD105 and VEGF were significantly higher in the migrant group (P < 0.05), while compared with Han and migration groups, NO in Tibetan group was significantly increased (P < 0.05). It is suggested that there were significant differences in microcirculation (TVD, PVD), blood routine (WBC, RBC, HGB, HCT) and humoral factors (CD105, VEGF) among different populations in high altitude area. Importantly, the increased microcirculation, erythrocytosis and increased pro-angiogenic factors due to hypoxic environment were observed in long-term residents and migrants, except for permanent residents. These physiological changes have clinical significance in the treatment of septic shock and chronic altitude sickness for different plateau populations.

ABSTRACT

Objective:To investigate the expression of urinary exosomal miR-150-5p in different age groups and its relationship with kidney aging.Methods:Seventy-six subjects were recruited at the geriatrics department of Beijing Friendship Hospital from January 2014 to December 2016, with 15 in the young group, 35 in the middle-aged group, and 26 in the elderly group.We detected the expression of urinary exosomal miR-150-5p by real-time PCR from urine samples of different age groups and used Logistic regression analysis to evaluate the correlation of different levels of miR-150-5p with age, gender, history of hypertension, history of coronary heart disease, and hyperlipidemia.Additionally after overexpression and knockdown of miR-150-5p in human renal tubular cells of the HK2 cell line, we analyzed the expression levels of epithelial-to-mesenchymal transition(EMT)-related proteins by Western blotting.Results:Logistic regression analysis showed that age was closely related to estimated urinary exosomal miR-150-5p levels( P<0.05), and estimated urinary exosomal miR-150-5p levels in the elderly group(1.33±0.41)were significantly higher than those in the young group(0.88±0.40)( P<0.05). In addition, estimated urinary exosomal miR-150-5p levels became inversely proportional to the glomerular filtration rate as age increased. In vitro experiments showed that the expression levels of ZO-1 and E-cadherin in epithelial cells were slightly decreased after knockdown of miR-150-5p in renal tubular epithelial cells of the HK-2 cell line. Conclusions:The expression of miR-150-5p in urinary exosomes may be slightly increased in the elderly.It could inhibit the occurrence of renal EMT, and its expression is correlated with renal function.Mir-150-5p may also affect the expression of adhesion molecule-related proteins in HK-2 cells.MiR-150-5p in urinary exosomes is expected to become one of the genetic markers associated with renal aging.

ABSTRACT

OBJECTIVE@#To analyze the relationship between the expression level of SQLE and the prognosis of patients with acute myeloid leukemia (AML) through large sample data.@*METHODS@#The data of genome, transcriptome, gene chip expression, and clinical information were statistically analyzed in multiple cohorts of AML patients with large samples.@*RESULTS@#It was found that the expression level of SQLE gene in tumor cells of AML patients was significantly higher than that of healthy controls (P=0.001). In the three AML corhort, the SQLE high expression group showed a worse therapeutic outcome (OS, P=0.009, P=0.0001, P=0.006; EFS, P=0.005, P=0.001). The unvariate and multivariate survival prognosis analysis indicated that the high expression of SQLE suggests lower event-free survival rate (EFS, HR=1.551, P<0.05) and overall survival rate (OS, HR=1.484, P<0.05). At the same time, it was also found that among different risk subgroups, the expression of SQLE in high risk group was higher (P<0.001, P=0.01), while the patients with high SQLE expression, who received allogeneic HSCT, had longer overall survival time (P=0.006).@*CONCLUSION@#The up-regulation SQLE expression suggests a poor prognosis for the patients with AML.

ABSTRACT

Objective To evaluate the clinical efficacy of percutaneous transluminal angioplasty (PTA) combined with stent implantation in the treatment of transplant renal artery stenosis (TRAS) after renal transplantation. Methods Clinical data of 21 patients with TRAS after renal transplantation undergoing PTA combined with stent implantation were retrospectively analyzed. The incidence of TRAS in renal transplant recipients was summarized. The changes of relevant indexes in patients with TRAS were statistically compared before and after interventional treatment. Clinical prognosis of patients with TRAS was evaluated. Results The incidence of TRAS in renal transplant recipients was 4.1%(21/507). TRAS was diagnosed at postoperative 5 (4, 7) months, and 67% (14/21) of patients developed TRAS within postoperative 6 months. Compared with the values before interventional therapy, the serum creatinine level, systolic and diastolic blood pressure and peak flow velocity of transplant renal artery of patients with TRAS were significantly decreased, and the estimated glomerular filtration rate (eGFR) and interlobar arterial resistance index were significantly increased at 1 week and 1 month after interventional therapy (all P < 0.05). During postoperative follow-up after PTA combined with stent implantation, 1 patient suffered re-stenosis of the transplant renal artery, which was improved after simple balloon dilatation. One patient developed pseudoaneurysm formation at the puncture site of the right femoral artery. One patient presented with renal atrophy and loss of function due to atresia of the transplant renal artery. All the remaining 18 patients were well recovered after surgery. Conclusions PTA combined with stent implantation is the optimal treatment of TRAS after renal transplantation, which can significantly improve the function of transplant kidney and considerably prolong the survival time of transplant kidney.

ABSTRACT

There are two source plants for the traditional Chinese medicine Murrayae Folium et Cacumen (MFC) in Chinese Pharmacopoeia, i.e. Murraya exotica L. and M. paniculata (L.) Jack. Herein, a chemical comparison of M. exotica and M. paniculata by high performance liquid chromatography (HPLC) fingerprint analysis coupled with chemometrics and network pharmacology was performed. The main peaks in the fingerprints were identified by liquid chromatography coupled with ion trap/time-of-flight mass spectrometry (LC-IT-TOF-MS) and authenticated by references. The chemometrics results showed that the HPLC fingerprints of these two species were clearly divided into two categories using hierarchical cluster analysis (HCA) and principal component analysis (PCA), and a total of 13 significantly differentiated markers were screened out by orthogonal partial least squares-discriminant analysis (OPLS-DA). However, the following network pharmacology analysis showed that these discriminated markers were found to act via many common targets and metabolic pathways, indicating the possibly similar pharmacological effects and mechanisms for M. exotica and M. paniculata. The above results provide valuable evidence for the equivalent use of these two plants in clinical settings. Moreover, the chromatographic fingerprint analysis coupled with chemometrics and network pharmacology supplies an efficient approach for the comparative analysis of multi-source TCMs like MFC.

ABSTRACT

Objective:To explore the effects of different doses of Ethephon on testes of male pups.Methods:Thirty-two 45-day-old healthy female Sprague-Dawley (SD) rats were randomly divided into the control group and the low dose, middle dose and high dose Ethephon groups by the random figure table.The female rats in the low dose, middle dose and high dose Ethephon groups were given 200, 400, and 800 mg/kg Ethephon solution, respectively.The control group was treated with 9 g/L saline.After the birth of the offspring, the mother rats were not administrated with any medications, and the male offspring rats were given Ethephon solution instead.Twelve offspring male rats were randomly selected from each group and killed at the age of 0, 14 and 28 days after birth.Fresh testicular tissues were stained with hematoxylin eosin (HE), and the morphological changes of testicular tissues were observed under light microscope.The apoptotic cells were labeled by terminal dexynucleotidyl transferase (TdT) mediated dUTP nick end labeling (TUNEL) method and the apoptosis index (AI) of spermatogenic cells was detected by fluorescence microscope.Results:(1) Compared with the newborn rats in the middle dose group, low dose group and control group, se-miniferous tubules in the newborn rats of the high dose group were slightly thicker, and seminiferous cells were arranged slightly in disorder.The AI of the newborn rats in high dose group was significantly higher than that in the control group (1.00±0.06 vs.0.41±0.03, P<0.01). The AI of the newborn rats in the middle dose group was not significantly different from that in the control group and the low dose group ( P>0.05). (2) The seminiferous tubules of the 14-day-old rats in the low dose, middle dose and high dose Ethephon groups were significantly thicker and arranged more loosely than those in the control group.Compared with the control group, there were very few seminiferous cells, which were arranged disorderly in the low dose, middle dose and high dose Ethephon groups.The AI of the 14-day-old rats in the low dose, middle dose and high dose Ethephon groups was (2.13±0.10), (2.18±0.10) and (3.90±0.23), respectively, which were significantly higher than that in the control group (1.00±0.02) ( F=2 508.36, P<0.01). There was no significant difference in the AI between the middle dose and low dose groups ( P>0.05). (3) Compared with the control group, the seminiferous tubules of the 28-day-old rats in the low dose, middle dose and high dose groups were significantly thicker and arranged much more loosely, and spermatogenic cells were even less and arranged in a severely disordered way.The AI of 28-day-old rats in the low dose group (5.52±0.13), the middle dose group (9.44±0.07) and the high dose group (14.56±0.27) was significantly higher than that in the control group (3.11±0.13) ( F=10 784.69, P<0.01). Conclusions:Ethephon can thicken the seminiferous tubules of newborn and young rats, cause the germ cells to arrange disorderly, promote the apoptosis of spermatogenic cells and reduce the ability of spermatogenesis.Moreover, a longer exposure of the rats to a higher concentration of Ethephon will result in more serious damage to testicular tissues.

ABSTRACT

In the current study, we sought to investigate whether T-type Ca channels (TCCs) in the brain are involved in generating post-anesthetic hyperexcitatory behaviors (PAHBs). We found that younger rat pups (postnatal days 9-11) had a higher incidence of PAHBs and higher PAHB scores than older pups (postnatal days 16-18) during emergence from sevoflurane anesthesia. The power spectrum of the theta oscillations (4 Hz-8 Hz) in the prefrontal cortex was significantly enhanced in younger pups when PAHBs occurred, while there were no significant changes in older pups. Both the power of theta oscillations and the level of PAHBs were significantly reduced by the administration of TCC inhibitors. Moreover, the sensitivity of TCCs in the medial dorsal thalamic nucleus to sevoflurane was found to increase with age by investigating the kinetic properties of TCCs in vitro. TCCs were activated by potentiated GABAergic depolarization with a sub-anesthetic dose of sevoflurane (1%). These data suggest that (1) TCCs in the brain contribute to the generation of PAHBs and the concomitant electroencephalographic changes; (2) the stronger inhibitory effect of sevoflurane contributes to the lack of PAHBs in older rats; and (3) the contribution of TCCs to PAHBs is not mediated by a direct effect of sevoflurane on TCCs.

ABSTRACT

Objective:To investigate the effects of caspase-11 non-canonical inflammasome on the Leptospira interrogans ( L. interrogans)-induced secretion of inflammatory cytokines in J774A.1 cells. Methods:Murine mononuclear macrophage cells (J774A.1) were infected with L. interrogans strain 56601. Expression of caspase-11, IL-1β, IL-1α and IL-18 at mRNA level in J774A.1 cells were detected by real-time RT-PCR. The levels of caspase-11, IL-1β, IL-1α and IL-18 in the culture supernatants of J774A.1 cells were detected by ELISA. Results:Real-time RT-PCR showed that caspase-11 expression at mRNA level was 5.12, 14.21, 8.94, 14.06, 18.58 and 0.93 times of that in uninfected cells after 1, 2, 4, 8, 12 and 24 h of L. interrogans infection, and respectively decreased to 0.10, 0.07, 0.10, 0.09, 0.07 and 0.45 times after caspase-11 inhibitor intervention ( P<0.05). Expression of IL-1β, IL-1α and IL-18 at mRNA level was significantly increased after infection ( P<0.05). After the intervention with caspase-11 inhibitor, IL-1β mRNA decreased to 0.05, 0.03, 0.02, 0.05, 0.06 and 0.02 times ( P<0.05); IL-1α mRNA decreased to 0.14, 0.07, 0.15, 0.10, 0.03 and 0.06 times ( P<0.05); IL-18 mRNA decreased to 0.08, 0.10, 0.16, 0.18, 0.10 and 0.07 times ( P<0.05). ELISA results showed that the expression of caspase-11, IL-1β, IL-1α and IL-18 at protein level was significantly increased. After the intervention with caspase-11 inhibitor, caspase-11 level decreased to 43.07, 41.64, 51.96, 86.56, 105.36, and 129.95 pg/ml ( P<0.05); IL-1β level decreased to 15.01, 14.19, 68.02, 31.20, 173.13 and 104.98 pg/ml ( P<0.05); IL-1α level decreased to 12.14, 15.40, 38.01, 21.97, 24.48 and 27.09 pg/ml ( P<0.05); IL-18 level decreased to 96.27, 102.21, 85.34, 116.28, 155.36 and 114.03 pg/ml ( P<0.05). Conclusions:Caspase-11 non-canonical inflammasome was involved in the mediation of IL-1β, IL-1α and IL-18 secretion in mouse mononuclear macrophages after L. interrogans infection.

ABSTRACT

OBJECTIVE@#To explore the efficacy difference of electroacupuncture at lower -sea point and -sea matching front- points for the treatment of gastroparesis.@*METHODS@#A total of 63 patients with gastroparesis were randomly divided into a lower point group (group A, 32 cases, 2 cases dropped off) and a matching points group (group B, 31 cases, 1 case dropped off). The group A was treated with electroacupuncture at Zusanli (ST 36), and the group B was treated with electroacupuncture at Zusanli (ST 36) and Zhongwan (CV 12). Both groups were treated with continuous wave (2 Hz in frequency) for 30 min, once a day, 5 times a week for 3 weeks. The gastroparesis cardinal symptom index (GCSI) score, gastric half-emptying time (T) and the 180 min gastric residual rate of the two groups before and after treatment were observed, and the clinical effective rate was compared.@*RESULTS@#After treatment, the total GCSI scores, T and the 180 min gastric residual rates in both groups were lower than those before treatment (<0.01), and the 180 min gastric residual rate and T in the group A were lower than those in the group B (<0.05). The total effective rate was 93.3% (28/30) in the group A, which was superior to 70.0% (21/30) in the group B (<0.05).@*CONCLUSION@#Electroacupuncture at lower -sea point and -sea matching front- points can both be used to treat gastroparesis, but electroacupuncture at Zusanli (ST 36) has a better effect. The acupoints of Zusanli (ST 36) and Zhongwan (CV 12) may have antagonistic effects.

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.

ABSTRACT

Objective:To observe the clinical effect of low and medium intensity aerobic exercise combined with resistance exercise on patients with chronic kidney disease (CKD) complicated with sarcopenia. Methods:From 2018 to 2019, 11 elderly patients with CKD complicated with sarcopenia were enrolled in this study. All the patients received low and medium intensity aerobic exercise combined with resistance exercise intervention on the basis of regular internal medical treatment. Each exercise section included 30 to 50 minutes of aerobic exercise and 20 to 30 minutes of resistance exercise, and was conducted three times a week for twelve weeks. Before exercise, and 24 hours, six weeks and twelve weeks after exercise, the related indicators were measured. Results:No statistical difference in serum lipids and renal function indicators was found 24 hours after exercise, and six and twelve weeks post exercise (P > 0.05). Compared with pre-exercise condition, the reach in seat increased six weeks after exercise (P < 0.05); the appendicular skeletal muscle mass index, the grip strength index, the 6-meter walking speed, the peak oxygen uptake (VO2peak), the one-leg standing time and the reach in seat improved twelve weeks after exercise (P < 0.05). Compared with the results six weeks after exercise, the grip strength index, the 6-meter walking speed, VO2peak and the one-leg standing time improved twelve weeks after exercise (P < 0.05). Conclusion:Structured exercise training of low and medium intensity aerobic exercise combined with resistance exercise training would not worsen the renal function of patients with CKD complicated with sarcopenia; however, it could improve the muscle mass, strength and motor function of them.

ABSTRACT

OBJECTIVE: To explore the current situation and correlation between the attitude toward seeking professional psychological help and perceived stress in policemen. METHODS: The Attitude Toward Seeking Professional Psychological Help Scale and the Perceived Stress Scale were used to conduct surveys in 240 policemen, who were selected from Sichuan practice training bases by cluster random sampling method.RESULTS: The total scores of the attitude toward seeking professional psychological help and perceived stress in policemen were(94.9±11.9) and(38.6±6.7) respectively. The total score of the attitude toward seeking professional psychological help of rural policemen was higher than that of urban policemen(P<0.05). The total scores of the attitude toward seeking professional psychological help of criminal policemen, security policemen and prison guards were higher than that of logistics policemen(P<0.05). The total score of perceived stress of policemen aged over 40 was higher than those of policemen aged in the 20 s and 30 s(P<0.05). The total score of perceived stress of divorced policemen was higher than those of married and unmarried policemen(P<0.05). The total score of the attitude toward seeking professional psychological help was negatively correlated with the total score of perceived stress(P<0.01). The total score of the attitude toward seeking professional psychological help of policemen in the high risk pressure group was lower than that in the normal pressure group(P<0.05). CONCLUSION: The attitude toward seeking professional psychological help of policemen was at the average level and was negatively correlated with their psychological stress.

ABSTRACT

Objective@#To analyze the risk factors of cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.@*Methods@#530 patients with esophageal cancer underwent thoracoscopic-lapacoscopic esophagectomy at the Cancer Hospital, Chinese Academy of Medical Sciences from Jan 2011 to Dec 2015. The demographic, surgical and clinical data of patients were retrospectively analyzed. Multivariate logistic regression was used to evaluate risk factors of cervical anastomotic leakage in these patients.@*Results@#A total of 530 patients undergoing thoracoscopic-lapacoscopic esophagectomy were enrolled in this study. There were 421 males and 109 females. The mean age was (59.40±8.08) years old, and 91 patients with cervical anastomotic leakage. Sigle factor analysis revealed that the risk grading by American Society of Aneshesiologists, previous history of chest surgery, respiratory comorbidity, diffusion capacity for carbon monoxide of the lung, operation time, anastomosis, average days of postoperative hospitalization, death within 30 days after surgery, respiratory complications, pleural effusion or empyema, and poor healing of the incision were statistically associated with cervical anastomotic leakage (all P<0.05). Multivariate analysis showed that previous history of chest surgery, hepatic insufficiency, manual anastomosis, prolonged postoperative hospitalization, and poor healing of the incision were independent risk factors for cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy (all P<0.05).@*Conclusions@#Previous history of chest surgery, hepatic insufficiency, poor healing of the incision, manual anastomosis and prolonged postoperative hospitalization were significantly associated with cervical anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy. It′s important to strengthen perioperative nursing and surgical techniques to prevent anastomotic leakage after thoracoscopic-lapacoscopic esophagectomy.
