ABSTRACT

AIM: To understand the current status and differences in visual acuity of children of the same age from different regions of Xi'an, and to take an effective basis for the prevention of children's myopia.METHODS: Random stratified sampling was used to select the uncorrected distance visual acuity and computed dioptric data of 41 285 children aged 6-12 from 6 towns, 10 urban and rural areas and 112 country schools screened by Xi'an Central Hospital in December 2022.RESULTS: The myopia detection rate in different regions of Xi'an is 47.16% in towns, 38.59% in urban and rural areas, and 32.29% in the country, and the total myopia rate is 37.50%. The myopia rate of 6-12 years old in towns is higher than that in urban and rural areas, and that of urban and rural areas is higher than that of country; the myopia rate of girls is higher than that of boys; myopia rate increases with age; mild myopia: the myopia rate in towns is significantly higher than that of the urban and rural areas and the country; high myopia: the myopia rate in the country is significantly higher than that of the towns and the urban and rural areas. The total rate of deficient hyperopia reserves in different regions of Xi'an is 92.08% in towns, 93.67% in urban and rural areas, and 90.92% in the country, and the total rate of deficient hyperopia reserves is 92.09%. The rate of deficient hyperopia reserves at the age of 6-12 is higher in the urban and rural areas than in the towns, and higher in the towns than in the country; the total rate of deficient hyperopia reserve is higher in girls than in boys; it is the peak period of the development of hyperopia reserve rate before the age of 8.CONCLUSION: The total myopia rate and the total vision reserve deficiency rate of 6-12 years old in different regions of Xi'an are different, and 8-9 years old is the accelerated period of myopia development, and the peak of deficient hyperopia reserve is before the age of 8 years old. With the growth of age, the myopia rate shows a certain growth trend, and the rate of deficient hyperopia reserve shows a decreasing trend after reaching the peak. The total myopia rate and insufficient acuity reserve rate of girls are higher than those of boys.

ABSTRACT

Aim To investigate the regulatory effect of morphine postconditioning in the LSG on remodeling after myocardial infarction. Methods SD rats were randomly divided into four groups: sham operation group (Sham), myocardial infarction group (MI), myocardial infarction + saline group (Control) and myocardial infarction + morphine postconditioning group (MI + Morphine) . The rat MI model was constructed by ligating the left anterior descending coronary artery, and then morphine was given to the LSG by percutaneous posterior approach. After four weeks, the changes of cardiac function in rats were detected by ultrasound. Masson staining was used to detect fibrosis changes; the expression of Collagen I and Collagen III protein was detected by Western blot. The mRNA expression of ANP and BNP was detected by RT-qPCR. The expression of JJLOR in LSG was detected by immunofluorescence. The concentration of catecholamine in plasma and myocardial tissue was detected by ELISA. Results Compared with the sham group, the cardiac function of the MI group was significantly impaired, the myocardial tissue showed significant fibrosis changes, and the concentration of catecholamine in plasma and myocardial tissue significantly increased. Compared with the control group, the MI + Morphine group reduced myocardial fibrosis collagen deposition in rats after MI, inhibited the expression of ANP and BNP in myocardial tissue, reduced the concentration of catecholamine, and improved the cardiac function of MI rats. Immunofluorescence results showed that JJLOR was expressed in LSG after MI and increased after morphine postconditioning. Conclusions This study shows that morphine postconditioning in the LSG has a protective effect on myocardial remodeling after myocardial infarction. The mechanism may be related to the activation of JJLOR in the LSG by morphine and the reduction of catecholamine release from sympathetic nerve endings.

ABSTRACT

ObjectiveTo investigate the expression of glial cell line-derived neurotrophic factor (GDNF) and androgen receptor (AR) in testicular peritubular cells (TPCs) of cryptorchidism mouse models and explore the theoretical significance of cryptorchidism-induced spermatogenesis dysfunction. MethodsA total of 30 five-week-old male ICR rats were divided randomly by using random number table method into 6 groups. Cryptorchidism was surgically induced in 3 randomly selected groups and the other 3 groups underwent sham surgery as the control groups. On days 4, 7 and 14 after surgery, we harvested the mice testes of the 3 groups and their corresponding control groups, then measured the testicular volumes, analyzed the testicular histopathology and detected the mRNA and protein expression levels of AR and GDNF in TPCs by immunofluorescence, real-time PCR and Western blot. ResultsIn normal control groups, on days 4, 7 and 14 after surgery, the testicular volumes were (125.58±19.22) mm3,(123.45±20.12) mm3, (140.09±13.62) mm3 , respectively. Clear layers of spermatogenic cells were well arranged and abundant sperm cells were found. Peritubular cells were morphologically homogeneous, with slim-spindle appearance and normal cell thickness. The mRNA expression levels of AR were 1.00±0.05, 1.06±0.07 and 1.19±0.13; GDNF mRNA 1.00±0.04, 1.09±0.05, and 1.10±0.07. The protein expression levels of AR were 1.01±0.01, 0.79±0.02 and 1.01±0.04; GDNF protein (18.68±0.43) pg/mL, (14.39±0.36) pg/mL and (16.88±0.37) pg/mL. In cryptorchidism groups, on days 4, 7 and 14 after surgery, the testicular volumes were (115.64±3.91) mm3, (69.51±14.97) mm3 and (44.86±5.56) mm3, respectively. Spermatogenic cells were disorganized, seminiferous tubules were disrupted, peritubular cells shrank, bent and fractured. The mRNA expression levels of AR were 0.76±0.06, 0.53±0.04, and 0.29±0.02; GDNF mRNA 0.72±0.05, 0.42±0.02 and 0.30±0.03. The protein expression levels of AR were 0.54±0.02, 0.98±0.04 and 0.31±0.01; GDNF protein (8.50±0.34) pg/mL, (17.44±0.32) pg/mL and (6.83±0.34) pg/mL. Statistically significant differences (P < 0.05) were found in 7-day and 14-day testicular volumes between control and cryptorchidism groups but not in the 4-day testicular volume (P > 0.05). Testicular volumes, AR and GDNF mRNA and protein expression in control groups had no statistically significant difference (P > 0.05), while those in cryptorchidism groups showed a trend of gradual decline in the amount and the differences between groups were statistically significant (P < 0.05). ConclusionsIn surgery-induced cryptorchidism mice, after the induction, the expression of AR and GDNF in TPCs showed a gradual decrease over time. AR and GDNF play a major role in mediating the TPCs damage in cryptorchidism. This study provides a theoretical basis for mechanism researches of cryptorchidism-induced spermatogenesis dysfunction.

ABSTRACT

Objective:To evaluate the incidence, clinical characteristics and prognosis of second primary malignancies (SPMs) among patients with hypopharyngeal carcinoma (HPC) in real-world analysis.Methods:A total of 594 HPC patients admitted to Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from 2010 to 2018 were retrospectively analyzed.The incidence and clinical characteristics of HPC patients complicated with SPMs were analyzed. Clinical efficacy was compared among different groups.Results:With a median follow-up time of 66.9 months, SPMs were present in 36.4% (216/594) of HPC patients: 22.2% (132/594) were synchronous and 14.1% (84/594) were metachronous. The upper aerodigestive tract was the most common involved region. Compared with patients without SPMs, patients with synchronous and metachronous carcinoma in situ had similar 5-year overall survival (OS) of 42.2% vs. 44.5% ( P=0.958) and 62.2% vs. 44.5% ( P=0.240), respectively. Patients with synchronous invasive SPMs had a worse 5-year OS of 27.2% vs. 44.5% in their counterparts without SPMs ( P=0.001). Patients with metachronous invasive SPMs had similar 5-year OS of 50.2% vs. 44.5% in their counterparts without SPMs ( P=0.587). SPMs accounted for 42.5% of total death in metachronous invasive SPMs group. Conclusions:Patients with HPC have a high probability of developing SPMs. Moreover, the incidence of complicated with esophageal/gastric carcinoma in situ or metachronous SPMs exerts no effect on prognosis, while the occurrence of synchronous SPMs significantly affectes the prognosis of patients. However, the incidence of SPMs is still one of the main death causes in metachronous invasive SPMs group.

ABSTRACT

Objective:To investigate the effects of dezocine combined with sufentanil on continuous epidural analgesia after cesarean section.Methods:Eighty-six pregnant women who were scheduled for cesarean section in Guoyang Hospital of Traditional Chinese Medicine from February to December 2021 were included in this randomized controlled study. These women were divided into an observation group and a control group ( n = 43/group). The women in the observation group underwent epidural analgesia with dizocine, sufentanil, and ropivacaine, while those in the control group underwent epidural analgesia with dizocine and ropivacaine. The visual analogue score, Ramsay sedation score, Bruggrmann comfort scale score, and the incidence of adverse reactions were compared between the two groups. Results:At 4, 8, 12, 24 hours after surgery, the visual analogue score (VAS) in the observation group was significantly lower than that in the control group ( t = 2.34, 5.89, 15.36, 16.23, all P < 0.05). At 4, 8, 12, and 24 hours after surgery, Ramsay sedation score in the observation group was significantly higher than that in the control group ( t = -6.31, -7.64, -7.49, -7.41, all P < 0.001). At 4, 8, 12, and 24 hours after surgery, Bruggrmann comfort scale score in the observation group was significantly higher than that in the control group ( t = -7.60, -10.40, -14.53, -13.80, all P < 0.001). There was a significant difference in the number of effective analgesic pump compressions between the observation and control groups [(3.00 ± 1.41) times vs. (7.23 ± 1.31) times, t = 14.42, P < 0.001]. No adverse reactions were observed in the observation group within 24 hours after surgery. Conclusion:Dezocine combined with sufentanil for epidural analgesia can effectively improve the analgesic effects after cesarean section and is highly safe.

ABSTRACT

Objective:Under the background of "new medical science", to construct a whole-process education path with "education as the driving force - moral cultivation as the core", and to provide a decision-making basis for the reform, innovation, and development of humanistic quality education in medical colleges.Methods:Five-year clinical medical students (freshman to fifth graders) from Qiqihar Medical University were selected as the research objects. The evaluation model and questionnaire of humanistic quality of clinical medical students were constructed by literature analysis. The Questionnaire Star platform was used to investigate and collect data by random sampling of clinical medical undergraduates, and the data results were analyzed by SPSS 26.0 to explore the path of building the whole-process education.Results:The empirical research on the cultivation of humanistic quality of medical students showed that the average humanistic attitude score of medical students was (3.47±0.75) points. From the perspective of gender, the scores of humanistic cognition, attitude, and behavior of male students were 2.81, 3.68, and 3.22 points, respectively, which were all significantly higher than those of female students (2.52, 3.22, and 2.95 points, respectively) ( P<0.05). The data from freshmen to the fifth graders showed that humanistic cognition, attitude, and behavior scores all presented an increasing trend with the grade. Using the "Knowledge, Attitude/Belief, Practice" model, it was found that the cognitive rate of humanistic quality of medical students was relatively ideal, and the awareness rate of medical students in different grades was different. The cross analysis showed that the effect of ideological morality and political literacy education on medical students in medical colleges had a significant cross-relationship with multiple choice questions. Conclusion:The humanistic quality of clinical medical students needs to be improved, and the cultivation of medical humanistic quality should run through the whole process from the first year to the fifth year, so as to improve the comprehensive training of professional ability and promote the all-round development of medical students.

ABSTRACT

"Flipped Classroom" is a new kind of "student-centered" teaching model, which can give full play to the advantages of both sides of teaching and learning. According to this teaching model, we redesigned the teaching process, in which the students studied by themselves and built their own knowledge system. Moreover, each of them took part in three stages of experimental design including digital signal collection, analysis and processing in groups. Results have shown that this model can fully stimulate students' learning interest, not only helps students to deepen understanding of digital signal processing theory knowledge, but also strengthen the ability of autonomous learning and team collaboration. The teaching model maybe have certain reference function in comprehensive experiment teaching of Digital Signal Processing course for biomedical engineering specialty.

ABSTRACT

Objective:To evaluate the efficacy and safety of phacoemulsification combined with gonioscopy-assisted angle plasty (Phaco-GAAP) for primary angle closure glaucoma (PACG) with cataract.Methods:A case series study was carried out.Twenty-five eyes of 22 patients with PACG and cataract were enrolled in Beijing Tongren Hospital from April 2022 to August 2022.All of the patients received Phaco-GAAP surgery.During the operation, viscoelastic-assisted goniosynechialysis was performed at first, followed by a secondary angle plasty for residual peripheral anterior synechiae (PAS) based on the quantified assessment by gonioscopy, and the extent of PAS was recorded intraoperatively.The operated eyes were followed at 1 day, 1 week, 1 month and 3 months after surgery to evaluate intraocular pressure (IOP), PAS range, the number of anti-glaucoma drugs application, operation-related complications, and success rate.The qualified success rate was defined as medicine-controlled IOP ≤21 mmHg after surgery, and complete success rate was defined as IOP ≤21 mmHg without any anti-glaucoma medication.This study complied with the Declaration of Helsinki and was approved by the Ethics Committee of Beijing Tongren Hospital (TRECKY2021-136). Written informed consent was obtained from each patient prior to entering the research cohort.Results:The extent of PAS was [270(225, 360)°], [165(110, 215)°] and [100(35, 175)°] at preoperation, first and secondary angle plasty, respectively, showing a significant difference among them ( χ2 =40.742, P<0.001). The PAS range was significantly reduced at first angle plasty in comparison with preoperation and was significantly reduced at secondary angle plasty in comparison with at first angle plasty (both at P<0.001), and the proportion of the angle PAS range ≥180° decreased from 48% to 24% after second angle plasty.In 13 eyes finished gonioscopy, the PAS range was [240(195, 305)°], [60(25, 182.5)°], [170(120, 275)°]and [180(140, 280)°]at preoperation, at the end of operation, postoperative 1 month and 3 months, respectively, with a significant difference ( χ2 =23.631, P<0.001). The PAS range was significantly smaller at postoperative 1 month, 3 months than that at preoperation (both at P=0.004) and larger than that at the end of operation ( P=0.011, P=0.003). The IOP was (40.19±17.23), (15.80±7.98), (13.89±5.09), (12.80±3.79) and(13.24±2.78) mmHg before operation and 1 day, 1 week, 1 month and 3 months after operation, respectively, showing a significant difference ( F=44.031, P<0.001), and the IOP was significantly reduced after operation (all at P<0.001). The PAS range at the end of operation was positively correlated with preoperation ( rs=0.409, P=0.042). The complete and qualified success rates were 95.8%, 95.8% for postoperative 1 month, 95.8% and 100% for postoperative 3 months, respectively.The primary complication was intraoperative anterior chamber angle hemorrhage, with an incidence of 68%. Conclusions:Phaco-GAAP can intraoperatively quantify PAS range and guide secondary angle plasty, therefore, it is an effective and safe surgical intervention for PACG with cataract.

ABSTRACT

Objective:To study the clinical features and risk factors of pulmonary hemorrhage in extremely preterm (EPT) infants.Methods:From February 2018 to January 2022, EPT infants admitted to NICU of our hospital and diagnosed with pulmonary hemorrhage were retrospectively assigned into the observation group and those without pulmonary hemorrhage were assigned into the control group. Univariate analysis and multivariate logistic regression analysis were used to compare the clinical features and determine risk factors of pulmonary hemorrhage in EPT infants.Results:A total of 114 EPT infants were included, including 28 cases (24.6%) in the observation group with pulmonary hemorrhage and 86 cases in the control group. Pulmonary hemorrhage mainly occurred within the first week after birth. Univariate analysis showed that the observation group had higher incidences of following events than the control group: birth asphyxia, delivery room intubation, severe respiratory distress syndrome, hyperglycemia, thrombocytopenia, severe acidosis, shock, score for neonatal acute physiology with perinatal extension-Ⅱ (SNAPPE-Ⅱ) ≥37 and the highest lactate level. Birth weight was lower in the observation group than the control group ( P<0.05). Logistic regression analysis showed that SNAPPE-Ⅱ≥37, shock and hyperglycemia were risk factors of pulmonary hemorrhage ( OR=4.081, 4.610 and 3.355, respectively, all P<0.05). The incidences of mortality and intracranial hemorrhage in the observation group were higher than the control group. The duration of mechanical ventilation in the observation group was longer than the control group ( P<0.05). No significant differences existed in the duration of nasal continuous positive airway pressure, assist mechanical ventilation and total oxygen use, the incidences of grade Ⅱ-Ⅲ bronchopulmonary dysplasia, retinopathy of prematurity and the length of hospital stay ( P>0.05). Conclusions:SNAPPE-Ⅱ≥37, shock and hyperglycemia are early risk factors for pulmonary hemorrhage in EPT infants. EPT infants with pulmonary hemorrhage have higher incidences of mortality and intracranial hemorrhage, requiring longer periods of mechanical ventilation.

ABSTRACT

AIM: To explore the reasons for screening failure of healthy subjects in clinical trials of orally inhaled drug products (OIDPs). METHODS: Screening data of 1 432 healthy subjects who participated in clinical trials of OIDPs were collected. The main reasons for the screening failure, gender differences in screening failure rate and the correlation between age and screening failure rate were summarized and analyzed. RESULTS: The screening failure rate was 72.4 % and increased with age. The failure rate was slightly higher in females than in males. Besides abnormal vital signs (17.3%), abnormal laboratory test results (16.5%) and withdrawal of consent (7.6%), poor venous condition (13.9%), positive for cigarette test results (12.6%) and failure in inhalation training (7.1%) were also the other three main reasons affecting the screening success rate. Abnormal vital signs and poor venous conditions were the primary screening failure reasons for males and females, respectively. CONCLUSION: The screening success rate could be improved by informing fully and communicating effectively, selecting young subjects with strong understanding abilities, and enhancing the training skills of investigators.

ABSTRACT

Aim To investigate the role of transient receptor potential ankyrin 1 receptor in remote preconditioning of trauma-induced cardioprotection against myocardial ischemia-reperfusion injury and related mechanism. Methods SD rats were randomly divided into five groups: Sham operation group(Sham), model group(IR), remote preconditioning of trauma group(RPCT), TRPA1 inhibitor+remote preconditioning of trauma group(TCS+RPCT)and TRPA1 inhibitor group(TCS). The model of myocardial ischemia/reperfusion in rats was established, and the hemodynamics was monitored throughout the process. After reperfusion, the rat heart was taken to measure the myocardial infarction area and myocardial apoptosis rate, the activity and protein expression of mitochondrial aldehyde dehydrogenase 2(ALDH2)and the expression of 4-hydroxynonenal(4-HNE)were detected. Results Compared with sham group, myocardial infarction area and myocardial apoptosis cell increased. Meanwhile, the activity and expression of ALDH2 decreased and the production of 4-HNE increased in IR group. However, compared with IR group, RPCT group had decreased myocardial infarction area and the rate of cardiomyocyte apoptosis, the activity and expression of ALDH2 increased, the production of 4-HNE decreased. And then, compared with RPCT group, TCS+RPCT group reduced the myocardial protective effect of remote preconditioning of trauma. Conclusions TRPA1 receptor mediates the effect of remote preconditioning of trauma alleviating myocardial ischemia/reperfusion injury in rats. Its mechanism may be related to regulating ALDH2 activity and protein expression, and affecting the content of 4-HNE.

ABSTRACT

Objective:To analysis the clinical features and prognosis in oropharyngeal carcinoma with secondary primary tumor. Methods:A retrospective analysis was performed on 468 pathologically confirmed oropharyngeal cancer as the primary tumor patients with p16 status, excluded distant metastasis, and admitted to the Chinese Academy of Medical Sciences from January 2010 to December 2020. The clinical features and prognosis of the secondary primary tumor were analyzed. Results:Among 468 patients with oropharyngeal cancer treated at initial diagnosed, 222 cases were P16-negative. With a median follow-up time of 64.3 months, 66 cases developed second primary cancer, with an incidence of 29.3%, among which 63.6%(42/66) were synchronous and 36.4%(24/66) were heterochronous, esophagus was the most commonly involved site. The 5-year OS of p16-negative oropharyngeal carcinoma with synchronous second primary cancer, without second primary cancer and with heterogeneous second primary cancer were 26.3% and 57.3% and 73.2%(P=0.001); The second primary cancer accounted for 11.2%(12/107) of the deaths in the whole group, among them, the heterochronous second primary accounted for 75.0%(9/12). There were 246 patients with p16 positive, with a median follow-up time of 52.4 months, 20 patients developed second primary cancer(8.1%). Among them, 65.0%(13/20) were synchronous and 35.0%(7/20) were heterochronous. Esophagus was the most commonly involved site. The 4-year OS of p16-positive with synchronous, heterochronous and non-second primary cancer group were 51.9%, 80.7% and 83.3%. Secondary primary cancer accounted for 3.8%(2/52) of all deaths in p16 positvie group. Conclusion:The incidence of second primary cancer of p16 positive and negative oropharyngeal carcinoma were different. The esophagus was the most commonly involved site regardless of p16 status. Regardless of p16 status, the survival of patients with synchronous second primary cancer was worse than those without second primary cancer. For p16-negative oropharyngeal carcinoma, the prognosis was better in patients with heterogeneous second primary cancer, the second primary cancer is one of the main causes of death.

ABSTRACT

Objective:This study aimed to evaluate the clinical features and treatment outcomes of the value of response-adapted treatment following radiotherapy and induction chemotherapy follwing subsequent comprehensive therapy in patients with resectable locally advanced hypopharyngeal carcinoma. Methods:This cohort study was conducted from September 2010 to September 2020 in our hospital, 231 patients pathologically confirmed stage Ⅲ and ⅣB resectable locally advanced hypopharyngeal carcinoma included. For the IC-directed ART strategy, IC is used to select good candidates to receive radical RT or CCRT, and others undergo surgery. He response-adapted strategy was determined based on the primary tumor response, which was evaluated at a dose of 50 Gy. If the response reached complete response or partial response(more than 80% tumor regression), patients received radical RT or CCRT; otherwise, they received surgery, if possible, at 4 to 6 weeks after RT. The end points of the study were OS(overall survival), progression free survival(PFS), locoregional recurrence-free survival(LRRFS) and LDFS. Results:In IC-directed group, 75.0%(57/76) patients reached PR after 2 cycles of induction chemotherapy. While in RT-directed group, 70.3%(109/155) patients reached large PR at dose of 50 Gy. The median interquartile range follow-up period of the whole cohort was 63.8 months. The 5-year OS, PFS, LRRFS and SFL of the whole cohort were 47.9%、39.6%、44.3% and 36.2%, respectively. In evaluations based on the different treatment strategies, the 5-year OS and SFL were 51.3% versus 37.0%(HR 0.67; 95%CI 0.43-1.05; P=0.07) and 27.8% versus 39.8%(HR 0.68; 95%CI 0.46-0.99; P=0.04) between IC-directed and RT-directed groups. In additional, surgery complications did not significantly differ between these two groups. Conclusion:In this cohort study, the response-adapted strategy based on an early RT response facilitated better treatment tailoring, and higher laryngeal preservation compared with IC-directed strategies. This approach could provide a feasible laryngeal preservation strategy in patients with resectable locally advanced hypopharyngeal carcinoma.

ABSTRACT

In this experiment, the PK/PD fitting model of Chuanxiong(Chuanxiong Rhizoma) in the treatment of rheumatoid arthritis was established in the form of acupoint combined with external application gel paste. Firstly, the rheumatoid arthritis model was induced by ovalbumin, and the articular fluid of rabbits was extracted by microdialysis. The pharmacokinetic process of Chuanxiong in rabbit articular fluid was analyzed by UPLC-MS/MS, and the pharmacokinetic model was established. The pharmacodynamic effects of Chuanxiong on inflammatory factors IL-1β, TNF-α, and IL-6 were analyzed by enzyme-linked immunosorbent assay(ELISA). The pharmacodynamic model was established, and the PK/PD model was obtained by fitting the data of pharmacokinetics and pharmacodynamics. The results of pharmacokinetics showed that the concentration of ligustrolide A in the articular cavity by drug administration on classical acupoint Zusanli(ST 36) was higher than that by Yanglingquan(GB 34), which reflected the advantage of typical acupoint, while ligustrazine concentration was higher after administration through Yanglingquan than through Zusanli, which was different from the traditional acupoint theory. The results of pharmacodynamics showed that the drug had lag effect. The PK/PD model was constructed by fitting the data. When IL-1β was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=115.28C_e/(3 316.72+C_e), E=108.73C_e/(2 993.47+C_e), and E=101.34C_e/(3 028.51+C_e). When TNF-α was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=68.31C_e/(3 285.16+C_e), E=59.27C_e/(2 919.86+C_e), and E=53.61C_e/(2 862.87+C_e). When IL-6 was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=59.92C_e/(3 461.17+C_e), E=58.34C_e/(2 723.51+C_e), and E=49.17C_e/(2 862.76+C_e). The parameters showed that there were significant differences in E_(max), EC_(e50) and k_(eo). The analysis of data found that the PK/PD fitting effect of Zusanli, a typical acupoint, was the best, which proved that it was still the best site for drug administration. To sum up, it shows that there may be bidirectional selectivity between drugs and acupoints.

ABSTRACT

The Guidelines for prevention and treatment of colorectal adenoma with integrated Chinese and western medicine are put forward by Nanjing University of Chinese Medicine and approved by China Association of Chinese Medicine. According to the formulation processes and methods of relevant clinical practice guidelines, the experts in clinical medicine and methodology were organized to discuss the key problems to be addressed in the clinical prevention and treatment of colorectal adenoma(CRA) and provided answers following the evidence-based medicine method, so as to provide guidance for clinical decision-making. CRA is the major precancerous disease of colorectal cancer. Although the prevention and treatment with integrated Chinese and western medicine have been applied to the clinical practice of CRA, there is still a lack of high-quality guidelines. Four basic questions, 15 clinical questions, and 10 outcome indicators were determined by literature research and Delphi questionnaire. The relevant randomized controlled trial(RCT) was retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, Web of Science, and 2 clinical trial registries, and finally several RCTs meeting the inclusion criteria were included. The data extracted from the RCT was imported into RevMan 5.3 for evidence synthesis, and the evidence was evaluated based on the Grading of Recommendations, Assessment, Development, and Evaluations(GRADE). The final recommendations were formed by the nominal group method based on the evidence summary table. The guidelines involve the diagnosis, screening, treatment with integrated Chinese and western medicine, prevention, and follow-up of colorectal adenoma, providing options for the clinical prevention and treatment of CRA.
