After Achilles tendon (AT) rupture operation,traditional gypsum immobilization must lead to AT in a condition of a tension-free or even "disuse"-negative balance healing system,which may inhibit the key opportunity of AT healing process to induce "active" mechanical signals stimulation,and AT "passively or intermittently" accepts the mechanical stimulation even applying the ultrasound,vibration and other mechanical stimulation to AT in the course of treatment. If using the method of active movement after operation,it can accelerate the AT healing,maintain function and promote re-construction of the AT,thereby help to restore the biomechanical properties of AT. Using proteomics techniques can reveal the mechanical signal transduction mechanisms of kinesiatrics promoting the AT healing in the high-throughput molecular level.

5.Radiotherapy in the treatment of uterine sarcomas
Chinese Journal of Obstetrics and Gynecology 2001;36(3):159-161
Objective To study radiotherapy in the treatment of uterine sarcomas and response to radiation in primary or recurrent uterine sarcomas. Methods A total of 102 uterine sarcomas treated in the Cancer Hospital from May 1960 to June 1999. A retrospective review of 45 patients receiving surgery alone, 29 patients for postoperative radiotherapy, 4 radiotherapy alone, 24 recurrent sarcomas receiving radiotherapy. Results The 5-year overall survival for 45 patients treated with surgery alone and 29 patients managed by postoperative radiotherapy were 56.7% and 58.6% respectively (P>0.05). The addition of radiotherapy significantly reduced the local recurrence rate from 42.2% to 20.7% (P<0.05). The tumor was disappeared completely by treatment of radiotherapy alone in 3 patients of primary uterine cervix sarcomas. 1 patient was free of disease at 36 months. Other 2 patients died 9 and 11 months later because of distant metastases. The complete and partial response rate of radiotherapy was 50.0% for recurrent tumors. The radiotherapetic sensibility of endometrial stromal sarcomas, mixed mesodermal sarcomas and leiomyosarcomas was downward tendency in turn.Couclusions The postoperation adjuvant radiotherapy reduced the pelvic recurrent significantly. Radiotherapy should be used in the treatment of uterine sarcomas as an important part of combination therapy.

Objective To investigate the environmental factors affecting neonatal neurobehavioral development and its sensitivities.Methods Neonatal behavioral neurological assessment (NBNA)and lead levels in umbilical cord blood and meconium were determined for103randomly selected neonates delivered at the section of Obstetrics and Gynecology,First Metallurgical Construction Company Hospital,from January to October1999,and the other relevant factors were investigated by questionnaire at the same time.The NBNB total score was described as a dependent variable and24relevant factors such as umbilical cord blood lead and meconium lead level,etc,as independent variables.Logistic regression analysis was used to ana-lyze the associated factors at P=0.10level.Results The factors selected in the Logistic regression model included:gestational age,month of taking medicine in gestational period,hemoglobin concentration,pregnant womans psychology,meconium lead level and taking medicine during gestational period.Conclusion Neonatal neurobehavioral development could be affected by many factors.Good nutrition,longer gestational age and maintaining good psychological status during pregnancy might be benefi-cial to neonatal neurobehavioral development.However,taking medicine during the gestational period and a high meconium lead level could be harmful to neonatal neurobehavioral development.
8.Pharmacokinetics of antibody-drug conjugates and their research progress in the treatment of gastrointestinal malignancies
Acta Pharmaceutica Sinica 2023;58(9):2632-2639
The morbidity and mortality of gastrointestinal malignancies are the highest in the world. For patients with poor response to conventional chemotherapy, new treatment methods are urgently needed. In recent years, under the background of precision medicine, antibody-drug conjugates (ADCs) with high tumor specificity and potent toxicity have become a hot research spot in the field of biomedicine. However, due to the complex structure and mechanism of ADCs, its pharmacokinetic research is facing great challenges which are the biggest resistance to the development of ADCs at present. In this case, it is of great significance to understand the pharmacokinetic properties of ADCs and make use of it to improve the efficacy of ADCs in the treatment of gastrointestinal malignancies. Based on the basic composition and mechanism of ADCs, this review summarizes the pharmacokinetic properties of ADCs, discusses its recent advances in the treatment of gastrointestinal malignancies, in order to provide more references for follow-up research on ADCs.

Objective:
To examine the causal relationships between obesity, peripheral blood lipid indicators and non-small cell lung cancer (NSCLC) using Mendelian randomization (MR) method, so as to provide the basis for developing NSCLC prevention and control strategies.
Methods:
Genetic variation data of three obesity evaluation indicators, including body mass index (BMI), body fat ratio (BFR) and waist-to-hip ratio (WHR), and seven peripheral blood lipid indicators, including triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and lipoprotein a [LP (a)] were collected through genome-wide association studies (GWAS) and related public databases. Potential causal relationships between obesity, peripheral blood lipid indicators and NSCLC were analyzed using inverse-variance weighted (IVW) method and multivariable MR analysis upon a random effect model. Heterogeneity and horizontal pleiotropy of instrumental variables were evaluated using Cochran's Q test and MR-Egger regression.
Results:
There was statistically association between BMI with NSCLC (OR=1.256, 95%CI: 1.087-1.451); there were no statistically associations between BFR, WHR, seven peripheral blood lipid indicators and NSCLC (all P>0.005). There was heterogeneity in the association between BMI, BFR, WHR, TG, HDL-C and NSCLC (all P<0.05); no horizontal pleiotropy of instrumental variables was found (all P>0.05). There was no statistically association between BMI and NSCLC after adjusting BFR (OR=1.367, 95%CI: 0.878-2.128); there was still statistically association between BMI and NSCLC after adjusting WHR and peripheral blood lipid indicators (both P<0.05).
Conclusions
The increase of BMI is associated with the increased risk of NSCLC incidence. BFR may be a potential influencing factor for the association between BMI and NSCLC.

Objective To observe the effect of electromyographic biofeedback therapy on hemiplegia of patients with cerebral infarction.Methods 122 hemiplegic patients were divided into observed group (n=61) and control group (n=61). The two groups all received physical therapy 6 times a week for two weeks in addition to regular medication. In the meantime the observed group received electromyographic biofeedback. All patients were evaluated with NIHSS, Fugl-Meyer Assesment(FMA) and Barthel Index(BI). Results The improvement in the observed group was greater than in control group in NIHSS, FMA and BI.Conclusion The eletromyographic biofeedback can improve motor function of hemiplegic patients and do benefit their activities of daily living.
