Objective To compare the difference between the short stature and normal boys testicular vol-ume,and to investigate the relationship between the short stature and testicular development.Methods Testicular testing for 70 cases of short stature by color doppler ultrasound from 4 to 12 years old,calculation of testicular volume average(MVT),references for the boy normal testicular volume provided by Peking union medical college hospital and the Beijing children's hospital,compared the above two groups.The short stature's height,weight,body mass index (BMI)for correlation analysis.Results The MVT of the short stature group were lower than normal,compared with the normal group differences statistically significant(P<0.05);The weight,BMI,MVT of idiopathic short stature had a tendency to decrease compared with complete lack of growth hormone deficiency from 10 to 12 years old;The short stature's height had low relativity with MVT(r=0.393,P=0.01 ),the weight had middle relativity with MVT(r=0.508, P<0.01),and the BMI had low relativity with MVT(r=0.352,P<0.01).Conclusion The testicular development of short stature is relatively slow,which should make early intervention for the gonad development of short stature.

Spine metastasis stereotactic body radiation therapy delivers conformal high radiation dose to the tumor target, and steep falloff dose gradients protect adjacent normal structures, especially spinal cord. Some studies demonstrated stereotactic body radiation therapy for metastatic tumors of the spine is safe and clinically effective. This technique markedly improved local control with an excellent symptomatic response compared with conventional external beam radiation therapy techniques, and is beginning to change the treatment paradigms for metastatic spine disease both as post-operative adjuvant therapy and primary definitive local treatment. Although the technique is being increasingly used in clinical practice, the optimal fractionation schedule remains uncertain. Based on the research of radiobiologic principles, radiological physics and clinical data, multiple session stereotactic body radiation therapy has some advantage in clinic.

Her-2 targeting therapy is an important part of the treatment for breast cancer with Her -2 overexpression.However,the therapeutic effectiveness is largely influenced by Her -2 resistance.Previous studies have confirmed that PI3K/AKT/mTOR signaling pathway is activated during the process of drug resistance to Her-2-targeting therapy.Therefore,investigating the PI3K/AKT/mTOR signaling pathway and drugs -targeted pathway are important for the treatment of breast cancer .

The academic orientation determines the development direction of the subject, and also puts forward the corresponding requirements for the professional teaching. The deep development of anes-thesiology, perfect preoperative evaluation, refined management of clinical anesthesia and ultimately improv-ing the prognosis of patients are the total development directions of anesthesiology. Perioperative patient home (PSH) advocates taking patients as the center, dominated by anesthesia, based on evidence-based medicine in the perioperative period, solidarity and cooperation of multiple disciplines, the integration of a variety of medical resources, and providing continuous and efficient medical services for patients. PSH is required to ensure the safety of clinical anesthesia, reduce the incidence of anesthesia mortality and serious
complications, and improve the long-term survival rate and quality of life by improving the clinical work of the department of anesthesia. Practicing PSH, the anesthetic doctors should have the academic idea of the treatment of anesthesia. The concept requires making comprehensive use of a variety of teaching methods, putting emphasis on the training of basic knowledge, and in the teaching of basic knowledge, infiltrating the overall and local thinking and using lecture method in cooperation with the case teaching. To make solid promotion of PSH concept, we should use CBL teaching, strengthening the management of clinical anesthesia, and striving to promote the clinical practice of PSH.

Objective To explore the mechanism of the cumulative biological effect of acupoint laser radiation and investigate its analgesic effect by comparing the therapeutic effects of semiconductor laser radiation versus acupuncture at point Zusanli(ST36) in acute adjuvant arthritis rats and to provide the experiment-based theoretical foundation and basis for the course of treatment of acute arthritis pain by clinical use of semiconductor laser. Method A rat model of AA was made by subcutaneous injection of complete Freund's adjuvant into rat toe. Eighty rats were randomly allocated to eight groups:model, blank, three-day laser radiation, five-day laser radiation, seven-day laser radiation, three-day acupuncture, five-day acupuncture and seven-day acupuncture treatment groups, 10 rats each. The three laser groups separately received 650 nm semiconductor laser radiation. The three acupuncture groups separately received acupuncture with a filiform needle at point Zusanli(ST36) on the inflammation-affected side. Rat general condition, body weight, pain threshold value and ankle swelling degree were observed. Serum inflammatory factors IL-1、TNF-αand IFN-γcontents were measured by ELISA. Result There were statistically significant posttreatment differences in body weight, joint swelling degree and pain threshold between the laser treatment and acupuncture treatment groups of rats (P<0.05). There was a statistically significant post-treatment difference in joint swelling degree between three-day laser, five-day laser and seven-day laser treatment groups (P<0.05). Pain threshold was lowest at five days after treatment and increased somewhat at seven days after treatment in both the three-day laser and three-day acupuncture treatment groups. The IL-1 content tended to decrease on the whole and had a decreasing tendency at three and five days after treatment in both laser and acupuncture treatment groups. At seven days after treatment, it reached the lowest value in the laser treatment group but had a marked increasing tendency in the acupuncture treatment group. The IFN-γcontent had an increasing tendency at three and five days after treatment in both laser and acupuncture treatment groups. The IFN-γcontent tended to change gently in the laser treatment group from day five to seven after treatment. It tended to decrease from day five to seven after acupuncture treatment but was still higher than in the three-day acupuncture treatment group. The TNF-αcontent tended to decrease from day three to five after treatment in both laser and acupuncture treatment groups. From day five to seven after treatment, it tended to decrease gently in the laser treatment group but tended to increase slightly in the acupuncture treatment group. Conclusion Both semiconductor laser radiation and acupuncture at point Zusanli have an anti-inflammatory and analgesic effect and can relieve the general symptoms in AA rats, but semiconductor laser radiation is significantly superior to acupuncture treatment in eliminating inflammation and easing pain and produces a more timely and better therapeutic effect. After semiconductor laser radiation at acupoints, the related serum cytokines tended to increase or decrease slowly in AA rats after the turning point appeared during the treatment, which embodies the parabola feature of laser radiation treatment. It is showed that with an increase in laser radiation length, the biological effect of laser accumulates, suggesting that attention should be paid to the cumulative effect during laser treatment.

This study was aimed to investigate rules of medicine selections of four Meng-He (MH) medical schools. Based on frequency analysis and Apriori algorithm of association rules, data mining was conducted on 60 cases of four MH medical schools in the treatment of Chuan syndrome. The results showed that among 60 cases, Xing-Ren (XR), Ban-Xia (BX), Fu-Ling (FL), Hua-Ju-Hong (HJH), Su-Zi (SZ) and Bu-Gu-Zhi (BGZ) were the most com-monly used single medicine. The most commonly used medicine groups were SZ-HJH-FL, XR-Y i-Y i-Ren (YYR), XR-HJH, XR-SZ and so on. It was concluded that four MH medical schools in the treatment of Chuan syndrome mainly used antitussive and antiasthmatic Chinese medicines such as YR, BX, SZ, and complemented with BGZ for deficiency-nourishing, FL for dampness-removing, HJH for qi-regulating. It provided references for the clinical practice and treatment of Chuan syndrome.
