Since the reform and opening up, the government of China has continuously adjusted its foreign medical policy and vigorously guided foreign investment to set up medical institutions in pilot provinces and cities. Based on healthy China 2030 plan, the paper summed up the foreign medical policy adjustment's process from its establishment, stagnation, and development to reform in China. The government of China liberalizes the market for foreign medical gradually, but the foreign medical institution is facing a series of bottlenecks, such as the lack of le-gal regulations, the cumbersome of approval procedures, and the limit of development and so on. The development of foreign medical care should be under the guidance of the country's legal and policy. Foreign medical institution can carry out some special medical care to improve the health of the residents.

Objective To explore the effect of a multimodal electroencephalogram ( EEG) data visualiza-tion system on the motor imagery ability of stroke survivors. Methods Twenty stroke patients were randomly di-vided into an experimental group and a control group, each of 10. Both groups were provided with brain-computer interface-based motor imagery ( MI) training. At the same time, the experimental group was monitored and guided using an online, multimodal EEG data visualization system developed in our department. The classification accuracy ( CA) and event-related desynchronization ( ERD) of the 2 groups′ motor imagery were compared before and after the treatment. Results Before the treatment, no significant differences in the average CA of MI were found be-tween the experiment group (50.92±2.08) and the control group (49.35±4.20)(P>0.05). After the treatment, however, the experimental group′s average CA had increased to (64.52±5.27), significantly higher than that of the control group (51.18±5.02). When the stroke patients imaged affected upper extremity movements, obvious ERD was observed in the α frequency around the bilateral central motor regions of both groups, especially in the experi-mental group, but without significant differences between the two groups. However, no significant changes were found in the ERD of theβwaves of the two groups( P>0.05) . Conclusion The proposed online multimodal elec-troencephalogram data visualization system can help stroke patients imagine movements actively. It is worth sprea-ding in clinical practice.

Objective To investigate the effects of different doses of dexamethasone (Dex) on bone mineral density (BMD) and body composition in Sprague-Dawley (SD) rats. Methods Forty 3-month-old female SD rats were divided into four groups:control group (Cont, saline), low dose Dex group (LDG, 1 mg/kg), medium dose Dex group (MDG, 2.5 mg/kg) and high dose Dex group (HDG, 5 mg/kg). Ten rats for each group. Dex was injected intramuscularly twice a week. The values of BMD and body composition were measured by DEXA densitometer at the beginning and 4-week of treatment. Results The body weights of different doses of Dex intervention groups were decreased after 1 to 4-week intervention compared with those of Cont group (P<0.01). After 4-week intervention, the total BMD, femur BMD, total bone mineral content (BMC), to-tal fat mass, trunk fat mass and leg fat mass were significantly increased in Cont group (P<0.01), while the total lean mass, trunk lean mass were significantly decreased (P<0.01). The total BMC, femur BMD, leg lean mass, leg fat mass were signifi-cantly lower in LDG group and MDG group than those of Cont group (P<0.05). The femur BMD, leg fat mass were signifi-cantly lower in LDG group and MDG group than those of HDG group (P<0.05). Conclusion The doses of 1 mg/kg and 2.5 mg/kg Dex have greater impact on the femur BMD and the leg composition in SD rats than that of Dex (dose of 5 mg/kg ).

Objective To explore the effect of miR-9 on the expression of NRP1 and its radiation effects in A549 cells.Methods Bioinformatics was used to analyze the potential binding sites of has-miR-9 and NRP1-3'UTR.The miR-9 sequence was inserted into pcDNA-DEST-47 plasmid to construct the eukaryotic expression vector (pcDNA-DEST-miR-9) and to construct the NRP1 gene 3'UTR luciferase reporter plasmid (pEZX-MT05) at the same time.They were simultaneously transferred into A549 cells for analysis of the regulatory effect of miR-9 on the expression of NRP1.Meanwhile miR-29b was used as a negative control to observe whether or not NRP1 gene was a target of miR-9.After 10 Gy irradiation,the expression of NRP1,and the inhibitory effect of miR-9 on it was confirmed by Western blot assay.The expression of miR-9 was detected by real-time PCR.Results It was found that miR-9 reduced the luciferase activity of NRP1-3'UTR wild plasmid (t =3.906,P ＜ 0.05) but not NRP1-3' UTR mutant plasmid.This luciferase activity was not inhibited by other types of miRNA (miR-29b).The expression of NRP1 protein in A549 cells was decreased after the cells were transfected with miR-9 mimic.After irradiation with dose of 10 Gy,the expression of miR-9 were decreased (t =37.319,P ＜ 0.05) and the expression of NRP1 protein were increased.Conclusions miR-9 regulates the expression of NRP1 by targeting 3'UTR site of NRP1 gene in A549 cells.

BACKGROUND:Chronic visceral pain is one of major complaints of irritable bowel syndrome which seriously affects patient’s quality of life. Recent researches have shown that moxibustion therapy has positive effects on aleviating chronic visceral pain in irritable bowel syndrome patients.
OBJECTIVE: To study the clinical utility of moxibustion in coping with chronic visceral pain of irritable bowel syndrome patients, and shed light on the theoretical basis of moxibustion analgesia, thereby to give insights into the further research and application on moxibustion.
METHODS: With the key words of “moxibustion, irritable bowel syndrome, visceral pain, abdominal pain” in Chinese and in English, respectively, a computer-based search was performed in CNKI, VIP, Wanfang and PubMed databases for articles published from January 1990 to October 2014. After the initial screening, the remained articles went through further selection and categorization.
RESULTS AND CONCLUSION:The result shows promising results of moxibustion on relieving chronic visceral pain for both two subtypes of irritable bowel syndrome patients, diarrhea type and constipation type. Moxibustion may exert an analgesic effect on chronic visceral pain in irritable bowel syndrome patients through regulation of visceral hypersensitivity, gastrointestinal motility disorders, brain-gut axis and neuroendocrine system disorders, immune dysfunction and low-grade inflammation in the gut, psychological abnormalities, and alteration of intestinal flora. However, to fuly understand the analgesia effect of moxibustion and elucidate its mechanism, more standardized randomized controled trials employing advanced scientific techniques and equipments wil stil be needed in the future.

Objective To compare the analgesic effect and adverse reactions of oxycodone versus morphine after transcervical resection of adhesions (TCRA). Methods Sixty patients undergoing hysteroscopic TCRA under general anesthesia in Dalian Municipal Woman and Children′s Medical Center were randomly assigned to the test group or control group with 30 patients in each group; the test group received oxycodone 0.1 mg/kg (Q group), and the control group received morphine 0.1 mg/kg (M group). Both group was followed by propofol 2—3 mg/kg, as well as laryngeal mask airway (LMA) insertion after loss of consciousness to maintain ventilation. Propofol 6—10 mg/kg/h and remifentanil 0.1—0.2 μg/kg min were administered intraoperatively to maintain anesthesia. The visual analogue scale (VAS) score, sedation score and number of rescue medications were recorded immediately and 1 h, 2 h after the patient was sent to postoperative recovery room. The incidences of body movement, nausea and vomiting and pruritus after LMA insertion were recorded. Results There were no statistically significant differences between the two groups in VAS score, sedation score ,nausea and vomiting, itchy skin or the number of rescue medications at any post-recovery time point (P > 0.05); the incidence of body movements during LMA insertion was lower in M group: 13.3%(4/30) vs 36.7%(11/30), with statistically significant difference (P < 0.05). Conclusions Oxycodone could provide favorable postoperative analgesia for patients with intrauterine adhesion, with low incidence of adverse reactions.

Objective To investigate the knowledge,attitude and practice of nurses from hospitals in Tibet Autonomous Region on the use of peripheral venous needle and analyze the influencing factors.Methods Utilizing a convenience sampling approach,we conducted a survey from November to December 2023 involving 1 319 nurses from 62 hospitals across 7 cities(regions)of Tibet Autonomous Region.Custom-made electronic questionnaires were utilized.Results A total of 1 320 questionnaires were collected,of which 1 319 were valid,with an effective response rate of 99.92％.The scores of nurses'knowledge,attitude and practice were 46.24±13.68,79.75±10.30,and 60.38±14.15,respectively.808(61.26％)nurses had received relevant training experience.The results of multiple linear regression analysis showed that the influencing factors of nurses'knowledge of peripheral venous indwelling needle included whether they had received training experience,ethnicity,education background,professional title,department and hospital region(P＜0.05).Training experience,ethnicity,educational background,profession title and hospital region were the influence factors of nurses'attitude of venous indwelling needle(P＜0.05).Whether they had received training,ethnicity,education background,department and hospital region were the influencing factors of nurses'practice of peripheral venous indwelling needle(P＜0.05).Conclusion Nurses from hospitals in Tibet Autonomous Region have a good attitude towards using venous indwelling needle.However,the knowledge level is not ideal and the practice is still needed to be improved.Nursing managers should implement targeted training and enrich the training form and content,so as to meet the needs of nurses and to improve the quality of intravenous therapy in the Tibet Autonomous Region.
