BACKGROUND: There have been many significant advances in the diagnosis and treatment of non-small cell lung cancer (NSCLC). However, the mechanism underlying the progression of NSCLC is still not clear. Plant homodomain finger-like domain-containing protein 5A (PHF5A) plays an important role in processes of chromatin remodeling, morphological development of tissues and organs and maintenance of stem cell pluripotency. This study aims to investigate the role of PHF5A in the proliferation and migration of NSCLC. METHODS: A549 and PC-9 PHF5A overexpression cell lines were constructed. PHF5A expression was decreased in H292 and H1299 cells by using siRNA. Flow cytometry was used to detect the cell cycle. MTT assay and clone formation assay were used to examine the proliferative ability of NSCLC, while migration assay and wound healing assay were performed to evaluate the ability of migration. Western blot analysis was used to measure the expressions of PI3K, p-AKT and the associated downstream factors. RESULTS: Up-regulation of PHF5A in A549 and PC-9 cells increased the proliferation rate, while down-regulation of PHF5A in H292 and H1299 cells inhibited the proliferation rate at 24 h, 48 h and 72 h (P<0.05). The metastatic ability was elevated in the PHF5A-overexpresion groups, while reduced in the PHF5A-down-regulation group (P<0.05). In addition, reduced expression of PHF5A induced cell cycle arrest at G1/S phase (P<0.05). Furthermore, decreased expression of PHF5A reduced the expression levels of PI3K, phosphorylation of AKT, c-Myc (P<0.05) and elevated the expression of p21 (P<0.05). CONCLUSIONS These results demonstrated that PHF5A may play an important role in progression of NSCLC by regulating the PI3K/AKT signaling pathway.

OBJECTIV E To in vestigate the situation ，achievements and proble ms of consistency evaluation policy of generic medicines in China. METHODS The descriptive analysis was performed after collecting and sorting out the information of generic medicine passing consistency evaluation （GMPCE） published on the official website of the National Medical Products Administration. The basic information ，the distribution and changes of GMPCE were analyzed statistically in National Essential Medicine List （hereinafter refer to as “essential medicine list ”），Medicine List for National Basic Medical Insurance ，Industrial Injury Insurance and Maternity Insurance （hereinafter refer to as “medical insurance list ”）and the result of the successful selection of centralized medicine procurement organized by the state （hereinafter refer to as “centralized procurement list ”）. RESULTS From 2017 to 2021，415 chemical generic drugs had passed consistency evaluation in China ，including 309 varieties，1 822 specifications， 6 dosage forms ，and 17 pharmacological mechanisms ，basically belonging to 30 provinces，and 492 drug manufacturers （except 12 products had not been found the manufacturers ）；the proportion of GMPCE in essential medicine list increased from 0.96％ in 2012 edition to 25.40％ in 2018 edition；that of GMPCE in medical insurance list increased f rom 2.13％ in 2017 edition to 11.68％ in 2021 edition；in the first 5 batches of centralized procurement list，GMPCE accounted for 81.65％，and the maximum price drop after entering the list was 97.52％. CONCLUSIONS The policy linkage has been achieved with the continual increase of the number of GMPCE and their total amount in three lists in China. The accessibility and affordability of related medicines have been improved with the apparent decrease of the price of those medicines. H owever，total number of GMPCE is a little small，with the higher repetition rate of variety and the low proportion in the three lists ；the guarantee measures of those medicine supply need to be strengthened.

Objective: To observe the improving effect of muscle regions of meridians needling method on the upper limb function in children with cerebral palsy of spastic hemiplegic type. Methods: A total of 100 children with cerebral palsy of spastic hemiplegia type were divided into a treatment group and a control group according to the visiting sequence, with 50 cases in each group. The control group was treated with conventional rehabilitation plus conventional acupuncture treatment. The treatment group was treated with conventional rehabilitation plus muscle regions of meridians needling method. The electromyography (EMG) signal values of triceps brachii and pronator teres were detected before treatment, and 3 months and 6 months after treatment. The clinical efficacy was evaluated by Peabody developmental motor scale-fine motor (PDMS-FM) and fine motor function measure (FMFM). Results: Three and six months after treatment, the EMG signal values of triceps brachii and pronator teres, grasping scores and visual-motor integrated scores of PDMS-FM and the FMFM scores in both groups increased to varying degrees compared with the same group before treatment, and the intra-group differences were all statistically significant (all P<0.05). Six months after treatment, the results of the above three items in the treatment group were all better than those in the control group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Muscle regions of meridians needling method added on the basis of conventional rehabilitation can effectively reduce the muscle tone of upper limb and enhance the muscle strength, and improve the upper limb function in children with cerebral palsy of spastic hemiplegia type. The efficacy is superior to that of the conventional rehabilitation plus conventional acupuncture treatment.

OBJECTIVE: To compare the clinical effect on the joint attention and social communication in children with autism spectrum disorder (ASD) between the combined treatment of acupoint catgut embedding therapy with rehabilitation training and the simple application of rehabilitation training. METHODS: A total of 60 children with ASD were randomized into an observation group and a control group, 30 cases in each one. In the control group, the routine ASD rehabilitation training was adopted, including conductive education, speech training and music therapy, once a day. In the observation group, on the base of the treatment as the control group, the catgut embedding therapy was applied to Shenting (GV 24), Baihui (GV 20), Shenmen (HT 7) and the optic area (the point of scalp acupuncture), once a week. In the two groups, the treatment for 4 weeks was as one course, at the interval of 1 week between the courses. A total of 3 courses of treatment were required. The social domain of the autism treatment evaluation checklist (ATEC) and the autism behavior checklist (ABC) were adopted to assess the therapeutic effect of the two groups. RESULTS: After treatment, the scores of each item of the social domain in ATEC and the scores of ABC (feeling, communication, physical movement, language and healthy behavior) were all lower than those before treatment in the two groups (<0.01). The scores of each item in the observation group were lower than those in the control group after treatment (<0.05). CONCLUSION The combined treatment of acupoint catgut embedding therapy with the rehabilitation training effectively improves in the joint attention and social communication. The therapeutic effect of this combined treatment is better than the simple application of rehabilitation training.

BACKGROUND: Spinal cord injury (SCI) is a worldwide medical concern. This study aimed to elucidate the mechanism underlying the protective effect of hyperbaric oxygen (HBO) against SCI-induced neurologic defects in rats via exploring the stromal cell-derived factor-1 (SDF-1)/CXC chemokine receptor 4 (CXCR4) axis and expression of brain-derived neurotrophic factor (BDNF). METHODS: An acute SCI rat model was established in Sprague-Dawley rats using the Allen method. Sixty rats were divided into four groups (n = 15 in each group): sham-operated, SCI, SCI treated with HBO (SCI + HBO), and SCI treated with both HBO and AMD3100 (an antagonist of CXCR4; SCI + HBO + AMD) groups. The rats were treated with HBO twice a day for 3 days and thereafter once a day after the surgery for up to 28 days. Following the surgery, neurologic assessments were performed with the Basso-Bettie-Bresnahan (BBB) scoring system on postoperative day (POD) 7, 14, 21, and 28. Spinal cord tissues were harvested to assess the expression of SDF-1, CXCR4, and BDNF at mRNA and protein levels, using quantitative real-time polymerase chain reaction, Western blot analysis, and histopathologic analysis. RESULTS: HBO treatment recovered SCI-induced descent of BBB scores on POD 14, (1.25 ± 0.75 vs. 1.03 ± 0.66, P < 0.05), 21 (5.27 ± 0.89 vs. 2.56 ± 1.24, P < 0.05), and 28 (11.35 ± 0.56 vs. 4.23 ± 1.20, P < 0.05) compared with the SCI group. Significant differences were found in the mRNA levels of SDF-1 (mRNA: day 21, SCI + HBO vs. SCI + HBO + AMD, 2.89 ± 1.60 vs. 1.56 ± 0.98, P < 0.05), CXCR4 (mRNA: day 7, SCI + HBO vs. SCI, 2.99 ± 1.60 vs.1.31 ± 0.98, P < 0.05; day 14, SCI + HBO vs. SCI + HBO + AMD, 4.18 ± 1.60 vs. 0.80 ± 0.34, P < 0.05; day 21, SCI + HBO vs. SCI, 2.10 ± 1.01 vs.1.15 ± 0.03, P < 0.05), and BDNF (mRNA: day 7, SCI + HBO vs. SCI, 3.04 ± 0.41 vs. 2.75 ± 0.31, P < 0.05; day 14, SCI + HBO vs. SCI, 3.88 ± 1.59 vs. 1.11 ± 0.40, P < 0.05), indicating the involvement of SDF-1/CXCR4 axis in the protective effect of HBO. CONCLUSIONS HBO might promote the recovery of neurologic function after SCI in rats via activating the SDF-1/CXCR4 axis and promoting BDNF expression.

BACKGROUND: As a special source of stem cells, dental pulp stem cells (DPSCs) make much progress in the development of tissue engineering field due to their high proliferation and self-renewal ability. In the certain conditions DPSCs can be induced to differentiate into a variety of specialized tissue cells, providing a new way for tissue engineering development. OBJECTIVE: To review the main progress in the DPSCs biological characteristics, original source, isolation method, and its related application in tissue engineering research. METHODS: "Dental pulp stem cell, differentiation, regenerative medicine, tissue engineering" in English and Chinese were termed as the keywords to search relevant articles about DPSCs and tissue engineering published from 2005 to 2017 in PubMed, Medline, WanFang, and CNKI databases. After removal of repetitive or irrelevant articles, 66 articles were finally reviewed. RESULTS AND CONCLUSION: With the development of tissue engineering and regenerative medicine, the effective combination of DPSCs and tissue engineering scaffolds have be further achieved. Recent studies on DPSCs focus on the properties of DPSCs differentiating into odontoblasts and osteocytes/osteoblasts and on the potential of nerve repair, vascular remodeling, corneal reconstruction and chondrogenic differentiation.

In order to explore the effect of abendazole sulfoxide-loaded thermo-sensitive hydrogel (ABZSO/PLGA-PEG-PL-GA) on alveolar hydatid cysts,the viable protoscoleces incubated in vitro with ABZSO/PLGA-PEG-PLGA (20,40,80 μg/mL),ABZSO (40 μg/mL),PLGA-PEG-PLGA and the blank control,respectively,and the viable protoscoleces were counted.The morphological of the alveolar hydatid cysts or protoscoleces in each group were observed by scanning electron microscop(SEM).After the rats infected with alveolar hydatid cysts having been treated,the sizes of the alveolar hydatid cysts were observed.When the alveolar hydatid cysts incubated in different drug group in 18 days,the percentage of viable protoscoleces in ABZSO/PLGA-PEG-PLGA (40μg/mL) group was lower than that of ABZSO (40 μg/mL) group.Results of SEM showed that the protoscoleces in the ABZSO/PLGA-PEG-PLGA (80 μg/mL) group were seriously damaged.The in vivo study demonstrated the anti-alveolar hydatid cysts efficacy of ABZSO/PLGA-PEG-PLGA (4 mg/mL) group was better than the other groups.The anti-alveolar hydatid cysts efficacy of ABZSO/PLGA-PEG-PLGA is evident.

Objective:To observe the clinical efficacy of needling thirteen ghost acupoints for children with autism spectrum disorder. Methods:A total of 90 cases with autism spectrum disorder (ASD) aged between 2 and 6 years were randomly allocated into 2 groups by random number table. The control group (n=45) received routine rehabilitative training, and the treatment group (n=45) received acupuncture at thirteen ghost acupoints plus routine rehabilitative training. The Beijing Gesell developmental (Gesell) scale and autism behavior checklist (ABC) were used to assess the intellectual, language and behavior development before and 3 months after the treatment. Results:After the treatment, the total effective rate in the treatment group was 82.2%, versus 55.6% in the control group, showing a statistical significance (P<0.05). As for the scores of social, emotional and language in Gesell scale, there were significant intra-group differences in the treatment group (allP<0.05), and all the five subscales in the Gesell scale in the treatment group were significantly better than those in the control group (allP<0.05). As for the scores of ABC, there were significant intra-group differences in the treatment group (P<0.05), and the scores in the treatment group were significantly better than those in the control group (allP<0.05). Conclusion: Rehabilitation training plus acupuncture at thirteen ghost acupoints can significantly improve the intellectual, language and abnormal behavior in autism spectrum disorder children.

Objective To analyze the cost-effectiveness of hospital rehabilitation and hospital-family rehabilitation in children with cere-bral palsy. Methods From January to December, 2016, 60 cases of children aged one to three years with cerebral palsy were divided into hospital rehabilitation group and hospital-family rehabilitation group, with 30 cases in each group. The hospital rehabilitation group received rehabilitation of traditional Chinese and Western medicine treatment, including exercise therapy, physical therapy and Chinese Medical ther-apy; while the hospital-family rehabilitation group received family rehabilitation. The Gross Motor Function Measure (GMFM) and Pea-body Developmental Motor Scale-fine Motor (PDMS-FM) were used to evaluate the motor function and fine motor function before and af-ter treatment. Results The GMFM score was higher (t=5.333, P<0.001), and the total medical cost was higher (t=23.614, P<0.001) in the hospital rehabilitation group than in the hospital-family rehabilitation group. However, the cost of medical care was significantly lower for every 1-point increase in GMFM and visual-motion integration of PDMS-FM in the hospital rehabilitation group than in the hospital-family rehabilitation group (t>2.065, P<0.05). Conclusion The hospital rehabilitation model may be a more economical and effective treatment for younger age children with cerebral palsy, and the hospital-family rehabilitation model could be used as an effective complementary rehabili-tation model for this age group.
