OBJECTIVE: To synthetize the synthesis of mitoxantrone and evaluate its quality. METHODS: Crude product of mitoxantrone was prepared by slow oxidation of 1,4,5,8-tetrahydro-anthraquinone with N-(2-hydroxyethyl) ethylenediamine in water bath at 50 ℃ for 2 h under argon protection and in dry air for 4 h. The crude product was crystallized by ethanol-n-hexane (4 ∶ 1,V/V) mixture solution, which was cooled overnight and then washed by ethanol-n-hexane mixture for many times. The melting range, pH value of solution, ultraviolet-visible absorption spectrum, infrared structural characteristics, drying weight loss (water loss rate) and critical relative humidity (CRH) of the purified products (4 batches) were investigated. HPLC method was used to determine the contents of mitoxantrone. RESULTS: The mitoxantrone was prepared successfully, and synthetic yield of mitoxantrone was 34.3%; the melting point ranged from 159.1-163.6 ℃. The aqueous solution was alkaline (pH 7.63-9.54); there was a maximum ultraviolet absorption peak at 235-245 nm; there was a maximum absorption peak of visible light at 590-600 nm; the infrared characteristics were consistent with those described of mitoxantrone in the 2015 edition of the Infrared Spectrum Collection of Drugs; water loss rate were -0.83%-2.36%; CRH value was 54.7%, and the average content of the product was 78.1%(n=4) by HPLC method. CONCLUSIONS: The mitoxantrone is synthesized under mild, non-toxic and harmless experiment conditions. The synthesis step is simple, the cost is low and the yield is high. The quality of products meets the quality requirements.

Objective:
To understand the current situation of college students emotional regulation and its correlation with perceived social support, so as to provide a reference for improving emotional regulation ability among college students.
Methods:
From September 15 to October 15, 2022, a total of 15 560 students from 27 colleges and universities in Guangdong, Jiangsu, Shandong, Shanghai, Anhui, Hebei, Yunnan, Shanxi and Gansu were enrolled by stratified random sampling method. The Perceived Social Support Scale (PSSS) and the Emotion Regulation Questionnaire (ERQ) were used to investigate, and multiple stepwise regression was used to explore the relationship between perceived social support and emotion regulation of college students.
Results:
The scores of emotion regulation, cognitive reappraisal and expression inhibition were 44(40, 50), 24(20, 28) and 20(19, 24) respectively. There were significant differences in the scores of emotion regulation, cognitive reappraisal and expression inhibition by age, grade, household registration, only child status,cost of living, and sleep ( H/Z =77.72, 49.73, -5.10, -9.77, 7.68, 168.27 ; 204.55, 317.32, -5.96, -7.60, 131.20, 968.08; 82.18, 148.04, -2.30, -8.03, 64.82, 188.08, P <0.05). In addition, the multiple stepwise regression found that family support, friend support, and other support in perceived social support all had a positive impact on the emotional regulation state of college students ( β =0.137,0.207,0.090), and family support and friend support had a significant positive effect on expression inhibition( β =0.079,0.053) and cognitive reappraisal( β =0.153,0.296)( P <0.01).
Conclusion
The perceived social support can directly affect the emotional regulation of college students, and improving the emotional regulation ability has a positive significance to promote the mental health level among college students.

In this study, we used a rat model of pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT) to investigate the role and mechanism of angiotensin (Ang)-(1-7) in regulating pulmonary artery diastolic function. Three weeks after subcutaneous injection of MCT or normal saline, the right ventricular systolic pressure (RVSP) and right ventricular hypertrophy index (RVHI) of rats were detected using a right heart catheter. Vascular endothelium-dependent relaxation was evaluated by acetylcholine (ACh)-induced vasodilation. The relaxation function of vascular smooth muscle was evaluated by sodium nitroprusside (SNP)-induced vasodilation. Human pulmonary artery endothelial cells (HPAECs) were incubated with Ang-(1-7) to measure nitric oxide (NO) release levels. The results showed that compared with control rats, RVSP and RVHI were significantly increased in the MCT-PAH rats, and both ACh or SNP-induced vasodilation were worsened. Incubation of pulmonary artery of MCT-PAH rats with Ang-(1-7) (1 × 10-9-1 × 10-4 mol/L) caused significant vaso-relaxation. Pre-incubation of Ang-(1-7) in the pulmonary artery of MCT-PAH rats significantly improved ACh-induced endothelium-dependent relaxation, but had no significant effect on SNP-induced endothelium-independent relaxation. In addition, Ang-(1-7) treatment significantly increased NO levels in HPAECs. The Mas receptor antagonist A-779 inhibited the effects of Ang-(1-7) on endothelium-dependent relaxation and NO release from endothelial cells. The above results demonstrate that Ang-(1-7) promotes the release of NO from endothelial cells by activating Mas receptor, thereby improving the endothelium-dependent relaxation function of PAH pulmonary arteries.

OBJECTIVE:
To compare the clinical efficacy on cervical spondylosis of nerve root type with qi stagnation and blood stasis treated with warming needle with different lengths of moxa stick.
METHODS:
Six hundred patients with cervical spondylosis of nerve root type with qi stagnation and blood stasis were randomly divided into 4 groups: a 4 cm length group (150 cases, 5 cases dropped off, 2 cases suspended), a 3 cm length group (150 cases, 6 cases dropped off, 2 cases suspended), a 2 cm length group (150 cases, 6 cases dropped off), and a routine acupuncture group (150 cases, 6 cases dropped off). Warming needle with moxa stick in the length of 4 cm, 3 cm and 2 cm was delivered in the 4 cm length group, the 3 cm length group and the 2 cm length group, respectively. In the routine acupuncture group, simple acupuncture was applied. The acupoints selected in the above groups included Dazhui (GV 14) and bilateral Jiaji (EX-B 2) of C5 and C7, Fengchi (GB 20), Jianzhen (SI 9), Quchi (LI 11), Zhongzhu (TE 3), etc. In each group, the intervention was delivered once daily and 5 times a week. One course of intervention was composed of 2 weeks and 2 courses were required. The TCM syndrome score, the score of clinical assessment scale for cervical spondylosis (CASCS), the score of the brachial plexus traction test of the affected upper limb, F wave occurrence rate and conduction velocity of the ulnar nerve, the median nerve and the radial nerve of the affected upper limb were compared before and after treatment in the patients of each group. The levels of serum inflammatory factors, i.e. interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor α (TNF-α) and hypersensitive C-reactive protein (hs-CRP), were measured before and after treatment in the patients of each group. The clinical cfficacy was evaluated in the 4 groups.
RESULTS:
After treatment, the results of TCM syndrome evaluation, i.e. the scores of neck pain, activity limitation and upper limb numbness and pain, as well as the total scores; and the scores of brachial plexus traction test were reduced when compared with those before treatment in each group (P<0.01, P<0.05). The scores of subjective symptoms and adaptability, and the total scores of CASCS were elevated in comparison with those before treatment in each group (P<0.01, P<0.05). In the 4 cm length group, compared with the other 3 groups, the scores of neck pain and activity limitation for TCM syndrome evaluation, and its total score were lower (P<0.05, P<0.01); and the scores of subjective symptoms and adaptability, and the total score of CASCS were higher (P<0.05, P<0.01). The score of the brachial plexus traction test in the 4 cm length group was lower than that of the routine acupuncture group (P<0.05). After treatment, F wave occurrence rates and conduction velocity of median nerve and radial nerve were increased when compared with those before treatment in each group (P<0.05, P<0.01). F wave occurrence rate and conduction velocity of the radial nerve in the 4 cm length group were higher than those of the other 3 groups (P<0.05), and those of the median nerve were higher when compared with the routine acupuncture group (P<0.05). After treatment, the levels of serum IL-1β, IL-6 and TNF-α were all reduced when compared with those before treatment in each group (P<0.01, P<0.05); the level of serum IL-6 in the 4 cm length group was lower than those of the other 3 groups and serum level of TNF-α was lower compared with that in the routine acupuncture group (P<0.05). The total effective rate of the 4 cm length group was 78.3% (112/143), which was higher when compared with the 3 cm length group (67.6%, 96/142), the 2 cm length group (65.3%, 94/144) and the routine acupuncture group (53.5%, 77/144), respectively (P<0.05).
CONCLUSION
Warming needle with moxa stick of 4 cm in length effectively relieves the clinical symptoms of cervical spondylosis of nerve root type with qi stagnation and blood stasis, improves the nerve function of the upper limbs, and reduces the inflammatory responses caused by nerve compression. The clinical efficacy of this therapy with moxa stick of 4 cm in length is superior to the warming needle with moxa sticks of 3 cm and 2 cm, as well as the routine acupuncture.

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 investigate the situation and existing problems of the naming of commercially available Chinese patent medicine (CPM) in China, and to put forward the improvement suggestions. METHODS: Announced in Dec. 31, 2017 by CFDA, there were totally 169 601 kinds of national coded drugs. Total of 35 513 kinds of CPM with drug approval number “Z” and 68 kinds of imported CPM with importing registration certificates “Z” was screened by using Excel 2013 software. Based on Naming Technical Guidelines for Generic Name of Chinese Patent Medicines (hereinafter referred to as the Guidelines), the unqualified situation of domestic CPM were summarized, and unqualified domestic Chinese patent medicine were analyzed statistically in respects of dosage form, special population medication and area. RESULTS: There were 5 091 kinds of drugs named nonconformity with the “Guidelines”, accounting for 14.34% of domestic CPM. The problems of naming mainly focused on exaggerated naming (1 723 kinds, 33.84%), dosage form un-located after naming (1 118 kinds, 21.96%), naming by endangered protected animals and plants (851 kinds, 16.72%), naming by pharmacology and other related terms (848 kinds, 16.66%). Names emboding “traditional cultural features” (1 324 kinds, 4.35%) took the lower proportion. Top 5 dosage forms of domestic CPM with unqualified naming were tablets (1 203 kinds, 23.63%), capsules (821 kinds, 16.13%), mixture (802 kinds, 15.75%), pills (706 kinds, 13.87%), granules (448 kinds, 8.80%). The problems of special population medication for domestic CPM with unqualified naming concentrated on children’s medication (608 kinds, 11.94%). The main manufacturers of domestic CPM with unqualified naming came from Guangdong (613 kinds, 12.04%), Guangxi Zhuang Autonomous Region (371 kinds, 7.29%), Jilin (265 kinds, 5.21%), Shaanxi (245 kinds, 4.81%) and Beijing (233 kinds, 4.58%). CONCLUSIONS: There are many problems in naming of commercially available domestic CPM in China, mainly reflecting as naming type, dosage form, pediatric drugs, etc. There are fewer names emboding “traditional cultural features”. It is suggested that we should further standardize the naming of CPM by strengthening and perfecting the management and examination system of CPM, highlighting the naming principles of Chinese traditional culture and protecting traditional classical brands.

Objective To understand the epidemiological characteristics of scrub typhus disease and to provide a scientific basis for the prevention and control of scrub typhus disease. Methods Descriptive epidemiological methods were used to analyze the population and regional distribution of scrub typhus. Seasonal characteristics were analyzed using concentration method and circular distribution method, and incidence trend was analyzed using joinpoint regression model. Results The annual incidence rate of scrub typhus was 0.95/100 000 from 2010 to 2022. The incidence rate of male was 0.77/100 000, lower than that of female 1.12/100 000 (χ2=18.89, P<0.05). The incidence rate of the 60-74 years old group was 3.38/100,000, and the total number of cases in the age group 45-74 years was 416 (74.95%). Occupational distribution was mainly among farmers, with 448 cases (80.72%). The top three regions with the highest number of reported cases (in order: Donghai County, Ganyu District, and Guannan County) reported a total of 416 cases, accounting for 74.95%. Concentration ratio was M=0.9408, and the incidence of scrub typhus disease was strictly seasonal. Circular distribution results showed a-=-62.3728, S=20.8960. The circular distribution results indicated that the peak day was October 19th, and the peak period was between October 7 to December 19. The average annual percentage change (AAPC) of the incidence rate from 2010 to 2022 was 13.70%, 95% CI (-8.62%~41.48%), and the incidence rate showed an upward trend (t=1.15, P=0.249). Conclusion The incidence of scrub typhus disease is strictly seasonal, and the incidence rate over the years shows an upward trend. It is necessary to strengthen monitoring and take various intervention measures to reduce the risk of scrub typhus disease.
