Roasting is a characteristic traditional Chinese medicine(TCM)processing technology, which has a long history. A large number of ancient books recorded the varieties and processing methods of roasted TCM. However, with the evolution of the times, there are relatively few studies on this processing technology in modern times. By consulting works related to herbs of the past, this study collected a total of 119 kinds of TCM roasting methods recorded in 123 ancient books and systematically summarized the historical evolution and development of TCM roasting methods. At the same time, the inclusion of roasted varieties in Chinese Pharmacopoeia of different editions, National Traditional Chinese Medicine Processing Specification(1988 edition), and provincial TCM processing specifications was sorted out. This paper reviews the research progress of the process, quality control, chemical composition, pharmacological action, and clinical application of roasted TCM and analyzes the evolution of the roasting technology, in order to provide a literature basis for optimizing roasting process parameters, establishing the quality standard of roasted decoction pieces, explaining the processing theory of roasting, and promoting rational clinical application.

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.

Self-sampling is a method by which the subject collects the own specimens for disease detection. It has the advantages of strong privacy, convenient and simple operation, free time and place, etc. It can improve the compliance of people in remote areas, affected by traditional concepts, limited by working hours and underdeveloped transportation and medical treatment to participate in disease detection and screening. With the development of "Internet+health care" and "Internet+nursing service", home-based self-sampling testing will become a developing situation for disease detection and screening. Human immunodeficiency virus and Human papillomavirus infection bring a heavy burden to individuals and society. In the absence of effective and widespread primary prevention, secondary prevention, namely "early detection, early diagnosis and early treatment" is an effective measure to control the adverse consequences. At present, there are many researches on HPV and HIV self-sampling test, whose test results are highly reliable and highly accepted in the population, and is of great significance for improving the coverage rate of cervical cancer screening and the diagnosis rate of HIV carriers.

OBJECTIVE: To build bridges between anti-α enolase antibody (anti-enolase 1 antibody, anti-ENO1 antibody) and common clinical and laboratory characteristics of systemic lupus erythematosus (SLE) and to analyze the role of anti-ENO1 antibody in the evaluation of SLE disease activity. METHODS: The SLE patients with retinopathy and without retinopathy were enrolled in the study, as well as healthy individuals whose gender and age matched with those of the SLE patients. Serum anti-ENO1 antibodies were measured using enzyme-linked immunosorbent assay (ELISA), presenting as intra-group positive rate and arbitrary units (AU) value. Clinical and laboratory data were obtained from medical records. RESULTS: The SLE retinopathy patients represented various fundus abnormalities. Ranked by percentage, the top three retinopathies were retinal hemorrhage (14/32, 43.75%), cotton-wool spots (8/32, 25.00%) and retinal vein occlusion (3/32, 9.38%). Among the 32 SLE retinopathy patients, 13 (40.63%) suffered from two or more fundus abnormalities. The positive rate and AU value of the SLE patients were higher than of the SLE patients without retinopathy (68.75% vs. 46.00%, P=0.043; 16.11%±10.35% vs. 12.06%±6.47%, P=0.045). Besides, the positive rate and AU value of the two SLE groups were both significantly higher than those of the healthy control group (P < 0.001). Compared with the SLE-without-retinopathy group, the systemic lupus erythematosus disease activity index (SLEDAI)-2000 of the SLE retinopathy patients were significantly higher than those of the SLE patients without retinopathy (17.41±4.25 vs. 9.48±5.35, P < 0.001). Dividing all the SLE patients into an anti-ENO1-positive group and an anti-ENO1-negative group, we found that anti-ENO1-positive was more likely to be correlated to developing fever and positive result of urine occult blood (P=0.011, P=0.042). Comparing with the patients with negative anti-ENO1 antibodies, the patients with positive anti-ENO1 antibodies had significantly higher erythrocyte sedimentation rate (ESR) [the median (range) was 29.50 (1.52-110.00) mg/L vs. 12.00 (4.00-101.00) mg/L, P=0.001], higher immunoglobulin G (IgG) [the median (range) was 14.30 (4.02-37.80) g/L vs. 10.46 (2.50-25.73) g/L, P=0.000 3], and higher blood platelet count (PLT) [(205.87×10⁹±67.98×10⁹) /L vs. (164.57×10⁹±69.57×10⁹) /L, P=0.008], as well as higher immunoglobulin A (IgA) [the median (range) was 2.85 (0.07-27.00) g/L vs. 2.05 (0.42-4.36) g/L, P=0.014]. CONCLUSION The positive rate and AU value of anti-ENO1 antibody suggested higher SLE disease activity and they were elevated in SLE and SLE retinopathy.

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

Objective:To systematically quantify the access to screening and surveillance service of liver cancer in populations in China, especially a series of sub-indicators of the availability.Methods:Following the specific indicators applied by the International Agency for Research on Cancer in the session of availability and use of screening practices in several cancer screening handbooks, information about the access/availability of liver cancer screening and surveillance in population in China were collected; the indicators included local policies and guidelines, procedures most commonly used or recommended, population coverage and participation rate, compliance and related factors, treatment rate, acceptability, equity and others. Systematic review approach was used, combined with searching core literatures/monograph, websites of governments and available program reports, for a systematic analysis on the access to liver cancer screening and surveillance in populations in China.Results:A total of 34 journal articles were included from the systematic review and most of which were about the participation of secondary liver screening or surveillance compliance; additional information were mainly obtained from the other sources. Overall, there were clearly recommended screening and surveillance procedures for liver cancer in the three major cancer screening programs funded by the central government of China. It was estimated that 0.09% of the population aged 35-74 years were covered by liver cancer screening in 2019 in China. The overall participation rates of secondary screening ranged from 37.5% to 62.3% in three major programs, the median compliance rate of surveillance was reported as 26.9% ( Q1, Q3: 23.5%, 41.0%) in the 6 included studies. Two studies reported the factors affecting the participation and compliance. A large-scale multicenter analysis showed that the subject acceptability to alpha fetoprotein test combined with ultrasound screening was as high as 99.3% in high-risk population in urban area. The treatment rate of liver cancer founded by screening, surveillance or follow-up was estimated to be >90% in rural population. No studies of equity were obtained via the systematic review. Conclusions:The public health service programs in China all recommend specific procedures for liver cancer screening in general population and surveillance for high-risk individuals. However, the overall availability needs to be improved, particularly in the indicator of population coverage. Participation rates of screening and compliance rates of surveillance varied among the included programs and the studies, suggesting that the influencing factors need to be further identified. The relatively high subject acceptability suggests the potential demands for screening service. More efforts are needed to address the access to screening and surveillance of liver cancer in populations in China.

Objective:To evaluate the safety and efficacy of Toumai ? endoscopic robotic system in radical prostatectomy. Methods:This study was a single-center phase Ⅲ randomized controlled study. From June 2020 to January 2021, patients with prostate cancer who met the inclusion criteria in Changhai Hospital Affiliated to Naval Military Medical University were divided into the experimental group and the control group by random table method. Inclusion criteria included aged 18 to 80 years, pathologically diagnosed as prostate cancer, clinical stage ≤T 2N 0M 0. Exclusion criteria included patients requiring emergency surgery, having serious cardiovascular diseases and cannot tolerate surgery, having participated in other investigational drug or device clinical trials within the last 3 months. The experimental group used Toumai ? laparoscopic robotic system, and the continence group used the Da Vinci robotic system. The patients in both groups underwent radical prostatectomy via a transabdominal approach, which was performed by two surgeons. The clinical characteristics between the two groups were compared, related adverse events were recorded, and PSA and urinary continence were followed up one month after the operation. Results:A total of 44 patients were enrolled in this study, including 22 cases in the experimental group and 22 cases in the control group. The mean age of patients in the trial group and the control group was (67.7±7.5) years and (66.4±6.3) years, respectively. The median PSA at diagnosis was 10.5 (7.7, 23.7) ng/ ml and 13.5 (8.9, 24.7) ng/ ml, respectively. Biopsy Gleason score of 6, 7, 8 and 9 in experimental group were 13.6% (3/22), 68.2% (15/22), 4.5% (1/22) and 13.6% (3/22), respectively, and in the control group were 4.5% (1/22), 59.1% (13/22), 22.7% (5/22) and 13.6% (3/22) respectively. The middle risk and high risk group in the experimental group was 50.0% (11/22), 50.0% (11/22), and the control group was 36.4% (8/22), 63.6% (14/22). There was no statistical difference between the two groups.The operations in both groups were successfully performed. There were no conversions to open or laparoscopic surgeries, and no Clavien-Dindo grade Ⅲcomplications. There was no significant difference in the estimated blood loss during the operation [(109.1±51.6)ml vs.(94.5±51.6)ml] and the blood transfusion rate [9.1%(2/22)vs. 4.5%(1/22)] in both groups. The operation time was significantly higher in the experimental group than that in the control group [164.5(130.5, 214.3) min vs. 88.0(65.3, 110.5)min, P<0.001]. The positive rate of surgical margin was 13.6% (3/22) in the experimental group and 36.4% (8/22) in the control group, respectively, showing no significant difference. The pathologic stages of pT 2, pT 3a and pT 3bin experimental group were 63.6% (14/22), 13.6% (3/22) and 22.7% (5/22), respectively, while those in control group were 36.3% (8/22), 40.9% (9/22) and 22.7% (5/22), respectively, showing no significant difference. The recovery rates of urine control in the experimental group and the control group were 22.7% (5/22) and 22.7% (5/22), respectively. The median PSA in the experimental group and the control group were 0.055 (0.021, 0.103) ng/ ml and 0.032 (0.010, 0.089) ng/ ml, respectively, with no statistical difference. Conclusions:The Toumai ? endoscopic robotic system can successfully perform radical prostatectomy, based on insignificant difference from Da Vinci robotic system in safety and efficacy. The short-term follow-up showed that tumor control and urinary continence have recovered well in the test group. The long-term effect of the new system on tumor control and functional recovery after radical prostatectomy needs further multi-center studies.

To explore the genetic causes of 3 male infertility patients with acephalospermia and the outcome of assisted reproductive technology. Clinical diagnosis, sperm morphology examination, sperm transmission electron microscopy examination were performed on 3 patients, and the whole exome sequencing technology was used for screening, Sanger sequencing verification, mutation pathogenicity analysis, and protein sequence homology comparison. Assisted reproductive technology was implemented to assist pregnancy treatment. The 3 patients were all sporadic infertile men, aged 25, 42 and 26 years, and there was no obvious abnormality in the general physical examination. Male external genitalia developed normally, bilateral testicles were normal in volume, and bilateral epididymis and spermatic vein were palpated without nodules, cysts, and tenderness. Repeated semen analysis showed that a large number of immature sperm could be seen, and they had the ability to move. The SUN5 gene of the 3 male infertile patients was a case of homozygous missense mutation c.7C>T (p.Arg3Trp), a case of compound heterozygous missense mutation c.1067G>A (p.Arg356His) and nonsense mutation c.216G>A (p.Trp72*) and a case of homozygous missense mutation c.1043A>T (p.Asn348Ile), of which c.7C>T (p.Arg3Trp) and c.1067G>A (p.Arg356His) were new variants that had not been reported. SIFT, Mutation Taster and PolyPhen-2 software function prediction results were all harmful, the nonsense mutation c.216G>A (p.Trp72*) led to the premature termination of peptide chain synthesis which might have a greater impact on protein function. The homology regions in the protein sequence homology alignment were all highly conserved.The 3 male patients and their spouses obtained 4 biological offspring through intracytoplasmic sperm injection, all of which were boys, and one of them was a twin.Three male infertile patients might be caused by SUN5 gene mutations. Such patients could obtain their biological offspring through assisted reproductive technology. It was still necessary to pay attention to the genetic risk of ASS, it was recommended that both men and women conduct genetic counseling and screening at the same time. In clinical diagnosis, whole exome sequencing technology could be used to perform auxiliary examinations to determine the treatment plan and assisted reproductive methods as soon as possible to reduce the burden on the family and society. The newly discovered mutation sites of SUN5 gene provided clues and directions for elucidating the pathogenic mechanism, and at the same time expanded the pathogenic mutation spectrum of ASS.
