Objective:To study the application of herbs of National TCM Master Li Jiren on treating atrophy with deficiency syndrome. Methods:By collecting 195 cases of atrophy-disease treated by Professor Li in Out-patient Medical Record System dated from January 2013 to December 2018, and FP-Growth computing paradigm was used to analyze frequency, FP-Growth enhanced computing paradigm was used to analyze the frequencyand association of symptoms and herbal pairs. Professor Li’s experience was accordingly summurized with clinic situation and Traditional Chinese Medicine theory. Results:There are 121 main symptoms among 195 selected cases, and amyotrophy (79 times), decreased muscle strength (69 times), difficulty in walking (52 times), weakness of upper extremities (43 times) and poor sleeping quality (33 times) rank the top 5 symptom. In terms of tongue manifestations, the color pink, pale, red and purple are the most; while in terms of pulses, weak, thread, deep and stringy were frequent. A total of 159 sorts of herbs were collected and Astragali Radix (140 times), Angelicae Sinensis Radix (103 times), Cistanches Herba (93 times), Psoraleae Fructus (87 times), Morindae Officinalis Radix (81 times) were the top 5. The herbs used are mainly with the function of tonifying deficiency, dispelling wind and dampness promoting blood circulation and removing blood stasisand. most of the herbs belong to liver, kidney and spleen meridians with warm character, sweet and bitter in taste. Association analysis between high-frequency herbs indicated that Astragali Radix is the core of most formulas, which conformed to Li’ s clinical experience. Three prescriptions were also obtained through cluster analysis. Conclusion:Professor Li treated atrophy diseases with deficiency syndrome by the unique idea of strengthening primordial qi and consolidating body resistance of Xin’an Medicine school. On the ground of using herbs to tonify, synergy of herbs, which were able todispel pathogenic wind, dredge channels and promote blood circulation for removing blood stasis, was achieved based on differentiation.

The 13th five-year plan pointed out clearly that it is necessary to implement food safety strategy , and form a manage-ment system for strict and efficient social co-governance of food safety .The paper introduced the practice and the results of food safety co-governance in Yunnan province , and provided some proposals with the purpose to help the development of food safety co -governance work in the other areas .

Food and drug supervision is a specialized job. However, the present supervisors coming from various departments have differences in supervision concepts, professional background, knowledge structure and work experience, which shows large gap with the requirements of supervision work. Therefore, it is urgent to strengthen the classified training for the improvement of quality construction and specialization. The article provided the curriculum system, teaching explanation and ideas about the classified training for all supervisors in the whole system, which may be beneficial to the training of food and drug supervisors.

After the structural reform in the food and drug supervision system, the knowledge structure and the professional re-quirements of the supervisors is unmatched, which hinder the fulfillment of regulatory responsibilities and the performance of adminis-trative efficacy. Effective ways for team building are actively explored throughout the country. The paper introduced the adult corre-spondence education of the supervisors in Zhejiang Ningbo food and drug supervision system to provide a good example for training work throughout the country and some useful suggestions for the quality improvement of the supervision team.

Objective:To evaluate the influencing factors of carotid-femoral pulse wave velocity (CF-PWV) and its value to predict outcomes in peritoneal dialysis (PD) patients.Methods:Eligible patients undergoing PD in Renji Hospital of Shanghai Jiao Tong University between August 2016 and July 2018 were recruited and prospectively followed up until death, PD cessation, or to the end of the study. CF-PWV was measured by an arterial pulse wave velocity meter to assess arterial stiffness (July 31, 2020). Overhydration was measured by bioimpedance spectroscopy. The patients were divided into CF-PWV≤10 m/s group and CF-PWV>10 m/s group according to the measured value of CF-PWV. The influencing factors of elevated CF-PWV were analyzed by multivariate logistic regression. Survival curves were generated using the Kaplan-Meier method and multivariate Cox proportional hazards models were used to analyze the difference for all-cause mortality and cardiovascular disease (CVD) mortality between the two groups.Results:A total of 224 PD patients were enrolled, including 133 males (59.4%). The age was (55.2±13.4) years old, and median PD vintage was 22.3(6.5, 59.3) months. Among them, 47(21.0%) patients were comorbid with diabetes, and 37(16.5%) patients had CVD history. The median CF-PWV was 9.6(8.4, 11.4) m/s for the cohort, and 105(46.9%) participants had CF-PWV over 10 m/s. Compared with CF-PWV≤10 m/s group, CF-PWV>10 m/s group patients had older age, increased percentage of diabetes and CVD (all P<0.05). Multivariate logistic analysis showed that increased age ( OR=1.070, 95% CI 1.043-1.099, P<0.001), diabetes ( OR=3.693, 95% CI 1.646-8.287, P=0.002) and higher overhydration ( OR=1.238, 95% CI 1.034-1.483, P=0.020) were independent influencing factors for elevated CF-PWV in PD patients. After followed up for 37.4(25.6, 41.7) months, 24 patients died, including 19 cases of CVD-related deaths. Kaplan-Meier survival analysis showed that all-cause mortality and CVD mortality were significantly higher in the CF-PWV>10 m/s group than those in CF-PWV≤10 m/s group (Log-rank χ2=6.423, P=0.011; Log-rank χ2=6.243, P=0.012, respectively). Multivariate Cox proportional hazards models showed that increased age was an independent influencing factor for both all-cause mortality and CVD mortality ( HR=1.057, 95% CI 1.010-1.107, P=0.018; HR=1.062, 95% CI 1.009-1.118, P=0.022). Conclusions:Increased arterial stiffness is relatively common in PD patients. Higher CF-PWV in PD patients is associated with increased age, diabetes and higher overhydration, and it is probably a valuable predictor of outcome in PD patients.

Objective: To investigate the epidemiological characteristics of human brucellosis in Jiaxing City from 2010 to 2021, so as to provide insights into the development of the brucellosis control strategy. Methods: The epidemiological and clinical data of brucellosis patients and epidemiological data of brucellosis outbreaks in Jiaxing City from 2010 to 2021 were collected from Chinese Disease Control and Prevention Information System, and the epidemiological features and outbreaks of brucellosis were analyzed descriptively. Results: Totally 160 brucellosis patients were reported in Jiaxing City from 2010 to 2021, and the incidence of brucellosis appeared a tendency towards a rise (χ2trend=28.564, P=0.002), with annual mean incidence of 0.29/105. No deaths due to brucellosis occurred in Jiaxing City from 2010 to 2021. Brucellosis cases were reported each month, which were concentrated in the first and second quarters, and the greatest number was seen in May (27 cases, 16.88%). The brucellosis cases were predominantly reported in Tongxiang City (114 cases, 71.25%), and 75.00% were male (120 cases) and 70.63% were occupational populations (113 cases). The patients had a median (interquartile range) age of 57 (12) years at onset, and the median duration (interquartile range) from onset to definitive diagnosis was 18 (28) days. The clinical manifestations mainly included fever and weakness, and a total of 18 Brucella melitensis isolates and one B. bovis isolate were cultured. Conclusions The incidence of brucellosis was rising in Jiaxing City from 2010 to 2021. The brucellosis patients were predominantly reported in Tongxiang City in the first and second quarters, and young, middle-aged men and occupational populations were at a high risk of brucellosis.

Objective To find out whether conversation analysis helps to differentiate psychogenic nonepileptic seizure (PNES) from epileptic seizure in Chinese patients.Methods Twelve unselected patients from Peking Union Medical College Hospital during 2014 to 2016 with diagnostic uncertainty were included.Interactions following standard protocol were carried out.A linguist blinded to all medical data and a neurologist studied videos and transcripts of the interactions.Using a diagnostic scoring aid which includes 17 conversation features summarized from previous researches, they attempted to predict the medical diagnosis of those patients independently.Results Accurate diagnosis was predicted in 10/12 patients by both raters.Average scores of patients with epileptic seizures were 8.00 (linguist) and 6.75 (neurologist), while average scores of paitents with PNES were-5.75 (linguist) and-7.88 (neurologist).Both raters agreed on most individual items (81.86%, 167/204).To demonstrate different features between these two groups, a case comparison was made between one patient with frontal lobe epilepsy and one patient with PNES.Conclusion In Chinese patients, conversation analysis can help differentiate between epileptic seizure and PNES.
