Abstract Ischemic stroke is characterized by high morbidity, disability and mortality. At present, there is a lack of effective treatment for ischemic stroke, so it is of great significance to reduce the incidence risk of ischemic stroke. Studies show that vitamin C can prevent atherosclerosis, thus reduce the incidence risk of ischemic stroke. However, this point is controversial due to the differences of study population, inconsistent evaluation methods of vitamin C content and the influence of various confounding factors. This paper reviews the related animal experiments, clinical trials and cohort studies, in order to provide reference for subsequent studies on reducing the incidence risk of ischemic stroke.

Background:Oryz-Aspergillus Enzyme and Pancreatin Tablet is a double-deck digestive enzyme pellet containing Oryz-Aspergillus enzyme and pancreatin that has been widely used for treatment of functional dyspepsia (FD)in clinical practice. However,there is no randomized controlled trial focusing on the efficacy of this agent versus other drugs used for treatment of FD such as prokinetics and proton pump inhibitors (PPI). Aims:To compare the efficacy and safety among Oryz-Aspergillus Enzyme and Pancreatin Tablet,Domperidone Tablet and Esomeprazole Magnesium Enteric-coated Tablet, three drugs with different mechanisms of action on FD,in Chinese population. Methods:A total of 82 Helicobacter pylori-negative outpatients fulfilling the diagnostic criteria of FD in Rome Ⅲ were recruited from Nov. 2015 to Jun. 2016 at the First Affiliated Hospital of Zhejiang Chinese Medical University. These patients were randomly allocated into 3 groups,and received Oryz-Aspergillus Enzyme and Pancreatin Tablet (group A),Domperidone Tablet (group B)and Esomeprazole Magnesium Enteric-coated Tablet (group C)orally for 4 weeks,respectively. The improvement of dyspeptic symptoms and adverse events were observed and recorded. Results:After 4 weeks treatment,the overall efficacies for global symptoms in group A,group B and group C were 93. 1%,88. 9% and 69. 2%,respectively,statistically significant difference was existed among the three groups (P < 0. 05). Domperidone Tablet was effective for postprandial fullness and early satiety;Esomeprazole Magnesium Enteric-coated Tablet was sensitive for epigastric pain,epigastric burning,and belching and regurgitation;the efficacies of Oryz-Aspergillus Enzyme and Pancreatin Tablet for all five dyspeptic symptoms were in between. No adverse events were observed during treatment course. Conclusions:Digestive enzymes,prokinetics and PPI have different sensitive symptoms and optimal indications for treatment of FD. The overall efficacy of Oryz-Aspergillus Enzyme and Pancreatin Tablet is superior to that of prokinetics and PPI.

OBJECTIVE To evaluate the effects of pharmaceutical interventio n led by clinical pharmacists on medication appropriateness of elderly inpatients. METHODS A non-randomized concurrent controlled trial was carried out. Elderly patients admitted to two treatment groups in the geriatric department of Yancheng First People ’s Hospital since June 2021 were selected as the research objects. According to the inclusion and exclusion criteria ，the first 40 patients were selected from each of the two treatment groups （according to the order of admission time ）and set as the control group or the intervention group. The control group received routine treatment and nursing services ，and the intervention group additionally received pharmaceutical intervention led by clinical pharmacists on the basis control group. Clinical pharmacists found potential inappropriate medication （PIM）and put forward suggestions on optimization of medication regimen. American Geriatrics Society 2019 Updated AGS Beers Criteria ® for PIM Use in Older Adults （hereinafter referred to as “Beers criteria ”）and the Criteria of PIMs for Older Adults in China 2017 Edition （hereinafter referred to as “Chinese criteria ”）were used as reference tools for drug use review. The medication appropriateness index （MAI）total scores （main evaluation indicator ），the number of PIMs ，the number of drugs used ，the length of hospital stay ，the number of drug-related adverse events during hospital stay ，the number of drug regimen optimization suggestions by pharmacists ， and implementation rate of E-mail：zhihuadou@163.com optimization suggestions adopted by clinicians were compared between 2 groups at admission and at discharge. RESULTS At admission ，there were no statistically differences in MAI total scores，the number of PIMs based on Beers criteria ，the number of PIMs based on Chinese criteria or the number of drugs used between 2 groups（P＞0.05）. At discharge ，there were no statistically differences in the number of PIMs based on Chinese criteria and the length of hospital stay between 2 groups（P＞0.05），but the MAI total scores ，the number of PIMs based on Beers criteria and the number of drugs used in the intervention group were lower than those in the control group （P＜0.05）. In the intervention group，the proportion of drugs recorded as “inappropriate medication ”at admission （34.5％）was significantly higher than that at discharge（19.5％）（P＜0.05）. The difference between the number of drugs discharged from hospital and the number of drugs admitted to hospital in the control group [ 3（1-4.8)] was significantly higher than that in the intervention group [ 1（0-2.8)]（P＝ 0.012）. Compared with admission ，the proportion of drugs recorded as “inappropriate medication ”in the intervention group at discharge was significantly decreased on the basis of “effectiveness”dimension and “course”dimension （P＜0.05）. During hospitalization，clinical pharmacists put forward 70 optimization suggestions of drug regimen for the intervention group ，among which 39 suggestions were adopted and implemented by clinicians ，with an implementation rate of 55.7％. CONCLUSIONS The pharmaceutical intervention led by clinical pharmacists can improve overall appropriateness of drug use in the elderly inpatients using MAI as main evaluation indicator.

Objective:To investigate the clinical characteristics of choledocholithiasis com-bined with periampullary diverticulum and influencing factor for difficult cannulation of endoscopic retrograde cholangiopancreatography (ERCP).Methods:The retrospective case-control study was conducted. The clinical data of 1 920 patients who underwent ERCP for choledocholithiasis in 15 medical centers, including the First Hospital of Lanzhou University, et al, from July 2015 to December 2017 were collected. There were 915 males and 1 005 females, aged (63±16)years. Of 1 920 patients, there were 228 cases with periampullary diverticulum and 1 692 cases without periampullary diverticulum. Observation indicators: (1) clinical characteristics of patients with choledocholithiasis; (2) intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis; (3) influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and com-parison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Clinical characteristics of patients with choledocholithiasis. Age, body mass index, cases with complications as chronic obstructive pulmonary disease, diameter of common bile duct, cases with diameter of common bile duct as <8 mm, 8?12 mm, >12 mm, diameter of stone, cases with number of stones as single and multiple were (69±12)years, (23.3±3.0)kg/m 2, 16, (14±4)mm, 11, 95, 122, (12±4)mm, 89, 139 in patients with choledocholithiasis combined with periampullary diverticulum, versus (62±16)years, (23.8±2.8)kg/m 2, 67, (12±4)mm, 159, 892, 641, (10±4)mm, 817, 875 in patients with choledocholithiasis not combined with periampullary diver-ticulum, showing significant differences in the above indicators between the two groups ( t=?7.55, 2.45, χ2=4.54, t=?4.92, Z=4.66, t=?7.31, χ2=6.90, P<0.05). (2) Intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis. The balloon expansion diameter, cases with intraoperative bleeding, cases with hemorrhage management of submucosal injection, hemostatic clip, spray hemostasis, electrocoagulation hemostasis and other treatment, cases with endoscopic plastic stent placement, cases with endoscopic nasal bile duct drainage, cases with mechanical lithotripsy, cases with stone complete clearing, cases with difficult cannulation, cases with delayed intubation, cases undergoing >5 times of cannulation attempts, cannulation time, X-ray exposure time, operation time were 10.0(range, 8.5?12.0)mm, 56, 6, 5, 43, 1, 1, 52, 177, 67, 201, 74, 38, 74, (7.4±3.1)minutes, (6±3)minutes, (46±19)minutes in patients with choledocholithiasis combined with periampullary diverticulum, versus 9.0(range, 8.0?11.0)mm, 243, 35, 14, 109, 73, 12, 230, 1 457, 167, 1 565, 395, 171, 395, (6.6±2.9)minutes, (6±5)minutes, (41±17)minutes in patients with choledocholithiasis not combined with periampullary diverticulum, showing significant differences in the above indicators between the two groups ( Z=6.31, χ2=15.90, 26.02, 13.61, 11.40, 71.51, 5.12, 9.04, 8.92, 9.04, t=?3.89, 2.67, ?3.61, P<0.05). (3) Influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Results of multivariate analysis showed total bilirubin >30 umol/L, number of stones >1, combined with periampullary diverticulum were indepen-dent risk factors for difficult cannulation in patients with periampullary diverticulum who underwent ERCP for choledocholithiasis ( odds ratio=1.31, 1.48, 1.44, 95% confidence interval as 1.06?1.61, 1.20?1.84, 1.06?1.95, P<0.05). Results of further analysis showed that, of 1 920 patients undergoing ERCP for choledocholithiasis, the incidence of postoperative pancreatitis was 17.271%(81/469) and 8.132%(118/1 451) in the 469 cases with difficult cannulation and 1 451 cases without difficult cannula-tion, respectively, showing a significant difference between them ( χ2=31.86, P<0.05). In the 1 692 patients with choledocholithiasis not combined with periampullary diverticulum, the incidence of postopera-tive pancreatitis was 17.722%(70/395) and 8.250%(107/1 297) in 395 cases with difficult cannula-tion and 1 297 cases without difficult cannulation, respectively, showing a significant difference between them ( χ2=29.00, P<0.05). In the 228 patients with choledocholithiasis combined with peri-ampullary diverticulum, the incidence of postoperative pancreatitis was 14.865%(11/74) and 7.143%(11/154) in 74 cases with difficult cannulation and 154 cases without difficult cannulation, respectively, showing no significant difference between them ( χ2=3.42, P>0.05). Conclusions:Compared with patients with choledocholithiasis not combined with periampullary divertioulum, periampullary divertioulum often occurs in choledocholithiasis patients of elderly and low body mass index. The proportion of chronic obstructive pulmonary disease is high in choledocholithiasis patients with periampullary diverticulum, and the diameter of stone is large, the number of stone is more in these patients. Combined with periampullary diverticulum will increase the difficult of cannulation and the ratio of patient with mechanical lithotripsy, and reduce the ratio of patient with stone complete clearing without increasing postoperative complications of choledocholithiasis patients undergoing ERCP. Total bilirubin >30 μmol/L, number of stones >1, combined with periampullary diverticulum are independent risk factors for difficult cannulation in patients of periampullary diverticulum who underwent ERCP for choledocholithiasis.

ObjectiveIn order to find a fast odor-based method for the identification of sulfur fumigated Gastrodiae Rhizoma， an ultra-fast gas phase electronic nose technology was used to identify the odors of different degrees of sulfur fumigated Gastrodiae Rhizoma decoction pieces. MethodHeracles NEO ultra-fast gas phase electronic nose was employed to collect gas chromatograms of unsulfured and sulfured with different degrees of Gastrodiae Rhizoma decoction pieces， gas chromatograms were performed under programmed temperature （initial temperature of 40 ℃， 0.2 ℃·s^-1 to 60 ℃， and then 4 ℃·s^-1 to 250 ℃）， the sample volume was 5 mL， the incubation temperature was 65 ℃ and incubation time was 35 min. Kovats retention index and the AroChemBase database were used for qualitative analysis， and stoichiometric analysis was performed on this basis. Principal component analysis （PCA）， discriminant factor analysis （DFA） and partial least squares-discriminant analysis （PLS-DA） models were established to identify the Gastrodiae Rhizoma decoction pieces with different degrees of sulfur fumigation. ResultAccording to the comparative analysis of AroChemBase database， there were significant differences in the odor characteristics of sulfur fumigated and non-sulfur fumigated Gastrodiae Rhizoma， cyclopentane， acetone and heptane might be the odor components to distinguish the degree of sulfur fumigation in Gastrodiae Rhizoma decoction pieces. The identification index of PCA model was 81， the accumulative discriminant index of the discriminating factors was 92.09% in DFA model， the supervisory model interpretation rate of PLS-DA model was 0.963 and the predictive ability parameter was 0.956， indicating that PCA， DFA and PLS-DA models could well distinguish Gastrodiae Rhizoma decoction pieces with different sulfur fumigation degrees. ConclusionHeracles NEO ultra-fast gas phase electronic nose can be used as a rapid method to identify and distinguish Gastrodiae Rhizoma decoction pieces with different levels of sulfur fumigation. Meanwhile， it can provide a rapid， simple and green method and technology for identification of traditional Chinese medicine decoction pieces by sulfur fumigation.

Pure-tone audiometry can be performed to evaluate the type and degree of hearing loss， whose results can be divided into four types including low-frequency descending， high-frequency descending， flat descending and total deafness. The low-frequency descending type of sudden hearing loss （SHL） is more likely to be spleen deficiency and dampness exuberance， the high-frequency descending type is often due to yin deficiency of liver and kidney， the flat descending type is commonly associated with qi and blood depletion， and the type of total deafness is often linked to blood stasis. Our team has further developed a comprehensive diagnostic and therapeutic approach for SHL， emphasizing "the integration of disease and syndrome， the combination of acupuncture and herbal medicine， and dynamically administering treatment". Firstly， it advocates integrating disease diagnosis with syndrome differentiation. Secondly， it recommends combining acupuncture and herbal medicine， with local acupoints such as Ermen （TE 21）， Tinggong （SI 19）， Tinghui （GB 2）， and Yifeng （TE 17） used to unblock the auditory orifice， and herbal prescriptions tailored to the hearing curve patterns. For the low-frequency descending type， it is recommended to fortify the spleen and percolate dampness by taking distal points of spleen channel and stomach channel and using Shenling Baizhu Powder （参苓白术散）. For the high-frequency descending type， the method of nourishing kidney and calming liver is recommended， using distal points of kidney and liver channels and taking Erlong Zuoci Pills （耳聋左慈丸）. Regarding the flat descending type， tonifying qi and nourishing blood is advised， for which acupoints of Conception Vessel， spleen， stomach and large intestine channels can be needled， and Yiqi Congming Decoction （益气聪明汤） can be administered. For the total deafness type， it is recommended to activate blood and dissipate stasis， often with Xuehai （SP 10） and Geshu （BL 17） needled and Tongqiao Huoxue Decoction （通窍活血汤） administered. All these are conducted to treat the root and branch simultaneously. At the same time， it emphasizes the need to consider complex syndrome presentations and disease progression， dynamically analyze the disease causes and mechanisms， and adjust treatment according to the changing syndromes. In conclusion， this article is expected to inspire clinical diagnosis and treatment of SHL.
