Objective:To investigate the effects of different doses of rosuvastatin on blood lipid levels and 1-year outcomes in patients undergoing coronary artery bypass grafting.Methods:A total of 106 patients who underwent coronary artery bypass grafting at the Affiliated Hospital of Jining Medical University from February 2020 to February 2022 were prospectively selected and randomly divided into two groups using a random number table. The high-dose group (53 cases) was treated with 20 mg/d rosuvastatin, while the low-dose group (53 cases) was treated with 10 mg/d rosuvastatin. The two groups were compared after treatment in terms of the clinical efficacy, blood lipid levels [total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C)], cardiac function indicators [left ventricular end diastolic diameter (LVDD), left atrial diameter (LAD), left ventricular ejection fraction (LVEF), one-year follow-up [recurrence, readmission, death, major adverse cardiovascular events (MACE)], and adverse reactions (liver injury, elevated creatine kinase, gastrointestinal reactions, rash).Results:The total effective rate of the high-dose group was 94.34%(50/53) higher than that of the low-dose group, which was 77.36%(41/53) ( P<0.05); After treatment, the levels of TC, TG, and LDL-C in both groups decreased, while the level of HDL-C increased (all P<0.05), and the levels of TC, TG, and LDL-C in the high-dose group were lower than those in the low-dose group, while the level of HDL-C was higher than that in the low-dose group (all P<0.05); After treatment, LVDD and LAD in both groups decreased, while LVEF increased (all P<0.05), and LVDD and LAD in the high-dose group were lower than those in the low-dose group, while LVEF was higher than that in the low-dose group (all P<0.05); After a one-year follow-up, the recurrence rate of the high-dose group was 7.55%(4/53), and the readmission rate was 5.66% (3/53), both lower than those of the low-dose group [26.42%(14/53), 20.75%(11/53)] (all P<0.05). There was no statistically significant difference in case fatality rate, MACE, and incidence of adverse reactions between the two groups (all P>0.05). Conclusions:The use of high-dose rosuvastatin in patients undergoing coronary artery bypass grafting can effectively reduce blood lipid levels, improve cardiac function, and has high safety. It is worthy of clinical application.

OBJECTIVE:
This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province.
METHODS:
We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed.
RESULTS:
The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α 3.7/αα (50.23%) and β IVS-II-654/β N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively.
CONCLUSION
Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

OBJECTIVE:
To explore the characteristics and clinical phenotypes of rheumatoid arthritis (RA) and provide the basis for further understanding, interventions and outcomes of this disease.
METHODS:
RA patients attended at Peking University People's Hospital from 2018 to 2021 were enrolled in the study. Data collection included demographic data, the sites and numbers of joints involved, extra-articular manifestations (EAM), comorbidities and laboratory variables. Statistical and bioinformatical analysis was performed to establish clinical subtypes by clustering analysis based on the type of joint involved, EAM involvement and other autoimmune diseases overlapped. The characteristics of each subtype were analyzed.
RESULTS:
A total of 411 patients with RA were enrolled. The mean age was (48.84±15.17) years, and 346 (84.2%) were females. The patients were classified into 4 subtypes: small joint subtype (74, 18.0%), total joint subtype (154, 37.5%), systemic subtype (100, 24.3%), and overlapping subtype (83, 20.2%). The small joint subtype had no medium or large joint involvement, and 35.1% had systemic involvement. The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels and platelet count (PLT) were lower than those in other subtypes, and the rates of positive rheumatoid factors (RF-IgA and RF-IgG) were significantly higher in the small joint subtype. The total joint subtype had both large and small joint involvement but no systemic involvement. The rate of morning stiffness and positive antinuclear antibodies (ANA) in this subtype were lower than those in other subtypes. In the systemic subtype, interstitial lung disease and secondary Sjögren syndrome were the most common systemic involvements, with prominent levels of disease activity score 28-joint count (DAS28-ESR and DAS28-CRP). The overlapping subtype was commonly combined with Hashimoto's thyroiditis or primary Sjögren syndrome. Female in the overlapping subtype was more common than in other subtypes. This subtype was characterized by hyperglobulinemia, hypocomplementemia and high rate of positive ANA, especially spotting type.
CONCLUSION
Based on the clinical features, RA patients could be classified into 4 subtypes: small joint subtype, total joint subtype, systemic subtype, and overlapping subtype. Each subtype had its own clinical characteristics. They help for further understanding and a more individualized treatment strategy of RA.

Objective: Traditional Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy can greatly decrease the anastomosis-related complications and reduce the incidence of reflux esophagitis, but its complexity limits the wide application. To decrease the complexity of Kamikawa anastomosis, the surgical team of Changzhi People's Hospital of Shanxi Changzhi Medical College improved this technique by using novel notion and reduced surgical procedures. This study aims to evaluate the efficacy and safety of modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy. Methods: A descriptive cohort study was carried out. Case enrollment criteria: (1) upper gastric carcinoma or esophagogastric junction carcinoma without distant metastasis was confirmed by preoperative gastroscopic biopsy and imaging examination; (2) tumor diameter was less than 4 cm; (3) preoperative clinical staging was cT1-3N1M0. Exclusion criteria: (1) patients received preoperative neoadjuvant chemotherapy; (2) patients had severe heart or lung disease, or poor nutritional status so that they could not tolerate surgery. Clinical data of 25 patients with upper gastric carcinoma or esophagogastric junction carcinoma who underwent modified Kamikawa anastomosis in digestive tract reconstruction in Heji Hospital (8 cases) and Changzhi People's Hospital (17 cases) from April 2019 to December 2020 were retrospectively collected. Of 25 patients, 21 were male and 4 were female, with mean age of 63.0 (49 to 78) years; 3 underwent open surgery and 22 underwent laparoscopic surgery. The modified Kamikawa anastomosis was as follows: (1) the novel notion of total mesangial resection of the esophagogastric junction was applied to facilitate the thorough removal of lymph nodes and facilitate hand-sewn anastomosis and embedding; (2) the diameter of the anastomotic stoma was selected according to the diameter of the esophageal stump, between 2.5 and 3.5 cm, to reduce the occurrence of anastomotic stenosis; (3) an ultrasonic scalpel was used to incise the esophageal stump, which could not only prevent bleeding of the esophageal stump, but also closely seal the esophageal mucosa, muscle layer and serosa to prevent esophageal mucosa retraction; (4) barbed suture was used to suture the remnant stomach fundus and esophagus to fix the stomach fundus in order to reduce the cumbersome and difficult intermittent sutures in a small space; (5) two barbed sutures were used to continuously suture the front and back walls of the anastomosis and complete the suture and fixation of the muscle flap. Relevant indicators of surgical safety, postoperative complications (using the Clavien-Dindo classification), esophageal reflux symptoms and the occurrence of esophagitis (using Los Angeles classification) were analyzed. The gastroesophageal reflux disease (GERD) score, gastroscopy, multi-position digestive tract radiography during postoperative follow-up were used to evaluate the residual gastric motility and anti-reflux efficacy. Results: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy was successfully performed in 25 patients. The surgical time was (5.8±1.8) hours, the intraoperative blood loss was (89.2±11.8) ml, and the average hospital stay was (13.8±2.9) days. Three cases (12.0%) developed postoperative anastomotic stenosis as Clavien-Dindo grade III and were healed after endoscopic dilation treatment. Postoperative upper gastrointestinal radiography showed 1 case (4.0%) with reflux symptoms as Clavien-Dindo grade I. Gastroscopy showed no signs of reflux esophagitis, and its Los Angeles classification was A grade. No anastomotic bleeding, local infection and death were found in all the patients. At postoperative 6-month of follow-up, GERD score showed no significant difference compared to pre-operation (2.7±0.6 vs. 2.4±1.0, t=-1.495, P=0.148). Conclusion: Modified Kamikawa anastomosis in digestive tract reconstruction after proximal gastrectomy is safe and feasible with good anti-reflux efficacy.

Targeting the poor powder characteristics of the contents in Hewei Jiangni Capsules, this study characterized the powder properties of the contents and employed particle design technique for improving the content quality. The content composite particles of Hewei Jiangni Capsules prepared by the particle design technique were evaluated by scanning electron microscopy(SEM), followed by infrared ray(IR), content uniformity, and in vitro dissolution detection. It was found that there was a good correlation between the crushed particle size of slices and the crushing time, and the calcined Haematitum was responsible for the poor content uniformity. After the fine powder of calcined Haematitum was super-finely ground for 8.5 min and those of the other contents in the capsule for 1 min, they were prepared into the composite particles, whose property characterizations were compared with those of the physical mixtures. The content uniformity of the prepared composite particles was significantly improved, and the preparation process was stable and reliable. The adoption of particle design technology to correct the poor uniformity of the physical mixture, solve the pharmaceutical defects of Hewei Jiangni Capsules, and improve the quality of prescriptions has provided important reference for the clinical application and development of Chinese medicinal preparations.

Based on the defects in powder properties of the contents of Ziyin Yiwei Capsules, this study screened out the main medicinal slice powders causing the poor powdery properties, and introduced the powder modification process to improve the powdery properties of these slice powders, the pharmaceutical properties of the capsule contents, and the content uniformity of Ziyin Yiwei Capsules, so as to provide a demonstration for the application of powder modification technology to the preparation of Chinese medicinal solid preparations. Through the investigation on the powder properties of the contents of Ziyin Yiwei Capsules, it was clarified that the pulverized particle size of the capsule contents had a good correlation with the pulverization time. According to the measurement results of the powder fluidity and wettability, the quality defects of the capsule contents were caused by the fine powders of Taraxaci Herba and Lungwortlike Herba. "Core-shell" composite particles were prepared from medicinal excipients magnesium stearate and fine powders of Taraxaci Herba and Lungwortlike Herba slices after ultra-fine pulverization to improve the powder properties of the problematic fine powders. Powder characterization data including fluidity and wettability were measured, followed by scanning electron microscopy(SEM) and infrared ray(IR) detection. It was determined that the optimal dosage of magnesium stearate was 2%, and the compositing time was 3 min. The composite particles were then used as content components of the Ziyin Yiwei Capsules. The powder characteristics between the original capsule and the modified composite capsule including the particle size, fluidity, wettability, uniformity of bulk density, and uniformity of chromatism as well as the content uniformity and in vitro dissolution were compared. The results showed that the powder characteristics and content uniformity of the prepared composite capsule were significantly improved, while the material basis of the preparation was not changed before and after modification. The preparation process was proved to be stable and feasible. The powder modification technology solved the pharmaceutical defects that were easy to appear in the preparation of traditional capsules, which has provided experimental evidence for the use of powder modification technology for improving the quality of Chinese medicinal solid preparations and promoting the secondary development and upgrading of traditional Chinese medicinal dosage forms such as capsules.

Objective: The moisture content in the soil directly affects the yield and quality of Panax notoginseng, especially at the age of three years old. However, the suitable moisture for the growth of P. notoginseng is unknown. In this study, the effects of different soil moisture on the growth of P. notoginseng were studied. Methods: Four different water treatments (0.45 field capacity (FC), 0.60 FC, 0.70 FC, and 0.85 FC) were set up in Shilin County, Yunnan Province, China. The water consumption and daily dynamic of water consumption were determined daily (from April 21 to October 18, 2012), and the daily dynamic of water consumption under different weather conditions (sunny and rainy) was determined. The transpiration coefficient and water use efficiency were calculated through dry matter accumulation and total water consumption. Accumulation of saponins of roots of P. notoginseng were analyzed by HPLC after treated, and the soil moisture content suitable for the growth of P. notoginseng was estimated by regression fitting of the active ingredient accumulation and the soil moisture content. Results: The water consumption of 0.85 FC, 0.70 FC, 0.60 FC and 0.45 FC were 2.89, 3.68, 3.37 and 2.73 kg/plant per day, respectively. The water consumption of P. notoginseng from June to August was greater than other months. The daily dynamic of water consumption on sunny days and sunny days after rain showed a “double peak” feature, and it showed a “single peak” feature on rainy days. The water uses efficiency (WUE) of 0.85 FC, 0.70 FC, 0.60 FC and 0.45 FC were 2.51, 3.32, 4.59, 3.39 gDW/kg H

OBJECTIVE:
To observe the postoperative bleeding after percutaneous renal biopsy (PRB) in Tibet, To analyze and summarize the risk factors associated with bleeding in high altitude patients to improve the safety of surgery.
METHODS:
A retrospective analysis of 150 cases of PRB in the Department of Nephrology, People's Hospital of Tibet Autonomous Region from May 2016 to May 2018 were carried out, and the correlations between the potential risk factors (gender, age, blood pressure, hemoglobin, platelet, serum creatinine) and postoperative bleeding events were analyzed.
RESULTS:
During the study period, the 150 patients receiving procedure of PRB were enrolled in our hospital, with an average age of (41.2±15.6) years, of whom 58.7% (88/150) were male, 41.3% (62/150) were female, and major bleeding complications occurred in 12 biopsies (8.0%, 12/150). Six cases for men and women, respectively. The mean age in the bleeding group seemed to be higher than that in the non-bleeding group [(48.3±20.0) years vs. (40.6±15.1) years, P=0.099]. There was no significant difference in the incidence of hypertension, hemoglobinemia, urea nitrogen and prothrombin time between the two groups. The level of serum creatinine in the hemorrhage group seemed to be higher than that in the non-bleeding group (P=0.090), and the time of the hemorrhagic group was longer than that in the non-bleeding group (P=0.069). The platelet count in the bleeding group was significantly lower than that in the non-bleeding group (P < 0.05). Multivariate Logistic regression analysis showed that the prolonged activation of partial prothrombin time and lower platelet count had a relatively high risk of bleeding, which was statistically significant (P=0.079, P=0.082).
CONCLUSION
PRB is safe and reliable on the whole in plateau areas; Old age, low platelet count, decreased renal function and prolonged activated partial coagulation time are related to postoperative bleeding of PRB, and hyperhemoglobin is not a risk factor for bleeding. High hemoglobin is not a risk factor for postoperative bleeding of PRB at high altitude.
