To improve the oil yield of Chuanxiong volatile oils and keep their quality same as that of oils prepared by steam distillation (SD) for short), a new technology of coupling water extraction and rectification (WER for short) was applied to isolate Chuanxiong volatile oils. The oil yield, as well as GC-MS chromatogram of the volatile oils extracted by WER and SD were compared. The oil yield of WER (0.50%) was that of SD (0.20%). There were 21 common constituents in the two kinds of volatile oils, which occupied 98.94% of the oils extracted by SD, 98.80% of that by WER, respectively. Moreover, the relative percentage of the common constituents was almost the same. The results indicate that WER could not only increase the oil yield of Ligusticum chuanxiong, but also keep the quality of the oils accord with that extracted by SD.

In a word, this teaching reform has achieved good results in practice.

Objective:To analyze the dynamic development of physical, psychological, and cognitive degenerative multimorbidity among middle-aged and older Chinese adults (≥45 years old) while estimating the longitudinal association between socioeconomic status (SES) and the progression of multimorbidity.Methods:Based on data from the China Health and Retirement Longitudinal Study (2011-2020), the Sankey diagram was used to show the dynamic development of physical, psychological, and cognitive degenerative multimorbidity from 2011 to 2020. SES was constructed based on the level of education and total household wealth. Logistic regression was used to estimate OR and 95% CI to evaluate the association between SES and the progression of multimorbidity. Results:Of the 5 393 participants included, 4 484 (83.14%) of them developed new diseases, and the prevalence of physical, psychological, and cognitive degenerative multimorbidity increased from 38.04% to 74.23%. Compared to those with no reported disorders at baseline, participants with psychological disorder (for newly developed physical-cognitive multimorbidity: OR=4.59,95% CI: 2.89-7.29), cognitive disorder (for newly developed physical-psychological multimorbidity: OR=2.24,95% CI: 1.40-3.60), or their multimorbidity at baseline were more likely to progress to physical, psychological, and cognitive degenerative multimorbidity. After adjusting covariates, individuals with low SES were more likely to develop physical diseases ( OR=1.45, 95% CI: 1.11-1.89), cognitive disorder ( OR=1.84, 95% CI: 1.16-2.91), physical-psychological multimorbidity ( OR=1.87, 95% CI: 1.37-2.56), physical-cognitive multimorbidity ( OR=3.58, 95% CI: 2.54-5.06), psychological-cognitive multimorbidity ( OR=5.66, 95% CI: 3.04-10.55), and physical-psychological-cognitive multimorbidity ( OR=3.21, 95% CI: 2.06-5.01) in comparison to those with high SES. There is a dose-response relationship between SES and the multimorbidity progression (all trend P<0.001). Conclusions:The prevalence of physical, psychological, and cognitive degenerative multimorbidity increased significantly among middle-aged and older Chinese adults. Lower SES was associated with multiple patterns of physical, psychological, and cognitive disorders progression.

Objective To study the effect of perioperative nursing intervention for laparoscopic ovarian cystectomy.Methods A total of 120 patients who underwent laparoscopic ovarian cyst resection in our hospital were selected as research subjects.All the patients were divided into control group and observation group according to random number table method,with 60 cases in each group.The patients in the control group were received routine care,and the patients in the observation group were given perioperative nursing intervention based on the control group.The postoperative anal exhaust time,bedridden time,length of hospital stay,postoperative pain and complication rate were statistically analyzed and compared between the two groups.Results The time of anal exhaust,bedridden time and hospital stay were lower in the observation group than that in the control group (P ＜0.05);There was no significant difference in VAS score after operation between the two groups (P ＞0.05).The VAS score of the observation group was significantly lower than that of the control group at 24,48 and 72 hours after operation (P ＜ 0.05).The overall incidence of postoperative complications in the observation group was lower than that in the control group (8.3％ vs.23.3％,P ＜0.05).Conclusion Laparoscopic ovarian cyst resection in patients with perioperative nursing intervention can effectively shorten the recovery time of patients,reduce the risk of complications and promote patient rehabilitation,so it is worthy of application and promotion.

Objective To determine vascular endothelial growth factor(VEGF)-460 gene polymorphism in Uyghurs and its relationship to urolithiasis in south Xinjiang. Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP),gene sequencing and genetic analysis methods were used in 200 urolithiasis patients of Uyghurs, and 200 healthy Uyghurs. Results The distribution of genotype and allele had no significant difference between urolithiasis patients and normal controls (P＞0. 05). The frequencies for the CC,TT and CT genotypes in patients with urolithiasis and normal controls were 1.5 %, 29.0 %, 69.5 % and 0. 5 %, 27.5 %, 72.0 %, respectively. The frequencies for C and T allele were 36.2%,63.7% and 36.9% ,63.1%, respectively. Conclusions The results of VEGF-460 gene polymorphisms indicate no significant relationship between patients with turolithiasis and normal controls in Uyghurs in south Xinjiang,which may not be urolithiasis susceptibility genetic locus.

OBJECTIVE: To determine the frequency of chromosomal abnormalities and outcome of pregnancy for fetuses with increased nuchal translucency (NT). METHODS: Between July 2014 and February 2018, 247 fetuses with increased NT (>95th centile)were analyzed by chromosome microarray analysis (CMA). The fetuses were divided into ones with isolated increased NT (168 cases), increased NT with cystic hygroma (20 cases), increased NT with edema (12 cases) or increased NT with other abnormalities (47 cases). All couples were followed up by telephone calls. RESULTS: The rate of chromosomal abnormalities was 31.6% (78/247), which included 66 cases with chromosomal aneuploidies and 12 with copy number variants (CNVs). CNVs accounted for 31.4% (11/35) of total abnormalities among fetuses with isolated increased NT, whilst only 2.3% (1/43) of the total abnormalities among fetuses with non-isolated increased NT. Three fetuses with a normal CMA result had mental and physical retardation. Two of them were diagnosed with single gene disorders by whole exome sequencing. CONCLUSION CMA can detect more chromosomal microdeletion/microduplications among fetuses with isolated increased NT. Furthermore, fetuses with increased NT and anegative CMA result during pregnancy cannot exclude all adverse outcomes.

Objective:To observe any effects of electroacupuncture (EA) on urodynamics and bladder c-Kit expression in rats with urination disorders after spinal cord injury (SCI).Methods:Complete spinal cord injury models were created in female Sprague-Dawley rats by transecting the spine at the thoracic or sacral level. On day 22 after the injury, the rats with successful modeling were randomized into a thoracic spinal cord injury (TSCI) group, a TSCI+ EA group, a sacral spinal cord injury (SSCI) group and an SSCI+ EA group, each of 10. Both EA groups were given 15 minutes of EA at the Guanyuan (CV4) and Sanyinjiao (SP6) points daily for 14 days. After the intervention, urination function was evaluated using bladder volume, compliance and residual urine volume. Hematoxylin and eosin staining was used to observe any morphological changes in bladder tissues. The gene and protein expression of c-Kit in bladder tissues were detected using real-time quantitative polymerase chain reactions and western blotting.Results:Compared with the sham group, the bladder volume and compliance of the TSCI group decreased significantly, while the average residual urine volume increased significantly. In the SSCI group the average residual urine volume, bladder volume and compliance all increased significantly. The modeling altered the morphology of the bladder in all of the SCI rats. The average expression of c-Kit mRNA and protein increased significantly in TSCI group, but both decreased significantly in the SSCI group. EA improved the histological structure of the SCI rats′ bladders.Conclusions:EA can bi-directionally regulate bladder c-Kit expression, and that is a possible mechanism for improving urinary incontinence and urine retention after an SCI.

Objective:To analyze the changes of NOD-like receptor family pyrin domain-containing protein 3 (NLRP3) inflammasomes in peripheral blood of patients with diabetic nephropathy (DN) and its clinical significance.Methods:208 patients with type 2 diabetes (T2DM) admitted to our hospital from Feb. 2018 to Dec. 2020 were selected and were divided them into 3 groups according to the urine albumin (UA) /urinary creatinine (UC) ratio (UACR) : simple T2DM group (UACR<30 mg/g) 83 cases, microalbuminuria group (UACR 30-300 mg/g) 70 cases, and massive proteinuria group (UACR>300 mg/g) 55 cases; Fifty healthy volunteers were selected as the control group. General data of each group were collected. Western blot was used to detect the level of NLRP3 in peripheral blood, and enzyme-linked immunosorbent assay (ELISA) kit was used to detect the level of serum interleukin (IL) -1β and IL-18. Logistic regression was employed to analyze the occurrence of DN in T2DM patients. Receiver operating characteristic curve (ROC) curve was used to analyze the value of NLRP3, IL-1β, IL-18 in the diagnosis of DN in peripheral blood.Results:Compared with the control group, the course of disease, FBG, LDL-C, TG, TC, SCr, BUN, HbA1c, NLRP3 protein, IL-1β and IL-18 significant increased in the other 3 groups, and HDL-C, ALB, and eGFR were significant decreased, and the difference was statistically significant ( P<0.05) . The order of their level changes was: massive proteinuria group>microalbuminuria group>pure T2DM group; Pearson test found that peripheral blood NLRP3, IL-1β, IL-18 levels were significantly positively correlated with UACR, LDL-C, TG, and TC ( P<0.001) , while they were significantly negatively correlated with HDL-C ( P<0.001) .The results of unconditional Logistic regression analysis showed that the course of disease, FBG, HDL-C, LDL-C, TG, TC, SCr, BUN, ALB, HbA1c, eGFR, NLRP3 protein, IL-1β and IL-18 may all be related to DN-related in patients with T2DM ( P<0.05) . Multivariate analysis found that high levels of BUN, ALB, HbA1c, EGFR, NLRP3 protein and IL-1 were found β and IL-18 are high risk factors for DN in patients with T2DM ( P<0.05) . The ROC curve showed that the combination of peripheral blood NLRP3, IL-1β, and IL-18 predicted the highest AUC, sensitivity, and specificity of DN in patients with T2DM as 0.918, 93.40%, and 90.13%, respectively. Conclusions:Different stages of DN are often accompanied by increased levels of NLRP3, IL-1β, and IL-18 in peripheral blood. Strengthening the monitoring of NLRP3 inflammasome levels can help assess the renal function of patients and provides a theoretical basis for early diagnosis of DN.
