OBJECTIVE To investigate the changes in high performance liquid chromatography (HPLC) fingerprint spectra and nucleoside components between Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and its processed product Succus bambusae pinella preparata, providing a reference for the quality evaluation of the latter. METHODS HPLC fingerprint was established for 10 batches of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and its processed product Succus bambusae pinella preparata following the Similarity Evaluation System of TCM Chromatographic Fingerprints (2012 Edition). Hierarchical cluster analysis (HCA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS- DA) were conducted on their common peaks. The contents of four nucleoside components, hypoxanthine, uridine, adenine, and guanosine, in both Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata were determined. RESULTS The similarity between the fingerprints of the 10 batches of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, Succus bambusae pinella preparata, and their corresponding reference fingerprints ranged from 0.851 to 0.990. A total of 10 common peaks were obtained for both samples, and 4 components were identified as hypoxanthine, uridine, adenine, and guanosine. The results of HCA, PCA and OPLS-DA showed that the samples of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata were clustered into separate categories, with OPLS-DA selecting 4 differential components between them, ranked by variable importance projection values as peak 8, peak 1, peak 6 (adenine) and peak 10. The content determination results showed that the average contents of hypoxanthine, uridine, adenine and guanosine in Succus bambusae pinella preparata declined by 15.90%, 12.00%, 26.04% and 22.18% compared to Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, respectively, with statistically significant differences in the contents of hypoxanthine, adenine and guanosine (P<0.05 or P<0.01). CONCLUSIONS The established fingerprint and content determination methods are simple to operate and have good repeatability, which are suitable for qualitative and quantitative analysis of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Succus bambusae pinella preparata. The average contents of the four nucleoside components decreased after the processing of Succus bambusae pinella preparata.

Objective:To evaluate the effect of self-made lithotomy heating mask on intraoperative and postoperative body temperature and short-term postoperative outcome indicators in patients undergoing radical resection of rectal cancer.Methods:Using the method of quasi experimental research design, 100 patients with open rectal cancer in Ningbo Huamei Hospital of the University of Chinese Academy of Sciences from February to July 2021 were selected as the research objects. The patients were divided into experimental group and control group with 50 cases in each group. The control group was kept warm by routine methods, and the experimental group was kept warm by self-made lithotomy heating hood. The changes of core temperature at different time points before, during and after operation were compared between the two groups. The incidence of accidental hypothermia and shivering, the recovery time of anesthesia, and the incidence of various complications within 48 hours after operation were compared between the two groups after operation from the beginning of the operation to 6 hours after returning to the ward.Results:From 30 minutes after anesthesia to 3 hours after entering the ward, the core temperatures of the experimental group at 10 time points were higher than that of the control group, and the differences were statistically significant ( t values were 3.48-37.30, all P<0.01). From the beginning of surgery to 6 h after returning to the ward, the incidence of perioperative accidental hypothermia in the experimental group was 2% (1/50), lower than 24% (12/50) in the control group, and the difference was statistically significant ( χ2=11.06, P<0.05) . The number of cases of shivering in the experimental group was 10, lower than that in the control group of 22, the difference was statistically significant ( χ2=6.62, P<0.05) . The recovery time, extubation time and stay time in anesthesia recovery room of the experimental group were (8.44 ± 2.83), (13.05 ± 4.72), (74.51 ± 11.82) min, which were shorter than those of the control group (15.35 ± 2.09), (17.62 ± 3.28), (89.14 ± 9.19) min, and the difference was statistically significant ( t=-13.89, -5.62, -6.91, all P<0.01). The number of cases of agitation, delirium and nausea and vomiting in the experimental group was 3, 1 and 2 respectively, which was lower than 13, 7 and 8 in the control group, and the difference were statistically significant ( χ2=7.44, 4.89, 4.00, all P<0.05). There was no significant difference in the incidence of adverse cardiac events between the two groups ( P>0.05). Conclusions:The application of self-made lithotomy heating mask in open rectal cancer surgery can effectively improve the risk of hypothermia at different time points during and after surgery, reduce the incidence of shivering, restlessness, postoperative nausea, vomiting and delirium, shorten the time of awakening and extubation, and prevent postoperative complications.

Heart failure, as a progressive and irreversible clinical syndrome, is an important part of the global prevention and treatment of chronic cardiovascular diseases. The management of its complex symptoms and risk factors cannot completely rely on medical and nursing staff and short-term clinical treatment. Self-care is an effective way to reduce the readmission rate and fatality rate of patients. Symptom perception is a new dimension in the situation-specific theory of self-care in heart failure, and that is a comprehensive process by which patients conduct self-monitoring of symptoms and signs and identify, interpret, and label the meaning of symptoms. Symptom perception of heart failure is crucial to achieve effective self-care, however, there are few studies in China. This article reviews the definition, influencing factors and evaluation tools of symptom perception in patients with heart failure, so as to provide evidence for the intervention and promotion of symptom perception in patients with heart failure.

Objective:To investigate the molecular characteristics, drug resistance rate and virulence genes harboring status of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) associated with skin and soft tissue infections (SSTIs), and provide epidemiological basis for clinical antibiotic usage and infection prevention and control. Methods:The Staphylococcus aureus associated with SSTIs in Quzhou People′s Hospital from 2014 to 2018 were retrospectively analyzed. A total of 72 CA-MRSA isolates were screened, and molecular typing was performed by multilocus sequence typing (MLST). K-B method and micro broth dilution method were used to analyze the antibiotic susceptibilities of those strains. The virulence genes screened including fibronectin binding protein genes (fnbA, fnbB),hemolysin genes (hla, hlb), enterotoxin genes (sec, seh) and leukocidin gene (PVL) were detected by polymerase chain reaction (PCR).Statistical analysis of differences between drug resistance rates and virulence genes carrier rates between ST59 and non-ST59 groups used were Chi-square test or Fisher exact test. Results:ST59 type was the main epidemic clone in skin and soft tissue infection CA-MRSA in Quzhou area with account for 55.56% (40/72). All isolates had higher resistance rates to erythromycin (90.28%, 65/72), clindamycin (68.06%, 49/72) and tetracycline (41.67%, 30/72). The nitrofurantoin, daptomycin and linezolid were all sensitive. The resistance rate to clindamycin of sequence type 59 (ST59) was (85.00%, 34/40). The resistance rate of ST59 to clindamycin was significantly higher than that of other clone types (χ 2=11.886, P<0.01). There was no significant difference in the resistance rates of other antibiotics. All 72 isolates exhibited carriage of virulence genes as follows, hla (97.22%, 70/72) , hlb (33.33%, 24/72) , fnbA (50.00%, 36/72) , fnbB (48.61%, 35/72) , PVL (63.89%, 46/72) , sec (4.17%, 3/72) , seh (4.17%, 3/72) . The carrier rate of PVL gene in ST59 type was (77.50%, 31/40). ST59 showed higher rates of PVL genes compared with other clone types (χ 2=7.227, P<0.01). Conclusions:The main clone of CA-MRSA associated with SSTIs in Quzhou was ST59, which was similar to other parts of the Country. The carrying rate of PVL gene of ST59 isolate was significantly higher than that of other isolates. CA-MRSA associated with SSTIs has a high resistance rate to erythromycin and clindamycin, which should not be used as the first choice in treatment.

Objective To evaluate the feasibility of quantitative evaluation of fallopian tubes patency by the rising slope of pressure curve produced by bolus injection using a liquid diagnostic apparatus in the four-dimen-sional hysterosalpingo-contrast sonography. Methods A total of 205 patients with infertility were collected for four-dimensional hysterosalpingo-contrast sonography. In the examination,the contrast medium concentration,the liquid volume of the liquid diagnostic apparatus and the speed of the liquid were stationary calculated. The rising slope of the curve was calculated according to the real-time pressure curve produced by the contrast agent injection process. According to the hysterosalpingo-contrast sonography examination's results ,patients were divided into one side patency group,one side partial obstruction group and one side obstruction group. The correlation between the slope and the patency of the fallopian tube was analyzed by binary logistic regression. Results Binary logistic regression showed that the slope and fallopian tube patency had good correlation(all P < 0.05)between one side patency group and one side obstruction group,and also between one side partial obstruction group and one side obstruction group;but had no correlation between one side patency group and one side partial obstruction group(regression coefficient P>0.05,regression constant P=0.000). Conclusion The slope of pressure curve produced by four-dimensional hysterosalpingo-contrast sonography can be used to assess the patency of fallopian tubes quantitatively. It is a new auxiliary index for evaluating the patency of fallopian tubes.
