Lian Qiao Bai Du Wan was used to study the identification of Chinese patent medicine by molecular marker technique. DNA was extracted through modified CTAB method. The psbA-trnH and rbcL sequences were gradient amplified, and PCR products were ligated with the pEASY-T5 vector and then transformed into Trans1-T1 cells, respectively. Clones were selected randomly and sequenced. All sequences were analyzed by BlastN and the neighbor-joining (NJ) phylogenetic tree was constructed by MEGA 4.0. The results showed that nine kinds of medicinal materials can be identified by psbA-trnH sequences, and six kinds of medicinal materials by rbcL sequences from Lian Qiao Bai Du Wan. Molecular marker technique can stably and accurately distinguish multi-origin medicinal materials in Chinese patent medicine.

Objective To OxplorO thO OffOct of N-tOrminal pro-brain natriurOtic pOptidO( NT-proBNP) combinOd with nOutrophil to lymphocytO ratio ( NLR) on short -tOrm prognosis in patiOnts with acutO ST sOgmOnt OlOvation myocardial infarction ( STEMI ) undOrgoing primary pOrcutanOous coronary intOrvOntion ( PCI ). Methods From January 2015 to DOcOmbOr 2016, 243 patiOnts with acutO STEMI who undOrwOnt primary PCI in Harrision IntOrnational POacO Hospital wOrO OnrollOd in thO study. ThO lOvOls of NT-proBNP and NLR wOrO mOasurOd at admission. ThO occurrOncO of major advOrsO cardiac and cOrObrovascular OvOnts(MACCE) was followOd up during 1 yOar aftOr PCI. ROcOivOr opOrating charactOristic( ROC) curvOs wOrO usOd to sOt cut-off valuOs of NT-proBNP and NLR for prOdicting MACCE. All patiOnts wOrO dividOd into 4 groups basOd on thO optimal cut-off point: low NT-proBNP/low NLR group, low NT - proBNP/high NLR group, high NT - proBNP/low NLR group, high NT-proBNP/high NLR group.

The establishment of a nutritional pathway is the premise and basis of nutritional therapy for patients with malignant tumor. The nasogastric tube, nasoenteric tube, and percutaneous endoscopic gastric/jejunostomy are commonly used clinical pathways for enteral nutrition (EN) therapy. However, these EN pathways are often difficult to establish in patients with malignant obstructive jaundice (MOJ) with pyloric or duodenum primary obstruction. For this reason, a new type biliary-intestinal nutrient tube placed through percutaneous transhepatic cholangiography drainage (PTCD) pathway was designed by the medical staff of hepatobiliary surgery department of Yinchuan First People's Hospital, and National Utility Model Patent of China were obtained (ZL 2020 2 0283951.5, ZL 2020 2 0288938.9). The new biliary-intestinal nutrient tube has two types: double-lumen tube and single-lumen tube, which consists of tube head, tube body, tail ring and developing ring. The double lumen tube realizes bile internal drainage and EN simultaneously through the double lumen structure of the tube body. The single-lumen tube is used for nutrient infusion after bile duct metal stent implantation, which is not limited by the type of nutrient solution. The tail ring of the two types of nutrient tube is placed in the upper jejunum to reduce retrograde infection and unexpected extubation. Compared with the prior art, the utility model has the advantages of simple structure, reasonable design, safe and effective placement through PTCD pathway, and opens up a new EN path for MOJ patients.

Objective:To analyze the clinical epidemiological characteristics and the prognostic risk factors of patients with hemorrhagic fever with renal syndrome (HFRS).Methods:A total of 2 245 HFRS patients who were admitted to the Second Affiliated Hospital of Air Force Medical University from September 2008 to December 2021 were enrolled. Clinical epidemiological data (including gender, age, onset season, onset region, case fatality rate, et al) of HFRS patients were analyzed. The clinical epidemiological characteristics of patients with HFRS in the 2008 to 2012, 2013 to 2017, and 2018 to 2021 groups were compared. Statistical comparisons were performed using chi-square test. The Bonferroni adjusted P-value method was used for pairwise comparisons between groups, and logistic regression analysis was used to screen and evaluate the risk factors associated with the prognosis of HFRS patients. Results:The age of 2 245 HFRS patients was (42.3±15.9) years old. Most of them were male (79.24%(1 779/2 245)), and the main incidence area was Xi′an City (69.53%(1 561/2 245)). There were 132 deaths with an overall case fatality rate of 5.88%. There were 1 088 patients (48.46%) from 2008 to 2012, 647 patients (28.82%) from 2013 to 2017, and 510 patients (22.72%) from 2018 to 2021, with a mortality rate of 7.17%(78/1 088), 5.10%(33/647) and 4.12%(21/510), respectively. From 2008 to 2021, both the number of HFRS cases and the case fatality rate had shown a fluctuating downward trend. There were significant differences in case fatality rate, age distribution, onset season, and onset region among patients in the different year groups ( χ2=6.84, 49.22, 83.47 and 19.29, respectively, all P<0.05). The results of pairwise comparisons showed that the proportion of patients aged >60 years in the 2018 to 2021 group (23.33%(119/510)) was higher than those in the 2008 to 2012 group (12.13%(132/1 088)) and the 2013 to 2017 group (12.36%(80/647)), and the differences were statistically significant (both P<0.05). The proportions of patients at large peak (October to December) were 62.35%(318/510) in the 2018 to 2021 group and 56.26%(364/647) in the 2013 to 2017 group, which were both lower than that in the 2008 to 2012 group (75.18%(818/1 088)), and the differences were both statistically significant (both P<0.05). The case fatality rate of patients aged >60 years was 9.67%(32/331), which was higher than those of patients aged <30 years (2.86%(16/559)) and patients aged 30 to 60 years (6.20%(84/1 355)), with statistically significant differences (both P<0.05). Univariate analysis showed that age 30 to 60 years, age >60 years, smoking, complicated with hypertension, hypotensive shock and hypoxemia were significantly correlated with the prognosis of HFRS patients (odds ratio ( OR)=2.243, 3.632, 1.484, 3.532, 79.422 and 143.955, respectively, all P<0.05). The results of multivariate logistic regression analysis indicated that complicated with hypertension ( OR=2.467, P=0.004), hypotensive shock ( OR=11.658, P=0.001), and hypoxemia ( OR=67.767, P<0.001) were the independent risk factors affecting the prognosis of HFRS patients. Conclusions:The prevalence of HFRS has shown new changing characteristics from 2008 to 2021. The numbers of HFRS patients and the case fatality rates show a downward trend, and the proportion of HFRS patients aged >60 years increases. Complicated with hypertension, hypotensive shock and development with hypoxemia are the independent risk factors for the prognosis of HFRS.

Non-Camellia tea is a part of the colorful Chinese tea culture, and is also widely used as beverage and medicine in folk for disease prevention and treatment. In this study, 37 samples were collected, including 33 kinds of non-Camellia teas and 4 kinds of teas (Camellia). Traditional functions of non-Camellia teas were investigated. Furthermore, non-Camellia teas of original plants were characterized and identified by molecular methods. Four candidate regions (rbcL, matK, ITS2, psbA-trnH) were amplified by polymerase chain reaction. In addition, DNA barcodes were used for the first time to discriminate the commercial non-Camellia tea and their adulterants, and to evaluate their safety. This study showed that BLASTN and the relevant phylogenetic tree are efficient tools for identification of the commercial non-Camellia tea and their adulterants. However, some sequences from original plants have not been found and there is a limitation of sequence number of original plants in GenBank. Submitting more original plant sequences to the GenBank will be helpful for evaluating the safety of non-Camellia teas.
