Methods Descriptive epidemiological analysis was used to analyze the epidemic characteristics and influencing factors of elderly (this article studies elderly people aged 65 and above) pulmonary tuberculosis in Xianning City, Hubei Province from 2011 to 2021. Results From 2011 to 2021, the average annual registration rate of elderly patients with pulmonary tuberculosis in Xianning City, Hubei Province was 211.52/100 000 (5 289/2 500 496), which showed a downward trend (χ2 trend=58.06, P<0.05), and significantly higher than the average registration rate of 96.04/100 000 patients with pulmonary tuberculosis (26 463/27 554 195)(χ2=2 896.69, P<0.05). The average proportion of the registered number of elderly patients with pulmonary tuberculosis in the whole population was 19.99% (5 289/26 463), which showed an upward trend (χ2trend=272.05, P<0.05). The average positive rate of etiology in elderly patients with pulmonary tuberculosis was 51.86% (2 743/5 289), which was significantly higher than that in the whole population 46.41% (12 282/26 463) (χ2=52.53, P<0.05). The average proportion of retreated patients in elderly patients with pulmonary tuberculosis was 8.92% (472/5 289), which was significantly higher than that of retreated patients in the whole population 6.33% (1 674/26 463) (χ2=47.23, P<0.05). The sex ratio of male to female in elderly patients with pulmonary tuberculosis was 2.92∶1. Among the six counties (districts) under the jurisdiction of Xianning City, Hubei Province the registration rate of elderly tuberculosis patients in Xian'an district was the highest 262.20/100 000 (1 267/483 220), and that in Tongcheng County was the lowest 123.83/100 000 (575/464 338), with significant differences (χ2=233.67, P<0.05). Conclusion The overall incidence of tuberculosis in the elderly in Xianning City , Hubei Province showed a downward trend, but the proportion of the incidence of tuberculosis in the elderly in the whole population has increased year by year, suggesting that the elderly are the key population of tuberculosis prevention and control in Xianning City in the future, and comprehensive prevention and control measures should be taken to reduce the incidence of tuberculosis in the elderly population.

@#Abstract: Objective To analyze the resistance and spatial distribution of Mycobacterium tuberculosis (MTB) to six commonly used anti-tuberculosis drugs in Qinghai Province from 2016 to 2019, so as to provide a reference for tuberculosis treatment and drug-resistant tuberculosis control. Methods A total of 1 182 identified strains of Mycobacterium tuberculosis in Qinghai Province from 2016 to 2019 were collected, and 6 anti-tuberculosis drugs were subjected to drug susceptibility tests and strain confirmed by the proportional method. By means of ArcMap10.7 and SaTScan10.1 software, map visualization, spatial autocorrelation analysis and spatial scanning of MTB drug resistance were performed to identify MTB drug resistance clusters in Qinghai Province. Results From 2016 to 2019, the total drug resistance (TDR) rate of 1 182 Mycobacterium tuberculosis strains in Qinghai Province was 23.77% (281/1 182), with a mono-resistance (MR) rate of 11.08% (131/1 182), a poly-resistance (PDR) rate of 3.89% (46/1 182), a multi-drug resistance (MDR) rate of 8.80% (104/1 182), and an extensive drug resistance (XDR) rate of 0.85% (10/1 182). The rates of MDR, XDR and TDR all showed a decreasing trend year by year (P<0.01). The drug resistance spectrum displayed 21 combinations. The TDR rate and MDR rate in the retreatment patients were higher than those of the initial treated patients, and the difference was statistically significant (χ2 TDR=22.784, χ2MDR=45.082, P<0.01). In terms of demographic characteristics, the TDR rate in males was higher than that in females, and the middle-aged group was higher than other age groups, and the differences were statistically significant (χ2=7.541, 10.825, P<0.05). The results of global spatial autocorrelation analysis showed that there was no statistical significance in the autocorrelation and obvious spatial clustering of MTB drug resistance in Qinghai Province from 2016 to 2019 (P>0.05), which indicated a random distribution. The results of spatiotemporal scanning showed that there was a kind of clustering area, but the clustering effect was not significant (P>0.05), indicating a random distribution. Conclusions The TDR of MTB in Qinghai Province from 2016 to 2019 showed a downward trend year by year. In comparison with the national average, the rate of multi-drug resistance and extensive drug resistance was still high, and most of the multi-drug resistance resulted from rifampicin and isoniazid. The drugresistant population mainly consisted of retreatment, males, and young and middle-aged pop

RESUMO
Poly (l-glutamic acid)-Combretastatin A4 conjugate (PLG-CA4) is a novel nano-anticancer drug. For macromolecule conjugate nanomedicine, its pharmacology mechanism is closely related to the pharmacokinetic profiles in vivo. It is a great significance that evaluates this polymer drug combined by covalently bound via studying the pharmacokinetics and distribution characteristics. Therefore, it is urgent to develop a simple, accurate and practical analytical method for such conjugated polymers combined by covalently bound. In this study, a simple and complete alkali hydrolysis was designed and optimized for the total CA4 concentrations obtained from PLG-CA4. Ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method with multiple-reaction monitoring (MRM) mode and the internal standard (IS) were adopted to develop a sensitive and accurate method satisfied both free and total determination of PLG-CA4 in biosamples. The method was validated which showed good linearity over a wide concentration range (R2 > 0.99), and the intra- and inter-day assay variability was less than 15% for CA4. The mean extraction recoveries of CA4 from plasma were all more than 80.0%. Furthermore, the method was applied to the study of pharmacokinetics (PK) and tissue distribution of PLG-CA4 in tumor-bearing nude mice. PLG-CA4 significantly prolonged retention time and enhanced distribution of CA4 in tumor.

Keke capsule as a traditional Chinese medicine formulation is used to relieve cough, for analgesia and to reduce bronchial asthma. The multi-components are absorbed into the blood and brain after oral administration of Keke capsule, with no systematic investigation so far. A reliable and rapid UPLC-QTOF-MSE combined with a data processing software platform was used to characterize the components of Keke capsule and simultaneously identify bioactive components in blood and brain tissues in rat after oral administration. Consequently, a total of 41 components of Keke capsule, including alkaloids, flavone, flavonols, triterpene, lignanoid, organic acids, glycosides and coumarin were identified. Twenty-one components were found in plasma, including 18 prototypes and three metabolites; 15 components were found in brain tissues, including 10 prototypes and five metabolites. Alkaloids and flavonoids in Keke capsule were the main components which were absorbed into blood. The main alkaloids of Keke capsule can pass through the blood-brain barrier and show different distribution tendencies in brain tissues. The main components of keke capsule was simultaneously analyzed by throughput analysis, and the corresponding bioactive components were examined by blood-brain barrier in the rat after oral administration of the capsule.

Phenylethanoid glycosides are the bioactive components in Monochasma savatieri that primarily contains savaside A, acteoside, and isoacteoside. Pharmacological research has been comprehensive, but there have been few studies on pharmacokinetics, especially about savaside A. An ultra high performance liquid chromatography with tandem mass spectrometry with multiple reaction monitoring mode was developed and validated for the simultaneous determination of the three compounds from M. savatieri. Meanwhile, this method was fully validated and successfully applied to compare the pharmacokinetics and bioavailability following four different routes included intravenous injection, intraperitoneal injection, muscle injection, and oral administration. The results indicated that the three compounds could be rapidly absorbed within 1 h, and the main pharmacokinetic parameters showed significant differences (P < 0.05). The bioavailability of oral administration, intramuscular injection, and intraperitoneal injection did not exceed 0.2, 25, and 10%, respectively. Comparing the bioavailability, it exhibited that acteoside > isoacteoside > savaside A following the four administration routes. Notably, the isomerization position of acteoside and isoacteoside mainly occurred in the liver according to the pharmacokinetics profiles of intraperitoneal and intravenous injection, in addition, isoacteoside exhibited more structural selectivity than acteoside in vivo. It demonstrated that three compounds undergo different processes, mainly affected by the first-pass effect and their intestinal stability is extremely poor.

Currently the pharmacokinetic (PK) research of herbal medicines is still limited and facing critical technical challenges on quantitative analysis of multi-components from biological matrices which often accompanied by lacking of authentic standards and low concentration. This present work contributes to the development of an integrated strategy for extensive pharmacokinetics assessments, and a selective and sensitive method independent of authentic standards for multi-components analysis based on the use of ultra-performance liquid chromatography/quadrupole-time-of-flight/MSE (UPLC-TOF-MSE) and UPLC-TOF-MRM (rnhanced target). Initially, phytochemicals were identified by UPLC-TOF-MSE analysis, subsequently the identified components were matched with authentic standards and pre-classified, and UPLC-QTOF-MRM method optimized and developed. To guarantee reliable results, three rules are necessary: (1) detection with a mass error of less than 5ppm; (2) same class chemical compositions with structural high similarity between analytes with and without authentic reference substance; (3) a matching retention time between TOF-MRM mode and TOF-MSE within 0.2min. The developed and validated method was applied for the simultaneous determination of 12 lignans in rat plasma after administered with wine processed Schisandra Chinensis fructus (WPSCF) extract. Such an approach was found capable of providing extensive pharmacokinetic profiles of multi-components absorbed into blood after oral administrated with WPSCF extract. The results also indicated that significant difference in pharmacokinetics parameters of dibenzocyclooctadiene lignans was observed between schizandrin and gomisin compounds. For lignans, the absorption via gastrointestinal tract were all rapid and maintained relatively long retention time, especially for schisantherin A and schisantherin B with higher plasma exposure.

A novel method for quantitation of cardiac muscle carnosine levels using HPLC-UV is described. In this simple and reliable method, carnosine from the rat cardiac muscle and the internal standard, thymopentin, were extracted by protein precipitation with acetonitrile. The method was linear up to 60.96 µg·mL(-1) for L-carnosine. The calibration curve was linear in concentration ranges from 0.5 to 60.96 µg·mL(-1). The relative standard deviations obtained for intra- and interday precision were lower than 12% and the recoveries were higher than 90% for both carnosine and internal standard. We successfully applied this method to the analysis of endogenous carnosine in cardiac muscle of the diabetes rats and healthy control rats. The concentration of carnosine was significantly lower in the diabetes rats group, compared to that in the healthy control rats. These results support the usefulness of this method as a means of quantitating carnosine and illustrate the important role of L-carnosine in cardiac muscle.
RESUMO
This study was performed to use UHPLC-QTOF/MSE technology to rapidly search and identify variations of chemical ingredients between Fructus Schisandrae Chinensis and its processed products. The present study provides a basis for the study of Chinese herbal medicine processing with a focus on the impact of processing on chemical components. Using a time-dependent data scan mode (MSE) couple with metabolomics technology, we acquired accurate data and identified the potential chemical markers. A total of 12 chemical markers were identified in the crude, vinegar-processed and wine-processed Schisandra chinensis fruit; The results showed that the levels of 6-O-benzoylgomisin O, schisantherin B, schisantherin C, schisantherin D and neokadsuranic acid are the highest in crude Schisandra chinensis fruit; thelevels of schizandrin A, schizandrin B, schizandrin C, gomisin D and gomisin T are the highest in wine-processed Schisandra chinensis fruit; the levels of schisantherin A and schisandrin are the highest in vinegar-processed Schisandra chinensis fruit. There were significant changes of chemical components between Fructus Schisandrae Chinensis and their processed products, and these findings may offer a reasonable explanation for variation of efficacy and clinical applications in the processed products of Fructus Schisandrae Chinensis.

Pulsatilla chinensis, a traditional Chinese medicine (TCM), has been used for treating amoebic diseases, vaginal trichomoniasis and bacterial infections over a long history. Now growing attention has been attracted to its antitumor activities. The purpose of this work was to compare the pharmacokinetic profiles of pulchinenosides in different formulations and to improve their oral bioavailability. Extracts of P. chinensis saponins were prepared for PRS-Na (salt forming), PRS-HPßCD (hydroxypropyl-ß-cyclodextrin inclusion complex), PRS-O/W (oil-in-water emulsion) and PRS-silica (micronization), respectively. A simpler and more durable LC-MS/MS method was developed in this study for quantitative analysis of pulsatilla sapoin D, B7, B10, B11 and sapoin PD simultaneously. The four formulations enhanced saponins oral bioavailability to varying degrees, as PRS-HPßCD > PRS-silica > PRS-O/W > PRS-Na, which indicated that water-soluble preparations can obviously improve the solubility of saponins, and are helpful to increase bioavailability. In particular, hydroxypropyl-ß-cyclodextrin inclusion complex was the most effective way to promote absorption of saponins, raising the F values (bioavailability) >20 times. Therefore, P. chinensis saponin molecules can be slowly released by emulsion and micronization, which can avoid the enormous Cmax appearing in HPßCD, considering the pharmacokinetics profiles. However, appropriate pharmacokinetic parameters were observed in PRS-Na, although the F value was minimum among the four preparations.

Viral disease is a calamity which absolutely can not be ignored for human health. The emergence of drug resistance and spread of new virus will be the new challenge against viral disease. To find and develop new antivirus agents with properties of safety, significant effect and low toxicity is the pressing question facing humans today. Because of its advantages, including rich resources, low price, less adverse effect, Traditional Chinese medicine (TCM) have become the research focus in antiviral treatment. In recent years, there are numerous articles about the studies from separation of active ingredients to the antiviral mechanism. In this paper, the progress in experimental study was illustrated on the basis of active ingredients, species of virus, mechanism, clinical application. Obviously, TCM have obvious advantages in the treatment of virus infectious disease and has a broad prospect of application.

Neurofibromas arise from peripheral nerve cells. They are rarely found within the pancreas, especially not associated with type I neurofibromatosis. Here, we report a case of a neurofibroma in a 44-year-old woman who initially presented with epigastralgia. Imaging revealed one large cystic mass of 5.7 × 8 × 5.8 cm in the pancreatic body, which was resected with distal pancreatectomy. The postoperative course of treatment was without complication, and no signs of recurrence were observed after 1 year and 6 months' follow-up.

BACKGROUND: Pericardial effusion occurs frequently in patients with hypothyroidism and is typically mild. Although extremely uncommon, massive pericardial effusion can compromise hemodynamics and cause cardiac tamponade. Reduced plasma volume has been reported to induce cardiac tamponade in massive pericardial effusion, but to our knowledge, hypovolemia-induced cardiac tamponade has not been reported in cases of hypothyroidism with pericardial effusion. OBJECTIVES: We describe a case of hypothyroidism with cardiac tamponade due to an uncommon cause that, to our knowledge, has never been reported. CASE REPORT: A 64-year-old woman with untreated hypothyroidism presented with acute abdominal pain and watery diarrhea. The patient experienced shock and cardiac arrest during the examination. Massive pericardial effusion was detected and cardiac tamponade was diagnosed. We suspected that the pericardial effusion was pre-existing due to an 11-year history of untreated hypothyroidism. On presentation, there was no hemodynamic compromise. Watery diarrhea persisted and intravenous fluid supplementation may have been inadequate. Hypovolemia developed and induced cardiac tamponade in the presence of the massive pericardial effusion. Successful resuscitation was achieved after cardiopulmonary resuscitation, aggressive intravenous fluid supplementation, and immediate pericardiocentesis. CONCLUSION: Pericardiocentesis is indicated for hypothyroid patients with cardiac tamponade. We recommend the use of small, multi-hole catheters and daily measurement of drainage fluid. If the pericardial effusion does not resolve, a pericardial window with chest tube drainage should be performed.

INTRODUCTION: The axillary nerve can be injured during external skeletal fixation with Schanz screws or proximal locking screws of intramedullary nails. Being aware of the axillary nerve's anatomic relationship to the proximal humerus is vital for avoiding complications. METHODS: We investigated the relationship of the axillary nerve to surrounding bony landmarks by studying 88 axillary nerves in 44 embalmed cadaveric adult Chinese males. These measurements were then compared with the results from a similar study among Caucasians using the same reference points. RESULTS: We identified three significantly different parameters between our Chinese and the previously studied Caucasian subjects (P ≤ 0.05): the distances from the superior aspect of the humeral head to the axillary nerve (D1) (5.2 ± 0.7 vs. 6.09 ± 0.65 cm, respectively); surgical neck to axillary nerve (D2) (2.0 ± 0.7 vs. 1.72 ± 0.84 cm); and humeral length (D3) (29.0 ± 2.2 vs. 35.25 ± 5.7 cm). The D1 distance ranged from 4.0 to 6.7 cm; the D2 distance ranged from 1.0 to 4.1 cm; and the entire humeral length (D3) ranged from 23.3 to 33.3 cm. Iatrogenic injury to the axillary nerve could be reduced by placing pins and screws in proper directions using portable C-arm fluoroscopic guidance, drill-guided protective systems, and a mini-open-incision with muscle spreading and drill protective systems directly placed on the bone. CONCLUSION: Because of physical variability among individual patients and populations, surgeons should consider the possible courses of the axillary nerve when treating proximal humeral fractures.

Aortic perforation caused by the friction of a chest tube is a rare but life-threatening complication of coronary artery bypass grafting (CABG). We report a case involving CABG for triple-vessel disease and unstable angina. Reexploration was necessary 24 hours after the operation because of the sudden onset of pronounced bleeding. Perforation of the ascending aorta caused by friction of the chest tube was found. Bleeding was controlled by means of a purse string suture with 4-0 Prolene. Use of pericardium membrane between the heart and the chest tube and the choice of smaller and more flexible Silastic chest tubes in high-risk patients can probably reduce the incidence of this complication.

Infectious complications are the top causes of morbidity and mortality in patients who undergo renal transplantation. We report a patient who received a cadaveric renal transplant in Mainland China. One year post-transplantation, the patient had right buttock pain with radiation to the leg. Swelling and tenderness over the right groin was also found. Magnetic resonance imaging revealed a multilobulated cystic lesion, about 8 x 7 cm, at the right iliac fossa and presacral region extending to the posterior aspect of the graft kidney and up to the right psoas muscle. Drainage of the intra-abdominal abscess was performed. The abscess culture showed presence of Aspergillus spp. The patient had received steroids, tacrolimus and mycophenolate mofetil, which could be a risk factor for fungal infection. The cause of Aspergillus infection in our patient remains unclear. It may have been due to immune system insufficiency of the patient rendering the patient prone to infection. Pseudoaneurysm formation of the internal iliac artery following Aspergillus infection after kidney transplantation is rarely reported. Although it is a dilemma, once a severe situation such as pseudoaneurysm with aspergillosis presents, graft removal is suggested.

BACKGROUND: The quality and outcome of health care administered in intensive care units (ICUs) of teaching hospitals are dependent on a myriad of factors; however, few studies have assessed mortality rates and length of stay in surgical intensive care and neurologic intensive care units (SICU/NICU) in relation to the experience of junior and senior surgery residents. OBJECTIVE: The aim of this study was to determine whether there were differences in the outcomes of ICU patients cared for by junior surgery residents or senior surgery residents by assessing mortality rates and length of stay in the SICU/NICU. DESIGN: This was a retrospective cohort analysis. Mortality rates, length of SICU/NICU stay, and baseline characteristics were assessed in 2 patient groups: group 1, patients managed by junior surgical residents; group 2, patients managed by senior surgical residents. Categorical variables were compared by chi(2)/Fisher exact test, and continuous data (age and ICU stay) were compared using the Mann-Whitney U test. Acute Physiology and Chronic Health Evaluation II score was used for ICU prognostic models. SETTING: The Taoyuan Armed Forces General Hospital (Taoyuan, Taiwan, ROC) consists of an 8-bed SICU and an 8-bed NICU. PATIENTS: Data were collected from 2274 patients from January 1, 2002, to December 31, 2006, from the intensive care units (SICU/NICU) of the department of surgery. INTERVENTIONS: None. RESULTS: Significant differences between the 2 groups were found in total patient mortality and the duration of intensive care unit stay. Of 1806 patients in group 1, 446 (24.7%) died, whereas 83 (17.7%) of 468 in group 2 died (P = .002). The major difference of mortality rate was in the division of neurology surgery; 291 (26.6%) of 1092 patients in group 1 died, whereas 55 (19.2%) of 287 in group 2 died (P = .009), with most deaths due to spontaneous intracranial hemorrhage (P = .012) and central nervous system tumors (P = .048). Median length of SICU/NICU stay for group 1 was 3.0 days vs 3.5 days for group 2 (P = .003). CONCLUSIONS: The quality of care of critically ill patients is improved when more experienced residents are providing care. We suggest that residents rotated into the special units such as SICU/NICU for care of critically ill patients should be at least at third year of training.

A 79-year-old previously healthy man presented with acute acalculous cholecystitis with obstruction of the biliary tract. He was successfully treated with antibiotics and percutaneous transhepatic gallbladder drainage, but returned to the hospital two days after discharge with a rare complication of this technique, biliopleural fistula. A thoracostomy tube was inserted to drain the pleural effusion, and the patient's previous antibiotics reinstated. After two weeks of drainage and antibiotics, the fistula healed spontaneously without the need for further intervention.

BACKGROUND: Coronary artery fistulas are uncommon abnormalities that can cause significant cardiac morbidity. Indications for operation vary, particularly, for asymptomatic patients. Early surgical correction is indicated because of the high incidence of late symptoms and complications. METHODS: From January 1981 to December 2001, all 15 patients who underwent surgical management of congenital coronary artery fistulas at the Tri-Service General Hospital, Taipei, Taiwan, China were included in the present retrospective study. RESULTS: Twelve patients were symptomatic at the time of the diagnosis. Coronary artery fistulas involved the right coronary artery in five patients, left coronary artery in nine, and both the right and the left coronary arteries in one. Coronary artery fistula drained into the right ventricle in seven patients, right atrium in three, pulmonary artery in two, left ventricle in one, left atrium in two, and coronary venous sinus in one. The value of pulmonary blood flow/systemic blood flow ranged from 0.98 to 2.1. Six patients had associated cardiac anomalies. All patients received surgical correction. Nine patients received cardiopulmonary bypass during operation. There was zero operative mortality and operative morbidity was low. All patients had a stable condition and were asymptomatic during a mean postoperative follow-up of 13.3 years. CONCLUSIONS: Early surgical treatment for coronary artery fistulas is safe and effective. The risk of operative correction appears to be considerably less than the potential for development of serious and potentially fatal complications, even in asymptomatic patients.
