ABSTRACT

Objective:To evaluate liver functional reserve in healthy subjects of different age groups using the L-[1- 13C]-phenylalanine breath test( 13C-pheBT)and to investigate the patterns of changes in liver functional reserve with aging in comparison with elderly cirrhosis patients. Methods:Thirty-seven healthy volunteers were divided into a young and middle-aged group(n=10), an early elderly group(n=9), an advanced elderly group(n=9)and a longevity group(n=9). Eight elderly patients with liver cirrhosis were selected as the control group.An oral dose of 100 mg 13C-phe was administered to each subject.Expired breath samples were collected at pre-dose and at 12 different time points within 150 minutes post-dose.Isotope ratio mass spectrometer was used to measure the abundance of 13C.The percentage of the 13C excretion rate( 13CO 2ERt), the percentage of 13C cumulative excretion( 13Ccumt)at different time points, and the percentage of the 13C peak excretion rate( 13CO 2ERmax)after drug administration were calculated.In addition, associations between 13C-pheBT and common liver function parameters were analyzed. Results:Compared with healthy volunteers, 13CO 2ER 30, 13CO 2ER 45, 13CO 2ER 60, 13Ccum 45, 13Ccum 60, 13Ccum 75, 13Ccum 90 and 13Ccum 105, 13Ccum 120, 13Ccum 135, 13Ccum 150 showed significant differences in the longevity group, the young and middle-aged group and the young elderly group.There were statistically significant differences between the elderly cirrhosis group and the healthy volunteers in each subgroup(all P<0.05); The mean values of 13CO 2ERmax, 13CO 2ER 30, 13Ccum 45, 13Ccum 60, 13Ccum 75, 13Ccum 90, 13Ccum 105, 13Ccum 120, 13Ccum 135, 13Ccum 150 decreased following the order of the young and middle-aged group, the early elderly group, the advanced elderly group, the longevity group, and the elderly cirrhosis group(all P<0.05). In healthy volunteers, the 13CO 2 exclusion rate curve and the cumulative exclusion rate curve showed that the curves of the young and middle-aged group and the early elderly group almost overlapped, while the curves of the advanced group and the longevity group decreased with age, and the difference between the longevity group and the young and middle-aged group and between the longevity group and the early elderly group was markedly prominent. Conclusions:13C-pheBT is a safe, sensitive and reliable test for quantitation of liver function.Our recommendations include collecting samples within an hour of drug administration and using 13CO 2ERmax, 13CO 2ER 30, 13Ccum 45 and 13Ccum 60 as the main parameters.Overall, the functional reserve and compensatory capability of the liver are robust.The decline in liver functional reserve in healthy individuals is a gradual and slow process, with a significant decrease after age 80 and more so after age 90.

ABSTRACT

Objective: To compare the effectiveness of total laparoscopic versus laparoscopic-assisted distal gastrectomy and investigate the safety and replicability of total laparoscopic distal gastrectomy in older patients. Methods: This was a retrospective cohort study. The inclusion criteria were as follows: (1) age ≥65 years; (2) malignant gastric tumor diagnosed pathologically preoperatively; (3) Eastern Cooperative Oncology Group performance status score 0-1; (4) Grade I-III American Society of Anesthesiologists physical status; (5) preoperative clinical tumor stage I-III; (6) total laparoscopic or laparoscopic-assisted distal gastrectomy performed; and (7) gastrointestinal tract reconstruction using uncut Roux-en-Y or Billroth-II+Braun procedure. Patients who had received neoadjuvant therapy, undergone conversion to open surgery, or had serious comorbidities or incomplete data were excluded. The clinical data of 129 patients who met the above criteria and had undergone laparoscopic surgery for gastric cancer from January 2012 to December 2021 in the Gastrointestinal Cancer Center in the Beijing Cancer Hospital were analyzed. According to the operation method, the patients were divided into total laparoscopic group and laparoscopic-assisted group. Variables studied comprised: (1) surgical procedure and postoperative recovery; (2) postoperative pathological findings; and (3) postoperative complications. Measurement data with skewed distribution are represented as mean(quartile 1, quartile 3). Comparisons between groups were evaluated using the Mann-Whitney U test. Results: After propensity score matching in a 1:1 ratio, there were 40 patients in the total laparoscopic distal gastrectomy group and 40 in the laparoscopic-assisted distal gastrectomy group. Baseline characteristics did not differ significantly between the two groups (all P>0.05).Compared with the laparoscopic-assisted group, the total laparoscopic group had shorter main incisions (4.1±1.0 cm vs. 8.5±2.8 cm, t=9.375, P<0.001), time to fluid intake [4.0 (3.0, 4.8) days vs. 5.0 (4.0, 6.0) days, Z=2.167, P=0.030], and duration of indwelling abdominal drainage catheter [6.0 (6.0, 7.0) days vs. 7.0 (6.0, 8.0) days, Z=2.323, P=0.020]. Numerical Rating Scale scores on postoperative days 1 and 2 were higher in the total laparoscopic than the laparoscopic-assisted group [2.5 (1.0, 3.0) vs. 1.5 (1.0, 2.0), Z=1.980, P=0.048; 2.0 (1.0, 3.0) vs. 1.0 (1.0, 2.0), Z=2.334, P=0.020, respectively]. However, there were no significant differences between the groups in operation time, intraoperative blood loss, white blood cell count, hemoglobin concentration, or albumin concentration on postoperative day 1, time to ambulation, mean time to bowel movement, postoperative admission to the intensive care unit, length of postoperative hospital stay, or Numerical Rating Scale scores on postoperative day 3 (all P>0.05). There were also no significant differences between the two groups in maximum tumor diameter, pathological tumor type, total number of lymph nodes dissected, or total number of positive lymph nodes (all P>0.05). The incidence of postoperative complications was 15.0% (6/40) in the total laparoscopic group and the laparoscopic-assisted group; these differences are not significant (χ2<0.001, P>0.999). Conclusions: Compared with laparoscopic-assisted radical gastrectomy for distal gastric cancer, total laparoscopic surgery has the advantages of shorter incision, shorter time to fluid intake, and shorter duration of indwelling abdominal drainage catheter in older patients (age ≥65 years). Total laparoscopic radical gastrectomy for distal gastric cancer does not increase the risk of postoperative complications and could therefore be performed more frequently.

ABSTRACT

Post-amputation pain causes great suffering to amputees, but still no effective drugs are available due to its elusive mechanisms. Our previous clinical studies found that surgical removal or radiofrequency treatment of the neuroma at the axotomized nerve stump effectively relieves the phantom pain afflicting patients after amputation. This indicated an essential role of the residual nerve stump in the formation of chronic post-amputation pain (CPAP). However, the molecular mechanism by which the residual nerve stump or neuroma is involved and regulates CPAP is still a mystery. In this study, we found that nociceptors expressed the mechanosensitive ion channel TMEM63A and macrophages infiltrated into the dorsal root ganglion (DRG) neurons worked synergistically to promote CPAP. Histology and qRT-PCR showed that TMEM63A was mainly expressed in mechanical pain-producing non-peptidergic nociceptors in the DRG, and the expression of TMEM63A increased significantly both in the neuroma from amputated patients and the DRG in a mouse model of tibial nerve transfer (TNT). Behavioral tests showed that the mechanical, heat, and cold sensitivity were not affected in the Tmem63a-/- mice in the naïve state, suggesting the basal pain was not affected. In the inflammatory and post-amputation state, the mechanical allodynia but not the heat hyperalgesia or cold allodynia was significantly decreased in Tmem63a-/- mice. Further study showed that there was severe neuronal injury and macrophage infiltration in the DRG, tibial nerve, residual stump, and the neuroma-like structure of the TNT mouse model, Consistent with this, expression of the pro-inflammatory cytokines TNF-α, IL-6, and IL-1β all increased dramatically in the DRG. Interestingly, the deletion of Tmem63a significantly reduced the macrophage infiltration in the DRG but not in the tibial nerve stump. Furthermore, the ablation of macrophages significantly reduced both the expression of Tmem63a and the mechanical allodynia in the TNT mouse model, indicating an interaction between nociceptors and macrophages, and that these two factors gang up together to regulate the formation of CPAP. This provides a new insight into the mechanisms underlying CPAP and potential drug targets its treatment.

ABSTRACT

To explore the effect of Mlk3 (mixed lineage kinase 3) deficiency on blood pressure, Mlk3 gene knockout (Mlk3KO) mice were generated. Activities of sgRNAs targeted Mlk3 gene were evaluated by T7 endonuclease I (T7E1) assay. CRISPR/Cas9 mRNA and sgRNA were obtained by in vitro transcription, microinjected into zygote, followed by transferring into a foster mother. Genotyping and DNA sequencing confirmed the deletion of Mlk3 gene. Real- time PCR (RT-PCR), Western blotting or immunofluorescence analysis showed that Mlk3KO mice had an undetectable expression of Mlk3 mRNA or Mlk3 protein. Mlk3KO mice exhibited an elevated systolic blood pressure compared with wild-type mice as measured by tail-cuff system. Immunohistochemistry and Western blotting analysis showed that the phosphorylation of MLC (myosin light chain) was significantly increased in aorta isolated from Mlk3KO mice. Together, Mlk3KO mice was successfully generated by CRISPR/Cas9 system. MLK3 functions in maintaining blood pressure homeostasis by regulating MLC phosphorylation. This study provides an animal model for exploring the mechanism by which Mlk3 protects against the development of hypertension and hypertensive cardiovascular remodeling.

ABSTRACT

In order to provide the basis for the development of famous classical formulas containing Myrrha, the name, origin, quality evaluation, harvest and processing of Myrrha were systematically researched by consulting the ancient herbal and medical books, combining with the modern related literature. According to textual research, the results showed that Commiphora myrrha was the main base in ancient times, which was produced in Somalia, Ethiopia and northern Kenya. In addition, raw and fried products of Myrrha were the commonly used specifications in ancient herbal medicine, which are still used today. Nowadays, Myrrha, fried Myrrha and vinegar-processed Myrrha were the commonly used specifications. Among the three specifications, Myrrha is the raw products after cleaning, fried Myrrha is a kind of processed products, which has relevant records in ancient materia medica and is still used today. Vinegar-processed Myrrha is a new processing specification in modern times. Based on the research results, it is suggested that Myrrha in Shentong Zhuyutang should be the purified raw Myrrha in accordance with the 2020 edition of Chinese Pharmacopoeia.

ABSTRACT

Cytochrome P450 (CYP46A1) is a central neuro-specific metabolic enzyme that converts cholesterol into 24-hydroxycholesterol. This metabolic process is the main mechanism of cholesterol elimination in brain and is closely related to the occurrence and development of neurodegenerative diseases. This review focuses on the relationship between CYP46A1 and neurodegenerative diseases, from the aspects of regulatory mechanism of CYP46A1 enzyme, the relationship between CYP46A1 and cognitive dysfunction, epileptic encephalopathy, and CYP46A1 enzyme activity modifiers (inhibitors and agonists) to illustrate the pivotal role of CYP46A1 in the development and prevention of neurodegenerative diseases in hope of providing new target and direction for the research and development of new drugs.

ABSTRACT

This study aims to explore the effects of arachidonic acid lipoxygenase metabolism in vascular calcification. We used 5/6 nephrectomy and high-phosphorus feeding to establish a model of vascular calcification in mice. Six weeks after nephrectomy surgery, vascular calcium content was measured, and Alizarin Red S and Von Kossa staining were applied to detect calcium deposition in aortic arch. Control aortas and calcified aortas were collected for mass spectrometry detection of arachidonic acid metabolites, and active molecules in lipoxygenase pathway were analyzed. Real-time quantitative PCR was used to detect changes in the expression of lipoxygenase in calcified aortas. Lipoxygenase inhibitor was used to clarify the effect of lipoxygenase metabolic pathways on vascular calcification. The results showed that 6 weeks after nephrectomy surgery, the aortic calcium content of the surgery group was significantly higher than that of the sham group (P < 0.05). Alizarin Red S staining and Von Kossa staining showed obvious calcium deposition in aortic arch from surgery group, indicating formation of vascular calcification. Nine arachidonic acid lipoxygenase metabolites were quantitated using liquid chromatography/mass spectrometry (LC-MS) analysis. The content of multiple metabolites (12-HETE, 11-HETE, 15-HETE, etc.) was significantly increased in calcified aortas, and the most abundant and up-regulated metabolite was 12-HETE. Furthermore, we examined the mRNA levels of metabolic enzymes that produce 12-HETE in calcified blood vessels and found the expression of arachidonate lipoxygenase-15 (Alox15) was increased. Blocking Alox15/12-HETE by Alox15 specific inhibitor PD146176 significantly decreased the plasma 12-HETE content, promoted calcium deposition in aortic arch and increased vascular calcium content. These results suggest that the metabolism of arachidonic acid lipoxygenase is activated in calcified aorta, and the Alox15/12-HETE signaling pathway may play a protective role in vascular calcification.

ABSTRACT

Objective:To optimize the blending method of Shuanghuanglian injection, and to investigate its stability in different solvents (0.9% sodium chloride injection, 5% glucose injection, 10% glucose injection, glucose and sodium chloride injection). Methods:By using orthogonal test to optimize the best dissolution method of Shuanghuanglian injection By measuring the content change of insoluble particles, pH value and principal components (baicalin, forsythione, chlorogenic acid) in the finished products to investigatethe stability of Shuanghuanglian injection in different solvents. Results:The optimal blending method of Shuanghuanglian injection was to add 5 ml sterilized water for injection into the vial and oscillate at 1 200 r/min frequency for 5 min. The main constituents of Shuanghuanglian injection were stable in 8 h in the infusion of four kinds of finished products. Insoluble particles in 0.9% sodium chloride infusion and 5% glucose infusion met the requirements within 8 h, and insoluble particles in 10% glucose infusion and 6 h glucose and sodium chloride infusion met the requirements. The pH value of 0.9% sodium chloride infusion within 8 h met the optimal requirements of the best compatibility, 5% glucose infusion within 2 h met the requirements, and 4 h sodium chloride infusion met the requirements of the best compatibility. Conclusion:This study optimized the best preparation method of Shuanghuanglian (freeze-dried) for injection. Sodium chloride injection should be used as the solvent to prepare finished infusion in clinical application, and 5% glucose injection should be prepared just before use.

ABSTRACT

Objective:To observe the possible toxicity of long-term intravenous injection of Tanreqing injection in Beagle dogs, so as to provide experimental data for its clinical safe medication. Method:A total of 32 Beagle dogs (16 males and 16 females) were randomly divided into the low- (2.5 mL·kg<sup>-1</sup>), medium- (5.0 mL·kg<sup>-1</sup>), and high-dose (10.0 mL·kg<sup>-1</sup>) Tanreqing injection groups and control group according to their body mass indices, with eight dogs in each group. In the waking state, the dogs were treated with intravenous injection of corresponding drugs into the medial cephalic vein of forelimb for 13 weeks, followed by four-week drug withdrawal. After the observation of general condition, body mass, and food consumption, the Beagle dogs were subjected to electrocardiography, ophthalmoscopy, hematological examination, serum biochemistry, and blood coagulation test in the middle of medication (week 6), at the end of medication (week 13), and during recovery (week 17). Then the gross anatomy was conducted for calculating the major organ coefficients and observing the histopathological changes. Result:No obvious toxic reaction was found in each group, but the decreased fibrinogen and increased Kupffer's cells phagocytizing yellow-brown pigment in hepatic sinusoids were observed in the high-dose Tanreqing injection group following three months of medication. Reduction of fibrinogen was not observed in recovery period, but Kupffer's cells that phagocytized yellow-brown pigment still existed. Conclusion:The intravenous injection of Tanreqing injection at 2.50 mL·kg<sup>-1 </sup>(low dose), 5.00 mL·kg<sup>-1</sup> (medium dose) or 10.00 mL·kg<sup>-1 </sup>(high dose) for three months in Beagle dogs resulted in no obvious toxic reaction. However, it is still suggested to test the liver function and blood coagulation after long-term administration of high-dose Tanreqing injection.

ABSTRACT

Objective:To observe the effect of microelectronic EMG bridge (EMGB) training on the motor function of extensor carpi radialis longus in patients with complete cervical 5 spinal cord injury. Methods:From March, 2016 to March, 2017, 20 patients with complete cervical 5 spinal cord injury were randomly divided into control group (n = 10) and experimental group (n = 10). The control group received routine wrist extensor muscle training, and the experimental group received EMGB training in addition, for 180 days. The motor function of the affected limb was evaluated by sEMG of extensor carpi radialis longus, Manual Muscle Test (MMT), Wolf Motor Function Test (WMFT) and Spinal Cord Lesion Independence Measure (SCIM). Results:After treatment, the peak value and average value of sEMG of extensor carpi longus of both sides increased in both groups (t > 2.510, P < 0.05), the peak value and average value of the left side were higher (t > 2.759, P < 0.05), and the peak value of the right side was higher (t = 2.691, P < 0.05) in the experiment group than in the control group, however, there was no significant difference in average value of the right side between two groups (t = 2.063, P = 0.054). The scores of MMT increased in both groups (t > 2.569, P < 0.05), and were higher in the experimental group than in the control group (t > 2.278, P < 0.05). The scores of WMFT and SCIM increased in both groups (t > 3.839, P < 0.05), however, there was no significant difference between two groups (t < 1.498, P > 0.05). Conclusion:EMGB training could improve the motor function of extensor carpi radialis longus in patients with complete cervical 5 spinal cord injury.

ABSTRACT

ABSTRACT OBJECTIVE:To determine the suitable storage conditions,packaging materials and packaging methods of Ziziphi Spinosae Semen,and to provide reference for guaranteeing the quality. METHODS:The same batch of Ziziphi Spinosae Semen samples were packed in plastic woven bag,plastic bag,plastic bag in vacuum,aluminum-plastic composite bag,aluminum-plastic composite bag in vacuum and kraft coated paper bag. They were stored in a cool warehouse(temperature ≤20 ℃,relative humidity was 45%-75%) and drug stability test box [temperature was(40±2)℃,relative humidity was(75±5)%]. Five evaluation indexes were detected during 6-month of long-term cool stability test and accelerated stability test,including characters and the contents of moisture,aflatoxins,jujubosides A and spinosin. RESULTS:The results of 6-month long-term cool stability test showed that the character and the content of moisture,aflatoxins and jujubosides A of Ziziphi Spinosae Semen under different packaging conditions were in line with the requirements of 2015 edition of Chinese Pharmacopeia (part Ⅰ)(shorted for “pharmacopeia”). The content of spinosin didn’t meet the requirement of pharmacopeia(no less than 0.080%),but the content of spinosin(0.079%)of aluminum-plastic composite bag in vacuum was close to the requirements of pharmacopeia. The results of 6-month accelerated stability test showed that the sample packed in kraft coated paper bag and plastic woven bag were seriously moldy;the sample packed in plastic bag and plastic bag in vacuum were blackened;the color of the sample packed in aluminum-plastic composite bag was slightly darker;but the appearance of the sample packed in aluminum-plastic composite bag in vacuum was basically unchanged. Only when stored for 2-month,the content of aflatoxin B1 in the sample packed in plastic woven bag was 8.64 μg/kg,which exceeded the pharmacopoeia regulation. The moisture content of the sample packed in plastic woven bag and kraft coated paper bag exceeded the highest value (9.0%) required by the pharmacopoeia. Although the content of jujuboside A of samples in each package decreased,it meet the requirements of the pharmacopoeia. Only the content of spinosin (0.084%)of sample packed in plastic bag in vacuum meet the requirements of the pharmacopoeia,and the content of spinosin (0.071%)of sample packed in aluminum-plastic composite bag in vacuum was relatively high. CONCLUSIONS:Ziziphi Spinosae Semen should be stored in a cool and dry place after packed in aluminum-plastic composite bag in vacuum.

ABSTRACT

The incidence and proportion of traumatic spinal cord injury in the elderly are increasing year by year, and it has become the main affected population of spinal cord injury in developed countries. Fall is the main cause of injury. The increase of spinal stenosis, the biomechanical changes of the spine and the hyperextension injuries may be the mechanism of spinal cord injury caused by minor trauma in this population. Traumatic spinal cord injury in the elderly usually requires early surgical treatment. When there are complicated comorbidities, unstable vital signs or mild spinal cord injury without major fracture or dislocation, non-surgical treatment and active rehabilitation can be considered. However, the specific indications and timing of surgery are still controversial. Compared with young people, most elderly patients present with incomplete cervical spinal cord injury and are expected to restore better limb function, following poor recovery of self-care ability. It is important to monitor the functional change throughout rehabilitation and adjust the hours and intensity of training accordingly.
