Objective:To investigate the expression and significance of endoplasmic reticulum stress apoptosis pathway related proteins in renal cortex of rats with chronic fluorosis.Methods:Twenty four healthy SD rats were divided into 4 groups (6 rats/group, half male and half female) according to their body mass (100 - 120 g) by random number table method, rats in control group drank tap water (fluoride content < 0.5 mg/L), and in low, medium and high fluoride groups drank tap water with fluoride content (sodium fluoride) of 10, 50 and 100 mg/L, respectively. After 180 days of feeding, dental fluorosis was examined, 24-hour urine sample was collected and the content of fluoride in urine was detected by fluoride ion selective electrode method. Renal tissue was taken after anesthesia, and the pathological changes of renal cortex were observed by hematoxylin-eosin (HE) staining. The expressions of endoplasmic reticulum stress apoptosis pathway related proteins [inositol-requiring enzyme 1α (IRE1α), apoptosis signal-regulating kinase 1 (ASK1), C-Jun N-terminal kinase (JNK) and phosphorylated JNK (P-JNK)] were determined by immunohistochemical staining in rat renal cortex.Results:No dental fluorosis was found in control group. The incidence of dental fluorosis in low, medium and high fluoride groups were 2/6, 5/6 and 6/6, respectively. Compared with control group [(5.707 ± 1.190) mg/L], the urinary fluoride in low, medium and high fluoride groups [(17.028 ± 3.006), (34.378 ± 12.045), (94.759 ± 31.773) mg/L] was significantly higher ( P < 0.05), and the urinary fluoride in high fluoride group was higher than that in low and medium fluoride groups ( P < 0.05). HE staining showed that, compared with control group, the cell volume of renal tubules and glomeruli in medium and high fluoride groups increased, the cells arranged closely, and the eosinophilia of the cytoplasm increased. The immunohistochemical staining results showed that there was no significant difference in the expression of JNK protein in rat renal cortex between control group and low, medium and high fluoride groups ( F = 0.07, P > 0.05). The expressions of IRE1α, ASK1 and P-JNK proteins in rat renal cortex in high fluoride group were higher than those of control, low and medium fluoride groups ( P < 0.05), and the expressions of IRE1α and ASK1 proteins in medium fluoride group were significantly higher than those in control and low fluoride groups ( P < 0.05). Conclusion:Long-term excessive fluoride intake can lead to renal cortex injury in rats, and the mechanism of injury may be related to the activation of IRE1α-ASK1-JNK endoplasmic reticulum stress apoptosis pathway.

Objective:To investigate the effect of Da Vinci robot-assisted single-port plus-one laparoscopic pyeloplasty (RSPY) in children with ureteropelvic junction obstruction (UPJO).Methods:The clinical data of 13 children with UPJO diagnosed by robot-assisted single-port plus-one laparoscopic pyeloplasty in Fujian Provincial Hospital from September 2021 to August 2022 were retrospectively analyzed. The mean age of the children was 60.0 (1.3, 108.0) months. The lesions of 10 patients were on the left, and 3 were on the right. The clinical manifestations were abdominal pain in 3 cases, urinary tract infection in 2 cases, and no symptoms in 10 cases. Preoperative isotope renogram showed affected renal function (28.32±1.82)%, and bilateral renal function difference > 10% in 7 cases. Mechanical obstruction existed in 5 cases. Preoperative ultrasound showed the affected side's renal cortex thickness of (1.98 ± 0.23) cm. During the operation, a single-port multi-channel trocar was placed in the umbilicus with another single port in the epigastrium, and a robotic system was placed to explore the subperitoneal dilated renal pelvis. The renal pelvis was suspended and pulled through the abdominal wall. The visual field was exposed, and the dilated renal pelvis was incised. The dilated renal pelvis was cut, a ureteral stent was placed, and the ureteropelvic duct was anastomosed.Results:The operation of 13 cases was successfully completed, without conversion to open surgery. The operation time was 180.0(165.0, 190.2)min. The intraoperative blood loss was < 5 ml. The postoperative hospital stay was 7.0(7.0, 7.0)d, and hospitalization costs were 56.3(52.1, 56.5)thousand yuan. The ureteral stent was removed 2 months after the operation, and no obvious complications such as urinary tract infection or low back pain occurred. The median postoperative follow-up was 12 months, ranged from 6 to 18 months. Urinary color ultrasound showed that the renal cortex was (4.95±0.57) cm, which was thicker than before. Isotope renogram showed that the renal function was (38.02±1.76)%, which was higher than before. Mechanical obstruction was transformed into incomplete obstruction.Conclusions:Da Vinci robot-assisted single-port plus-one laparoscopic pyeloplasty is precise and could achieve good surgical results on the basis of the effective restoration of lesion kidney function.

MethodStatistics on the meridians for properties and tastes, efficacy, medicinal parts, family and genus, and chemical components of TCM from latex-containing plants were carried out. A total of 53 TCM from latex-containing plants included in the 2020 edition of the Chinese Pharmacopoeia were screened by mining the Chinese Botanical Journal, Chinese Materia Medica, Dictionary of Traditional Chinese Medicines, and related literature. In addition, their meridians for properties and tastes, medicinal parts, chemical components, and TCM classifications were summarized and statistically analyzed by using Excel 2013 and ChiPlot 2023.3.31 software. ResultIt was found that latex-containing plants were mainly distributed in one kingdom, one phylum, two classes, and 20 families, and most of the TCM from latex-containing plants belonged to Dicotyledonaceae under Angiosperms. In terms of properties and tastes, plain>cold>warm>cool>hot and bitter>pungent>sweet>sour>salty. In terms of meridians, liver>lung>kidney>spleen=large intestine=stomach>heart>bladder=gallbladder=small intestines. In terms of medicinal parts, roots (root, rhizomes, tuberous root, and root bark)>resin>seed>whole herb (whole herb and above-ground part)>stem (stem and branch)>fruit>leaf>flower=skin. In terms of research on chemical components, they were mostly glycosides. In terms of TCM classification, they were mostly medicines for activating blood circulation and removing blood stasis. ConclusionThe TCM from latex-containing plants is mainly plain, with a uniform warm and cold distribution. The tastes are mainly bitter and pungent, and the major meridians are the liver and lung. The roots and resins are mainly used as medicines. The components mostly contain glycosides, alkaloids, and volatile oils, and most of them are medicines for activating blood circulation and removing blood stasis, as well as for removing heat and toxins. There is a certain degree of correlation among the growth habits, medicinal parts, chemical components, and the properties, tastes, and efficacy of the TCM from latex-containing plants. It may provide a reference for resource development and utilization of TCM from latex-containing plants.

ObjectiveTo make statistics on the biological characteristics, medicinal parts, chemical components, and other aspects of thorny medicinal plants and systematically analyze the correlations between their natures, tastes, and meridian tropism, so as to provide a theoretical basis for the clinical application and resource development of these plants. MethodThe Chinese Pharmacopoeia (2020 edition) and the processing standards of various provinces and cities and other related documents were reviewed, on the basis of which 46 species of thorny medicinal plants were selected. The natures, tastes, meridian tropism, medicinal parts, chemical components, pharmacological activities, and geographical distribution of these plants were summarized and analyzed in Excel 2013 and SPSS Statistics 26.0. ResultThe 46 species of thorny medicinal plants belonged to 25 families, 1 class, 1 phylum of 1 kingdom. In terms of the location of thorns, the frequency of these medicinal plants followed the trend of leaf thorns>peel thorns>branch thorns>fruit thorns. In terms of the nature, taste, and meridian tropism, the frequency of these plants was in the orders of warm>plain>cold>cool>hot, bitter>sweet>pungent>sour>salty, and liver>lung>spleen=large intestine>heart>kidney, respectively. In terms of the medicinal parts, the frequency followed the trend of roots and rhizomes>fruits>whole plants>flowers>leaves. The thorny medicinal plants were mainly distributed in north and southwest China. The thorny medicinal plants mainly contained flavonoids, alkaloids, and saponins and had the effects of clearing heat and detoxifying, resolving stasis and eliminating carbuncle, moving Qi and relieving pain, and alleviating edema and expelling pus. Moreover, 24 of them had anti-tumor activity. ConclusionMost of the thorny medicinal plants belong to Compositae, Leguminosae, and Rosaceae, have leaf thorns, a warm nature, a bitter taste, tropism to the liver meridian, and roots as the medicinal part. These plants are mainly distributed in north China, with the effects of clearing heat and detoxifying, resolving stasis and eliminating carbuncle. In summary, the thorn location, distribution, and medicinal parts of thorny medicinal plants are correlated with the natures, tastes, and meridian tropism. The findings provide clues for the development and utilization of these plants.
