This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material， covering aspects such as nomenclature， origin， geographical distribution， harvesting and processing methods， quality assessment， therapeutic effects and indications， by consulting ancient herbal texts， medical compendia， and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty， with Zhuli being the standard name used throughout history， alongside aliases like Zhuzhi， Zhuyou and Huoquan. Historically， the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis（Danzhu）， although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou（present-day Chengdu and surrounding areas in Sichuan） and the Wuling region（between present-day Hunan， Guangdong， Guangxi and Jiangxi provinces）， while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally， Bambusae Succus was harvested from bamboo that had grown for exactly one year， today， it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation， whereas modern industrial production employs dry distillation， reflux extraction， and percolation. In terms of quality evaluation， ancient texts considered a sweet taste to be superior， while today， clarity and transparency are prioritized. Historically， Bambusae Succus was characterized as sweet and cold nature， targeting the lung and stomach meridians， with uses evolving from clearing heat and resolving phlegm to nourishing Yin， moistening dryness， and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet， bitter， and cold in nature， affecting the heart， liver， and lung meridians， with functions including clearing heat， resolving phlegm， and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion， lung heat with phlegm congestion， convulsions， epilepsy， excessive phlegm in febrile diseases， high fever with thirst， irritability during pregnancy， and tetanus， with more clearly defined applications. Based on the results of the research， it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus， the one-year-old Phyllostachys nigra var. Henonis， which has been highly praised throughout history， should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore， in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste， and reasonable modern quality control standards should be established.

AIM:This study aims to investigate the mechanisms underlying skeletal muscle mitochondrial damage associated with decline in exercise function during high-altitude de-adaptation,using a mouse model.METHODS:Twen-ty-four healthy male C57BL/6J mice were randomly assigned to two groups:a high-altitude de-adaptation group and a plain control group.The model group was exposed to a low-pressure,low-oxygen chamber simulating an altitude of 7 000 meters for two weeks,followed by eight days of rearing in a plain environment.The control group was maintained in a plain envi-ronment for the same duration.Grip strength and pole-climbing tests were conducted on the 1st,3rd,and 5th days post-re-turn to assess muscle strength and motor coordination.Treadmill exercises were performed on the 4th and 8th days to eval-uate exercise endurance.After the treadmill exercise on the 8th day,serum,liver,and skeletal muscle tissues were col-lected.Levels of lactic acid(LA),glucose(GLU),creatine kinase(CK),lactate dehydrogenase(LDH),alanine trans-aminase(ALT),and aspartate aminotransferase(AST)in serum,as well as glycogen levels in the liver and muscle,were analyzed.Additionally,the expression of proteins related to mitochondrial biogenesis,fission,fusion,and oxidative phos-phorylation in muscle tissues was assessed using Western blot.RESULTS:(1)The model group exhibited significant re-ductions in grip strength,increased pole-climbing T-turn and total times,and decreased total time and distance in the ex-haustion running test.(2)Serum levels of LA,CK,LDH,ALT,and AST were elevated,while GLU levels decreased,and glycogen levels in both the liver and muscle were reduced in the model group following the treadmill exercise.(3)Ab-normal indicators in the model group did not return to normal by the end of the de-adaptation period.(4)Western blot analysis revealed decreased expression of mitochondrial oxidative phosphorylation proteins(ATP6V1A and Mt-CO2)and mitochondrial biogenesis proteins(PGC-1α and FGF21),increased levels of mitochondrial fusion proteins(OPA1 and MFN1),and no significant changes in fission protein expression(FIS1 and DRP1)in muscle tissue from the model group.CONCLUSION:Exercise capacity in mice during the high-altitude de-adaptation period significantly declined,particu-larly in terms of muscle strength,motor coordination,and endurance.This decline is closely associated with abnormal pro-tein expression related to skeletal muscle mitochondrial energy metabolism and production.

Objective To explore the effects of vitamin D on anxiety and depression behavior and the mechanism of hippocampal inflammation in obese rats.Methods Male Wistar rats were randomly divided into 4 groups(n=12):control group(group C),obesity group(group F),low-dose vitamin D group(L-VD group),and high-dose vitamin D group(H-VD group).Group C was fed a standard diet,and the other three groups were fed a high-fat diet.After successful establishment of the rat obesity model,L-VD group and H-VD group were intraperitoneally injected with 10 μg·kg-1·d-1 and 20 μg·kg-1·d-1 vitamin D,respective-ly,and groups C and F were injected with the same volume of normal saline;relevant indexes were detected af-ter continued feeding for 6 weeks.The sucrose preference test and open field test were used to study the be-havior of rats in each group.The histopathological changes of hippocampal tissue were observed by HE stai-ning.The expression levels of TNF-α and NF-κB protein in hippocampal tissue were detected by Western blot.Results After 6 weeks of intervention,compared with group C,the serum 25(OH)D concentration,sugar-wa-ter preference rate,total distance of open field movement,number of entries into the central area,and duration of stay in the central area were significantly decreased in group F rats.The expression levels of TNF-α and NF-κB proteins in hippocampal tissues were significantly increased(P<0.05).Compared with group F,serum 25(OH)D concentration and sugar-water preference rate were significantly increased in L-VD and H-VD groups.Anxiety and depression-like behaviors in the open field were markedly improved.TNF-α and NF-κB protein levels were significantly decreased(P<0.05).Statistically significant differences were observed in all aforementioned indicators between the groups(P<0.05).HE staining revealed looser arrangement of hipp-ocampal neurons,with extensive neuronal degeneration in group F.In contrast,L-VD and H-VD groups exhib-ited tighter and more regular neuronal arrangements,with only mild edema and cytoplasmic vacuolation in some cells.No significant neuronal degeneration was observed in the H-VD group.Conclusion Reduced vita-min D levels in obese rats exacerbate anxiety-depression-like behaviors,potentially through activation of hipp-ocampal inflammatory factors.

Objective To investigate the anatomical characteristics of the right top pulmonary vein(RTPV),a rare variant pulmonary vein displayed on chest CT,and its clinical significance in thoracoscopic right lung surgery.Methods The clinical data from 27 patients who underwent thoracoscopic right lung surgery were collected.Of these,24 patients were diagnosed with RTPV by preoperative chest CT.The anatomical characteristics were analyzed in combination with three-dimensional reconstruction.Three cases were diagnosed with RTPV based on preoperative chest CT after abnormal veins behind the intermediate bronchus were identified during surgery.Results Of the 27 patients of RTPV,22 cases drained blood from the posterior segment of the right upper lobe(S2),4 cases drained blood from both the S2 and S6a,and 1 case drained blood from both the S2 and S1a.After crossing behind the intermediate bronchus,13 cases returned blood to the lower pulmonary vein,5 cases returned blood to V6,7 cases returned blood to the left atrium,and 2 cases returned blood to the root of the upper pulmonary vein.The vascular diameter of the RTPV was(5.1±1.7)mm.All 27 patients successfully completed thoracoscopic surgery without massive hemorrhage caused by accidental injury to the PTRV.The intraoperative anatomy corresponded to the preoperative chest CT and three-dimensional reconstruction.The intraoperative bleeding volume was(44.6±43.7)mL,and there was no massive hemorrhage caused by accidental injury to the RTPV.Nine patients underwent right lower lobectomy,and four patients had the RTPV preserved,with no postoperative hemoptysis.Five patients underwent RTPV transection,of which two experienced transient hemoptysis following surgery with no serious complications.Conclusion Chest thin-section CT can be applied to diagnose RTPV.Preoperative identification via CT is crucial to avoid massive hemorrhage resulting from accidental injury during thoracoscopic surgery of the right lung.RTPV can be preserved as appropriate in patients undergoing right lower lobectomy.
