Nuclear radiation exposure events and tumor radiotherapy are highly susceptible to a range of psychological, physiological and other health problems, which can seriously affect patients' quality of life. It has been shown that 87.5 % of tumor patients are exposed to varying degrees of radiation injury during radiotherapy. The treatment of radiation injury (RI) in modern medicine is limited to drug therapy, cell therapy, etc. Among them, the most chemical drugs cause many adverse reactions including fatigue, nausea, vomiting, etc., and there are very few drugs dedicated to the treatment of RI. Traditional Chinese medicine (TCM) is a rich natural medicinal resource, which has a wide range of pharmacological activities, multiple targets of action and minimal toxic side effects. Many studies have demonstrated that TCM and its compound preparations have enormous potential in the treatment of radiation induced comprehensive diseases. However, TCM is limited in clinical application due to its slow onset of action, complex active ingredients, and low bioavailability. Therefore, the article reviews the application, molecular mechanisms, and new dosage forms of TCM in the prevention and treatment of RI. On this basis, we will focus on discussing the development advantages and application prospects of the combination of traditional Chinese and Western medicine to achieve highly efficient treatment of RI. This review aims to provide scientific and effective drug delivery strategies and basic theoretical support for the clinical effective treatment of RI with TCM, and further promote the innovative development of TCM.

Objective To investigate the effects and mechanism of Yuyin Qianyang Tongluo Formula on cognitive function in Alzheimer's disease mice.Methods Transgenic negative mice were designated as the normal group,while APP/PS1 double transgenic mice were randomly divided into six groups(ni=6 per group):model group,low-dose Yuyin Qianyang Tongluo Formula group,medium-dose group,high-dose group,and positive drug group.The Yuyin Qianyang Tongluo Formula low-,medium-,high-dose groups correspondingly received intragastric administration of 0.75,1.5,and 3 g·kg-1·d-1,respectively.The positive drug group received 2 mg·kg-1·d-1 donepezil hydrochloride tablets,while the model and normal groups received equal volumes of saline.All groups were treated once daily for 8 weeks.Behavioral tests were conducted using the Morris water maze and Y-maze.Hippocampal β-amyloid(Aβ)1-42 level was measured by enzyme-linked immunosorbent assay(ELISA).Hippocampal CA1 and CA3 neurons were observed hematoxylin-eosin(HE)staining,and Nissl bodies were examined Nissl staining.Protein expression levels of Aβ transporter low-density lipoprotein receptor-related protein 1(LRP-1)and endoplasmic reticulum stress marker glucose-regulated protein 78(GRP78)were detected by Western Blot analysis.Results(1)Compared with the normal group,the model group showed significantly prolonged escape latency(P＜0.000 1),reduced platform crossings,decreased movement distance and time around the platform of Morris water maze test(P＜0.05 or P＜0.01),significantly lower spontaneous alternation percentage in Y-maze test(P＜0.05),and significantly elevated hippocampal Aβ1-42 level(P＜0.000 1).Compared with the model group,all Yuyin Qianyang Tongluo Formula dose groups and the positive drug group exhibited significantly shortened escape latency of Morris water maze test(P＜0.000 1).The high-dose Yuyin Qianyang Tongluo Formula group and positive drug group showed significantly increased platform crossings,movement distance and time around the platform of Morris water maze test(P＜0.05),significantly higher spontaneous alternation percentage in Y-maze test(P＜0.05).All Yuyin Qianyang Tongluo Formula dose groups and the positive drug group showed significantly reduced hippocampal Aβ1-42 level(P＜0.000 1).(2)Compared with the normal group,the model group exhibited disordered and deformed hippocampal neurons and Nissl bodies.Compared with the model group,all Yuyin Qianyang Tongluo Formula groups and positive drug group showed improved neuronal and Nissl body organization,with the improvement degree positively correlated with dosage.(3)Compared with the normal group,the model group showed decreased LRP1 level and increased GRP78 level,but there were no statistically significant differences(P＞0.05).Compared with the model group,the high-dose Yuyin Qianyang Tongluo Formula group and positive drug group showed increased LRP1 level,while all Yuyin Qianyang Tongluo Formula dose groups and positive drug group exhibited decreased GRP78 level,but there were no statistically significant differences(P＞0.05).Conclusion Yuyin Qianyang Tongluo Formula significantly improves cognitive and memory function in model mice in a dose-dependent manner,potentially through reducing Aβ aggregation in the brain via endoplasmic reticulum stress pathway.

Objective To investigate the efficacy of biportal endoscopic transforaminal lumbar interbody fusion(BE-LIF)in the treatment of lumbar spondylolisthesis complicated with osteoporosis.Methods From June 2021 to June 2022,36 cases of lumbar spondylolisthesis complicated with osteoporosis were treated with BE-LIF,including 9 males and 27 females,aged(65.94±6.83)years(range:51～76 years).All were single segment,and the responsible segment was L3/4 in 4 cases,L4/5 in 26 cases,and L5/S1 in 6 cases.Imagingexamination showed 1 and 2 degree of spondylolisthesis in 28 and 8 cases,and degenerative and ischemic spondylolisthesis in 24 and 12 cases respectively.Preoperative average bone mineral density T value of the lumbar spine was(-3.19±0.82)SD,and T value of the femur(-2.26±0.86)SD.Oswestry disability index(ODI)was used to evaluate lumbar spine function;visual analogue scale(VAS)to evaluate low back pain and leg pain.ODI,VAS of low back and leg pain were recorded respectively before the operation,at discharge and at the last follow-up.MacNab criteria were used to evaluate the surgical efficacy at the last follow-up.The anterior and posterior disc height,segmental lordotic angle and percentage of slip were measured on the lateral lumbar X-ray films before and after the operation.All patients received standard anti-osteoporosis treatment after surgery.Results All patients completed the opera-tion in one stage.The average operation time was(160.97±35.01)min(range:105～245 min),and the average intraoperative blood loss was(72.50±47.53)ml(range:20～150 mL).The mean follow-up time was(15.17±6.53)months(range:6～26 months).There were statistically significant differences in both VAS score of back and leg and ODI score at discharge and last follow-up when compared with those before the surgery(F=107.48,103.66,55.52,P<0.001).Macnab criteria of the last follow-up showed excellent in 21 cases,good in 12 cases,fair in 3 cases,and the excellent and good rate was 91.7%.Radiographic results showed that the height of the ante-rior and posterior disc height,segmental lordotic angle and percentage of slip were all improved immediately after surgery and at the last follow-up when compared with those before operation,but the anterior and posterior disc height,segmental lordotic angle at the last follow-up were decreased comparing with those immediate after the operation;the difference was statistically significant(P<0.001).The fusion rate at the last follow-up was 91.7%(33/36).The complication rate was 13.8%(5/36),including 1 case of intraoperative endplate injury,1 case of nerve root cuff tear,1 case of delayed postoperative wound infection,and 2 cases of posterior cage migration.Conclusion BE-LIF for the treatment of lumbar spondylolisthesis complicated with osteoporosis can achieve better immediate reduction effect,good clinical outcomes and high fusion rate in short-term follow-up,but the anterior and posterior disc height,segmental lordotic angle are partially lost at the last follow-up.There are still complications,and beginners should be cautious when performing the operation.Postoperative standardized anti-osteoporosis treatment is still an important measure to ensure the curative effect of surgery.

Objective: To determine the effect of polygona-polysaccharose (PP) on learning and memory ability in rats with Alzheimer’s disease (AD). Methods: Forty ifve Sprague-Dawley rats were assigned into 3 groups. Rats in the sham-operated group were injected with normal saline. Rats in the Aβ group were injected with Aβ1-42. Rats in the PP group were injected with 16% PP solution for 45 days consecutively. hTe Morris water maze was used to investigate the ability of learning and memory in the rats. hTe effect of Aβ and PP on the hippocampus cells was observed by HE and Congo red staining of methanol. Results: Rats in the sham-operated group had no obvious morphological change; and morphology of rats in the PP group was basicaly normal. The layer of pyramidal cells in the Aβ group was decreased. hTe cells appeared sparse and irregular and became smaller. Karyopyknosis and vacuolardegeneration cells were also found. More positive staining materials aggradated in the Aβ group compared with the PP group by Congo red staining (P<0.05). Conclusion: Aβ infusion into the hippocampus results in the impairment of the neuronal degeneration in the rats, which shows similar characterizations of AD. PP can reduce the deposition of Aβ in the hippocampus.

OBJECTIVE: To explore the effects of laminaria japonica polysaccharides(LJP) and tea polyphenols (TP) on nasopharyngeal carcinoma(NPC) cells HONE1 and CNE2, and further to explore the underlying mechanism of antitumor activity of LJP on NPC cell in vivo. METHOD: To identify the logarithmic growth phase of NPC cells HONE1 and CNE2 through cell growth curve and doubling time by means of MTT, then inhibition of the cells proliferation were detected with LJP and TP separately and combined. With LJP treatment, cell apoptosis of HONE1 was examined by double staining assay. A tumor model,established by subcutaneously inoculation of NPC cell HONE1 into nude mice,was used to evaluate the inhibitory effect of LJP in vivo. RESULT: Both LJP and TP had inhibition effect on two groups of cell proliferation, and LJP and TP combined effect of inhibition were higher than the two separate on two sets of experimental cell proliferation, whose effect was concentration-dependent. LJP could induce apoptosis of HONE1. With the increasing concentration of LJP, apoptosis rate increased. The apoptosis rate was(49.51 +/- 1. 89) % (P<0. 01) when treated with 320 mg/L LJP. The inhibition rate was between 50% to 60% at 72 h after treatment with 320 mg/L LJP. Compared to control group, the growth of xenografts in nude mice was significantly suppressed after administration of LJP at a dose-dependent manner. The inhibition rates were 33. 7%(P<0. 05)and 47. 0%(P<0. 01) when treated with 25.0 mg/kg and 50. O mg/kg respectively. Whereas the inhibition rate of 12.5 mg/kg group was only 16. 4%(P>0. 05). CONCLUSION LJP and TP can inhibit the proliferation of NPC cells HONE1 and CNE2 respectively,and combined use has a significant effect. LJP can inhibit the growth of NPC probably by inducing apoptosis of NPC cells in vitro and in vivo.

Sixteen dogs were allocated to 4 groups in equal number and were fed with Rad ix Rhod od end ri Mollis 0.170, 0.345 and 1.420 g/kg for three months respectively, with one group as control. The results showed that Rad ix Rhod od end ri Mollis can cause focal necrosis, edema, ballooning degeneration and fatty degeneration of liver cells. It can also increase the permeability of glomerulus, and cause edema and even ballooning degeneration of renal tubular epithelial cells. Biochemical analysis showed that GPT and BUN apparently increased. Urine analysis showed that qualitative examination of protein, epithelial cells, white and red blood cells were all positive. It is considered that long-term administration of Rad ix Rhod od end ri Mollis can cause functional and structural damage of liver and kidney, and timely suspension of the drug and treatment may render the damage.
