BACKGROUND:Cuscuta chinensis is a mature seed of Cuscutachinensis Lam., can warm kidney. Previous studies demonstrated that kidney compound composed of Cuscuta chinensis could apparently inhibit bone loss and improve bone density.
OBJECTIVE:To explore the influence of flavonoids from Cuscuta chinensis on bone mineral density of femur, 1,25(OH)2D3 levels of serum and kidney, the expression of smal intestine CaBp-D9K mRNA in model rats with ovariectomized osteoporosis.
METHODS:A total of 72 Sprague-Dawley female rats were equal y and randomly divided into six groups (n=12):sham surgery group, model group, vitamin D3 group and low-, moderate-and high-dose flavonoids groups. The sham surgery group only received sham operation and the other five groups were ovariectomized respectively. One week after ovariectomy, the rats were given flavonoids from low-, moderate-and high-dose Cuscuta chinensis and vitamin D3 (2 mg/kg) by intragastric administration for 3 consecutive months. Blood was obtained from the abdominal aorta. Serum was isolated. The kidney was obtained. Enzyme linked immunosorbent assay was used to determine 1,25(OH)2D3 contents of renal and serum. Rats were sacrificed at the end of experiment. The thighbone was taken out to determine bone mineral density. The second lumbar vertebra was taken out to measure the expression of lumbar vertebra and renal vitamin D receptor mRNA using real-time fluorescent reverse transcription-polymerase chain reaction. The smal intestine was taken out to measure the expression of smal intestine CaBp-D9K mRNA using real-time fluorescent reverse transcription-polymerase chain reaction.
RESULTS AND CONCLUSION:Compared with the sham operation group, bone mineral density of femur, and 1,25(OH)2D3 levels of serum and kidney and the expression of lumbar vertebra vitamin D receptor mRNA significantly decreased in model group, and the expression of smal intestine CaBp-D9K mRNA significantly decreased in model group. Compared with the model group, bone mineral density of femur, and 1,25(OH)2D3 levels of serum and kidney, and the expression of the second lumbar vertebra vitamin D receptor mRNA, and the expression of smal intestine CaBp-D9K mRNA were increased in moderate-and high-dose flavonoids groups and vitamin D3 group. Results indicated that flavonoids from Cuscuta chinensis could significantly raise bone mineral density of femur, and 1,25(OH)2D3 levels of serum and kidney and the expression of lumbar vertebra vitamin D receptor mRNA and the expression of smal intestine CaBp-D9K mRNA, accelerate intestinal calcium absorption and osteoblast activity, and reinforce quality of the bone.

BACKGROUND:Ischiogluteal bursitis has been recognized for a long time, but its treatment stil limits to local blocking injection and surgery methods that were developed 40 years ago. OBJECTIVE:To observe the efficacy of platelet-rich plasma on ischiogluteal bursitis. METHODS:Data of 15 patients with ischiogluteal bursitis were colected. Al the patients with ischiogluteal bursitis were treated with bilateral platelet-rich plasma (n=10) or local blocking injection (n=5). Patients’ outcomes were assessed by visual analogue scale, the Treatment Satisfaction Questionnaire for Medication (TSQM) Version II and recurrence rate. The folow-up time was from 6 to 14 months. RESULTS AND CONCLUSION: There was no statistical difference in visual analogue scale score between the platelet-rich plasma group and local blocking group (F=0.219,P=0.643), but the score of visual analogue scale in the platelet-rich plasma group was higher during short-term folow-up (within 1 week after treatment), but lower in the long-term folow-up. In the aspects of overal satisfaction score, clinical effectiveness and side effects, the platelet-rich plasma group was inferior to the local blocking group at short-term folow-up, especialy at 1 week after treatment; however, these scores became better in the platelet-rich plasma group than the local blocking group during the long-term folow-up period. In addition, no statistical difference in the convenience score was found between the two groups. At the last folow-up, the recurrence rate in the platelet-rich plasma group was lower than that in the local blocking group. Both the platelet-rich plasma and local blocking injection can significantly reduce the pain of patients with ischiogluteal bursitis. Local blocking injection has better short-term effectiveness. Platelet-rich plasma injection works moderately, but its effectiveness can last for longer time, and the recurrence rate is lower.

Objective:To analyze the effects of adenovirus-mediated interleukin-37 (IL-37) on the growth and radiosensitivity of human non-small cell lung cancer (NSCLC) cell line A549, and to explore the possibility of IL-37 as a new radiosensitizer.Methods:Human NSCLC cell line A549 was used as the research object. A549 cells were divided into three groups: normal A549 cells (control group), empty virus transfected A549 group [NC group, the multiple of infection (MOI) was 100], Ad-IL-37 group (A549 cells were transfected by adenovirus with IL-37, MOI was 100). The expression of IL-37 protein in three groups was detected by Western blot. The three groups were irradiated with 4 Gy irradiation dose at the same time. The methyl thiazolyl tetrazolium (MTT) method was used to detect the absorbance (A) values and observe the proliferation of A549 cells; flow cytometry was used to observe the phase changes of A549 cells in each group after irradiation; Western blot was used to detect the expressions of apoptosis-related proteins (bax, bcl-2, Caspase-3, and Survivin) in each group after irradiation.Results:The expression level of IL-37 in the control group was 0.17±0.04, NC group was 0.29±0.14, and Ad-IL-37 group was 1.17±0.23 (F = 24.263, P = 0.001); there was no statistical difference in A values among the three groups at 24 h after irradiation (F = 2.587, P = 0.160), while the differences of A values among the three groups at 48, 72, 96, 108 h after irradiation were statistically significant (F values were 21.662, 33.635, 33.663, and 31.909, P values were 0.005, 0.001, 0.001, and 0.001, respectively). There was no significant difference in the cell proliferation inhibition rate between NC group and Ad-IL-37 group at 24 h after irradiation (t = 1.620, P = 0.247), while the differences were statistically significant at 48, 72, 96, 108 h after irradiation (t values were 5.414, 7.233, 15.306, and 19.035, P values were 0.032, 0.019, 0.004, and 0.003, respectively). The combination of IL-37 and radiation could affect the cell cycle, the proportion of S-phase cells was (36.4±1.0)% in the control group, (31.3±0.6)% in the NC group, and (27.2±2.9)% in the Ad-IL-37 group (F = 12.96, P = 0.007), and the proportion of in G 2/M-phase cells was (20.5±0.8)% in the control group, (24.7±2.9)% in the NC group, and (41.4±4.1)% in the Ad-IL-37 group, (F = 27.92, P = 0.001). IL-37 could up-regulate the expressions of pro-apoptotic factors bax and Caspase-3 proteins in A549 cells after irradiation (F values were 10.31 and 14.51, P values were both 0.01), and down-regulate the expressions of apoptotic factors bcl-2 and Survivin proteins (F values were 8.95 and 5.52, P values were 0.02 and 0.04). Conclusion:IL-37 could inhibit the growth of human NSCLC cell line A549 and has potential radiosensitization effects, which may be caused by affecting the apoptosis of tumor cells.

Objective To summarize the safety and efficacy of Sunitinib in the treatment of metastatic renal clear cell carcinoma. Methods Fifteen patients with clear cell metastatic RCC were treated with Sunitinib,with 11 males and 4 females,aged from 26 to 74 years with median age of 55 years.Thirteen cases of 15 were T3 to T4 stage,and 8 cases underwent radical nephrectomy,while 5 other cases underwent renal biopsy with the pathological diagnosis of renal cancer.The other two cases (one man and one woman)with the solitary kidney renal cell carcinoma ( stage T1a) and renal insufficiency,were diagnosed as metastatic renal cell carcinoma by biopsy.Sunitinib monotherapy was administered by the regimen of 6 weeks per cycle with daily oral Sunitinib 4 weeks,followed by 2 weeks off ( from 1 - 10 cycles).Response was evaluated by RECIST.Renal tumor was 9.52 ± 3.3 cm in diameter at baseline,and the assessment of metastases included retroperitoneal lymph nodes (6 cases),mediastinal lymph nodes (3 cases),brain (2 cases),lung (6 cases),bone (2 cases) and liver (2 cases).Karnofsky score,tumor changes,adverse events and the survival of each patient was assessed and recorded. Results The follow-up duration was from 1.5 - 15months,with median follow-up of 6 months,and tumor response was evaluated by RECIST.Seven of 15 patients (46.7％) treated with Sunitinib achieved partial responses (PR),7 patients (46.7％) demonstrated stable disease (SD),and 1 patient (6.7％) developed progressive disease (PD) during the follow-up.Objective Response Rate (ORR) was 46.7％,PR + SD was 93.3％,6 months PFS was 93.3％,and median PFS was 12 months,respectively.Renal tumor was 8.7 ± 4.0 cm in diameter after therapy.Two PR patients with the obvious effectiveness had experienced progressed hypertension,and one cases with hypertension that could be controlled below 140/90 mm Hg ( 1 mm Hg =0.133 kPa) by a single drug before treatment,showed increased blood pressure ( ＞ 160/105 mm Hg) following the second cycles treatment,who were administered increased dosage and combination therapy.The other case without history of hypertension,showed high blood pressure ( ＞ 150/100 mm Hg) in the third cycle,and could be controlled well by antihypertensive drugs.Fortunately,the tumor of these two cases reduced obviously by more than 50％. 1/2 adverse reactions of 12 cases:yellowing of the skin and yellow sweat ( 12 cases,80％ ),fatigue ( 12 cases,80％ ),4 cases of hypothyroidism (26.7％),bilirubin and triglyceride levels elevated in 7case (46.7％); Four cases showed 3/4 degree adverse events with the emergence of gastrointestinal bleeding in one case secondary to platelets reduction (6.7％).Three cases (20％) showed serious fatigue,nausea,vomiting and severe hand-foot skin reaction. Conclusions Sunitinib is recommended for the treatment of metastatic renal clear cell carcinoma with good efficacy and safety.

Disruption of the structure of regular sleep is a common cause of neurodegenerative diseases such as Alzheimer′s disease and Parkinson′s disease, and its pathogenesis may be related to the deposition of waste products in the central nervous system. The glymphatic pathway, which is essentially a periarterial cerebrospinal fluid inflow pathway and peripheral venous clearance pathway, is functionally dependent on interstitial bulk flow coupling supported by aquaporin-4 on the astrocyte end-foot, also known as the lymphoid glial system. The glymphatic pathway, which removes waste proteins from the brain, is active primarily during sleep, and sleep quality declines with age, while the glymphatic pathway system also deteriorates with age, suggesting a relationship between sleep disturbances and symptom progression in neurodegeneration, and glymphatic system as a link closely links the two. The interaction of sleep, aging, metabolic waste and glymphatic pathway reticulation provides new clues to the pathogenesis of central nervous system degenerative diseases, and the glymphatic pathway may constitute a new target on treatment. The recent research progress on the effects of sleep and sleep disorders on the circulation of the glymphatic system, and proposes the possibility of sleep intervention to slow down the impairment of the lymphoid system function or even restore the function of the lymphoid system and thus improve the disease development process were reviewed in this paper.

Nonalcoholic fatty liver disease （NAFLD） is an abnormal lipid metabolic disorder of the liver characterized by accumulation of a large amount of lipids in the liver， and it is currently the most common liver disease around the world. Mendelian randomization （MR） incorporates genomic data into traditional epidemiological study designs to infer the causal relationship between exposure factors and disease risk. In recent years， MR has been widely used in studies on inference of the etiology of NAFLD. This article systematically summarizes the advances in the application of MR in NAFLD research， so as to provide new ideas for understanding the nature of the disease and scientific interventions.

In 2022, the European Association for the Study of the Liver issued Clinical practice guidelines on sclerosing cholangitis. With reference to the 2017 edition of Role of endoscopy in primary sclerosing cholangitis: European Society of Gastrointestinal Endoscopy (ESGE) and European Association for the Study of the Liver (EASL) Clinical Guideline (2017) and in comparison to the corresponding contents in Guidelines on the diagnosis and management of primary sclerosing cholangitis (2021) issued by Chinese Society of Hepatology, Chinese Medical Association, in 2021, this article summarizes the updates in diagnosis, treatment, monitoring, and management of special populations and analyzes the basis for updated recommendations and their guiding significance in optimizing the clinical management of primary sclerosing cholangitis (PSC). The comparative analysis shows that the new version of the guidelines is similar to the Chinese guidelines in terms of diagnosis, treatment, and follow-up, and it is worth learning from the technical details such as the recommended dose of ursodeoxycholic acid and long-term follow-up plan. Since PSC is a chronic refractory disease, the drugs recommended by current guidelines cannot delay or reverse disease progression, and there is still a lack of consensus statements on immunotherapy and screening protocols for end-stage complications, which might be the directions for further research.

OBJECTIVE： To provide reference for strengthening clinical application of key monitoring drugs and promoting rational drug use in clinic. METHODS： Based on evidence-based medicine， taking key monitoring drugs Shuxuetong injection as example， clinical evidence of domestic and foreign clinical studies were collected. The included literatures were graded according to the quality of GRADE evidence and recommended strength system. Evidence-based medicine evidence for the indications of Shuxuetong injection were evaluated， and criterion for clinical use of Shuxuetong injection was formulated in Huaihua First People’s Hospital （our hospital）. RESULTS： The main content of criterion for clinical application of Shuxuetong injection formulated by our hospital was that there was A-level evidence support for acute ischemic cerebral infarction， but it was weakly recommended and only used for adjuvant therapy； there was B-level evidence support for anticoagulation （for preventing DVT）， diabetic peripheral nerve lesion， but it was weakly recommended； there was only C-level or D-level evidence support for other indications， it was strongly recommendation against use. CONCLUSIONS： Clinical pharmacists formulate the criterion for clinical application of Shuxuetong injection by evidence quality evaluation method， provide reference for clinical application management of key monitoring drug and play an important effect on rational drug use in clinic.

To evaluate whether the in vitro fertilization-embryo transfer (IVF-ET) procedures could increases the risks of adverse pregnancy outcomes (APOs) in offspring.
 Methods: A hospital-based prospective cohort design was conducted, which contained a control group of singleton pregnancies with indicators of subfertility who were still conceived naturally after using simple medical treatment (e.g. minimal medical intervention or ovulation induction), and an exposure group consisted of singleton pregnancies who had a history of infertility and IVF-ET treatment. All factors different between two groups in the univariate analysis were included in the multivariable logistic regression to evaluate the independent effect of IVF-ET procedures themselves on APOs.
 Results: After controlling for confounding factors by using multivariate logistic regression analysis, our results showed that pregnancies after IVF-ET experienced a higher risk of preterm birth (OR=1.28, 95% CI 1.05 to 1.56), low birth weight (OR=1.69, 95% CI 1.27 to 2.31), perinatal mortality (OR=5.33, 95% CI 2.44 to 11.81), and congenital malformations (OR=1.83, 95% CI 1.12 to 2.94).
 Conclusion: The IVF-ET operational factors may increase the risk of APOs.
