ABSTRACT
Objective: To estimate the consumption level of four drugs in Beijing using wastewater-based epidemiology (WBE). Methods: The primary sludge from one large wastewater treatment plants (WWTPs) was collected in Beijing from July 2020 to February 2021. The concentrations of codeine, methadone, ketamine and morphine in the sludge were detected through solid-phase extraction-liquid chromatography-tandem mass spectrometry. The consumption, prevalence and number of users of four drugs were estimated by using the WBE approach. Results: Among 416 sludge samples, codeine had the highest detection rate (82.93%, n=345) with a concentration [M(Q1, Q3)] of 0.40 (0.22-0.8) ng·g-1, and morphine had the lowest detection rate (28.37%,n=118) with a concentration [M(Q1, Q3)] of 0.13 (0.09, 0.17) ng·g-1. There was no significant difference in the consumption of the four drugs on working days and weekends (all P values>0.05). Drug consumption was significantly higher in winter than that in summer and autumn (all P values<0.05). The consumption [M(Q1, Q3)] of codeine, methadone, ketamine and morphine in winter was 24.9 (15.58, 38.6), 9.39 (4.57, 26.72), 9.84 (5.18, 19.45) and 5.67 (3.57, 13.77) μg·inhabitant-1·day-1, respectively. For these drugs, there was an upward trend in the average drug consumption during summer, autumn and winter (the Z values of the trend test were 3.23, 3.16, 2.19, and 3.32, respectively and all Pvalues<0.05). The prevalence [M(Q1, Q3)] of codeine, methadone, ketamine and morphine were 0.0056% (0.0034%, 0.0092%), 0.0148% (0.009%, 0.0267%)、0.0333% (0.0210%, 0.0710%) and 0.0072% (0.0038%, 0.0117%), respectively. The estimated number of drug users [M(Q1, Q3)] was 918 (549, 1 511), 2 429 (1 578, 4 383), 5 451 (3 444, 11 642) and 1 173 (626, 1 925). Conclusion: Codeine, methadone, ketamine and morphine have been detected in the sludge of WWTPs in Beijing, and the consumption level of these drugs varies in different seasons.

AIM: To compare the effect of different courses of budesonide nasal spray on the postoperative efficacy of endoscopic dacryocystorhinostomy.METHOD: Prospective study. A total of 90 patients(90 eyes)with chronic dacryocystitis who underwent endoscopic dacryocystorhinostomy in our hospital from January 2019 to April 2022 were selected, and they were randomly divided into three groups. In group A, 30 patients(30 eyes)continued to use budesonide nasal spray for 2mo after surgery; in group B, 30 patients(30 eyes)continued to use budesonide nasal spray for 3mo after surgery; in group C, 30 patients(30 eyes)continued to use budesonide nasal spray for 4mo after surgery. Follow-up for 6mo after surgery, Lund-Kenndey score, surgical efficacy and complications of the three groups were compared.RESULT: At 3, 4 and 6mo after surgery, the Lund-Kenndey score of group C was lower than that of group A(P<0.05), and there was no statistical difference between group C and group B(P>0.05). Following up to 6mo, the surgical efficacy of group C was better than that of group A, and the incidence of complications was lower than that of group A(P<0.05); There was no statistically significant difference in efficacy and complications between group C and group B(P>0.05).CONCLUSION: Budesonide combined with endoscopic dacryocystorhinostomy has acceptable efficacy in the treatment of chronic dacryocystitis. After 3mo of treatment, inflammation can be well controlled, which can reduce the occurrence of postoperative complications and improve the effective rate of surgery. However, increasing the treatment course cannot further improve the effective rate of surgery.
ABSTRACT
ObjectiveTo determine the epidemiological characteristics and risk factors of hypertension in residents in Songjiang District of Shanghai， and provide evidence for prevention and control of hypertension. MethodsLocal residents aged between 20 and 74 years were recruited from four towns in Songjiang District from 2016 to 2017 by using a multistage sampling strategy. Questionnaire surveys were conducted， and then physical examination， blood pressure measurement， glucose test and lipid test were performed. The data was analyzed by SPSS 16.0 software. Chi-square test was used to compare the differences in the prevalence of hypertension in residents， stratified by demographics and health conditions. Risk factors were determined by multivariate logistic regression. ResultsAmong 35 759 residents with a median age of 58 years and the proportion of male being 40.67%， crude prevalence of hypertension was 54.24% （19 395/35 759） and standardized prevalence was 31.69%. In the hypertensive patients， proportion of hypertension awareness was 61.09%， with 63.67% in male and 59.10% in female. Proportion of receiving treatment was 49.00%， with 50.91% in male and 47.51% in female. Furthermore， in the hypertensive patients with treatment， proportion of effectively controlling hypertension was 40.50%， with 44.46% in male and 37.21% in female. Multivariate logistic regression showed that male （OR=1.272）， senior age （40‒59 years old： OR=4.353， 60‒74 years old： OR=9.802）， overweight （OR=1.823）， obesity （OR=3.070）， central obesity （OR=1.380）， diabetes （OR=1.923）， dyslipidemia （OR=1.452）， and drinking （OR=1.338） were risk factors associated with hypertension. ConclusionPrevalence of hypertension is high， while the proportions of receiving treatment and effective control remain low in residents in Songjiang District. It warrants strengthening prevention and control of hypertension in targeted and young residents.
ABSTRACT

ABSTRACT
Objective@#To assess the interobserver variations in delineating the planning target volume (PTV) and organs at risk (OAR) using different contouring methods during intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC), aiming to provide references for the quality control of multi-center clinical trials.@*Methods@#The PTV and OAR of CT image of 1 NPC patient manually delineated by 10 physicians from 8 different radiation centers were defined as the " manual contour group" , and the OAR auto-contoured using the ABAS software and modified by the physicians were defined as the " auto+ manual contour group" . The maximum/minimum ratio (MMR) of the PTV and OAR volumes, and the coefficient of variation (CV) for different delineated contours were comparatively evaluated.@*Results@#Large variation was observed in the PTV and OAR volumes in the manual contour group. The MMR and CV of the PTV were 1.72-3.41 and 0.16-0.39, with the most significant variation in the PTVnd (MMR=3.41 and CV=0.39 for the PTVnd-L). The MMR and CV of the manually contoured OAR were 1.30-7.89 and 0.07-0.67. The MMR of the temporal lobe, spinal cord, temporomandibular joint, optic nerve and pituitary gland exceeded 2.0. Compared with the manual contour group, the average contouring time in the auto+ manual group was shortened by 68% and the interobserver variation of the OAR volume was reduced with an MMR of 1.04-2.44 and CV of 0.01-0.37.@*Conclusions@#Large variation may occur in the PTV and OAR contours during IMRT plans for NPC delineated by different clinicians from multiple medical centers. Auto-contouring+ manually modification can reduce the interobserver variation of OAR delineation, whereas the variation in the delineation of small organs remains above 1.5 times. The consistency of the PTV and OAR delineation and the possible impact upon clinical outcomes should be reviewed and evaluated in multi-center clinical trials.

ABSTRACT
Objective:To investigate the effects of acupuncture-rehabilitation therapy on homocysteine (Hcy) and cognitive function in patients with cognitive impairment after ischemic stroke. Methods:From July, 2017 to June, 2018, 88 patients with cognitive impairment after ischemic stroke were randomly divided into group A (n = 29, cluster needling), group B (n = 30, cognitive training) and group C (n = 29, acupuncture-rehabilitation). Their serum Hcy content was measured and they were assessed with Montreal Cognitive Assessment (MoCA) before and 30 days after treatment. Results:The serum Hcy content was the least in group C after treatment (F = 6.570, P < 0.01), with the most score of MoCA (F = 31.526, P < 0.001). Conclusion:Acupuncture-rehabilitation therapy is more effective than simple cluster needling or cognitive training for patients with cognitive impairment after ischemic stroke.

Surgical complications including temporary subcutaneous exudates were cleared up by puncture and aspiration in 5 cases, subcutaneous hematoma duo to drainage removal in 1 case, of which an emergency evacuation was performed and the implant was still with instant incision closure and then smooth recovery eventually. No significant abnormal fluctuation of laboratory examination was reported, moreover no artifact interference was found on postoperative CT scan or MR image. The subjective feelings and external sensory effects are satisfactory in patients. No emerging dysfunction of central nervous system or other organs was found, and no long-term complication was appeared. Conclusion It is feasible and safe to apply PEEK implant to cranioplasty without additional operative difficulty. This kind of material is an ideal alternative for repairing skull defect to patients with good financial condition and specific demands for postoperative status especially.
ABSTRACT
OBJECTIVE:To investigate the inhibitory effect of Baixuan xiatare tablet on the model mouse with allergic contact dermatitis (ACD). METHODS:60 BALB/c mice were equally randomized into normal control (isometric solvent) group,model (isometric solvent)group,ebastine(positive control,0.003 g/kg)group and the groups of high,middle and low doses of Baixuan xiatare tablet(2.0,1.0 and 0.5 g/kg). The mice were given drugs,ig,once daily for 14 consecutive days. 0.5% 2,4-dinitrofluoro-benzene(DNFB)acetone olive oil solution was applied,for sensitization,on the prepared mouse’s skins one and two days before administration,and 0.2% DNFB acetone olive oil solution on their left ears 16 days thereafter to establish mouse models of ACD. At 48 h after successful establishment of the models,the thickness of the mouse’s left ear margin was measured and the difference value and swelling degree were calculated;flow cytometer was used to determine the levels of T lymphocyte subsets CD4+ and CD8+ in mouse blood and calculate the ratio of CD4+ to CD8+;the levels of interleukin 4(IL-4)and IL-6 in mouse serum were de-termined. RESULTS:Compared with normal control group,those in the model group had higher difference value of ear margin and swelling degree,lower level of CD4+ in blood and ratio of CD4+ to CD8+,and higher content of IL-6 in serum. There was statisti-cally difference (P<0.01). Compared with model group,those in the groups of high,middle and low doses of Baixuan xiatare tablet had lower degree of left ear swelling and higher level of CD4+ in blood;those in the groups of high and middle doses thereof had lower difference value of left ear margin and level of IL-6 in serum;and those in the group of high dose thereof had higher lev-el of CD8+ in blood. There was statistically significance(P<0.01 or P<0.05). CONCLUSIONS:Baixuan xiatare tablet has inhibi-tory effect to some degree on the mouse model with ACD by a mechanism which may be related to the balance of subsets CD4+and CD8+in blood and the reduction of IL-6 in serum.
ABSTRACT
Background: The relationship between Helicobacter pylori (Hp) infection and the risk of esophageal squamous cell carcinoma is unclear. Aim: The purpose was to investigate the effects of CagA+ Hp on esophageal squamous carcinoma Ec 109 cells in vitro and explore the molecular mechanisms underlying these effects. Materials and Methods: Ec 109 cells were treated with CagA+ Hp fi ltrate at a concentration of 1.0 mg/mL or 50 μg/mL in vitro, proliferation and apoptosis of Ec 109 cells were assayed, the secretion of IL-8 was measured by ELISA, and the levels of Src homology-2 domain-containing phosphatase (SHP-2) mRNAs was assayed by RT-PCR.. Furthermore, after pretreatment of Ec109 cells with the specifi c p38 mitogen-activated protein kinase (MAPK) inhibitor SB203580, the p38 pathway was detected. Results: CagA+ Hp fi ltrate enhanced both the proliferation and apoptosis of Ec 109 cells. In addition, cytokine IL-8 release was signifi cantly increased, and the expression of SHP-2 mRNA declined sharply in the CagA+ Hp group. Furthermore, after pretreatment of Ec109 cells with the specifi c p38 MAPK inhibitor SB203580, Ec109 cells proliferation and IL-8 secretion were inhibited. Conclusions: Our results suggest that CagA+ Hp fi ltrates could induce proliferation and the secretion of IL-8 by Ec109 cells in vitro. IL-8 secretion was induced through the activation of the p38 MAPK signal pathway.

ABSTRACT
Many laboratories have been attempting to integrate Chinese medicine (CM) with the research of stem cells in order to explore this promising frontier. Studies on the combination of CM and bone marrow-derived mesenchymal stem cells (BMSCs) have found that some effective components from CM could activate endogenous stem cells and induce stem cells to differentiate into neural-like cells in vitro and promote angiogenesis. This review summarized the latest research findings of BMSCs and their application combined with CM in the treatment of cerebral ischemia.

Objective To probe the value of multi-slice spiral CT angiography (MSCTA) in decreasing surgical trauma of the cranial base meningioma. Methods Thirty-two patients with cranial base meningioma were examined preoperatively with MSCTA to observe the shape and the relationship with the adjacent vessels and the skull base. Three-dimensional images were reconstructed to imitate the approach of operation and compared with surgical findings. Meanwhile, 22 patients withnot MSCTA were selected randomly as control group. The amount of blood transfusion and the occurrence rate of complications were compared between the two groups. Results MSCTA depiceted clear three dimensional images of the meningioma and the relationship with the adjacent vessels and the skull base, corresponded very well to the surgery. By imitating the operation, all patients were designed the incision size of bone appropriately, the vessels of peritumoral were kept off effectively and the risk of the embedded vascular were assessed accurately. The conventional surgical approach and method were changed in 9 patients, 4 formulated the planning of the sub-total resection and radiotherapy preoperatively. Compared with control group, the amount of blood transfusion reduced significantly (P<0.05) and postoperative complications decreased. Conclusion MSCTA can imitate the surgical operations in multi-angle and supply the vital information for choosing the proper surgical approach, thereby reducing surgical trauma and postoperative complications.
