OBJECTIVE To provide ideas for clinical diagnosis， treatment and pharmaceutical care of rhino-orbito-cerebral mucormycosis （ROCM）. METHODS The diagnosis and treatment of 1 case of ROCM in which clinical pharmacists participated were analyzed. Combined with treatment guidelines， the actual situation of drug accessibility and economy， clinical pharmacists recommend amphotericin B colloidal dispersion in combination with posaconazole to treat fungal infections. The clinical efficacy， liver and kidney function and electrolytes were monitored. To increase the local concentration of amphotericin B deoxycholate （AmB-D）， clinical pharmacists assisted physicians in determining the dosage and formulation of AmB-D for intrathecal injection， intranasal and eye drops based on the results of blood and cerebrospinal fluid examinations. In response to the situation that the plasma trough concentration of posaconazole had not reached the target， clinical pharmacists recommended that Posaconazole oral suspension was replaced with Posaconazole enteric-coated tablets， and provided the patient with therapeutic drug monitoring （TDM）， individualized medication guidance， and long-term follow-up after discharge. RESULTS The clinician adopted the advice of the clinical pharmacists. After treatment， the patient was discharged from the hospital with medicine after her condition improved. CONCLUSIONS Clinical pharmacists develop individualized treatment protocols for ROCM patients by adjusting dose and dosage forms， providing medication monitoring and TDM to ensure the safety of drug use for patients.

Objective To investigate the diagnostic value of cervical vagus nerve cross-sectional area(CAS)for Parkinson's disease(PD).Methods Thirty patients with PD admitted to the People's Hospital of Zhengzhou University from October 2019 to October 2022 were selected as PD group,25 patients with multiple system atrophy(MSA)admitted to the People's Hospital of Zhengzhou University during the same period were selected as the MSA group,and 30 healthy individuals who underwent physical examination in the People's Hospital of Zhengzhou University during the same period were selected as healthy control group.Cervical vagus CAS of subjects in the three groups were measured by high-resolution ultrasound,and the difference of CAS of cervical vagus nerve was compared among the three groups.The degree of impairment of autonomic nervous function of subjects in the three groups was evaluated by PD autonomic symptom scale(SCOPA-AUT).The diagnostic value of cervical vagus nerve CAS for PD was analyzed by receiver operating characteristic(ROC)curve.Results The CAS of the right cervical vagus nerve of subjects was significantly larger than that of the left in the healthy control group and PD group(P＜0.05);there was no significant difference in CAS of bilateral cervical vagus nerve of subjects in the MSA group(P＞0.05).The CAS and average CAS of bilateral cervical vagus nerve of subjects in the PD group and MSA group were significantly lower than those in the healthy control group(P＜0.01).The CAS of the right vagus nerve of subjects in the MSA group was significantly lower than that in the PD group(P＜0.05);there was no significant difference in CAS and the average CAS of the left vagus nerve between the MSA group and the PD group(P＞0.05).The total score of SCOPA-AUT and gastrointestinal(GI),cardiovascular(CV),urinary(UR)and sexual(SX)scores of subjects in the PD group and MSA group were significantly higher than those in the healthy control group(P＜0.01).The total score of SCOPA-AUT and UR,SX scores of subjects in the MSA group were significantly higher than those in the PD group(P＜0.05).There was no significant difference in temperature(TH)and pupil(PU)of subjects among the three groups(P＞0.05).Pearson correlation analysis showed that the CAS of cervical vagus nerve of PD patients was not correlated with the total score of SCOPA-AUT and the UR,TH,PU,SX scores(r=-0.143,0.281,0.297,0.265,0.312;P＞0.05).The CAS of cervical vagus nerve of PD patients was negatively correlated with GI and CV scores(r=-0.683,-0.373;P＜0.05).ROC curve analysis showed that the area under the curve of cervical vagus nerve for diagnosing PD was 0.870(95％confidence interval:0.773-0.966,P＜0.05);the critical value was 3.064 mm2,the sensitivity was 96％,and the specificity was 67％.The area under the curve of CAS of cervical vagus nerve in differential diagnosis of PD,MSA was 0.680(95％confidence interval:0.537-0.823,P＜0.05).The sensitivity and specificity for the diagnosis of MSA were 68％and 70％when the CAS of the cervical vagus nerve＜2.709 mm2.Conclusion The CAS of cervical vagal nerve has high clinical diagnostic value for PD,and it provides a new way to improve the diagnosis rate of PD.

Objective:To analyze the differences in whole blood selenium (Se), zinc (Zn), copper (Cu), magnesium (Mg), calcium (Ca), and iron (Fe) levels of rural older adults among areas with different soil selenium levels, and explore the main factors associated with the six nutrient elements status, so as to provide a basis for further evaluating the health risks of people in areas with different soil selenium levels.Methods:Four administrative villages were randomly selected from the Se-deficient (soil Se content < 0.175 mg/kg), Se-sufficient (soil Se content 0.175 - < 0.400 mg/kg), Se-rich (soil Se content 0.400 - < 3.000 mg/kg) and Se-excessive (soil Se content ≥3.000 mg/kg) areas, respectively, in Enshi Tujia and Miao Autonomous Prefecture (Enshi Prefecture) of Hubei Province in 2017 - 2018. And 100 elderly people aged 60 years or older (half male and half female) were randomly selected as the survey subjects in each servey site. The basic information such as general demography and lifestyle was collected through face-to-face questionnaires. Physical examination was performed and fasting venous blood was collected in the morning. The contents of blood Se, Zn, Cu, Mg, Ca, and Fe were determined by inductively coupled plasma mass spectrometry. The main factors associated with the six nutrient elements status were analyzed.Results:A total of 416 subjects were included, including 208 males and 208 females, whose average age was (72.43 ± 5.25) years, and body mass index (BMI) was (22.67 ± 3.49) kg/m 2. There were significant differences of blood Se, Zn, Cu, Mg, Ca and Fe levels between the areas with different Se levels ( Z/F = 288.30, 3.24, 14.81, 29.14, 131.28, 3.37, P < 0.05). Compared with Se-deficient and Se-sufficient areas, blood Se level was higher in Se-rich and Se-excessive areas and blood Zn level was lower in Se-excessive area ( P < 0.05); compared with Se-sufficient area, blood Cu level was lower in Se-deficient, Se-rich and Se-excessive areas, but blood Mg and Ca levels were higher ( P < 0.05), and the blood Fe level was lower in Se-excessive area ( P < 0.05). There were significant differences in the deficiency rates of Se, Zn, Cu, Mg, Ca and Fe among the elderly in different Se level areas (χ 2 = 140.83, 15.39, 31.90, 17.49, 157.60, 30.33, P < 0.01). There were significant differences in blood Zn, Cu, Ca and Fe levels between two gender groups ( P < 0.05); the blood Zn and Fe levels of the smokers were higher than those of the non-smokers, and the blood Cu level was lower than that of the non-smokers ( P < 0.05); the blood Zn and Fe levels of the drinkers were higher than those of the non-drinkers ( P < 0.05). Conclusions:The levels of six nutrient elements in the whole blood of the elderly in areas with different soil Se levels are different. To assess the health risks of the population in areas with different soil Se levels, it is necessary to consider the levels of multiple nutrient elements at the same time.

Objective: To compare the color stability of Biodentine and mineral trioxide aggregate (MTA) within the blood environment in vitro and to further investigate the underlying reasons for such color instability. Methods : We first generated Biodentine and MTA discs with a diameter of 5 mm and a height of 3 mm. 24 discs of each material were randomly divided into two groups: the deionized water group and the defibrinated sheep blood group. Discs of each group were immersed for 1 day or 7 days before assessments. First, all discs were photographed to directly compare the discoloration of Biodentine and MTA. The color degree of the two materials was tested by a spectrophotometer. Then, the high-resolution morphological characteristics were observed by scanning electron microscopy. Finally, the chemical contents of each element in the material were measured by energy-dispersive spectroscopy. Results : Compared to immediately after stripping, a change in the brightness of discs after immersion in defibrinated sheep blood for 1 day was observed only in MTA. On the 7th day after being immersed in blood, the colors of both the Biodentine and MTA discs darkened and turned deep red, but the darkness of the MTA discs increased significantly. The color change of MTA immersed in blood was measured on a spectrophotometer with a greater 7-day ∆E (21.257 ± 0.955) than the Biodentine 7-day ∆E (5.833 ± 0.501) (t=24.781, P < 0.001). MTA exhibits more discoloration as the immersion time goes on. A significant difference was noted between the 1-day ∆E(6.233 ± 0.888) and the 7-day ∆E(t=19.956, P < 0.001) of MTA immersed in blood. However, there was no statistically significant difference between the 1-day ∆E (6.790 ± 0.831) and the 7-day ∆E(t=1.707, P=0.163) of Biodentine immersed in blood. It was observed by scanning electron microscopy that after 7 days of immersion in the defibrinated sheep ablood, the surface porosity of MTA was larger than that of Biodentine, and the crystal edge of MTA became rounded and blunt. The analysis by energy-dispersive X-ray spectroscopy showed that the oxygen content decreased and the bismuth content increased in MTA after immersion in defibrinated sheep blood for 7 days. Zirconium was not detected in Biodentine due to its low radiodensity, but the contents of other elements were stable in Biodentine after immersion in defibrinated sheep blood for 7 days. Conclusion The color stability of Biodentine within the blood environment is better than that of MTA in vitro, which is mainly related to the low surface porosity and stable composition of the anti-radiation agent of Biodentine.

Objective: To evaluate the intervention effects of response to heatwave in communities of four cities, China. Methods: Baseline survey on heatwave and climate change related knowledge, attitude and practice (KAP) was conducted in the pilot communities in Harbin, Nanjing, Shenzhen and Chongqing, using face-to-face questionnaire interview in November, 2011 to November, 2013. Finally, 1 604 residents were interviewed. Intervention measures were implemented in summers of 2013 and 2014, including delivering early warning information of heatwave health risk and launching health education and promotion. The second survey was conducted in same communities using the same questionnaire and sampling method as baseline survey in November, 2014, and 1 640 residents were interviewed. The Chi-square test was used to compare the demographic characteristics and KAP of community residents between before and after intervention, and the factors that affected the intervention effect were selected by logistic multiple stepwise regression model. Results: The age of the residents interviewed before and after intervention was (46.4 ± 15.5) years and (45.0 ± 15.9) years, respectively. Overall, the residents' awareness rates of heatwave before and after intervention were 70.5% (1 131/1 604) and 82.9% (1 359/1 640) (χ²=69.40, P<0.001). The rate of residents who had wished to receive early warning information increased 6.3% (χ²=41.11, P<0.001), which reached 94.6% (1 551/1 604) after intervention from 88.3% (1 416/1 604) in baseline survey. Both heatwave health risk early warning and health education had big impacts to residents. There were 92.7% (1 105 residents) among the 1 192 residents who had received the early warning information arrange work and rest time according to the early warning information and 93.0% (1 231 residents) among the 1 323 residents who knew about health education activities being conducted in community thought that the community health education activities had made active role in protecting health from heatwaves. After a series of intervention, male had a effect on attitude about hot wave than female in Nanjing and Chongqing, OR (95%CI) were 1.48(1.02-2.16) and 1.45 (1.18-2.05) , respectively; compared with subjects below primary school education, people with college degree or above had higer KAP in all cities (ORs range from 1.18 to 2.05), P<0.05; regular physical exercise (ORs range from 1.39 to 2.70) also had profound impacts on KAP in all cities (P<0.05). Conclusion s Early warning and health education were effective measures to enhance residents' response capacity to climate change.

BACKGROUND: Integrin α5β1 has been shown to be related to acetabular cartilage degeneration due to developmental dysplasia of the hip.OBJECTIVE: To investigate the expression of integrin α5β1 in differently degenerated cartilage tissues of the knee after knee osteoarthritis.METHODS: Seventy-five degenerated articular cartilage specimens at the weight-bearing surface of femoral lateral and medial condyles were removed from patients with knee osteoarthritis who underwent total knee replacement, and were then allotted to four groups based on Mankin's grading system: normal (n=6), mild degeneration (n=24), moderate degeneration (n=26) and severe degeneration (n=19) groups. The expression of integrin α5β1 in each group was detected using real-time PCR, immunohistochemistry and western blot assay.RESULTS AND CONCLUSION: The detected results were consistent in the three kinds of assays, and the expression level of integrin α5β1 was ranked as follows: severe degeneration group > moderate degeneration group > mild degeneration group > normal group (P < 0.05). To conclude, differential expression levels of integrin α5β1 are found in different degenerative degrees of articular cartilage in knee osteoarthritis. Furthermore, the expression level of integrin α5β1 is increased with the degenerative severity.

OBJECTIVETo compare the difference in clinical efficacy on bronchial asthma at chronic persistent stage between acupuncture for warming yang and benefiting qi and seretide.

METHODSOne hundred and eighty patients of bronchial asthma at chronic persistent stage were randomized into an acupuncture group and a western medication group, 90 cases in each one. In the acupuncture group, acupuncture for warming yang and benefiting qi was applied at Dazhui (GV 14), Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1), Jianshi (PC 5), Zhigou (TE 6), Taixi (KI 3) and Zusanli (ST 36), once every two days. In the western medication group, inhalation therapy with seretide was applied, 1 to 2 inhalations each time, twice a day. The treatment for 20 days was as one session in the two groups, at the intervals of 2 days after each session. Four sessions of treatment were required. The immune function indices were observed before and after treatment in the patients of two groups, named immunoglobulin IgG, IgM and IgE; peripheral T lymphocytes (CD3+), helper T lymphocytes (CD4+), inhibitory T lymphocytes (CD8+) and the ratio of CD4+ and CD8+; as well as the pulmonary ventilation function indices, named maximum pulmonary expiratory flow (PEF), forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). The clinical efficacy was compared between the two groups.

RESULTSThe total effective rate was 93.3% (84/90) in the acupuncture group, better than 88.9% (80/90) in the western medication group (P < 0.05). After treatment, the immune function indices and pulmonary ventilation function indices were apparently improved as compared with those before treatment in the two groups (all P < 0.05). The improvements in the acupuncture group were much more significant (all P < 0.05).

CONCLUSIONAcupuncture for warming yang and benefiting qi effectively controls the symptoms of bronchial asthma at chronic persistent stage and improves immune and pulmonary functions. The efficacy is better than that of seretide.

OBJECTIVETo explore the impacts on the life quality and the effect mechanism in the patients of allergic rhinitis (AR) treated with warm acupuncture in winter and summer.

METHODSTwo hundred and forty patients of AR were randomized into a summer and winter acupuncture group, a non-summer and winter acupuncture group and a western medication group, 80 cases in each one. In the two acupuncture groups, Dazhui (GV 14), Fengmen (BL 12), Feishu (BL 13), Pishu (BL 20) and Shenshu (BL 23) were selected. In the summer and winter acupuncture group, the warm acupuncture started at the first day of the three periods of hot season and the first day of the third nine-day period after the winter solstice. The treatment was given once every two days, continuously for 15 times. Totally, 30 treatments were required a year. In the non-summer and winter acupuncture group, the warm acupuncture was applied out of the three periods of the hot season and the third nine-day period after the winter solstice. The treatment was given once every two days and 30 treatments for a year. In the western medication group, cetirizine was taken orally, continuously for 30 days as one session. In the three groups, the treatment for 1 year was taken as one session. The second session started in the next year. Totally, 2 sessions were required. The score of rhinoconjunctivitis quality of life questionnaire (RQLQ) and the level of serum immunoglobulin E (IgE) were compared in the patients' of each group before treatment and in 1 and 2 sessions of treatment.

RESULTSAfter treatment, the scores of 7 domains, named activities, common complaints, practical problems, sleep, ocular symptoms, nasal symptoms and emotions were all improved as compared with those before treatment, in the patients of the three groups (all P < 0.05). After 2 sessions treatment, the results in the summer and winter acupuncture group were better than those in the other two groups (all P < 0.05), and the results in the non-summer and winter acupuncture group were better than those in the western medication group (all P < 0.05). After treatment, serum IgE level was lower averagely than that before treatment in the three groups (all P < 0.05). After 2 sessions treatment, the result in the summer and winter acupuncture group was lower than that in the other two groups (both P < 0.05), and the result in the non-summer and winter acupuncture group was lower than that in the western medication group (P < 0.05). After treatment, the total effective rate was 92.3% (72/78) in the summer and winter acupuncture group, better than 80.5% (62/77) in the non-summer and winter acupuncture group and 69.7% (53/76) in the western medication group (both P < 0.05).

CONCLUSIONThe warm acupuncture in both summer and winter achieves the definite efficacy on AR and the effect mechanism is relevant with reducing serum IgE level.

Arapidscreeningmethodforthedeterminationofcarbamatepesticides(CBPs)residuesin vegetables by measuring acetylcholinesterase ( AChE ) inhibition rate using electrospray ionization mass spectrometry ( ESI-MS ) has been established. After pretreatment by QuEChERS method, sample solution reacts with AChE using acetylthiocholine as substrate. AChE inhibition rate was calculated by determination of the conversion of substrate to product ( thiocholine) using ESI-MS. The temperature, time and concentration conditions of enzymatic reactions have been optimized. The relationship between the concentration of 10 kinds of common CBPs and AChE inhibition rate was researched. Matrix effects of real vegetables were studied. The limit of detection ( LOD) , which was measured by 3 times of enzyme inhibition rate of pesticide-free vegetable samples, was 0. 01-0. 05 mg/kg. The results showed that the method was better than the current national standard method of china for rapid screening of pesticide residues and fully meet the requirements of maximum residue limits( MRL) for pesticides in food of national food safety standard. False positive results were avoided effectively due to its good ability of resistance matrix interference. The reliability was proved by analyzing vegetables with liquid chromatography-tandem mass spectrometry. The method is simple, rapid, sensitive, reliable, and can be used for the rapid, high-throughput screening of CBPs in vegetables.

Objective To identify anal canal structures by dual plane transrectal ultrasound. Methods One anorectal specimen was observed by ultrasonography when needles were placed in different anal muscle layers respectively. Fifty patients with no anorectal or perianal diseases were examined by transrectal ultrasound to verify the sonographic features of anal canal, meanwhile the inner and outer sphincters and longitudinal combination muscle were measured. The ultrasound images of anal canal were compared with MR images. Fifty patients were divided into three groups according to the age: 25- 40 years old, 41 -55 years old,and ＞55 years old. Results The sonographic features of anal canal structures by transrectal ultrasound were identified. Anal canal sonographic images and MR images had consistency. The thickness of inner sphincter in each group was (0.19 ± 0.03)cm, (0.22 ± 0.02)cm, (0.24 ± 0.03)cm respectively,while outer sphincter (0.44 ± 0.03)cm, (0.49 ± 0.04)cm, (0.52 ± 0.04)cm, and longitudinal combination muscle (0.10±0.02)cm,(0.11 ± 0.02)cm,(0.11 ± 0.02)cm. Conclusions Transrectal ultrasound is a simple,efficient and non-invasive method to examine anal canal which can identify anal canal structures clearly.
