Objective To investigate quantitatively the thermal sensation characteristics of the patients with facial palsy and the value of quantitative thermal test (QTT) in prognostication.Methods The QTT threshold of the fore ear and cheek of 30 patients with peripheral facial palsy was tested,their facial nerve conduction velocity was measured,and House-Brackmann facial nerve grading system was used to estimate facial nerve function at 2～3 weeks,a month,two months and half a year post onset.Results It was found that 12 out of 30 patients had abnor- mal QTT threshold value;the majority of them suffered from herpes virus and diabetes.In those with abnormal QTT, 8 were with diabetes mellitus (account for 66.7%),3 with partial shingles (account for 25%),and 1 with positive serum virus infection (account for 8.3%).Those with normal QTT were significantly different from those with abnor- mal QTT,with regard to the House-Brackmann rating scores after 2 and 6 months post onset (P

Ochratoxin A (OTA) is a toxic secondary metabolite mainly produced by Aspergillus and Penicillium species, existing in a variety of foodstuffs and Chinese medicines. OTA is difficult to be detected in practice because of the characteristics such as trace amounts, toxicity, existing in complex matrices. In the numerous detection technologies, colloidal gold chromatographic techniques are highly sensitive, specific, cost-effective and user-friendly, and are being used increasingly for OTA screening. Recently, with the development of aptamer technology and its application in chromatographic technique, a newly colloidal gold aptamer chromatographic technique has been developed. This review elaborates the structures and principles of both traditional and newly colloidal gold chromatographic techniques, focuses on newly colloidal gold aptamer chromatographic technique, summarizes and compares their use in rapid detection of OTA. Finally, in order to provide a reference for better research of related work, the development trends of this novel technique are prospected.

OBJECTIVETo compare the clinical efficacy in the treatment of allergic rhinitis (AR) of lung qi deficiency and cold syndrome between Jin's three-needle therapy and western medication.

METHODSSixty-six patients were randomized into an acupuncture group and a western medication group, 33 cases in each one. In the acupuncture group, acupuncture was applied at three-nose points [Yingxiang (LI 20), Shangyingxiang (EX-HN 8) and Yintang (GV 29); Cuanzhu (BL 2) was added for frontal headache] and three-back points [Dazhu (BL 11), Fengmen (BL 12) and Feishu (BL 13)], once every day. Ten treatments made one session. Two sessions of treatment were required. In the western medication group, desloratadine oral suspension was prescribed, 5 mg each time, once a day, for 20 days. The scores of the symptoms and physical signs in AR patients as well as the clinical efficacy were observed between the two groups.

RESULTSThe total effective rate was 93.9% (31/33) in the acupuncture group, which was better than 72.7% (24/33) in the western medication group (P < 0.05). After treatment, the scores of AR symptoms and physical signs as well as the total score were all reduced compared with those before treatment in the two groups (all P < 0.01). The score of every item in the acupuncture group was lower than that in the western medication group after treatment (score of symptoms: 4.70 +/- 2.07 vs 6.55 +/- 2. 69, score of physical signs: 0.85 +/- 0.67 vs 1.45 +/- +0.62, total score: 5.36 +/- 2.70 vs 8.00 +/- 2.91, all P < 0.01).

CONCLUSIONJin's three-needle therapy achieves superior efficacy on AR of lung-qi deficiency and cold syndrome, which is better than desloratadine oral suspension.

A method was developed for the determination of ochratoxin A (OTA) in human urine by HPLC-FLD after molecularly imprinted polymer solid phase extraction (MIP-SPE) column. After the pH being adjusted to 2.5 with 0.1 mol x L(-1) HC1, sample was cleaned up with MIP-SPE column for ochratoxin A, the analyte was analyzed by high performance liquid chromatography coupled with fluorescence detection (HPLC-FLD), and finally all the positive results were confirmed by LC-MS/MS. Recoveries from urine samples spiked with OTA at levels ranging from 2 to 20 ng x mL(-1) were 90.6%-101.9%, and RSDs were 0.1%-1.6%. Sixty-five volunteers living in Beijing took part in the study, of which 5 were found containing OTA in their urine and the highest value was 0.091 ng x mL(-1). The MIP-SPE column was firstly applied to purify and concentrate OTA in human urine, this method is simple, rapid and reliable and can be used to determine the contents of OTA in human urine.

OBJECTIVETo survey the incidence of acute febrile reaction in elderly patients receiving intravenous zoledronic acid for osteoporosis and identify the related factors.

METHODSThirty-eight elderly patients with osteoporosis were hospitalized and treated with intravenous infusion of 5 mg zoledronic acid in 2010. The incidence of acute fever reaction was observed in these patients , and the time of fever onset, duration, average maximum temperature, and antipyretic drug used were recorded. The patients with and without acute febrile reaction were compared for age, duration of osteoporosis, sex ratio, use of parathyroid hormone before zoledronic acid treatment, β-fragment of collagen breakdown, calcitonin, osteocalcin, serum calcium, and use of anti-osteoporosis drugs before the treatment.

RESULTSAcute fever reaction occurred in 12 (31.6%) of the patients. Two of the patients had fever on the day of zoledronic acid treatment, and the other patients developed fever after the first day of treatment, with a mean duration of 1 day and a maximum temperature of (38.5∓0.84) degrees celsius;. The fever was treated with a mean of 3.55∓1.21 pseudoephedrine tablets. The patients with fever showed significantly higher parathyroid hormone levels before treatment than those without fever (P<0.05); osteocalcin, calcitonin, β-fragment of collagen breakdown, or serum calcium showed no significant difference between the two groups.

CONCLUSIONAcute febrile reaction, often moderate and transient, is common in elderly patients receiving intravenous zoledronic acid for osteoporosis, and its occurrence is possibly associated with parathyroid hormone levels before the treatment.

OBJECTIVETo examine UVB-induced responses in normal human keratinocytes (HaCaT) and epidermoid carcinoma cells (A431) at the cellular and molecular level, and investigated the protective effect of salidroside.

METHODSCells irradiated by UVB at various dosage and their viability was assessed by MTT assays, cell cycle was analysed by flow cytometry. The expression of NF-κB, BCL-2, and CDK6 after 50 J/m(2) UVB irradiation were detected by RT-PCR and western blotting.

RESULTSOur results confirmed greater tolerance of A341 cells to UVB-induced damage such as cell viability and cell cycle arrest, which was accompanied by differential expression changes in NF-κB, BCL-2, and CDK6. UVB exposure resulted in HaCaT cells undergoing G(1)-S phase arrest. When treated with salidroside, HaCaT survival was significantly enhanced following exposure to UVB, suggesting great therapeutic potential for this compound.

CONCLUSIONTaken together, our study suggests that A431 respond differently to UVB than normal HaCaT cells, and supports a role for NF-κB, CDK6, and BCL-2 in UVB-induced cell G(1)-S phase arrest. Furthermore, salidroside can effectively protect HaCaT from UVB irradiation.

Objective:To investigate the MRI features of perirenal space involvement in patients with acute pancreatitis (AP) and its correlation with disease severity.Methods:A total of 128 AP patients admitted to Bishan District People′s Hospital of Chongqing from June 2018 to June 2020 were selected as study subjects. All patients were diagnosed by ultrasound guided percutaneous biopsyand the pathological diagnosis results were taken as the gold standard. The accuracy, sensitivity and specificity of MRI diagnosis were calculated to analyze the correlation between MRI features of perirenal space involvement and MRI severity index (MRSI).Results:Among the 128 patients, 96 patients with perirenal space involvement in AP confirmed by ultrasound guided percutaneous biopsyand the pathological diagnosis results, accounted for 75.00%. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value diagnosed by MRI were 95.83%, 93.75%, 95.31%, 97.87% and 88.24% respectively. The involvement rate of perirenal space in AP was 75.00%(96/128), and that in mild, moderate and severe AP was 52.38%(22/42), 93.62%(44/47) and 7/7, respectively. Forty-two mild patients presented abnormal signals in the pancreas, or focal and diffuse pancreatic enlargement, thickening, and abnormal streak signalabnormalities in perirenal space, perirenal MRI showed grade 1 and 2. Forty-seven patients with moderate disease showed patchy signal abnormalities in the perirenal space, and perirenal MRI showed grade 3. Seven severe patients found perirenal interstitial effusion which was patchy. There was a good correlation between MRI features grade of perirenal space involvement and MRSI ( r = 0.721, P<0.001). The consistent rate of MRI features score of the right perirenal space was 91.14%, the consistent rate of MRI features score of the left perirenal space was 95.38%, and the consistent rate of MRSI observation on both was 90.21%. Conclusions:MRI can effectively and accurately diagnose perirenal space involvement in AP patients, MRI features and involvement rate can accurately reflect the severity of AP, which has a positive effect on clinical diagnosis and treatment of patients with perirenal space involvement in AP.

Objective:To investigate the value of diffusion tensor imaging (DTI) in evaluating the cognitive function of patients with leukoaraiosis (LA).Methods:A prospective study was chosen. Sixty patients with LA admitted to our hospital from July 2019 to May 2021 were selected. All patients accepted brain MRI. According to Fazekas visual grading standards, these 60 LA patients were divided into mild LA group, moderate LA group, and severe LA group ( n=20). Mini-mental state examination (MMSE) was used to evaluate the cognitive function of these patients. Diffusion tensor imaging was used to analyze the fractional anisotropy (FA) values of 6 regions of interest, namely the frontal lobe, temporal lobe, occipital lobe, parietal lobe, anterior horn of lateral ventricle, and corpus callosum. The differences of general data, cognitive function and FA values among the 3 groups were compared. The cognitive functions were assessed based on FA values (FA scores), and compared with those evaluated by MMSE (clinical scores). Results:(1) Age and homocysteine (Hcy) level of patients in mild, moderate and severe LA groups were increased successively, with statistical differences ( P<0.05). As compared with that in the mild and moderate LA groups, the educational level of patients in the severe LA group was significantly lower ( P<0.05). (2) Memory scores of patients in mild LA group, moderate LA group and severe LA group decreased successively, with statistical differences ( P<0.05). As compared with mild LA group and moderate LA group, MMSE total scores and recall scores in severe LA group were statistically decreased ( P<0.05). (3) FA values of parietal lobe and corpus callosum were successively decreased in mild, moderate and severe LA groups, with significant differences ( P<0.05). As compared with those in the mild and moderate LA groups, the FA values of frontal lobe, temporal lobe, occipital lobe and anterior horn of lateral ventricle in severe LA group were significant decreased, ( P<0.05). (4) There were no significant differences in FA scores and clinical scores of cognitive function scores in mild LA group ( P>0.05), except for attention and counting scores. There were no significant differences in FA scores and clinical scores of cognitive function scores in moderate LA group ( P>0.05), except for language function scores and tMMSE otal scores. Except for scores of location orientation, attention and counting, FA scores and clinical scores of all cognitive function scores in the severe LA group were significantly different ( P<0.05). Conclusions:The LA severity is related to the patient's age, Hcy level, education level, and cognitive function. In patients with mild LA, the cognitive function can be assessed according to FA values in addition to attention and counting ability; in patients with moderate LA, cognitive function can be assessed according to FA values in addition to language function; the cognitive function of patients with severe LA cannot be assessed according to FA values.
