Objective To observe the clinical efficacy of comprehensive muscle-region therapy based on Chuang Medicine in treating cervical spondylosis of neck type.Method A hundred patients with cervical spondylosis of neck type were randomized into a treatment group and a control group, 50 cases in each group. The treatment group was intervened by the comprehensive muscle-region therapy based on Chuang medicine (muscle-region tuina, fire-needle acupuncture of Chuang medicine, and cupping), while the control group was by regular acupuncture treatment. The Visual Analogue Scale (VAS) score and symptoms and signs scores were observed before and after intervention, and the clinical efficacies were compared.Result The VAS scores respectively after 1 and 2 treatment courses were significantly different from that before intervention in the treatment group (P<0.05,P<0.01). The VAS score after 2 treatment courses was significantly different from that before intervention in the control group (P<0.05). After 2 treatment courses, the VAS score in the treatment group was significantly different from that in the control group (P<0.05). After treatment, the symptoms and signs scores (pain intensity, pain-affected area, number of tender points, limited motion, and general score) were significantly different from that before intervention in the treatment group (P<0.01, P<0.05). In the control group, the pain intensity, limited motion and general score after treatment were significantly different from that before intervention (P<0.05,P<0.01). After treatment, the symptoms and signs scores in the treatment group were significantly different from that in the control group (P<0.05,P<0.01). The total effective rate was 100.0% in the treatment group versus 84.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Comprehensive muscle- region therapy in Chuang medicine is an effective approach in treating cervical spondylosis of neck type.

Objective To assess the diagnostic capability of spiral CT for giant pure seminoma in intraabdominal undescended testis.Methods Spiral CT of 6 cases with pure seminoma of inabdominal testes as proved by surgery and pathology were analyzed.All patients were male,and the age ranged from 31 to 45 years old with the mean of 35.2 years old.Results All tumors were located along the path of testicular descent on CT images.The arterial-supply of tumors all came from the testicular artery ipsilaterally.The draining vein could be seen between the mass and inferior vena cava or left renal vein in 5 cases.Isolaterally spermatic cord was absent in the inguinal region.Isolateral kidney was shifted upward.CT scans typically demonstrated a unilateral,mixed solid and cystic mass,with areas of solid located at the lateral aspect and areas of necrosis at the medial aspect.Contrast-enhanced CT scan showed mild enhancement of solid areas and band-like septal enhancement in areas of necrosis.There is no evidence of calcification or fat within the mass.Conclusion Spiral CT proves to be a very useful preoperative imaging modality for the giant intraabdominal seminoma.

Objective To analyze the clinical, endoscopic and histopathological features of eosinophilic gastroenteritis ( EG) in children. Methods A retrospective study of 76 children with EG was performed to analyze clinical symptoms, laboratory and imaging results, endoscopic and pathological features, status of Helicobacter pylori ( H. pylori) infection, treatment and outcomes. Results The main clinical symptoms were abdominal pain in 55. 3%(42/76) cases, vomiting in 39. 5% (30/76) cases and hematochezia in 38. 2% cases( 29/76) . The hemoglobin level decreased significantly in 34 cases ( 44. 7%, 34/76). Peripheral blood eosinophil (EOS) count increased significantly in 9 cases (11. 8%,9/76) and EOS percentage increased significantly in 13 cases(17. 1%,13/76). Total serum IgE elevated in 32 cases ( 54. 2%, 32/59 ) . There were also 18 cases ( 36. 7%, 18/49 ) positive in serum allergen?specific immunoglobulin E ( sIgE) test and 25 cases ( 32. 9%,25/76) positive in fecal occult blood test. Among 51 cases of abdominal ultrasound examination, there were 7 cases of ascites, 4 cases of pelvis fluid and 3 cases of intestinal wall change. Endoscopic examination in 76 cases showed 63 cases ( 82. 9%) of mucosal hyperemia/edema,20 cases ( 26. 3%) of ulceration, 17 cases ( 22. 4%) of erosion, 11 cases ( 14. 5%) of nodularity or hyperplasia and 9 cases ( 11. 8%) of normal mucosa. The pathological examination showed mucosal inflammation with a large number of EOS infiltration(≥20 per HPF).There were 12 cases(15. 8%, 12/76) of H. pylori infection. Among the 76 cases, clinical symptoms improved significantly in 74 patients after treatment with dietary allergen avoidance, anti?allergy medications, antacids, montelukast and corticosteroid, and the total efficacy was 97. 4%. The efficacy of dietary allergen avoidance, anti?allergy medications, antacids and montelukast was 93. 8%( 61/65 ) . The efficacy of corticosteroid was 86. 7%(13/15). Conclusion The clinical manifestations and endoscopic characteristics of EG in children lack specificity. In terms of diagnosis, the elevated total serum IgE and the positive sIgE test may be taken as reference for the diagnosis of EG. The definite diagnosis is based on pathological examination ( EOS infiltration≥20 per HPF).While in terms of treatment, dietary allergen exclusion, anti?allergy medications, antacids and montelukast are highly effective, which can be taken as the first option. There is no need of corticosteroid as routine therapy.

Objective:To discover the epidemiological characteristics and clinical manifestations of Nontyphoidal Salmonella(NTS) infection in children suffering from diarrhea in Guangzhou, and to provide references for the prevention and treatment of salmonella infection. Methods:A total of 570 diarrhea children and 296 non-diarrhea controls were collected with stratified sampling from three districts of Guangzhou Women and Children′s Medical Center from January 2019 to December 2019. Through bacterial culture, corresponding colonies were selected and Salmonella diagnostic serum was applied for preliminary serum diagnosis, and then systemic biochemical method was adopted for diagnosis. A structured questionnaire was conducted to record the demographic information and clinical symptoms from each subject. Results:The detection rate of NTS was 6.67% (38/570 cases, 95% CI: 4.90%-9.02%) in children with diarrhea, and 1.01% (3/296 cases, 95% CI: 0.34%-2.93%) in children without diarrhea. There were statistically differences in NTS detection rate between children with diarrhea and the control ( χ2=13.805, P<0.05, OR=6.976, 95% CI: 2.135-22.796). There were no significant differences in NTS detection rate between male and female children with diarrhea ( χ2=0.395, P>0.05, OR=1.254, 95% CI: 0.619-2.541). The detection rate of NTS was 5.30% (22/416 cases, 95% CI: 3.52%-7.88%) in children younger than 2 years old, and was 10.40% (16/154 cases, 95% CI: 6.50%-15.21%) in children over 2 years old. There were statistically differences ( χ2=4.700, P<0.05, OR=2.076, 95% CI: 1.060-4.068) between the younger and the older groups.The detection rate of NTS was 5.40% (25/460 cases, 95% CI: 3.70%-7.89%) for children with diarrhea in outpatient department and 11.80% (13/110 cases, 95% CI: 7.04 %-19.18%) for children with diarrhea in inpatient department, with statistically significant differences ( χ2=5.813, P<0.05, OR=2.332, 95% CI: 1.152-4.721). The detection rate of NTS diarrhea in children was 4.60% (10/217 cases, 95% CI: 2.52%-8.28%) in spring, 8.50% (12/141 cases, 95% CI: 4.93%-14.29%) in summer, 9.60% (15/144 cases, 95% CI: 6.41%-16.48%) in autumn and 1.50% (1/168 cases, 95% CI: 0.11%-3.30%) in winter, respectively, with statistically differences among the four seasons( χ2=9.404, P<0.05). There were significant differences in most common clinical symptoms of fever, vomiting, abdominal pain, bloody stool and pasty stool between NTS positive and negative children(all P<0.05). Salmonella enteritis is the main type, and Salmonella typhimurium is the second type. Conclusions:NTS is one of the most important bacterial pathogens and leads to diarrhea in children in Guangzhou city, without differences in gender.Children over 2 years old are more likely to suffer from NTS infection.High incidence is in autumn.The most common clinical symptoms include fever, vomiting, abdominal pain, bloody stool and pasty stool. Salmonella enteritis is the main type, and Salmonella typhimurium is the second type.Laboratory tests can provide references for the diagnosis and treatment of NTS-related diarrhea.

Objective To establish cell strain expressing the genes of HIV vpr and mutant HIV vpr-FS, and to explore cell apoptosis ability by HIV Vpr and Vpr-FS. Methods The recombinant plasmids were constructed by cloning HIV vpr and HIV vpr-FS genes into the eukaryotic expression vector pcDNA3.1respectively. To determine the primary structures of HIV vpr and HIV vpr-FS, plasmids were cleaved by restriction enzymes. After the plasmids were transfected into HeLa cells by liposome, the HeLa cells were selected with G418 selective medium, mRNA expression of HIV vpr or HIV vpr-FS of transfected cells was detected by RT-PCR, and Vpr and Vpr-FS protein expression were detected by Western blot assay respectively. The DNA content and the percentage of apoptosis in HeLa HIV vpr cell, HeLa HIV vpr-FS cell and HeLa pcDNA3.1 cell were monitored by flow cytometry and the DNA fragmentation was analyzed by agarose gel electrophoresis. Results BamH Ⅰ and Hind Ⅲ cleavaged products of pcDNA3.1-vpr and pcDNA3.1-vpr-Fincluded 342 bp length fragments suggesting that the length of DNA sequence containing HIV vpr (HIV vpr-FS) within pcDNA3.1 was the same as theoretical length. The HeLa cells transfected by pcDNA3.1-vpr or pcDNA3, l-vpr-FS and selected with G418 could express HIV vpr or HIV vpr-FS by RT-PCR, and express HIV Vpr or HIV Vpr-FS protein by Western blot. The results of flow cytometry and DNA fragmentation showed that there was significant different in the number of apoptotic cells between HeLa HIV vpr cell and HeLa HIV vpr-FS cell, but the difference between HeLa HIV vpr-FS cell and control group was not obvious. Conclusion Recombinant plasmids pcDNA3.1-vpr and pcDNA3. 1-vpr-FS were constructed successfully, and the cell strain expressing HIV Vpr and HIV Vpr-FS proteins was established. The HIV Vpr could induce host cell apoptosis, while the mutant of Vpr did not or weakened this ability. This study provides foundation for further study on HIV vpr gene.

OBJECTIVE: To study the changes of vestibular function in patients with diabetes mellitus and its clinical significance. METHOD: Electronystagmography (ENG) was used to examine 76 patients with diabetes mellitus and 60 healthy adults subjects. After clinical detection of vestibular function including spontaneous nystagmus, positional test, head shaking nystagmus, neck torsion test, caloric test, and sensory organization tests which consist of gaze, saccade and smooth pursuit test, the results of these two groups were recorded for qualitative and quantitative statistical analysis. RESULT: The rate of vestibular dysfunction in patients with diabetes mellitus were 68.4%. and that of the controls were 8.3%. There was significant difference between these two groups (chi2 = 15.472, P < 0.01). CONCLUSION Vertigo or dizziness occurred in patients with diabetes mellitus might be related to vestibular dysfunction. ENG test could be used as one of the objective clinical examinations in patients with diabetes mellitus.

OBJECTIVE: To study the characteristic of hearing loss and the changes of the auditory brainstem response and distortion product otoacoustic emission in diabetics. METHOD: General information of 136 diabetics were investigated whether had the complication of capillary vessel and hearing loss with self-made questionnaire at random. 136 cases (272 ears) were tested with ABR and DPOAE. They were divided into A, B, C, D four groups according to the age of per ten years (30-70 years). Other 120 (240 ears) matched healthy adult were enrolled in the control group. The pure tone threshold (PTT), acoustic impedance, ABR and DPOAE results were compared between the four groups and the control group, and then made statistical analysis. RESULT: When comparing to the control group, the interpeak latency I-V and ABR response were no significant difference between patients at the stage of 30 years. Not only the threshold of wave V was elevated with aging in patients over 40 years, but the amplitude of the peak latencies of waves III and V were lessening, and the interpeak latency III-V and I-V were prolonged between patients at the stage of 60 years, which had significant difference compared with age-matched patients (P < 0.05). The inducing rate of DPOAE were 100% in the test and control group, but the amplitude of DPOAE declined ranged from 1 to 8 kHz in patients with early diabetes mellitus and were significantly reduced at 4 kHz, which had significant difference compared with age-matched patients (P < 0.05). CONCLUSION The majority of patients with diabetes mellitus had slight and moderate hearing loss gradually. The ABR and the threshold of ABR response were varied with the age and sex of patients, and whether had the complication of capillary vessel, but were not related to its type and disease course. The DPOAE can comprehend the cochlear disorder in patients with early diabetes mellitus.

Objective:To investigate the predictive value of cerebroplacental ratio (CPR) for adverse perinatal outcomes of induction of labor in prolonged pregnancy.Methods:This retrospective study recruited 315 singleton pregnant women who had induced labor due to prolonged pregnancy (≥41 gestational weeks) in the First Affiliated Hospital of Chongqing Medical University from January 1, 2019 to April 30, 2020. Based on the occurrence of adverse perinatal outcomes (emergency delivery due to persistent abnormal fetal heart rate monitoring, umbilical artery blood pH at birth <7.2, 5 min Apgar scores<7, transferring to neonatal intensive care unit after birth, chorioamnionitis and vaginal delivery converted to cesarean section), they were divided into two groups: case group ( n=76) and normal group ( n=239). Clinical features and umbilical artery blood flow, middle cerebral artery (MCA) flow and CPR measured in the last ultrasound scan before induction were compared between the two groups using student's t-test, Mann-Whitney U test and Chi-square test. Receiver operating characteristic (ROC) curve was used to analyze the predictive values of umbilical artery blood flow, MCA flow and CPR for the adverse perinatal outcomes. Multivariate logistic regression analysis was used to screen the meaningful predictors. Results:Compared with the normal group, the umbilical artery pulsatility index (PI) (0.9±0.1 vs 0.8±0.1, t=-5.458, P<0.001) and the percentage of abnormal CPR (<1.0) increased significantly [21.1%(16/76) vs 6.3%(15/239), χ2=14.190, P<0.001] in the case group, while the MCA-PI and CPR decreased significantly (1.1±0.2 vs 1.3±0.3, t=5.658, P<0.001; 1.2±0.3 vs 1.6±0.5, t=8.940, P<0.001). The areas under the ROC curves of umbilical artery PI, MCA-PI and CPR for predicting adverse perinatal outcomes were 0.71, 0.71 and 0.77, respectively. CPR had the highest sensitivity (0.74) compared with umbilical artery PI (0.68) and MCA-PI (0.71), but the specificity of them were similar (0.67, 0.66 and 0.66). Multivariate logistic regression analysis showed that only CPR was the independent risk factor for adverse perinatal outcomes ( OR=0.028, 95% CI: 0.010-0.080, P<0.001). Conclusions:As an indicator for early prediction of adverse perinatal outcomes of induction of labor in prolonged pregnancy, CPR was more sensitive but less specific.

Objective:To investigate the effects of rapamycin (RAPA) on the cognitive function of lupus mice by regulating Cysteine rich 61 (Cyr61) and autophagy.Methods:MRL/lpr lupus mice were randomly divided into lupus group and rapamycin + lupus group, wild-type C57BL/6 mice were randomly divided into normal control group and rapamycin group with six mice in each group, RAPA + lupus group and rapamycin group were intraperitoneally injected with RAPA (2.0 mg/kg). The lupus group and the normal control group were injected with equal amounts of dimethyl sulfoxide (DMSO). Morris water maze was used to observe the cognitive function of mice. Western blotting was used to detect the expression of Cyr61, Programmed cell death-1 (Beclin-1), Microtubule associated protein 1 light chain3B (LC3B). Hematoxylin-eosin (HE) staining was used to observe the pathological changes in the hippocampus. The changes of neurons and bodies in hippocampus were observed by Nissl staining. The localization and expression of Cyr61 and LC3B in hippocampus were detected by immunofluorescence staining. One-way analysis of variance (ANOVA) was used between groups, and LSD-T test was used for pairwise comparison.Results:Western blotting results showed thatthe protein expression of Cyr61 (0.99±0.15) was significantly increased ( P=0.011), and the protein expression of Beclin-1 (0.64±0.04) and LC3B(0.54±0.05) was significantly decreased in lupus group ( P=0.025, P= 0.008) when compared with normal control group (0.73±0.08, 0.81±0.12, 0.80±0.03). The expressions of Cyr61 (0.75±0.05, 0.75±0.08), Beclin-1 (0.84±0.08, 0.92±0.04) and LC3B (0.93±0.16, 0.76±0.08) in rapamycin group and rapamycin + lupus group were not significantly changed ( P>0.05). Compared with rapamycin group, the protein expression of Cyr61 (0.99±0.15) was significantly increased ( P=0.016), and Beclin-1 (0.64±0.04), LC3B (0.54±0.05) was significantly decreased in lupus group ( P=0.013, P=0.001). The expressions of Cyr61 (0.75± 0.08), Beclin-1 (0.92±0.04) and LC3B (0.76±0.08) were not significantly changed in rapamycin+lupus group ( P=0.999, P=0.241, P=0.062). Compared with lupus group, the expression of Cyr61 (0.75±0.08) protein in rapamycin+lupus group was significantly decreased ( P=0.016), and the expression of Beclin-1 (0.92±0.04) and LC3B(0.76±0.08) protein were significantly increased ( P=0.002, P=0.017). Immunofluorescence results showed that Cyr61 and LC3B were mainly expressed in the cytoplasm of hippocampal neurons, and the quantitative detection results were consistent with western blot results, the differences were statistically significant ( P=0.025, P=0.032). HE staining showed that the levels and number of cells in the hippocampus of mice with lupus were reduced, and the arrangement was sparse, and the nuclei were hyperchromatic, showing nuclear pyknosis and migration. The results of Nissl staining showed that there were relatively fewer Nissl bodies, loose arrangement of neurons and vacuolar areas in some cells, which were improved after RAPA treatment in lupus mice. Conclusion:RAPA can protect the cognitive function of lupus mice by inhibiting the expression of Cyr61 in hippocampus and promoting autophagy.

Objective To observe the effect of the method of warming kidney and dredging collaterals on the clinical effect and the content of urine C5b-9 in patients with idiopathic membranous nephropathy with spleen kidney yang deficiency and blood stasis. Methods A total of 60 idiopathic membranous nephropathy patients with spleen kidney yang deficiency and blood stasis type were randomly divided into the conventional western medicine treatment group (control group), Jingui-Shenqi pill and Taohong-Siwu decoction plus conventional western medicine treatment group (treatment group), 30 cases in each group. The Scr was detected by deproteinized alkaline picric acid method, and BUN was detected by rate method, and serum albumin (ALb) was detected by bromocresol green dye binding method, and 24 hours urinary protein was measured by pyrogallol red colorimetry, and the double antibody sandwich ELISA method was used for detection of urinary C5b-9.
