2.The application of three-dimensional CT in diagnosis of the branchial cleft cyst and fistula.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2015;29(15):1392-1393
The patient complained of finding on the right side of the neck fistula with discharge nine years. In recently, fistula spills significantly increased compared with the previous. Special physical examination: Right sternocleidomastoid middle 1/3 front border is seen here in a small fistula, translucence jelly secretion were spilling out when squeezeing the fistula, no smell. Ultrasound: On the right side of the upper cervical skin to submandibular gland rear could see tubular low echo area. MRI: Visible on the right side of the neck tube signal, after the submandibular gland rear. Three-dimensional CT: Visible on the right side of the neck by skin sinus crossings as deep as the tonsillar fossa lumen containing contrast agent. Clinical diagnosis: The second branchial cleft cyst and fistula.

Objective To explore the incidence rate, total incidence numbers and possible impacting factors of non-motor symptoms (NMSs) in Parkinson's disease (PD). Methods The NMS questionnaire (NMS Quest) was used to investigate 131 out-patients diagnosed with PD, and the prevalence of each item, the total NMS numbers and their relationships with clinical features were assessed. Results All of the patients, who were distributed in every stage of PD, had NMSs and each case with 11 items on average. Autonomic symptoms such as nocturia and constipation were the most frequent ones. The patients over 65 versus less than 65 years old had a higher prevalence in a number of items such as olfactory disturbance, dysphagia and constipation. At the same time, the rigidity subtype patients had a higher prevalence in depression items than the tremor subtype ones.The total number of NMS was positively correlated with course of disease, age, UPDRS score and Hoehn & Yahr (H&Y) stage. Conclusions NMSs are common among PD patients. While the prevalence of each item may vary with different clinical features, the total number of NMS is increased with the severity of PD. More attention should be paid to the diagnosis and rational treatment of the NMSs.

Objective To investigate the effect of levodopa on melanogenesis in Penicillium mameffei (PM),and to determine if melanization affects the antifungal drug susceptibility of PM.Methods A clinical isolate of PM,GXMU121011,was inoculated onto Sabouraud's dextrose agar (SDA) containing different concentrations (0.1-10 mmol/L) of levodopa at an inoculum density of 1.0 × 106 cfu/ml,or onto SDA containing 1 mmol/L levodopa at three inoculum densities (1.0 × 105,1.0 × 106,1.0 × 107 cfu/ml),and cultured at 37 ℃ for 7 days.Subsequently,melanization of PM colonies was observed.The paper-disk method was used for antifungal susceptibility testing,and the diameter of inhibition zones of itraconazole,fluconazole and amphotericin B against 8 clinical strains of PM was determined on SDA with or without levodopa.Results The melanization of PM colonies increased when the concentration of levodopa increased from 0.1 to 1.0 mmol/L,peaked when that reached 1.0 and 3.0 mmol/L,but mildly decreased when that continuously increased beyond 3.0 mmol/L,and a slight shrinkage was observed in PM colonies when that was 10.0 mmol/L.The color of colonies deepened along with the increase in inoculum density of PM.The average diameters of inhibition zones of itraconazole,fluconazole and amphotericin B against PM were all significantly lower on SDA with levodopa than on SDA without levodopa (all P < 0.05).Conclusions Levodopa concentration and inoculum density both affect melanogenesis in PM.Melanization may decrease the susceptibility of PM in yeast phase to itraconazole,fluconazole and amphotericin B in vitro.

Radiotherapy is an important treatment on gynecological tumors,especially for brachyther- apy.~(137)Cs,~(192)Ir were usually used in the past,but the local control and survival rates were not increased obvi- ously.The machines,that was made in China,of ~(252)Cf neutrons brachytherapy were used already by many hos- pitals in our country and played a preponderant role more and more.It can increase the local control and sur- vival rates effectively on gynecological tumors.

Objective:To optimize the alcohol extraction process of Yiqigutuo granules. Methods: Using the L9 (34 ) orthogonal design method, the active ingredients astragaloside and ferulic acid in the formula were quantitatively analyzed by HPLC. The concen-tration and amount of ethanol, extraction times and extraction duration and the other parameters affecting the extraction volume were ex-amined. Results:Analysis of variance showed that the ethanol concentration and extraction times had significant influence on the ex-tract content and the extraction of ferulic acid. The best alcohol extraction process was as follows:70% ethanol of 10-fold volume, ex-tracting 3 times with 1. 5h for each time. Conclusion:The process is stable, and suitable for the industrial production.

OBJECTIVETo study the protective effect of Ligustrazine Injection (LI) against cisplatin-induced ototoxicity and to explore its mechanism.
METHODSThirty healthy adult guinea pigs were randomly divided into three groups, 10 in each group, i.e., the normal control group, the cisplatin group, and the LI group. Guinea pigs in the normal control group were intraperitoneally injected with normal saline at 3 mL/kg for 7 consecutive days. Those in the cisplatin group were intraperitoneally injected with cisplatin at 3 mg/kg for 7 consecutive days. Those in the LI group were intraperitoneally injected with LI at 140 mg/kg for 7 days, but cisplatin (3 mg/kg) was intraperitoneally injected from the opposite side starting from the 4th day. Brainstem auditory evoked potential (BAEP) was performed in all animals before and after injection. All animals were sacrificed after the final testing under anesthesia and their cochleas collected. Half the cochleas of each group were collected for silver nitrate staining of cochlear basilar membrane stretched. The other half the cochleas of each group made into paraffin sections to observe the apoptosis of cochlea cells by TUNEL method and the expression levels of c-Jun detected by immunohistochemistry.
RESULTSThere was no statistical difference in the difference of BAEP threshold among the 3 groups before injection (P > 0.05), but the BAEP threshold increased in the cisplatin group and the LI group (P < 0.05). Besides, it was higher in the cisplatin group (P < 0.05). In the cisplatin group, most hair cells were missing, spiral ganglion cells obviously decreased, more TUNEL positive cells occurred, and the expression of c-Jun was stronger. But the aforesaid impairment in the LI group was obviously lessened (P < 0.05).
CONCLUSIONSLI showed certain antagonist effect on cisplatin-induced ototoxicity. Its mechanism might be associated with scavenging oxygen radicals of the cochlea tissue, improving the microcirculation, and fighting against apoptosis.
