Objective To investigate the necessity to test the hearing of patients whose initial symptom is tinnitus with pure tone audiometer. Methods To analyze the results of pure tone audiometer of 218 tinnitus patients.Results Among 218 cases of tinnitus patients,a total of 123 patients with abnormal hearing,among 95 cases of patients with normal hearing, except for 50 cases of tinnitus, no other cause of disease. Conclusion Among the normal hearing tinnitus patients, we should do further hearing test for them if they are not identified a clear cause of disease,such as auditory brainstem response,otoacoustic emission and other necessary checks to clear the reasons for tinnitus or the position of the unusual auditory system. It is important for early diagnosis and treatment of tinnitus. But the pure-tone audiometer should be a routine examination when tinnitus patients come for the first visit.

A total of 12 775 SSRs were identified from Scutellaria baicalensis Georgi genomic database, accounting for 2.56% of the total genomic sequences. The result showed that S. baicalensis SSRs were based on 68.32% dinucleotide and 18.63% trinucleotide repeats; CT/GA and TTC/GAA were predominant in the dinucleotide motifs and the trinucleotide motifs respectively. Nine primers were selected to produce highly reproducible SSR bands and were used in studying the genetic diversity of S. baicalensis, 50 individuals from ten populations. 68 SSR polymorphic loci were detected, these loci were polymorphic and displayed 4 to 12 alleles per locus with a mean number of 7; the effect number of alleles was 3. Expected heterozygosities were 0.6 and were far more greater than the average in dicotyledonous plants. PIC (polymorphism information content) was 0.72, Shannon's information index was 1.32, these all proved that S. baicalensis had a high genetic diversity in general. Genetic differentiation among population Gst was 0.131, genetic variation among population accounted for 13.1% and genetic variation within population accounted for 86.9%. The cluster analysis showed that 10 populations S. Baicalensis were classified into 2 groups, but it was not associated with geographical distribution.

Objective To assess the harvest method and application value of free-style anterolateral thigh perforator flap (ALTPF) in oral-maxillofacial reconstruction.Methods Fifty-three patients who suffered from oral and maxillofacial tumor underwent simultaneous reconstruction using free-style ALTPFs after radical resection from August,2013 to May,2014.Perforators of the ALTPF region were marked through hand-held Doppler probe preoperatively.Flaps were designed centered on perforators according to the defect size of the accepting site.Incisions were first made at the inner border of the designed flap.Perforators were exposed above the fascia lata femoris and then dissected retrogradely through the vastus lateralis muscle to harvest a vascular pedicle with desired caliber and length.Flap thinning was applied under microscope in some cases to compromise the need of the accepting site.Results All 53 flaps survived after transplantation while skin exfoliation occurred in 5 cases due to flap thinning.Four cases sustained partial necrosis and was cured by trimming and dressing changes.Five to 14 months' post-operative followup showed satisfactory accepting-site morphology with good speech function and swallowing recovery.All donor sites were closed primarily without skin-grafting,leaving no donor-site complications including incision disruption,scar hyperplasia and muscle strength degeneration of the lower limb.Conclusion Multiple perforators have been accu rately located preoperatively in free-style harvest approach of ALTPFs,thus optimal effects can be reached with decreased donor-site morbidity and improved aesthetic outcome to the uttermost,which accords with the refined,personalized and minimal invasive development concept of modem reconstructive surgery.

Objective:To compare the similarities and differences of clinical characteristics of human immunodeficiency virus (HIV)-negative and HIV-positive patients with talaromycosis marneffei (TSM).Methods:The clinical data of 175 inpatients diagnosed with TSM in First Affiliated Hospital of Guangxi Medical University from May 2012 to April 2019 were retrospectively analyzed. The patients were divided into HIV-positive group and HIV-negative group according to the results of HIV confirmation test. The clinical manifestations, laboratory examination indicators (white blood cell count, hemoglobin, albumin, CD4 + T lymphocyte count and C-reactive protein (CRP)) between the two groups were compared. Mann-Whitney U test and chi-square test were used for statistical analysis. Results:Among 175 TSM patients, 85 were HIV-positive and 90 were HIV-negative patients. The main clinical manifestations of fever and lymphadenopathy in the HIV-positive group and HIV-negative group were 71 (83.53%) cases and 73 (81.11%) cases, 50 (58.82%) cases and 47 (52.22%) cases, respectively, and there were both no statistical differences ( χ2=0.175 and 0.771, respectively, both P>0.05), while respiratory symptoms, weight loss and subcutaneous masses were 62 (72.94%) cases and 81 (90.00%) cases, 73 (85.88%) cases and 56 (62.22%) cases, one (1.18%) case and 16 (17.78%) cases, respectively, the differences were all statistically significant ( χ2=8.514, 12.630 and 13.737, respectively, all P<0.01). Hemoglobin in HIV-positive group and HIV-negative group were 90.50 (77.00, 113.95) g/L and 88.65 (72.85, 99.93) g/L, respectively. The difference was statistically significant ( Z=2.023, P=0.043). The ratios of albumin<30 g/L, CRP>10 mg/L in the two groups were 69.41%(59/85) and 60.00%(54/90), 94.37%(67/71) and 94.19%(81/86), respectively, and the differences were both not statistically significant ( χ2=1.693 and 0, respectively, both P>0.05). The ratios of cases with white blood cell counts >10×10 9/L and CD4 + T lymphocyte count<50/μL in the positive and negative groups were 3.53%(3/85) and 81.11%(73/90), 80.77%(63/78) and 1.75%(1/57), respectively, the differences were both statistically significant ( χ2=107.095 and 82.467, respectively, both P<0.01). Conclusions:In TSM patients, HIV-negative with subcutaneous masses, and increased white blood cell counts are common. Decreased body weight and CD4 + T lymphocyte count<50/μL in HIV-positive patients are more common than HIV-negative patients.

Objective To investigate the relationship between CT signs of portal hypertension and histopathologic stage of chronic hepatic fibrosis and cirrhosis. Methods Tri-stage enhance volume CT scan of upper abdomen was performed in 84 participants, including 48 patients with hepatic fibrosis confirmed by liver pathologic biopsy which divided into S1 (12/48), S2 (14/48), S3 (9/48) and S4 (13/48),16 patients with typical cirrhosis, and 20 healthy subjects as a control group. Measured the caliber of left and right branch of portal vein, MPV, SV and SMV at MIP images respectively, observed the collateral circulation, ascites and the size of spleen and then studied comparatively these measured parameters of different histopathologic stage. One-Way ANOVA was performed in the comparison of the vascular diameter of portal system and the size of spleen(SNK was used in the comparison between the groups). x2 test ofR × Ctable was performed in the comparison of ascites and collateral circulation among groups, and the vessel of portal system which has the greatest impact on the pathological staging of hepatic fibrosis was investigated with Logistic regression analysis. Results The caliber of left branch of portal vein, right branch of portal vein. MPV. SV and SMV were (0.98±0.11). (1.00±0.12), (1.33±0.11). (0.75±0.10).(1.07±0. 12) em respctively, the size of spleen was (128. 55±30. 56) cm<'3>, and collateral circulation and ascites were not found in control group. SV enlarged gradually in test groups and showed S1 (0. 86±0. 12) cm, S2(0. 96±0. 11) cm, S3(1.07±0.08) cm, S4(1.09±0. 10) cm, typical cirrhosis (1.18±0. 19) cm respotively. The difference between each group of S1 to typical cirrhosis and control group was significant, and the same result was seen among S3 to S4, cirrhosis and S1 to S2. Logostic regression analysis showed that the standardized regression coefficient of SV was maximum (2. 719) and had statistical significance(P <0. 01). The incidence of collateral circulati on and ascites in patients with typical cirrhosiswas significant higher than that of normal liver and every stage of hepatic fibrosis (P < 0. 05). Conclusion CT scan may be helpful for the early detection of advanced hepatic fibrosis or early stage of liver cirrhosis for patients with chronic liver disease.
