Objective · To detect gingival thickness of the anterior teeth region of Han nationality youths in Shanghai by cone-beam computerized tomography (CBCT), and evaluate its clinical application feasibility and the gingival biotype. Methods · Firstly, gingival thickness in the same site (5 participators, 30 sites) was detected by bone sounding and CBCT respectively, and the data were compared. A total of 30 participators with healthy gingival were recruited to the study and examined by the CBCT, the gingival thickness of selected sites (330 sites) was assessed and compared. All the subjects were examined by the experienced doctors and classified into three groups, thick-type middle-type and thin-type. Gingival thickness range and the proportion of every type were obtained. All data analyses were performed using SPSS 13.0. Results · There was no statistical difference in the thickness of gingival measured by bone sounding and CBCT (P>0.05). The main gingival biotypes of Han nationality youths in Shanghai were thin-type and middle-type. The average gingival thickness of upper central incisors [(1.32±0.15) mm] was larger than those of upper lateral incisors [(1.07±0.16) mm,P=0.000] and upper canines [(1.08±0.18) mm, P=0.000]. Conclusion · CBCT is feasible for detecting gingival thickness. Gingival thickness of the upper central incisors is significantly larger than those of upper lateral incisors and upper canines. The main gingival biotype of Han nationality youths in Shanghai is middle-type, the proportion of thick-type is least.

Objective To observe clinical manifestations and immune responses in rabbit models of syphilis established by inoculation with Treponema pallidum through different routes. Methods A total of 20 rabbits were randomly and equally divided into two groups: testis-inoculated group injected with Treponema pallidum (Tp) suspensions into the testes, back-inoculated group intracutaneously injected with Tp suspensions at six sites on the shaved back. All the rabbits received a single injection with the total injection amount of Tp (Nichols strains)being 2 × 107 in both groups. Clinical symptoms and immune responses were evaluated in both groups every other day. Statistical analysis was carried out by a two-sample t-test and rank sum test with the SPSS 20.0 software. Results On day 8 after the inoculation, the testes of rabbits in the testis-inoculated group started to swell with induration, and the swelling was most severe during days 13 - 16. Afterwards, the testes gradually diminished, and returned to normal in size without swelling or hardening on day 28. No skin lesions occurred in the other sites in the testis-inoculated group within 2 months after the inoculation. Erythematous swelling occurred at inoculation sites on day 7 after inoculation in the back-inoculated group, which was most obvious between days 15 and 45. Moreover, cartilage-like indurated ulcers were observed at 12 inoculation sites in 3 rabbits in the back-inoculated group, and dark-field examination of the ulcers showed the presence of Tp. There was a significant difference in the time required for the severity of lesions to peak between the testis-inoculated group and back-inoculated group (14.50 ± 1.08 days vs. 29.00 ± 10.30 days, t=5.02, P<0.05). Rank sum test showed significant differences in the distribution of highest RPR titers between the two groups(P<0.05), and RPR titers were higher in the testis-inoculated group than in the back-inoculated group. Conclusions The injection of Tp suspensions at different sites can cause different clinical symptoms and immune responses in rabbits. RPR turned positive earlier with a higher titer in the testis-inoculated group compared with the back-inoculated group. The clinical manifestations in the back-inoculated group were similar to those of chancre in primary syphilis in human.

Objective:To raise awareness of acute myeloid leukemia (AML) combined with lymphoblastic lymphoma (LBL) in children.Methods:The clinical characteristics, diagnostic methods, treatment plans and prognosis of a child with AML combined with LBL who was admitted to the First Affiliated Hospital of Zhengzhou University in April 2016 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was an 11-year-old boy with fever, abnormal hemogram and cervical lymph node enlargement as clinical manifestations. A biopsy of the cervical lymph node was performed and the patient was diagnosed as T-lymphoblastic lymphoma (T-LBL). After the bone marrow morphology, immunology, cytogenetics and molecular biology (MICM) classification examination, the diagnosis was AML. The patient met the diagnostic criteria of two diseases at the same time, and thus he was confirmed as AML combined with T-LBL. AML chemotherapy regimens were given, and the patient achieved complete remission and disease-free survived.Conclusions:AML with LBL is extremely rare in children. The diagnosis mainly depends on MICM classification examination of bone marrow and pathological examination of lymph nodes. There is currently no standard treatment scheme, and the prognosis is extremely poor. AML chemotherapy followed by bridging hematopoietic stem cell transplantation is the best treatment option for these patients.

BACKGROUND: Treatment of ulcerative colitis (UC) with herbs-partition moxibustion is of good intervenient effect, whether the effect is related to neutrophil apoptosis in the pathogenic process of UC?OBJECTIVE: To investigate the changes of neutrophil appptosis rate of rats with UC and the regulative effect of medicinal cake moxibustion. DESIGN: A randomized controlled trial based on SD rats.SETTING: Shanghai Research Institute of Acupuncture and Meridian.MATERIALS: The experiment was completed from August 2002 to June 2003. A total of 30 healthy male SD rats of clean grade, weighing (140±20) g,provided by Experimental Animal Center of Shanghai University of Traditional Chinese Medicine, were at random divided into 2 groups: model building group (n=20) and normal control group (n=10).METHODS: Rat UC models were set up with immunological method. After the models were successively set up, four model rats and two normal rats were randomly selected for pathological observation of distal colon tissue. The rest models were divided as model group and herbs-partition moxibustion group with 8 rats for each, and the rest 8 normal rats were taken as control group. The rats of herbs-partition moxibustion group were given herbs-partition moxibustion at tian shu (ST-25) of both sides and qi hai (CV-6) points; the herbs cones was made from Radix Aeoniti Praeparata,Cortex Cinnamoni, and so on. About 90 mg moxa cone was put on the herbs cones for moxibustion, once a day, for 10 times. After treatment, all rats of the three group were executed, then the peripheral monocytes were isolated for cell culture. A 1:50 diluted supernatants of each group were taken, and the same volume of RPMI-1640 culture fluid was used as blank control group. They were respectively incubated together with neutrophils of peripheral blood of normal rats. The neutrophil apoptosis rates were measured by using flow cytometry.MAIN OUTCOME MEASURES: Comparison of neutrophil apoptosis rates of rats in each group.RESULTS: Totally 20 rats in model group and 10 in normal control group were accepted. Then 4 rats in model group and 2 in normal group were sacrificed and observed with tissue pathology, and 16 and 8 rats entered the final analysis in model and normal control groups respectivelly. ① The neutrophil apoptosis rate of UC rats was significantly lower that that of rats in blank control group [(16.34±2.80) %, (52.33±9.94) %, q= -35.99, P< 0.01]; but there was no significant diffenence between normal control group [(48.79±11.33) %] and blank control group, (P>0.05). ② After treatment the neutrophil apoptosis rate of herbs-partition moxibustion group [(36.03±8.31) %] was significantly higher than that of UC model group (q=19.69, P < 0.01), but it was still lower than that of normal control group (q= -16.30, P < 0.05).CONCLUSION: One of the main mechanism for herbs-partition moxibustion to treat UC might be regulating and/or reducing the inhibited state of neutrophil apoptosis in UC.
