Thirty-four patients with chronic lingual tonsillar hypertrophy were treated in our department from 1994 to 2000. There were 18 males and 16 females ranging in age from 21 to 60 years old. The clinical feature of lingual tonsillar hypertrophy usually appeared a series of pharyngeal symptoms, such as foreign-body sensation, sore throat, speech change, difficulty in swallowing, dysapnea and obstructive sleep apnea. The CO2 laser surgical lingual tonsillectomy was used for these patients. Result showed that the cure rate was 100% without any serious complications by following up 2 months to 3 years. The variety of presentations of lingual tonsillar hypertrophy and methods of surgical treament were discussed.

Objective To discuss the metabolic characteristics and significance of peripheral blood cell and T lymphocyte subgroup in patients with air condition disease.Methods Thirty-six patients diagnosed as air condition diseases with fever and 30 patients diagnosed as non-fever patients enrolled this study as observation group(fever group and non-fever group respectively),and 30 health population were used as control.The changes of peripheral blood cell and T lymphocyte was measured using regular blood examination and flow cytometry.Results(1)No significant diffence on white blood cell was found between the three groups(F =1.89,P =0.134);(2)The percentage of neutrophils was(68.13 ±5.67)％,(53.24 ±8.36)％ and(61.25 ±6.31)％ respectively in the fever,non-fever and control group,respectively.Compared to the non-fever and control group,the percentage of neutrophils were significantly higher(t =6.64,9.13; P =0.018,0.027 respectively).No signiciant difference in the percentage of neutrophils was found between the non-fever group and control group(P =0.356,0.125).The percentage of lymphocyte percentage was(31.66 ±7.11)％,in the fever group,which was significantly higher than those of(43.67 ±8.17)％ and(30.98 ± 8.76)％ in the nonfever and control group(t =5.59,4.98 ; P =0.022,0.021 respectively).(3)The percentage of CD4 + was (36.351 ± 6.531)％,(42.676 ± 5.169)％ and(39.253 ± 5.461)％ in the fever,non-fever and control group,respectively.The percentage of CD4 + in the fever group was significantly lower than that in the non-fever group(t =1.28,P =0.039),whereas the percentage of CD4 + in the non-fever group was significantly higher than that in the control group(t =3.80,P =0.048).The percentage of CD8 + was(28.084 ± 7.344)％,(21.186 ± 6.331)％ and(24.607 ± 7.108)％,respectively.Compared to nonfever group,the percentage of CD8+ was significantly higher(t =3.17,P =0.016).(4)The ratio of CD4 +/CD8 + was(1.629 ±0.554)％、(2.380 ± 0.391)％,and(2.079 ± 0.659)％.Compared to the non-fever and control group,the ration in the fever group was siginificantly lower(t =19.21,P ＜ 0.001 ; t =6.98 ; P =0.006),whereas compared to the control group,the ratio in the non-fever group was significantly higher(t =8.68,P =0.031).Conclusion The changes of T subgroup show the unbalance immunity function network in patients with air condition disease.

Biosplint splinting ribbons and flowable restorative were used to stabilize the mobile anterior teeth and replace the missed teeth with in 30 patients severe periodontitis.1 and 2 years after treatment the effective ratio was 86.7% and 83.3% respectively(P >0.05), probing depth and attchment loss were decreased(P <0.05).

Objective To compare the dosemetry between helical tomotherapy (HT) and intensity-modulated radiotherapy (IMRT) for early-stage postoperative breast cancer and provide more valuable evidences to the clinical researches. Methods Clinical trails of dosimetric comparing between HT and IMRT for early-stage breast cancer were obtained from PubMed, Embase, Sciencedirect, CNKI, VIP and Wanfang databases, evaluated and analyzed with the Cochrane Collaboration's RevMan 5.2 software. Results 10 studies were included with a total of 135 patients. Compared to IMRT plans, HT plans provided a significantly better conformity index (P<0.000 1), mean (P<0.000 01) and maximal dose (P=0.003) of the planning target volume (PTV). HT plans had a lower heart maximal dose (P=0.005), V20 (P=0.05), V30 (P=0.003), and ipsilateral lung maximal dose (P=0.003), V20 (P=0.02), as while as had a higher contralateral breast V5 (P=0.01), mean (P=0.05) and maximal dose (P<0.000 01). There was no significantly difference between HT and IMRT plans for homogeneity index of PTV, heart V5, V10, mean dose, ipsilateral lung V5, V10, V30, mean dose, contralateral breast V10, contralateral lung mean and maximal dose (all P >0.05). Conclusion Compared to IMRT plans, HT plans have the dosimetry superiority for early-stage breast cancer with significantly better coverage and dose conformity while maintaining lower doses to high risk organs.

Objective To explore the enhancement effects and mechanisms of IL-32β on human cervical carcinoma cells C33A to hypoxic/hypoglycemic condition.Methods After cultured in hypoxia/hypoglycemic circumstance and normal circumstance for 20 hours respectively, the mRNA and protein expression of IL-32β in C33A cells were detected by real time-polymerase chain reaction (RT-PCR) and Western blotting respectively.Trypan blue stain was used to detect C33A cells viability in hypoxia/hypoglycemic circumstance and adding 10, 100,500 ng/ml IL-32β circumstance.The xenografted tumor of nude mice was established by intraperitoneal injection, and their volumes were tested for a given time after injecting 0, 1.0 mg/kg IL-32β.siRNA was used to construct IL-32β knockdown cells and detect the expression of VEGF.Results Under the hypoxia/hypoglycemic circumstance, the expressions of IL-32β mRNA were (6.12 ± 0.03) times of the normal circumstance (F =43.16, P ＜ 0.05), the expressions of IL-32β protein were (2.23 ± 0.04) times of the normal circumstance (F =22.32, P ＜ 0.05).The C33A cells viability in hypoxia/hypoglycemic circumstance was (51.92 ± 3.41) ％, whereas, viability in 10 ng/ml IL-32β group was (55.23 ± 3.92) ％ (F =14.25, P ＜ 0.05), viability in 100 ng/ml IL-32β group was (62.52 ± 4.14) ％ (F =35.53, P ＜ 0.01), viability in 500 ng/ml IL-32β group was (69.14 ± 2.45) ％ (F =56.28, P ＜ 0.01).After 28 days, the volume of xenografted tumor of 0 mg/kg IL-32β group was (578 ± 64)mm3, and 1.0 mg/kg IL-32β group up to (1 402 ± 142) mm3 (F =27.84, P ＜ 0.01).In addition, compared with control group, the expression of VEGF in IL-32β knockdown C33A cells was significantly decreased (F =36.85, P ＜ 0.05).Conclusion IL-32β can enhance the resistance to hypoxic/hypoglycemic condition of C33A cells, which is associated with the increase of VEGF.

Objective To observe the alteration of bone metabolism and to study the pathogenesis of osteoporosis and factors in elderly patients with chronic obstructive pulmonary diseases (COPD). Methods The biochemical markers of bone metabolism, bone mineral density (BMD) of the lumbar spine and the right femur, parameters of calcaneal quantitative ultrasound(QUS), blood partial pressure and pulmonary functions in 39 male patients with COPD and 30 controls were measured. Results The broadband ultrasonic attenuation (BUA) and the speed of sound (SOS), BMD of the lumbar spines and the femur were significantly lower than that in control group. The biochemical markers of bone metabolism such as HOP/Cr, Ca/Cr, and PTH in the COPD group was significantly raised than that in control group〔(60 2?7 0)dB/MHz vs (66 5?4 9)dB/Mhz,(1 328 4?41 5)m/s vs (1 505 8?26 9)m/s,23% vs 34%,21% vs25%〕.
