Objective To explore the incidence and pathologic feature of patients with thyroid carcinoma treated at the First Hospital of Jilin University. Methods From January 2000 to July 2010,clinicopathologic data of 1018 patients with thyroid carcinoma treated in the First Hospital of Jilin University were retrospectively analyzed. Results The cases of thyroid carcinoma between 2008 and 2010 were more than 73% higher than that in the preceding 8 years. Cancer cases from January 2009 to July 2010 were more1018 cases reviewed, 976 cases were clearly classified pathologically. Papillary thyroid carcinoma, follicular thyroid carcinoma, medullary thyroid carcinoma and anaplastic thyroid carcinoma were present in 897 (91.91%), 43(4. 41% ), 22(2. 25% ) and 6(0. 61% ) cases respectively. Of the 1018 cases reviewed,804 cases were recorded with or without lymphnode metastasis. The rate of lymphnode metastasis of male and female patient were 39. 24% and 28. 64% respectively and the difference was significant( χ2 = 6. 71 ,P ＜0. 05). The rate of lymphnode metastasis of age ＜45 years and age ≥45 years were 37.65% and 23. 26%respectively and the difference was significant ( χ2 = 19. 54, P ＜ 0. 05 ). Conclusions In the past ten and a half years, the number of the thyroid carcinoma patients treated in the First Hospital of Jilin University increased year by year. The increase of papillary thyroid carcinoma was the most obvious. Thyroid carcinoma was more common among females. The peak incidence age of males and females was 30 -59. The rate of lymphnode metastasis of males was larger than that of females. The rate of lymphnode metastasis of age ＜45years was larger than that of age≥45 years.

Objective To investigate the therapeutic effects of variable-frequency electroacupuncture treatment for elderly patients with knee osteoarthritis. Methods One hundred and twenty patients with knee oste-oarthritis were randomly divided into a treatment group and a control group. The treatment group was treated with variable-frequency electroaeupuncture, while the control group was treated with muscle strength training. Before treatment and after 8 weeks of treatment, the motor function of their knee joints was evaluated according to Lysholm' s knee scoring scale, quadriceps muscle strength was evaluated according to the maximum load capacity of knee ex-tension, and postural stability was evaluated using a static balance function test. Results Lysholm scores in the treatment group improved significantly compared with those before treatment, except for the item assessing support-ing. While in the control group, compared with before treatment, there were significant differences in the items as-sessing limp, inter-locking, instability, pain and stair activity. There were significant differences in the items as-sessing inter-locking, pain, swelling, stair activity and.squatting between the two groups after treatment. The maxi-mum knee extension load improved significantly in both groups. Static balance with the eyes both open and closed also improved significantly in both groups. There were significant difference in the length, covered area, rectangle-area and length/area of the sway traces of the two groups after treatment. Conclusions Variable-frequency elec-troacupuneture can effectively improve knee function, quadriceps muscle strength and postural stability in elderly patients with knee osteoarthritis.

The gene expressions of codeinone reductase (COR) and berberine bridge enzyme (BBE) in Papaver somniferum were blocked by RNA hairpin of RNA interference (RNAi). The complete sequences of COR and BBE genes were cloned by reverse transcription-polymerase chain reaction (RT-PCR), the results of homology comparison revealed that the cloned COR and BBE genes had high homology with the other gene family members reported in the GenBank. The target sequences of COR and BBE genes were screened in accordance with the design principle of RNAi, a 643 bp fusion gene was obtained by the method of overlapping PCR, then plant expression vector ihpRNA was constructed based on intermediate vector pHANNIBAL and plant expression vector pCEPSPS. With that 78 transgenic plants were obtained through Agrobacterium-mediated and 17 positive plants were screened by PCR, that could initially indicate that the target fragments of COR and BBE gene had been integrated into tobacco genome.

AIM: To explore the expression of glucose transporter 4 (GLUT4) in the endometrium of rats with polycystic ovarian syndrom (PCOS) and evaluate the relationship between GLUT4 expression and insulin resistance (IR). METHODS: 54 female SD rats of 85 days were randomized to control group (n=20), PCOS model group (n=17) and metformin treatment group (n=17). The rats in the latter two groups were induced by Poretsky's method for PCOS model, followed by placebo or metformin, respectively. After 14 days of treatment, the rats were sacrificed and the expression of GLUT4 in endometrium was detected by ElivisionTM Plus two steps immunohistochemical staining. RESULTS: The expression of GLUT4 and insulin receptor(INS-R) proteins of endometrial glandulan epitheliu in PCOS rats were significantly lower (P

Objective To explore the effect of intraoperative parathyroid hormone (IOPTH) examination on parathyroidectomy for primary hyperparathyroidism.Methods The clinical data of 41 PHPT patients who received IOPTH monitoring (IOPTH group) from Jan.2009 to Dec.2014 were retrospectively analyzed.The clinical manifestation,examination and changes of parathyroid hormone and calcium before and after operation were collected.Results There were 12 males and 29 females.36 cases had parathyroid adenoma,and 5 cases were parathyroid carcinoma.23 cases were positive in 24 cases of 99Icm-MIBI parathyroid adenoma radionuclide examination,and 2 cases were positive in 3 cases of parathyroid carcinoma radionuclide 99Tcm-MIBI inspection (P＝ 0.213).10 mins after tumor resection,PTH in all cases decreased by 50％ or more than that before tumor resection except for one case of parathyroid carcinoma.23 cases appeared hypocalcemia in 36 cases of parathyroid adenoma after surgery and 2 cases appeared hypocalcemia in 5 cases of parathyroid cancer patients (P＝0.361).No postoperative hoarseness,cough,bleeding occoured.Patients were followed up from 6 to 72 months.Hypocalcemia symptoms recovered 2 weeks to 3 months after surgery.No permanent hypoparathyroidism occured.One case of parathyroid carcinoma died of hypercalcemia 5 months after surgery.The remaining 40 cases survived without recurrence or death.Conclusions Intraoperative PTH monitoring can help doctors analyze whether all the hyperthyroidism glands have been removed,which can help to avoid miss diagnosis of multiple gland disease and unnecessary bilateral neck exploration.This method is highly accurate so it is recommended for routine use in PHPT surgery.

A case of severe complications is presented that replaced the double J tubeless misguided by zebra guidewire into ileum in a patient with ureteral dermostomy, causing a ureteral ileum fistula.The result suggests improper operation of zebra guidewire could have a risk of ureteral perforation when the ureter is distorted, narrow or with inflammatory lesions.Standardized diagnosis and treatment and correct selection of guidewire can reduce the risk of ureteral perforation.

Objective:To evaluate the effect of noninvasive prenatal testing (NIPT) as first-line screening in fetal chromosome aneuploidy screening practice, and to provide evidence for the prevention and control strategy of birth defects.Methods:Since July 2019, Hebei province had carried out the NIPT project providing first-line screening for eligible pregnant women in the area (except for those who were not applicable). Pregnant women with high risk received genetic counseling, prenatal diagnosis and intervention guidance. Low risk and false-positive ones received continuous detection and moved to prenatal diagnosis center for counseling and diagnosis if abnormities were discovered. All pregnant women were followed up to learn about pregnancy outcomes and newborn health status. Detection results and clinical data of pregnant women participating the NIPT project from July 2019 to July 2020 were collected. The detection results and effect of NIPT were analyzed.Results:(1) Basic information of the screened population: A total of 424 330 pregnant women were screened, and 423 596 were successfully detected, with a success rate of 99.83% (423 596/424 330). The age of pregnant women was (28.8±4.5) years old; the gestational age of screening was (16.6±2.3) weeks; the proportion of advanced-age pregnant women (≥35 years old) was 10.18% (43 132/423 596); in vitro fertilization-embryo transfer (IVF-ET) rate was 1.58% (6 713/423 596); the twin rate was 1.38% (5 849/423 596); the proportion of primipara was 34.23% (144 977/423 596). (2) Screening results and detection performance: totally, 325, 73 and 20 pregnant women were diagnosed with trisomy 21, 18 and 13; the sensitivity were 99.39%, 100.00% and 100.00%; the specificity were 99.98%, 99.99% and 99.98%; the positive predictive value were 75.76%, 68.87% and 21.51%, respectively. Besides, 249 190 pregnant women were received supplementary reports as well, and 255, 10 and 9 were confirmed for sex chromosome aneuploidy, other autosomal aneuploidy and deletion/duplication syndrome; the positive predictive value were 37.78%, 6.06% and 32.14%, respectively. The sensitivity of NIPT for target trisomy (trisomy 21, 18 and 13) screening in advanced-age, IVF-ET and twin pregnant women were 99.29%, 100.00% and 90.00%, respectively; the specificity were 99.93% for all; the positive predictive value were 82.25%, 61.54% and 69.23%, respectively.Conclusions:NIPT has a significant effect and good performance in the first-line screening of fetal chromosome aneuploidy in the whole population, which might provide reference for the improvement of birth defect prevention and control strategy.
