Objective To summarize the experience on diagnosis and treatment of primary hyperparathyroidism(PHPT).Methods Clinical data of 91 PHPT patients treated in Beijing Jishuitan Hospital from November 1992 to December 2008 were analyzed retrospectively.Results Among 91 PHPT cases,88 were diagnosed as parathyroid adenoma(96.7%),3 were diagnosed as parathyroid carcinoma (3.3%).Serum calcium and PTH levels increased in all cases.Main clinical manifestations were osteodynia and kidney stones.The accuracy rate of preoperative B-ultrasound.CT and ECT~(99m)Tc-MIBI on location was 83.5%(76/91),60.9%(14/23)and 98.6%(69/70)respectively.Parathyroidectomy was performed in all but one cases,in which parathyroid carcinoma was managed by ipsilateral hemithyroidectomy and modified neck dissection.The cure rate of primary operation was 97.8%(89/91).Ninety cases were followed-up from 8 months to 14 years postoperatively,87 cases with parathyroid adenoma achieved complete remission,2 with parathyroid carcinoma suffered from tumor recurrence and 1 died.Conclusion Patients with chronic bone diseases,repeatedly recurrent nephrolithiasis,peptic ulcer disease should be a suspect of PHPT.The routine examinations of serum calcium and phosphorus are to be conducted.UItrasonography and ECT~(99m)Tc-MIBI should be considered as the methods of first choice for preoperative localization.

Objective To investigate the clinical efficacy of Nazi method of midnight-midday ebb flow plus warm needling moxibustion in treating transient ischemic attack (TIA). Methods Sixty patients with transient ischemic attack were randomly allocated to treatment and control groups, 30 cases each. The control group received routine medication and the treatment group, Nazi method of midnight-midday ebb flow plus warm needling moxibustion in addition. The main clinical symptoms were observed by TCD monitoring of microembolic signals in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results After treatment, the positive rate of microembolus monitoring was 3.3%in the treatment group and 20.0%in the control group;there was a statistically significant difference between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the traditional Chinese medical syndrome score in the two groups (P<0.05). There was a statistically significant post-treatment difference in the traditional Chinese medical syndrome score between the treatment and control groups (P<0.05). The total efficacy rate was 96.7% in the treatment group and 80.0% in the control group;there was a statistically significant difference between the two groups (P<0.05). At six months after treatment, the rate of disappearance of TIA, the rate of recurrence of TIA and the rate of occurrence of cerebral infarction were 90.0%, 6.7%and 3.3%, respectively, in the treatment group and 60.0%, 20.0%and 20.0%, respectively, in the control group;there were statistically significant differences between the two groups (P<0.05). Conclusions Nazi method of midnight-midday ebb flow plus warm needling moxibustion can decrease the positive rate of microemboli and shorten transient ischemic attack to prevent cerebral infarction in patients with transient ischemic attack.

Objective To investigate the possibility of microsatellite alteration (MA) in diagnosis of bladder cancer of Chinese people, and find the better panel which will be used in clinic. Methods A total of 6 and 10microsatellite markers were chosen, PCR-SSLP silver staining assay was performed in 31 and 32 bladder cancers tissue,exfoliate cells in urine and 10, 15 non-bladder cancers exfoliate cells in urine, respectively. Results MA (+) was found in 28 out of 31, 30 out of 32 bladder cancers, and the sensitivity was 90.3%, 93.7% respectively. The MA of urine sediment of 25 non-bladder cancers was negative, and the specificity was 100%. The cytology was carried out among 19 out of 31, 20 out of 32 bladder cancers at the same time, 2 cases ( 10.3 %) and 3 cases ( 15 % ) were found cancer positive, and the sensitivity is significantly lower than that by the analysis of MA in exfoliated cells. Conclusion MA was not associated with grade and stage of the bladder cancer. MA assay is a sensitive and effective method for the early detection of bladder cancer and post-operation surveillance.

Objective To observe the application of amniotic membrane in conjunctival sac plasty.Methods 24 cases with different eye diseases were performed with conjunctival sac plasty,in which 11 eyes were performed with amniotic membrane transplantation,5 eyes with symblepharon which adhered with cornea or emerged neovascularization were performed with amniotic membrane transplantation and lamellar keratoplasty,other 8 eyes were performed with amniotic membrane transplantation and conjunctival fornixe.They were followed up for 6~12 months.Results There was no inflammation observed after operation.The transplanted amniotic membrane turned transparent and the conjunctiva at sewing location crawled to amnion 10 d after operation.One month later,the neonatal conjunctiva covered transplanting region completely.Among the 24 eyes,9 eyes were healed,13 eyes were improved,and 2 were ineffective.Conclusion Amniotic membrane is a kind of effective material during conjunctival sac plasty for narrow conjunctival sac.

OBJECTIVE To explore the role of P38MAPK inhibitor on the soft palate reconstruction of the rats with chronic intermittent hypoxia. METHODS The animals were divided into normal control group, hypoxia control group and SB203580+hypoxia group (every group 20 rats). After 5 weeks, the expressions of p38MAPK and p-p38MAPK protein on the soft palate of the rats were detected with immunohistochemical techniques and western blot. RESULTS Compared with the normal control group, the soft palate tissue thickness of the hypoxia group were increased most obviously; Levels of p38MAPK were increased in hypoxia control group; Compared with the hypoxia control group, the levels of p-p38MAPK group were decreased in SB203580+hypoxia group. CONCLUSION p38MAPK may play important roles in the soft palate reconstruction of the rats with chronic intermittent hypoxia.

Maca as one of the star products in the international health care market in recent years, had a wide range of application value and promoted to all over the world.
