OBJECTIVE: To investigate the feasibility and results of laryngeal functional preservation surgery for piriform sinus carcinoma with paraglottic space involvement. METHOD: Fourteen cases of piriform sinus carcinoma with paraglottic space involvement were reviewed. Laryngoplasty was performed after tumor was resected, bilater al selective neck dissections were performed at the same stage. Postoperative chemoradiotherapy was applied to 11 patients while the other 3 patients did not receive chemotherapy nor radiotherapy. The follow-up time ranged from 6 months to 5 years, and the mean follow-up time was three and a half years. RESULT: Twelve cases healed primarily while 2 cases experienced delayed heal because of pharyngeal fistula. Postoperative swallow bucking occurred in all patients, the longest gastric feeding time was 2 months. For the patients underwent postoperative chemoradiotherapy, the tumor did not recur in ten cases during the 3 years follow-up, while recurred in another case and the patient died without further treatment. Among those 3 cases without postoperative radiotherapy or chemotherapy, the tumor recurred in 2 cases during the following 6 months and chemoradiotherapy was applied, no recurrence presented in one patient, another one lost of follow-up. For the patient with recurred tumor 8 months after surgery, total laryngectomy was employed with postoperative chemoradiotherapy, the case died of tumor recurrence one and half year after the first surgery. The 3-year survival rate was 78.6%. For the vocal cord at lesion side, the mobility was noticeable in 6 patients, and visible anatomic landmark was lost in the other 8 patients. CONCLUSION Laryngeal function preservated surgery could be performed in selected cases of piriform sinus carcinoma with para-glottic space involvement in order to achieve better clinical results and quality of life.

Objective: To observe the clinical efficacy of acupuncture plus rehabilitation training in treating post-stroke deglutition disorders of qi-deficiency blood stasis pattern. Methods: Sixty-six patients with post-stroke deglutition disorders of qi-deficiency blood stasis patter were divided into an observation group and a rehabilitation group using the random number table method. The two groups both received conventional medications and supportive treatment for stroke. In addition, the observation group received acupuncture plus rehabilitation training while the rehabilitation group only received the same rehabilitation training. The interventions were conducted 3 times a week for a total of 4 weeks in both groups. They were evaluated using Kubota water swallowing test (KWST), Fujishima Ichiro food intake level scale (FILS) and symptoms score of traditional Chinese medicine (TCM) before and after treatment, and at the 1-month follow-up. The therapeutic efficacy was assessed at the 1-month follow-up. Results: The KWST grading and FILS result after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.001); the results of these two items at the follow-up were not significantly different from those after treatment in the two groups (all P>0.05). There were significant differences in the KWST grading and FILS result between the two groups after treatment and at the follow-up (all P<0.05). The TCM symptoms score changed significantly after treatment and at the follow-up compared with that before treatment in both groups (all P<0.001). The TCM symptoms grading efficacy at the follow-up was significantly different from that after treatment in the observation group (P<0.05), while the difference was statistically insignificant in the rehabilitation group (P>0.05). The TCM symptoms grading efficacy in the observation group was significantly different from that in the rehabilitation group after treatment and at the follow-up (both P<0.05). Conclusion: Based on the conventional treatment for stroke, acupuncture plus rehabilitation training or use of rehabilitation training alone both can improve the clinical symptoms in post-stroke deglutition disorders of qi-deficiency blood stasis pattern, but acupuncture plus rehabilitation training can produce more significant efficacy and better long-term efficacy in improving TCM symptoms.

Objective: To observe the effects of electroacupuncture (EA) on uterine prostaglandin F2α (PGF2α), cyclooxygenase 2 (COX-2) and nuclear factor κB (NF-κB) in rats with primary dysmenorrhea (PD) and to discuss the possible mechanism in EA intervening PD. Methods: Forty Sprague-Dawley female rats were randomly divided into a blank group, a model group, an EA group and an ibuprofen group, with 10 rats in each group. The PD model was established using estradiol benzoate combined with oxytocin in the model group, EA group and ibuprofen group. At the same time of modeling, rats in the EA group were given EA at Guanyuan (CV 4) and Sanyinjiao (SP 6) once a day for 20 min each time for 10 consecutive days. Ibuprofen was intragastrically administered once a day for 10 consecutive days in the ibuprofen group. The same amount of normal saline was intragastrically administered once a day for 10 consecutive days in the blank group and model group. The number of writhing of rats in each group within 30 min was compared on the 11th day just after the interventions. The uterine homogenate supernatant was separated and the PGF2α level was detected by enzyme-linked immunosorbent assay. Western blot was applied for the detection of the expression levels of COX-2, phospho-NF-κB p65 and NF-κB p65 proteins in uterine tissues. Results: Compared with the blank group, the number of writhing in the model group increased significantly (P<0.01), and the expression levels of PGF2α, COX-2, phospho-NF-κB p65 and NF-κB p65 proteins in uterine tissues were significantly increased (all P<0.01). Compared with the model group, the number of writhing in the EA group and ibuprofen group were significantly reduced (both P<0.01), and the expression levels of PGF2α and COX-2 protein in uterine tissues were significantly reduced (both P<0.01). Compared with the model group, the phospho-NF-κB p65 level in uterine tissues in the EA group was significantly reduced (P<0.01). Compared with the ibuprofen group, the phospho-NF-κB p65 level in the EA group was significantly reduced (P<0.01). Conclusion: The mechanism of EA for PD rats may be related to inhibiting the phosphorylation of NF-κB and reducing the levels of COX-2 and PGF2α in uterine tissues.

OBJECTIVE: To analyze the cases of anaphylactic death cases and explore the standards of judicial expertise of anaphylactic death for providing evidence for judicial expertise. METHODS: Fifty-nine cases death due to allergic reaction in Shanghai were collected. And details of medical history, clinical manifestation of anaphylactic reaction and postmortem examination findings were reviewed for all cases. RESULTS: In the 59 cases, there were 58 cases died from drug allergy, including 77.6% of them were antibiotics. The rates of treating in standard hospital and illegal clinic were 37.3% and 61.0%, respectively. The allergic symptoms were dyspnea and facial cyanosis. The time from contacting allergens to death ranged from 1 min to 3 d. The concentration of total serum IgE ranged from 50 to 576.92 IU/mL. The results of clinical manifestation and pathological anatomy had obviously changes. CONCLUSION Based on the exclusion of all other cause of death and synthetically analysis of details of cases, medical history, clinical manifestation and anatomy, the conclusion of anaphylactic death can reached. The details of cases including clinical history, exposure to allergens, and clinical manifestation play an important role in diagnosis of anaphylactic death.

To look for a more stable and convenient way of constructing short hairpin RNA expression vectors targeting the latent membrane protein-1(LMP-1) encoded by Epstein-Barr virus(pshLMP1), and to study the inhibition function of pshLMP1 expression vectors in HNE1 cells, we designed the pshLMP1 expression cassette and pshLMP1 expression vectors by both the annealing method and PCR method and then co-transfected with pEGFP-N1-1158 into HNE1 cells to observe the mRNA and protein levels of LMP-1 genes by green fluorescence analysis, RT-PCR and western blot. pshLMP1 expression vectors were successfully obtained by both methods but better cloning efficiency was achieved and fewer deletions and mutations of nucleotides were achieved with the PCR method. Furthermore, the mRNA and protein levels of LMP-1 genes were down-regulated by pshLMP1 expression vectors. According to our research, we found that the PCR method provides a more efficient way to construct pshLMP1 expression vectors which have the ability to inhibit the function of LMP-1 genes expressed in HNE1 cells, and also provides a novel application of RNA interference technology against-EBV.

Objective To explore the incidence and distribution features of neonatal phenylketonuria(PKU) and congenital hypothyroidism(CH) in Lianyungang area.Methods The heel blood samples dried on filter paper was collected from newborns after 72 hours.As the screening indicators,PKU was detected through serum phenylalanine concentration(Phe) detection by Guthrie′s bacterial inhibition assay and CH was detected through serum thyroid stimulating hormone(TSH) levels detection by time-resolved fluorometry(TRFIA) or enzyme linked immunosorbent assay(ELISA).Results Sixty-four children with CH were diagnosed and the rate of CH was 1∶2423,41 patients were examined by thyroid gland nuclein kinescope picture,among which there were 23 patients whose thyroid glands were unusal.These patients lived in 45 towns(streets),which had no difference between men and women,city and country side.A couple of twins were screened for CH;15 cases of PKU was detected with an incidence of 1∶10 339.These patients′ parents were neither consanguineous marriage nor dominance hereditary family history.Their physical and mental development were similar to the same age children after interventive treatment.Conclusions The distribution of CH and PKU is diffuse in Lianyungang.Neonatal screening is the only valid means to find patients with CH and PKU.
