Treated 55 cases of acute lumbar sprain only with acupuncturing Cuanzhu (BL 2). After three treatments, 53 cases were cured, and 2 cases were improvement.

Objective To retrospectively analyze medical data of patients with colorectal cancer (CRC) so as to provide evidence for clinical use of opportunistic screening.Methods A total of 2450 CRC patients (male 1377,female 1073) who were treated at five hospitals in North China during October 2001 and September 2011 and had complete medical records and pathological results were recruited.The correlations of incidenceofCRCwithage,gender,tumorlocationandhistologicaltypeswere analyzed.Results Of all the CRC patients,those less than 50 years old accounted for 18.14％ ; and the incidence of CRC was substantially increased in those over 50 years old.Seventy-three percent of tumor occurred at the rectum and sigmoid colon,6％ at descending colon,7％ at transverse colon and 14％ at ascending colon.Moderately,well or poorly differentiated adenocarcinoma accounted for 50.33％,40.35％and 9.32％,respectively.Histological differentiation was not correlated with age and gender ( P ＞ 0.05 ).Conclusions Age and gender should not be considered a determination of opportunistic screening for CRC.Colonoscopy is recommended as an alternative CRC screening procedure.

Objective To study the very early diagnosis of acute myocardial infarction (AMI) by harmonic imaging integrated backscatter(IBS).Methods Thirty normal persons,12 cases at the very early stage of AMI (in 2 hours),36 cases with AMI (in 2-12 hours) were examined by IBS and the cyclic variation of integrated backscatter (CVIB) with HP Sonos 5500 ultrasonic system in different areas (the areas of myocardial infarction and no myocardial infarction).Results In the areas of AMI of the very early stage (in 2 hours),IBS was much higher than that of the areas of normal (14.7 vs 8.3,P

OBJECTIVE To explore the effect of gene therapy on the nasopharyngeal carcinoma (NPC) cell line CNE-2 by using the combination of TRAIL gene with hTERT promoter. METHODS Total RNA was ex-tracted from PBL (peripheral blood lymphocytes)whose proliferation had been stimulated. TRAIL gene with interleukin 2 signal peptide gene was amplified by RT-PCR and cloned into the vector pGL3-181hTE down-stream to the RT promoter to form an eukaryotic vector. The vector was transfected into CNE-2 cells and HL-7702 cells through lipofection. Flow cytometry (FCM), agarose gel electrophoresis and cell morphology were used to examine the cell apoptosis. RESULTS In tranfected nasopharyngeal carcinoma cells CNE-2, FCM analysis showed that apoptotic peak appeared before G1 phase. A ladder-like pattern of DNA fragmentation appeared upon agarose gel electrophoresis. Many cells exhibited apoptotic changes such as cell shrinkage , nulear condensation , and nuclear fragmenta-tion under transmission electron microscope (TEM). CONCLUSION The recombinant eukaryotic ex-pression vector for TRAIL gene driven by hTERT pro-moter was successfully constructed and shown to induced apoptosis in CNE-2 cells. The results suggest that TRAIL may be a promising target for gene therapy of NPC.

OBJECTIVE: To investigate the clinical relationship between allergic rhinitis and allergic factors with chronic rhinosinusitis with or without nasal polyps. METHOD: Two hundred patients were divided into A and B two groups. Group A of 110 patients was diagnosed allergic rhinitis. Group B of 90 patients was diagnosed chronic sinusitis with or without nasal polyps. Serums sIgE was detected with EUROIMMUN, and observe the recurrence rate of chronic sinusitis with or without nasal polyps patients who accept operation treatment and observe the incidence of allergic rhinitis superinduced chronic sinusitis with or without nasal polyps. RESULT: The total positive rate of group A sIgE was 89.09%. The total positive rate of group B sIgE was 74.44%. The postoperative recurrence rate of sIgE positive group was 58.21% and the postoperative recurrence rate of sIgE negative group was 8.70% in the group B. In the group A, the positive rate of serums sIgE in allergic rhinitis with chronic sinusitis with or without nasal polyps (37.27%) was 97.56%, while the positive rate of serums sIgE in allergic rhinitis without chronic sinusitis (62.73%) was 79.71%, there is a significant difference in allergic rhinitis with or without chronic sinusitis (χ2 = 6.96, P < 0.01). CONCLUSION There is a certain correlation between allergic rhinitis and allergic factors with chronic sinusitis with or without nasal polyps. Therefore, through avoiding allergen exposure, the treatment of allergic rhinitis can effectively control recurrence rate of chronic sinusitis and nasal polyp.

OBJECTIVE: To investigate the treatment of benign positional paroxysmal vertigo of posterior semi-circular canal by Epley maneuver combined with Semont maneuver. METHOD: One hundred and fifty patients with benign positional paroxysmal vertigo of posterior semicircular canal were randomly divided into three groups: group A, B and C. Patients in group A were treated by Epley maneuver and patients in group B were treated by Semont maneuver. Patients in group C were received the treatment of Epley maneuver combined with Semont ma- neuver. We recorded the times of treatments in different groups respectively. Statistics of treatment effects and follow-up studies with 3 months after the recovery were assessed. RESULT: The cure rate of the canalith repositioning on the primary, secondary and tertiary treatment in group A was respective 72% (38/53) and 81% (43/53) and 85% (45/53), in group B was 68% (30/44) and 80% (35/44) and 84% (37/44), in group C was 89% (47/53) and 94% (50/53) and 98% (52/53). The cure rate in group C is significantly higher than group A and group B (χ2 = 6.777, P < 0.05; χ2 = 6.647, P < 0.05). 3 months after recovery 6 patients in group A, 5 patients in group B and 1 patient in group C were relapsed. CONCLUSION By the use of Epley maneuver combined with Semont maneuver in the treatment of benign positional paroxysmal vertigo of posterior semicircular canal, the primary cure rate was increased and the numbers of treatments were reduced and the relapse was decreased. It is suitable to use Epley maneuver combined with Semont maneuver in the clinic.

Objective To investigate the effect of pregnancy and spontaneous delivery on the morphologic characteristics of the levator ani muscle and innervation of the vaginal mucosa. Methods Eight nullipara without pelvic floor dysfunction (PFD) and 64 normal primipara undergoing spontaneous delivery were enrolled in this study during July to December 2006 in Peking Union Medical College Hospital. Biopsy specimens of levator ani muscle (LAM) and anterior and posterior vaginal walls were obtained from the puerpera as well as from the 8 nullipara undergoing vaginal operation. The structures of LAM were examined with histological techniques. Vaginal mucosa specimens were examined using immunohistochemistry staining for protein gene product 9. 5 ( PGP 9. 5), vasoactive intestinal poptide (VIP) and ne uropeptide Y ( NPY),and the positive stained nerve fibers were calculated respectively. Results The LAMs of the puerpera undergoing spontaneous delivery presented myogenetic and neurogenetic changes, both acute and chronic.Type Ⅰ muscular fibers were predominant(79% )with both types increasing in diameters [ (86±9)μm and (79±15) μm]. Significantly different ( P < 0. 05 ) innervation of PGP 9. 5, VIP, and NPY nerve fiberswas observed between epithelial lamina of anterior vaginal wall(5.9±3. 3, 7. 6±3. 1 and 8. 2±3. 2, respectively) and that of posterior vaginal wall (3. 8±2. 9, 5.9±3. 1 and 6. 0±3.0, respectively), with the nerve fibers being more in epithelial lamina of anterior vaginal wall, while no difference in the innervation of nerve fibers was observed in the lamina propria. Significantly different( P <0. 05 ) innervation of PGP 9. 5 and VIP nerve fibers was observed in the lamina propria of the anterior vaginal wall in puerperal undergoing vaginal delivery (6.9±3.2 and 4.9±2. 1) compared with those in nullipara (3.9±3.6 and 3. 1±1.2). Conclusions Pathologic changes occur in LAMs and pelvic floor nerves during labor and delivery. LAM fibers become hypertrophy to adapt to the physiological changes during pregnancy. Richer innervation of PGP 9. 5 and VIP nerve fibers in the lamina propria of the anterior vaginal wall in puerpera undergoing spontaneous delivery is beneficial for dilation of the blood vessels and smooth muscles and makes preparation for delivery.

OBJECTIVE: To study the change of endogenous hydrogen sulfide (hydrogen sulfide, H2S) and its rate-limiting enzyme Cystathionine-gamma-lyase (CSE) in allergic rhinitis through guinea pigs with intervention treatment. METHOD: Twenty-four guinea pigs were divide into 4 groups at random, one group were models of allergic rhinitis (AR) which were established by using ovalbumin, the second group were treated with NaHS after sensitized, the third group were treated with Propargylglycine (PPG) which was suppression of CSE after sensitized, and the last group were treated with saline for control. The concentration of eotaxin of nasal lavage and H2S in plasma were recorded, and then the expression of CSE in nasal mucosa was determined by real-time fluorescence RT-PCR. RESULT: The concentration of eotaxin in nasal lavage of sensitized group were higher than those of control (P < 0.01), and concentration of H2S in plasma and expression of CSE in nasal mucosa were lower than control (P < 0.05). The concentration of eotaxin decreased when treated with NaHS and increased when treated with PGG (P < 0.05). Level of H2S in plasma and expression of CSE increased when treated with NaHS and decreased when treated with PGG (P < 0.05), and the level of H2S was positive linear correlate with the expression of CSE. CONCLUSION Endogenous H2S perhaps plays a significant role in the pathogenesis of allergic rhinitis, and it was mainly regulated by CSE.

Objective To observe among stroke survivors the timing of muscle activation at the stance phase during walking using the surface electromyography ( sEMG) combined with 3D gait analysis. Methods Twenty stroke survivors assessed as at Brunnstrom stages Ⅲ, Ⅳ and Ⅴ were assigned to groups designated Ⅲ, Ⅳ and V. sEMG and 3D gait analysis were used to assess the activation timing of the bilateral rectus femoris ( RF) and biceps femoris ( BF) , the tibialis anterior ( TA) and the gastrocnemius medialis ( GM) . The activation timing and the dura-tion of activation of the muscles were compared among the 3 groups, as well as with those of healthy muscles. Results The onset time of the RF on the affected side was significantly later than on the healthy side, while that of the GM was significant earlier. The durations of BF and GM activation on the affected side were significantly shorter than on the unaffected side in group III. The onset times of the TA and GM on the affected side were significantly ear-lier than on the healthy side in group IV, as was the onset time of the TA of the affected side in group V. The average RF and BF onset times on the affected side in group Ⅳ were significantly earlier than in group Ⅲ. The onset time of the TA on the unaffected side and the average BF onset time on the affected side in group Ⅴ were significantly later than in group IV. The onset time of the RF and TA on the unaffected side in group Ⅳ and the onset time of the GM on the affected side were significantly later than in group III, while the onset time of the BF and TA on the affected side was significantly earlier. The average duration of BF activation on the unaffected side in group Ⅳ was significant-ly shorter than that of group Ⅲ. The average duration of TA activation on the unaffected side in group Ⅴ was signifi-cantly shorter than that of group IV. The duration of RF activation on the affected side in group Ⅴ was significantly shorter than that in group Ⅲ, and the same was true of the RF, BF, TA and GM activation times on the healthy side. Conclusions There are significant differences in the onset and duration of muscle activation when stroke survivors at different stages of recovery walk. Some muscles are activated too early and others are over-activated. These abnormali-ties gradually disappear with the recovery of motor function.

OBJECTIVETo investigate the possibility and short-term effect of high dose chemotherapy with peripheral blood stem cell support in the preoperative therapy of breast cancer, and-its influence on the following operation and would healing.

METHODSThree patients with T(3)N(1)M(0) (III(a)), T(4)N(1)M(0) (III(b)), T(4)N(1)M(1) (IV) of breast cancer were diagnosed histopathologically. After receiving HDC/APBSCT, the 3 patients were operated on. HDC/APBSCT process included 2 cycles of FEC induction chemotherapy; PBSC mobilization, APBSC collection and cryopreservation and PBSC infusion; and high-dose chemotherapy, APBSC infusion and supportive therapy. The therapy consisted of CTX2.5 g/m(2), VP-16 600 mg/m(2), and cerboplatin 600 mg/m(2) delivered on day 1, APBSC infusion 48 h later, rhG-CSF (150 microg, BID) was administered 4 h after infusion of APBSC until WBC was higher than 10 x 10(9)/L. During HDC/APBSCT, the patients were protected in the air laminar flow room with supportive therapy of antibiotics, anti-virus and anti-fungus drugs. They left the air laminar flow room after their WBC was greater than 2 x 10(9)/L. Case 1 was treated by radical mastectomy, Case 2 by improved radical mastectomy, Case 3 by improved radical mastectomy and transplantation of skin for the large area.

RESULTSRapid recovery of bone marrow function was observed in all 3 patients. Operation was performed 4 weeks after HDC/PBSCT in Cases 1, 2 and 33 days in Case 3. No influence was seen on operative procedure and would healing, especially in Case 3 with a large area of skin transplantation. Two patients with stage III(a) and III(b) have been alive since the treatment for 30 months and the other with stage IV died of brain metastasis 16 months later.

CONCLUSIONSHDC/APBSCT as a preoperative therapy for breast cancer has no influence on the coming surgery and would healing, even on skin transplantation for a large area. It has a practical response in stage III(a) and III(b), but it is still controversial in stage IV. This method as a salvage therapy for patients with breast cancer of intemuediate or stage.
