Objective To explore the application of B-mode intra- and post-operative ultrasound in patients with traumatic brain injuries. Methods B-mode intra- and post-operative ultrasound were performed 35 times in 24 patients, including 7 times of intra-operation in 7 patients and 28 times of post-operation in 17 patients. Results During operation epidural hematomas in 3 cases as well as intracranial hematomas in 2 cases, subdural hematomas in 1 case, diffused brain swelling in 1 case were found. After operation epidural hematomas were examined in 4 cases as well as subdural hematomas in 1 case, delayed intracranial hematomas in 6 cases, scattered contusion and laceration of the brain in 12 cases, acute obstructive hydrocephalus in 1 case, and subdural hydroma in 4 cases. Six cases underwent operations again because of delayed hematomas, contusion and laceration of the brain. B-mode ultrasound was compared with CT scan and the total coincidence rate was 85.4%.Conclusions B-mode ultrasound is helpful to examine delayed hematomas and other emergent complications. It may save time and may improve rescue rate and has a good coincidence with CT scan. B-mode ultrasound may be widely used as a routine way in neurotrauma ICU.

Objective To study the expression and regulation of polycystic ovary syndrome ( PCOS) susceptibility gene Hmga2 in endometrial receptivity and decidualization. Methods Experiments including early pregnancy, delayed implantation and activation, artificial decidualization and ovarian steroid hormone treatment were performed, and Q-PCR and Western blot analyses were applied to explain the role of Hmga2 in endometrial receptivity. Results The Hmga2 ex-pression increased gradually with pregnancy. Its expression at the implantation site was significantly higher than that at the inter-implantation site,in the embryo activation group than in delayed implantation group, and in the artificial decidualiza-tion than the non-decidualization. The expression of Hmga2 was positively correlated with the expression of estrogen and progesterone, and was positively regulated by estrogen and progesterone in vivo. Conclusions Our findings indicate that the expression of Hmga2 is closely related to the embryo implantation process in early pregnancy in mice, is involved in the process of endometrial decidualization, and is influenced by the activated blastocyst and steroid hormones.

OBJECTIVETo observe the interventional effect of electroacupuncture combined with catgut implantation at acupoints for treatment of simple obesity of heart and spleen deficiency type.

METHODSSixty five cases were randomly divided into an observation group (33 cases) and a control group (32 cases). The observation group was treated with electroacupuncture combined with catgut implantation at acupoint therapy, the electroacupuncture was applied at Zhongwan (CV 12), Xiawan (CV 10), Guanyuan (CV 4), Tianshu (ST 25), ect. and catgut implantation was given at Zhongwan (CV 12), Tianshu (ST 25), Qihai (CV 6), etc. The control group was treated with electroacupuncture only. The body weight, body mass index (BMI), waistline, waist hip ratio (WHR), Pittsburgh sleep quality index (PSQI), Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD, 17 items) were evaluated before and after treatment, and these were also compared with those of 35 nomal cases.

RESULTSThe total effective rate of 93.9% in the observation group was higher than that of 84.4% in the control group (P < 0.05); the body weight, BMI, waistline, WHR, PSQI, HAMD and HAMA of simple obesity cases were obviously higher than those of normal cases (all P < 0.05). The scores of above indexes were all obviously decreased in both groups after treatment (all P < 0.05), and the improvement was more significant in observation group (P < 0.05).

CONCLUSIONThe sleep quality reduction and mental and psychology disorder exist in simple obesity patients, and electroacupuncture combined with catgut implantation at acupoints can reduce weight effectively, and at the same time improve the sleep quality and regulate psychological state.

U251 cell is a sensitive cell line to serum, which stops at G0 phase of cell cycle in no-serum medium, and recovers growth when the serum is added into no-serum medium. The cell can express corresponding proteins in different phase of cell cycle. Therefore it is very signification for the study of cell cycle regulation mechanism that explores these proteins. In this paper, the mouse antibody phage display library was added into the bottle in which the serum starvation U251 cells had been cultured, and the special antibody phages were absorbed. Then the absorbed antibody phages were amplified by adding E. coli TG1 and helper phage M13K07. Amplified antibody phages were added into bottle in which the serum cultured cell after serum starvation (follow named as serum recovered cells) were incubated, so that the cell absorbed the no-special antibody phages for the serum starvation cell and the special antibody phages were in supernatant. The remaining no-special antibody phages in the supernatant were discarded by repeating above program 3-4 times. The pure special antibody phages were gotten, and amplified by adding the host cell E. coli TG1 and helper phage M13K07. Then the host bacterium infected special antibody phage was spread on the plate medium with ampicillin, and the monoclonal antibody phages were gotten. Using same as above program, the monoclonal antibody phages absorbed specially for serum recovered U251 cells were obtained when the serum recovered cells instead of serum starvation cells and serum starvation cells instead of serum recovered cells. In this study, ninety-six positive monoclonal antibody phages that absorbed specially the serum starvation cells and eighty-two positive monoclonal antibody phages that absorbed specially the serum recovered cells were obtained. By using cell immunochemistry assay, two special signification antibodies were obtained. one (No.11) was the strong response in serum starvation cells, the other (No.2) was the strong response in serum recovered cells. The antibody No.2 had the distinctive response to the serum recovered cells in different incubation time (15min, 30min, 1h, 2h, 4h, 8h, 12h and 48h) after serum starvation. The results showed that No.2 antibody would be useful to research the factors of cell cycle regulation and apply to tumor diagnosis.

OBJECTIVETo explore a new method for mentoplasty.

METHODSThe bilateral prominent mandibular angle or outer lamina was resected through the intraoral approach. The resected bone fragments were shaped and rigid fixed to the chin with miniplates and screws.

RESULTSA total of 30 patients (28 females, 2 males) accepted chin augmentation with this method. The mandibular angle bone was used in 20 cases and the mandibular outer lamina was used in 10 cases. The operative results were satisfactory, and the patient's facial contour was improved substantially.

CONCLUSIONNo rejection reaction was found after this procedure. Chin augmentation with autogenous mandibular bone is an ideal method for genioplasty.

OBJECTIVETo study the clinicopathologic features of sclerosing angiomatoid nodular transformation of spleen and its differential diagnosis.

METHODSThe clinicopathologic characteristics and immunophenotype of 4 cases of sclerosing angiomatoid nodular transformation of spleen were studied.

RESULTSHistologically, all cases were characterized by multiple angiomatoid nodules of various sizes in a fibrosclerotic stroma. The nodules were round and sometimes convoluted. They were composed of slit-like, irregular-shaped or slightly dilated vascular spaces lined by plump endothelial cells and interspersed with a population of spindly or ovoid cells. Immunohistochemical study showed a heterogeneous staining pattern, with the lining cells of the small capillaries expressing CD34 and those of the sinusoid-like structures expressing CD8. CD31 highlighted both the lining cells and interspersed cells, resulting in a complex meshwork. The lining cells were also focally positive for CD68. Smooth muscle actin revealed conglomerates of spindly shaped cells around and between the vascular channels. These spindly shaped cells in the intervening stroma were focally positive for actin, but negative for desmin, CD21 and CD35.

CONCLUSIONSSclerosing angiomatoid nodular transformation is a rarely encountered benign lesion of the spleen, which should be distinguished from other angiomatoid tumors and tumor-like lesions.

OBJECTIVETo study the surgical reconstruction of secondary fracture deformities of the nasal-orbital ethmoid area.

METHODSTypical bicoronal and subciliary incisions or the adjacent scar incision were employed to expose the fractured area. The flattened nasal bone was narrowed by curved osteotomy along the medial orbital rims and trimed with a bur. 2-3 pieces of cranial outer table were used to reconstruct the nasal framework, which were fixed to the frontal bone with mini-plates. After the medial orbital wall and orbital floor were exposed, the herniated orbital contents were released and reduced to the orbital cavity. The fractured orbital walls were repaired precisely with autogenous cranial outer table or Medpor. The medial canthal tendons were anchored superior-posteriorly to the lacrimal fossa with transnasal wires.

RESULTSFrom December 1996 to December 2001, 34 cases of severe nasal-orbital ethmoid fracture deformities were repaired with this technique. Of them, 12 cases had combined orbital-zygomatic fracture, 4 cases had fontal sinus fracture, 1 case had Le Fort II and 1 case had Le Fort III fracture. All the patients recovered well and their facial appearance improved greatly.

CONCLUSIONSThe key points for surgical reconstruction of the periorbital post-fracture deformities are narrowing the flattened nasal root by curved osteotomy, the nasal framework reconstruction with autogenous bone graft, the orbital wall repair to correct enophthalmos, and most importantly, the medial canthal tendon reduction and canthal plasty.

OBJECTIVETo observe the clinical efficacy of acupuncture at Jiaji (EX-B 2) points mainly for lumbar myofascial pain syndrome (MPS).

METHODSSixty-six cases of MPS were randomized into an acupuncture group and a lidocaine group, 33 cases in each group. The acupuncture group was treated with acupuncture at Jiaji (EX-B 2) points combined with needling local myofascial trigger points (MTrP), and the lidocaine group was treated with local block at trigger points with lidocaine injection. The treatment was given once every 2 days. After three and five times of the treatment, the simplified McGill scale, Oswestry disability index (ODI) and pressure-pain threshold were assessed to compare the therapeutic effects between the two groups.

RESULTSAfter treatment, the scores of simplified McGill and ODI of two groups were obviously reduced while the score of pressure-pain threshold was obviously increased (all P < 0.01). After three and five times of the treatment, there were no significant differences in above scores between the two groups (all P > 0.05).

CONCLUSIONAcupuncture at Jiaji (EX-B 2) points combined with needling MTrP is an effective and safe therapy for lumbar MPS, the therapeutic effect is equal to lidocaine block.
