Objective To observe the curative effect of Jiawei-Haiqi pill on senile osteoporosis. Methods 124 patients in Shantou hospital of Traditional Chinese orthopedics were gathered from May 2010 to December 2012 in accordance with the criterion of diagnosis of senile osteoporosis. The 124 patients were divided into 2 groups randomly according to their case number. Sixty cases in the study group were treated with Jiawei-Haiqi pill, 6 gram per time once a day. Sixty-four cases in the control group were given 50 IU salmon calcitionin see calcimar via intramuscular injection once a day in the fist week, once every two days in the second week, and once every three days in the third week. Both groups were treated for 3 weeks with 3 months visit. After the end of treatment, symptom score, record the bone mineral density and biochemical markers of bone metabolism(serum alkaline phosphatase(ALP), Fasting bone gla protein(BGP), Urinary calcium(UCa) were observed in both groups. Results ①Comparison of curative effect of osteoporosis: After 3 weeks treatment, the total effective rate was 85.0%(51/60) in the study group and 79.7%(51/64) in the control group. There was no significant difference(P=0.776) between the two groups. ②Comparison of bone mineral density effect:the total effective rate was 40%in the study group and 39.1%in the control group.The difference between the two groups was not statistically significant(P=0.991). ③Bone mineral density and symptom score changes bone mineral density in the two groups after 3 weeks and 3 months treatment [The study group respectively(0.69±0.08)g/cm2, (0.70±0.10)g/cm2, the control group respectively(0.69±0.0)g/cm2, (0.70± 0.13)g/cm2] increased than those in the same group before treatment[The study group (0.69±0.05)g/cm2, the control group (0.69±0.10)g/cm2], but there were no significant difference within group and between group comparisons(P>0.05);symptom score in the two groups after 3 weeks and 3 months treatment [The study group respectively(9.90±2.00)min,(8.50±1.70)min, the control group respectively (10.40±2.40)min, (9.00±1.90)min] reduced than those in the same group before treatment[The study group(16.10±2.00)min, the control group (16.20±1.80)min] (P<0.05), but there were no significant difference within group and between group comparisons(P>0.05). ④Biochemical markers of bone metabolism changes, after 3 weeks treatment, BGP in the study group(9.08±5.05)ρ/(?g?L)increased than that before treatment (5.10±3.50)ρ/(?g?L)(P<0.05). Conclusion Jiawei-Haiqi pill could effectively improve the clinical symptoms of aged patients with osteoporosis and elevate the levels of their BGP.

Objective To observe the effect of electric-impulse stimulation to Jiaji points (EX-B2) on spinal cord injury (SCI). Methods Totally 126 eligible SCI patients were randomized into a treatment group and a control group, 63 cases in each group. The control group was intervened by conventional rehabilitation training plus acupuncture, while based on which the treatment group additionally received electric-impulse stimulation to Jiaji points (EX-B2). The spasticity, function, and activities of daily living (ADL) were evaluated 90 d later. Results The spasticity score was significantly changed after intervention in the treatment group(P＜0.01). Tendon reflex and spasticity score were significantly changed in the control group (P＜0.01). After intervention, there was a significant difference between the two groups in comparing spasticity score (P＜0.01). The changes of motor function and sensory function scores in the treatment group were significantly different from that in the control group (P＜0.01, P＜0.05). The Barthel Index (BI) scores were significantly changed in both groups after intervention (P＜0.05). There was a significant difference in comparing the BI score between the two groups after intervention (P＜0.05). Conclusion Electric-impulse stimulation to Jiaji (EX-B2) plus conventional rehabilitation training can significantly improve spasticity, and the motor and sensory functions, and promote the recovery of activities of daily living.

Objective To study the diagnosis and treatment of retroperitoneal schwannoma.Methods Clinical data of 11 cases of primary retroperitoneal schwannomas were analyzed retrospectively from February 1990 to September 2014.There were 6 males and 5 females,with a median age of 46 years,and the median tumor size was 9.6 cm (4.5-12.3 cm).Seven cases were revealled due to physical examination,3 cases were revealled due to ipsilateral lower back pain or discomfort,and 1 case was revealled due to right lower extremity numbness.There were no clinical manifestations of hypertension or appearance shape change,and there were no abnormal findings in routine laboratory and endocrine examinations.Radiological examination showed a retroperitoneal mass.There were 3 cases in the left adrenal gland,1 case in the right adrenal gland,3 cases in the lower pole of left kidney and 4 cases in the lower pole of right kidney.Four patients were initially diagnosed as adrenal tumors,and 7 patients were diagnosed as kidney tumors.Results All the 11 cases underwent surgical resection,with 7 cases of complete resection,1 case of capsule resection,2 cases of partial resection and 1 case of biopsy.The pathology of immunohistochemical staining showed S-100 positive in 10 cases of benign retroperitoneal schwannomas.During the follow-up period for 1.5-24 years (median 14 years),no recurrence and malignance was observed.One case of malignant retroperitoneal schwannoma died of multiple metastases in 17 months after opreation.Conclusions Primary retroperitoneal schwannoma is rare and preoperative diagnosis is difficult.Clinical manifestations and radiological findings are usually nondiagnostic,and histopathology is the only way for final diagnosis.Complete surgical resection is proved to be the best choice.

Objective:To assess the metabolic side effects of the following atypical antipsychoties head-to-head:amisulpride,olanzapine,aripiprazole,quetiapine,risperidone,ziprasidone.Methods:We searched the MED-LINE,EMBASE,Cochrane Library,PubMed,CNKI,Web of science,Sinomed,WANGFANG DATA databases for randomized,blineded studies comparing the above mentioned atypical antipsychoties in the treatment of schizophre-nia or related disorders.At last three reviewers extracted the data independently.All the data would be analysed with meta ananlysis and the analysis software of the RevMan 5.1 provided by Cochrane network.Results:There were 49 studies in which 45 were written in English and 4 were written in Chinese included in the review.Olanzapine pro-duced statistically significantly more weight gain than all other second-generation antipsychotics.Risperidone pro- duced significantly more weight gain than amisulpride.Olanzapine produced statistically significantly more increase in glucose levels from baseline to endpoint than all other second-genetation antipsychotics.Risperidone produced statistically significantly more increase in glucose levels from baseline to endpoint than aripiprazole,quetiap-ine.Olanzapine produced statistically significantly more increase in cholesterol than aripiprazole,risperidone and zi-prasidone.Quetiapine produced significantly more increase in cholesterol than risperidone and ziprasi-done.Risperidone produced significantly more increase in cholesterol compared to aripiprazole and ziprasidone.Conclusion:Some atypical antipsychoties lead to substantially more metabolic side effects than other a-typical antipsychoties.When choosing an atypical antipsychotic agent for an individual patient these side effects with their potential cause of secondary diseases should be weighed against efficacy and characteristics of the individual patient.

Objective To compare the effects of flexible ureterorenoscope holmium laser for treatment of different sizes lower pole caliceal stones. Methods 140 patients with lower pole caliceal stones from August 2011 to April 2015 were enrolled, 40 patients were divided into observation group which the largest stone diameter > 2.0 cm, 100 patients were divided into control group which the largest stone diameter ≤ 2.0 cm. All these patients received flexible ureterorenoscope holmium laser treatment. Then we observe and compare the prognosis. Results The postop﹣erative 3 d and 1 month of gravel success rates were 97.5 % and 80.0 % in observation group, while the control group were 98.0% and 95.0%. The postoperative 1 month of gravel success rates in observation group was signifi﹣cantly lower than that in control group (P< 0.05). The operative time and postoperative hospital stay in observation group were significantly higher than control group (P<0.05). The postoperative 1 month complications of lung infec﹣tion, hematuria, urinary extravasation and so on in observation group were significantly higher than that in control group (P<0.05). The postoperative 3 d creatinine contents in observation group were significantly higher than preop﹣erative (P< 0.05), and significantly higher than that in control group (P< 0.05). The creatinine contents compared between the two groups at other time points were not statistically significant (P> 0.05). Conclusion Compared with small lower pole caliceal stones, the success rate of flexible ureterorenoscope holmium laser treatment of large lower pole caliceal stones is declined, the patients also have some trauma, and the renal function is also fluctuate, postop﹣erative disease is relatively higher that clinically to be carefully chosen.

Abstract: Objective　To explore the epidemiological and clinical characteristics of non-tuberculous mycobacterial(NTM) pulmonary disease in Hainan in recent years, and to provide data support for the prevention and treatment of NTM pulmonary disease. Methods　Medical records of patients diagnosed with NTM pulmonary disease who treated at the Second Affiliated Hospital of Hainan Medical University (Hainan Provincial Tuberculosis Hospital) from January 2018 to December 2022 were collected. The demographics, regional distribution, temporal distribution, distribution of mycobacterial species, clinical symptoms, and radiological imaging changes of these patients were analyzed. Results　A total of 225 confirmed cases of NMT pulmonary disease were collected in this study, with 133(59.1%) female patients outnumbering 92(40.9%) male patients. The disease predominantly affected people over 50 years old, with 192 cases (85.3%), and the major onset age range was 61-<81 years old, with a median age of 63 and an average age of 62. Farmers comprised the majority of the patients, with 112 cases (49.8%). More patients were from the western region (90 cases, 40.0%) than from the central region (76 cases, 33.8%), followed by the eastern region (59 cases, 26.2%). A total of 10 strains were detected from 225 samples, with the most common strains being Mycobacterium intracellulare (92 cases, 40.9%), Mycobacterium chelonae/abscessus(80 cases, 35.6%), and Mycobacterium avium (15 cases, 6.7%), followed by Mycobacterium kansasii (5 cases, 2.2%), Mycobacterium fortuitum (4 cases, 1.8%), and Mycobacterium parascrofulaceum (3 cases, 1.3%). There were 10 cases (4.5%) of mixed infections, including Mycobacterium avium and Mycobacterium intracellulare (8 cases, 3.6%), Mycobacterium intracellulare and Mycobacterium chelonae/abscessus (1 case, 0.4%), and Mycobacterium fortuitum and Mycobacterium chelonae/abscessus (1 case, 0.4%). The primary clinical manifestations of NTM pulmonary disease included cough and sputum (219 cases, 97.3%), hemoptysis (92 cases, 40.9%), fever (61 cases, 27.1%), dyspnea (57 cases, 25.3%), night sweats (52 cases, 23.1%), weight loss (50 cases, 22.2%), and thoracodynia (35 cases, 15.6%). There was no significant difference in symptoms between male and female patients. Pleural thickening (188 cases, 83.6%) and bronchiectasis (151 cases, 67.1%) were the most common imaging changes in NTM pulmonary disease, followed by cavities (93 cases, 41.3%), emphysema (41 cases, 18.2%), and lung damage (28 cases, 12.4%). Male patients were more likely to have lung damage and emphysema, while female patients were more likely to have bronchiectasis. Conclusions　The distribution of NTM species is diverse in Hainan area, with Mycobacterium intracellulare, Mycobacterium chelonae/abscessus, and Mycobacterium avium are dominant species. NTM pulmonary disease and pulmonary tuberculosis have similar clinical features, which requires attention for differentiation in clinical practice.

Objective To study the effect of extracellular matrix(ECM)of xenogenic femoral fascia which is a tissue-engineering material in repair of renal trauma.Methods Twenty-four experiment dogs were divided into 3 groups:group 1(n=10),the kidneys were repaired using ECM of xenogenic femoral fascia;group 2(n=10),the kidneys were repaired using self-omentum;group 3(n=4),xenogenic femoral fascia was used as repair materials.The animals were sacrificed separately at 1,2 weeks and 1,2,4 months after renal repair operations in group 1,2.In group 3,the animals were sacrificed separately at 2 weeks and 2 months after renal repair operations.The examinations of blood routine were performed before and after operations immediately,blood creatinine and serum renin were measured before operations and before death.The creatinine clearances of affected and contralateral normal kidneys were evaluated before death and the local areas of renal repair were studied by light and scan electron microscopy.Results In group 1,bleeding stopped rapidly and completely after the entire patch was sutured,only mild adhesions to surrounding tissues were found in various times after operations.As time passed,the repair patch was replaced by smooth neocapsule just like a normal one.In group 2,the bleeding volume in the operations was larger than the other 2 groups.It was diffieult tO separate the kidneys from the surrounding tissues.The wounds gradually contracted because of the scar forming.In group 3,there were severe immunological reactions in the patchs.Conclusion ECM of xenogenic femoral fascia is an ideal tissue-enginee rjng material for renal repair.

Objective: To study the effect of extracellula matrix of xenogenic femoral fascia in repair of renal trauma. Methods: Twelve adult dogs were used and randomly assigned to 6 groups, and the animals were sacrificed separately in 1 and 2 weeks 1,2,4 and 8 months after renal repair operations. The examinations of blood and urine routine, blood urea nitrogen and creatinine, electrolyte and serum renin were performed before and after operations at various times. The creatinine clearances of affected and contralateral normal kidneys were evaluated before death and the local areas of renal repair were studied by light and electron microscopy. Results: Bleeding was stopped completely after the entire patch was sutured, and only mild adhesions to around tissues were found in various times after operations. As time passed, the repair patch was replaced by smooth neocapsule like normal renal capsule. Conclusion: Extracellula matrix of xenogenic femoral fascia might be an ideal tissue-engineering material for renal repair.

Objective To present our experience of dealing with complete penile amputation.Methods Two cases of penile complete amputation were reported.The first case was a 34-year-old man,suffered amputation of the penis approximately 2.5 cm distal from the pubic area with a sharp knife.3.5hours later,the patient was transferred to our hospital.The urethra mucosa and corpus spongiosum were anastomosed.The cavernous body of the penis was reattached by suturing the tunics albuginea of each corpus cavernosum to the corresponding proximal segment.One dorssl artery,two dorsal veins,and dorsal nerve were anastomosed under a 10 × microscope with interrupted 9-0 nylon nonabsorbable sutures.The second case was a 25-year-old man,presented to the emergency room 15 hours after distal penile amputation,which had 2 wounds as a result of self-mutilation caused by psychiatric problems.The urethra mucosa and corpus spongiosum were anastomosed.The cavernous body of the penis was reattached by suturing the tunics albuginea of each corpus cavemosum to the corresponding proximal segment using 4-0 polyglactic acid sutures.Results In the first case,the tourniquet was released after replantation,and the distal penis appeared to revascularize,as noted by the gradual increase in redness and size.An arterial pulse was detected,and the superficial penile veins displayed normal turgor,and no bleeding was found.On postoperative day 3,the penile skin started to necrotize.On day 12,the necrotic skin was superficially debrided,and a fistula was observed in the corresponding urethral segment.Two weeks later,the fistula was sutured with 4-0 interrupted synthetic absorbable suture,and a transposition flap to embed the whole injured penis shaft was created from the proximal scrotal skin.The glans was exposed.Two months after the second operation,the embedded penis was released from the scrotum.After follow-up of two years,the patient had glans re-epithelialization with normal voiding,sensation,and erections.In the second case,the glans was still pink,but the penile skin started to necrotize on postoperative day 3.On day 14,serious infections were noted,the necrotic skin was superficially debrided,and the amputated penis was relieved.Conclusions Prompt diagnosis and early treatment are essential to avoid the potential complications of ischemic necrosis and autoamputation.Venous outflow is a critical factor for success of replantation.Microsurgical reanastomosing of the dorsal penile vein,penile arteries,and dorsal nerves can be identified as the standard method for penile replantation.The bipedicled scrotal flap can provide adequate skin cover for penis defects.

Purpose To study the effects of different doses of ultrasound contrast agent SonoVue upon contrast-enhanced ultrasound (CEUS) in the kidney of healthy rabbits, and to seek the optimal dose of SonoVue. Materials and Methods CEUS was performed in 10 healthy rabbits with GE LOGIQ-E9 by using 8 different doses of SonoVue (ranging from 0.02 ml/kg to 0.16 ml/kg). The quantitative parameters of the time-intensity curve (TIC) were measured and statistically compared. Results The TICs showed that the peak intensity (PI) and the area under curve (AUC) increased with dose when the doses ranged from 0.02 ml/kg to 0.10 ml/kg (r=0.962 and 0.965, P<0.05); when the dose further increased, AUC had little change but PI decreased reversely. The arrival time (AT) shortened along with the increase of the SonoVue dose (r= - 0.917, P<0.05). The dose had a positive correlation with time to peak (r=0.49, P<0.05). Conclusion The parameters of TIC are influenced intensely by different doses of SonoVue. It is important to realize the relationship between SonoVue doses and its effects upon contrast-enhancement ultrasound in microcirculatory quantification. The dose of 0.10 ml/kg appears to be the optimal dose for CEUS in examining kidney of healthy rabbit.
